(Dongguan). is located at Pu Long Cun 69, Puxinghu Industrial Area, Tangxia Town, Dongguan, Guangdong, P.R.China. 1.4 Description of Auxiliary Equipment Device Manufacture Model No Serial No Test Range Calibration date Calibration due date Integral Sphere EVERFINE Diameter 0.3m m Programmable Test Power for LEDs High accuracy array spectroradiometer EVERFINE LED300E V/2000mA EVERFINE HAAS T nm Standard Light Source EVERFINE D N/A Precision digital stabilized DC power supply Multilayer aging machine Digital CC&CV DC Power Supply Digital CC&CV DC Power Supply EVERFINE WY605-V110 G115987CJ VA BACL B C~110 C EVERFINE WY (50/15A) EVERFINE WY (50/15A) Operating Cycle Samples are driven with a constant direct current (DC) 1.6 Ambient Conditions For lumen maintenance test, samples were operated in thermal chambers with minimal ambient airflow. For long term reliability test, the case temperature was controlled by mounting several thermocouples on a sample reliability stress board at the designated thermal measurement point, as shown in APPENDIX. The ambient temperature T A was measured by several thermocouples at a distance of 5 mm above the reliability test board. The relative humidity within chamber was less than 65%. For photometry measurement, temperature was set to 25 C ± 2 C, RH <65%. 1.7 Photometry Measurement Uncertainty The uncertainty of the light output (luminous flux) measurements is U=1.59% (K=2), at the 95% confidence level. The uncertainty of the correlated color temperature measurements is U=21K (K=2), at the 95% confidence level. The uncertainty of the CRI is U=1.7 (K=2), at the 95% confidence level. This calibration results traceable to the NATIONAL INSTITUTE OF METROLOGY (NIM). Report No. RSZ M1 Page 4 of 14 IESNA LM Test Report

5 1.8 Sample Set Sampling Method: LED samples for IESNA LM-80 testing consist of units built from a minimum of three manufacturing lots with each manufacturing lot built from different wafer lots built on non-consecutive days. These manufacturing lots are picked to represent a wide parametric distribution. Each Sample is soldered to all of the reliability stress boards for a given set of IESNA LM-80 tests. Sample Size: Total 90Pcs; Each Ts test condition 30Pcs The samples tested at Ts 55 C, Ts 85 C and Ts 105 C were received at and tested during to The samples were numbered from 1to 30, 31 to 60 and 61 to 90 Data Set 1: 55 C, 200mA Part Number: Number of Units: Actual Case Temperature(T S ): Actual Ambient Temperature(T A ): Life Test Drive Current: Measurement Current: Data Set 2: 85 C,200mA Part Number: Number of Units: Actual Case Temperature(T S ): Actual Ambient Temperature(T A ): Life Test Drive Current: Measurement Current: Data Set 3: 105 C, 200mA Part Number: Number of Units: Actual Case Temperature(T S ): Actual Ambient Temperature(T A ): Life Test Drive Current: Measurement Current: LED23W/PLL/827-G7DR 30 T S =54.6 C T A =52.5 C I F = 200mA I F = 200mA LED23W/PLL/827-G7DR 30 T S =84.1 C T A =82.6 C I F =200mA I F = 200mA LED23W/PLL/827-G7DR 30 T S =104.1 C T A =103.9 C I F = 200mA I F = 200mA Report No. RSZ M1 Page 5 of 14 IESNA LM Test Report
