Description
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.

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.
綜上所述,本發明符合發明專利要件,爰依法提出專利申請。惟,以上所述者僅為本發明之較佳實施例,舉凡熟悉本案技藝之人士,在爰依本發明精神所作之等效修飾或變化,皆應涵蓋於以下之申請專利範圍內。 In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
