The lime time of LED sensor luminaire decreases due to many factors, being the heat is one of them. We develop a controller to expand the lifetime of LED sensor luminaire. By controlling the current through the LED, the temperature of PN junction of LED maintains the proper level to prevent the overheating of LED, then the lifetime can be expanded. This study measures the illumination of Maximum life span refers to a measure of the maximum amount of time one or more members of a population has been observed to survive between birth and death. This study shows the method to measure the illumination of LED, controls the amount of current flows in order to maintain the level of illumination of LED output, extend the lifetime of LED, and guarantees the minimum illumination of LEDs.
