XLamp XP-E White LEDs (Revision 1)
1. Number of LED light sources tested /LED光源
数量试验
See individual test reports.见测试报告
2. Description of LED light sources LED光源的描述XLamp XP-E White LEDs (XPEWHT)
All measurements provided are LED package measurements.
3. Description of auxiliary equipment测试设备描述Instrument Systems ISP-500 Integrating Sphere
Instrument Systems CAS-140 Spectrometer Keithley 2420 Sourcemeter
4. Operating cycle 循环周期LED packages are driven at constant current.
5. Ambient conditions 环境条件LED packages are operated in environmental
control chambers. The temperature of the
ambient air around the LED packages is actively
controlled by air flowing through the chamber.
TA : See individual test reports
RH : < 45%
Air flow : 800 CFM 包装是运作了环境控制室。
周围
的空气的温度在LED包是乘飞机主动控制流过室。
助教:看个人测试报告
湿度,< 45%
空气流动:800 CFM立方英尺每分钟
6. Case temperature情况下温度The case temperature measurement point is shown in
the XLamp XP-E Soldering & Handling document
(AP25). 如此的温度测量点被证明在XLamp XP-E焊
接和处理文件(AP25)。
7. Drive current of the LED light source during lifetime test. LED驱动电流See individual test reports. The drive current used during lifetime testing is listed as “Drive Current.”看个人测试报告。
驱动电流用在一生的测试被列为“驱动电流。
