Three-Dimensional Modeling and Comparative Photometric Analysis of LED Lamp with Polycarbonate, Polymethyl Methacrylate and Acrylic Diffuser Materials

Building and study of a three-dimensional model of an optical system of LED lamp for indoor lighting and photometric analysis by using Monte Carlo raytracing method of the modelled optical system with a diffuser made of various transmissive materials, transmittance and scattering angle is done in this paper. The results for the calculated number of ray reaction, zonal luminous fluxes, beam angle, light distribution curves and efficiency of the LED lamp optical system for different materials of the modeled diffuser are presented. A conclusion in terms of the realized photometric indicators and achieved total efficiency of the LED lamp optical system with various diffuser materials is done.
