Abstract: An illumination device with a number of light sources arranged in at least two groups of light sources that are individually controllable. The first group of light sources (203) have light collectors (209) such as internal reflection (TIR) lenses, mixers or other lenses placed over them to collect and convert light of the light sources into a number of light source beams. The second group of light sources (205) pass light through diffusing areas (215) of a diffuser (213) in the form of a diffusion cover included in the lamp housing to diffuse the light and create a background light for the first group of light sources. The light from the first group of light sources pass through non diffusing regions (211) of the diffuser cover without the light being diffused. The second group of light sources are interleaved with the first group by the diffuser having one or several diffusion areas between non diffusion areas.
