摘要: Light source circuitry comprises a first group of one or more light emitting diodes operable to emit color, second and third wherein the first, groups are arranged such that, when fixed current arrives at circuitry, is shared between groups, configured that proportion flows through each controllable in dependence on received control signal remainder group. The allows chromaticity combined emissions be varied gradually across range using single also without requiring use pulse width modulation (PWM)
