Description
本発明は発光ダイオード（ＬＥＤ）照明装置に係り、さらに詳しくは、放熱性が良好になることから、高い電力を必要とするＬＥＤ照明装置に適用可能なＬＥＤ照明装置に関する。 The present invention relates to a light-emitting diode (LED) illumination device, and more particularly to an LED illumination device applicable to an LED illumination device that requires high power because heat dissipation becomes good.
近年、高速道路、市街地の主な道路、商業地区道路、住宅地区道路、公園などの外部照明灯またはデパート、工場、商業建物などの内部照明灯のために、百熱灯やハロゲン灯などに比べて消費電力が少なく、エネルギー効率が高く、長時間の寿命が保証されるＬＥＤ照明装置が次第に増えつつある。 In recent years, external lighting or highway, main roads in urban areas, commercial district roads, residential district roads, parks, etc. LED lighting devices that consume less power, have high energy efficiency, and guarantee a long lifetime are gradually increasing.
このようなＬＥＤ照明装置は、高い電力を必要とする上記の外部照明灯または内部照明灯として設けられるとき、高熱が発生するために寿命が短縮するという問題がある。従来は、単に放熱板のみを用いてＬＥＤの熱を放熱していたため、ＬＥＤの寿命を期待以上のレベルまで延ばすのには限界があった。 When such an LED illumination device is provided as the above-described external illumination lamp or internal illumination lamp that requires high power, there is a problem in that the lifetime is shortened because high heat is generated. Conventionally, since the heat of the LED is radiated using only a heat radiating plate, there is a limit in extending the life of the LED to a level beyond expectation.
例えば、特許文献１には、外部に設けられる灯器具のソケットと電気的に接続されるバー状の第１回路基板に長さに沿って配列されて光を照射する複数の第１ＬＥＤと、外周縁に第１ＬＥＤが配列された第１回路基板を固定するための面を提供し、内部には開口された左右両端を介して外部と連絡される岐路が形成された管状の金属体と、を備え、第１回路基板は金属体の外周縁に沿って多数配列されることにより、いかなる角度からも第１ＬＥＤが光を照射し、金属体には第１ＬＥＤが配列された第１回路基板を覆って保護するための弧状の第１カバーが設けられ、金属体は、開口された一方の端が、ソケットに係合されて電気的に接続される端子を有する中空状のベースの下面に形成される連絡孔を介して岐路がベースの内部と連絡するように固設されて第１回路基板を固定するための面を提供し、第１回路基板は、ベースの端子と電気的に接続されて第１ＬＥＤにソケットからの電源を供給し、ベースの側面には、ベースの内部を外部と連絡するための第１通孔が形成されて金属体の岐路が金属体の開口された一方の端、連絡孔、ベースの内部及び第１通孔を経て外部と連絡し、第１ＬＥＤの発光により発生する熱が第１回路基板を経て金属体に伝わると、金属体の開口された他方の端を介して岐路に空気が流入して金属体の開口された一方の端、連絡孔、ベースの内部及び第１通孔を経て外部に抜け出る気流が形成され、金属体に伝導される第１ＬＥＤの熱はその気流に放出されて冷却されることを特徴とするＬＥＤ照明装置が開示されている。 For example, Patent Document 1 discloses a plurality of first LEDs that are arranged along the length of a bar-shaped first circuit board that is electrically connected to a socket of a lighting fixture provided outside, and that emit light. A tubular metal body that provides a surface for fixing the first circuit board on which the first LEDs are arranged on the periphery, and in which a branch is formed that communicates with the outside through the left and right ends opened; A plurality of first circuit boards are arranged along the outer peripheral edge of the metal body, so that the first LED emits light from any angle, and the metal body covers the first circuit board on which the first LEDs are arranged. An arc-shaped first cover is provided to protect the metal body, and the metal body is formed on the lower surface of the hollow base having one terminal opened and electrically connected to the socket. The crossroads communicate with the interior of the base through the connecting hole The first circuit board is electrically connected to a terminal of the base to supply power from the socket to the first LED, and is fixed to the side surface of the base. The first through hole for connecting the inside of the base to the outside is formed, and the branch of the metal body is connected to the outside through the one end where the metal body is opened, the connecting hole, the inside of the base and the first through hole. When the heat generated by the light emission of the first LED is transmitted to the metal body through the first circuit board, air flows into the branch via the other end of the metal body and the metal body is opened. The LED is characterized in that an airflow is formed that escapes to the outside through the end, the communication hole, the inside of the base, and the first through hole, and the heat of the first LED conducted to the metal body is released into the airflow and cooled. An illumination device is disclosed.
