Investigating the Influence of Environmental and Design Parameters on the Thermal Regime of a LED Lamp

Abstract

The increase of the LED’s temperature above a certain threshold decreases significantly their live expectancy. Therefore, it is important to investigate LEDs’ thermal regime during the design process in different conditions for exploitation. The influence of the construction and the environment parameters on the thermal regime of LED lamp was investigated in this paper. The study was done with a specially developed software, based on a model, describing the thermal regime of LED lamps. Next, a methodology for the research has been developed and a simulation study was carried out. The results of this investigation are represented graphically.
