Calculation of spatial distribution of differently oriented LEDs

Abstract

New method for calculation of spatial light distribution of differently oriented LEDs is proposed. The main idea is combination of coordinate systems associated with these light sources. Unlike other conventional approaches, this method can be applied to the emitters with light distribution with arbitrary symmetry or without symmetry at all.
