Design of an anti-glare projection lamp based on a double-reflector

摘要

A new optical design of a confocal double-reflector for white LED lighting has been presented and demonstrated. To perform uniform illumination with specific projection angle, the reflector is designed to equip multiple segments, and each segment contains a curve surface to control the projection angle. In addition, the anti-glare design with double-reflector prevents direct view of the LED.
