    • A lighting device (10) includes a baffle (24) extending about an optical axis to surround a light source (12), and a reflector module (40) connected to the baffle. The reflector module includes a main reflector (44) having a light exit opening from which a light output of the lighting device is projected towards a target area, the optical axis passing through the opening, and a plurality of reflective surfaces adjacent to the opening for reflecting light incident thereon away from the opening. The reflector module further includes a plurality of auxiliary reflectors (60, 62) for adjusting the shape of the light output of the lighting device. Each auxiliary reflector has a reflective surface, and is moveable relative to the main reflector between a stowed position and a deployed position in which at least part of the reflective surface of the auxiliary reflector is exposed, by the opening of the main reflector, to reflect light incident thereon away from the target area.

    • The present invention relates to a framing system for shaping a light beam. The framing system comprises a 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. The shutter blades form a merged pile, where part of a first shutter blade is in placed over a part of a second shutter blade and where another part is placed below a part of a third shutter blade. A first actuator rotates at least one of said shutter blades in relation to a first rotational point and a second actuator moves the first rotational point in relation to said light beam. The present invention relates further to a method of shaping a light beam comprising the steps of rotating a shutter blade around a first rotation point using a first actuator and moving the first rotation point in relation to the light beam using a second actuator.
