| 摘要 |
The invention relates to a lighting device (10) for a motor vehicle, comprising an electrical member (36, 38, 40; 30, 32, 34) which has for example a light source and is rigidly connected to a heat sink (42), and at least one optical module (16, 18, 20) associated with the electrical member (36, 38, 40; 30, 32, 34), the optical module (16, 18, 20) being supported by a support (22). The lighting device (10) comprises first means (50, 52, 54, 56) for positioning the optical module (16, 18, 20) on the support (22), said positioning being achieved with clearances, referred to as pre-positioning clearances, in first X, second Y and third Z directions, which are substantially perpendicular to each other, between the optical module (16, 18, 20) and the support (22), second means (58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80) for positioning the electrical member (36, 38, 40; 30, 32, 34) on the optical module in the X and Y directions, and third means (82, 84, 86, 88, 90, 92) for positioning the heat sink on the support (22) in the Z direction. |
