Claim 4:
5. The device of claim 1, further comprising a bluish light flux balancing resistor element having a first end and a second end, the first end of the bluish light flux balancing resistor element being electrically coupled in series to the second end of the first string of LEDs, the second end of the blueish light flux balancing resistor being electrically coupled to the second end of the red light flux balancing resistor, the second string of LEDs and red light flux balancing resistor series being arranged in parallel with the first string of LEDs and the blueish light flux balancing resistor series and configured to redistribute current in response to a fluctuation of a junction temperature of the first string of LEDs, wherein the blueish light balancing resistor element includes a passive resistor element having a predefined value based on one or more physical properties of at least one of the first and second strings of LEDs to generate the predefined desirable color point.
