Wireless color tuning for constant-current driver

A wireless light-emitting diode (LED)-control apparatus to tune an LED array, the apparatus comprising:

• a wireless module to receive a wireless signal from a wireless control-device, the received wireless signal comprising at least one signal of signals including a correlated color temperature (CCT) value and a distance value (Duv) of a temperature of the LED array a black-body line (BBL);
• a control unit coupled to the wireless module to translate one or more signals received therefrom, the control unit further coupled to the LED array and to an LED driver, the control unit to receive power for the LED array from the LED driver and provide the power to the LED array in a manner based on the translated signals;
• and
• a dimmer emulator coupled to the control unit to provide one or more control signals to the LED driver, the dimmer emulator including:
• a current source;
• an adjustable-voltage reference coupled to the current source;
• a transistor coupled to the adjustable-voltage reference;
• and
• a resistive voltage-divider configured to have a variable voltage-divider ratio.

A wireless light-emitting diode (LED) control apparatus, the apparatus comprising:

• an LED array having at least one desaturated red LED, at least one desaturated green LED, and at least one desaturated blue LED;
• a wireless module to receive a wireless signal from a wireless control-device, the received wireless signal comprising at least one signal of signals including a desired correlated color temperature (CCT) value and a desired distance value (Duv) of a temperature of the LED array a black-body line (BBL), the Duv value being one of a positive metric or a negative metric of a color point from the BBL, the Duv indicating a greenish color, if above the BBL, or a pinkish color, if below the BBL, respectively each of the CCT and the Duv values being selected by a user of the wireless control-device;
• a control unit coupled to the wireless module to translate one or more signals received therefrom, the control unit further coupled to the LED array and to an LED driver, the control unit to receive power for the LED array from the LED driver and provide the power to the LED array;
• and
• a dimmer emulator coupled to the control unit to provide one or more control signals to the LED driver.
