Lighting device (1) for coupling light into a fiber optic element (3), comprising at least one light source (2) and a light guide body (4). The light guide body is designed in the form of an intersecting/penetrating body (5) with multiple light inlet surfaces (6, 6′) and with a light outlet surface (7) for the spectral and energetic homogenization of the outlet-side luminous flux (luminous intensity distribution) of the light guide body (4). Each of the light inlet surfaces (6, 6′) is paired with a light source (2, 2′). The light outlet surface (7) is optically coupled to the fiber optic element (3). The intensity distribution across the light outlet surface (7) of at least one of the radiations coupled into the inlet surfaces (6, 6′) does not have inhomogeneities.
Lighting device (1) with a light guide body (4) for coupling the light of at least one light source (2) into a fiber optic element (3) of said lighting device (1), characterized in that, for the spectral and energetic homogenization of the exit-side luminous flux (luminous density distribution) of the light guide body (4), this is designed as an intersecting body (5) having a plurality of light entry surfaces (6, 6′) and a light exit surface (7), wherein each of the light entry surfaces (6, 6′) is allocated to a light source (2, 2′) and the light exit surface (7) is optically coupled with the fiber optic element (3).
