Abstract
A lighting device includes a frame having an access panel. At least one LED is coupled to an interior edge of the frame and a light guide panel is positioned in the frame such that an edge is in communication with the LED. At least one light injection optic is coupled to the LED and the edge of the light guide panel, and is configured to direct light from the LED toward the edge of the light guide panel. At least one reflector is coupled to the LED, and is configured to direct light from the LED toward the edge of the light guide panel. At least one reflective sheet is coupled to a rear surface of the light guide panel and at least one color conversion sheet is coupled to a front surface of the light guide panel. A cover is coupled to the rear of the frame.
