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。”8. Initial luminous flux and forward voltage at photometric measurement current 最初的光通量和正向电压度量测量电流在照片See individual test reports. The drive current used for luminous flux, forward voltage and chromaticity measurements is listed as “Measurement Current.” 看个人测试报告。用于驱动电流的光通量,正向电压测量及色度被列为“措施的观点电流。”9.
