Abstract
Official abstract text for this publication.
A controller for a lamp assembly is disclosed. The controller comprises: a mains sensing unit arranged to detect a mains voltage supplied to the lamp assembly; a waveform evaluation unit coupled with the mains sensing unit and arranged to generate a light control signal based on the mains voltage waveform; a demodulation unit coupled with the mains sensing unit and arranged to demodulate a data signal modulated on the mains voltage; an arbitration unit coupled with the demodulation unit and arranged to evaluate the results of the waveform evaluation unit and the demodulation unit and to decide an operation mode; and a control unit coupled with the arbitration unit and arranged to generate a drive signal to drive a light source of the lamp assembly based on the determined light control signal or the demodulated data signal depending on the decided operation mode.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for controlling a lamp assembly, comprising the steps of: detecting a mains voltage supplied to the lamp assembly; evaluating the waveform of the mains voltage and determining a light control signal based on the mains voltage waveform; applying a demodulation process to the mains voltage to demodulate a digital data signal; deciding a control operation mode based on the result of applying a demodulation process to the mains voltage; and g…
