Description

本発明は照明装置に関する。 The present invention relates to a lighting device.

従来のＬＥＤライトの一例として、図１および２に示すように、シェル１０、基板１１、およびランプカバー１２を備える。その中のシェルは、アルミ押出一体成形によって作られ、ランプカバーは通常プラスチック押出一体成形によって作られる。 As an example of a conventional LED light, as shown in FIGS. 1 and 2, a shell 10, a substrate 11, and a lamp cover 12 are provided.

ところが、図１および２に記載の従来のＬＥＤライトの場合、基板に複数個のＬＥＤライトを設置することにより、温度が高くなる。しかしながら、基板２１の表面に塗布した熱伝導性ゴムのみを通して、熱をシェル２０へ伝導し、シェル２０により放熱するので、放熱効率が低い。よって、ＬＥＤライトにより生じる熱を適時に放出することができないため、ＬＥＤライトは、常に高温環境下に置かれ、オーバーヒートにより故障するおそれがある。 However, in the case of the conventional LED lights shown in FIGS. 1 and 2, the temperature is increased by installing a plurality of LED lights on the substrate. However, since heat is conducted to the shell 20 only through the heat conductive rubber applied to the surface of the substrate 21 and is radiated by the shell 20, the heat radiation efficiency is low. Therefore, since the heat generated by the LED light cannot be released in a timely manner, the LED light is always placed in a high-temperature environment, and there is a risk of failure due to overheating.

また、図３および４に記載の従来のＬＥＤライトの場合、基板２１は密閉されたシェル２０とランプカバー２２との間に設置され、ＬＥＤライトにより生じる熱は、シェルのみに吸收放熱される。よって、放熱効率がより低くなり、ＬＥＤライトにより生じる高温を適時に放出することができないため、オーバーヒートによるＬＥＤライトの故障、ＬＥＤライトの寿命短縮等の問題が生じる。 3 and 4, the substrate 21 is installed between the sealed shell 20 and the lamp cover 22, and heat generated by the LED light is absorbed and radiated only by the shell. Therefore, since the heat dissipation efficiency becomes lower and the high temperature generated by the LED light cannot be released in a timely manner, problems such as failure of the LED light due to overheating and shortening of the life of the LED light occur.

本発明の目的は、放熱性能が優れた照明装置を提供することにある。 The objective of this invention is providing the illuminating device excellent in the heat dissipation performance.

本発明では、シェルは、プラスチック材料または金属材料によって作られ、一つ以上のシェル素子で構成される。 In the present invention, the shell is made of a plastic material or a metal material and is composed of one or more shell elements.

また、シェルは複数個のシェル素子で構成され、各シェル素子は複数の放熱対流穴を有する。これにより、空気の対流放熱効果を生じさせる。 The shell is composed of a plurality of shell elements, and each shell element has a plurality of heat convection holes. Thereby, the convection heat dissipation effect of air is produced.

基板の表面には熱伝導性塗料が塗布される。熱伝導性塗料により、ＬＥＤライトにより生じる熱を吸収し、輻射放熱効果をえる。 A thermally conductive paint is applied to the surface of the substrate. The heat conductive paint absorbs the heat generated by the LED light and obtains a radiation heat dissipation effect.

本発明では、シェルの放熱対流穴により、空気の対流放熱効果を得る。また、基板に設置される熱伝導性塗料により、輻射放熱効果を得る。本発明では同時に二種以上の放熱方法を提供するので、ＬＥＤライトにより生じる熱は、効率よく拡散され、ＬＥＤライトのオーバーヒートを抑制し、ＬＥＤライトの使用寿命を延ばすことができる。 In the present invention, the convection heat radiation effect of air is obtained by the heat convection hole of the shell. Moreover, the radiation heat dissipation effect is acquired by the heat conductive coating material installed in a board | substrate. Since the present invention provides two or more heat dissipation methods at the same time, the heat generated by the LED light is efficiently diffused, the overheating of the LED light can be suppressed, and the service life of the LED light can be extended.

本発明の一実施形態を図面に基づいて説明する。
（一実施形態）
第１実施形態を図５−１１に基づいて説明する。
シェル３は、プラスチック材料または金属材料によって作られ、単一シェル（図１４の第４実施例参照）または複数のシェル素子３ａ（図１０、図１２の第１実施例と図１３の第３実施例参照）によって構成される。シェル３は、複数のシェル素子３ａによって構成されるシェル３である場合、一つ一つのシェル素子３ａとランプカバー５とを組み合わせるだけでできる。粘着材料で粘着することにより、複数個のシェル素子３ａによって単一のシェル３を構成する（図５、１０、１２、１３参照）。 An embodiment of the present invention will be described with reference to the drawings.
(One embodiment)
A first embodiment will be described with reference to FIGS.
The shell 3 is made of a plastic material or a metal material, and a single shell (see the fourth embodiment of FIG. 14) or a plurality of shell elements 3a (the first embodiment of FIGS. 10, 12 and the third embodiment of FIG. 13). (See example). When the shell 3 is a shell 3 composed of a plurality of shell elements 3 a, the shell 3 can be simply combined with each shell element 3 a and the lamp cover 5. By adhering with an adhesive material, a single shell 3 is constituted by a plurality of shell elements 3a (see FIGS. 5, 10, 12, and 13).

