Low Frost Led Light Guide Display Door For Cold Storage Appliance Or Room
Abstract: This invention can be incorporated into all domestic, commercial and industrial refrigerated spaces with display doors, which are stationary or in movable or transport vehicles. Fig. 4 shows a schematic of an exemplary application of the new LED-illuminated plates which form one or more display door(s) of the refrigerated space. The display plate (302) is comprised partially or wholly of a light guide plate and is illuminated by light emitting diodes (301) mounted on one or more edges. The LEDs are mounted in an enclosure (303) that directs their light as well as waste heat into the display plate. As a result of this heat, frosting of the door seals and of the display plate is either entirely or partially prevented. The need for door frame heating or anti-sweat heating wires or strips and their control systems is thus eliminated or reduced. Overall energy is thus saved on a well-illuminated display door unit.
