Abstract: An illuminator comprises an elongate body; and engagement means for engaging a display cabinet shelf at a front edge. Light emitting diodes are mounted on inner surfaces of the body for product illumination. The diodes are mounted for mutually divergent and at least partially inwardly-directed fields of illumination. The diodes include a top set of diodes arranged for illumination above a shelf and a bottom set of diodes for illumination below a shelf. The illuminator may further comprise a light guide for direction of light from behind the diodes to an outer surface of the body, and the diodes being mounted on a transparent substrate. The body may comprise a label holder for supporting a label across an outer surface of the body.

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.
