Abstract:
A controlled-luminance lighting device, comprising at least one fluorescent light source of a linear type (5), which extends longitudinally between a reflector (1) that is formed by an elongated body having a curved surface, and a set of transverse fins (3), which are set at a distance apart from one another and which define a grill for directional control of the light emitted by said light sources,wherein the curved surface of the elongated body is curved in a longitudinal direction of the elongated body and transversely with respect to each transverse fin to define a set of tray-shaped elements each having a generally parabolic shape, and wherein each fin is provided with a double curvature both with respect to a longitudinal plane and a transverse plane perpendicular to the at least one light source.
