Description

本考案は照明器具の放熱装置の改良に関し、特に照明効率を高め、消費電量を低くする機能を有する発光ダイオード照明器具の放熱装置に関する。本考案は、照明器具周辺に排気空間を設置し、排気空間の項上部に排気用ファンが設置されて持続的に排気を行ない、発光ダイオード照明器具のプリント回路板の背面に複数の導熱性パーツが設置されて、排気空間内の照明器具周辺にまで伸びている。したがって、発光ダイオード照明器具によって生じる高熱が速やかに照明器具の全体の周辺に伝わり、放熱面積を拡大する効果がある。同時に、排気空間内で放熱された熱気もまた、速やかに排気用ファンによって外に排出されるので、速やかに放熱し、発光ダイオード照明器具の使用寿命の延長することを特徴とする。 The present invention relates to an improvement of a heat radiating device for a lighting fixture, and more particularly to a heat radiating device for a light emitting diode lighting fixture having a function of increasing illumination efficiency and reducing power consumption. The present invention installs an exhaust space around the lighting fixture, and an exhaust fan is installed at the upper part of the exhaust space for continuous exhaust, and a plurality of heat conductive parts on the back of the printed circuit board of the LED lighting fixture Is installed and extends around the lighting fixtures in the exhaust space. Therefore, high heat generated by the light-emitting diode illuminating device is quickly transmitted to the entire periphery of the illuminating device, and there is an effect of expanding the heat radiation area. At the same time, since the hot air radiated in the exhaust space is also quickly discharged outside by the exhaust fan, the heat is quickly radiated to extend the service life of the light-emitting diode illuminator.

高照明効率及び低消費電量の照明器具は現代のニーズである。照明器具において発光ダイオード（ＬＥＤ）照明器具は今やごく一般に普及しており、今後その傾向はますます高まることは間違いない。また、発光ダイオードは発光する時に同時に大量の熱を発するため、効果的にその熱を発散させなければ、発光ダイオードチップが急速に老化し、焼けて破損することもある。 There is a modern need for luminaires with high lighting efficiency and low power consumption. Light emitting diode (LED) lighting fixtures are now very popular in lighting fixtures, and there is no doubt that this trend will increase in the future. Further, since the light emitting diode emits a large amount of heat at the same time when it emits light, unless the heat is effectively dissipated, the light emitting diode chip may be rapidly aged, burned and damaged.

上記の問題を解決するため、放熱金属を追加する方式で放熱の目的を果す技術が提供されている。この技術は、発光ダイオード照明器具に固定されたプリント回路の背面に、貼り付ける形態でひれ状のパーツを設置した放熱体を利用するもので、この放熱体のひれ状のパーツの表面が放熱面積を拡大することによって、発光ダイオード照明器具によって発生する大量の熱が、放熱体に伝えられて、放熱速度を高める効果を持たせるものである。 In order to solve the above problem, a technique for achieving the purpose of heat dissipation by a method of adding a heat dissipation metal is provided. This technology uses a radiator with fin-shaped parts attached to the back of a printed circuit fixed to a light-emitting diode illuminator. The surface of the fin-shaped parts of this radiator is the heat dissipation area. By enlarging this, a large amount of heat generated by the light-emitting diode illuminating device is transmitted to the heat radiating body, and has an effect of increasing the heat radiation speed.

上記の、単一放熱体を発光ダイオード照明器具の背面に貼り付けることにより、放熱効率を高める方式は、小さいパワーの発光ダイオードに対しては、確かにその放熱効果が認められる。しかしながら、現在一般に普及している大きいパワーの発光ダイオードに対しては、その通過する電流がすでに従来の小さいパワーの発光ダイオードよりはるかに大きいため、発生する熱もそれに伴って大幅にアップしている。故に、単純に、上述の技術による放熱体による放熱方式及びその放熱能力は、現在のニーズには対応できず、よりよい放熱効果が得られないという問題がある。 The above-described method for enhancing the heat dissipation efficiency by attaching the single heat dissipator to the back surface of the light-emitting diode illuminating device certainly has a heat-dissipating effect for a light-emitting diode with a small power. However, for the high power light emitting diodes that are currently in widespread use, the current passing therethrough is much larger than that of the conventional low power light emitting diodes, so the generated heat is also greatly increased accordingly. . Therefore, simply, the heat dissipation method using the heat dissipating body and the heat dissipating capacity thereof according to the above-described technology cannot meet the current needs, and there is a problem that a better heat dissipation effect cannot be obtained.

