Description

本発明は、発光ダイオード（以下、ＬＥＤという）を光源とする照明装置に関する。   The present invention relates to a lighting device using a light emitting diode (hereinafter referred to as LED) as a light source.

２０世紀中には不可能と言われていた青色ＬＥＤの開発は、青色ＬＥＤと、青色の光に励起され黄色に発光する蛍光体とから構成されるシングルチップ方式の白色ＬＥＤ並びに、２色以上のＬＥＤによる混光を利用するマルチチップ方式の白色ＬＥＤの商用化を実現した。   Blue LED development, which was said to be impossible during the 20th century, is a single-chip white LED composed of a blue LED and a phosphor that emits yellow light when excited by blue light, and more than two colors. The commercialization of multi-chip type white LED that utilizes the mixed light of the LED of this type was realized.

最近は、小型、省電力というＬＥＤの特徴から、特に照明装置としてのＬＥＤの使用が急増している。例えば消費電力１Ｗあたりの光束（光源からの光の量）で示す効率が、白色ＬＥＤは最大３０ｌｍ／Ｗまで達し、白熱電球の１５ｌｍ／Ｗ及びハロゲン電球の２０ｌｍ／Ｗを越える優れた効率を発揮する。   Recently, the use of LEDs as lighting devices has been rapidly increasing due to the characteristics of LEDs that are small and power-saving. For example, the efficiency indicated by the luminous flux per 1W of power consumption (the amount of light from the light source) reaches 30 lm / W at maximum for white LEDs, and exhibits excellent efficiency exceeding 15 lm / W for incandescent bulbs and 20 lm / W for halogen bulbs. To do.

上述のようにＬＥＤが照明装置へ使用されることにつれて、様々な技術が提案されている。例えば特許文献１では、複数のＬＥＤ使用に伴う放熱問題を考慮し、複数のＬＥＤが配置されるＬＥＤ配置面に放熱部が接するように配置した電球形の発光ダイオードランプを提案している。   As described above, various technologies have been proposed as LEDs are used in lighting devices. For example, Patent Document 1 proposes a light bulb-type light emitting diode lamp that is arranged so that a heat radiating portion is in contact with an LED arrangement surface on which a plurality of LEDs are arranged in consideration of a heat radiation problem associated with the use of a plurality of LEDs.

また、特許文献２では、光源であるＬＥＤと、該ＬＥＤが配設された基板を支持する支持部およびＬＥＤからの光を反射する載頭錐形の反射部を有する金属体とを備え、ＬＥＤの点灯によって発生した熱を、基板から金属体に伝熱し、さらに照明装置本体に伝熱して放熱する照明装置を提案している。   Moreover, in patent document 2, it is equipped with LED which is a light source, and the metal body which has the support part which supports the board | substrate with which this LED was arrange | positioned, and the mounting cone-shaped reflection part which reflects the light from LED, LED Has proposed a lighting device that transfers heat generated by lighting from a substrate to a metal body, and further transfers heat to the lighting device body to dissipate heat.

従来の白熱電球、蛍光灯等のランプにおいては、夫々の機能に応じてグローブの中を不活性ガス又は水銀ガスで充填させていた。そのため、グローブ、フィラメント又は口金を夫々取り外すことが可能に構成することが出来ず、グローブが割れた場合、フィラメントが切れた場合等において、グローブ又はフィラメントのみを取り替えることが出来ず、いずれの場合も白熱電球、蛍光灯全体を取り替える必要があった。   In conventional lamps such as incandescent bulbs and fluorescent lamps, the globe is filled with an inert gas or mercury gas according to the respective functions. Therefore, the glove, filament or base cannot be configured to be removable, and the glove or filament alone cannot be replaced when the glove breaks or the filament breaks. It was necessary to replace the entire incandescent bulb and fluorescent lamp.

一方、上述のようにＬＥＤが照明の光源として使用された場合は、グローブの中をガスで充填させる必要がなくなっており、このような状況の中で、従来のように、グローブのみが割れた場合も、光源が切れた場合も、電球全体を取り替えるのは、資源の浪費にほかならない。
特開２００５−２８６２６７号公報 特開２００５−２５１６３７号公報 On the other hand, when the LED is used as a light source for illumination as described above, it is not necessary to fill the inside of the glove with gas. Whether or not the light source is burned out, replacing the entire bulb is a waste of resources.

