Motor vehicle light-emitting optical module

Motor vehicle optical module for emitting at least two light-emitting segments that can be activated selectively, the module including:

• a substrate;
• at least two light sources mounted on the substrate each of which can be activated selectively to emit light rays;
• a primary optical component adapted to form primary light beams from the light rays emitted by each light source;
• a secondary optical component adapted to project each of the primary light beams to form said light-emitting segments;
• and
• a single support that carries the substrate, the primary optical component and the secondary optical component, wherein the single support includes a bearing surface to position the secondary optical component relative to the substrate, and the substrate is a horizontal plate that is disposed vertically between an upper face of a cooling block and the bearing surface on the support.
