A Monte Carlo ray tracing method is applied to analyze the light extraction characteristics of AlGaInP based LED
with various shapes of surface texture. Regular, periodic arranged structures were fabricated on p-side-up AlGaInP LEDs
through dry etching. The dimension of the structures was optimized by Monte Carlo ray tracing simulation. Compared to
the conventional LED, it significantly improved the performance of the chip, the light extraction efficiency was
increased more than 11.5%. the enhancement is attributed to the appearance of an additional escape cone for light
extraction enabled by surface texture. And it is also easy to extend the Monte Carlo ray tracing method to develop
LED lamps, consisting a reflector dish and an epoxy lens.
