Abstract
The present invention relates to a framing system for delimiting a light beam. The framing system comprises a base support rotatable supporting a frame support. The frame support comprises: a number of shutter blades surrounding the light beam; a number of actuators adapted to moved the shutter blades in and out of said light beam. The framing system comprises further rotatable electric connecting means, the rotatable electric connecting enabling transferring of electric energy between said frame support and said base support during rotation of said frame support in relation to said base support. The present invention relates also to a light fixture comprising the framing system and a method of delimiting a light beam.
Claims10
A framing system for delimiting a light beam, said framing system comprising a base support rotatably supporting a frame support, said frame support comprising:
- a number of shutter blades surrounding said light beam;
- and
- a number of actuators adapted to move said shutter blades in and out of said light beam;
- wherein the framing system comprises rotatable electric connecting means, said rotatable electric connecting means enables transferring of electric energy between said frame support and said base support during rotation of said frame support in relation to said base support.
A method for delimiting a light beam using a framing system, where the framing system comprises a base support rotatably supporting a frame support, said frame support comprising:
- a number of shutter blades surrounding said light beam;
- and
- a number of actuators adapted to move said shutter blades in and out of said light beam;
- said method comprising the steps of:
- moving at least one of said shutter blades in and out of said light beam using said actuator;
- rotating said shutter blades around said light beam by rotating said frame support;
- wherein said step of rotating said shutter blade around said light beam comprises the steps of:
- rotating said frame support at least 360 degrees;
- and
- transferring electric energy between said frame support and said base support.
