Description

Translated fromJapanese

この発明は、LED素子を実装した基板と照明装置筐体の取り付けに関して放熱効果を高めるとともに、取り付けを容易にしたLED照明装置に関するものである。  The present invention relates to an LED illuminating device that enhances the heat dissipation effect and facilitates the attachment with respect to the attachment of the substrate on which the LED element is mounted and the luminaire housing.

LED素子を用いた照明装置において、一般に、放電ランプや白熱灯などの一般照明装置と同等の光量を確保するために、複数のLED素子を集合させて使用するとともに、LED素子に流す電流を大きくして1個あたりの光量を増加させる必要がある。  In an illumination device using LED elements, in general, in order to secure the same amount of light as that of a general illumination device such as a discharge lamp or an incandescent lamp, a plurality of LED elements are used together, and a current flowing through the LED elements is increased. Therefore, it is necessary to increase the amount of light per piece.

このとき、LED素子より発生する熱は、LED素子の数や電流の増加につれて大きくなり、半導体であるLED素子の寿命特性や発光効率が悪化すると共に、LED素子周辺に充填した樹脂も劣化し、照明用光源として必要とされる光量を確保しにくくなる。  At this time, the heat generated from the LED elements increases as the number of LED elements and current increase, and the life characteristics and light emission efficiency of the LED elements that are semiconductors deteriorate, and the resin filled around the LED elements also deteriorates. It becomes difficult to secure the amount of light required as a light source for illumination.

このため、LEDを実装した基板の発光面裏側にフィンを設けて表面積を増やす構造、および基板を熱伝導率のより高い部材へ取り付ける構造により、放熱効果を高めたLED照明装置が提案されている。  For this reason, an LED lighting device with improved heat dissipation has been proposed by a structure in which fins are provided on the back side of the light emitting surface of the substrate on which the LED is mounted to increase the surface area and a structure in which the substrate is attached to a member having higher thermal conductivity. .

第1の従来技術として、LED素子がセラミック基板実装され、基板の裏面にフィンを設けて表面積を増大させ、LED素子の発する熱を効率よく外部に放熱している。また、セラミック基板の嵌合凸部は金属部材の嵌合凹部に対して幅寸法が若干大きく設定されている。基板と金属部材を高温雰囲気中に放置すると、金属部材の方がセラミック製の基板に比較して熱膨張率が大きいため、金属部材の嵌合凹部の幅寸法が基板の嵌合凸部の幅寸法よりも大きくなる。そして、この状態で基板の嵌合凸部を金属部材の嵌合凹部内に挿入し、さらに雰囲温度を高温から常温に戻せば、基板並びに金属部材が収縮して嵌合凸部と嵌合凹部とが嵌合して基板1を熱伝導率のより高い金属部材へ固定させるものである(例えば、特許文献1参照)。  As a first conventional technique, an LED element is mounted on a ceramic substrate, fins are provided on the back surface of the substrate to increase the surface area, and heat generated by the LED element is efficiently radiated to the outside. Further, the fitting convex portion of the ceramic substrate is set to have a slightly larger width dimension than the fitting concave portion of the metal member. If the substrate and the metal member are left in a high temperature atmosphere, the metal member has a larger coefficient of thermal expansion than the ceramic substrate, so the width dimension of the fitting recess of the metal member is the width of the fitting protrusion of the substrate. Larger than the dimensions. In this state, if the mating convex part of the board is inserted into the mating concave part of the metal member, and the ambient temperature is returned from the high temperature to the normal temperature, the board and the metal member are contracted to fit the mating convex part. The recess is fitted to fix thesubstrate 1 to a metal member having a higher thermal conductivity (see, for example, Patent Document 1).

第2の従来技術として、LED素子が基板に実装され、基板の下面が放熱固定板の上面に接するようにし、放熱カバーが基板を覆うように設けられ、これらをネジで樹脂ケースに固定し、LED素子の発する熱を効率よく外部に放熱している(例えば、特許文献2参照)。  As a second conventional technique, the LED element is mounted on the substrate, the lower surface of the substrate is in contact with the upper surface of the heat radiation fixing plate, the heat radiation cover is provided so as to cover the substrate, these are fixed to the resin case with screws, The heat generated by the LED elements is efficiently radiated to the outside (see, for example, Patent Document 2).

