Abstract
Abstract An illuminated tray is provided for use in darkened restaurants or nightclubs. The tray has a tray housing with a peripheral rim and a flat serving surface recessed within the rim. Spaced apart LEDs are positioned on the tray rim such that the light from the LEDs, when illuminated, is visible from both above and below the tray. Spaced apart batteries for energizing the LEDs are contained within the tray housing and are positioned in a manner that is substantially symmetric with respect to the center of the tray. The tray is thus balanced along any diameter.
