Description

電源装置、照明ランプおよび照明装置Power supply device, illumination lamp, and illumination device
　本発明は電源装置、照明ランプおよび照明装置に係り、グロースタータ形照明器具に取り付け可能なＬＥＤランプに用いられる電源装置、それを用いたＬＥＤランプおよびＬＥＤ照明装置に関する。 The present invention relates to a power supply device, an illumination lamp, and an illumination device, and more particularly to a power supply device used for an LED lamp that can be attached to a glow starter type lighting fixture, and an LED lamp and an LED illumination device using the power supply device.
　従来使用されている蛍光ランプの点灯方式は、主にグロースタータ形、ラピッドスタート形、高周波点灯専用形（インバータ形）の３通りに大別される。このうち、グロースタータ形は、点灯装置を含む照明器具を簡素に設計できること、および低価格であることから広く普及している。グロースタータ形の点灯方式では、直管タイプのＦＬ管、環タイプのＦＣＬ管といった専用ランプとグロースタータが用いられる。 Fluorescent lamp lighting methods that have been used in the past are roughly divided into three types: glow starter type, rapid start type, and dedicated high frequency lighting type (inverter type). Among these, the glow starter type is widely used because it can simply design a lighting fixture including a lighting device and is inexpensive. In the glow starter type lighting method, a dedicated lamp such as a straight tube type FL tube or a ring type FCL tube and a glow starter are used.
　近年、グロースタータ形の照明装置において蛍光ランプの代替としてＬＥＤランプを使用する方法が提案されている（例えば、特許文献１～３）。この方法では、使用者が蛍光ランプをＬＥＤランプへ交換する作業のみで、容易にＬＥＤ照明装置への置き換えができる。このため、この方法は益々普及が加速すると考えられる。一方、非特許文献１には、グロースタータ形の照明器具に対してＬＥＤランプを装着する方法について国際基準が規定されている。 Recently, a method of using an LED lamp as an alternative to a fluorescent lamp in a glow starter type illumination device has been proposed (for example, Patent Documents 1 to 3). In this method, the user can easily replace the LED lamp with an LED illumination device only by replacing the fluorescent lamp with the LED lamp. For this reason, this method is expected to accelerate the spread. On the other hand, Non-Patent Document 1 stipulates an international standard for a method of mounting an LED lamp on a glow starter-type lighting fixture.

　特許文献１～３に開示されたＬＥＤ照明装置は、いずれも非特許文献１に開示された国際基準を前提としていない。国際基準（ＩＥＣ６２７７６　Ｅｄｉｔｉｏｎ　１．０　２０１４－１２）に基づいて、グロースタータ形の照明装置からＬＥＤ照明装置を構成する場合、蛍光ランプとＬＥＤランプを交換し、グロースタータとダミースタータを交換する。この方法では、グロースタータとダミースタータを交換するのを忘れ易い。ここで、グロースタータとダミースタータを交換するのを忘れると、ＬＥＤランプに高電圧が印加される場合がある。このとき、照明装置が高温になる可能性がある。 None of the LED lighting devices disclosed in Patent Documents 1 to 3 are based on the international standards disclosed in Non-Patent Document 1. Based on the international standard (IEC62776 Edition 1.0 2014-12), when the LED lighting device is composed of the glow starter type lighting device, the fluorescent lamp and the LED lamp are exchanged, and the glow starter and the dummy starter are exchanged. In this method, it is easy to forget to replace the glow starter and the dummy starter. Here, if it is forgotten to replace the glow starter and the dummy starter, a high voltage may be applied to the LED lamp. At this time, there is a possibility that the lighting device becomes hot.
　本発明は、上述の問題点を解決するためになされたもので、第１の目的は、グロースタータ形の照明装置において、蛍光ランプが、半導体発光素子を搭載した照明ランプと交換され、グロースタータとダミースタータの交換がされなかった場合に、照明装置を高温から保護する事ができる電源装置を得ることである。

A first object of the present invention is to provide a glow starter type lighting device in which a fluorescent lamp is replaced with an illumination lamp equipped with a semiconductor light emitting element. When the dummy starter is not replaced, a power supply device that can protect the lighting device from high temperatures is obtained.

　本発明に係る電源装置は、グロースタータ形の照明器具に取り付けるための、半導体発光素子を搭載した照明ランプの電源装置であって、第１入力端と、第２入力端と、を有している入力端と、入力端と、該入力端に接続され、該半導体発光素子を点灯させるための電圧を生成する電源回路と、該入力端と該電源回路との間に接続されたヒューズと、を備えている。 A power supply device according to the present invention is a power supply device for an illumination lamp equipped with a semiconductor light emitting element for mounting on a glow starter-type lighting fixture, and has a first input end and a second input end. An input terminal, an input terminal, a power supply circuit connected to the input terminal and generating a voltage for lighting the semiconductor light emitting element, a fuse connected between the input terminal and the power supply circuit, It has.
　また、本発明にかかる電源装置は、グロースタータ形の照明器具に取り付けるための、半導体発光素子を搭載した照明ランプの電源装置であって、第１入力端と、第２入力端と、を有している入力端と、該入力端に接続され、該半導体発光素子を点灯させるための電圧を生成する電源回路と、該入力端と該電源回路との間において、一端に該第１入力端が接続され、他端に該第２入力端が接続されたコンデンサと、を備えている。 A power supply device according to the present invention is a power supply device for an illumination lamp equipped with a semiconductor light emitting element for mounting on a glow starter-type lighting fixture, and has a first input end and a second input end. An input terminal connected to the input terminal and generating a voltage for lighting the semiconductor light emitting element, and the first input terminal at one end between the input terminal and the power circuit. And a capacitor having the other end connected to the second input end.
　さらに、本発明に係る電源装置は、グロースタータ形の照明器具に取り付けるための、半導体発光素子を搭載した照明ランプの電源装置であって、第１入力端と、第２入力端と、を有している入力端と、該入力端に接続され、該半導体発光素子を点灯させるための電圧を生成する電源回路と、該入力端と該電源回路との間において、一端に該第１入力端が接続され、他端に該第２入力端が接続され、該第１入力端と該第２入力端との間に印加される電圧が閾値よりも高くなると抵抗値が低くなる保護部と、を備えている。 Furthermore, a power supply device according to the present invention is a power supply device for an illumination lamp mounted with a semiconductor light emitting element for mounting on a glow starter-type lighting fixture, and has a first input end and a second input end. An input terminal connected to the input terminal and generating a voltage for lighting the semiconductor light emitting element, and the first input terminal at one end between the input terminal and the power circuit. Is connected, and the second input terminal is connected to the other end, and when the voltage applied between the first input terminal and the second input terminal becomes higher than a threshold value, a protection unit whose resistance value is reduced, It has.
　本発明における電源装置では、入力端と電源回路との間にヒューズが設けられる。電源装置が高温になるとヒューズが溶断する。このとき、入力端と電源回路の接続が遮断される。従って、電源装置への電源供給が停止する。この結果、電源装置への高電圧の印加が停止され、照明装置の温度上昇を抑制することが出来る。このため、照明装置を高温から保護することが出来る。 In the power supply device according to the present invention, a fuse is provided between the input terminal and the power supply circuit. When the power supply becomes hot, the fuse blows. At this time, the connection between the input terminal and the power supply circuit is cut off. Accordingly, the power supply to the power supply device is stopped. As a result, the application of high voltage to the power supply device is stopped, and the temperature rise of the lighting device can be suppressed. For this reason, an illuminating device can be protected from high temperature.
