A light housing, such as a light box or a light source of an at least partially transparent material, characterized in that at least part of said light housing is provided with an illuminating coating. In a preferred embodiment, the coating is a dispersion with a base of cellulose, acrylate, epoxy or polyurethane, or is a foil, for example a shrink foil provided with an afterglowing pigment of an alkaline-earth metal-containing aluminate, which is doped with one or more transition metals. |
