Abstract
An automotive headlamp system and an automotive lamp. The automotive headlamp system comprises a light source, a primary optical element, an automotive signal lamp structure, and a secondary optical element arranged sequentially along the light emitting direction. The automotive signal lamp structure comprises a light-transmitting portion and a rotating shaft. The light-transmitting portion comprises at least one light-transmitting plate mounted on the rotating shaft which can be driven to rotate by the rotating shaft. By means of rotation, light from the light source exits from the primary optical element, then selectively passes through one of or none of the light-transmitting plates, and is then projected by means of the secondary optical element to achieve a corresponding signal lamp function. The light-transmitting plate mounted on the rotating shaft is used to replace an existing signal lamp, reducing the space occupied by the original signal lamp, decreasing the volume of a headlamp.
