The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1 to 5, the lamp module of the present invention, including a circuit board 3, a heat sink 4 and at least one reflector 1, since part of direct light emitted from a light source may cause glare for pedestrians or oncoming drivers, in order to avoid occurrence of traffic accidents without causing glare, a light shield 2 is provided, and the light shield 2 is disposed near the light source, and can block part of direct light propagating toward a lens, and also block scattered or diffused light from the light source from being projected toward a specific area of the reflector, so as to define a desired light pattern and prevent unwanted light and glare outside the desired light pattern. Since the light shield 2 is relatively close to the light source, in order to improve the service life thereof, the light shield 2 is made of a high-strength metal, preferably ADC12 (japanese brand, also called aluminum material No. 12, Al-Si-Cu alloy, which is a die-cast aluminum alloy).

In order to improve the heat conductivity of the heat sink 4, the heat sink 4 of the present invention is made of aluminum, which has higher heat conductivity than the prior art heat sink made of aluminum alloy, but has lower strength and is easy to deform, so that the heat sink 4 cannot be processed with a positioning pin or a riveting column, and the light shield is made of a high-strength metal material, and a positioning pin and a riveting column can be arranged thereon.

The anti-overturning convex rib 13 extends to the edge of the lower surface of the reflector 1, the supporting area of the anti-overturning convex rib 13 is enlarged, and the overturning trend of the reflector 1 in the fastening process is eliminated as much as possible.

However, after the front end of the reflector 1 is riveted with the circuit board 3, the rear end of the reflector 1 tends to tilt upwards due to the stress on the front end of the reflector 1, that is, the reflector 1 can be tilted forwards, in order to inhibit the reflector 1 from being tilted forwards, as shown in fig. 16, an anti-tilting auxiliary structure for preventing the reflector 1 from being tilted is arranged around the reflector riveting column 14, the anti-tilting auxiliary structure is an auxiliary supporting convex rib 15, the auxiliary supporting convex rib 15 is in contact with the upper surface of the circuit board 3, and when the reflector 1 is tilted forwards, the auxiliary supporting convex rib 15 can inhibit the reflector 1 from being tilted forwards.

The lower surfaces of the anti-overturning convex rib 13 and the auxiliary supporting convex rib 15 are also positioning surfaces in the vertical direction of the reflector 1.

As shown in fig. 3 to 21, a first positioning structure is disposed between at least one of the reflectors 1 and the circuit board 3, so as to directly position the reflector 1 and the circuit board 3 through the first positioning structure. First location structure is including establishing a plurality of speculum location bolt 11 on the speculum 1 and establishing on the circuit board 3 with speculum location socket 33 that speculum location bolt 11 corresponds, speculum location bolt 11 can pass speculum location socket 33 in order to fix a position speculum 1 and circuit board 3 accurate positioning. In a preferred embodiment of the present invention, there are two reflector positioning pins 11 and two reflector positioning sockets 33. Similarly, to avoid over-positioning, one of the two reflector positioning sockets 33 is a waist-shaped opening, and the outer surface of the reflector positioning bolt 11 corresponding to the waist-shaped opening is attached to two inner side planes of the waist-shaped opening; the other reflector positioning socket 33 is a circular hole, and the outer surface of the reflector positioning bolt 11 corresponding to the circular hole is attached to the inner surface of the circular hole.

The reflector 1 and the circuit board 3 are directly positioned, and also do not need to be positioned with the heat sink 4, but for convenience of processing and assembly, a second through hole 43 for the reflector positioning pin 11 to pass through is formed in the heat sink 4 corresponding to the circuit board 3, and the reflector positioning pin 11 is not in contact with the inner wall of the second through hole 43.

A second positioning structure is arranged between the light shield 2 and the circuit board 3, so that the light shield 2 and the circuit board 3 can be directly positioned through the second positioning structure. Specifically, the second positioning structure includes a plurality of hood positioning pins 21 provided on the hood 2 and hood positioning sockets 31 provided on the circuit board 3 and corresponding to the hood positioning pins 21, and the hood positioning pins 21 can pass through the hood positioning sockets 31 to accurately position the hood 2 and the circuit board 3. As shown in fig. 3-5, which are a preferred embodiment of the present invention, the two light shield positioning pins 21 and the two light shield positioning insertion holes 31 are both provided, conventionally, in order to avoid over-positioning, one of the light shield positioning insertion holes 31 is a waist-shaped hole, and the outer surface of the light shield positioning pin 21 corresponding to the waist-shaped hole is attached to two inner side planes of the waist-shaped hole (as shown in fig. 13); the other lens hood positioning insertion opening 31 is a circular hole, and the outer surface of the lens hood positioning insertion pin 21 corresponding to the circular hole is attached to the inner surface of the circular hole (as shown in fig. 12).

