Referring to fig. 1 and 2, in one aspect of the present utility model, a lamp module 100 is provided _， A first lens 120 and a second lens 130, which are sequentially disposed along the optical path transmission direction, including a light source 110; the first lens 120 includes a first light incident surface 121 and a first light emergent surface 122, the second lens 130 includes a second light incident surface 131 and a second light emergent surface 132, at least one of the first light incident surface 121, the first light emergent surface 122, the second light incident surface 131 and the second light emergent surface 132 is provided with a concave curved surface 140, and the light emitted by the light source 110 passes through the first lens 120 and is emitted by the second lens 130 to form a light emergent pattern.

Specifically, the lamp module 100 provided by the utility model is provided with a light source 110, wherein the light source 110 is used for emitting light rays to form a light path of the lamp module 100 after passing through each optical element in the lamp module 100; the light emitted by the light source 110 sequentially passes through the first lens 120 and the second lens 130, that is, sequentially passes through the first light incident surface 121, the first light emergent surface 122 of the first lens 120 and the second light incident surface 131 of the second lens 130, and finally is emitted from the second light emergent surface 132 of the second lens 130, so as to form a complete light path. At least one of the first light incident surface 121, the first light emergent surface 122, the second light incident surface 131 and the second light emergent surface 132 is provided with a concave curved surface 140, so that light can be scattered in a single direction when passing through the concave curved surface 140, and the scattering direction is matched with the shape of the second lens 130, so that the second lens 130 is more comprehensively utilized, and the light is emitted from the second lens 130.

The scanning direction is preferably perpendicular to the length direction of the second lens 130, so that light can be diffused along the length direction of the second lens 130, thereby ensuring that the second lens 130 is utilized more in the length direction under the condition that the width of the second lens 130 is kept unchanged, and improving the brightness of the light. As shown in fig. 3 and 4, in the case where the width of the second lens 130 is maintained, light is diffused, and the second lens 130 is fully utilized, thereby improving the light-emitting brightness.
