Abstract: Apparatus (11) for providing an output of: (i) electromagnetic waves; (ii) sound waves; or (iii) both electromagnetic and sound waves comprises a power supply, support structure (13), control means and a plurality of transmitters (15) arranged in a linear array on said support structure (13) and in electrical contact with said control means, wherein each transmitter (15) is controllable individually and independently from other transmitters. To provide a coloured lighting effect, apparatus can comprise a first source of light of a first colour, a second source of light of a second colour, different from the first colour and a diffuser (12) for diffusing the light from the first and second sources so that the diffused light from the diffuser is perceived to have different colour, shade or hue.

Abstract: Lighting apparatus comprises (i) a deflector to deflect a light beam from a video projector in a plurality of directions, (ii) image processing means to process image information and comprising an input to receive raw image information from an image source, a processor to process the raw image information into processed image information, and an output to output processed image information to the video projector, and (iii) a controller that controls operation of the processor of the image processing means according to the status of the deflector.

Abstract: An apparatus for providing an output of at least one of electromagnetic waves and sound waves comprises a power supply, a support structure, a controller, and a plurality of transmitters arranged in a linear array on the support structure and in electrical contact with the controller. Each transmitter is controllable individually and independently from other transmitters. To provide a colored lighting effect, the apparatus can comprise a first source of light of a first color, a second source of light of a second color, different from the first color and a diffuser for diffusing the light from the first and second sources so that the diffused light from the diffuser is perceived to have a different color, shade or hue.

Abstract: In creating visual effects with lighting apparatus, a digital image projector is adapted to receive digital image information and to project an image beam, a beam director directs the image beam in a plurality of directions over the set and an image processor processes the digital image information in accordance with the direction of the beam.

Abstract: Apparatus for modifying a beam of light, comprising at least one set of blades moveable across the beam, wherein each set of blades is arranged into a first subset of blades and a second subset of blades, and wherein the respective subsets of blades are axially spaced from each other. The apparatus is particularly suitable in apparatus comprising a light source and means for directing and/or focusing the light, and may be embodied (a) in a color changer for changing the color of light in a light beam, (b) in a diaphragm for varying the aperture, and (c) in dimmer apparatus for dimming light beam.
