Aspects and embodiments disclosed herein include an illumination apparatus comprising an LED light generating device comprising groups of LEDs spatially distributed on an emission surface for the generation of light, the generated light being emitted from the emission surface of the LED light generating device through a transparent and resistant protective screen of the LED light generating device, and comprising a replaceable light shaping device mounted in front of the transparent protective screen of the LED light generating device for shaping the light emitted from the emission surface of the LED light generating device.

Illumination apparatus

Spotlight () for illuminating a film, studio, stage, event and/or theatre environment, comprising: a light space () having an optical axis () which defines a light output direction; a light source () which is disposed in the light space (); a housing () which delimits the light space () and extends in the light output direction; a main reflector () which delimits the light space, extends transversely with respect to the light output direction and, relative to the light output direction, is disposed upstream of the light source (); an output optical unit () which is disposed at a light exit side of the light space () and, relative to the light output direction, is disposed downstream of the light source () and outputs the light of the spotlight (); an auxiliary reflector (), wherein the auxiliary reflector () is disposed movably, such that it can be positioned at least at a first position between the main reflector () and the light source () or at a second position between the light source () and the output optical unit ().

Spotlight

A light source for a spotlight includes a carrier, a plurality of LEDs of different colors arranged on the carrier, a lensless collector optical system for collecting and mixing light from the LEDs, an output optical system for projecting the light from the collector optical system, and a control device for controlling the LEDs.

Spotlight LED light source

A spotlight system for illuminating a film or stage environment comprises a spotlight for generating light; and at least one optical component couplable to the spotlight for producing at least one spatial light distribution, wherein the optical component and/or the spotlight has/have a memory in which information on the spatial light distribution producible by the optical component is stored.

A light-producing assembly for a spotlight for illuminating film, studio, stage, event and/or theater surroundings comprises a carrier, on which an LED arrangement with a multiplicity of LEDs is arranged. Here, the LEDs are provided by N&#x3e;2 different color types. The assembly also comprises a line system for supplying power to the LEDs, which comprises a multiplicity of lines with N line types, wherein lines of different line types cross in crossing regions and the crossing regions lie outside of a vertical projection surface of footprint sides of the LEDs in a vertical plan view of the carrier front side. Further, the assembly comprises an optical unit coupled to the LED arrangement, said optical unit spanning the totality of the LEDs. Moreover, a spotlight comprises such a light-producing assembly.

An adjustable carrier structure for a lamp is described. Said adjustable carrier structure comprises an optical component carrier on which an optical component may be fastened, a coupling device for fastening the carrier structure on the lamp, and at least one threaded spindle. The latter comprises a first threaded spindle end that is mounted in an axially-fixed and non-rotatable manner on the optical component carrier, and is connected to the coupling device via a threaded socket that cooperates with the threaded spindle. In this case, the threaded socket is connected to the coupling device in an axially-fixed and rotatable manner. The threaded spindle extends essentially parallel to an optical axis of the adjustable carrier structure. A distance may be set between the first threaded spindle end and the coupling device by means of rotating the threaded socket. Moreover, a lamp having a carrier structure of this type is proposed.

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.

Projector

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.

Lighting system with light-emitting diode(s)

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.
