Problems solved by technology

However, since each light effect component occupies space in the lighting device, it is difficult to provide a lighting device with many effects
In particular, providing many beam shaping objects in a projection light setup is difficult since the beam shaping objects need to be located in the focal point (optical gate) of the optical system, and typical optical systems are only able to focus on a very limited area

Embodiment Construction

[0055] Hereinafter, concepts according to exemplary embodiments of the present invention will be explained in more detail and with reference to the accompanying drawings.

[0056] figure 1 A multi-source lighting device 100 according to the invention is schematically shown.

[0057] The multi-source lighting device 100 comprises a plurality of light sources 101 in which the lenslets 102 are arranged in a plurality of different groups 120 . The light source 101 is represented by a shaded square, where the lenslet 102 is represented by a circle surrounding the light source 101 . The main optical axis 110 is located at the center of the multi-source illumination device 100 . Each light source 101 is characterized by a radial distance 130 of the light source from the principal optical axis 110 . Each group of light sources 120 is characterized by a radial distance 140 of the group from the principal optical axis 110 . The group radial distance 140 may also include a range of r...

Abstract

The present invention provides a method for controlling a multi-source illumination arrangement in a gated optical system, wherein a plurality of light sources are divided into groups, and wherein each group is characterized by a respective radial distance from the principal optical axis . Wherein the dimming level of a group is controlled independently of the dimming levels of other groups based on said radial distance of said group from said main optical axis.

Description

technical field [0001] The present invention relates to a method for a multi-source lighting device, and in particular to a method for a multi-source lighting device in a gated light system. Background technique [0002] Luminaires that generate various light effects are increasingly used in the entertainment industry in order to generate various light effects and situational lighting related to concerts, live shows, TV shows, sporting events, or as part of architectural installations. Typically, an entertainment light fixture produces a beam of light with a beam width and divergence, and may for example be a soft / flood light fixture producing a relatively wide beam, or the entertainment light fixture may be a light beam configured to project an image onto a target surface Projection equipment. [0003] Projection luminaires generally comprise one or more light gates illuminated by the lighting device, and the projection optics system is configured to collect light passing ...
