Abstract
Official abstract text for this publication.
A power control/lighting system includes a controller to provide compatibility between a lamp ballast configured to receive a dedicated dimmer signal and a phase control dimmer. In at least one embodiment, the controller converts a phase control dimming signal into dimming information useable by a lamp ballast of a gas discharge lamp based lighting system. Additionally, in at least one embodiment, the controller also controls power factor correction of the power control/lighting system. In at least one embodiment, the controller provides dimming information based on the phase control dimming signal that allows the lamp ballast to be used in conjunction with a phase control dimmer.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a first controller having an input to receive a phase control dimming signal, wherein the phase control dimming signal is a signal representing a conduction angle generated by a dimmer and the conduction angle corresponds to a phase delay of a supply input voltage to a switching power converter, and the controller is configured to: (i) convert the phase control dimming signal into dimming information and (ii) generate a power factor…
