Abstract (en)

[origin: WO2014094017A1] The invention relates to a light‑emitting unit (1) for a projector lamp, in particular a motor vehicle headlamp, comprising a plurality of light sources (2), a light guidance unit (3) comprising a plurality of light guides (30) and a downstream projection lens (4), wherein each light guide (30) has in each case one light exit surface (30a), and wherein each light source (2) couples light precisely into a light guide (30) assigned thereto, and wherein adjacent light guides (30) are separated from one another by separating walls (31, 32). The invention provides for at least one shield element (5) to be arranged between the light guide unit (3) and the projection lens (4), which shield element (5) has apertures (50) which are separated from one another by aperture separating walls (51, 52), wherein the shield element (5) is arranged in such a way that in each case one aperture (50) is connected upstream of a light exit surface (30a), and wherein the apertures (50) correspond substantially in terms of shape and size to the light exit surfaces (30a) in each case assigned thereto, and wherein, on those surfaces (5a) of the at least one shield element (5) which are remote from the light guide unit (3), at least some of the aperture separating walls (51, 52) have a smaller wall thickness (b) than those separating walls (31, 32) of the light guide unit (3) which are assigned to the respective aperture separating walls (51, 52).