しかしながら、特許文献１の発光ダイオードランプ及び特許文献２の照明装置はいずれも、グローブ、光源又は放熱部別の取り外しを考慮していない構成であり、グローブ、光源又は放熱部の何れかに損傷が発生した場合、依然として発光ダイオードランプ又は照明装置の全体を取り替える必要があった。   However, neither the light-emitting diode lamp of Patent Document 1 nor the illumination device of Patent Document 2 has a configuration that does not consider removal of a globe, a light source, or a heat dissipation unit, and any of the globe, the light source, or the heat dissipation unit is damaged. If so, it was still necessary to replace the entire light emitting diode lamp or lighting device.

また、特許文献１の発光ダイオードランプ及び特許文献２の照明装置は、放熱に外気を利用する空冷式放熱を採用し、複数のＬＥＤ使用に伴う放熱の問題に対応しているが、何れも空冷式放熱において重要である外気との接触面積の確保について十分に考慮されていないといった問題もある。   In addition, the light emitting diode lamp of Patent Document 1 and the lighting device of Patent Document 2 employ air-cooled heat radiation using outside air for heat radiation, and cope with the problem of heat radiation associated with the use of a plurality of LEDs. There is also a problem that sufficient consideration has not been given to securing the contact area with the outside air, which is important in the heat radiation of the type.

上述のように覆部４、光源部１、放熱部２及び回路部７は、第１螺合機構、第２螺合機構及び第３螺合機構により、夫々着脱可能に取り付けられている。したがって必要に応じて必要な部分のみを取り外し、取替え、メンテナンス等を行うことが可能である。例えば、覆部４が割れた場合は、覆部４を時計方向に回転させることにより、第１螺合機構の螺合を解除して覆部４を基盤１４から分離し、新しい覆部４に取り替えることが可能である。また、光源部１に断線が発生した場合、放熱部２の放熱フィン２１に埃が溜まった場合等には、上述のように覆部４を取り外して保持柱１７を時計方向に回転させることにより、第３螺合機構の螺合を解除して光源部１及び放熱部２を回路部７から分離した後、放熱部２を更に時計方向に回転させることにより、第２螺合機構の螺合を解除して光源部１の保持部１７から放熱部２を分離し、光源部１の取替え及び放熱フィン２１の掃除を行うことが可能である。   As described above, the cover 4, the light source unit 1, the heat radiating unit 2, and the circuit unit 7 are detachably attached by the first screwing mechanism, the second screwing mechanism, and the third screwing mechanism, respectively. Therefore, only necessary portions can be removed, replaced, maintained, etc., as necessary. For example, when the cover part 4 is cracked, the cover part 4 is rotated clockwise to release the screwing of the first screwing mechanism to separate the cover part 4 from the base 14, so that a new cover part 4 is formed. It is possible to replace it. Further, when the light source unit 1 is disconnected, or when dust accumulates on the radiating fins 21 of the radiating unit 2, the cover 4 is removed as described above, and the holding column 17 is rotated clockwise. After the screwing of the third screwing mechanism is released and the light source unit 1 and the heat radiating unit 2 are separated from the circuit unit 7, the heat radiation unit 2 is further rotated in the clockwise direction, thereby screwing the second screwing mechanism. Is released, the heat radiating part 2 is separated from the holding part 17 of the light source part 1, and the light source part 1 can be replaced and the radiating fins 21 can be cleaned.

また、回路部７の回路収容部６内部に収容されている駆動回路部３に断線が発生した場合等には、回路収容部６の縮径部６Ｂを時計方向に回転させて第４螺合機構の螺合を解除し、縮径部６Ｂ及び口金部５を取り外した後、掛止部材６４から駆動回路部３を分離し、駆動回路部３のみを取り替えることも可能である。よって、回路部７全体を保持柱１７から取り外すことなく、駆動回路部３のみを口金部５側から取り替えられるので、簡便であり、また、回路収容部６をそのまま利用することができる。   In addition, when a disconnection occurs in the drive circuit unit 3 housed in the circuit housing unit 6 of the circuit unit 7, the reduced diameter portion 6B of the circuit housing unit 6 is rotated clockwise to perform the fourth screwing. It is also possible to separate the drive circuit unit 3 from the latch member 64 and replace only the drive circuit unit 3 after releasing the screwing of the mechanism and removing the reduced diameter portion 6B and the cap portion 5. Therefore, since only the drive circuit part 3 can be replaced from the base part 5 side without removing the entire circuit part 7 from the holding column 17, it is simple and the circuit housing part 6 can be used as it is.

