Abstract

本实用型公开一种带偏光且具有调光功能的LED护栏灯,其包括钢管支架、钢管、外罩、LED单元模块;两个相邻钢管支架支撑并固定钢管,外罩与钢管结构配合形成一腔体,LED单元模块设于该腔体内;所述LED单元模块包括PC面罩、铝型材、硅胶圈和偏光透镜;PC面罩与铝型材的结构配合,形成容纳LED光源的空腔,铝型材上设有PCB电路和硅胶圈,LED灯珠与PCB电路电性连接,偏光透镜罩于LED灯珠上。本实用新型的带偏光且具有调光功能的LED护栏灯,与现有技术相比,进行偏光、防眩光设计,且夜间根据路况进行灯光亮暗控制,从而消减行车安全事故的发生,有效的解决了现有技术之不足。本实用新型结构简单,易于实现产业化,且节能环保,具有很好的实用性。
The utility model discloses an LED guardrail lamp with light polarizing and dimming functions. The LED guardrail lamp comprises steel tube supports, a steel tube, outer covers and LED unit modules. The two adjacent steel tube supports are used for supporting and fixing the steel tube, the outer covers and the steel tube are structurally matched to form a cavity, and the LED unit modules are arranged in the cavity. The LED unit modules comprise PC surface covers, aluminum sectional materials, silica gel rings and light polarizing lenses. The PC surface covers are structurally matched with the aluminum sectional materials to form a cavity for containing an LED light source, PCB circuits and the silica gel rings are arranged on the aluminum sectional materials, LED lamp beads are electrically connected with the PCB circuits and the light polarizing lenses are arranged on the LED lamp beads in a covering mode. Compared with the prior art, the LED guardrail lamp with the light polarizing and dimming functions has the advantages that light polarizing and anti-dazzle design is carried out, the light brightness is controlled according to the road conditions at night, therefore, driving safety accidents are reduced, and the defects in the prior art are effectively overcome. The LED guardrail lamp with the light polarizing and dimming functions is simple in structure and environmentally friendly, saves energy and has good practicability, and industrialization is easy to realize.
