LED luminaire for display cases

摘要

A lighting luminaire for use in a refrigerated display case includes an LED mounting portion comprising a plurality of light emitting diodes (“LEDs”) mounted thereon, a reflector, and a lens. The LED mounting portion and reflector are sized and arranged to form a reflective cavity for diffusing and directing light from the plurality of LEDs through the lens and out of the luminaire. The LED mounting portion and reflector are either attached to each other as separate components or are integrally formed. The lens is held in place in the luminaire between the LED mounting portion and the reflector or is mounted directly on the LED mounting portion over the plurality of LEDs. The LED mounting portion and/or reflector have a reflective surface for reflecting light emitted by the LEDs. Methods for retrofitting an existing luminaire in a refrigerated display with an LED luminaire are also provided.
