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
