Led filament comprising leds arranged to emit violet and uv light

Abstract

There is provided a light emitting diode, LED, filament, configured to emit LED filament light (105). The LED filament comprises an elongated carrier (110) extending in a first direction, A, comprising a first surface (112) and a second surface (114) oppositely arranged the first surface. The LED filament further comprises a first linear array (120) of a plurality of first light emitting diodes, LEDs, arranged on the first surface, wherein the plurality of first LEDs is arranged to emit ultra-violet, UV, light (121) with a first centroid wavelength, Xc1, in a wavelength range of 100-380 nm. The LED filament further comprises a second linear array (130) of a plurality of second LEDs, arranged on the second surface, wherein the plurality of second LEDs is arranged to emit violet light (131) with a second centroid wavelength, Xc2, in a wavelength range of 380-420 nm.
