1、SHOUMINGSHIYAN

半导体照明产品的可靠性评估的基础源自寿命试验,其电源和控制器件的寿命通常不超过10万小时。一般的电解电容的寿命为5000-6000小时/105℃,最好的寿命为10000小时/105℃,表面看这个时间与LED灯具的5万小时完全不匹配,但事实上许多纸面上的专家并不真正了解电解电容,电解电容遵循一个简单的规律,就是环境温度下降10℃,寿命增加一倍,通常电解电容在灯具中的工作温度因为同产品大不相同,led日光灯,led灯管内的温度通常在45℃—55℃,所以如果LED灯管使用的电解电容为105℃/10000小时时,电解电容实际寿命在100000小时左右,如果5000小时/105℃的,则电解电容寿命为50000小时左右。
