Patent ID: 8427066

Claim:
A current regulator configured to control current to solid state lighting, the current regulator couplable to a power source, the current regulator comprising: a memory configured to store a plurality of current parameters: a control circuit coupled to the memory, wherein the control circuit is configured to modulate an energizing cycle time period, and wherein the control circuit is further configured to provide a substantially constant DC average current to the solid state lighting in response to a selected current parameter from the plurality of current parameters; an inductor coupled to the solid state lighting; a switch coupled to the control circuit and to either the inductor or the solid state lighting; a current sensor coupled to the switch; and a first comparator coupled to the current sensor and the control circuit, wherein the control circuit is further configured to turn the switch on to commence an energizing cycle and to turn the switch off when the first comparator indicates that an inductor current has increased to a predetermined peak level.
