b、准备PCB板和LED灯珠,所述PCB板上设有用于给所述LED灯珠提供电源的焊接过孔,将所述LED灯珠的管脚穿过对应所述焊接过孔并伸出于PCB板,然后将所述LED灯珠的管脚与对应所述焊接过孔焊接连接;
c、准备金属材料的背板,所述背板包括侧壁和底板,所述背板上设有多个用于穿过所述翅片的翅片孔;
d、将散热器的翅片对应穿过所述背板的翅片孔,然后通过螺栓将所述基板的两端部与所述底板分别固定连接;
e、在所述散热器的贯通孔内灌入导热硅胶,在所述基板远离所述底板的表面上涂覆导热硅胶;
f、使所述LED灯珠的管脚对应插入所述基板的贯通孔内。
优选的,所述步骤f后还包括以下步骤:使所述LED灯珠的管脚伸出于所述贯通孔外侧的部分朝向所述翅片的端面弯折。
采用了上述技术方案后,本发明的有益效果是:
本发明的背光源生产组装方法制作成的背光源,LED灯珠通电散发的热量以及PCB板的热量可通过基板以及LED灯珠的管脚传递到翅片上散热,尤其是LED灯珠的管脚直接插入翅片的贯通孔,贯通孔内灌有导热硅胶,LED灯珠的管脚直接与翅片通过导热硅胶接触散热,大大提高了散热效果,使本发明的背光源散热效果好,使用寿命长。
