  • Patent number: 9995463
    Abstract: The present invention relates to an illumination device comprising a number of light sources arranged in at least a first group of light sources and in a second group of light sources, where said first group of light sources and said second group of light sources are individually controllable. Optical means collect light from the first and second group of light sources and convert the collected light into a number of first and second light beams. The illumination device comprises further zoom adapted to change the beam diverges and/or width of respectively the first and second light beams and rotating means adapted to change the refraction of the light source beam in relation to a primary optical axis.

  • Patent number: 9109788
    Abstract: The present invention relates to a moving head light fixture comprising: a base; a yoke connected to and rotatable relative to the base; a head connected to and rotatable relative to the yoke where the head comprises at least one light source generating a light. The yoke and the base are connected through a rotating base-yoke mechanism comprising a main shaft, a hollow shaft surrounding the main shaft and at least one bearing separating the main shaft and a the hollow shaft. The main shaft has increasing cross sectional dimensions and comprises a first annular flange located a distance from the part of the main shaft having the largest cross sectional dimension and in that the cross sectional dimension of the first annular flange is smaller than the largest cross sectional dimension of the main shaft.

  • Patent number: 8944640
    Abstract: The present invention relates to main reflector and cooling system where a light source has been arranged in a main reflector and where cooling air is provided to the light source. The reflector and cooling system comprises a retro reflector arrange outside and facing the main reflector and the retro reflector comprises air inlets for providing cooling air towards the light source and air outlets for dissipating heated cooling air from the light source. The present invention relates also to a retro reflector for a reflector and cooling system.

  • Patent number: 8474986
    Abstract: A drive, primarily for an optical light forming device, which light forming device can be used in a projector, which light forming device comprises an at least partly open area for light, where at least two light forming devices cooperate in a light path for forming the light, which light forming devices are rotated around a common axis in and out of the light path. To achieve opposite synchronous movement of light forming means, the light forming devices are rotated equal in opposite directions around the common axis by a common motor. Hereby, it can be achieved that the two light forming devices are rotated synchronously, but opposite in relation to each other. The opposite synchronous movement is very important if the light fainting devices are part of a modern computer controlled projector using step motors.

  • Patent number: 7789533
    Abstract: A light fixture comprising a lamp assembly including a socket and a light source extending along a light fixture axial direction from one side of the socket. The light source is placed in a reflector such that light emitted by the light source is reflected by the reflector in the axial direction. The socket is supported by an inner ring which is supported by a middle ring and the middle ring is supporting by an outer ring. The inner ring is tiltable about a first axis that is orthogonal to the axial direction for tilting the light source, the middle ring is tiltable about a second axis that is orthogonal to both the axial direction and the first axis for tilting the inner ring, and the middle ring being movable with respect to the outer ring in the axial direction.

  • Publication number: 20090268467
    Abstract: A lamp adjustment arrangement in a light fixture, whereby a lamp socket is adjustable from the backside of a reflector by screwing in one or more directions. To perform effective independent adjustment of a light source in relation to a reflector, the lamp socket is adjustable in three directions by independent adjusting mechanisms, where a first adjustment in a first X direction is performed by first tilting an inner ring by a first screwing mechanism, where a second adjustment in a second Y direction is performed by tilting a second middle ring by a second screwing mechanism, and where a third adjustment is performed by a linear translation of a third outer ring in relation to a surrounding frame by a third screwing mechanism.
