This invention consists in a decorative projector intended for the projection, in dark ambient conditions, of black-and-white or color signs, geometrical shapes and drawings, against a light color background. The decorative projector, in its first construction variant, according to the invention, is made up of at least one light source (1), attached to a surface (2) and powered by one of the known means also from other light sources (3) placed underneath a filter plate (4) and inside a light filter (5). Light source (1) is able to emit in a direction (a), crossing the filter plate (4), and light sources (3) emitting light on plane (A - A) which may be parallel to surface (2). The second device variant is provided with some light sources (8) placed on the generators of a cone-shaped surface (B) and which, due to their position, will send light on a projection plane (C) located outside the area made up of a light filter (10); projection plane (C) may be parallel to a surface (7). The third device variant is provided at least with a pair of light sources (D), attached to a surface (11 ), and placed between a higher filter plate (12) and a lower filter plate (13), as well as inside a light filter (14). Apart from the three above-mentioned variants, the device can also be provided in five other variants.