　また、本発明における電源装置では、入力端と電源回路との間にコンデンサが設けられる。コンデンサの容量によって、電源装置の入力インピーダンスが調整される。照明装置において、グロースタータとダミースタータの交換が実施されていない状態では、電源装置の入力インピーダンスの調整によって、グロースタータに印加される電圧が調整される。従って、コンデンサの容量の調整により、グロースタータに印加される電圧が調整できる。グロースタータに印加される電圧を、グロースタータが放電状態と導通状態を交互に繰り返すような電圧に調整すると、照明ランプは点灯と消灯を交互に繰り返すことになる。このとき、照明ランプの点滅によってグロースタータの交換が行われていないことを使用者に通知することができる。従って、使用者にグロースタータとダミースタータの交換を促す事ができる。 Further, in the power supply device according to the present invention, a capacitor is provided between the input terminal and the power supply circuit. The input impedance of the power supply device is adjusted by the capacitance of the capacitor. In the lighting device, when the glow starter and the dummy starter are not exchanged, the voltage applied to the glow starter is adjusted by adjusting the input impedance of the power supply device. Therefore, the voltage applied to the glow starter can be adjusted by adjusting the capacitance of the capacitor. If the voltage applied to the glow starter is adjusted to a voltage that causes the glow starter to alternately repeat the discharge state and the conduction state, the illumination lamp will alternately turn on and off. At this time, the user can be notified that the glow starter has not been replaced by the blinking of the illumination lamp. Accordingly, it is possible to prompt the user to replace the glow starter and the dummy starter.
　さらに、本発明における電源装置では、入力端と電源回路との間において、第１入力端子と第２入力端子の間に保護部が接続される。入力端に閾値よりも高い電圧が印加されると、保護部の抵抗値が低くなる。従って、入力端に高電圧が印加された場合、保護部の抵抗値が低下し、高電圧成分がバイパスされる。この結果、電源回路に高電圧が印加されるのを防止する事が可能になる。従って、照明装置を高電圧から保護することが出来る。 Furthermore, in the power supply device according to the present invention, a protection unit is connected between the first input terminal and the second input terminal between the input terminal and the power supply circuit. When a voltage higher than the threshold value is applied to the input terminal, the resistance value of the protection unit decreases. Therefore, when a high voltage is applied to the input terminal, the resistance value of the protection unit decreases and the high voltage component is bypassed. As a result, it is possible to prevent a high voltage from being applied to the power supply circuit. Therefore, the lighting device can be protected from a high voltage.

　図１は、グロースタータ形の蛍光灯照明システム８８のブロック図である。蛍光灯照明システム８８はグロースタータ形である。蛍光灯照明システム８８では、始動装置であるグロースタータ８２０を用いて蛍光ランプ９００のフィラメントを予熱して点灯させる。蛍光灯照明システム８８では、外部供給電源５０からグロースタータ形照明装置８０に電力が供給される。外部供給電源５０は、商用交流電源である。 Embodiment 1 FIG.
FIG. 1 is a block diagram of a glow starter-type fluorescent lamp illumination system 88. The fluorescent lighting system 88 is a glow starter type. In the fluorescent lamp illumination system 88, the filament of the fluorescent lamp 900 is preheated and lit using a glow starter 820 as a starting device. In the fluorescent lamp illumination system 88, power is supplied from the external supply power supply 50 to the glow starter illumination device 80. The external supply power source 50 is a commercial AC power source.
　グロースタータ形照明装置８０は、グロースタータ形の照明器具１００に蛍光ランプ９００およびグロースタータ８２０を取り付けることで構成される。グロースタータ形の照明器具１００は、点灯装置１１０、ソケット８５１およびグローソケット８４１を備える。ソケット８５１には、蛍光ランプ９００が取り付けられる。ソケット８５１は、蛍光ランプ９００の接続に適合した形状のソケットである。また、グローソケット８４１にはグロースタータ８２０が取り付けられる。グローソケット８４１は、グロースタータ８２０の接続に適合した形状のソケットである。本実施の形態において、照明器具１００は、トラフ型、笠付き、逆富士型、逆富士型（２灯用）、埋め込み型の形状のものを含む。 The glow starter type lighting device 80 is configured by attaching a fluorescent lamp 900 and a glow starter 820 to a glow starter type lighting apparatus 100. The glow starter-type lighting fixture 100 includes a lighting device 110, a socket 851, and a glow socket 841. A fluorescent lamp 900 is attached to the socket 851. The socket 851 is a socket having a shape suitable for the connection of the fluorescent lamp 900. A glow starter 820 is attached to the glow socket 841. The glow socket 841 is a socket having a shape adapted to the connection of the glow starter 820. In the present embodiment, the lighting fixture 100 includes trough type, shaded, reverse Fuji type, reverse Fuji type (for two lights), and embedded type.
　蛍光灯照明システム８８では、外部供給電源５０、グロースタータ形の点灯装置１１０および蛍光ランプ９００が直列回路を形成する。蛍光ランプ９００にはグロースタータ８２０が並列に接続される。 In the fluorescent lamp illumination system 88, the external power supply 50, the glow starter type lighting device 110, and the fluorescent lamp 900 form a series circuit. A glow starter 820 is connected to the fluorescent lamp 900 in parallel.
　点灯装置１１０は、磁気式安定器である。磁気式安定器は、磁気回路式安定器または銅鉄型安定器とも呼ばれる。点灯装置１１０は、グロースタータ形の蛍光灯照明システム８８において蛍光ランプ９００を点灯させる規格を備える。点灯装置１１０は磁気を通す鉄心に銅の巻線を巻きつけた構造のチョークコイルを備える。チョークコイルの電気特性により、蛍光ランプ９００は放電を開始する。また、チョークコイルは蛍光ランプ９００の放電状態を安定に維持させる。また、点灯装置１１０において、チョークコイルのインダクタンスを調整することによって、グロースタータ８２０の放電電流を制御することができる。 The lighting device 110 is a magnetic ballast. Magnetic ballasts are also called magnetic circuit ballasts or copper iron ballasts. The lighting device 110 has a standard for lighting the fluorescent lamp 900 in the glow starter-type fluorescent lamp illumination system 88. The lighting device 110 includes a choke coil having a structure in which a copper winding is wound around an iron core that passes magnetism. Due to the electrical characteristics of the choke coil, the fluorescent lamp 900 starts discharging. The choke coil maintains the discharge state of the fluorescent lamp 900 stably. In the lighting device 110, the discharge current of the glow starter 820 can be controlled by adjusting the inductance of the choke coil.
　蛍光ランプ９００は、グロースタータ形の蛍光ランプである。本実施の形態において、蛍光ランプ９００は直管蛍光ランプである。 The fluorescent lamp 900 is a glow starter type fluorescent lamp. In the present embodiment, the fluorescent lamp 900 is a straight tube fluorescent lamp.
