Abstract: A lighting system for a commercial display case. The display case includes a plurality of mullions disposed in a vertical orientation between doors of the display case. A plurality of light emitting diodes are disposed in a linear array on each of the mullions. A reflector system is mounted proximate to the light emitting diodes. In one embodiment, the mullion cover and reflector system are formed as an integral assembly. In another embodiment, the mullion cover and reflector system are formed separately, and the mullion cover includes recesses or other mounting features, and the reflector system is coupled to the recesses in the mullion cover. The reflective system is preferably designed to have a series of reflector surfaces disposed about one or more of the light emitting diodes to optimize light dispersal.

Abstract: A control system for an illuminated display case. The display case includes a sensor that may be used as a switch or as a controller to adjust the power being provided to the light sources in the display case. The sensor may sense motion, or temperature, or ambient light. A timer may also be used to control power.

Abstract: A door for a refrigerator display case is provided. The door includes a glass panel having a surface coated with a low-emissivity soft coating. A refrigerator display case is also provided. The display case has a refrigerated enclosure and a door with three glass panels. The middle glass panel is coated with a low-emissivity soft coating.
