摘要： 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.

IPC分类号： H05B45/22
摘要： Disclosed herein are methods for controlling light fixtures comprising unique color light sources with independently controllable luminous flux, comprising controlling a luminous flux of each of the light sources, wherein a spectral distribution of light emitted from the light sources upon being controlled according to settings within a plurality of setting is different between settings, and a color of light emitted from the light sources is similar or identical between settings. The methods may improve color rendering where a certain color of emitted light is required, e.g., where a certain prop or costume is better illuminated with one setting compared to another setting, drawing attention to certain objects in a scene, e.g., by choosing a setting which makes a certain object stand out, and/or providing an intriguing optical effect, e.g., by shifting between settings, which makes certain objects appear to change color while others appear to keep same color.

摘要： A method of determining pose of a moving head light fixture, comprising a support structure and a rotatable structure rotatable connected to the support structure. The rotatable structure comprises at least one light source generating a light beam and a position indicating the position of the position indicator. The method comprises the steps of arranging the position indicator at at least three different positions around the axis of rotation by rotating the rotatable structure; and a step of obtaining the position of the position indicator at each of the at least three different positions. The pose of the moving head light fixture can be obtained based on the obtained positions.
