Claim of US Patent No. 9,967,960

1. A lighting device comprising:an AC/DC or DC/DC power converter;
a controller/processor electrically connected to the AC/DC or DC/DC power converter, wherein the controller/processor (1) determines a first number of counts for a first type or color LED to be ON to produce a blended light having a specified color and a specified intensity, and a second number of counts for a second type or color LED to be ON to produce the blended light having the specified color and the specified intensity, wherein each count corresponds to a time period, and (2) generates one or more control signals based on the first number of counts and the second number of counts;
a light emitting diode (LED) current control circuit communicably coupled to the controller/processor and electrically connected to the AC/DC or DC/DC power converter, wherein the LED current control circuit generates a first on/off signal having an on/off cycle time and a first ON time corresponding to the first number of counts for the first type or color LED, and a second on/off signal having the on/off cycle time and a second ON time corresponding to the second number of counts for the second type or color LED in response to the one or more control signals, wherein the first ON time and the second ON time start at different times within the on/off cycle;
wherein the first number of counts is determined by (a first count value based on the first type or color LED and the specified color) multiplied by (the specified intensity divided by a maximum intensity), and the second number of counts is determined by (a second count value based on the second type or color LED and the specified color) multiplied by (the specified intensity divided by the maximum intensity); and
two or more LEDs communicably coupled to the LED current control circuit and comprising at least the first type or color LED and the second type or color LED, wherein the two or more LEDs produce the blended light having the specified color in response to the first on/off signal to the first type or color LED and the second on/off signal to the second type or color LED.