本考案は、放熱面積を拡大することで放熱効果を高め、大きいパワーの発光ダイオードに対応する照明器具の放熱装置を提供することを課題とする。 An object of the present invention is to provide a heat dissipating device for a lighting fixture corresponding to a light-emitting diode having a large power by increasing a heat dissipating area to enhance a heat dissipating effect.

Is installed and extends to the periphery of the pedestal in the exhaust space, the heat dissipation area is expanded, and the high heat generated by the light-emitting diode illuminator is quickly transmitted to the periphery of the entire pedestal, increasing the heat dissipation efficiency In addition, at the same time, the hot air radiated in the exhaust space is also quickly discharged outside by the exhaust fan, so that the heat is quickly radiated.

また、本考案の照明器具の放熱装置は、構造がシンプルで、製作が簡単で便利であり、照明器具の放熱効率を高めることで、照明器具の使用寿命を延長させることが可能である。 Moreover, the heat dissipation device for a lighting fixture of the present invention has a simple structure, is easy to manufacture, and is convenient, and can increase the service life of the lighting fixture by increasing the heat dissipation efficiency of the lighting fixture.

An exhaust fan 90 is provided. The pedestal 10 has a concave shape, has a vent hole 101 at the bottom thereof, and heat dissipating pieces 102 are arranged in the shape of fish fins on the peripheral inner wall. There are a plurality of through-holes 103 in the vicinity of the surrounding bottom. The light-emitting diode luminaire 20 includes a printed circuit board 201 and a plurality of light-emitting diodes 202 fixed to the printed circuit board 201, which are installed at the bottom of the base 10. These light emitting diodes 202 further correspond to the positions of the vent holes 101 of the light emitting diode lighting fixture 20.

放熱体３０は発光ダイオード照明器具２０のプリント回路板２０１の背面に設置され、台座１０内に位置する。さらに、複数の魚のひれ状に放熱片３０１が並んでいて、発光ダイオード照明器具２０によって発生した熱に対して放熱作用を行なう。第一排気用ファン４０は、放熱体３０の一側面に設置されて、放熱体３０が吸収及び発散した熱気に対して排出作用を行ない、放熱効率を高める。電源供給装置５０は台座１０内に設置され、放熱体３０の上方に位置して電源供給作用を行なう。 The radiator 30 is installed on the back surface of the printed circuit board 201 of the light-emitting diode luminaire 20 and is located in the base 10. Further, the heat dissipating pieces 301 are arranged in the shape of a plurality of fish fins, and perform a heat dissipating action on the heat generated by the light emitting diode lighting fixture 20. The first exhaust fan 40 is installed on one side surface of the heat radiating body 30 and performs a discharge action on the hot air absorbed and diffused by the heat radiating body 30 to improve the heat radiation efficiency. The power supply device 50 is installed in the pedestal 10 and is located above the radiator 30 to perform power supply operation.

