Abstract
An optoelectronic circuit for receiving a variable voltage containing alternating increasing and decreasing phases, the optoelectronic circuit including a plurality of groups of light-emitting diodes and a switching device for allowing or interrupting the circulation of a current through each group, the switching device also being suitable for detecting whether said variable voltage is supplied by a dimmer.
Claims11
An optoelectronic circuit intended to receive a variable voltage containing an alternation of rising and falling phases, the optoelectronic circuit comprising a plurality of light-emitting diode assemblies and a switching device capable of allowing or of interrupting the flowing of a current in each assembly, the switching device being further capable of detecting whether said variable voltage is supplied by a dimmer.
The optoelectronic circuit of, wherein the switching device is capable of at least temporarily decreasing the input impedance of the optoelectronic circuit when a dimmer is detected.
