Embodiment Construction

[0017] The invention has been described in terms of exemplary embodiments merely intended to illustrate the principles of the invention. A person skilled in the art will be able to provide several embodiments within the scope of the claims. In the illustrated embodiments, the beams and optics shown are for illustration purposes only, rather than showing exact and precise beams and optics. Throughout the specification, reference numerals of similar elements providing similar effects have been given the same last two digits.

[0018] figure 1 A structural diagram of the projection lamp 101 according to the present invention is shown. The luminaire comprises a light source module 103 , a projection system 105 , a beam shaping object 107 and a controller 109 .

[0019] The light source module 103 includes at least one LED 111 that generates at least one source light beam 113 (shown as a dashed line) propagating along a main optical axis 115 (shown as a dashed arrow). In the il...

Abstract

The present invention relates to a projecting light fixture comprising at least one LED generating light beam and a projecting system positioned configured to project the light beam along an optical axis. A beam shaping object is arranged between the LED and the projecting system and comprises a least two different beam shaping patterns, which can be arranged in the source light beam upon rotationof the beam shaping object in relation to the light beam. An actuator is configured to continuously rotate the beam shaping object in relation to the source light beam in order to alternately arrangethe beam shaping patterns in the light beam. The projecting light fixture comprises a synchronizer providing a synchronizing signal indicative of: the rotation speed and / or the angular position of the beam shaping object; the position of beam shaping patters in relation to the light beam. The controller is configured to toggle the LED between a LED on-period and a LED off-period based on the synchronizing signal.

Description

technical field [0001] The invention relates to an LED projection luminaire, wherein the light gate is illuminated by at least one LED, and wherein the projection system is configured to project light through the light gate along the main optical axis. A beam shaping object is disposed near the light gate and configured to modify the light beam. Background technique [0002] Luminaires that produce various lighting effects are increasingly used in the entertainment industry in order to produce various lighting effects and mood lighting related to concerts, live shows, TV shows, sporting events or as part of architectural installations. Typically, an entertainment luminaire produces a beam of light with a beam width and divergence, and may for example be a wall washer / flood luminaire producing a relatively wide beam, or it may be a projection luminaire configured to project an image onto a target surface. [0003] The projection luminaire includes a light gate illuminated by...
