Illuminating device, especially for an automotive vehicle. It comprises a combination of means essentially composed of: a) substantially perpendicular to the LEDs (5), in front of the illuminating face of the LEDs, a system comprising opaque parallel plates (1, 2) at least one of the faces of which is a light colour, preferably a white colour, •at least two of said parallel plates defining a channel at the bottom of which said LEDs are distributed, and •said wall-forming plates being arranged substantially perpendicular to the midplane of said PCB so as to channel the light emitted by said LEDs, and •the at least one light- or white-coloured face of said plates being turned towards the interior of said channel; and (b) near the frontal end of said channel, level with said end or preferably upstream of said end, a substantially planar reflector (7), and downstream from the latter, in the direction of light emission/transmission in operation, a semi-transparent screen (8) substantially parallel to said reflector, comprising, on at least one of its two main faces, elements promoting the dispersion of the incident light.