　グロースタータ８２０は、蛍光ランプ９００のフィラメントに予熱電流を流すための電流経路となる。また、グロースタータ８２０は、蛍光ランプ９００が備えるフィラメント間に放電電圧を発生させる機能を備える。グロースタータ８２０は端子対８２２を備える。端子対８２２は、第１端子８２２ａと第２端子８２２ｂから構成される。第１端子８２２ａおよび第２端子８２２ｂには電極が接続されている。第１端子８２２ａおよび第２端子８２２ｂに接続される電極のうち、少なくとも一方は可動電極である。 The glow starter 820 serves as a current path for allowing a preheating current to flow through the filament of the fluorescent lamp 900. In addition, the glow starter 820 has a function of generating a discharge voltage between filaments included in the fluorescent lamp 900. The glow starter 820 includes a terminal pair 822. The terminal pair 822 includes a first terminal 822a and a second terminal 822b. Electrodes are connected to the first terminal 822a and the second terminal 822b. At least one of the electrodes connected to the first terminal 822a and the second terminal 822b is a movable electrode.
　グロースタータ８２０は、部品仕様として放電開始電圧ＶＤｐが設定されている。第１端子８２２ａと第２端子８２２ｂとの間に放電開始電圧ＶＤｐを超える端子間電圧ＶＤが印加されると端子対８２２間で放電が生じる。この時、グロースタータ８２０は放電状態となる。放電に伴う温度上昇によって、可動電極が変形する。この結果、端子対８２２に接続される電極どうしが接触する。この時、グロースタータ８２０は導通状態となる。導通状態では、放電は生じないため電極の温度が降下する。温度降下により、可動電極は温度上昇時とは逆に変形する。この結果、端子対８２２に接続される電極どうしは再び離間する。 In the glow starter 820, a discharge start voltage V Dp is set as a component specification. When the inter-terminal voltage V D exceeding the discharge start voltage V Dp is applied between the first terminal 822a and the second terminal 822b, a discharge occurs between the terminal pair 822. At this time, the glow starter 820 is in a discharged state. The movable electrode is deformed by the temperature rise accompanying the discharge. As a result, the electrodes connected to the terminal pair 822 come into contact with each other. At this time, the glow starter 820 becomes conductive. In the conductive state, discharge does not occur, so the electrode temperature drops. Due to the temperature drop, the movable electrode is deformed in reverse to the temperature rise. As a result, the electrodes connected to the terminal pair 822 are separated again.
　次に、蛍光灯照明システム８８について説明する。蛍光灯照明システム８８は、外部供給電源５０がグロースタータ形照明装置８０に供給されることによって動作する。外部供給電源５０から交流電力が供給されるとグロースタータ８２０が放電状態となる。放電に伴う温度上昇によって、端子対８２２に接続される電極どうしが接触する。この結果、グロースタータ８２０は導通状態となる。この時、蛍光灯照明システム８８は閉回路を形成する。このため、蛍光ランプ９００のフィラメントに電流が流れ、フィラメントが予熱される。 Next, the fluorescent lamp illumination system 88 will be described. The fluorescent lamp illumination system 88 operates by supplying an external power supply 50 to the glow starter illumination device 80. When AC power is supplied from the external power supply 50, the glow starter 820 enters a discharge state. The electrodes connected to the terminal pair 822 come into contact with each other due to the temperature rise caused by the discharge. As a result, the glow starter 820 becomes conductive. At this time, the fluorescent lamp illumination system 88 forms a closed circuit. For this reason, an electric current flows through the filament of the fluorescent lamp 900, and the filament is preheated.
　このとき、グロースタータ８２０は導通状態であり、温度降下が生じる。従って、端子対８２２に接続される電極どうしは再び離間する。電極どうしが離間すると蛍光灯照明システム８８は回路が開放される。このとき、点灯装置１１０の両端に高い逆起電力が発生する。逆起電力は、千数百Ｖ程度である。この逆起電力がトリガとなり、蛍光ランプ９００は予熱されたフィラメント間で放電を開始する。この結果、蛍光ランプ９００は点灯する。 At this time, the glow starter 820 is in a conductive state and a temperature drop occurs. Therefore, the electrodes connected to the terminal pair 822 are separated again. When the electrodes are separated from each other, the circuit of the fluorescent lamp illumination system 88 is opened. At this time, a high back electromotive force is generated at both ends of the lighting device 110. The counter electromotive force is about a few hundreds of volts. The counter electromotive force serves as a trigger, and the fluorescent lamp 900 starts discharging between the preheated filaments. As a result, the fluorescent lamp 900 is turned on.
　蛍光ランプ９００がフィラメント間で放電を持続し、点灯している状態では、端子対８２２間の電圧が放電開始電圧ＶＤｐを下回る。このとき、グロースタータ８２０は放電状態でも接触状態でもない停止状態となる。 When the fluorescent lamp 900 continues to discharge between the filaments and is lit, the voltage between the terminal pair 822 is lower than the discharge start voltage V Dp . At this time, the glow starter 820 is in a stopped state that is neither in a discharged state nor in a contact state.
　図２は、本発明の実施の形態１のＬＥＤ照明システム１１のブロック図である。ＬＥＤ照明システム１１は、蛍光灯照明システム８８から蛍光ランプ９００およびグロースタータ８２０を取り外し、照明ランプ３００およびダミースタータ１２０を取り付けることで構成される。ＬＥＤ照明システム１１において、外部供給電源５０から照明装置１０に電力が供給される。照明装置１０は、グロースタータ形の照明器具１００、照明ランプ３００およびダミースタータ１２０を備える。 FIG. 2 is a block diagram of the LED lighting system 11 according to the first embodiment of the present invention. The LED illumination system 11 is configured by removing the fluorescent lamp 900 and the glow starter 820 from the fluorescent lamp illumination system 88 and attaching the illumination lamp 300 and the dummy starter 120. In the LED lighting system 11, electric power is supplied from the external power supply 50 to the lighting device 10. The lighting device 10 includes a glow starter-type lighting fixture 100, an illumination lamp 300, and a dummy starter 120.
　照明ランプ３００には、半導体発光素子が搭載されている。本実施の形態において、半導体発光素子はＬＥＤ素子である。ダミースタータ１２０は、グローソケット８４１を導通する機能を備える。ＬＥＤ照明システム１１は、外部供給電源５０、半導体発光素子に点灯電力を供給するための電源装置３２０、点灯装置１１０およびダミースタータ１２０が直列に接続された構成である。 The illumination lamp 300 is equipped with a semiconductor light emitting element. In the present embodiment, the semiconductor light emitting element is an LED element. The dummy starter 120 has a function of conducting the glow socket 841. The LED illumination system 11 has a configuration in which an external power supply 50, a power supply device 320 for supplying lighting power to a semiconductor light emitting element, a lighting device 110, and a dummy starter 120 are connected in series.
　照明ランプ３００は、ソケット８５１に装着可能な口金を備える。口金は、外部供給電源５０側に接続される第１口金３５０および、点灯装置１１０側に接続される第２口金３５６から構成される。照明ランプ３００は、第１口金３５０および第２口金３５６によって、照明器具１００に固定される。第１口金３５０は、端子対３５１を備える。第２口金３５６は端子対３５７を備える。端子対３５１、３５７はソケット８５１と接続される。 The illumination lamp 300 includes a base that can be attached to the socket 851. The base includes a first base 350 connected to the external power supply 50 side and a second base 356 connected to the lighting device 110 side. The illumination lamp 300 is fixed to the luminaire 100 by a first base 350 and a second base 356. The first base 350 includes a terminal pair 351. The second base 356 includes a terminal pair 357. Terminal pairs 351 and 357 are connected to socket 851.
