The invention relates to a lighting device, in particular for a motor vehicle, comprising LEDs secured to a printed circuit board (PCB). The device is characterised in that a system is positioned substantially perpendicularly to the LEDs (5) in front of the illuminating face of the LED, said system comprising parallel opaque plates (1, 2), of which at least one of the faces is a light colour, preferably white. According to the invention, at least two of the aforementioned parallel plates rest on the PCB (4) and/or on the periphery thereof, on each side of at least one LED borne by said PCB, such as to define a channel having a base in which the LEDs are distributed; the wall-forming plates are deployed substantially perpendicularly to the mid-plane of the PCB such as to channel the light emitted by the LEDs, which leaves the device on the side of the plates opposite the above-mentioned side resting on or around the PCB; and the at least one light-coloured or white face of the plates faces into the channel.