しかし、特許文献１に記載の技術は、ＬＥＤ照明からの熱が金属体の岐路を介して下から上に排出されるため、岐路を通過する空気が限定されており、電力が５０ｗを超える場合に放熱効果が低下することがあった。また、特許文献１に記載の技術は、ＬＥＤを１枚の放熱板で支持するため、メンテナンスに限界があった。 However, in the technique described in Patent Document 1, since heat from the LED lighting is discharged from the bottom to the top through the metal crossing, the air passing through the crossing is limited and the power exceeds 50 w. In some cases, the heat dissipation effect was reduced. In addition, the technique described in Patent Document 1 has a limited maintenance because the LED is supported by a single heat sink.
そこで、本発明は、上記問題に鑑みてなされたものであり、本発明の目的とするところは、放熱性が良好になることから、高い電力を必要とするＬＥＤ照明装置に適用可能なＬＥＤ照明装置を提供することである。 Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide LED lighting applicable to an LED lighting device that requires high power because heat dissipation becomes good.

Is done.
放熱カバー４７０は、長手方向に垂直な断面が弧状を呈し、第３放熱板４５０の第１回路基板４１０が載置された側である上部に外嵌されることにより、第３放熱板４５０に載置された第１回路基板４１０を保護する。 The heat radiating cover 470 has an arc-shaped cross section perpendicular to the longitudinal direction, and is externally fitted to the upper part of the third heat radiating plate 450 on which the first circuit board 410 is placed. The mounted first circuit board 410 is protected.
第３放熱板４５０は、放熱カバー４７０が左右両端に嵌設されるため、左右両端に長手方向に沿ってカバー溝４７１が形成されることが好ましい。 In the third heat radiating plate 450, since the heat radiating cover 470 is fitted at both left and right ends, it is preferable that cover grooves 471 are formed along the longitudinal direction at both left and right ends.
このように、本発明に係る照明部材４００は、図７に示すように、第１嵌合溝２３０及び第２嵌合溝３３０によって第１放熱板２００と第２放熱板３００とが互いに所定の距離を隔ててそれぞれ係合され、照明部材４００同士の間に空気通路Ｚが形成される。このため、空気通路Ｚを介して外部から流入する気流により、照明部材４００からの熱が第２放熱板３００の第１熱排出孔３１０に排出されて冷却されるので、放熱性に優れた高い電力を必要とするＬＥＤ照明装置に適用可能である。また、照明部材４００及び安定器が脱着自在にそれぞれ別々に形成されることにより、簡単にメンテナンスを行うことができる。 Thus, as shown in FIG. 7, the lighting member 400 according to the present invention is configured such that the first heat sink 200 and the second heat sink 300 are predetermined to each other by the first fitting groove 230 and the second fitting groove 330. An air passage Z is formed between the illumination members 400 by being engaged with each other at a distance. For this reason, since the heat from the illumination member 400 is discharged to the first heat discharge hole 310 of the second heat radiating plate 300 by the airflow flowing from the outside through the air passage Z, the heat dissipation is high. It can be applied to an LED lighting device that requires electric power. Further, since the illumination member 400 and the ballast are separately formed so as to be detachable, maintenance can be easily performed.
