The invention relates to a light guide unit (3) for a light-emitting unit (1) for a projector lamp, in particular a motor vehicle headlamp, wherein the light-emitting unit (1) comprises a plurality of light sources (2), the light guide unit (3), and a downstream projection lens (4), wherein the light guide unit (3) has a plurality of light guides (30), wherein each light guide (30) has a 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). In accordance with the invention the light guide unit (3) comprises an accommodating element (5), which accommodating element (5) has an accommodating opening (5a) which passes completely through the accommodating element (5) in the light exit direction, and furthermore comprises at least one light guide body (6), which at least one light guide body (6) is in the form of a component formed separately from the accommodating element (5), in which at least one light guide body (6) at least some of the light guides (30) of the light guide unit (3) are formed, and wherein the at least one light guide body (6) is inserted into the accommodating opening (5a) of the accommodating element (5).
