以下に、本発明の実施の形態を図面で説明するが、本発明は、これに限定されるものではない。本発明は、全方向に傾斜した反射部材の中心部にＬＥＤ光源を有し、該反射部材は反射性能と共に放熱性に優れた放熱部材からなることを特徴とするＬＥＤ光源の反射及び放熱構造である。Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. The present invention provides an LED light source reflecting and radiating structure characterized in that it has an LED light source at the center of a reflecting member inclined in all directions, and the reflecting member is composed of a heat radiating member having excellent heat dissipation as well as reflecting performance. is there.

図１及び図２において、本発明のＬＥＤ光源の反射及び放熱構造１，２は、少なくとも１個のＬＥＤ光源３を中心にその周囲に全方向に傾斜した反射部材４を配置したものからなる。反射部材４の下部には補助放熱部材１１を有するが、この補助放熱部材１１は照度が低い場合は低発熱性であるから、なくてもよい。ここで、図１、図２は、反射部材４は、ＬＥＤ光源３を中心にその周囲に全方向に傾斜した反射部材が示されているが、これは、本発明の一部の例であって、これに限定されるものではなく、後述するように、図１０に示される数多くの実施の形態がある。1 and 2, the LED light source reflection andheat dissipation structures 1 and 2 according to the present invention are formed by disposing a reflectingmember 4 inclined in all directions around at least oneLED light source 3 as a center. The auxiliaryheat radiating member 11 is provided at the lower part of the reflectingmember 4, but this auxiliaryheat radiating member 11 may be omitted because it has low heat generation when the illuminance is low. Here, FIG. 1 and FIG. 2 show the reflectingmember 4 as a reflecting member inclined in all directions around theLED light source 3, but this is an example of a part of the present invention. However, the present invention is not limited to this, and there are many embodiments shown in FIG. 10 as described later.

また、図２、図３において、ＬＥＤ光源３としては、各種のものが用いられ、具体的には、一個のＬＥＤ光源、複数のＬＥＤ光源、面発光のＬＥＤ光源、有機ＬＥＤ光源等が用いられるが、これらのうち、面発光のＬＥＤ光源、有機ＬＥＤ光源が好ましい。複数のＬＥＤ光源３１は、基板上に複数のＬＥＤを搭載したものであり、また面発光のＬＥＤ光源は、絶縁層を介して設けられた２枚の導電層を含む積層体に斜面を設け、この両導電層間にＬＥＤを設けた構造からなる（特開２００２−３２９８９３）。更に有機ＬＥＤ光源３２は、発光層が有機化合物からなる発光ダイオード（ＬＥＤ）を構成しており、有機化合物中に注入された電子と正孔の再結合によって生じた励起子によって発光する、いわゆる有機ＥＬをいう。このようなＬＥＤ光源３の周囲には、すり鉢状の反射部材４が、ＬＥＤ光を反射して照度を向上させるために配置されている。2 and 3, various types ofLED light sources 3 are used. Specifically, one LED light source, a plurality of LED light sources, a surface emitting LED light source, an organic LED light source, and the like are used. However, among these, surface emitting LED light sources and organic LED light sources are preferable. The plurality ofLED light sources 31 are a plurality of LEDs mounted on a substrate, and the surface emitting LED light source is provided with a slope on a laminate including two conductive layers provided via an insulating layer, The structure is such that an LED is provided between both conductive layers (Japanese Patent Laid-Open No. 2002-329893). Further, the organicLED light source 32 constitutes a light emitting diode (LED) whose light emitting layer is made of an organic compound, and emits light by excitons generated by recombination of electrons and holes injected into the organic compound. Refers to EL. Around such anLED light source 3, a mortar-shaped reflectingmember 4 is disposed to reflect the LED light and improve the illuminance.

