Figure 2 is a cross-sectional schematic diagram of the automotive lamp of the present invention. Figure 3 is an appearance schematic diagram of the automotive lamp of the present invention. Figures 4 and 5 are a first structural schematic diagram and a second structural schematic diagram of the dimming module of the automotive lamp of the present invention. Figures 6 to 8 are application schematic diagrams of the automotive lamp of the present invention. The automotive lamp of the present invention is preferably applicable to headlights of vehicles such as automobiles.

As shown in the figure, the vehicle lamp 1 of the present invention mainly includes a lamp body 2, a lamp panel module 3 and a dimming module 4.

The lamp body 2 may include a lamp housing, a lampshade, a fixing ring for fixing the lampshade on the lamp housing, and heat dissipation components such as a heat sink and a fan. Of course, the lamp body 2 also includes a circuit module for controlling whether the lamp emits light, a connection port for electrically connecting to a car, etc., which are well known to those skilled in the art and will not be described in detail. The lamp body 2 has a receiving space 21. The lamp body 2 has an imaginary axis 211. Among them, a part of the accommodating space 21 adjacent to the light-emitting side of the lamp body 2 is cylindrical, and another part away from the lamp body 2 is a non-circular cylinder, such as a cylinder formed by symmetrically cut circles, thereby saving space and facilitating installation on the car.

The light board module 3 is disposed in the accommodation space 21 and adjacent to the light emitting side of the lamp body 2; the light board module 3 includes a light emitting unit 31 and a light guide plate 32. The light board module 3 is provided with a plurality of light emitting units 31 on the side facing the light emitting side of the lamp body 2, and the light emitting side of the plurality of light emitting units 31 is provided with a light guide plate 32; that is, the light board module 3 includes a circuit board and a plurality of light emitting units 31 disposed on the circuit board, and the light guide plate 32 is mounted on the light emitting unit 31. The circuit board is electrically connected to a circuit module that controls whether to emit light or not. It is worth mentioning that part of the light-emitting unit 31 emits light of the first color temperature, and part of the light-emitting unit 31 emits light of the second color temperature; in different embodiments, part of the light-emitting unit 31 emits light of the third color temperature. In other words, a part of the light-emitting unit 31 of the plurality of light-emitting units 31 can emit light of the first color temperature, and another part of the light-emitting unit 31 can emit light of the second color temperature. Alternatively, part of the light-emitting unit 31 emits light of the first color temperature; part of the light-emitting unit 31 emits light of the second color temperature; part of the light-emitting unit 31 emits light of the third color temperature; and part of the light-emitting unit 31 emits light of the fourth color temperature. In other words, the light panel module 3 can emit light of different color temperatures at the same time, so as to facilitate light mixing in the subsequent light path, so it should not be limited to the illustrative aspects in the embodiments.

It is worth mentioning that the light guide plate can be made of a transparent acrylic material that is resistant to high temperatures. The side of the light guide plate 32 facing away from the plurality of light-emitting units 31 includes a plurality of light-guiding portions, each of which is an aspherical body protruding from the light guide plate 32. The side of the light guide plate 32 facing the plurality of light-emitting units 31 has a distance with the plurality of light-emitting units 31, for example, 0.5 to 0.9 mm, preferably 0.7 mm, which can be adjusted according to the configuration of the light guide portion in actual use, so it should not be limited to the exemplary embodiment in this embodiment.

Thus, the light panel module 3 emits light of different color temperatures at the same time, and in the process, the light can be fully mixed inside the lamp body 2; finally, it penetrates the lampshade to the outside. Therefore, the automotive lamp 1 of the present invention has uniform color mixing and good color rendering, which can reduce the color cast phenomenon and improve the problem of ineffective provision of good lighting due to factors such as the color temperature of the white light of the LED.

The dimming module 4 is disposed in the accommodating space 21. The dimming module 4 has a dimming unit 41 and an adjustment module 42. The dimming unit 41 has a fan-shaped plane portion 411 and a curved portion 412. The fan-shaped plane portion 411 and the curved portion 412 can both shield the light emitted by the light board module 3. Furthermore, the facing direction of the fan-shaped plane portion 411 is perpendicular to the imaginary axis 211; for example, as shown in the figure, the imaginary axis 211 is the left-right direction of the figure, and the facing direction of the fan-shaped plane portion 411 is the up-down direction of the figure.