特開2003−243718号(段落番号0014、図1、段落番号0031、図5)JP 2003-243718 (paragraph number 0014, FIG. 1, paragraph number 0031, FIG. 5)特開2002−299700号(段落番号0015、図5)JP 2002-299700 (paragraph number 0015, FIG. 5)

しかしながら、上記従来のLED照明装置では、基板の裏面に対してフィンが下方へ向けて垂直に設置されているため、これらを他の部材へ取り付ける際には、ネジおよび接着剤での固定、または熱膨張を利用しての固定などが必要であった。  However, in the conventional LED lighting device, since the fins are installed vertically downward with respect to the back surface of the substrate, when these are attached to other members, fixing with screws and an adhesive, or Fixing using thermal expansion was necessary.

また、接着剤や熱膨張を利用した固定では、基板を交換する際などに取り外しが困難なため、メンテナンス性に問題があった。  In addition, fixing using an adhesive or thermal expansion has a problem in maintainability because it is difficult to remove the substrate when replacing it.

この発明は上記のような問題を解決するためになされたものであり、LED素子から発生した熱を効率よく放熱するとともに、照明装置筺体への取り付けが容易なためメンテナンス性の良いLED照明装置を提供することを目的とする。  The present invention has been made to solve the above-described problems, and efficiently dissipates the heat generated from the LED elements, and an LED lighting device with good maintainability because it can be easily attached to the lighting device housing. The purpose is to provide.

この発明に係るLED照明装置は、反射材が設けられた凹部を前面に有する基板と、前記凹部の底面に実装されたLED素子と、前記基板の裏側に同心円状に形成された複数のフィンと、該複数のフィンのうち、最も外側のフィンの外側面に螺旋状に形成され該フィンの一部をなす係止部と、該係止部が嵌合される螺旋状に形成された溝部を有する照明装置筐体と、を備えたものである。An LED lighting device according to the present invention includes a substrate having a concave portion provided with a reflective material on the front surface, an LED element mounted on the bottom surface of the concave portion,and a plurality of finsformed concentrically on the back side of the substrate. Alocking portion formed spirally on the outer surface of the outermost fin of theplurality of fins and forming a part of the fin; and a spirally formed groove portion into which the locking portion is fitted. And a lighting device casing .

以上のように、この発明によれば、基板の裏側に同心円状に形成された複数のフィンと、該複数のフィンのうち、最も外側のフィンの外側面に螺旋状に形成され該フィンの一部をなす係止部と、該係止部が嵌合される螺旋状に形成された溝部を有する照明装置筐体と、を備えたので、熱伝導率のより高い照明装置筐体との接触面積が大きくなり、LED素子より発生する熱を効率よく外部へ放熱し、LED素子の寿命特性や発光効率の悪化を防ぐと共に、LED素子周辺に充填した樹脂の劣化も防ぐことにより、信頼性を高くすることができ、また、基板に形成したフィンの一部を利用して、照明装置筐体への取り付けが可能であり、取り付けが容易でメンテナンス性を良くすることができる。

And a lighting device housing having a spirally formed groove portion into which the locking portion is fitted . Therefore, contact with the lighting device housing having higher thermal conductivity is provided. Reliability increases by increasing the area, efficiently dissipating heat generated from the LED element to the outside, preventing deterioration of the life characteristics and light emission efficiency of the LED element, and preventing deterioration of the resin filled around the LED element. In addition, it is possible to attach to the lighting device housing by utilizing a part of the fin formed on the substrate, and the attachment is easy and the maintainability can be improved.

次に、基板1と照明装置筐体5の取り付けを説明する。
図3(a)の場合は、基板1の両外側のフィン1aの一方の端部の外側面に突設した係止部1bを照明装置筐体5の溝部5aの一方の被係止部5bに合わせ、また、基板1の他方の端部の内側面に突設した係止部1dを照明装置筐体5の溝部5aの他方の被係止部5dに合わせて、基板1を照明装置筐体5の横方向から挿入して嵌合させる。このとき、基板1の係止部1b、1dが、照明装置筐体5の被係止部5b、5dに各々係止されて、基板1と照明装置筐体5を固定する。
Next, attachment of the board |substrate 1 and the illuminating device housing |casing 5 is demonstrated.
In the case of FIG. 3A, the lockingportion 1 b protruding from the outer surface of one end of thefin 1 a on both outer sides of thesubstrate 1 is used as one lockedportion 5 b of thegroove portion 5 a of thelighting device housing 5. In addition, the locking portion 1d protruding from the inner surface of the other end of thesubstrate 1 is aligned with the other lockedportion 5d of thegroove portion 5a of thelighting device housing 5, so that thesubstrate 1 is mounted on the lighting device housing. Thebody 5 is inserted from the lateral direction and fitted. At this time, the lockingportions 1 b and 1 d of thesubstrate 1 are locked to the lockedportions 5 b and 5 d of thelighting device housing 5 to fix thesubstrate 1 and thelighting device housing 5.
