Definitions

  • This invention relates to a device for generating lighting effects.
  • a device for generating lighting effects comprising:
  • the light source may be multiple light sources.
  • the light source may include at least one of the following group: gas discharge laser, diode laser and coloured LED.
  • the light modulating component may be multi-faceted crystal and my be formed from glass, lead crystal or polycarbonate. In such a case the surface of the light modulating component may comprise planar facets.
  • the axis of rotation of the light modulator may be offset from the light transmission axis of the light source.
  • a second light modulating component may be provided for modulating the light either before or after it passes through the first light modulating component.
  • This second light modulating component may be a diffraction grating, or may be a textured glass or acrylic, or could include both.
  • Additional optical components may be provided with the device so that it projects the lighting effect onto a wall in use, or such that it incorporates a light receiving surface as part of the device in such a case the light receiving surface may form part of the outer housing of the device.
  • an outer housing may be at least partially translucent to customise the external projection of the lighting effects.
  • a second optical modulating component may be removable so that it can be replaced by a user to produce different effects.
  • Figure 1 shows an example 1 of the invention in which a light source 8, in this case a laser diode, generates a light beam 12 which is incident upon a light modulating component 2, in this case the light modulating component is a crystal.
  • a motor 3 and support structure (10 in Figure 3) is provided to rotate the crystal 2 about an axis. This axis is, in this example, offset from that of the light transmission axis of the light source. In this way the range over which the optical effects can be seen is increased.
  • Figure 1 indicates a single light source 8, in use, multiple light sources may be used (see Figure 3).
  • FIGS 2 and 3 illustrate a particular example of the invention which incorporates a tubular outer housing 5, which acts as the light receiving surface 5 discussed above, with hemispheres located at either end.
  • a three legged base unit 6 incorporates light sources 8 and the mechanism 10 for supporting and motor for rotating 3 a light modulator 2, which is, in this case, a crystal 2 having multiple planar facets.
  • Light from the light sources 8 passes through the crystal 2 and is diffracted in a multitude of directions to create an aesthetically pleasing effect. As discussed above, this light may also be passed through a sequence of additional modulating components 4 before being projected onto the housing 5 of the device 1 or, if there is no housing 5, onto a screen or a room wall (not shown).
  • the light sources will generally be commercially available laser diodes 8, however, since this would severely restrict the colours that could be used, additional, if weaker, light sources 9 of differing colours may be utilised to enhance the lighting effects.
  • Suitable optically transmissive materials for the composition of the crystal 2 include glass, lead crystal and polycarbonate.
  • the modulating component 2 may be formed from an amorphous lump of light transmissive material, but is preferably formed with an outside surface comprising planar facets.
  • planar facets maintains the focussed projected aspects of light rather than the more diffuse light effects that would be generated by an smooth surfaced modulating component.
  • the surface facets need not be regular, indeed a more random, and potentially more pleasing, effect will be produced if they differ in size.
  • the effects can be further customised, by an end user, by introducing a second light modulating component 4.
  • This component may be represented by optical discs 13 made from textured material into the path of the light before or after the crystal 2. These discs 13 may be supported above the crystal 2 by a structure 15 attached to the base unit 6.
  • the housing 5 further provides a structure to contain a selection of crumpled film, which may be holographic to act as a alternative second light modulating component 4, to modify the paths of light and further enhance the effects seen in the localised unit 1.
  • the device can be transformed from a localised light display unit 1 into a projection unit for a room by the removal of the translucent housing unit 5.
  • the translucence provides a light receiving surface 5 for the projection such that the consumer can appreciate the localised effects of the lighting.
  • the shape of this housing 5 may be altered (e.g. to that of a cube, a sphere or a pyramid) such that an alternative effect can be seen.
  • the housing 5 may be removed altogether such that the light effects are projected onto the walls and ceiling of the surrounding room, or onto a screen such that a wider audience may appreciate the effects.
  • a combination of these embodiments can be provided in a further embodiment where a housing is provided but the translucence does not extend over the entire surface of the housing, sections remain transparent. If a region (for example the region furthest from the light source) is clear and transparent then this will not act as a receiving surface and the lighting effects will pass through unhindered to be projected onto a neighbouring surface (for example a ceiling).
