The invention discloses a kind of LED single near light lens assembly for a car with a color elimination light, including a heat sink, a near light LED light source plate, a coloured lens and an external lens. The near light LED light source plate is installed on the rear wall of the heat sink, and the colourful lens is mounted on the rear wall of the heat sink through a lens bracket, so that the colourful lens is located near the light light of the light. The outer lens is installed at the front of the heat shield, and the outer edge of the outer lens is provided with a decorative ring, and the decorative ring is fixedly connected with the outer edge of the radiator hood. A kind of LED single near light lens assembly used in the invention uses a near light LED light source plate, a color elimination lens and an external lens to realize the near light function. The lens assembly has small occupancy space, no need to use the baffle, the structure is simple, the reliability is high, the use rate of the light efficiency is high, and the spot color of the spot circle can be eliminated effectively and the color of the spot color can be made. Purity can greatly improve the safety of driving at night, low cost, easy maintenance, low energy consumption and wide range of applications.

一种车用消彩光LED单近光透镜总成
本专利技术涉及一种车用消彩光LED单近光透镜总成。
技术介绍
目前,市面上直接使用透镜折射配光的单近光透镜,在光斑边缘或多或少都有彩色光斑(如黄色,紫色,蓝色),具有彩色的光斑会降低光照整体亮度,降低能量的利用率。
技术实现思路
为了解决以上技术问题,本专利技术提供一种车用消彩光LED单近光透镜总成,无需使用挡板,结构简单,通过透镜二次光学折射后可以消除光斑边缘彩色等不良现象,提高亮度,且能有效提高能量利用率,降低功耗,适合大面积推广。本专利技术的一种车用消彩光LED单近光透镜总成,包括散热罩、近光LED光源板、消彩光透镜和外部透镜,所述近光LED光源板安装在所述散热罩内的后壁上,所述消彩光透镜通过透镜支架安装在所述散热罩内的后壁上,使所述消彩光透镜位于所述近光LED光源板的正前方,所述外部透镜安装在所述散热罩的前方。本申请的车用消彩光LED单近光透镜总成在原有透镜总成的基础上增加了消彩光透镜,消彩光透镜安装在近光LED光源板和外部透镜之间,将LED发出的光先通过消彩光透镜进行折射后再通过外部透镜折射完成配光,消除光斑边缘彩色(如黄色,紫色,蓝色)等不亮现象,可靠性增加,有效提高能量利用率,精准度提高,亮度提高,降低功耗,减少生产工序。进一步的,所述消彩光透镜为前凸后凸的双凸凸透镜,所述外部透镜为前凸后平的平凸凸透镜。进一步的,所述外部透镜的凸面曲率不规则,纵向截面的曲率从上到下依次为k上、k纵中、k下,其中k上<k下<k纵中,横向截面的曲率从左到右依次为k左、k横中、k右,其中k左=k右& ...
