摘要： The present invention relates to a light collector for an illumination device collecting light from a plurality of light sources and combing the collected light into a common light beam, where the common light beam is coupled through an optical gate. The light sources are distributed offset and around an optical axis and the light beam collector comprises a first reflector surrounding the optical axis and a second reflector surrounding the optical axis, where the first reflector reflects the sources light beams towards the second reflector and where the second reflector reflects the source light beams in a direction along the optical axis. The light beam collectors is divided into a number of reflector pairs, where each reflector pair comprises a first surface part of the first reflector and a second surface part of the second reflector, where the second surface part receives light from the corresponding first surface part of the reflector pair.

摘要： A method for controlling a multisource illumination device in gated optical system is provided. A plurality of light sources is divided into groups, and wherein each group is characterized by a respective radial distance from a primary optical axis. Therein, the dimming level of a group is controlled independently from the dimming level of other groups based on the radial distance of the group from the primary optical axis.

摘要： 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.
