Dimmable solid-state light emitting devices |
| 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. |
