Abstract

A lighting device with a variable pitch, comprising: a raceway (1) having an elongated U-shaped cross section, internally provided with guides (4) adapted to retain boards (5), each of said boards carrying a plurality of LEDs (6) and to allow a longitudinal translation of said boards along the raceway, a pair of electrically conductive strips (3) being internally provided on the base of said raceway (1), said boards further providing for a pair of electrical contacts (10a) each corresponding to one of said conductive strips (3), whereby an electrical connection is established between each of said pair of strips and each of said pair of contacts at any locations of said boards (5) along said raceway.
