Abstract
A LED control circuit is disclose which comprises a silicon-controlled rectifier (SCR) configured to control a first current supplied to a LED light bulb, and a dynamic current maintenance module serially coupled to the SCR and configured to draw a second current from the SCR, the second current being inversely proportional to the first current.
Claims18
A circuit comprising:
- a silicon-controlled rectifier (SCR) configured to control a first current supplied to a light-emitting diode (LED) light bulb;
- and
- a controlled current load serially coupled to an anode or a cathode of the SCR and configured to draw a second current from the SCR, an amplitude of the second current being inversely proportional to an amplitude of the first current.
A circuit comprising:
- a silicon-controlled rectifier (SCR) configured to control a first current supplied to a light-emitting diode (LED) light bulb;
- a current measurement module configured to generate an indicating voltage proportional to an amplitude of the first current;
- and
- a controlled current load serially coupled to an anode or a cathode of the SCR and configured to draw a second current from the SCR, an amplitude of the second current being inversely proportional to the indicating voltage.
