Abstract

Two new illumination patterns based on LEDs are discussed. White packaged LEDs with 3mm diameter and 20^o viewing angle in three cases- a single LED source, two LEDs source and a circular ring array of LEDs- are respectively adopted in the two new illumination systems. An LED light source together with condensers and light collecting lens consists of new illumination system, the other two is optical pipe illumination system. Different shapes of the optical pipe are respectively discussed. The optical systems of the two illumination patterns are designed and optimized in ZMAX, and simulated in TracePro. Compared with conventional illumination patterns, all the two new illumination patterns achieve much better performance, even illumination, high efficiency and acquiring needed illuminating size and angle. The application of LED as light sources and these two new illumination system is discussed finally.
