Abstract (en)
[origin: WO2014048906A1] The invention relates to a light-emitting semiconductor component, having: - a light-emitting semiconductor chip (1) with an active region (11) which, in operation, emits light (31) having a first spectrum; - a wavelength conversion element (2) which is positioned remote from the semiconductor chip (1), is downstream of the semiconductor chip (1) in the beam path of the light (31) having the first spectrum and converts the light (31) having the first spectrum at least partially into light (32) having a second spectrum; and - a filter layer (3), which reflects at least a part (34) of a light (33) incident on the semiconductor component from the outside. The part (34) of the light (33) incident on the semiconductor component from the outside that is reflected by the filter layer (3) has a visible wavelength range and overlaps a colour impression produced by the wavelength conversion element when the semiconductor component is in a switched-off state.
