This work presents a methodology for optimizing the layout and geometry of an m Ã?â?? n\nhigh power (HP) light emitting diode (LED) luminaire. Two simulators are used to analyze an LED\nluminaire model. The first simulator uses the finite element method (FEM) to analyze the thermal\ndissipation, and the second simulator uses the ray tracing method for lighting analysis. The thermal\nand lighting analysis of the luminaire model is validated with an error of less than 10%. The goal of\nthe optimization process is to find a solution that satisfies both thermal dissipation and light efficiency.\nThe optimization goal is to keep the LED temperature at an acceptable level while still obtaining\nuniform illumination on a target plane. Even though no optical accessories or active cooling systems\nare used in the model, the results demonstrate that it is possible to obtain satisfactory results even\nwith a limited number of parameters. The optimization results show that it is possible to design\nluminaires with 4, 6 and up to 8 HP-LEDs, keeping the LED temperature at about 100 ââ??¦C. However,\nthe best uniformity on a target plane was found by the heuristic algorithm.
