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. By controlling both groups of light sources based on the same target color the dotted look of led light sources can be removed or by controlling the two groups of light sources based on two different colors light effects can be obtained. The illumination device can be included in a moving head light source with a base, a yoke connected rotatably to the base and the head connected rotatably to the head.

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 (205) have light collectors 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 (209) is arranged in an array of pixels with light output between the first group of light sources. The array of pixels can be controlled baced on a video signal. The light from each pixel can be diffused at output by passing through diffusive areas of a diffuser cover. The light source beams are not diffused since the light therefrom pass though non-diffuse regions of the diffuser. The illumination device can be included in a moving head light source with a base, a yoke connected rotably to the base and the head connected rotatably to the head. The second group of light sources (703,209) can pass light through light guides or light pipes (713a) and have an output section (717a-718b) between at least two light source beams.

An interior lamp is provided for illuminating an interior of a vehicle having a glass surface, particularly a glass roof. At least one such interior lamp is integrated in the laminated glass of the glass surface.

The lightening device (1) has a receiving element (10) that is arranged in the region of a headliner (2) with a lamp (3). A tinted windshield (12) is arranged in the direction of lamp interior. The lamp and tinted windshield are arranged in receiving element. Several lamp elements (3a-3d) are assembled in lamp.

Guide de lumiere plan comportant une face d’entree apte a recevoir de la lumiere et une face de sortie de lumiere, distante de la face d’entree et parallele a la face d’entree, et qui est la face visible du guide, la face de sortie de lumiere comportant une pluralite d’optiques de refraction (MLR), adjacentes et reparties sur toute la face de sortie de lumiere, caracterise en ce que le profil de chaque optique (MLR) comporte une premiere et une deuxieme surface de diffusion (SFC et SFT) ; la deuxieme surface (SFT) etant obtenue apres decoupe de la premiere surface (SFC). (Figure 7)

The interior light has a glass or plastic diffuser plate covering the at least one light source with optical elements (5) on its surface for scattering or deflecting the light output. At least some of the optical elements on the diffuser plate have a central, non-diffusing region (6) and a second diffusing region (7) wholly or partly enclosing it.

Eine Innenleuchte 1 hat an der ihr Leuchtmittel abdeckenden Streuscheibe (4) Optikelemente (5), die einen zentralen ersten nicht streuenden Bereich (6) und einen zweiten, diesen ganz oder teilweise umgebenden, diffus streuenden Bereich (2) aufweisen. Die Randbereiche der Optikelemente (5), die primar nicht fur die Lichtverteilung bestimmt sind, reduzieren dadurch eine Blendung der Fahrzeuginsassen. Die Ausdehnung des diffus streuenden Optikbereichs (7) ist dabei durch den Auslauf des Optikelements (5) und den ersten zentralen Bereich (6) begrenzt. Die Optikelemente (5) sind dabei kalottenformig gewolbt.
