Description

本発明は、ＬＥＤチップを光源として内蔵するＬＥＤランプに関する。   The present invention relates to an LED lamp incorporating an LED chip as a light source.

近時、消費電力の大きい白熱電球に代えて、消費電力の少ないＬＥＤを光源として用いるＬＥＤランプの需要が高まっている。
一般に、この種のＬＥＤランプはＬＥＤチップを実装したモジュール基板を熱伝導性と放熱性に優れたアルミニウムなどの金属性放熱体の一端に固定し、モジュール基板を覆うように透明又は半透明のグローブを放熱体に取付け、放熱体の他端側に口金を取り付け、ＬＥＤチップに電力を供給する点灯回路を放熱体に内蔵し、点灯回路と口金を電気的に接続した構成を備えている。 Recently, there is an increasing demand for LED lamps that use LEDs with low power consumption as light sources instead of incandescent bulbs with high power consumption.
In general, this type of LED lamp is a transparent or translucent globe that covers a module substrate by fixing the module substrate on which the LED chip is mounted to one end of a metal radiator such as aluminum having excellent thermal conductivity and heat dissipation. Is attached to the radiator, a base is attached to the other end of the radiator, a lighting circuit for supplying power to the LED chip is built in the radiator, and the lighting circuit and the base are electrically connected.

ところで、白熱電球の光源であるフィラメントの発する光は周囲に拡散し、周囲を均等に照らすが、ＬＥＤランプの光源として用いられるＬＥＤチップの発する光は高い指向性を有し、前方の狭い領域を強い光で照射するという特性を備えている。
また、白熱電球のフィラメントは点灯時２０００度の高温に達することもあり、フィラメントを覆うグローブの表面が熱せられて、高温になり、これに触ると火傷するおそれがある。
これに対し、ＬＥＤランプの光源であるＬＥＤチップは点灯時の発熱量がフィラメントに比べると極めて低く、点灯時におけるグローブの内部温度を数十度程度に抑えることもできる。 By the way, the light emitted from the filament, which is the light source of the incandescent bulb, diffuses to the surroundings and illuminates the surroundings evenly. However, the light emitted from the LED chip used as the light source of the LED lamp has high directivity and has a narrow area in front. It has the property of irradiating with strong light.
Also, the filament of the incandescent bulb may reach a high temperature of 2000 degrees when it is lit, and the surface of the globe covering the filament is heated to a high temperature, which may cause burns when touched.
On the other hand, the LED chip, which is the light source of the LED lamp, has an extremely low calorific value at the time of lighting as compared with the filament, and can suppress the internal temperature of the globe at the time of lighting to several tens of degrees.

FIG. 1 and FIG. 2 show an LED lamp 10 according to a first embodiment of the present invention. The LED lamp 10 includes a heat sink 11 made of aluminum, a module substrate 13 on which the LED chip 12 is mounted, a dome-shaped globe 14 made of translucent glass or resin, a base 15, and a lighting circuit 16 that supplies power to the LED chip 12. It has.

放熱体１１は逆円錐台形の外観を有し、外周部には表面積を増加して放熱効果を高めるため多数のフィン１１ａが形成されている。放熱体１１の上端面には、モジュール基板１３が固定されている。また放熱体１１の内部には、点灯回路１６が内蔵され、モジュール基板１３と点灯回路１６がリード線１７で接続されている。放熱体１１の下端部には口金１５が装着されている。そして、点灯回路１６と口金１５がリード線で電気的に接続されている。   The radiator 11 has an inverted frustoconical appearance, and a large number of fins 11a are formed on the outer peripheral portion in order to increase the surface area and enhance the heat dissipation effect. A module substrate 13 is fixed to the upper end surface of the radiator 11. Further, a lighting circuit 16 is built in the radiator 11, and the module substrate 13 and the lighting circuit 16 are connected by a lead wire 17. A base 15 is attached to the lower end of the radiator 11. The lighting circuit 16 and the base 15 are electrically connected by lead wires.

