Paper Abstract

Light emitting diodes are routinely used for general and specialized lighting tasks such as automotive headlights, streetlights, luminaires, and medical illuminators. Because of their small size and directionality, LEDs enable unique light collection and shaping techniques. This paper reviews strategies that can be used to shape light according to a desired target distribution given target uniformity and system compactness constraints imposed by each application. We address design techniques for LED secondary optics, including TIR lenses, freeform reflectors, and lens and mirror arrays.