複数の導熱性パーツ６０は、その吸熱先端がそれぞれ発光ダイオード照明器具２０のプリント回路板２０１背面あるいは放熱体３０底部の近くの位置に貼り付く形で設置されて、発光ダイオード照明器具２０が発生した高熱を速やかに台座１０周辺に伝えて、その放熱片１０２によって速やかに放熱が行なわれる。内カバー７０は、台座１０内の発光ダイオード照明器具２０、放熱体３０、第一排気用ファン４０、電源供給装置５０等の構成部分をカバーして、台座１０周辺との間にちょうど導熱性パーツ６０を収納する第一排気空間Ａ₁を形成する。その第一排気空間Ａ₁は台座１０周辺底部の貫通穴１０３と互いに通じている。外カバー８０は、台座１０上方に取り付けられ、内カバー７０と共に第二排気空間Ａ₂を形成する。この第二排気空間Ａ₂はさらに台座１０と内カバー７０との間の第一排気空間Ａ₁と通じている。第二排気用ファン９０は外カバー８０頂上部に取り付けられて、第二排気空間Ａ₂と通じている。 The plurality of heat conductive parts 60 are installed in such a manner that their heat-absorbing tips stick to the back surface of the printed circuit board 201 of the light-emitting diode lighting device 20 or near the bottom of the radiator 30 to generate the light-emitting diode lighting device 20. High heat is quickly transmitted to the periphery of the pedestal 10, and the heat radiating piece 102 quickly radiates heat. The inner cover 70 covers components such as the light-emitting diode illuminating device 20, the radiator 30, the first exhaust fan 40, and the power supply device 50 in the pedestal 10, and is just a heat conductive part between the periphery of the pedestal 10. A first exhaust space A ₁ for accommodating 60 is formed. The first exhaust space A ₁ communicates with the through hole 103 at the bottom around the base 10. The outer cover 80 is attached above the base 10 and forms a second exhaust space A ₂ together with the inner cover 70. The second exhaust space A ₂ further communicates with the first exhaust space A ₁ between the base 10 and the inner cover 70. Second exhaust fan 90 is attached to the 80 top of the outer cover, in communication with the second exhaust space A _2.

上述の構成により、本考案は以下のように実施する。発光ダイオード照明器具２０のプリント回路板２０１背面には、複数の導熱性パーツ６０の吸熱先端が取り付けられ、これらの導熱性パーツ６０の吸熱先端はまた、台座１０の周辺内壁まで伸びている。発光ダイオード照明器具２０が発生した高熱は、直接速やかに台座１０全体の周辺に伝えられる。同時に、台座１０周辺には複数の魚のひれ状に放熱片１０２が並んでいて、放熱面積を拡大する。そして、放熱片１０２及び導熱性パーツ６０がいずれも第一排気空間Ａ₁内に収納されていて、台座１０周辺に伝えられた高熱もまた、速やかに第一排気空間Ａ₁全体で発散される。また、外カバー８０及び内カバー７０の間に形成された第二排気空間Ａ₂は、第一排気空間Ａ₁と通じている。そして、外カバー８０頂上部に設置された第二排気空間Ａ₂も排気動作を続ける。第一排気空間Ａ₁で発散された熱気は、速やかに第二排気空間Ａ₂から外に排出されて、放熱効率を高めることができる。台座１０周辺底部には複数の貫通穴１０３が設置されていて、第一排気空間Ａ₁に対応する。故に、前述の第二排気用ファン９０は第一排気空間Ａ₁、第二排気空間Ａ₂内の熱気に対して排出動作を行なう時、新鮮な空気が直接これらの貫通穴１０３から第一排気空間Ａ₁に進入する。自然と空気の対流がスムーズになり、台座１０の多くの放熱片１０２が発散して出された熱気は、速やかに排出されて、確実に放熱効果を高めることができる。 With the above-described configuration, the present invention is implemented as follows. The heat absorption tips of the plurality of heat conductive parts 60 are attached to the back surface of the printed circuit board 201 of the light emitting diode lighting device 20, and the heat absorption tips of these heat conductive parts 60 also extend to the peripheral inner wall of the base 10. The high heat generated by the light-emitting diode luminaire 20 is directly and directly transmitted to the periphery of the pedestal 10. At the same time, heat dissipating pieces 102 are arranged in the shape of a plurality of fish fins around the pedestal 10 to expand the heat dissipating area. The heat radiating piece 102 and the heat conductive part 60 are both housed in the first exhaust space A ₁ , and the high heat transmitted to the periphery of the pedestal 10 is also quickly diffused throughout the first exhaust space A _1. . The second exhaust space A ₂ formed between the outer cover 80 and the inner cover 70 communicates with the first exhaust space A ₁ . The second exhaust space A ₂ installed at the top of the outer cover 80 also continues the exhaust operation. The hot air diffused in the first exhaust space A ₁ can be quickly discharged out of the second exhaust space A ₂ , and the heat radiation efficiency can be improved. The pedestal 10 near the bottom have a plurality of through holes 103 is disposed, corresponding to the first exhaust space A _1. Therefore, when the second exhaust fan 90 performs a discharge operation on the hot air in the first exhaust space A ₁ and the second exhaust space A ₂ , fresh air is directly discharged from the through holes 103 to the first exhaust. It enters the space A _1. The convection between air and air becomes smooth, and the hot air emitted by the radiating pieces 102 of the pedestal 10 diverging out is quickly discharged, so that the heat dissipation effect can be improved with certainty.

