Abstract: A lighting circuit uses a tapped linear driver architecture in which there are at least two LED types; a first LED type with a first forward voltage, and a second LED type with a second forward voltage at least double the first forward voltage. The first segment of the tapped linear driver comprises more LEDs of the first type than the second type and the last segment comprises more LEDs of the second type than the first type. This arrangement enables a reduction in the number of LEDs needed, but without significantly impacting on the efficiency of the circuit.