放熱体１１の上端面にはリング溝１１ｂが形成されている。このリング溝１１ｂにグローブ１４の下端開口端部が嵌合している。このグローブ１４はモジュール基板１３を覆うように放熱体１１に着脱可能に取り付けられている。そして、グローブ１４の内部にはＬＥＤチップ１２の発する光を乱反射する乱反射物として、多数のアクリル樹脂製ボール１８が装填され、ボール１８によってグローブ１４の内容積の略半分が占められている。ボール１８の材質はＬＥＤランプ１０の点灯時におけるグローブ１４の内部の最高温度でも溶融したり、着火するおそれのないものが選択されている。   A ring groove 11 b is formed on the upper end surface of the radiator 11. The lower end opening end of the globe 14 is fitted in the ring groove 11b. The globe 14 is detachably attached to the radiator 11 so as to cover the module substrate 13. A large number of acrylic resin balls 18 are loaded inside the globe 14 as irregular reflectors that diffusely reflect the light emitted from the LED chip 12, and the balls 18 occupy approximately half of the internal volume of the globe 14.

A nylon ribbon 21 is lightly rolled or compressed and loaded inside the globe 14 of the LED lamp 20. The material of the ribbon 21 is selected so as not to melt or ignite at the maximum temperature in the globe 14.
According to the LED lamp 20 according to the second embodiment, the form of the resin ribbon 21 loaded in the globe 14 expands or contracts due to a change in temperature or humidity in the globe 14 when the LED lamp 20 is turned on or off, or is expanded and compressed. Therefore, every time the LED lamp 20 is turned on, an unpredictable lighting effect occurs.

本発明の第３実施例に係るＬＥＤランプ３０を図４に示す。当該ＬＥＤランプ３０のグローブ１４の内部には、ナイロン製の布片３１が軽く丸めて若しくは圧縮して装填されている。

Inside the globe 14 of the LED lamp 30, a nylon cloth piece 31 is lightly rolled or compressed.
According to the LED lamp 30 according to the third embodiment, the form of the nylon cloth piece 31 loaded in the globe 14 expands and compresses due to a change in temperature or humidity in the globe 14 when the LED lamp 30 is turned on or off. Since it changes regularly, an unpredictable lighting effect occurs every time the LED lamp 30 is turned on.

本発明の第４実施例に係るＬＥＤランプ４０を図５示す。当該ＬＥＤランプ４０のグローブ１４内部には、ナイロン製の糸４１が不規則に軽く巻いた状態で装填されている。
第４実施例に係るＬＥＤランプ４０によれば、グローブ１４に装填した糸巻き４１の形態がグローブ１４内の温度又は湿度の変化によって伸縮したり膨張圧縮して不規則に変化するので、ＬＥＤランプ４０を点灯する度に予測できない照明効果が生じる。 FIG. 5 shows an LED lamp 40 according to a fourth embodiment of the present invention. Inside the globe 14 of the LED lamp 40, a nylon thread 41 is loaded in an irregularly lightly wound state.
According to the LED lamp 40 according to the fourth embodiment, the form of the bobbin 41 loaded in the globe 14 is irregularly changed due to expansion / contraction or expansion / compression due to a change in temperature or humidity in the globe 14. Whenever is turned on, an unpredictable lighting effect occurs.

本発明の第５実施例に係るＬＥＤランプ５０を図６に示す。当該ＬＥＤランプ５０のグローブ１４内部には、発泡スチロールの砕片５１が装填されている。

Inside the globe 14 of the LED lamp 50, styrene foam fragments 51 are loaded.
According to the LED lamp 50 according to the fifth embodiment, the position of the polystyrene foam fragments 51 loaded in the globe 14 varies irregularly depending on the inclination of the globe 14. Further, since the polystyrene foam fragments 51 are light, they float in the globe 14 as the temperature in the globe 14 changes due to the turning on and off of the LED lamp 50. Therefore, it is possible to obtain an illumination effect that cannot be predicted for each way of installing the LED lamp 50 or for each lighting.

なお、上記実施例ではグローブ１４をリング溝１１ｂにはめ込む方式で着脱可能に取り付けたので、乱反射物をユーザーが選択してグローブ１４に装填できる。また、グローブ１４の着脱方法としてグローブ１４と放熱体１１にネジを形成すればより容易にグローブ１４を着脱できる。さらにまた、要すればグローブ１４を接着剤で放熱体１１に固着することも可能である。   In the above-described embodiment, since the globe 14 is detachably attached by fitting it in the ring groove 11b, the user can select an irregular reflection object and load it into the globe 14. Further, as a method of attaching and detaching the globe 14, if the screws are formed on the globe 14 and the heat dissipating body 11, the globe 14 can be attached and detached more easily. Furthermore, if necessary, the globe 14 can be fixed to the radiator 11 with an adhesive.