　本実施の形態において、照明ランプ３００は直管ＬＥＤランプである。照明ランプ３００は、電源装置３２０、発光部３１０、配線部および外郭部を備える。電源装置３２０は半導体発光素子を点灯させるための電圧を生成する。発光部３１０は半導体発光素子を搭載している。配線部は、電源配線部材３３２および光源配線部材３３３を備える。外郭部は、カバー３４０、第１口金３５０および第２口金３５６から構成される。電源装置３２０および発光部３１０は外郭部の内部に配置される。カバー３４０は透光性を備える。 In this embodiment, the illumination lamp 300 is a straight tube LED lamp. The illumination lamp 300 includes a power supply device 320, a light emitting unit 310, a wiring unit, and an outline unit. The power supply device 320 generates a voltage for lighting the semiconductor light emitting element. The light emitting unit 310 is equipped with a semiconductor light emitting element. The wiring unit includes a power supply wiring member 332 and a light source wiring member 333. The outer portion includes a cover 340, a first base 350, and a second base 356. The power supply device 320 and the light emitting unit 310 are disposed inside the outer portion. The cover 340 has translucency.
　端子対３５１を介して、外部供給電源５０から電源装置３２０に電力が供給される。従って、第１口金３５０は給電口金となる。第２口金３５６が備える端子対３５７の内部はヒューズ３３６を介して導通している。従って、端子対３５７は点灯装置１１０とダミースタータ１２０との間を導通する機能を備える。なお、ヒューズ３３６の溶断特性は、点灯装置１１０の特性に応じて選択される。例えば、長さが２ｆｔである蛍光ランプ９００に適合した点灯装置１１０と接続される照明ランプ３００では、溶断電流が１６０ｍＡ程度のヒューズ３３６を選択するとよい。また、例えば、長さが４ｆｔである蛍光ランプ９００に適合した点灯装置１１０と接続される照明ランプ３００では、溶断電流が２００ｍＡ程度のヒューズ３３６を選択するとよい。 Power is supplied from the external power supply 50 to the power supply device 320 via the terminal pair 351. Accordingly, the first base 350 serves as a power supply base. The inside of the terminal pair 357 provided in the second base 356 is electrically connected through the fuse 336. Therefore, the terminal pair 357 has a function of conducting between the lighting device 110 and the dummy starter 120. Note that the fusing characteristics of the fuse 336 are selected according to the characteristics of the lighting device 110. For example, in the illumination lamp 300 connected to the lighting device 110 suitable for the fluorescent lamp 900 having a length of 2 ft, the fuse 336 having a fusing current of about 160 mA may be selected. For example, in the illumination lamp 300 connected to the lighting device 110 suitable for the fluorescent lamp 900 having a length of 4 ft, the fuse 336 having a fusing current of about 200 mA may be selected.
　ダミースタータ１２０は、グローソケット８４１を導通するために取り付けられる。ダミースタータ１２０はグローソケット８４１に対応した端子１２２を備える。端子１２２は第１端子１２２ａおよび第２端子１２２ｂから構成される。第１端子１２２ａは照明ランプ３００の第１口金３５０側と接続される。第２端子１２２ｂは照明ランプ３００の第２口金３５６側と接続される。 The dummy starter 120 is attached to make the glow socket 841 conductive. The dummy starter 120 includes a terminal 122 corresponding to the glow socket 841. The terminal 122 includes a first terminal 122a and a second terminal 122b. The first terminal 122 a is connected to the first base 350 side of the illumination lamp 300. The second terminal 122b is connected to the second base 356 side of the illumination lamp 300.
　図３は、本発明の実施の形態１に係る照明ランプの回路ブロック図（その１）である。第１口金３５０が備える端子対３５１は、電源配線部材３３２を介して電源装置３２０が備える入力端３２９と接続される。このため、電源装置３２０は入力端３２９から交流電力を受電する。交流電力は入力部３２３を介して電源回路３３０に入力される。 FIG. 3 is a circuit block diagram (part 1) of the illumination lamp according to the first embodiment of the present invention. The terminal pair 351 provided in the first base 350 is connected to the input end 329 provided in the power supply device 320 via the power supply wiring member 332. For this reason, the power supply device 320 receives AC power from the input terminal 329. The AC power is input to the power supply circuit 330 through the input unit 323.
　電源回路３３０は、半導体発光素子を点灯させるための電圧を生成する。電源回路３３０に入力された交流電力は、整流部３２４に入力される。整流部３２４において交流電力は直流電力に変換される。整流部３２４の出力電力は平滑部３２５で平滑され、出力部３２６に入力される。出力部３２６の入力電力および出力電力は検出部３２８によって検知される。制御部３２７は、検出部３２８によって検知された電力値に基づいて出力部３２６を制御する。この結果、出力部３２６の出力電流が一定になるように、定電流制御が実施される。 The power supply circuit 330 generates a voltage for lighting the semiconductor light emitting element. The AC power input to the power supply circuit 330 is input to the rectifying unit 324. In the rectifying unit 324, AC power is converted into DC power. The output power of the rectifying unit 324 is smoothed by the smoothing unit 325 and input to the output unit 326. The input power and output power of the output unit 326 are detected by the detection unit 328. The control unit 327 controls the output unit 326 based on the power value detected by the detection unit 328. As a result, constant current control is performed so that the output current of the output unit 326 becomes constant.
　以上から、電源回路３３０において定電流が出力される。従って、電源装置３２０は定電流回路となる。定電流負荷である発光部３１０には、光源配線部材３３３を介して電源装置３２０から電力が供給される。この結果、発光部３１０に搭載される半導体発光素子に、点灯のための直流電力が供給される。電源装置３２０は、外部供給電源５０から入力された交流電力を直流電力に変換するとともに発光部３１０に出力するＡＣ－ＤＣ変換回路である。 From the above, a constant current is output in the power supply circuit 330. Accordingly, the power supply device 320 is a constant current circuit. Power is supplied from the power supply device 320 to the light emitting unit 310 that is a constant current load via the light source wiring member 333. As a result, the DC power for lighting is supplied to the semiconductor light emitting element mounted on the light emitting unit 310. The power supply device 320 is an AC-DC conversion circuit that converts AC power input from the external power supply 50 into DC power and outputs the DC power to the light emitting unit 310.
　図４は、本発明の実施の形態１に係る照明ランプの回路ブロック図（その２）である。入力端３２９は第１入力端３２９ａおよび第２入力端３２９ｂを備える。入力部３２３はヒューズを備える。ヒューズは、入力端３２９と電源回路３３０との間に接続される。また、ヒューズは、第１ヒューズ３２３ａおよび第２ヒューズ３２３ｂを備える。第１ヒューズ３２３ａは、第１入力端３２９ａと電源回路３３０との間に接続される。第２ヒューズ３２３ｂは、第２入力端３２９ｂと電源回路３３０との間に接続される。 FIG. 4 is a circuit block diagram (part 2) of the illumination lamp according to Embodiment 1 of the present invention. The input terminal 329 includes a first input terminal 329a and a second input terminal 329b. The input unit 323 includes a fuse. The fuse is connected between the input terminal 329 and the power supply circuit 330. The fuse includes a first fuse 323a and a second fuse 323b. The first fuse 323 a is connected between the first input terminal 329 a and the power supply circuit 330. The second fuse 323 b is connected between the second input terminal 329 b and the power supply circuit 330.
