| Popis: | This paper presents an improvement of the optimization methodology of luminaire built by high power light emitting diode (LED) matrix. Six parameters that modify the geometry and layout of the luminaire are evaluated through a parameter sensitivity study. The result indicates that five parameters have an equally distributed sensitivity index, while one parameter presents an index with less than 1% influence. The metrics defined in a previous study to evaluate the results of thermal analysis and lighting analysis are enhanced. Five new illuminance evaluation profiles on a target plane are defined, and a new metric for light evaluation is created, just as a new thermal evaluation function is selected. |
