Abstract

The invention relates to a vehicle lighting device (3) for illuminating an interior space (2) of a vehicle (1), said vehicle lighting device (3) having at least a first light source (5) and a planar shielding element (13) , one side of the screening element (13) is oriented towards the side facing away from the interior space (2) of the vehicle (1) and the other side of the screening element (13) is oriented towards the side facing the interior space (2) of the vehicle (1). Furthermore, the vehicle lighting device (3) includes a light guide (4) with a light input surface (10) on the side of the shielding element (13) facing away from the interior (2) of the vehicle (1), A first light source (5) is arranged at the light input surface (10) and the light radiation of the first light source (5) is input into the light input surface (10), and the light guide (4) has a shielding element (13) The light output surface (16) on the side facing the interior space (2) of the vehicle (1), the input light is output to the interior space (2) of the vehicle (1) at the light output surface (16), wherein the guide The light body (4) extends around the shielding element (13) from the side facing away from the interior space (2) of the vehicle (1) to the side facing the interior space (2) of the vehicle (1). The vehicle lighting device (3) is characterized in that the screening element (13) has at least one opening (14) and in that at least one opening (14) is arranged on a side of the screening element (13) facing away from the vehicle interior (2). A second light source (18) whose light radiation passes through the opening (14) and the light guide (4) reaches the vehicle interior (2).

Description

technical field [0001] The invention relates to a vehicle lighting device for lighting a vehicle interior, which has at least one first light source and a planar shading element, one side of which is oriented towards a side facing away from the vehicle interior and The other side of the shielding element is oriented towards the side facing the vehicle interior.