The curved surface portion 412 is connected to a portion of the edge of the sector-shaped plane portion 411 and is perpendicular to the sector-shaped plane portion 411. It is worth mentioning that the concave surface of the curved surface portion 412 faces the light-emitting side of the lamp body 2.

The adjustment module 42 is connected to the dimming unit 41; the adjustment module 42 is configured to adjust the angle between the fan-shaped plane portion 411 and the curved surface portion 412 and the imaginary axis 211, and further adjust the position of the curved surface portion 412. In other words, the adjustment module 42 can make the fan-shaped plane portion 411 and/or the curved surface portion 412 shield or not shield part of the mixed light that passes through the lampshade to the outside, so as to switch between high beam and low beam to adapt to different driving environments.

Specifically, the adjustment module 42 includes a support frame 421, an adjustment drive unit 422, a linkage 423 and a reset member 424. The dimming unit 41 can be rotatably disposed on the support frame 421 by means of a shaft. The linkage 423 can be rotatably disposed on the support frame 421 or other suitable positions of the lamp body 2 by means of a shaft. The linkage 423 is configured to selectively push against the dimming unit 41. The adjustment drive unit 422 is connected to the linkage 423 to drive the linkage 423 to operate.

It is worth mentioning that the rotation center axis of the dimming unit 41 is different from or perpendicular to the rotation center axis of the link 423. For example, the rotation center axis of the dimming unit 41 is along the two sides of the lamp body 2, while the rotation center axis of the link 423 is along the facing direction of the fan-shaped plane portion 411. Among them, the adjustment drive unit 422 can be a telescopic cylinder, so that the link 423 can be driven to rotate by the telescopic axis of the adjustment drive unit 422, and then push the dimming unit 41. Thereby, the adjustment module 42 can adjust the angle between the fan-shaped plane portion 411 and the curved surface portion 412 and the imaginary axis 211, thereby changing the light passing through the lampshade after sufficient color mixing.

The reset member 424 can be a spring or other element, which is disposed between the dimming unit 41 and the support frame 421. Thus, when the external force of the adjustment drive unit 422 driving the linking member 423 to push is reduced or removed, the dimming unit 41 can follow the external force of the linking member 423 through the reset member 424 to gradually reset to the initial state or the state without external force.

Among them, in different embodiments, the dimming module 4 may or may not include two reflective units 5. In the present embodiment, the dimming module 4 includes two reflective units 5 as an exemplary state, but it is not limited to this. Furthermore, the lamp body 2 is perpendicular to the facing direction of the fan-shaped plane portion 411 and is respectively provided with a slide groove 212. The two reflective units 5 are rectangular plate-shaped structures, and a slider portion 51 is provided on one side of each reflective unit 5. The slider portion 51 is embedded in the slide groove 212, and the long side direction of the reflective unit 5 corresponds to the imaginary axis 211. The reflective unit 5 can more fully mix the light of different color temperatures.

Preferably, the side of the reflective unit 5 opposite to the slider portion 51 can be a plane or have a microstructure, wherein the plane is, for example, a mirror surface; the microstructure includes, for example, one or more Fresnel lens structures or a concave curved surface with a part having the same curvature and a part having different curvatures.

As shown in Figures 6 to 8. Figure 6 shows the relevant data of the color temperature of 4000K of the automotive lamp of the present invention at low beam; Figure 6 mainly shows the relevant data of the exemplary color temperature of the light source before color mixing at low beam, which can be other color temperature values in actual use and is not limited to 4000K. Figure 7 shows the relevant data of the color temperature of 5700K of the automotive lamp of the present invention at low beam; Figure 7 mainly shows the relevant data of the exemplary color temperature of the light source after color mixing at low beam, which can be other color temperature values in actual use and is not limited to 5700K. Figure 8 shows the data of the automotive lamp of this invention at a color temperature of 5700K in high beam. Figure 8 mainly shows the data of the exemplary color temperature of the light source after color mixing in high beam. In actual application, it can be other color temperature values, not limited to 5700K. The automotive lamp of this invention has the advantages of uniform brightness, strong penetration, and small light loss. The light source is clear and visible, making driving safer at night. The color temperature and brightness of the light source can be adjusted manually or automatically according to weather conditions, and the switching between high beam and low beam can be adjusted, so that it can effectively respond to lighting needs in different climates and effectively improve driving safety. The above is for example only and is not restrictive. Any equivalent modifications or changes made to the original work without departing from the spirit and scope of the original work should be included in the scope of the patent application attached hereto.
