Filed: 17th January 2011

This invention relates to improvements in methods and apparatus to power light sources, and in particular but not exclusively, relates to a highly efficient and robust method and apparatus to dim or otherwise adjust brightness or regulate the power to light sources such as Light Emitting Diodes (LEDs), Organic Light Emitting Diodes (OLEDs) and other solid-state light source loads

Claim 1: A hybrid power control system for providing dynamic power control to illumination systems comprising:

  • A power source to supply any one of a range of AC or DC voltages;
  • A light emitting device
  • One or more switch mode power supplies incorporating one or more linear and switch mode regulator circuits combined to dynamically control current, voltage and power to the illumination system
  • A microprocessor or other integrated circuit device to receive and send control information in order to regulate the power to the light emitting device
  • One or more output drive stage(s) capable of delivering a wide dynamic current range, channel bonding and protection circuitry compatible with standard or common anode illumination systems.
