Verification Method

- Run four parallel conditioning tests on separate samples as follows: 1. Salt-fog protection per IEC 60068-2-52 (NaCl 5%/35℃ Salty water sprayed for 2 hours → 40℃/93% left for 6 days 22 hours, 4cycle) 2. Sulfur protection per IEC 60068-2-43 (25℃, 75%R.H., H2S 15ppm, 504 hours) 3. High humidity protection per JESD22-A101D.01 (85℃/85%, 640mA, ON/OFF 0.5hr, 1000hr) 4. Thermal Shock per JESD22-A106B.02 (-45~+125℃ / 15min / 500cycles) - Measure and record the Forward Voltage (Vf) and Lumen (lm) values of the LEDs before and after each conditioning test. - Calculate maintenance by comparing the average of the values of the Forward Voltage (Vf) and Lumen (lm) measured before and after each conditioning test as follows: Measured value after conditioning / Measured value before conditioning X 100 = xxx % The worst case Forward Voltage (Vf) and Lumen (lm) of the four conditioning tests are reported in the claim.
