Abstract: The present invention relates to a light source module comprising a light source, which light source module comprises cooling means for cooling the light source base, which light source module further comprises a dechroic reflector, where at least one heat sink surrounds the dechroic reflector. The object of the present invention is to reduce the temperature at the lamp base to increase the lifetime of a lamp. This can be achieved by a light source module that comprises at least a first heat sink, which first heat sink comprises a number of dishes, which dishes are formed to achieve air gabs there between, which dishes comprises at least one opening for the dechroic reflector, which dishes are placed radially around the dechroic reflector, which air gabs between the dishes are directed mostly perpendicularly to a centre axis of the light source module.

Abstract: The present invention relates to moving head projectors comprising a base, to which base a yoke is rotationally connected, which yoke is rotationally connected to a head, which head comprises a light source placed partly inside reflective means, which reflective means forms a light beam, which light beam passes through light forming means, which light beam furthermore passes through at least one lens before the light beam leaves the projector. The object of the invention is to achieve a primarily closed moving head projector, where air from the outside is prevented from entering the inner volumes of the projector. Furthermore, the object is to prevent the use of blowing means. Cooling of all optical and electrical components in the moving head projector can take place by means of natural heat convection and heat radiation. Thus, the moving head projector can operate without active cooling means e.g. without blowing means. This automatically leads to a very low projector noise level.

Abstract: An adaptor (8) for an axle where the axle defines the centre of rotation for transmission of the rotational movement to at least one access or attachment point (6), which is eccentric with the axis of rotation, where the adaptor (8) is disc-shape with an outer perimeter (7) and an inner perimeter (9), where the inner perimeter (9) has a shape which fits the axle, and furthermore where the adaptor (8) includes securing means for securing the adaptor (8) to the axle. This adaptor (8) is distinctive by a cut-out (10) connects the inner perimeter (9) with the outer perimeter (7), and the securing means consist of a shank portion (15) and a tread portion (14) where the shank portion (15) is larger than the tread portion (14). Hereby reducing the permanent deformation of the adaptor (8) as well as the axle as the shank portion (15) will provide most of the elasticity for the clamping force rendering it possible to transmit torque as well as reduce angle deformation.

Abstract: A production light comprising a housing (1) with a synchronous driving mechanism with at least two rollers (2,4) where a film/band (6) of gels (8) is wound and taut between the rollers (2,4) so the aperture (10) of the production light is covered by the film/band (6), characterized in that the film/band (6) comprises of a plurality of separate sections of gels (8) where the gels (8) are attached to the film/band (6) by fastening means in such a way that each section of gel (8) is easily mounted or remounted onto the film/band (6).

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, has a light changer, and a controller for controlling at least the lamp and the 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. This can be achieved with a housing with an outer casing which has at least one diaphragm covering at least one downwardly directed opening which is open towards the surrounding environment, the diaphragm being permeable for moisture for transmission from the inside of the housing to the outside, but is water-tight inward from the outside. Even in a situation where the apparatus is completely overflowed, the diaphragm prevents water penetrating from the outside.

Abstract: The present invention concerns a braking system for electric step motors, which step motors operate in conjunction with a light assembly comprising a moving head for pan or tilt of the light assembly or operating in the lamp for moving internal optical components, which step motors during operation are connected to driving means. It is the scope of the invention to reduce the speed of movement of moving head light fixtures during a power down. This can be achieved if the step motors are connected through switches, which switches in a first position during operation connect the driving means to the step motors, where at a power down, the switches change to a second position, in which second position the switches establish a current path through at least one motor winding. It is hereby achieved that all movements after power down of the moving head as well as internal movement take place very slowly and without generating noise.

Abstract: Lighting apparatus includes an effect wheel which is mounted on a rotation mechanism. The rotation mechanism is mounted on a mechanism which moves the effect wheel from a position outside of the light path to a position in which the effect wheel intersects the light path to provide a continuous wheel effect. The translation mechanism can move the effect wheel between positions in which the effect wheel crosses the light path in a horizontal direction and in a vertical direction, respectively. The apparatus allows a continuous wheel effect to be added to a multi-purpose luminaire and also allows the direction of travel of the continuous wheel effect across the illuminated field to be continuously varied.

Abstract: Units for projection of profiled images and for floodlighting suffer from a tradeoff between the quality of the illuminated field and efficiency. The hue, saturation, and intensity must be continuously controllable, and the quality of the illuminated field must be even. According to the invention the optical components have been refined according to a general principle which enables the use of efficient elliptical reflectors without a reduction in quality for both purposes. Each color is controlled by relatively moveable filters having a comblike structure in which the design of the individual teeth compensates for the interaction of the many variables. The intensity is controlled by mechanical dimmers which are designed according to the same principles. This construction will also improve the quality of condenser type projection systems.

Abstract: A light effects projector includes a light source and effect wheels interposed between the light source and an exit aperture of the projector. A gobo wheel includes a plurality of apertures and gobo holders containing gobos. The gobo wheel is adapted to rotate so as to place a gobo, which is retained in one of the holders, within the light path from the light source. The gobo holders of the gobo wheel are removably secured to the gobo wheel by a spring retainer that engages flange portions of a gobo holder. The projector further includes a cooling system to cool the gobos during operation. Additionally, the projector includes an effects wheel that provides a “frost effect” portion to variably distort light from the projector.

Abstract: For installing a fiber optic cable in a lighting unit for illumination purposes it is suitable to insert the end of the fiber bundle to a position where the end of the bundle is illuminated by the full cross section of a conical light beam, whereby it is also possible to operate with bundles of different diameters. For this purpose, the invention provides for a technique enabling a standard cable holder to be used in a highly qualified manner for different cables, with both a firm fixation of the cable end and a high finish thereof. A very accurate positioning of the cable end in the light beam is achievable without particularly high accuracy requirements in the adaptation of the holder to the specific diameter of the cable.
