Abstract

In recent times, as LEDs are fast becoming the preferred light source to the conventional halogen and fluorescent-based light sources, the question about their useful life also gathering attention. Concerns about their use in safety critical areas such as airfield lighting and various other display applications is still far from addressed thanks to the lack of robust methods to determine their remaining useful life (RUL). Though the past literature extensively deals with the problem of life prediction based on reliability analysis and tracking algorithms, there could still be enough scope to find more suitable methods that can be readily implemented on-board the light fixture. Here, we present a method to predict the RUL for high power white LEDs that can be readily implemented on-board the lighting system based on lumen maintenance data and on-board sensor values.
