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: Beam steering apparatus comprising an apparatus body and means in the body for generating a beam. First and second rotatable reflectors are provided for deflecting the beam in different directions, the beam being deflectable by the first reflector onto the second reflector so as to deflect the beam substantially in any direction. The apparatus is further provided with a first motor for rotating one of the reflectors and for driving a first input to a gearbox. A second motor is provided for driving a second input to the gearbox, the gearbox having an output for rotating the other reflector. The first and second motors are housed in the body. The gearbox output rotates the second reflector via a drive belt. The rotation of the first reflector induces rotation of the second reflector. The gearbox inputs and output are arranged to compensate for the induced rotation such that rotation of the second reflector by the second motor is unaffected by any rotation of the first reflector.

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.
