Abstract:
A white light emitting device or LED-filament comprises: a solid-state light emitter (LED) operable to generate excitation light; a first phosphor associated with the solid-state light emitter to generate light with a peak emission wavelength in a range 500 nm to 575 nm; and a second phosphor associated with the solid-state light emitter to generate light with a peak emission wavelength in a range 600 nm to 650 nm, wherein a percentage decrease in conversion efficiency corresponding to an increase in excitation light photon density exhibited by the second phosphor is larger than a percentage decrease in conversion efficiency corresponding to the same increase in excitation light photon density exhibited by the first phosphor.

Claim (Index 19):
A method of dimming a white light emitting device or LED-filament comprising the steps of:\n providing a solid-state light emitter to generate excitation light with a dominant wavelength in a range 440 nm to 470 nm; providing a first phosphor associated with the solid-state light emitter to generate light with a peak emission wavelength in a range 500 nm to 575 nm; providing a second phosphor associated with the solid-state light emitter to generate light with a peak emission wavelength in a range 600 nm to 650 nm; wherein a percentage decrease in conversion efficiency corresponding to an increase in excitation light photon density exhibited by the second phosphor is larger than a percentage decrease in conversion efficiency corresponding to the same increase in excitation light photon density exhibited by the first phosphor; and decreasing the DC power to the solid-state light emitter to decrease the excitation light photon density.