　また、入力部３２３はヒューズと電源回路３３０との間において、コンデンサ３２３ｃを備える。コンデンサ３２３ｃは、一端が第１入力端３２９ａと接続され、他端が第２入力端３２９ｂと接続される。また、入力部３２３は、コンデンサ３２３ｃと電源回路３３０との間においてバリスタ３２３ｄを備える。バリスタ３２３ｄは、一端が第１入力端３２９ａと接続され、他端が第２入力端３２９ｂと接続される。整流部３２４はダイオード３２４ａを備える。 In addition, the input unit 323 includes a capacitor 323 c between the fuse and the power supply circuit 330. One end of the capacitor 323c is connected to the first input end 329a, and the other end is connected to the second input end 329b.

The second base 356 includes a terminal pair 357 and a housing 358. The housings 352 and 358 have a cylindrical shape. The first base 350 and the second base 356 have outer shapes that can be attached to the socket 851. Further, the terminal pairs 351 and 357 may have a terminal shape corresponding to the socket 851. As the terminal pairs 351 and 357, the G13 type or the GX16 type shown in FIGS. 5A to 5E can be employed.
　図６Ａは、本発明の実施の形態１に係る照明ランプ３００の構造を示す平面図である。図６Ｂは、本発明の実施の形態１に係る照明ランプ３００の構造を示す正面図である。図６Ｃは、本発明の実施の形態１に係る照明ランプ３００の構造を示す底面図である。図６Ｄは、本発明の実施の形態１に係る照明ランプ３００の構造を示す左側面図である。図６Ｅは、本発明の実施の形態１に係る照明ランプ３００の構造を示す右側面図である。なお、図６Ａ～Ｅにおいて、便宜上、外郭部の一部が省略されている。電源装置３２０は、電源基板３２２および回路部品３２１から構成される。回路部品３２１は、電源基板３２２に実装されている。また、電源基板３２２には配線パターンが形成される。配線パターンおよび回路部品３２１の一部は定電流回路を構成する。 FIG. 6A is a plan view showing a structure of illumination lamp 300 according to Embodiment 1 of the present invention. FIG. 6B is a front view showing the structure of the illumination lamp 300 according to Embodiment 1 of the present invention. FIG. 6C is a bottom view showing the structure of the illumination lamp 300 according to Embodiment 1 of the present invention. FIG. 6D is a left side view showing the structure of illumination lamp 300 according to Embodiment 1 of the present invention. FIG. 6E is a right side view showing the structure of illumination lamp 300 according to Embodiment 1 of the present invention. 6A to 6E, a part of the outer portion is omitted for convenience. The power supply device 320 includes a power supply board 322 and circuit components 321. The circuit component 321 is mounted on the power supply board 322. A wiring pattern is formed on the power supply substrate 322. A part of the wiring pattern and the circuit component 321 constitutes a constant current circuit.
　電源基板３２２は、電源基板３２２の法線方向が照明ランプ３００の長手方向に対して垂直になるように配置される。電源装置３２０は筐体３５２に保持された状態で、第１口金３５０の内部に一部が収納されている。電源装置３２０のうち、第１口金３５０から露出する部分はカバー３４０の内部に収納されている。この構成では、電源装置３２０を第１口金３５０に収まるように配置される場合と比較して、電源基板３２２の面積を大きくすることが出来る。このため、電源基板３２２上に配置される回路部品３２１間の間隔を広く確保することが可能になる。従って、放熱性が向上し、電源装置３２０の動作熱の発生を分散させることが可能になる。 The power supply board 322 is arranged so that the normal direction of the power supply board 322 is perpendicular to the longitudinal direction of the illumination lamp 300. A part of the power supply device 320 is housed inside the first base 350 while being held in the housing 352. A portion of the power supply device 320 exposed from the first base 350 is housed in the cover 340. In this configuration, the area of the power supply substrate 322 can be increased as compared with the case where the power supply device 320 is disposed so as to be accommodated in the first base 350. For this reason, it is possible to ensure a wide interval between the circuit components 321 arranged on the power supply substrate 322. Therefore, heat dissipation is improved, and the generation of operating heat of the power supply device 320 can be dispersed.
　照明ランプ３００において、筐体３５２、３５８およびカバー３４０に樹脂を採用することがある。本実施の形態では、電源基板３２２の面積を大きくすることで、電源装置３２０の発熱が抑制される。従って、樹脂部分が受ける熱量を抑制することが出来る。さらに、電源基板３２２の面積を大きくすることで、部品間の間隔が広くなる。従って、照明ランプ３００の外部から侵入する高電圧ノイズに対する絶縁耐性が向上する。 In the illumination lamp 300, resin may be used for the housings 352 and 358 and the cover 340. In the present embodiment, the heat generation of the power supply device 320 is suppressed by increasing the area of the power supply substrate 322. Therefore, the amount of heat received by the resin portion can be suppressed. Furthermore, by increasing the area of the power supply substrate 322, the interval between components is increased. Accordingly, the insulation resistance against high voltage noise entering from the outside of the illumination lamp 300 is improved.

　図１０は、グロースタータ形の照明器具１００にグロースタータ８２０および本発明の実施の形態１に係る照明ランプ３００が取り付けられた照明システム７７のブロック図である。グロースタータ形照明装置８０から本実施の形態に係る照明装置１０へのリニューアル施工では、蛍光ランプ９００と照明ランプ３００を交換し、グロースタータ８２０とダミースタータ１２０を交換する必要がある。このリニューアル施工では、グロースタータ８２０とダミースタータ１２０を交換するのを忘れ易い。 FIG. 10 is a block diagram of an illumination system 77 in which the glow starter 820 and the illumination lamp 300 according to Embodiment 1 of the present invention are attached to the glow starter-type lighting fixture 100. In the renewal construction from the glow starter type illumination device 80 to the illumination device 10 according to the present embodiment, it is necessary to replace the fluorescent lamp 900 and the illumination lamp 300 and replace the glow starter 820 and the dummy starter 120. In this renewal construction, it is easy to forget to replace the glow starter 820 and the dummy starter 120.
　図１０は、正しく施工されず、グロースタータ８２０を交換せずに、蛍光ランプ９００と照明ランプ３００が交換された状態の照明装置７０を示す。一般に、グロースタータを交換せずに、ＬＥＤランプが取り付けられた照明装置では、グロースタータが発生させる高電圧の逆起電力によって、ＬＥＤ照明装置が損傷する可能性がある。 FIG. 10 shows the illuminating device 70 in a state where the fluorescent lamp 900 and the illumination lamp 300 are replaced without replacing the glow starter 820 without being correctly constructed. In general, in an illuminating device in which an LED lamp is mounted without replacing the glow starter, the LED illuminating device may be damaged by a high voltage back electromotive force generated by the glow starter.
　ここで、図４で示したように、本実施の形態に係る電源装置３２０は、バリスタ３２３ｄを備える。バリスタは、バリアブル・レジスタ（ｖａｒｉａｂｌｅ　ｒｅｓｉｓｔｏｒ）とも呼ばれる。バリスタ３２３ｄは、両端に印加される電圧が閾値より低い場合には電気抵抗が非常に大きい。しかし、両端に印加される電圧が閾値よりも高い場合には電気抵抗が小さくなる。 Here, as shown in FIG. 4, the power supply apparatus 320 according to the present embodiment includes a varistor 323d. A varistor is also referred to as a variable register. The varistor 323d has a very large electric resistance when the voltage applied to both ends is lower than the threshold value. However, when the voltage applied to both ends is higher than the threshold value, the electrical resistance is reduced.
