Abstract

Described herein is source sensitive optic that uses reconfigurable chip-on-board (CoB) light emitting diode (LED) arrays as light sources. In an implementation, the reconfigurable CoB LED array includes a predetermined number of LEDs that are configurable for a variety of illumination scenarios. In an implementation, the reconfigurable CoB LED array is multiple CoB LED arrays that are configured for use with the source sensitive optic as described herein. The source sensitive optic includes surface shapes that are responsive to the reconfigurable CoB LED array. The source sensitive optic is configured to provide beam profile and radiation pattern differentiation based on a CoB LED array configuration configured from the reconfigurable CoB LED. Each configurable CoB LED array configuration radiates a different beam pattern via the surface shapes due to proximity and surface shape geometries.
