一种LED灯头
本技术涉及LED照明领域,具体涉及一种LED灯头。
技术介绍
随着LED技术的逐渐成熟,越来越多的照明领域被LED这个节能又环保的照明方式所占据,从家用照明到市政工程照明再到随身照明设备,处处都能看到LED灯珠的身影,其中LED手电筒是LED照明中占比较大的一块产业,当下LED灯头往往是通过LED灯珠配合反光罩实现聚光,目前LED灯珠往往被焊接在铜基板上,再通过铜基板与灯座配合添加导热硅脂实现导热,但铜基板与灯座之间仅仅依靠导热硅脂的粘性进行预固定,当反光罩装入后,通过在灯座上旋入灯帽,使灯帽挤压反光罩,使得反光罩底部压紧铜基板实现固定,但是这种结构虽然固定牢固,但接近于刚性连接,在受到震动或是灯头跌落时,往往会直接将震动传递至铜基板上的LED灯珠,造成LED灯珠损伤。
技术实现思路
基于上述问题,本技术目的在于提供一种散热效果佳,抗震性好,对铜基板无挤压的LED灯头。针对以上问题,提供了如下技术方案:一种LED灯头,包括灯座,所述灯座设有凹腔,所述凹腔内设有通过灯帽旋合固定的反光碗,所述凹腔内设有LED灯珠,所述LED灯珠底部设有铜基板,所述铜基板与凹腔底面贴合接触,其特征在于:所述铜基板与凹腔贴合的一面设有若干以铜基板中心环形均布设置的基板槽,所示基板槽内设有第一磁铁,所述凹腔底面上与基板槽对应位置处设有磁铁安装槽,所述磁铁安装槽内设有第二磁铁,所述第一磁铁与第二磁铁彼此吸引,所述铜基板与凹腔底面之间填充有导热硅脂,所述反光碗碗口设有翻缘,所述灯帽与灯座旋合以此固定翻缘实现反光碗的定位,所述反光碗碗底与铜基板表面间隙配合。上述结构中,通过第一磁 ...
