Abstract

An illumination system, a method for illuminating an illumination object(100, 100') and an electronic device comprising the illumination system. The illumination system comprises an illumination object (100, 100'), a light-emitting unit (106) and a discrete light channel (108) which is operationally connected to the light-emitting unit (106) and the illumination object (100,100') and which is arranged to transfer emitted light from the light source (106) to the illumination object(100, 100').
