Short-Term Test of the Lumen Depreciation of High-Power pcLEDs Under Tropical Condition

White pcLEDs have taken up almost a huge percentage of the industry due to their low energy consumption with adequate light output. But it is of utmost importance to look at the Useful Life of any device before it gains a huge success in the market surpassing others. It was also noted that in order to satisfy consumer needs (lower price) and due to a huge production rate, there has been a decrease in quality. Thus, it is necessary to go for the quality assessment and reliability factors of a White pcLED. Traditional testing methods require a considerable amount of time which is inconvenient at times as the technology is changing very fast. Thus, in our present work we have selected the acceleration test with the sole intention to minimize the test period of the LM80 test, which is near about minimum 6000 hours. An accelerated test method was performed by subjecting a company standard White pcLED to a high voltage stress. A total of 315 hours of testing till now was done and data was collected and compared to the LM80 standard test result.
