Door Frame Heating Using Led Waste Heat For Cold Storage Appliances Or Rooms
Abstract: This invention can be incorporated into all domestic, commercial and industrial refrigerated spaces, which are stationary or in movable or transport vehicles. Fig. 1 shows a schematic of an exemplary application. The brand display light-guide-plate (102) on the front face, is illuminated by light emitting diodes (101) mounted on the top edge of a top door freezer. Alternatively, one or more faces, which may or may not be a door of the space is/ are edge-illuminated by LED strips. In all cases, the thermally highly-conductive backing strip (103) of the LEDs is now extended (104) to all the remaining edges of the door frame. As a result of this waste heat, frosting of the door seals is either entirely or partially prevented, eliminating or reducing the need for other door frame heating elements and their control systems, and energy is saved on a well-illuminated brand or product display unit.

Specification
CLIAMS:I Claim,
1) A new design of LED-illuminated refrigerated display units wherein:
i. the illumination is provided by light emitting diodes (LEDs) mounted on one or more edges of light guide plate(s),
ii. light guide plates form one or more vertical or horizontal display or other face(s) of the refrigerated space, which may or may not constitute the door of the space, and,
iii. the metal or thermally highly-conductive backing strip of the LEDs, which gets most of the waste heat of the LEDs, is extended to all edges of the resting face of the horizontal or vertical door frame seal to heat them, and otherwise insulated to prevent loss of heat, and,
2) Cold storage appliances or rooms incorporating the new design display units of claim 1.
