Abstract:
1. A method for controlling one or more lighting devices comprising the steps of: providing the one or more lighting devices, each lighting device comprising: determining a first number of counts for the first type or color LED to be ON to produce a blended light having a specified color, and a second number of counts for the second type or color LED to be ON to produce the blended light having the specified color, wherein each count corresponds to a time period; generating one or more control signals based on the first number of counts and the second number of counts using the controller/processor and sending the one or more control signals to the LED current control circuit; generating 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 using the LED current control circuit in response to the one or more control signals, wherein the on/off cycle time corresponds to at least the first ON time plus the second ON time and the first ON time does not overlap with the second ON time; sending the first on/off signal to first type or color LED and the second on/off signal to the second type or color LED; and producing the blended light having the specified color using the first on/off signal and the second on/off signal.
