Non-motor vehicles such as bicycles, electric motorcycles or electric tricycles are important travel tools for people. When a rider rides the vehicle at night, in order to ensure night driving safety, the rider usually installs a lamp at the head of the vehicle to illuminate a driving route. However, in real situations, the light conditions and traffic conditions of roads are variable, and therefore, the vehicle lamp needs to have both near light and far light functions to meet the actual use requirements. For example, if the light of the road is sufficient or more pedestrians are on the road, the vehicle lamp of the vehicle can emit short light, the energy consumption of the vehicle lamp is reduced, and the interference of the light emitted by the vehicle lamp to the sight of the pedestrians is avoided; for another example, if the light of the road is dark and the traffic condition is smooth, the lamp of the vehicle can emit high beam to ensure the riding vision of the rider.
In the related art, a light receiving lens and a light emitting lens are generally disposed in a vehicle lamp, and light generated by a light source can form a near light spot and a far light spot through a refraction surface of the light receiving lens and a refraction surface of the light emitting lens. In the production and manufacturing process, the light receiving lens and the light emitting lens can be installed in the car lamp shell in a grading manner, or the light receiving lens and the light emitting lens are firstly assembled and then installed in the car lamp shell, however, the assembling process is complex and the assembling efficiency is low.

Furthermore, the focus of the light-emitting lens 12 is arranged opposite to the high beam light source 3 capable of emitting high beam light, and the light-emitting lens 12 is also used for collimating and emitting the high beam light irradiated to the focus thereof, so that a high beam light spot with long irradiation distance, high brightness and concentrated light is formed, and a rider can obtain the view field at a long distance; when the high-beam light source device is used specifically, the high-beam light source 3 is arranged on one side of the reflecting part 13, which is far away from the light-emitting lens 12, so that the high-beam light source 3 is ensured to be just opposite to the focus of the light-emitting lens 12, and can be sequentially emitted into the reflecting part 13 and the light-emitting lens 12.

In the production design process, the angle value of the second inclination angle formed between the second light reflecting surface 132 and the axis of the light emergent lens 12 is changed, so that the height of the dipped beam light spot emitted by the vehicle lamp can be correspondingly changed, and the lighting requirements of vehicles with various heights can be met. In addition, the value of the first inclination angle formed between the first light reflecting surface 131 and the axis of the condenser lens 11 can be reasonably designed according to the second inclination angle, so that the near-beam light converged by the condenser lens 11 can be reflected to the second light reflecting surface 132 and the light emitting lens 12 as much as possible, the brightness of the near-beam light spot can be ensured, and the night driving safety can be guaranteed.

In this embodiment, since the focal point of the light-emitting lens 12 with the convex surface 121 can be directly opposite to the high beam light source 3 of the vehicle lamp, according to the principle of the convex lens, the high beam light emitted from the focal point of the light-emitting lens 12 with the convex surface 121 is emitted to the light-emitting lens 12 with the convex surface 121, and is converged by the light-emitting lens 12 with the convex surface 121, and then can be collimated and emitted in parallel with the main optical axis of the light-emitting lens 12 with the convex surface 121, so that a high beam spot as shown in fig. 7 can be formed, and the light source has the characteristics of large range, large brightness and concentrated light.

It should be noted that the large end and the small end of the tir lens are defined relatively, that is, the large end is defined as the large area and the small end is defined as the small area when the areas of the two ends are compared.
In practical situations, the tir lens and the reflective cup can both converge and reflect light, however, if the light is emitted at a certain angle, the size of the reflective cup is larger than that of the tir lens, so that the combined lens 1 in this embodiment uses the tir lens as the condensing lens 11, which can effectively reduce the sizes of the combined lens 1 and the vehicle lamp. In addition, the small end of the total internal reflection lens is used as a light inlet end to facilitate the convergence of near light rays, and the small end of the total internal reflection lens is used as a light outlet end to facilitate the improvement of the emergence rate of the near light rays.
