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. Uses of the apparatus are described, for applications such as entertainment, safety, directional and speed control, such as in providing a linear sound and/or lighting effect in which the output is perceived as emanating from a substantially continuous sound and/or light source rather than from a plurality of individual sources.

Claims

1. Apparatus for providing a lighting effect, comprising:

a plurality of light sources of a first color and a plurality of light sources of a second color arranged in a line and in close proximity to one another, an elongate diffuser along a length of the apparatus, and means for independently controlling each light source, wherein the diffuser serves to diffuse the light from the plurality of sources so that the light from the diffuser is perceived as substantially homogenous and non-pixelated, said substantially homogenous and non-pixelated light changing color as the light sources are controlled.

2. Apparatus according to claim 1, wherein said means for individually controlling each light source is capable of creating static and moving lighting effects including different sections of the apparatus outputting light perceived as different colors, the whole apparatus outputting light perceived as one color and then the whole apparatus outputting light perceived as a different color, flowing a color along the apparatus, and chasing a color along the apparatus.

3. Apparatus according to claim 2, comprising at least red, green and blue light sources.

4. Apparatus according to claim 3, further comprising white light sources.

5. Apparatus according to claim 2, comprising a repeating, linear arrangement of light sources.

6. Apparatus according to claim 2, wherein the light sources and diffuser are deformably mounted together so that they can be configured into a required display shape.

7. Apparatus according to claim 2, wherein distal and proximal ends of the apparatus comprise electrical connections for connecting a plurality of apparatus together in a chain.

8. Apparatus according to claim 7, comprising electrical connections for connection of the apparatus to a power supply and/or to control electronics, whereby in the chain of a plurality of apparatus, each or a number of the apparatus can be separately connected to the power supply or power supplies.

9. Apparatus according to claim 2, wherein the light sources have variable intensities.

10. Apparatus according to claim 2, including a processor programmed to control each light source independently.

11. Apparatus according to claim 2, comprising means for connection to circuitry for control of illumination of the light sources, such as RS232 computer interface.

12. Apparatus according to claim 2, wherein the light sources are light emitting diodes.

13. Apparatus according to claim 2, comprising at least ten light sources in a linear array.

20. The method according to claim 12, comprising mounting the light sources in a linear arrangement along a length of an elongate diffuser, and outputting light along the length of the diffuser, and substantially surrounding the light sources by diffusing or non-translucent material, so that substantially no light is output from the apparatus other than via the diffuser.

21. The method according to claim 12, wherein the light sources are light emitting diodes.

22. The method according to claim 12, comprising arranging at least ten light sources in a linear array.

23. The method according to claim 12, comprising arranging at least fifty light sources in a linear array.

24. The method according to claim 12, comprising arranging at least one hundred light sources in a linear array.

17. A method of providing a lighting effect, comprising:
