2.failure criteria
(失效標準)
- electrical failures:
(電性失效)
- vf>±10%(電壓值>±5%)
- ir(vr=5v)>10ua(反向電流>10ua)
- light output degradation:
(光通量衰減)
- flux degradation% >10% max ;>3% average
(光通量最大衰減>10%;平均衰減>3%)
- visual failures:
(外觀不良)
- broken or damaged package or lead(包裝破損)
- solder ability < 95% wetting(有效焊接面積< 95%)
- dimension out of tolerance(尺寸超出公差)
- discolor of lens(透鏡變色)
■note:it is required that the leds should be attached heat-sink when these leds are operating.
(備注:以上這些是要求在操作led的過程當中要重視散熱的問題)
