LED PIXEL DEVICE WITH DYNAMIC DIFFUSER EFFECTS

摘要

The present invention relates to a LED pixel device comprising: a plurality of individual controllable LED pixels arranged in an array; a LED pixel controller adapted to control said number of individual controllable LED pixels; an optical diffuser arranged in front of at least a part of said LED pixels, said optical diffuser receive light from said LED pixels and diffuses the received light; at least one diffuser actuator adapted to moved said LED pixels and said optical diffuser in relation to each other, diffuser controller adapted to control the diffuser actuator; wherein the optical diffuser and the LED pixels can be moved between a non-mixing position and a mixing position, where in said non-mixing position the light emitted by the LED pixels are separated when hitting the optical diffuser and where in the mixing position the light emitted by said LED pixels are at least partial overlapping when hitting said optical diffuser. The present invention relates also to an optical diffuse mountable at a LED pixel device and movable in relation the LED pixel device.
