    摘要: A light engine for a lighting fixture includes a bracket, with multiple mounting surfaces configured at different angles to form a substantially concave region, and a plurality of light emitting diode (LED) modules mounted to the multiple mounting surfaces to project an axis of a light beam from each of the plurality of LED modules along substantially a same illuminating plane. The light engine includes a first set of lenses with a first type of optical surface for focusing a first portion of the plurality of LED modules and a second set of lenses with a second type of optical surface, different than the first type, for focusing a second portion of the plurality of LED modules.