　バリスタ３２３ｄは、一端が第１入力端３２９ａと接続され、他端が第２入力端３２９ｂと接続される。グロースタータ８２０が高電圧を発生させると、端子対３５１を介して入力端３２９に高電圧が印加される。このとき、バリスタ３２３ｄの両端には閾値よりも高い電圧が印加される。従って、バリスタ３２３ｄは低抵抗となる。この結果、バリスタ３２３ｄがバイパスとなり、高電圧が電源回路３３０および発光部３１０に印加されるのを防止することが可能になる。 The varistor 323d has one end connected to the first input end 329a and the other end connected to the second input end 329b. When the glow starter 820 generates a high voltage, the high voltage is applied to the input terminal 329 via the terminal pair 351. At this time, a voltage higher than the threshold is applied to both ends of the varistor 323d. Therefore, the varistor 323d has a low resistance. As a result, the varistor 323d is bypassed, and it is possible to prevent a high voltage from being applied to the power supply circuit 330 and the light emitting unit 310.
　従って、本実施の形態に係る電源装置３２０では、照明システム７７のようにグロースタータ８２０が交換されなかった場合において、高電圧から電源回路３３０および半導体発光素子３１１を保護することが可能になる。従って、照明装置７０を高電圧による損傷から保護することが可能になる。 Therefore, in the power supply device 320 according to the present embodiment, it is possible to protect the power supply circuit 330 and the semiconductor light emitting element 311 from high voltage when the glow starter 820 is not replaced as in the illumination system 77. Therefore, it is possible to protect the lighting device 70 from damage due to a high voltage.
　また、ダミースタータ１２０が正しく取り付けられた照明装置１０において、照明ランプ３００または照明装置１０の外部から過大な電圧が印加される場合がある。バリスタ３２３ｄによって、このような高電圧からも照明装置１０を保護することができる。バリスタ３２３ｄは、５００Ｖ～１，５００Ｖの電圧をバイパスさせる特性を有する。また、バリスタ３２３ｄは５００Ｖ～１，５００Ｖの電圧耐性を備えている。 Further, in the lighting device 10 in which the dummy starter 120 is correctly attached, an excessive voltage may be applied from the outside of the lighting lamp 300 or the lighting device 10. The lighting device 10 can be protected from such a high voltage by the varistor 323d. The varistor 323d has a characteristic of bypassing a voltage of 500V to 1,500V. The varistor 323d has a voltage tolerance of 500V to 1,500V.
　本実施の形態では、電源装置３２０はバリスタ３２３ｄを備えるものとした。これに対し、バリスタ３２３ｄを、高電圧からの保護機能を備えた保護部と置き換えても良い。保護部は、第１入力端３２９ａと第２入力端３２９ｂとの間に印加される電圧が閾値よりも高くなると抵抗値が低くなる機能を備える。保護部には、ガスチューブアレスタ、マイクロギャップアレスタまたはシリコン系サージアブソーバーを使用することができる。 In this embodiment, the power supply device 320 includes the varistor 323d. On the other hand, the varistor 323d may be replaced with a protection unit having a protection function from a high voltage. The protection unit has a function of decreasing the resistance value when a voltage applied between the first input terminal 329a and the second input terminal 329b is higher than a threshold value. A gas tube arrester, a microgap arrester, or a silicon-based surge absorber can be used for the protective part.
　また、図４で示したように、電源装置３２０はコンデンサ３２３ｃを備える。コンデンサ３２３ｃは電源装置３２０の入力インピーダンスを調整している。照明装置７０において、外部供給電源５０が供給する交流電圧ＶＡＣは、点灯装置１１０、グロースタータ８２０および照明ランプ３００の入力インピーダンスで分圧される。コンデンサ３２３ｃは、グロースタータ８２０の端子対８２２に接続される電極間に放電開始電圧ＶＤｐを超える電圧が印加されるように容量値が選択されている。端子対８２２に接続される電極間に印加される電圧は、１５０Ｖ～１８０Ｖに設定する。 As shown in FIG. 4, the power supply device 320 includes a capacitor 323c. The capacitor 323 c adjusts the input impedance of the power supply device 320. A lighting device 70, an AC voltage V AC supplied by external power supply 50, the lighting device 110, is divided by the input impedance of the glow starter 820 and an illumination lamp 300. Capacitor 323 c has a capacitance value selected such that a voltage exceeding discharge start voltage V Dp is applied between electrodes connected to terminal pair 822 of glow starter 820. The voltage applied between the electrodes connected to the terminal pair 822 is set to 150V to 180V.
　図１１は、図１０に示す照明システム７７の動作を示すタイムチャート（その１）である。ＶＡＣ［Ｖ］は、外部供給電源５０から照明装置７０に入力される交流電圧を示す。ＴＧ［℃］は、グロースタータ８２０が備える可動電極の温度変化を示す。ＶＤ［Ｖ］は、グロースタータ８２０の電極間の電圧を示す。ＶＩＮ［Ｖ］は、電源装置３２０が備える入力端３２９に入力される交流電圧を示している。ＩＬＥＤ［Ａ］は、負荷回路である発光部３１０に流れる電流を示している。 FIG. 11 is a time chart (part 1) showing the operation of the illumination system 77 shown in FIG. V AC [V] represents an AC voltage input from the external power supply 50 to the lighting device 70. T G [° C.] indicates a temperature change of the movable electrode provided in the glow starter 820. V D [V] indicates a voltage between the electrodes of the glow starter 820. V IN [V] indicates an AC voltage input to the input terminal 329 included in the power supply device 320. I LED [A] indicates a current flowing through the light emitting unit 310 that is a load circuit.
　時刻ｔ０において、交流電力が外部供給電源５０から照明装置７０に供給されると、グロースタータ８２０の端子対８２２に接続される電極間に電圧が印加される。ここで、上述したように、コンデンサ３２３ｃは、グロースタータ８２０が備える電極間に放電開始電圧ＶＤｐを超える電圧が印加されるように容量値が選択されている。従って、グロースタータ８２０が備える電極間で放電が開始される（モード１）。放電に伴い、グロースタータ８２０が備える可動電極の温度が上昇する。モード１では、発光部３１０には点灯電力が供給されないので、照明ランプ３００は消灯状態となる。 When AC power is supplied from the external power supply 50 to the lighting device 70 at time t0, a voltage is applied between the electrodes connected to the terminal pair 822 of the glow starter 820. Here, as described above, the capacitance value of the capacitor 323c is selected so that a voltage exceeding the discharge start voltage V Dp is applied between the electrodes of the glow starter 820. Accordingly, discharge is started between the electrodes of the glow starter 820 (mode 1). Along with the discharge, the temperature of the movable electrode included in the glow starter 820 increases. In mode 1, since lighting power is not supplied to the light emitting unit 310, the illumination lamp 300 is turned off.
　グロースタータ８２０が備える可動電極は、温度の上昇に伴い変形する。この結果、時刻ｔ１において可動電極が規定の変形量に達し、グロースタータ８２０が備える電極どうしが接触する（モード２）。この結果、グロースタータ８２０は導通状態となる。モード２において、照明システム７７は閉回路を構成する。この時、発光部３１０には点灯電力が供給され、照明ランプ３００は点灯状態となる。 The movable electrode provided in the glow starter 820 is deformed as the temperature rises. As a result, the movable electrode reaches a predetermined deformation amount at time t1, and the electrodes included in the glow starter 820 come into contact with each other (mode 2). As a result, the glow starter 820 becomes conductive. In mode 2, the illumination system 77 constitutes a closed circuit. At this time, lighting power is supplied to the light emitting unit 310, and the illumination lamp 300 is turned on.
