Abstract
An illuminator has two lines of LEDs on inwardly-directed faces of an elongate body which forms a mullion for a display cabinet. Heat conduction through the body to outer surfaces provides the durable effect of anti-sweat heating to prevent condensation in doors of the cabinet.
Claims19
An illuminator comprising:
- an elongate body having an inner surface and an outer surface;
- a plurality of light emitting diodes mounted on the inner surface of said body for product illumination;
- the elongate body including a heat transfer portion for conduction of heat from the light emitting diodes to the outer surface of the body;
- and
- the body being a structural member of a door frame for a display cabinet, said outer surface of the structural member being configured to face a door of a display cabinet to avoid a need for a heater in the structural member.

An illuminator comprising:
- an elongate body having an inner surface and an outer surface;
- engagement means for engaging a display cabinet;
- a plurality of light emitting diodes mounted on the inner surface of said body for product illumination;
- the elongate body including a heat transfer portion for conduction of heat from the light emitting diodes to the outer surface of the body;
- and
- the body including a label holder for supporting a label across the outer surface;
- a light guide for direction of light from behind the diodes to the outer surface, and the diodes being mounted on a transparent substrate.
