Reflectors for Multiple Applications Based on Flux Compensation Method
The reflector of one surface for Light-emitting diode (LED) is designed based on flux compensation method. It is easier to be fabricated compared with freeform lens. Moreover, the reflector can effectively reduce material absorption loss. This design method is simple and other researchers can understand and repeat more simply. The designed reflector also has a small exit angle for uniform illumination. It has high illuminance uniformity and flux efficiency, which are more than 90% and 95%, respectively. Reflectors designed here can be used in optical signal coupling, display cabinets, and other optical transmission applications.
