STREET LIGHTING DEVICE WITH LEDS, AND METHOD TO MAKE THE SAME

摘要

Lighting device (10) and method comprising a support structure (13, 113) which supports one or more groups of LEDs (15) which emit relative light beams, to light a determinate surface (S). The device (10) also comprises one or more arms (16, 116, 216) disposed independent and individually directed or directable with respect to the support structure (13, 113) so that each supports at least one of the group of LEDs (15), and a plurality of optic members (21) each of which is associated at least with a relative one of the LEDS (15) and has a determinate degree of collimation, to direct in a specific and uniform manner the light emitted by the relative LED (15), in a determinate sector of the surface (S) to be illuminated.
