Patent areas covered:

  • Lighting Fixture designs
  • Fibre optic illumination
  • Mechanical and electrical dimming
  • Non-imaging light source
  • Colour mixing from multiple sources
  • Digital projection using DMD/TFT

Claim 1: Apparatus comprising a light source, a chamber surrounding the light source, the chamber having an inner surface for scattering and/or reflecting light from the light source, and an exit port in the chamber which provides for a light output, the arrangement being such that there is no direct path for light emitted from the light source to the exit port.

The Light Source may be defined as:

  • Fluorescent light, linear and compact
  • Halogen incandescent lamps
  • Incandescent light bulbs
  • Tungsten filament lamps
  • High intensity discharge lamps, (HID)
  • Light emitting diodes (LEDs) all/different colours
  • Electro luminescent lamps
  • Radio luminescent lamps
  • Radiofrequency (RF) lamps
  • Microwave light sources
  • Laser light sources

The non-imaging properties of the SCILS patent provides the following benefits:

  • A unique ability to blend multiple LEDs into a single light source
  • Uniform light of the highest quality at any intensity level
  • Hidden lamp sources
  • Virtually glare-free light
  • No striation or prism effects
  • Cool beam temperatures even with 200W LED systems
