Abstract

In this paper, the theoretical simulation of spatial distribution Lambertian point source is performed by considering the refractive index of different material used. The refractive index contributes in changing the spatial light intensity produced at air layer of LED chip. The system required sandwich design of LED chips epitaxial layer which consist of P and N type material. At the top of the chip, Indium tin oxide (ITO) as current spreading layer has been placed. The formulation of Snell’s law, total internal reflection and Lambertian emission function contributes to analyze the effect of different refractive index toward spatial light intensity produced at air layer. The change of the total internal reflection and spatial light intensity is analyzed which respect to the change of refractive index.