　モード２において、グロースタータ８２０が備える電極どうしは接触した状態であり、放電をしていない。このため、グロースタータ８２０が備える電極の温度は降下する。この結果、可動電極は逆に変形し、電極どうしは再び離間する。従って、照明装置７０は再びモード１に移行する。以降、照明システム７７はモード１とモード２を交互に繰り返す。 In mode 2, the electrodes of the glow starter 820 are in contact with each other and are not discharged. For this reason, the temperature of the electrode with which the glow starter 820 is provided falls. As a result, the movable electrodes are deformed in reverse, and the electrodes are separated again. Therefore, the lighting device 70 shifts to mode 1 again. Thereafter, the lighting system 77 repeats mode 1 and mode 2 alternately.
　このように、本実施の形態における電源装置３２０を用いると、グロースタータ８２０が交換されなかった場合に照明ランプ３００が点灯と消灯とを交互に繰り返す（以下、点滅ともいう）。グロースタータ８２０が交換されなかった場合に、照明ランプ３００は正常に点灯状態を継続することがなく、（正常ではない）点滅を繰り返す。このため、照明装置７０が正しく施工されていないことを使用者に通知することができる。従って、使用者にグロースタータ８２０とダミースタータ１２０の交換を促す事ができる。ここで、本実施の形態における使用者は、一般の消費者の他、専門の知識または資格を有する専門の施工業者を含む。 As described above, when the power supply device 320 in the present embodiment is used, when the glow starter 820 is not replaced, the illumination lamp 300 is alternately turned on and off (hereinafter also referred to as blinking). When the glow starter 820 is not replaced, the illumination lamp 300 does not continue to be lit normally and repeats blinking (not normal). For this reason, it can notify a user that the illuminating device 70 is not constructed | assembled correctly. Therefore, the user can be prompted to replace the glow starter 820 and the dummy starter 120. Here, the users in the present embodiment include professional contractors who have specialized knowledge or qualifications in addition to general consumers.
　可動電極の温度上昇速度は、グロースタータ８２０が備える電極間に印加される電圧によって決定される。従って、コンデンサ３２３ｃの容量値を調整することでモード１およびモード２の周期を調整できる。モード１およびモード２の周期は、使用者によって照明ランプ３００の点滅が視認されやすいように、数秒～十数秒の範囲で調整される。なお、コンデンサ３２３ｃの容量値を０．１５μＦ程度に調整すると、照明ランプ３００が視認されやすい点滅を繰り返す。 The temperature rise rate of the movable electrode is determined by the voltage applied between the electrodes of the glow starter 820. Therefore, the period of mode 1 and mode 2 can be adjusted by adjusting the capacitance value of capacitor 323c. The period of mode 1 and mode 2 is adjusted in the range of several seconds to several tens of seconds so that the user can easily recognize the blinking of the illumination lamp 300. When the capacitance value of the capacitor 323c is adjusted to about 0.15 μF, the illumination lamp 300 repeats blinking that is easy to visually recognize.
　モード１とモード２が切り替わる際には、点灯装置１１０の両端に高電圧の逆起電力が発生する。本実施の形態では、電源装置３２０はバリスタ３２３ｄを備える。このため、電源回路３３０を構成する回路部品３２１および半導体発光素子３１１を高電圧から保護することが出来る。 When the mode 1 and the mode 2 are switched, a high voltage back electromotive force is generated at both ends of the lighting device 110. In the present embodiment, the power supply device 320 includes a varistor 323d. For this reason, the circuit component 321 and the semiconductor light emitting element 311 constituting the power supply circuit 330 can be protected from a high voltage.
　また、ダミースタータ１２０が正しく取り付けられた照明装置１０において、照明ランプ３００または照明装置１０の外部から高い周波数のノイズが流入する場合がある。コンデンサ３２３ｃは、この外来ノイズをバイパスする機能を備える。このため、外来ノイズの電源回路３３０への流入が抑制される。従って、定電流回路の誤動作を防止することができる。 Also, in the lighting device 10 in which the dummy starter 120 is correctly attached, high frequency noise may flow from the outside of the lighting lamp 300 or the lighting device 10. The capacitor 323c has a function of bypassing this external noise. For this reason, the inflow of external noise to the power supply circuit 330 is suppressed. Therefore, malfunction of the constant current circuit can be prevented.
　図１２は、図１０に示す照明システム７７の動作を示すタイムチャート（その２）である。グロースタータ８２０が交換されていない照明システム７７では、点灯装置１１０の両端に高電圧の逆起電力が発生する場合がある。この高電圧により、照明装置７０の温度が上昇する可能性がある。 FIG. 12 is a time chart (part 2) showing the operation of the illumination system 77 shown in FIG. In the lighting system 77 in which the glow starter 820 is not replaced, a high-voltage counter electromotive force may be generated at both ends of the lighting device 110. This high voltage may increase the temperature of the lighting device 70.
　ここで、図４で示したように、本実施の形態における電源装置３２０は、第１ヒューズ３２３ａおよび第２ヒューズ３２３ｂを備える。電源装置３２０の温度が上昇し、規定の温度に達すると第１ヒューズ３２３ａまたは第２ヒューズ３２３ｂが溶断する。図４に示すように、第１ヒューズ３２３ａおよび第２ヒューズ３２３ｂは、入力端３２９と電源回路３３０との間に接続される。このため、第１ヒューズ３２３ａまたは第２ヒューズ３２３ｂが溶断することで、電源回路３３０への電源供給が停止する。従って、電源装置３２０の動作が停止する。この結果、照明装置７０の温度上昇が抑制される。 Here, as shown in FIG. 4, the power supply device 320 in the present embodiment includes a first fuse 323a and a second fuse 323b. When the temperature of the power supply device 320 rises and reaches a specified temperature, the first fuse 323a or the second fuse 323b is blown. As shown in FIG. 4, the first fuse 323 a and the second fuse 323 b are connected between the input terminal 329 and the power supply circuit 330. For this reason, the power supply to the power supply circuit 330 is stopped when the first fuse 323a or the second fuse 323b is melted. Accordingly, the operation of the power supply device 320 is stopped. As a result, the temperature rise of the lighting device 70 is suppressed.
　上述したように、本実施の形態に係る電源装置３２０を用いると、グロースタータ８２０が交換されていない照明システム７７において、照明ランプ３００が点滅する。モード１とモード２が切り替わる際の逆起電力は千数百Ｖ程度である。この逆起電力は、バリスタ３２３ｄによってバイパスされる。バリスタ３２３ｄは、バイパスされる逆起電力によって発熱し、徐々に温度が上昇する。図１２において、Ｔｐ［℃］は、照明システム７７を動作させた場合におけるバリスタ３２３ｄの温度推移の一例を示す。 As described above, when the power supply device 320 according to the present embodiment is used, the illumination lamp 300 blinks in the illumination system 77 in which the glow starter 820 is not replaced. The back electromotive force when the mode 1 and the mode 2 are switched is about several thousand V. This counter electromotive force is bypassed by the varistor 323d. The varistor 323d generates heat due to the counter electromotive force that is bypassed, and the temperature gradually rises. In FIG. 12, T p [° C.] shows an example of the temperature transition of the varistor 323d when the illumination system 77 is operated.
