Abstract
An enclosure or display cabinet for displaying heated objects (such as a food display module or container) using heat-sensitive lighting is disclosed herein. The heat-sensitive lighting may be, for example, an LED lighting unit. LED lighting is inefficient and tends to degrade or fail when operating at higher temperatures. However, LED lighting may be preferred as it is typically more energy efficient than other lighting options (such as incandescent bulbs). The lighting unit includes a thermally insulated space, shelf, or gap for housing the lighting and a system for reducing heat generated by the display or the lighting unit.
Claims8
A food display container environment, comprising:
- an enclosure having a top and at least two walls defining an interior space;
- a canopy within the enclosure and separated from the top by a gap;
- a support surface in a heated space below the canopy, which is adapted to support objects;
- a display side having an opening in the display side through which objects may be displayed to and retrieved by a user;
- a heat-sensitive light source comprising a light-generating element positioned to direct light into an area beneath the canopy;
- and
- a heat sink coupled to the light source and positioned at least partially in the gap between the canopy and the top;
- wherein a fan is positioned to circulate air from a vent on a back side of the container on an opposite side of the container from the opening, across a surface of the heat sink, and out from the gap through an exhaust vent on the opposite side of the container from the opening.
