Abstract
In order to develop a simple ray tracing model for simulating the radiation pattern of a LED, the propagation of a ray within the LED capsule was systematically evaluated by considering refraction and reflection from the capsule-air interface, multiple reflection within the capsule, and total internal reflection at the boundary. It was found that concentric ring shapes on the radiation pattern was formed by the rays multiple-reflected from the capsule surface, and that the strength of these rays were decreased rapidly as the number of multiple reflection is increased.
