Lighting unit for a display shelf

摘要

A lighting unit (150) for the front edge of a display shelf is proposed. The lighting unit has a transparent or translucent elongate diffuser (160) which has elongate upper and lower edges and elongate front and rear faces. The diffuser (160) has a recessed channel (170) adjacent to extending along the elongate upper or lower edge. A lighting element (180), comprising a plurality of LED's attached to a circuit, is located in the recessed channel (170). The LED's are oriented to direct light sideways through the diffuser (160) in a direction from edge towards the other. A substantially transparent elongate cover (200) is located over the diffuser (160) and defines a gap therebetween for receiving a display graphic. The diffuser (160) scatters a portion of the light passing therethrough towards the cover (200) to back light the display graphic in the gap. The diffuser (160) also transmits a portion of the light therethrough to be emitted at the upper edge; and a portion of the light is reflected by the lighting unit (150) in a downward direction.
