The present invention relates to an illumination device comprising a number of light sources generating light and a number of light collecting means adapted to collect the generated light and to convert the collected light into a number of light beams that propagate along an optical axis. The light sources are arranged in a first group and second group of light sources which are individually controllable. The light collecting means and light sources are displaceable in relation to each other between a first position where the light collecting means collect light from the first group of light sources and convert the collected light into a number of first light beams, and a second position where the light collecting means collect light from the second group of light sources and convert the collected light from the second group of light sources into number of second light beams.

The present invention relates to a light controller for controlling a lighting system, where the lighting system comprises a number of light emitting devices such as controllable light fixtures, controllable light emitting visual devices and/or controllable display devices adapted to emit video content. The light controller comprises a first slide controller, a second slide controller and a locking mechanism adapted to fix the first slide controller and the second slide controller in relation to each other, such that movement of at least one of the slide controllers forces the other slide controller to perform a corresponding movement.
摘要:
An illumination device or method of generating illumination using an illumination device is described with two light sources with different spectral distribution a number of displaceable light collectors collecting light from the light sources where in one mixing position receiving light from both light sources where at least one of the light sources has two independently controllable light emitting areas and in one mixing position the collecting area collects light form the first light emitting area and substantially not from the second light emitting area. Further an unrelated illumination device with at least one Light Emitting Diode, LED and a current spreader connected to and covering a first area of a first side of the lead, spreading current in an irregular pattern and a current controller controlling current flowing through the first current spreader. The current spreader can be patterned to produce a round beam illumination or illumination in a form of a static picture or logo. A round beam illumination can better cooperate with an optical system of lenses in an illumination device. Further the current spreader can be patterned to have lower current density in the center to reduce/avoid temperature hotspot in the center and obtain a more even die temperature.

The present invention relates to an illumination device illuminating an optical gate and projecting an image of the optical gate towards a target surface. The illumination device comprises a light source module generation light, an aperture delimiting the optical gate and a projecting system adapted to image the optical gate at a target surface. The light source module comprises a number of light sources and a number of light collecting means. The light collecting means comprise a central lens aligned along and a peripheral lens at least partially surrounding the central lens. The central lens collects and converts a first part of the light from the light source images the light source between the aperture the projecting system. The peripheral lens part collects and converts a second part of said light from said light source and is adapted to concentrate said second part of said light at said aperture.

The present invention relates to a moving head light fixture, which, moving head light fixture comprises a light generating head, which head is carried in a yoke, which head is rotatable to the yoke, which yoke is rotatable to a base, which head comprises electronic circuits for LED control. The moving head comprises a first and a second end section, which first and second end sections comprise a number of light sources. Hereby it can be achieved that the moving head light fixture which is able at the same time to generate a light into different directions. By having independent control over the light sources in both directions, it is possible to control the light from an external controller independently in both directions. The light sources could be formed out of a multiple of single light sources generating light at different colors. In this way it should be possible by means of an external command to the moving head light fixture to control the color of the light as well in the front direction and also in the opposite rear direction.