この反射部材４としては、反射性能に優れたものであれば、特に限定されるものではないが、銀、アルミニウム、ステンレススチール等が挙げられる。これらの中で低コストを考えた場合、アルミニウム、ステンレススチールを用いるのが好ましい。この反射部材４の下面には補助放熱板１１を有している。前述の如く反射部材４の形状は、すり鉢状に設けられ、その中央にＬＥＤ光源３を有するものであるが、反射部材４は、反射性能と放熱性能を有している。更に放熱性を有する反射部材４は、放熱性能を向上させるために、反射部材４の底の裏面に接触して補助放熱部材１１を設けている。具体的には、図２のａ、図３のａに示されるように、補助放熱部材１１ａは、長方形のアルミニウム板が用いられている。これにより反射部材４からの熱が補助放熱部材１１ａに移行し、この補助放熱部材１１ａから熱放散され、放熱効果を促進する。図２のｂ、図３のｃは、設置面積を少なくするなか、放熱効果を増大させるために補助放熱部材１１ｂの両端を立ち上げる（立ち上げ部１１ｃ）ことによって放熱効果が促進される。図３のｂは、更に放熱効果を促進させるために、補助放熱部材１１ｄの両端をヒダ状部１１ｆが設けられている。１１ｇはヒダ状部を形成するための切込部１１ｅである。The reflectingmember 4 is not particularly limited as long as it has excellent reflection performance, and examples thereof include silver, aluminum, and stainless steel. Of these, aluminum and stainless steel are preferably used when considering low cost. An auxiliaryheat radiating plate 11 is provided on the lower surface of the reflectingmember 4. As described above, the shape of thereflection member 4 is provided in a mortar shape and has the LEDlight source 3 in the center thereof. Thereflection member 4 has reflection performance and heat dissipation performance. Furthermore, the reflectingmember 4 having heat dissipation is provided with an auxiliaryheat radiating member 11 in contact with the back surface of the bottom of the reflectingmember 4 in order to improve heat dissipation performance. Specifically, as shown in FIG. 2a and FIG. 3a, the auxiliaryheat radiating member 11a is a rectangular aluminum plate. Thereby, the heat from the reflectingmember 4 is transferred to the auxiliaryheat radiating member 11a, and is dissipated from the auxiliaryheat radiating member 11a to promote the heat radiating effect. In FIG. 2b and FIG. 3c, the heat radiation effect is promoted by raising both ends of the auxiliaryheat radiation member 11b (the risingportion 11c) in order to increase the heat radiation effect while reducing the installation area. In FIG. 3 b, fold-like portions 11 f are provided at both ends of the auxiliaryheat radiating member 11 d in order to further promote the heat radiating effect. Reference numeral 11g denotes acut portion 11e for forming a pleated portion.

一方、反射部材４は、反射部材としての機能を維持しつつ、放熱効果をよりいっそう良好にするために、放熱構造の部分図を示す。図４〜図９において、図４、図５は、ジグザグ型の凹凸部２１からなる。即ち、図４では、反射部材４の片面にジグザグ型の凹凸２１が設けられており、また図５では、該ジグザグ型の凹凸２１が反射部材４の両面に設けられている。これにより反射効率を維持しつつ、極めて良好な放熱効果が得られる。また反射部材４の片面又は両面に前記ジグザグ型の凹凸に代えて凸部が丸みを帯びた波型を設けてもよいことは言うまでもない。On the other hand, thereflection member 4 shows a partial view of the heat dissipation structure in order to further improve the heat dissipation effect while maintaining the function as the reflection member. 4 to 9, FIGS. 4 and 5 include a zigzaguneven portion 21. That is, in FIG. 4, zigzaguneven portions 21 are provided on one surface of the reflectingmember 4, and in FIG. 5, the zigzaguneven portions 21 are provided on both surfaces of the reflectingmember 4. Thereby, a very good heat dissipation effect can be obtained while maintaining the reflection efficiency. Needless to say, a wave shape with rounded convex portions may be provided on one or both sides of the reflectingmember 4 instead of the zigzag-shaped concave and convex portions.

更に図６では、反射部材４の全体が波型２２に形成されている。図７では、図６に示す波型２２に形成された反射部材４に更に貫通孔２３が設けられている。このように構成することにより光反射兼放熱フードの役割と共にいっそうの放熱効果を得ることができる。図８は、反射部材４の表面にエンボス状凹凸模様２４を形成したものであり、放熱効果に優れていることはもちろんのこと、製造が簡単で、かつコスト削減にも寄与するという優れた効果を奏するものである。図９は、反射部材４の表面に形成する突起の形状が、円柱型、角柱型、円錐型、角錐型、逆角柱型、逆円錐型及び逆角錐型のいずれかを少なくとも一面に有するものからなり、具体的には、円柱型は円柱ａである。この他楕円柱でもよい。角柱型には、ｂ又はｃがあり、例えば、断面が三角形ｃ、四辺形ｂ、長方形、五角形又は六角形などであってもよい。更に円錐型ｄ、角錐型には三角錐ｅ、四角錐ｆ、逆角錐型には、逆三角錐ｈ、逆四角錐ｇなどが挙げられる。Further, in FIG. 6, the entire reflectingmember 4 is formed in acorrugated shape 22. In FIG. 7, a throughhole 23 is further provided in the reflectingmember 4 formed in thecorrugated shape 22 shown in FIG. 6. By comprising in this way, the further heat radiation effect can be acquired with the role of the light reflection and heat radiation hood. FIG. 8 shows an embossed concavo-convex pattern 24 formed on the surface of the reflectingmember 4 and is excellent in heat dissipation effect as well as being easy to manufacture and contributing to cost reduction. It plays. FIG. 9 shows that the shape of the protrusion formed on the surface of the reflectingmember 4 has at least one of a cylindrical shape, a prism shape, a cone shape, a pyramid shape, an inverted prism shape, an inverted cone shape, and an inverted pyramid shape. Specifically, the column type is a column a. In addition, an elliptic cylinder may be used. The prismatic type includes b or c. For example, the cross section may be a triangle c, a quadrangle b, a rectangle, a pentagon, or a hexagon. Further, the cone type d and the pyramid type include a triangular pyramid e, a quadrangular pyramid f, and the inverse pyramid type includes an inverted triangular pyramid h and an inverted quadrangular pyramid g.