The light shield 2 and the circuit board 3 are directly positioned without being positioned with the heat sink 4, but for convenience of processing and assembly, a first through hole 41 for the light shield positioning pin 21 to pass through is formed in the heat sink 4 corresponding to the circuit board 3. The light shield positioning pin 21 does not contact the inner wall of the first through hole 41.

As an embodiment of the present invention, the light shield 2, the circuit board 3, and the heat sink 4 are connected by the following structure: the improved circuit board structure is characterized in that at least one lens hood riveting column 22 is arranged on the lens hood 2, a circuit board connecting hole 32 corresponding to the lens hood riveting column 22 is arranged on the circuit board 3, a radiator connecting hole 42 corresponding to the lens hood riveting column 22 is arranged on the radiator 4 corresponding to the circuit board 3, and the lens hood riveting column 22 penetrates through the circuit board connecting hole 32 and the radiator connecting hole 42 in sequence to rivet the lens hood 2, the circuit board 3 and the radiator 4. As shown in fig. 11, the number of the shield riveting posts 22, the circuit board connecting holes 32 and the radiator connecting holes 42 is two, the shield riveting posts 22 can sequentially penetrate through the circuit board connecting holes 32 and the radiator connecting holes 42 to rivet the shield 2, the circuit board 3 and the radiator 4, and the shield riveting posts 22 and the shield 2 are made of the same material and are all metal pieces, so that the riveting with the circuit board 3 and the radiator 4 is cold riveting. In order to improve the thermal durability of the lamp module, as shown in fig. 11, a gap for the movement of the lens hood anchor 22 in the attachment hole exists between the outer surface of the lens hood anchor 22 and the inner surfaces of the circuit board attachment hole 32 and the heat sink attachment hole 42.

Preferably, the hood positioning pin 21 and the hood riveting post 22 are made of metal, so that the heat conduction performance is good, and a heat conduction adhesive can be arranged between the hood positioning pin and the circuit board 3, so that heat conduction is realized, and the heat dissipation efficiency is improved.

The reflector 1 can be provided with a plurality of light shapes and used for forming a plurality of light shapes, the plurality of light shapes can be overlapped to form a complete vehicle light shape, in the light distribution process, a light adjusting structure is needed to adjust the relative positions of the plurality of light shapes, and then the position of the whole vehicle light shape is adjusted. Wherein the relative position between the plurality of light shapes can be adjusted by adjusting the position of the reflector 1 relative to the light source on the circuit board 3.

Taking the three reflectors 1 as an example, the three reflectors 1 are respectively a main low beam reflector 101, an auxiliary low beam reflector 102 and a high beam reflector 103, which are respectively used for forming a main low beam shape (shown in fig. 22), an auxiliary low beam shape (shown in fig. 23) and a high beam shape (shown in fig. 25), respectivelyThe main low beam light pattern and the auxiliary low beam light pattern are superimposed to form a complete low beam light pattern (shown in fig. 24). The main low beam reflector 101, the auxiliary low beam reflector 102 and the high beam reflector 103 are integrated, and are integrally formed by using PC (polycarbonate), PMMA (polymethyl methacrylate) or BMC (bulk molding compound), and then are aluminized on the surface serving as the reflecting surface to form the reflecting surface. The positions of the three reflectors 1 can be set arbitrarily, and in fig. 1, the auxiliary low beam reflector 102 and the high beam reflector 103 are respectively arranged at the left and right sides of the main low beam reflector 101. In order to increase the illumination of the main and low beam areas, the light source corresponding to the main low beam reflector 101 has a smaller light emitting area than the light sources corresponding to the other two reflectors, and the light emitting area is less than or equal to 0.5mm²。

As shown in fig. 18-19, the main low beam reflector 101 is fixedly connected to the circuit board 3 and the heat sink 4 by using the main low beam shape as a positioning reference, the reflector positioning pins 11 are disposed on the main low beam reflector 101, the reflector positioning sockets 33 are disposed on the circuit board 3 corresponding to the main low beam reflector 101, the dimming structure includes at least one guiding post 16 disposed on the left and right sides of the auxiliary low beam reflector 102 and the far beam reflector 103, respectively, and a circuit board guiding hole 36 disposed on the corresponding circuit board 3 and corresponding to the guiding post 6, and the circuit board guiding hole 36 extends along the front-back direction of the circuit board 3. The guiding post 16 can move along the front-back direction of the guiding hole 36 of the circuit board to realize the relative position of the small assembly formed by the light shield 2, the circuit board 3 and the heat sink 4 corresponding to the auxiliary low beam reflector 102 and the high beam reflector 103 relative to the auxiliary low beam reflector 102 and the high beam reflector 103 in the front-back direction, that is, the position of the light source and the reflector 1 in the front-back direction can be realized, and finally the relative position of the auxiliary low beam shape and the high beam shape in the up-down direction relative to the main low beam shape can be adjusted.

