發光二極體燈具 Light-emitting diode lamp

本發明涉及一種照明裝置，特別係指一種發光二極體燈具。 The invention relates to a lighting device, in particular to a light-emitting diode lamp.

發光二極體光源作為一種新興之第三代光源，雖然現在還不能大規模取代傳統之白熾燈，惟，其具有工作壽命長、節能、環保等優點，而普遍被市場所看好。而且，目前由發光二極體組成之模組能產生大功率、高亮度之光源，完全可以取代現有白熾燈實現室內外照明，也將廣泛地、革命性地取代傳統之白熾燈等現有之光源，進而成為符合節能環保主題之主要光源。 As a new generation of light source, the light-emitting diode light source can not replace the traditional incandescent lamp on a large scale. However, it has the advantages of long working life, energy saving and environmental protection, and is generally favored by the market. Moreover, the module composed of the light-emitting diode can generate a high-power, high-brightness light source, which can completely replace the existing incandescent lamp to achieve indoor and outdoor illumination, and will also widely and revolutionarily replace the existing light source such as the traditional incandescent lamp. And become the main light source in line with the theme of energy conservation and environmental protection.

隨著發光二極體之相關產品技術不斷發展成熟，發光二極體燈具作為新型環保，節能之下一代光源產品，在生活中被人們越來越多之廣泛應用，尤係在道路照明，由於發光二極體自身節能環保之優點，以發光二極體為光源之路燈將取代以白熾燈等為光源之傳統之路燈之將係必然趨勢。然而，傳統戶外照明燈之安裝使用，基本上都以燈桿作為支撐體，該燈具安裝在燈桿支壁上並懸掛在高空之中，因此在燈具之安裝及維護上極為不方便。 As the related product technology of the light-emitting diodes continues to mature and mature, the light-emitting diode lamps, as the new environmentally-friendly and energy-saving next-generation light source products, are increasingly used in people's lives, especially in road lighting. The advantages of the energy-saving and environmental protection of the light-emitting diode itself are that the street lamp with the light-emitting diode as the light source will replace the traditional street lamp with the incandescent lamp as the light source. However, the installation and use of the traditional outdoor lighting lamp basically uses the light pole as a support body, and the light fixture is installed on the wall of the light pole and suspended in the high air, so it is extremely inconvenient in the installation and maintenance of the light fixture.

有鑒於此，有必要提供一種便於安裝及維護之發光二極體燈具。 In view of this, it is necessary to provide a light-emitting diode lamp that is easy to install and maintain.

上述發光二極體燈具處於組裝狀態時，發光二極體模組20貼設在散熱器10基板12前側面且導光模組30一一對應地安裝在發光二極體模組30上；散熱器10容置在殼體40內且散熱器20之基板12垂直地豎立在殼體40下水平板44上，且散熱器10基板12貼設有發光二極體模組30之前側面朝向殼體40之開口42，散熱器10後側之散熱片14夾置在基板12與殼體40背板46之間且向後靠近背板46之通氣孔460，以使散熱片14具有較好之空氣流通性；該蓋體50封蓋殼體40之開口42且該蓋體50之外周緣與開口42之內緣配合而將散熱器10等封裝於蓋體50與殼體40形成之封裝空間內。 When the light-emitting diode lamp is in an assembled state, the light-emitting diode module 20 is attached to the front side of the substrate 12 of the heat sink 10, and the light-guiding module 30 is mounted on the light-emitting diode module 30 one by one; The substrate 10 is disposed in the housing 40 and the substrate 12 of the heat sink 20 is vertically erected on the lower horizontal plate 44 of the housing 40, and the front surface of the heat sink 10 substrate 12 is attached to the front surface of the light emitting diode module 30 toward the housing 40.

上述發光二極體燈具在使用時，發光二極體燈具殼體40之下水平板44直接貼設在需要照明道路之路邊，使發光二極體燈具直接豎立安裝在地面上，所以上述發光二極體燈具相對懸掛在高空中之傳統路燈來說更便於安裝和維護，同時無須使用燈桿，降低工程投資。上述發光二極體燈具之發光二極體模組20產生之熱量直接被散熱器10基板12吸收後均勻分佈到散熱片14上，再由封裝於殼體40內之散熱片14通過殼體40上之通氣孔460散發到周圍環境中去，從而達冷卻對發光二極體模組20之目之。此外，在照明效果方面上述發光二極體燈具直接安裝在路邊，其照明效果更加明顯，可避免燈具之傳統安裝中，由於燈具與照射路面距離較遠而導致之光能浪費；在使用中，發光二極體燈具之照射方向一般與道路上行人或車輛之前進方向相反，以使照向行人或車輛之燈光在行人或車輛之後面產生陰影，同時會產生明顯之逆光照明之效果，使路面物體之輪廓更加清晰，而如果發光二極體燈具之照射方向與道路上行人或車輛之前進方向相同，則會在行人或車輛之前面產生陰影而影響照明效果。 When the above-mentioned light-emitting diode lamp is in use, the horizontal plate 44 under the light-emitting diode lamp housing 40 is directly attached to the roadside where the road needs to be illuminated, so that the light is emitted. The diode lamp is directly erected on the ground, so the above-mentioned LED lamp is easier to install and maintain than the traditional street lamp suspended in the sky, and the lamp pole is not needed, thereby reducing engineering investment. The heat generated by the LED module 20 of the LED device is directly absorbed by the substrate 12 of the heat sink 10 and evenly distributed to the heat sink 14. The heat sink 14 encapsulated in the housing 40 passes through the housing 40. The venting holes 460 are vented to the surrounding environment for cooling to the LED module 20. In addition, in terms of lighting effect, the above-mentioned light-emitting diode lamp is directly installed on the roadside, and the lighting effect thereof is more obvious, which can avoid the waste of light energy caused by the distance between the lamp and the irradiated road surface in the traditional installation of the lamp; in use The illumination direction of the light-emitting diode lamp is generally opposite to that of the pedestrian or the vehicle in front of the road, so that the light of the pedestrian or the vehicle is shadowed behind the pedestrian or the vehicle, and the effect of the backlight backlight is obviously generated. The contour of the pavement object is clearer, and if the illumination direction of the LED is the same as that of the pedestrian or the vehicle, the shadow will be affected in front of the pedestrian or the vehicle to affect the lighting effect.

上述導光單元34獨立設計且通過與單個發光二極體模組20對應之安裝架32安裝固定到發光二極體模組20上，因此所述獨立之導光單元34可以組成各種式樣之導光模組，以適用到不同燈具之發光模組上。 The light guiding unit 34 is independently designed and fixed to the LED module 20 by a mounting bracket 32 corresponding to the single LED module 20, so that the independent light guiding unit 34 can form various styles. The light module is applied to the light-emitting module of different lamps.
