2.failure criteria
(失效标准)
- electrical failures:
(电性失效)
- vf>±10%(电压值>±5%)
- ir(vr=5v)>10ua(反向电流>10ua)
- light output degradation:
(光通量衰减)
- flux degradation% >10% max ;>3% average
(光通量最大衰减>10%;平均衰减>3%)
- visual failures:
(外观不良)
- broken or damaged package or lead(包装破损)
- solder ability < 95% wetting(有效焊接面积< 95%)
- dimension out of tolerance(尺寸超出公差)
- discolor of lens(透镜变色)
■note:it is required that the leds should be attached heat-sink when these leds are operating.
(备注:以上这些是要求在操作led的过程当中要重视散热的问题)