シェル３には、複数の放熱対流穴３０（図６と７）を有する。また、ニーズによって放熱対流穴３０の設置密度を変更することができる。シェル３の側辺にある放熱対流穴３０を利用し、常温空気をシェル３と基板４によって形成される空間３３に入れ、シェル３の上方にある放熱対流穴３０を経て、熱エネルギーを空間３３に散布する。これにより、空気の対流することにより放熱する。ＬＥＤライト４０により生じる熱は、空気対流によって、速やかに拡散する。放熱対流穴３０の設置は、図６と７の方法に制限されない。 The shell 3 has a plurality of heat dissipation convection holes 30 (FIGS. 6 and 7). Moreover, the installation density of the heat dissipation convection holes 30 can be changed according to needs. Using the heat dissipation convection hole 30 on the side of the shell 3, normal temperature air is put into the space 33 formed by the shell 3 and the substrate 4, and the heat energy is transferred to the space 33 through the heat dissipation convection hole 30 above the shell 3. To spray. Thus, heat is dissipated by convection of air. The heat generated by the LED light 40 is quickly diffused by air convection. Installation of the heat dissipation convection hole 30 is not limited to the method of FIGS.

シェル３の内側には、二つの設置溝３１が設けられている。基板４を設置するために（図１０と１１参照）、二つの設置溝３１は対称となるよう設けられている。ランプカバー５を設置するために（図８と９参照）、シェル３の外側には二つの結合溝３２が設けられている。二つの結合溝３２は対称となるよう設けられている。 Two installation grooves 31 are provided inside the shell 3. In order to install the substrate 4 (see FIGS. 10 and 11), the two installation grooves 31 are provided symmetrically. In order to install the lamp cover 5 (see FIGS. 8 and 9), two coupling grooves 32 are provided outside the shell 3. The two coupling grooves 32 are provided symmetrically.

基板４は、シェル３の設置溝３１の中に設置される。また、基板４には複数個のＬＥＤライト４０（図１０と１１参照）が設けられる。これにより、ライトの光を提供する。基板の表面には熱伝導性塗料４１が塗布される。ＬＥＤライト４０により熱が生じると、熱は熱伝導性塗料４１に吸收され、輻射することにより拡散する。また、熱は、シェル３の放熱対流穴３０により、外側に拡散する。基板には、複数の気孔４２を有する。ＬＥＤライト４０を点灯することにより生じる熱エネルギーは、基板４とランプカバー５との間の空間４３に拡散する。気孔４２は、基板４とシェル３との間の空間３３中へ熱エネルギーの拡散を加速する。そして、基板４とシェル３との間の空間３３中の熱エネルギーはシェル３の放熱対流穴３０を経て、外部に排出される。これにより、熱の拡散速度が速やかに行われ、ＬＥＤライトのあるべき使用寿命を維持する。 The substrate 4 is installed in the installation groove 31 of the shell 3. The substrate 4 is provided with a plurality of LED lights 40 (see FIGS. 10 and 11). This provides the light of the light. A thermally conductive paint 41 is applied to the surface of the substrate. When heat is generated by the LED light 40, the heat is absorbed by the heat conductive paint 41 and diffused by radiation. Further, the heat is diffused to the outside through the heat dissipation convection hole 30 of the shell 3. The substrate has a plurality of pores 42. Thermal energy generated by turning on the LED light 40 diffuses into the space 43 between the substrate 4 and the lamp cover 5. The pores 42 accelerate the diffusion of thermal energy into the space 33 between the substrate 4 and the shell 3. The heat energy in the space 33 between the substrate 4 and the shell 3 is discharged to the outside through the heat dissipation convection hole 30 of the shell 3. Thereby, the spreading | diffusion rate of a heat | fever is performed rapidly and the useful life which an LED light should have is maintained.

ランプカバー５は、プラスチックにより一体成形によって作られ、両側に結合部５０を設けることによって、前述したシェル３の結合溝３２と結合する（図８−１１参照）。ランプカバー５は、ＬＥＤライト４０の光を透過させる。 The lamp cover 5 is made of plastic by integral molding, and is coupled to the coupling groove 32 of the shell 3 described above by providing coupling portions 50 on both sides (see FIGS. 8-11). The lamp cover 5 transmits the light from the LED light 40.

組合せ過程において、まずシェル３の各シェル素子３ａとランプカバー５とを組合せてから、基板をシェル３とランプカバー５との間、またシェル３の二つの設置溝３１の中に設置する。最後に、ライトの両側に電気接続素子６０、６１（電気接続素子は先行技術範囲に属し、省略）を設置する。 In the combination process, the shell elements 3 a of the shell 3 and the lamp cover 5 are first combined, and then the substrate is installed between the shell 3 and the lamp cover 5 and in the two installation grooves 31 of the shell 3. Finally, electrical connection elements 60 and 61 (the electrical connection elements belong to the prior art range and are omitted) are installed on both sides of the light.

上述したように、本実施形態では、シェル３に放熱対流穴３０を設置することによって、空気の対流放熱効果を生じる。また、基板４に熱伝導塗料４１を塗布することによって、同時に二種以上の放熱効果を提供し、放熱効率を向上させる。ＬＥＤライト４０がシェル３およびランプカバー５によって構成される空間の熱を速やかに外部に放出するので、ＬＥＤライトの環境温度を速やかに低減し、ＬＥＤライト４０のオーバーヒートを抑制することができる。また、ＬＥＤライトの使用寿命を維持し、排出される二酸化炭素を削減し、省エネ効果を得ることができる。 As described above, in the present embodiment, the convection heat radiation effect of air is produced by installing the heat convection hole 30 in the shell 3. Moreover, by applying the heat conductive paint 41 to the substrate 4, two or more kinds of heat radiation effects are simultaneously provided, and the heat radiation efficiency is improved. Since the LED light 40 quickly releases the heat of the space constituted by the shell 3 and the lamp cover 5 to the outside, the environmental temperature of the LED light can be quickly reduced and overheating of the LED light 40 can be suppressed. Moreover, the service life of the LED light can be maintained, the carbon dioxide discharged can be reduced, and an energy saving effect can be obtained.
