Abstract
Light engines for inclusion in luminaires. Some embodiments of the light engine include a heat sink, a reflector, and light emitting diodes. Some embodiments of the heat sink include perforations. The reflector includes a reflective surface that extends around at least a portion of the light emitting diodes. In some embodiments, a portion of the reflector is sandwiched between the light emitting diodes and the heat sink. In some embodiments, an end of the reflector terminates above the light emitting diodes to reduce the concentration of light directly above the light emitting diodes but rather distribute the light outwardly from the luminaire.
