LED灯具寿命测试要做多少天?我看SGS发的报告是做10天,难道LED灯具驱动电源不用考量异常条件寿命。我看标准理解是有异常测试的要做7天,没有异常测试的要做10天,5 C3 e, k% e o5 T

这不是寿命测试吧,是耐久性测试 $ J1 i6 y" Z* b$ m+ ?" F你的LED灯具要看 CTL决议DSH0745 按1.1倍电压,做10天,21h on / 3h off作者: 520168 时间: 2013-11-22 11:10
做10天耐久也要21h on / 3h off?我一直以为做168小时才会有21h on / 3h off呢!作者: jsq123 时间: 2013-11-22 11:16
LED灯具的寿命测试只能通电测试,控制装置倒有办法测算寿命,依据美军标Mil-HDBK-217F。作者: jsspace 时间: 2013-11-22 11:39
