A lighting device (10) includes a tray-like housing (12) with a base wall (12a), at least one light radiation source (14), of the LED type for example, on the base wall (12a) of the housing (12), having electrical contact pads (14a) in an opposite position from the base wall (12a) of the housing (12), and a circuit board (16) on the base wall (12a) of the housing (12) with electrically conductive lines (160) extending on the face of the board opposite from the base wall (12a) of the housing (12), with respective electrical contact pads (16a) placed in positions facing the electrical contact pads (14a) of the light radiation source or sources (14). At least one optical element (18), such as a reflector, is provided, with a light input (18a) to collect light radiation at the light radiation source or sources (14) and one or more light outputs (18b) to project light radiation from the lighting device (10). The optical element (18) has an electrically non-conductive base wall (180) which urges the light radiation source or sources (14) and the circuit board (16) toward the base wall (12a) of the housing (12), and carries electrical contacts (1800) to bridge the contact pads (14a, 16a) of the light radiation source or sources (14) and the circuit board (16). |
