Description
本創作係揭露一種發光二極體路燈透鏡模組，特別尤指一種投射非對稱配光且運用於道路照明之發光二極體路燈透鏡模組。
The present invention discloses a light-emitting diode street light lens module, in particular, a light-emitting diode street light lens module that projects asymmetric light distribution and is applied to road illumination.
傳統的照明路燈大多是水銀燈，由於長時間使用下產生的高熱容易使燈泡的使用壽命縮短，耗電量高且不符環保，為達成節能減碳之目標，故已逐漸被具有亮度高、省電、壽命長等諸多優點之發光二極體(Light Emitting Diode, LED)燈具所取代。
Most of the traditional street lamps are mercury lamps. Due to the high heat generated during long-term use, the life of the bulb is shortened, the power consumption is high, and it is not environmentally friendly. In order to achieve the goal of energy saving and carbon reduction, it has been gradually brightened and saved. Light Emitting Diode (LED) lamps have been replaced by many advantages such as long life.
由於發光二極體並非點光源特性，所以發光二極體有與傳統光源完全不同的發光特性，其中光通量分佈皆為軸對稱光型，如此的對稱配光直接用於道路照明產生的路面配光，呈現圓形分佈的對稱光型，不符合道路長條形狀特性，使得許多光束投射到道路路面之外的地方形成浪費，使得照明效率不高而且照度均勻度也會不佳。
Since the light-emitting diode is not a point source characteristic, the light-emitting diode has completely different light-emitting characteristics from the conventional light source, wherein the light flux distribution is an axisymmetric light type, and such symmetric light distribution is directly used for road surface light distribution generated by road illumination. The symmetrical light pattern with a circular distribution does not conform to the shape of the road strip shape, so that many light beams are thrown to a place outside the road surface to form waste, so that the illumination efficiency is not high and the illumination uniformity is also poor.
