<p>This elongated lighting system comprises a section (20) capable of receiving in its interior at least: - two conductive strips (30; 31, 32) having a succession of small plates (33, 34) placed at predetermined distances so as to form pairs of electrical contacts supplying a succession of bulbs (50) arranged all along the elongated system between two adjacent contacts, - a reflective strip (40) of parabolic cross-section, arranged inside the section in the length direction of the latter, the focus of which strip is arranged in the vicinity of the centre of the bulbs, so as to constitute a linear reflector distributing a narrow light beam all along the elongated system, and - at least one diffusion grille (60; 65, 66) which can direct and reflect the light beam in a preferential direction. The invention also extends to the use of a plurality of elongated systems for lighting hypermarkets (supermarkets), which systems are placed end-to-end, while arranging the grilles so as to mask the facing light sources. <IMAGE></p> |