上述のように、内カバー７０は発光ダイオード照明器具２０、放熱体３０、第一排気用ファン４０、電源供給装置５０等の構成部分をカバーして、台座１０周辺底部の複数の貫通穴１０３もまた第一排気空間Ａ₁及び第二排気空間Ａ₂に対応するので、戸外での本考案の照明器具を運用する場合は、第二排気用ファン９０から浸入した雨水が内カバー７０の外側に沿ってスムーズに下に流れて行き、自然に貫通穴１０３から排出される。したがって、雨に濡れて、内カバー７０内のパーツが損傷することがない。 As described above, the inner cover 70 covers components such as the light-emitting diode illuminating device 20, the radiator 30, the first exhaust fan 40, the power supply device 50, and the like, and the plurality of through-holes 103 around the base 10 are also provided. In addition, since it corresponds to the first exhaust space A ₁ and the second exhaust space A ₂ , rainwater that has entered from the second exhaust fan 90 is placed outside the inner cover 70 when the lighting fixture of the present invention is operated outdoors. It flows smoothly down along and is naturally discharged from the through hole 103. Therefore, the parts in the inner cover 70 are not damaged due to rain.

上述のように、発光ダイオード照明器具２０の背面には放熱体３０及び第一排気用ファン４０が設置されていることにより、発光ダイオード照明器具２０が発生した熱気は、前述の導熱性パーツ６０を介して台座１０周辺に伝えられて大きな面積及び高効率での放熱が行なわれる外、同時に、放熱体３０の複数の放熱片３０１を介して補助的に放熱を行なう。当然、第一排気用ファン４０の送風によって、放熱体３０が発散した熱気は、さらに速やかに発光ダイオード照明器具２０周辺の通気穴１０１から排出されて、放熱効果を高めることができる。 As described above, since the radiator 30 and the first exhaust fan 40 are installed on the back surface of the light-emitting diode luminaire 20, the heat generated by the light-emitting diode luminaire 20 In addition to being transmitted to the periphery of the pedestal 10 to dissipate heat with a large area and high efficiency, at the same time, heat is radiated supplementarily through the plurality of heat dissipating pieces 301 of the heat dissipating body 30. Naturally, the hot air diffused by the heat radiating body 30 due to the ventilation of the first exhaust fan 40 is quickly discharged from the vent hole 101 around the light-emitting diode illuminating device 20, and the heat radiation effect can be enhanced.

したがって、発光ダイオード照明器具２０の放熱効率を高めるために、導熱性パーツ６０の吸熱先端及び放熱先端は、それぞれいずれも発光ダイオード照明器具２０のプリント回路板２０１背面及び台座１０周辺に分布することが望ましい。 Therefore, in order to increase the heat dissipation efficiency of the light-emitting diode illuminating device 20, the heat-absorbing tip and the heat-dissipating tip of the heat conductive part 60 may be distributed around the back surface of the printed circuit board 201 and the base 10 around the light-emitting diode illuminating device 20, respectively. desirable.
