Abstract

一种四椭球面LED投影汽车近光灯，包括支架，支架前端装有凸透镜，支架内后部设有铝基板，支架中部装有遮光板，铝基板上、下两个侧面分别装有两个LED灯，每个LED灯对应的支架内壁上均设有椭球面反射镜。本发明中，由于LED光源体积小，可使灯内布局更合理；采用LED光源可使灯内温度降低到60℃以下，大大减少水雾产生的可能性，能延长灯的各部件使用寿命；通过半剖面的设计，在减小体积的同时，充分利用了光源发光效率，减少光线浪费，能节电70%。

Description

四椭球面 LED 投影汽车前照灯
技术领域
本发明属于汽车车灯领域及其它用于射灯的领域，尤其涉及一种汽车前照灯。
背景技术
传统的汽车前照灯采用的多是白炽灯、卤素灯，气体放电灯等作为光源。采用投影式的前照灯，远光灯灯光组、近光灯灯光组、投射灯灯光组分别占据了灯体的大部分体积，从而使整灯外形设计受到很大限制。传统前照灯点亮后，灯内温度较高，极易产生水雾，影响外观和灯的其它部件寿命，而且耗电量也较大，不利于节能。
发明内容
本发明所要解决的技术问题是提供一种节约能源、寿命长、体积小的四椭球面LED 投影汽车前照灯。
为了解决上述技术问题采用以下技术方案：一种四椭球面 LED 投影汽车近光灯，包括支架，支架前端装有凸透镜，支架内后部设有铝基板，支架中部装有遮光板，铝基板上、下两个侧面分别装有两个 LED 灯，每个 LED 灯对应的支架内壁上均设有椭球面反射镜。
铝基板上装有四个LED 灯，相邻LED 灯的发光方向相反；在铝基板的上方和下方分别设有两个椭球面反射镜。
四个 LED 灯发出的光经过各自对应的椭球面反射镜反射汇聚于凸透镜的交点。
铝基板上带有散热器。
本发明中，由于 LED 光源体积小，可使灯内布局更合理；采用 LED 光源可使灯内温度降低到 60℃以下，大大减少水雾产生的可能性，能延长灯的各部件使用寿命 ；通过半剖面的设计，在减小体积的同时，充分利用了光源发光效率，减少光线浪费，能节电 70%。
附图说明
图 1 为本发明实施例 1 的结构示意图。
图 2 为本发明实施例 2 的结构示意图。
图 3 为本发明实施例 3 的结构示意图。
具体实施方式
实施例 1 ：如图 1 所示，一种四椭球面 LED 投影汽车远光灯，包括支架 2，支架前端装有凸透镜 1，支架 2 内后部设有带有散热器的铝基板 5，铝基板 5 上、下两个侧面分别装有两个 LED 灯 3，相邻 LED 灯的发光方向相反；每个 LED 灯 3 对应的支架内壁上均设有椭球面反射镜 4，在铝基板 5 的上方和下方分别设有两个椭球面反射镜 4。四个 LED 灯发出的光经过各自对应的椭球面反射镜反射汇聚于凸透镜的交点。
LED 灯为大功率白色光源，椭球面反射镜能对 LED 灯发出的光线进行反射和光线重新分布。工作原理：电源接通后，LED 灯发出的光通过椭球面反射镜反射后，经过遮光板遮挡一部分光线，再经过凸透镜后可形成清晰的明暗截止线射出。
实施例 2 ：如图 2 所示，一种四椭球面 LED 投影汽车近光灯，包括支架 6，支架前端装有凸透镜 1，支架 2 中部装有遮光板 6，支架 2 内后部设有带有散热器的铝基板5。
其他结构同实施例 1。
实施例 3 ：如图 3 所示，一种彩色 LED 投影射灯，铝基板 5 上、下两个侧面分别装有两个LED 灯，从前到后依次为红色LED 灯3a、绿色LED 灯3b、蓝色LED 灯3c、白色LED灯3d，相邻 LED 灯的发光方向相反；红色 LED 灯 3a、绿色 LED 灯 3b、蓝色 LED 灯 3c、白色 LED 灯 3d 分别对应支架内壁上设置的椭球面反射镜 4a、4b、4c、4d。通过四个不同颜色 LED 的明暗混色，产生各种不同颜色的灯光。
其他结构同实施例 1。