Meanwhile, the guide posts 16 and the circuit board guide holes 36 also serve as a limit structure for the small assembly consisting of the light shield 2, the circuit board 3 and the heat sink 4 corresponding to the auxiliary low-beam reflector 102 and the auxiliary high-beam reflector 103 in the left-right direction, so that the small assembly can only move in the front-back direction. Specifically, the outer edges of the guide posts 16 contact the inner walls of the board guide holes 36, and the inner edges of the guide posts 16 do not contact the inner walls of the board guide holes 36 (here, "inner" of the "inner edges" refers to a direction toward the center of the auxiliary low beam reflector 102 or the high beam reflector 103, and "outer" of the "outer edges" refers to a direction away from the center thereof). As an embodiment of the present invention, as shown in fig. 20 to 21, the right edge of the guide post 16 located on the right side is attached to the right edge of the corresponding circuit board guide hole 36, and a gap is formed between the left edge of the guide post 16 and the left edge of the corresponding circuit board guide hole 36; the left edge of the guide post 16 on the left side is abutted against the left edge of the circuit board guide hole 36 corresponding thereto, and a gap is provided between the right edge of the guide post 16 and the right edge of the circuit board guide hole 36 corresponding thereto.

If the left side and the right side of the auxiliary low beam reflector 102 and the high beam reflector 103 are respectively provided with one guide column 16, the guide columns 16 are cylinders, and the circuit board guide holes 36 are strip-shaped holes, when the small assembly is pushed by a special pushing mechanism, the small assembly is easy to rotate in the front and back moving process due to the fact that the two guide columns 16 and the two circuit board guide holes 36 are in point contact, and inaccurate dimming is caused; if the guide posts 16 are strip-shaped posts, the circuit board guide holes 36 are strip-shaped holes, and the guide posts 16 and the circuit board guide holes 36 are in line contact, the small assembly is easy to be blocked due to rotation in the front and back moving process. Therefore, as shown in fig. 18, in a preferred embodiment, the guiding posts 16 are cylinders, one side of the auxiliary low beam reflector 102 is provided with one guiding post 16, the other side is provided with two guiding posts 16, and the outer edges of the two circuit board guiding holes 36 corresponding to the two guiding posts 16 located on the same side are located on the same straight line; one side of the high-beam reflector is provided with one guide column 16, the other side of the high-beam reflector is provided with two guide columns 16, and the outer edges of the two circuit board guide holes 36 corresponding to the two guide columns 16 on the same side are positioned on the same straight line. Because the three guide posts 16 and the three circuit board guide holes 3 are all in point contact, and the contact points of the two guide posts 16 are in the same straight line, the structure can not cause the small assembly to rotate in the process of moving back and forth, and can not cause the phenomenon of locking.

The auxiliary low beam reflector 102 and the radiator 4 corresponding to the high beam reflector 103 are both provided with radiator guide holes 45 corresponding to the circuit board guide holes 36, and the guide posts 16 sequentially penetrate through the circuit board guide holes 36 and the radiator guide holes 45.

Because the small assembly is moved relatively to the reflector 1 in the front-back direction, the circuit board 3 and the through holes 34 and 44 on the heat sink 4 corresponding to the auxiliary low beam reflector 102 and the high beam reflector 103 and the riveting hole 35 on the circuit board 3 are all strip-shaped holes extending in the front-back direction, and after the dimming is finished, the small assembly and the reflector 1 are fixedly connected through the screw 5 or the bolt and are riveted through the reflector riveting column 14.

The relative movement can be back and forth movement or up and down movement, or movement in other directions, as long as the relative position adjustment between the light shapes can be realized.

The car light module further comprises a support 6, and the reflector 1 is fixed on the support 6. After the dimming of the relative positions of the light shapes is finished, the reflective car lamp module can be dimmed integrally by adjusting the bracket 6, so that the light shape of the car lamp shown in fig. 26 is located at the theoretical position.
