Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0029] Embodiment 1
[0030] As shown in Figure 1 , a light supplementing headlamp structure comprises: an inner lampshade 4 and a thick-walled part 2, one end of the inner lampshade 4 is provided with a PCB board 1, and the PCB board 1 is provided with an LED lamp 11; the other end of the inner lampshade 4 is provided with an outer lampshade 5, and the light emitted by the LED lamp passes through the thick-walled part 2, the inner lampshade 4 and the outer lampshade 5 to form an image to achieve the vehicle lamp lighting effect.
[0031] The thick-walled part 2 is arranged inside the inner lampshade 4, and the thick-walled part 2 is coaxially arranged with the inner lampshade 4. The first light collector 211 is arranged inside the thick-walled part 2. Light of the LED lamp 11 is incident into the first light collector 211, collimated by the first light collector 211, and then is incident on the inner lampshade 4. The light is refracted by the inner lampshade 4 and the outer lampshade 5 in turn, and then is emitted to the light supplementing area for light supplementing.
[0032] In the embodiment, the thick-walled part 2 comprises a light supplementing part 21 and a light collecting part 22. The side wall of the light supplementing part 21 is connected with the side wall of the light collecting part 22. The first light collector 211 is arranged in the light collecting part 22. One end of the first light collector 211 close to the outer lampshade 5 is a concave surface. The virtual focal point of the first light collector 211 is located on the side of the PCB 1 away from the thick-walled part 2.
[0033] In the embodiment, the inner surface of the end of the inner lampshade 4 away from the PCB 1 is provided with a first light entrance surface 41. The first light entrance surface 41 is a concave curved surface. The virtual focal point of the first light entrance surface 41 is located on the side of the PCB 1 away from the thick-walled part 2. The outer surface of the end of the inner lampshade 4 away from the PCB 1 is provided with a first light exit surface 42. The first light exit surface 42 is a vertical plane.
[0034] In the embodiment, the end of the outer lampshade 5 close to the inner lampshade 4 is provided with a second light entrance surface 51. The second light entrance surface 51 is a vertical plane. The end of the outer lampshade 5 away from the inner lampshade 4 is provided with a second light exit surface 52. The second light exit surface 52 is a convex curved surface. The focal point of the second light exit surface 52 is located between the thick-walled part 2 and the first light exit surface 42.
[0035] It should be noted that the light of the LED lamp 11 is incident into the first light collector 211, collimated by the first light collector 211, and then is incident on the inner lampshade 4. The light is first refracted by the first light entrance surface 41 of the inner lampshade 4, and then is emitted from the first light exit surface 42 to the outer lampshade 5. The light is then refracted by the second light exit surface 52 of the outer lampshade 5, and then is emitted to the required position, thereby realizing light supplementing from area to area. The first light collector 211, the inner lampshade 4, and the outer lampshade 5 all have virtual focal points. The farther the virtual focal points are, the smaller the imaging of the light from the outer lampshade 5 to the light supplementing area is, thereby improving the light intensity, increasing the brightness of the light supplementing area, and further improving the light emitting effect of the vehicle lamp.
[0036] Embodiment 2:
[0037] On the basis of embodiment 1, the outer surface of the thick-walled part 2 is a curved surface. The upper side of the thick-walled part 2 is provided with a reflecting surface. The reflecting surface is provided with an aluminum film or a reflection-increasing film. The aluminum film or the reflection-increasing film forms a cutoff line on the outer surface of the thick-walled part 2, thereby avoiding the light of the LED lamp 11 from being directly emitted through the inner lampshade 4 and the outer lampshade 5 without collimation by the first light collector 211, and thereby avoiding the light from not reaching the light supplementing area.
[0038] Embodiment 3:
[0039] As Figures 2-4 shown, on the basis of embodiment 1, increase: the inside of the light collecting part 22 is provided with a plurality of second light collectors 221, and the plurality of second light collectors 221 are arranged side by side with the first light collector 211; the top end of the light collecting part 22 is connected with a thin-walled piece 3, the thin-walled piece 3 is arranged in the inside of the inner lampshade 4, and the inside of the thin-walled piece 3 is provided with a plurality of third light collectors 31.
[0040] As Figure 4 shown, the light emitted by the prior art scheme LED lamp 11 enters the thick-walled piece 2 and the thin-walled piece 3 respectively, part of the light is collimated by the second light collector 221 of the thick-walled piece 2 and then is emitted out through the inner lampshade 4 and the outer lampshade 5 in turn, part of the light is collimated by the third light collector 31 of the thin-walled piece 3 and then is emitted out through the inner lampshade 4 and the outer lampshade 5 in turn after being reflected on the thick-walled piece 2, and the light cannot be supplemented; the scheme supplements the light by increasing the first light collector 211 to refract the light entering the first light collector 211 multiple times to reach the light supplementing area, thereby improving the light emitting effect of the vehicle lamp.
[0041] In summary, part of the light emitted by the LED lamp 11 enters the first light collector 211, is collimated by the first light collector 211 and then is emitted to the inner lampshade 4, is refracted by the first light-incident surface 41 of the inner lampshade 4 and then is emitted to the outer lampshade 5, and is refracted by the second light-incident surface 52 of the outer lampshade 5 and then is emitted to the light supplementing area, thereby improving the light emitting effect of the vehicle lamp.
