Abstract
Disclosed is a vehicle lamp structure including a lamp cup structure and a light-emitting structure. The lamp cup structure has a first light-reflecting surface and a second light-reflecting surface. The first light-reflecting surface has a first focal point and a second focal point. The second light-reflecting surface has a third focal point and a fourth focal point. The light-emitting structure includes a first light-emitting element and a second light-emitting element. The first light-emitting element corresponds to the first focal point. The second light-emitting element corresponds to the third focal point. The first light-emitting element generates a first light source projected onto the first light-reflecting surface to form a first reflection light source through the second focal point. The second light-emitting element generates a second light source projected onto the second light-reflecting surface to form a second reflection light source through the fourth focal point.
