The utility model relates to an automobile LED light emitting plate, which comprises a LED lamp, a light guide plate and a reflection film. The reflection film is set at the bottom of the light guide plate. The side of the light guide plate is provided with a capacitive opening of the LED lamp, and the light surface of the light guide plate is provided with a light shield and the light shield is near the side of the light entry surface. The LED light plate of the car adds the light guide plate. The light emitted by the LED lamp is light from the side of the guide plate. The light from the front of the guide plate is out. The light guide plate itself has good light conduction, diffusion, uniformity and no glare. It can solve the unreasonable spectral distribution of a part of the LED lamp, and the shading layer covers the brightest place. Live, the overall light will be more uniform, there is no obvious bright edge or dark edge, and the traditional single LED luminescence or neon light bulb luminescence comparison, so that the customer's visual feeling is better and more comfortable, not easy to produce visual fatigue, LED luminescent plate more environmental protection, energy saving, long service life and so on.
【技术实现步骤摘要】
一种汽车LED发光板
本技术涉及汽车照明
,尤其涉及一种汽车LED发光板。
技术介绍
在汽车内部有一些小功率小面积的照明光源,可以解决车内局部照明的问题,传统氖灯泡寿命短,光衰快,所以逐渐被更加环保节能的LED灯取代,但是LED灯质量参差不齐,低价的LED灯光谱分布不够合理,照明效果差强人意,高价的LED灯光谱虽然分布合理,但成本会大幅增加;另外LED灯的出光特点,也决定了光线不够均匀、刺眼、光照范围小、光弱等,设置多颗LED灯可以扩大光照范围,但功耗变大,有待改进。
技术实现思路
本技术的目的在于提供一种出光均匀、光照角度宽、不刺眼、无眩光、环保节能的汽车LED发光板。本技术提供的技术方案为:一种汽车LED发光板,包括LED灯、导光板和反射膜,所述反射膜设置在导光板的底面,所述导光板侧面设有LED灯的容置口,所述导光板的出光面上设有遮光层,所述遮光层靠近入光面的一侧。其中,所述遮光层为黑银层。其中,所述导光板的出光面还设有让光效更加均匀的雾化扩散膜或扩散板。其中,所述导光板的出光面为光滑面,导光板的底面为光学网点面。其中,所述导光板的出光面为磨砂面。其中,所述发光板还包括灯板,所述灯板上设有外接的电源线,所述灯板设置在导光板的入光面,所述LED灯设置在灯板上且与导光板上的容置口位置相对应。其中,所述LED灯设置在客户PCB板上,所述导光板的底面设有背胶,用于与客户PCB板固定连接。本技术的有益效果为:所述汽车LED发光板增加了导光板,导光板底面设有反射膜,LED灯发出的光线从导光板侧面入光,从导光板的正面出光,导光板本身具有很好的光传导、扩散、均匀、光照角 ...
