Abstract: The equipment (1) consists of a preferably metallic support (2) fixed under a ceiling or similar structure and including two longitudinal grooves (6) in which electrical conductors (71, 72, 73) extend longitudinally for powering light fittings. The light fitting (9) to be suspended and powered is fixed to or suspended from a removable mounting plate (5), provided with means (4) for attaching to the support (2), and capable of being attached to or detached from the support (2) from the ground using a pole (12) equipped with an end piece (12a) that complements a hollow part (11) of the mounting plate (5). The mounting plate (5) includes an adapter (8) electrically connected to the light fitting (9) and interacting with the electrical supply conductors (71, 72, 73) such that the attachment or detachment of the plate (5) is accompanied, respectively, by an electrical connection or disconnection of the adapter (8).

Abstract: This display shelving device is formed from a panel with multiple interlocking metal strip sections installed and fixed against a plane wall or special supporting structures, and comprising longitudinal recesses in the strip sections and/or at the junction of these sections. Slats made of insulating synthetic material are mounted in the recesses of the strip sections and include longitudinal slots within which power supply electrical conductors run longitudinally. The latter supply lighting units by means of detachable adaptors retained in the recesses, and of electrical links with the lighting units. Support brackets are mounted in the recesses in order to support detachable trays on the underside of which are fixed the lighting units. Application: presentation of articles (A) with lighting on retail or display premises.
