20080198605 | Projector - Disclosed is a projector comprising a lamp and a reflector which reflects the light beams emitted by the lamp towards a light output hole of the projector. The position of the reflector and the lamp relative to each other can be modified, the distribution of the light that is output being adjustable by displacing the reflector and/or the lamp. The reflector is provided with facets which embody a reflective surface to reflect the light beams emitted by the lamp. The surface shape of said facets is designed such that the light beams generate a luminous field which has a desired light distribution and whose light beam width can be adjusted within a large range by displacing the reflector and/or the lamp. | 08-21-2008 |
20090027890 | PROJECTOR - A projector is provided. The projector comprising a projector housing in which there are arranged an illuminant holder, for holding an illuminant, a reflector that reflects the light beams emitted by the illuminant to a light exit opening of the projector housing that is covered by a transparent disk, and a convective cooling device, partially enclosing the illuminant, that produces a convection flow for dissipating the heat output by the illuminant and has a number of cooling fins combined into cooling fin packs. The cooling fins are aligned parallel to the radiating direction of the projector, and the cooling fin packs are arranged above and below the illuminant in the direction of gravity. | 01-29-2009 |
20090068877 | Apparatus for making electrical contact with luminous means in spotlights - An apparatus for making electrical contact with luminous means in spotlights, which contain a glass vessel, a luminous means base and contact pins for the power supply is provided. The apparatus comprising a luminous means holder with at least two socket pairs for accommodating the contact pins of different luminous means. The socket pairs are arranged in clamping pieces, whose mutually opposite connecting faces can be removed from one another in order to accommodate the contact pins of the luminous means and can be guided towards one another in order to make electrical contact with the contact pins of the luminous means. | 03-12-2009 |
20090073696 | Dimming Device for a Searchlight - A dimming device for a searchlight for adjusting the brightness of a light field generated by a searchlight is provided. The dimming device comprising a plurality of different screening elements, which are formed and provided to partly or completely screen the light emitted by the searchlight. The screening elements are formed by different structured masks at least partly screening the light emitted by the searchlight, which include regularly arranged opaque or partly transparent regions and transparent regions. Means each are provided for incremental adjustment of the brightness of the generated light field of the searchlight either to bring the screening elements into the region of the light emitted by the searchlight, in order to reduce the brightness of the light field generated by one brightness level, or to remove the same from the region of the light emitted by the searchlight, in order to increase the brightness of the light field generated by one brightness level. | 03-19-2009 |
20090170370 | Apparatus for Accommodating and Making Electrical Contact With a Luminous Means in a Spotlight - An apparatus for accommodating and making electrical contact with a luminous means, which contains a glass vessel, a luminous means base and contact pins for supplying power, in a spotlight, which contains a luminous means holder for accommodating the luminous means base with plug-type sockets for accommodating the contact pins of the luminous means, is provided. The luminous means holder has a device for monitoring the connection between the luminous means base and the luminous means holder. The monitoring device comprises a device for detecting the relative position of at least one part of the luminous means base in relation to the luminous means holder when the luminous means base is inserted into the luminous holder. | 07-02-2009 |
20090251905 | Retaining Bracket for Spotlights - A retaining bracket for spotlights is provided. The retaining bracket comprising bracket bearings which are arranged at the ends of the retaining bracket, for accommodating the spotlight housing and a central supporting bearing for connecting the retaining bracket to a supporting apparatus The distance of the bracket bearings from one another is capable of being adjusted in self-centering fashion. | 10-08-2009 |
20100219758 | LIGHTING DEVICE COMPRISING A PLURALITY OF CONTROLLABLE LIGHT-EMITTING DIODES - A lighting device comprising a plurality of lighting modules which include a module carrier on which a light source with a plurality of controllable light-emitting diodes emitting light of different wavelengths and arranged on a board, a temperature sensor and a module electronic are arranged. Said module electronic contains a digital circuit with a microcontroller for the local and autonomous signal processing, which actuates the LEDs in dependence on the temperature such that the brightness, color and chrominance of the light mixture composed of the LEDs emitting light of different wavelengths is constant. Said lighting modules being connected with other lighting modules or an external controller via a digital interface for transmitting the board temperature of the respective lighting module detected by means of the temperature sensor. A central master module or the external controller actuates the lighting modules such that a uniform brightness is obtained over the radiating surface. | 09-02-2010 |
20110013395 | LIGHTING SYSTEM - A lighting system with at least one LED panel is provided. Said LED panel including a plurality of similar lighting modules, said lighting modules having controllable light-emitting diodes (LEDs) and a polygonal housing frame. Said polygonal housing frame comprising a board for receiving said lighting modules. Said polygonal housing frame including a plug connector on at least one side of the housing frame for positively mechanically coupling a sliding rail connection. Said plug connector including electrical contact means integrated in said mechanical sliding rail connection. | 01-20-2011 |
