Description

この発明は、発光ダイオード素子を用いる照明装置に関する。   The present invention relates to a lighting device using a light emitting diode element.

放熱部に複雑なダイカスト構造の放熱フィンを使用することなしに放熱効果を高めると共に機械的強度を高めたＬＥＤ（発光ダイオード）電球を提供するために、ＬＥＤ素子が取付けられたＬＥＤモジュールと、ＬＥＤモジュールが固定されＬＥＤモジュールで発生する熱を外部に伝達する放熱プレートと、放熱プレートが載置され内部に電源基板が収容された金属製のカバー部材と、が備えられ、放熱プレートは縁部が形成され、縁部の外面とカバー部材の段部の内面は密着する構成としたＬＥＤ電球が提案されている（例えば、特許文献１参照）。   In order to provide an LED (light-emitting diode) bulb having an increased heat dissipation effect and increased mechanical strength without using a complex die-casting heat dissipation fin in the heat dissipation portion, an LED module to which an LED element is attached, and an LED The module includes a heat radiating plate that transfers heat generated by the LED module to the outside, and a metal cover member on which the heat radiating plate is placed and that houses the power supply board. There has been proposed an LED bulb that is formed and has a configuration in which an outer surface of an edge portion and an inner surface of a step portion of a cover member are in close contact with each other (see, for example, Patent Document 1).

また、ＬＥＤ電球に用いられている連結部材は合成樹脂であるので、外郭部材と口金とを電気的に絶縁しているが、外郭部材内の点灯回路が発火すると、連結部材が熱で溶融などして変形してしまい、場合によっては連結体自体も発火してしまうという課題があった。その課題を解決するために、電源の供給を受けて機能する熱源からの発熱を放熱する放熱部等の導電部材と、熱源に電源を供給する外部電源に接続する電源接続部とを連結する連結体であって、連結体は、導電部材と電源接続部を電気的に絶縁するために電気的絶縁性を有し、さらに熱源からの熱による変形を防止するために耐熱性を有することを特徴とする照明装置が提案されている（例えば、特許文献２参照）。   Further, since the connecting member used in the LED bulb is a synthetic resin, the outer member and the base are electrically insulated, but when the lighting circuit in the outer member ignites, the connecting member is melted by heat, etc. As a result, there is a problem that the connecting body itself is ignited. In order to solve the problem, a connection that connects a conductive member such as a heat radiating unit that dissipates heat generated from a heat source that functions by receiving power supply, and a power connection unit that connects to an external power source that supplies power to the heat source. The coupling body is electrically insulative to electrically insulate the conductive member and the power source connection portion, and further has heat resistance to prevent deformation due to heat from a heat source. A lighting device is proposed (for example, see Patent Document 2).

特許文献１及び特許文献２に記載されているように、ＬＥＤ電球のように発光ダイオード素子を利用し、小形で従来の白熱電球と同様の形をした照明装置においては、発光ダイオード素子の発熱により発光ダイオードの寿命が短くなるという課題がある。そのため、現在ほぼ全てのＬＥＤ電球において放熱体が設けられている。そして、放熱体がより効果的に熱を放熱させるように、放熱体、発光ダイオード素子及び点灯回路基板の配置が検討されている。   As described in Patent Document 1 and Patent Document 2, in a lighting device that uses a light emitting diode element like an LED bulb and has a small shape similar to that of a conventional incandescent bulb, the light emitting diode element generates heat. There exists a subject that the lifetime of a light emitting diode becomes short. Therefore, a radiator is provided in almost all LED bulbs at present. And arrangement | positioning of a heat radiator, a light emitting diode element, and a lighting circuit board is examined so that a heat radiator may thermally radiate heat more effectively.

従って、従来の白熱電球のようなガラスの熱加工やカソードの封止といった熟練を要する生産工程は存在しないものの、ＬＥＤ電球の部品点数は白熱電球より多く、工程も複雑である。   Therefore, although there is no production process that requires skill such as thermal processing of glass and sealing of the cathode as in the conventional incandescent bulb, the number of parts of the LED bulb is larger than that of the incandescent bulb and the process is complicated.

図１４は従来の照明装置４００の分解斜視図である。従来の照明装置４００は、図１４に示すように、以下に示す部品で構成されている。
（１）透光カバー４０１；
（２）複数個の固定ネジ４０２；
（３）発光ダイオード素子を実装した発光ダイオード基板４０３；
（４）発光ダイオード素子を冷却する放熱体４０４；

（６）発光ダイオード素子の発光を制御する点灯回路基板４０６；
（７）口金側ハウジング４０７；
（８）口金４０８。 FIG. 14 is an exploded perspective view of a conventional lighting device 400. As shown in FIG. 14, the conventional lighting device 400 includes the following components.
(1) Translucent cover 401;
(2) a plurality of fixing screws 402;
(3) a light emitting diode substrate 403 on which a light emitting diode element is mounted;
(4) a radiator 404 for cooling the light emitting diode element;
(5) a housing 405 for housing the lighting circuit board 406;
(6) a lighting circuit board 406 for controlling light emission of the light emitting diode element;
(7) base housing 407;
(8) Base 408.

このような部品で構成される照明装置４００は、通常発光ダイオード基板４０３、放熱体４０４、点灯回路基板４０６及び点灯回路基板４０６を収納するハウジング４０５が、複数の固定ネジ４０２で固定されている。また、このときのこれら部品（発光ダイオード基板４０３、放熱体４０４、点灯回路基板４０６及び点灯回路基板４０６を収納するハウジング４０５）の位置合わせは、複数の固定ネジ４０２とネジ穴（図示せず）を合致させ、固定ネジ４０２を挿入することによって行う。   In the illuminating device 400 composed of such components, a light emitting diode substrate 403, a radiator 404, a lighting circuit substrate 406, and a housing 405 that houses the lighting circuit substrate 406 are fixed with a plurality of fixing screws 402. At this time, these components (the light emitting diode substrate 403, the radiator 404, the lighting circuit substrate 406, and the housing 405 for housing the lighting circuit substrate 406) are aligned with a plurality of fixing screws 402 and screw holes (not shown). And the fixing screw 402 is inserted.
