FIELD: electricity.SUBSTANCE: invention relates to lighting engineering. The built-in lighting unit (1A, 1B, 1C, 1D, 1E) comprises optical arrangement (2, 3), the first light source (S) to generate the first light beam (L), the first collimator (C) to guide the first light beam (L) to the optical arrangement (2, 3); the second light source (S) to generate the second light beam (L), the second collimator (C) to guide the second light beam (L) to the optical arrangement (2, 3); at that the optical arrangement is realised so that it may manipulate the first and second light beams (L, L) generating the first outgoing light beam (B) and the second outgoing light beam (B) so that the first outgoing light beam (B) and the second outgoing light beam (B) are joined partially in overlay area (44) in projection plane (4) placed at a preset distance from the built-in lighting unit (1A, 1B, 1C, 1D, 1E). The invention also describes an automobile head lamp unit (12) that contains the built-in lighting unit (1A, 1B, 1C, 1D, 1E).EFFECT: increased lighting efficiency of low-beam and high-beam light and increased safety for a driver.13 cl, 10 dwg |
