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. Hereby, it is achieved that most of the infrared light, which is radiated in the direction of the dechroic reflector is absorbed in the dishes of the heat sink, and because the direction of the dishes is perpendicular to the main axis of the lamp module, the dishes conduct the heat radially towards the outer surface of the dishes.

Light source module

A moving-head device () comprises afoot () and ahead () that is movably arranged with respect to the foot (). The head () comprises a first rotation member () that is rotatable with respect to the foot () about a first rotation axis (), and a second rotation member () that is rotatable with respect to the first rotation member () about a second rotation axis (). A lamp () is arranged inside the first rotation member (), while directing means () are provided for directing light originating from the lamp () to an external light outlet (). If the first rotation axis () extends in a vertical portion of the lamp () constituting an upper side () does not change during operation of the moving-head device (), so that said portion may be easily cooled continuously.

Moving-head device comprising a lamp

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.

Lighting apparatus

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.

Optical system for creating colored fields of light and components therefor

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 &ldquo;frost effect&rdquo; portion to variably distort light from the projector.

Light effects system

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.
