20120206064 | Hybrid Power Control System - A hybrid power control system for providing dynamic power control to illumination systems in which a power source can supply any one of a range of AC or DC voltages. 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 a 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. | 08-16-2012 |
20130214697 | POWER CONTROL SYSTEM FOR AN ILLUMINATION SYSTEM - A power control system for an illumination system has a power source to supply any one of a range of AC or DC voltages, a power conversion stage, one or more light emitting device(s) for illumination and/or wireless communication, a controller controlling an output stage to receive and send information to regulate the power and/or current to the light emitting device(s), and a programmable voltage clamping or linear regulator arrangement contained within the output stage that can be controlled to increase a dynamic dimming ratio of current and/or power through the light emitting device(s) and to enable power or current modulation for wireless optical communication of light emitting device(s). The power control system enables current and power to be provided to one or more attached light emitting device(s) with a vastly extended dynamic dimming range such that different light emitting devices can be powered using the same driver output stage(s). | 08-22-2013 |
