Description

小功率LED实现高亮度的光导结构
技术领域
本发明涉及汽车配件技术领域，特别涉及小功率LED实现高亮度的光导结构。
背景技术
汽车大灯，也称汽车前照灯、汽车LED日行灯，作为汽车的眼睛，不仅关系到一个车主的外在形象，更与夜间开车或坏天气条件下的安全驾驶紧密联系，目前，市面上车灯内使用到的光导与LED的配合结构中。
但是现有的LED汽车灯不足之处在于：1、LED发出的光90度左右入射到光导中，与LED成一定夹角的光无法入射到光导中，2、大多数的光导与PCBA不是安装在同一个件上，而由于模具原因，无法做光导与PCBA的直接限位结构，造成实际安装好后LED与光导尺寸链大，最终实际产品安装好后LED与光导的设计位置有一定偏差，为此，我们提出小功率LED实现高亮度的光导结构。
发明内容
本发明的主要目的在于提供小功率LED实现高亮度的光导结构，可以有效解决背景技术中的问题。
为实现上述目的，本发明采取的技术方案为：
小功率LED实现高亮度的光导结构，包括支架和聚光器，所述支架顶部设置有PCBA，所述PCBA顶部通过安装座安装有LED灯芯，所述PCBA顶部外侧设置有聚光器，所述聚光器内部胶合有光学反射镜面，所述聚光器顶部套设有导光柱。
进一步地，所述支架顶部两端焊接有内螺纹固定管。
进一步地，所述PCBA两端开设有二号安装孔。
进一步地，所述聚光器两端开设有一号安装孔，所述聚光器为金属铜材料制成。
进一步地，所述聚光器内侧开设有定位卡槽，所述定位卡槽的数量为多个。
与现有技术相比，本发明具有如下有益效果：
1.通过设置PCBA、光学反射镜面和内螺纹固定管，人员将二号安装孔套在内螺纹固定管外侧，使PCBA安装在支架上，PCBA顶部通过安装座安装有LED灯芯，人员将一号安装孔套在内螺纹固定管外侧，将聚光器安装在PCBA顶部，聚光器安装后套在LED灯芯外侧，通过内侧的多个光学反射镜面对LED灯芯发出的光线进行约束、反射，人员使用螺栓通过内螺纹固定管将聚光器和PCBA固定住。
2.通过设置导光柱、定位卡槽和聚光器，将导光柱插入聚光器内并固定，聚光器内的多个定位卡槽可以对导光柱进行固定，同时可以解决实际安装中LED与光导之间的位置与设计位置有一定偏差的问题，从而提高光学利用率，聚光器由金属铜材料制成，导热性能好，可以有效进行散热。