本発明では、防塵・防水したＬＥＤ光源の反射及び放熱構造は、周知の防塵・防水手段を講じることができるが、具体例としては、ＬＥＤ光源を有する反射部材側を防塵・防水加工してもよく、この場合には、ＬＥＤ光源と反射部材とからなる表面に、例えばシリコーン等を被覆し、防水性を得たもので、放熱効果は特に反射部材の反対側の表面から放熱され、良好な防水特性と放熱効果が共に得られる。更に従来の発熱電球や省エネ電球にくらべＬＥＤ光源３は、遥かに放熱量がすくなく、かつ大きさも小さいので、防水器具と一体に構成してもよい。特に独立した防水器具中にＬＥＤ光源３を内蔵させることにより、より大きさを小さくすることができ、より軽量かつ低コストで防水性に優れた防止ＬＥＤ光源が得られる。したがって、本発明の防塵・防水手段は、上記に限定されるものではない。本発明においては、前記ＬＥＤ光源を有する反射部材側を防止加工したＬＥＤ光源と反射部材とからなることにより、ＬＥＤ光源を有する反射部材側のみを防止加工しても放熱性能の効率は減少することなく、放熱性能には全く問題はないという優れた効果を奏するものである。In the present invention, the reflection and heat dissipation structure of the dust-proof / waterproof LED light source can take well-known dustproof / waterproof means, but as a specific example, the reflective member side having the LED light source may be dust-proof / waterproof processed. Well, in this case, the surface consisting of the LED light source and the reflecting member is covered with, for example, silicone to obtain waterproofness, and the heat dissipation effect is particularly good because the heat is dissipated from the opposite surface of the reflecting member. Both waterproof properties and heat dissipation effect can be obtained. Furthermore, the LEDlight source 3 has far less heat dissipation and is smaller in size than conventional heat-generating bulbs and energy-saving bulbs, and may be configured integrally with a waterproof device. In particular, by incorporating theLED light source 3 in an independent waterproof device, the size can be further reduced, and a light-proof and low-cost prevention LED light source with excellent waterproof properties can be obtained. Therefore, the dustproof / waterproof means of the present invention is not limited to the above. In the present invention, the efficiency of the heat dissipation performance is reduced even if only the reflection member side having the LED light source is prevented by processing, by including the LED light source and the reflection member that prevent the reflection member side having the LED light source. In addition, there is an excellent effect that there is no problem in the heat dissipation performance.

本発明のＬＥＤ光源の反射及び放熱構造は、一例として、装飾効果を一段と良好なものとするために、クリスマスツリーの光源として用いることができる。この際、反射部材４は、長時間、ＬＥＤ光源を使用し続けると熱が蓄積するが、この熱は反射部材４のアルミニウム素材により吸収されて放熱されると共に、更にこの反射部材４は補助放熱部材１１を設けた場合は、反射板４の熱の一部は補助放熱部材１１へ移行し放散される。この他、照明用ＬＥＤ光源にも使用されるが、照明用ＬＥＤ光源として使用する場合、更に反射部材４の外面に接触してプラスチック製、金属製、又は陶磁器製のカバーを設けてもよく、又はこれらのカバーの中に反射部材４を内設してもよい。As an example, the LED light source reflection and heat dissipation structure of the present invention can be used as a light source for a Christmas tree in order to further improve the decoration effect. At this time, thereflection member 4 accumulates heat when the LED light source is continuously used for a long time, but this heat is absorbed and radiated by the aluminum material of thereflection member 4, and thereflection member 4 further radiates auxiliary heat. When themember 11 is provided, a part of the heat of thereflector 4 is transferred to the auxiliaryheat radiating member 11 and dissipated. In addition to this, it is also used for an LED light source for illumination, but when used as an LED light source for illumination, a cover made of plastic, metal, or ceramic may be provided in contact with the outer surface of the reflectingmember 4, Alternatively, the reflectingmember 4 may be provided inside these covers.

本発明では、前述の如き作用効果を発揮するので、その用途としては、クリスマスツリー用装飾光源として最良であると共に、更にその他家庭用、店舗用など各種の用途に装飾用光源、更には照明用光源としても広く使用することができ、実用上極めて有用なＬＥＤ光源の反射及び放熱構造である。In the present invention, since the above-described effects are exhibited, the use thereof is the best as a decoration light for a Christmas tree, and also a decoration light source for various uses such as home use and store use, and further for illumination. The LED light source reflection and heat dissipation structure can be widely used as a light source and is extremely useful in practice.
