Abstract

LED luminaires are extensively used in a variety of applications. The LEDs are driven by from fraction of an ampere to nearly one ampere. LED luminaires are required to operate at high temperatures, depending on the application. High-power LED luminaires generate too much heat. If the heat generated is not dissipated away from the LED device it will affect the useful operating life and color characteristics of the luminaire. This work examines the need and rewards of detailed thermal modeling of LED luminaires. The purpose of this work is to develop a thermal model of LED luminaire such that the model represents the actual physical system. This model will be useful in reducing the experimental analysis. The scope of this work is to develop a thermal model of LED luminaire and validate it theoretically.
