Patent ID: 7911149

Claim:
An impedance controlled electronic lamp circuit, powered by a power source, for controlling a set of light emitting devices and being, comprising: at least one connector, for connecting to the power source; and for receiving a power signal; at least one filament control, associated with one of the at least one connector; a power convertor circuit; for receiving the power signal and for processing the power signal to provide a signal to power to the set of light emitting devices; and a control and monitoring circuit, including: an input current port; an input voltage plus (V+) port; an input voltage minus (V−) port; an output current port; an output voltage plus (V+) port; and an output voltage minus (V−) port; wherein the control and monitoring circuit monitors the power signal and controls the impedance of either the at least one filament control or the power convertor circuit to control the set of light emitting devices.
