Abstract (en)
[origin: EP4206524A1] Provided are an optical reflecting system for a vehicle lamp illumination device and a vehicle lamp illumination device, which comprises a primary optical system having a light source (80), and the optical reflecting system is configured to receive light beams emitted from the light source (80) of the primary optical system. The optical reflecting system comprises a first reflector having a first reflecting surface (10) and a second reflector having a second reflecting surface (20), wherein the first reflecting surface (10) is configured to collimate light in a first direction, and the second reflecting surface (20) is configured to collimate light in a second direction orthogonal to the first direction. The first reflecting surface (10) and the second reflecting surface (20) have a curved shape represented by a contour line, and the curved shape is a curved surface formed by stretching the contour line along a direction normal to a plane where the contour line is located. The optical reflecting system is configured such that light beams emitted from the primary optical system having the light source (80), after being reflected by the first reflector and the second reflector, are emitted in a form of approximately parallel light beams, so as to form an illumination light pattern of the vehicle lamp illumination device.
