The Illumination control system for Light Emitters (ICSLE) provides a means for controlling an LED light fixture that contains an optical cover and an optical sensor which is able to detect colour and intensity to modulate the light emitters to create a specific colour point. The light emitters may be defined as a traditional light source or LEDs as well as a hybrid combination of traditional and LED light sources. The precise colour control enables variable CCT lighting fixtures to be produced with very high colour consistency between lighting fixtures.

  • The advantageous properties of
    the ICSLE patent are:
  •  A unique method to control the
    colour point of lighting fixtures
  •  Cover the use of traditional, LED
    and a combination of light sources
  •  The use of heat sinks including
    active technology 
  •  A variety of current control technologies such as DC, PAM, PWM, PFC 
  •  Variable CCT and CRI setting and accurate colour consistency
  •  The use of fluorescent tubes and LEDs combined
