Abstract: A light assembly (10) is disclosed which includes an electric cord (11) coupled to a coupler (12) having a downwardly depending (13) to which a mating fastener (14) is coupled. The combination of the nipple and fastener constitutes a first shade mount. The light assembly also includes a mounting arm (17) extending from the coupler and a light socket assembly (18) coupled to the lower end of the mounting arm. The light socket assembly includes a light socket (19) having an externally threaded portion (21), a conventional light bulb (22), and a second shade mount in the form of an annular support plate (23). The support plate has an opening (24) therein with threads configured to threadably mate with the externally threaded portion of the light socket. A light shade or diffusor may be mounted at an elevated position through the nipple and fastener or at a lower position through the support plate and threaded portion of the light socket assembly.

Abstract: A shelf lighting system (60) is disclosed which includes a single upright rail (61). The upright rail includes an electrically conductive first member (62) and second member (63) which are electrically insulated from each other. The system also includes an electrically conductive shelf brackets (85) having a tongue (86) and a U-shaped mounting portion (87) configured to be mounted to the second member. The system also includes multiple corner shelves (91) having a mounting slot configured to receive the bracket tongue, a first contact (93) positioned to be in electrical contact with the tongue, and a second contact (94) positioned to be in electrical contact with the upright first member. The shelf also includes a light sources (95) having a pair of electrical conductors (96) which extend through holes passing through the shelf to the light source(s). The electrical conductors terminate with contacts (93, 94) which contact the members (62, 63).

Abstract: A shelf lighting system (10) is disclosed which includes a pair of vertical mounting rails (11) and a plurality of horizontal shelves (12) coupled to the mounting rails through mounting brackets (13). Each vertical mounting rail has a outwardly facing side wall (16), a front wall (17), and inwardly facing side step wall (18), a rear step wall (19), and an inwardly facing side bracket wall (20). As such, the inwardly facing side bracket wall is recessed behind the front wall so that it is hidden from view. Each shelf has a pair of slots (32) extending into the shelf and one or more light sources (36) positioned within the shelf to provide light. The light source(s) has a pair of electrical conductors (37) which extend through holes (38) passing through the shelf and which terminate with contacts (39). Each metal mounting bracket has an elongated horizontal tongue (41) which extends to a mounting portion (42). The tongue is sized and shaped to be received within the slot of the shelf.
