A lighting device (2) for a motor vehicle (K) has a ventilating device for ventilating the interior of the lighting device. The ventilating device has at least one separate component (22, 23) which isconnected to a lower housing wall (10e) of the lighting device in the region of a ventilation opening (21) in the housing wall, and through which component (22, 23) external air can pass into the interior. The component (22, 23) is embodied as an air-guiding element by which a slip stream can be selectively deflected from the outside onto at least one specific partial region (B1, B2, B3) of a lens of the lighting device (2). The ventilation and therefore the demisting of the lighting device (2) is significantly improved. 本发明涉及种用于机动车(K)的照明设备(2)，其具有对照明设备的内部空间实施通风的器件，其中，所述器件包括至少个独立的构件(22、23)，所述构件(22、23)在壳体壁板(10e)的通风口(21)的区域内与照明设备(2)的壳体壁板(10e)相连，外部空气通过所述构件(22、23)能够到达内部空间中。本发明建议，所述构件(22、23)设计为空气导引元件，迎面风(FW)通过所述构件(22、23)能够从外部适宜地转向到照明设备(2)的反光玻璃(11)的至少个确定的局部区域(B1、B2、B3)内。以这种方式可以明显改善通风并且由此明显改善照明设备(2)的去露水。
