Description

一种新型投影灯
技术领域
本发明涉及投影灯设计领域，尤其涉及一种新型投影灯。
背景技术
随着LED光源在汽车灯具中的大规模使用，LED前灯也逐渐在前灯市场中占据一席之地，并以较快的速度增长，其中，LED前灯投影灯作为LED前灯的核心模块，其设计方法也受到越来越多车灯企业及主机厂的关注与重视。现有技术中存在的投影灯的体积较大，重量较重，且成本较高，不能满足生产需要。
发明内容
本发明的目的是克服上述现有技术存在的缺陷，提供一种体积较小、重量较低且加工成本较低的新型投影灯。
本发明解决其技术问题所采用的技术方案是：一种新型投影灯，包括安装架、透镜和散热器，透镜和散热架分别固定在安装架的两侧，散热器上固定有近光LED线路板、反射镜、挡板和远光LED线路板，挡板包括平板和反射碗，反射碗固定在平板的一侧板面，平板的一侧边缘为凹弧形反射面，当近光LED线路板通电时，近光LED线路板发出的光线经反射镜反射至反射面处，再通过透镜形成近光截止线；当远光LED线路板通电时，远光LED线路板发出的光线经反射碗反射至透镜形成远光图案。
优选的，所述挡板的整个外表面覆盖铝层。
进一步的，所述反射面所在的平板边缘处的厚度在0.2mm以内。
有益效果：本发明将反射镜和挡板集为一体，使得同一个投影灯能够实现远、近光功能，当需要近光时，接通近光LED线路板，近光LED线路板发出的光线经反射镜反射至反射面处，再通过透镜形成近光截止线；当需要远光时，接通远光LED线路板，远光LED线路板发出的光线经反射碗反射至透镜形成远光图案，使用较为方便，远、近光功能集成在一个投影灯中，大大减小体积，重量较低且加工成本较低。

具体实施方式
下面结合图1-4，对本发明作进一步的描述。
一种新型投影灯，包括安装架10、透镜20和散热器30，透镜20和散热架30分别固定在安装架10的两侧，散热器30上固定有近光LED线路板40、反射镜50、挡板60和远光LED线路板70，挡板60包括平板61和反射碗62，反射碗62固定在平板61的一侧板面，平板61的一侧边缘为凹弧形反射面611，当近光LED线路板40通电时，近光LED线路板40发出的光线经反射镜50反射至反射面611处，再通过透镜20形成近光截止线；当远光LED线路板70通电时，远光LED线路板70发出的光线经反射碗62反射至透镜20形成远光图案。本发明将反射镜50和挡板60集为一体，使得同一个投影灯能够实现远、近光功能，当需要近光时，接通近光LED线路板40，近光LED线路板40发出的光线经反射镜50反射至反射面611处，再通过透镜20形成近光截止线；当需要远光时，接通远光LED线路板70，远光LED线路板70发出的光线经反射碗62反射至透镜20形成远光图案，使用较为方便，远、近光功能集成在一个投影灯中，大大减小体积，重量较低且加工成本较低。
优选的方案：所述挡板60的整个外表面覆盖铝层，提高挡板60的反射率以提高投影灯的光学效率。
进一步的，所述反射面611所在的平板61边缘处的厚度在0.2mm以内。保证最佳的反射效果。
应当理解，以上所描述的具体实施例仅用于解释本发明，并不用于限定本发明。由本发明的精神所引伸出的显而易见的变化或变动仍处于本发明的保护范围之中。
