Abstract

See full text

The present disclosure relates to a light-emitting diode (LED) filament (100) comprising a carrier (120) having a first side on which a plurality of LEDs is arranged. The plurality of LEDs comprises a LED of a first type (111) arranged to emit light having a first peak wavelength in the range 400-500 nm, a LED of a second type (112) arranged to emit light having a second peak wavelength in the range 500-570 nm, and a LED of a third type (113) arranged to emit light having a third peak wavelength in the range 590-680 nm. An encapsulant (130) encapsulates at least the LED of the first type, and at least partly the LEDs of the second type and the third type. The encapsulant (130) comprises a wavelength converting material having a higher absorption coefficient for the first peak wavelength than for the second peak wavelength and the third peak wavelength. The wavelength converting material has an emission band extending at least from 500 to 650 nm.
