Abstract

In the contribution we discuss the relationship between etendue and luminous flux of gobo projectors and its implications on illumination design and system architecture. On the basis of a given projector specification, a suitable LED type can be chosen and the number of needed LEDs and the necessary system etendue can be calculated. In a next step, we show how to design a suitable illumination system with primary and secondary optics and possibly including a homogenizer. Furthermore, implications for the design of the projection lens are discussed.
