  • Patent number: 8203260
    Abstract: A color temperature tunable white light source comprises: first and second LED arrangements operable to emit light of first and second wavelength range respectively that are configured such that their combined light output, which comprises light generated by the source, appears white in color. One or both LED arrangements comprises a phosphor provided remote to an associated LED operable to generate excitation radiation and to irradiate the phosphor such that it emits light of a different wavelength range, wherein the light emitted by the LED arrangement comprises the combined light from the LED and phosphor. The color temperature of output white light is tunable by controlling the relative light outputs of the LED arrangements by for example controlling the relative magnitude of the drive currents of the LEDs or a duty cycle of a pulse width modulated drive current.
