[0037] Embodiment 1:
[0038] As Figures 1 to 2As shown, a dual-focus condenser structure, which includes: a condenser body 1, one end of the condenser body 1 forms a light incident end 2, the other end of the condenser body 1 forms a light exit end 3, and the condenser body 1 includes a first condenser structure 4 and a second condenser structure 6 that are spliced and connected to each other. Both the first condenser structure 4 and the second condenser structure 6 are located between the light incident end 2 and the light exit end 3;
[0039] The first condenser structure 4 includes a first refracting surface 9 and a first total reflection surface 11. The second condenser structure 6 includes a second refracting surface 10 and a second total reflection surface 12. The first total reflection surface 11 is arranged outside the first refracting surface 9. The second total reflection surface 12 is arranged outside the second refracting surface 10. The upper end of the first refracting surface 9 is lower than that of the first total reflection surface 11. The upper end of the second refracting surface 10 is lower than that of the second total reflection surface 12. The first refracting surface 9 and the first total reflection surface 11 are connected by a second refracting portion 5. The second refracting surface 10 and the second total reflection surface 12 are connected by a second refracting portion 5. The opening formed by the splicing of the first refracting surface 9 and the second refracting surface 10 faces the light exit end 3.
[0040] It should be noted here that: the first condenser structure 4 and the second condenser structure 6 are spliced. The first refracting surface 9 has a first focus 7, and the second refracting surface 10 has a second focus 8. With this design of the dual-focus structure, even if the LED has two light colors, each light color is set at one focus and will not be out of focus. When multiple functions share one light exit, the light patterns of each function will not shift, the light output is efficient, the power consumption is reduced, and the lighting is uniform.
[0041] The upper end of the first refracting surface 9 is lower than that of the first total reflection surface 11, and the upper end of the second refracting surface 10 is lower than that of the second total reflection surface 12. This design maximizes the light efficiency. The opening formed by the connection of the first refracting surface 9 and the second refracting surface 10 faces the light exit end 3. This design is to ensure that the first refracting surface 9, the second refracting surface 10, and the second refracting portion 5 cooperate with the first total reflection surface 11 and the second total reflection surface 12 to collimate the light and the lighting is uniform.
[0042] The first refracting surface 9 has a first focus 7, and the second refracting surface 10 has a second focus 8.

When the cross-sections of the first total reflection surface 11, the second total reflection surface 12, the first refraction surface 9 and the second refraction surface 10 are all inferior arcs, as Figure 2 shown, an ellipsoidal shape is formed.
[0045] Diffusion patterns or leather grains are provided on the first refraction surface 9, the first total reflection surface 11, the second refraction surface 10, the second total reflection surface 12 and the second refraction part 5.

[0047] As Figure 1 shown, a vehicle lamp includes an LED and a dual-focus condenser structure as described in any one of the above. The LED has two emission points 18. The left emission point 18 is coincidentally arranged with the second focus 8, and the right emission point 18 is coincidentally arranged with the first focus 7. A part of the light emitted from the second focus 8 is refracted by the second refraction surface 10 and collimated and emitted from the light exit end 3, and another part is refracted by the second refraction part 5 and then hits the first total reflection surface 11. After total reflection by it, it is collimated and emitted from the light exit end 3; a part of the light emitted from the first focus 7 is refracted by the first refraction surface 9 and collimated and emitted from the light exit end 3, and another part is refracted by the second refraction part 5 and then hits the second total reflection surface 12.

The left light-emitting point 18 is arranged to coincide with the first focus 7, and the right light-emitting point 18 is arranged to coincide with the second focus 8. Among them, a part of the light emitted from the first focus 7 is refracted by the first refraction surface 9 and collimated and emitted from the light-emitting end 3, and another part is refracted by the second refraction part 5 and then hits the second total reflection surface 12.

The left light-emitting point 18 is arranged to coincide with the second focus 8, and the right light-emitting point 18 is arranged to coincide with the first focus 7. Part of the light emitted from the second focus 8 is refracted by the second refracting surface 10 and then collimated and emitted to hit the inclined total reflection surface 14.

The left light-emitting point 18 is arranged to coincide with the second focus 8, and the right light-emitting point 18 is arranged to coincide with the first focus 7. Part of the light emitted from the second focus 8 is refracted by the second refracting surface 10 and then collimated and emitted to hit one side surface of the dentate body 17. After total reflection by it, it hits the other side surface of the dentate body 17. After total reflection by it, it is emitted from the light-emitting surface 15.
