LED LUMINAIRE INCLUDING A THIN PHOSPHOR LAYER APPLIED TO A REMOTE REFLECTOR

摘要

A luminaire (100) including a thin phosphor layer (118) applied to a remote reflector (108) is disclosed. In some embodiments of the luminaire, LEDs (106) illuminate and activate a thin remote phosphor coating applied to a reflective substrate. In some embodiments, the LED light source includes at least one LED with a GaN emitting layer. The LEDs can be packaged with or without a local phosphor. The thin remote phosphor (118) can include red, red/orange, yellow, green or cyan emitting phosphor so that the luminaire produces white light. The thin remote phosphor layer (118) can include two or more different color emitting phosphors. In some embodiments, the luminaire is a light fixture (300) including a diffuser lens assembly (115,116) and a pan (302) to support the fixture when mounted in a ceiling.
