The invention discloses an independent automobile license plate lamp. The left end and the right end of a license plate are each provided with a same light source system; each light source system comprises a lens, a lamp shell and an LED circuit board, two light sources, namely a light source I and a light source II, are arranged on the LED circuit board, the lens comprises a light distribution area I and a light distribution area II, and the lens II comprises an imitated convex lens area, a bevel incident area, a total reflection area and an emergent area. Illuminating light sources are designed at the two ends of a license plate lamp body respectively. Two groups of light sources are designed for each end illumination; the two groups of light sources are respectively responsible for twoillumination areas; the lens areas corresponding to the two groups of light sources are respectively subjected to light distribution design, so that the illumination requirement of a rear license plate can be met by using one license plate lamp, and the length of the lamp body is smaller than 1/2 of that of the license plate required to be illuminated, so that light in a limited space can be moreaccurately distributed, guided and stopped from emitting light to an unexpected area.
本发明公开了一种独体式汽车牌照灯,在牌照的左端和右端,各设置一组相同的光源系统,光源系统包括配光镜、灯壳、LED线路板,LED线路板上设置有两颗光源,分别是光源一和光源二,配光镜包括配光区域一和配光区域二,配光镜二包括仿凸透镜区域、折角入射区域、全反射区域、出射区域。本发明在牌照灯体两端分别设计照明光源,每端照明设计两组光源,分别负责为两个照明区域,分别对两组光源对应的配光镜区域进行配光设计,从而使用一个牌照灯即可满足后牌照板的照明要求,且其灯体长度小于所需照明牌照板的1/2,使有限的空间内灯光能够更准确的分配和引导,截止向不期望区域发出的光。
