Abstract:
The present invention relates to an LED-filament lamp comprising an LED-filament configured to emit LED-filament light; and an envelope comprising a light absorbing material configured to absorb light in a wavelength range of 400-440 nm to provide an amber colored appearance, wherein the envelope at least partly encloses the LED-filament, and wherein the light absorbing material is transmissive for substantially all the visible LED-filament light having wavelengths longer than 440 nm.