上述の例においては、各螺合機構は時計方向へ回転させることによって解除される場合を例として説明したが、これに限るものでなく、反時計方向へ回転させた場合、各螺合機構の螺合が解除されるように構成しても良い。   In the above-described example, the case where each screwing mechanism is released by rotating clockwise is described as an example. However, the present invention is not limited to this, and when the screwing mechanism is rotated counterclockwise, You may comprise so that screwing may be cancelled | released.

また、上述の例においては、第１螺合機構においては覆部４を、第２螺合機構においては保持部１７を、第３螺合機構においては放熱部２を、第４螺合機構においては縮径部６Ｂを夫々同一方向に回転させることにより、各螺合機構が解除される場合を例として説明したが、これに限るものでない。例えば、少なくとも一つの螺合機構と他の螺合機構との解除のための回転方向が異なるように構成しても良い。この場合、解除を意図しなかった別の螺合機構の解除を防止することが可能となる。   In the above-described example, the cover 4 is provided in the first screwing mechanism, the holding part 17 is provided in the second screwing mechanism, the heat dissipating part 2 is provided in the third screwing mechanism, and the fourth screwing mechanism. In the above description, an example has been described in which each screwing mechanism is released by rotating the reduced diameter portion 6B in the same direction, but the present invention is not limited thereto. For example, the rotational directions for releasing at least one screwing mechanism and other screwing mechanisms may be different. In this case, it is possible to prevent the release of another screwing mechanism that is not intended to be released.

本発明の実施の形態３に係る照明装置の放熱部２は、保持柱１７と螺合するためのメネジ２２１が内側に設けられた円筒状の内側保持筒２２と、内側保持筒２２に固定されている多孔質の放熱ブロック２１Ｂとを備えている。放熱ブロック２１Ｂは基盤１４の直径と略等しい直径の円筒状をなしており、中心部には内側保持筒２２の外径と略等しく、内側保持筒２２が貫通可能な内径の貫通孔が設けられている。該貫通孔内に内側保持筒２２が挿入された状態で、内側保持筒２２の外周面に放熱ブロック２１Ｂの前記貫通孔の内面が固定されている。内側保持筒２２と、放熱ブロック２１Ｂとは何れもアルミニウム製である。   The heat dissipating part 2 of the lighting device according to Embodiment 3 of the present invention is fixed to a cylindrical inner holding cylinder 22 provided with a female screw 221 for screwing with the holding column 17 and an inner holding cylinder 22. And a porous heat dissipation block 21B. The heat dissipating block 21B has a cylindrical shape having a diameter substantially equal to the diameter of the base 14, and is provided with a through hole having an inner diameter through which the inner holding cylinder 22 can penetrate, in the center. ing. With the inner holding cylinder 22 inserted in the through hole, the inner surface of the through hole of the heat dissipation block 21B is fixed to the outer peripheral surface of the inner holding cylinder 22.

いわゆる異形粉又は球体粉の形状を有する金属粉の成形体（金属粉体）をその金属の溶融点前後の温度にて加熱処理した場合、金属粉の粒子表面にのみ液相が形成されるので金属粒子同士の接触部分にはいわゆるネッキングが形成されるが、接触部分の残余部分はいわゆる金属粒子間の空隙が形成される。従って、前記加熱処理が施された金属粉体（焼結金属）は、前記ネッキングによって耐久性（強度）が向上すると共に、前記空隙からなる無数の開気孔又は閉気孔を含む多孔質になる。このような多孔質の焼結金属からなる放熱ブロック２１Ｂは、放熱面積を十分に確保することが可能となる。   When a metal powder shaped body (metal powder) having the shape of a so-called deformed powder or spherical powder is heated at a temperature around the melting point of the metal, a liquid phase is formed only on the surface of the metal powder particles. A so-called necking is formed at the contact portion between the metal particles, but a void between the metal particles is formed at the remaining portion of the contact portion. Accordingly, the metal powder (sintered metal) subjected to the heat treatment is improved in durability (strength) by the necking and becomes porous including innumerable open pores or closed pores composed of the voids. The heat dissipating block 21B made of such porous sintered metal can secure a sufficient heat dissipating area.

Thereafter, the heat generated from the LED module 13 is released into the outside air through the outer surface of the heat dissipation block 21B and the inner surface of the internal open hole. The heat radiation part 2 is detachably screwed to the holding column 17 by the second screwing mechanism similar to that of the first embodiment. When removing the heat dissipating part 2, after removing the light source part 1 and the heat dissipating part 2 as described in the first embodiment, the heat dissipating part 2 is rotated in the clockwise direction, thereby screwing the second screw structure.
