Abstract:
Lighting module mounted onto a C-shaped rail having a bottom wall and electrical lines extending along the rail includes a light source board having a first face carrying one or more light radiation sources and a second face carrying electrical contacts. A channel-shaped housing envelops the board and has a web wall for emitting the light radiation and two opposed side walls each facing one of the longitudinal edges of the board. Each of a pair of opposed guide members extends along one of the longitudinal edges of the board facing a corresponding side wall of the housing. Each of the guide members and the corresponding side wall of the housing have complementary, mutually cooperating, ramp-like surfaces to retain the light source board within the housing. Elastic members urge the board away from the web wall of the housing, whereby the complementary ramp-like surfaces are elastically urged against each other.
Abstract:
A lighting assembly includes: a heat sink having a mounting surface for a light source; a light source board having said light source thereon, said light source board being arranged against said mounting surface and having an outer perimeter edge, and a drive board carrying drive circuitry for said light source, said drive board being fixed onto said heat sink with said light source board sandwiched therebetween, said drive board having an aperture with an inner edge complementary to said outer edge of said light source board, whereby said light source is left uncovered by said drive board, and wherein: said inner edge of said drive board has an inwardly protruding frame formation with said outer perimeter edge of said light source board abutting against said frame formation, and said light source board has a thickness whereby said drive board and said mounting surface have a clearance therebetween.
