  • 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.

  • Patent number: 7478916
    Abstract: An apparatus for illumination having a housing suited for in ground use, which contains at least one lamp which is surrounded by a reflector, a controller for controlling the lamp and light changing means. To reduce the content of moisture, air containing evaporated water is able to be released from the lamp to the surroundings and only air without moisture is allowed to enter the in-ground lamp.
