Abstract: The invention relates to a coupling member for the mechanical and electrical connection of lighting device in line and/or angled for the formation of lighting system. The coupling includes a junction body (11) having more sides and on each side mechanical connecting means (18) and an electrical end connector (16), which link up with complementary elements, both mechanical (23) and electrical (21), at the edges of each lighting device (19) to be connected. The junction body bears four sides and the electrical connector along the sides are precableable.
Abstract: This invention concerns a light diffuser for lighting equipments which is made up of a front plate (14) with holes or openings (16) distributed uniformly over all its surface, and an internal sheet (15) associated with the internal surface of the front plate and having holes of a different diameter (17, 17?, 17?) along different parts of its length and each positioned in line with an opening in the front plate. The front plate and the internal sheet may be two associated bodies or form a single integrated body.
