A lighting module (10) for mounting onto a C-shaped rail (R) having a bottom wall (R1) and electrical lines (W) extending along the rail (R) includes a light source board (12) having a first face (12a) carrying one or more light radiation sources (14) and a second face (12b) carrying electrical contacts (18, 180) to supply the light radiation source or sources (14) from the electrical lines (W) of the rail. A channel-shaped housing (16), arranged in a position enveloping the board (12), has a web wall (16a) for emitting the light radiation and two opposed side walls (16b) each facing one of the longitudinal edges (120) of the board. Next a pair of opposed guide members (20) is provided, each extending along one of the longitudinal edges (120) of the board (12), in a position facing a corresponding side wall (16b) of the housing. Each of the guide members (20) and the corresponding side wall (16b) of the housing (16) have complementary, mutually cooperating, ramp-like surfaces (200, 1600) to retain the light source board (12) within the housing (16). Elastic members such as springs (30) urge the board (12) away from the web wall (16a) of the housing (16), whereby the complementary ramp-like surfaces are elastically urged against each other. |
