Abstract
Abstract: Light-emitting diodes (LEDs) will play a major role in future
indoor illumination systems. In general, the generalized Lambertian pattern
is widely used as the radiation pattern of a single LED. In this letter, we
show that the illuminance distribution due to this Lambertian pattern, when
projected onto a horizontal surface such as a floor, can be well approximated
by a Gaussian function.
