Patent number: 10724696Abstract: 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 rotation of 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 arrange the 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. Where a controller is configured to toggle the LED between a LED on-period and a LED off-period based on the synchronizing signal.Type: GrantFiled: September 21, 2016Date of Patent: July 28, 2020Assignee: Harman Professional Denmark ApSInventor: Niels Jørgen Rasmussen
