Abstract
Disclosed is a vehicle lamp module, including a lamp cup structure, a light-emitting structure, and a lens structure. The lamp cup structure has multiple light-focusing curved surfaces, where each of the light-focusing curved surfaces has a first focal point and a second focal point, and the first focal point and the second focal point of each light-focusing curved surface are located on an axis of the light-focusing curved surface. The light-emitting structure includes multiple light-emitting elements, where each of the light-emitting elements is disposed corresponding to the first focal point of a corresponding one of the light-focusing curved surfaces. The lens structure has a lens focal point, a primary optical axis, and a reference line, where the lens focal point is located at an intersection point of the primary optical axis and the reference line and the reference line is parallel to the lens structure.
