Abstract: A light fixture having at least one light source for generating a beam of light, a plurality of color filters are rotatable into position to intercept the light beam. The color filters are fixed to the color wheel by a central spring which has a number of radial protruding tongues for fixation of the color filters. The color filters are removable yet are secured in a correct position by radial protrusions formed between the color filters an circular outer protrusion located outward of the color filters so as to form a cavity that surrounds the color filter at both sides as well as at outward. Inward of the color filters, they are fixed by the protruding tongue that presses them down and keeps them in place. This leads to a nearly perfect fixation of each color filter, which can be exchanged if necessary.

Abstract: A light effect system includes a light source and at least one aperture element interposed between the light source and an exit lens of the system. The aperture element has at least one aperture and at least one light effect element positioned therein. The system uses an aperture element having at least two “fingers” partly surrounding each light effect element in at least 180° of the circumference. These “fingers” engage with the contour of the outer surface of the light effect element to hold the light effect element in position in the aperture, and the fingers are formed of a flexible material. Hereby, it is achieved that the locking and releasing of the light effect component can be done by push and pull in an ideal perpendicular direction to the light path. In other words, no angling, bending or twisting is necessary, so a minimum of space is required.

Abstract: Disclosed is a control device for controlling a variable-color light source, the variable-color light source comprising a plurality of individually controllable color light sources. The control device comprises a control unit for generating, responsive to an input signal indicative of a color and a brightness, respective activation signals for each of the individually controllable color light sources. The control unit is configured to generate the activation signals from the input signal and from predetermined calibration data indicative of at least one set of color values for each of the individually controllable light sources.

Abstract: A system and a method for operating an intruder deterrent system by which a smoke screen is generated in response to an intruder being detected, a smoke screen generator operatively linked to the intruder detecting. To achieve an intruder deterrent system that can operate for a longer period after interruption in the power supply, latent heat is stored in a heat storage, and smoke can be generated by transferring the latent heat from the heat storage to a liquid, which liquid is evaporated. The use of the heat storage has led to the unexpected result that the smoke generator can operate independently of power to the heating elements for a very long period.

Abstract: The present invention relates to LED bar modules where the LED groups are placed at a pixel board. The present invention further concerns a method for calibration of LEDs. It is the object of the invention to achieve a highly efficient LED bar for generating a bar of light. A further object of the invention is to store calibration data for each LED both electrically and mechanically close to the actual LED. Preferably, the main printed circuit is placed inside a heat conductive tube, where the pixel board is placed outside the heat conductive tube in a longitudinal recess, where the main printed circuit is placed inside an isolation cover. Hereby, it is achieved that the LEDs are placed on the outside of the tube in a way where heat generated from the LEDs is conducted downwards to the tube. Inside the tube, the rest of the power electronics and also the light controlling electronics are placed.

Abstract: A light fixture comprising a head, which head with at least one light source, which head is carried rotatably in a yoke, which yoke rotates in relation to a base, which bases comprises bearings for the yoke, which base has at least a power module, which power module has at least one ballast circuit, which base has at least one controller. By the base having at least one drawer in which at least the power module is located, a fast exchange of the power module in a light source in situations of changing technical specifications of the power module can be achieved very easily. This can be important in a light fixture placed high above the ground if it needs to have an electronic module exchanged.

Abstract: A light fixture having a head, a yoke and a base, the yoke having handles for carrying the light fixture. Placing the handle at the upper part of the yoke is very efficient if the light fixture is to be carried. Access to these handles is possible directly in a flight case because there is sufficient space for getting access to the handles above the yoke. In terms of small light fixtures, an individual can easily carry the light fixture by these handles and safely lift the light fixture from a flight case. In the case of very large light fixtures, two individuals can lift the fixture from both sides of a flight case and can carry the light fixture by the handles. By placing the handles as high as possible in relation to the light fixture, the light fixture can be carried in a very stable manner.

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.

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.

Hereby, it is achieved that the locking and releasing of the light effect component can be done by push and pull in an ideal perpendicular direction to the light path. In other words, no angling, bending or twisting is necessary, so a minimum of space is required.
