ELECTRONIC CONTROL TO REGULATE POWER FOR SOLID-STATE LIGHTING AND METHODS THEREOF

A regulator device (10) that includes a plurality of switches (14a-14e) and a control circuit (12, 13) that controls the plurality of switches (14a-14e) is described. The plurality of switches (14a-14e) selectively couple respective strings of the light emitters (18a-18e) in series to the input powe...

Summary:A regulator device (10) that includes a plurality of switches (14a-14e) and a control circuit (12, 13) that controls the plurality of switches (14a-14e) is described. The plurality of switches (14a-14e) selectively couple respective strings of the light emitters (18a-18e) in series to the input power to emit light when deactivated. The control circuit may deactivate a number of the switches (14a-14e) to couple the respective light emitters (18a-18e) to the input power in response to a sensed operational parameter of the input power. The control circuit may adjust the number of the switches (14a-14e) deactivated in response to a change in the sensed operational parameter of the input power. A number of the light emitters (15) may be coupled to the input power regardless of the sensed operational parameter of the input power.
