Abstract
A complete Accelerated Life Test on high luminosity blue LEDs is presented. The test was conducted at different temperatures, humidity and current conditions, involving a total of seven individual tests. Life models were obtained for the catastrophic failures of the tests and then a complete temperature, humidity and current model was developed,which enabled the calculation of the life of the LEDs for any of these conditions. Catastrophic failures and model parameters were consistent with earlier results using different high luminosity LEDs. Non-catastrophic failures were modelled with their corresponding luminous power loss on each test, with expected results.