　図７Ａ～Ｃで示したように、本実施の形態に係る電源装置３２０では、第２ヒューズ３２３ｂは、バリスタ３２３ｄの外表面に接触するように配置される。また、第２ヒューズ３２３ｂは、接着部材３２３ｅによってバリスタ３２３ｄと固定されている。このように、第２ヒューズ３２３ｂは、バリスタ３２３ｄの温度を直接検知できるように配置されている。 As shown in FIGS. 7A to 7C, in the power supply apparatus 320 according to the present embodiment, the second fuse 323b is disposed so as to contact the outer surface of the varistor 323d. The second fuse 323b is fixed to the varistor 323d by an adhesive member 323e. Thus, the second fuse 323b is arranged so that the temperature of the varistor 323d can be directly detected.
　第２ヒューズ３２３ｂはバリスタ３２３ｄの温度を検知する。検知した温度が、温度ＴＦ［℃］に達すると第２ヒューズ３２３ｂは溶断する。つまり、第２ヒューズ３２３ｂはバリスタ３２３ｄの温度に応じて溶断する溶断特性を有する。ＴＦ［℃］は第２ヒューズ３２３ｂが溶断する温度である。第２ヒューズ３２３ｂが溶断することで、電源回路３３０への電源供給が停止する。これにより、図１２に示すようにバリスタ３２３ｄの温度が下降する。このとき、照明装置７０の温度上昇が抑制され、高温から照明装置７０を保護することが可能になる。 The second fuse 323b detects the temperature of the varistor 323d. When the detected temperature reaches the temperature T F [° C.], the second fuse 323b is blown. That is, the second fuse 323b has a fusing characteristic of fusing according to the temperature of the varistor 323d. T F [° C.] is a temperature at which the second fuse 323b is melted. When the second fuse 323b is blown, power supply to the power supply circuit 330 is stopped. As a result, the temperature of the varistor 323d decreases as shown in FIG. At this time, the temperature rise of the lighting device 70 is suppressed, and the lighting device 70 can be protected from a high temperature.
　以上から、本実施の形態に係る電源装置３２０を用いると、正しく施工されていない照明システム７７において、照明ランプ３００が点滅を繰り返す。これにより、グロースタータ８２０が交換されていないことを使用者に通知することができる。照明ランプ３００が点滅を繰り返している状態において点灯装置１１０の両端に発生する逆起電力は、バリスタ３２３ｄによってバイパスされる。このため、照明装置７０は高電圧から保護される。しかし、使用者が照明ランプ３００の点滅を認知できず、点滅が長時間にわたって継続して繰り返されると照明装置７０の温度が上昇する可能性がある。ここで、本実施の形態では、バリスタ３２３ｄの温度が上昇すると、第２ヒューズ３２３ｂが溶断する。従って、電源装置３２０の動作が停止し、照明装置７０の温度上昇が抑制される。以上から、第１口金３５０、照明ランプ３００、および照明装置７０が高温状態で損傷したり劣化したりすることを防止することが可能になる。 From the above, when the power supply device 320 according to the present embodiment is used, the illumination lamp 300 repeatedly blinks in the illumination system 77 that is not correctly constructed. As a result, the user can be notified that the glow starter 820 has not been replaced. Back electromotive force generated at both ends of the lighting device 110 in a state where the illumination lamp 300 repeats blinking is bypassed by the varistor 323d. For this reason, the illuminating device 70 is protected from a high voltage. However, if the user cannot recognize the blinking of the illumination lamp 300 and the blinking is repeated continuously for a long time, the temperature of the illumination device 70 may rise. Here, in the present embodiment, when the temperature of the varistor 323d rises, the second fuse 323b is blown. Therefore, the operation of the power supply device 320 is stopped, and the temperature rise of the lighting device 70 is suppressed. From the above, it is possible to prevent the first base 350, the illumination lamp 300, and the illumination device 70 from being damaged or deteriorated in a high temperature state.
　第２ヒューズ３２３ｂが溶断するまでの時間は、短い場合（ｔｆ１）は例えば３０秒程度、長い場合（ｔｆ３）は例えば３００秒程度である。第２ヒューズ３２３ｂが溶断するまでの時間は、回路部品３２１および第１口金３５０が備える筐体３５２の耐熱性を考慮して決定する。また、第２ヒューズ３２３ｂが溶断する温度ＴＦ［℃］は、電源装置３２０が備える回路部品３２１および第１口金３５０が備える筐体３５２の耐熱性を考慮して決定する。 The time until the second fuse 323b is blown is, for example, about 30 seconds when it is short (t f1 ), and is about 300 seconds, for example, when it is long (t f3 ). The time until the second fuse 323b is blown is determined in consideration of the heat resistance of the housing 352 included in the circuit component 321 and the first base 350. Further, the temperature T F [° C.] at which the second fuse 323b is melted is determined in consideration of the heat resistance of the circuit component 321 included in the power supply device 320 and the housing 352 included in the first base 350.
　本実施の形態では、第２ヒューズ３２３ｂは、バリスタ３２３ｄと接着部材３２３ｅで接着されるものとした。これに対し、第２ヒューズ３２３ｂは、バリスタ３２３ｄの温度が検知できるようにバリスタ３２３ｄに近接して配置するものとしても良い。また、第２ヒューズ３２３ｂは、接着部材３２３ｅを用いずに、バリスタ３２３ｄと接触して設けられるものとしても良い。 In the present embodiment, the second fuse 323b is bonded with the varistor 323d and the bonding member 323e. On the other hand, the second fuse 323b may be disposed close to the varistor 323d so that the temperature of the varistor 323d can be detected. The second fuse 323b may be provided in contact with the varistor 323d without using the adhesive member 323e.
　また、本実施の形態では、第２ヒューズ３２３ｂはバリスタ３２３ｄの温度を検知する。これに対し、第２ヒューズ３２３ｂは、回路部品３２１のうちバリスタ３２３ｄ以外の発熱する部品の温度を検知するものとしても良い。この場合、第２ヒューズ３２３ｂは検知対象の回路部品３２１に接触して配置することが好ましい。 In the present embodiment, the second fuse 323b detects the temperature of the varistor 323d. On the other hand, the second fuse 323b may detect the temperature of a component that generates heat other than the varistor 323d in the circuit component 321. In this case, the second fuse 323b is preferably arranged in contact with the circuit component 321 to be detected.
　また、本実施の形態では第２ヒューズ３２３ｂがバリスタ３２３ｄの温度を検知するものとした。これに対し、第１ヒューズ３２３ａがバリスタ３２３ｄの温度を検知するものとしてもよい。また、第１ヒューズ３２３ａおよび第２ヒューズ３２３ｂが共にバリスタ３２３ｄの温度を検知するものとしてもよい。 In this embodiment, the second fuse 323b detects the temperature of the varistor 323d. On the other hand, the first fuse 323a may detect the temperature of the varistor 323d. Further, both the first fuse 323a and the second fuse 323b may detect the temperature of the varistor 323d.
　また、ダミースタータ１２０が正しく取り付けられた照明装置１０においても、外部から過大な電流が流入した場合に、第１ヒューズ３２３ａまたは第２ヒューズ３２３ｂを溶断して、回路を開放させることが出来る。従って、照明装置１０においても高温から電源装置３２０または発光部３１０を保護することが可能になる。 Also, in the lighting device 10 to which the dummy starter 120 is correctly attached, when an excessive current flows from the outside, the circuit can be opened by blowing the first fuse 323a or the second fuse 323b. Accordingly, the lighting device 10 can also protect the power supply device 320 or the light emitting unit 310 from high temperatures.
