LIGHT SOURCE WITH LIGHT EMITTING ARRAY AND COLLECTION OPTIC

摘要

A light system includes a plurality of light emitting elements, such as light emitting diodes, arranged in an array. One or more light emitting elements are positioned in a center region of the array. The light emitting elements in the center region have superior performance, such as luminance and/or efficiency, relative to the remainder of the light emitting elements in the array. A second region that is outside the center region, i.e., farther from the center of the array, include a second group of light emitting elements that have superior performance relative to any additional light emitting elements in the array. The array may include additional regions farther from the center of the array that include light emitting elements with lower performance. A collection optic having an optical axis is optically coupled to the array such that the optical axis is located at approximately the center of the array.
