Luminous false-wall device

A luminous false-wall device comprising:

• a chassis constituted by at least one profile, the chassis comprising an upper part directed toward a panel to be covered and a lower part;
• a diffusing canvas fixed on the chassis and stretched on the lower part of the chassis;
• and
• a light source placed between the panel and the canvas configured to emit light in the direction of the canvas,
• wherein the chassis is provided with means of increasing the light intensity of the light, the means of increasing the light intensity comprising a reflective surface suitable for reflecting the incident rays from the light source toward the canvas, and
• the chassis creates a shaded area on the canvas at a periphery facing the chassis, the reflective surface being configured to redirect part of the rays coming from the light source to the shaded area in order to even out a level of luminosity on an entirety of a surface of the canvas.
