[0028] like Figure 1 The figure shows a specific embodiment of the vehicle light source module of the utility model, which can be used as a vehicle headlight. The light source module includes a heat sink 10, a PCB board 20 fixed on the heat sink 10, a focusing assembly 30 and a lens bracket 40; wherein, at least one low-beam light source 21 and at least one high-beam light source 22 are arranged on the PCB board 20; specifically, two groups of light sources are arranged on the PCB board 20, including a group of low-beam light sources 21 located on the upper side and arranged at intervals in the horizontal direction, and a group of high-beam light sources 22 located on the lower side and arranged at intervals in the horizontal direction. The focusing assembly 30 includes a low-beam focusing device 31, a high-beam focusing device 32 and a light-dark cutoff baffle 33; the focusing assembly 30 is integrally injection molded; a lens 60 is arranged on the side of the lens bracket 40 away from the PCB board 20.

[0029] The above-mentioned vehicle light source module consists of three major parts: a PCB board 20, a focusing assembly 30 and a lens bracket 40, which can be detachably installed on the radiator 10 respectively. Among them, the low beam focusing assembly 31, the high beam focusing assembly 32 and the light-and-dark cut-off line baffle 33 in the focusing assembly 30 are integrally injection molded, so that the structure of the entire light source module is simple. The focusing assembly 30 occupies less space through integral injection molding than the assembly of the three, so that the light source module is miniaturized. The opening size of the light source module on the vehicle body is small. Under the premise of ensuring good optical performance requirements, it can better meet the design requirements of the light source module with hidden shape, and give the shape surface more free design space.

[0030] Specifically, in an optional embodiment, the focusing assembly 30 includes a frame-type main body 30a, and a connecting portion 30b is integrally formed on the frame-type main body 30a, and the frame-type main body 30a is detachably connected to the heat sink 10 through the connecting portion 30b. More specifically, the connecting portion 30b is provided in three groups, one group is provided on the upper side of the frame-type main body 30a, and two groups are provided on the lower side; the connecting portion 30b is provided with a connecting hole; and the connection between the frame-type main body 30a and the heat sink 10 is achieved by a fastening component penetrated through the connecting hole.

[0031] Specifically, in an optional embodiment, the arc-shaped incident portion 31a of the low-beam concentrator 31 and the arc-shaped incident portion 32a of the high-beam concentrator 32 are formed on one side of the frame-type main body 30a facing the PCB board 20; the number and position of the arc-shaped incident portions 31a of the low-beam concentrator 31 correspond to the low-beam light source 21, and the number and position of the arc-shaped incident portions 32a of the high-beam concentrator 32 correspond to the high-beam light source 22. After the frame-type main body 30a is connected to the heat sink 10, the arc-shaped incident portion 31a of the low-beam concentrator 31 on the PCB board 20 on the frame-type main body 30a abuts against the exit surface of the low-beam light source 21, and the arc-shaped incident portion 32a of the high-beam concentrator 32 abuts against the exit surface of the high-beam light source 22.

[0032] Specifically, in one embodiment, the light emitting portion of the low beam concentrator 31 and the light emitting portion of the high beam concentrator 32 are formed on one side surface of the PCB board 20, and the light emitting portion of the low beam concentrator 31 and the light emitting portion of the high beam concentrator 32 are separated by a light-dark cut-off baffle 33. The above structure can make the gap between the high and low beams smaller, and provide the driver with a better visual experience when the road lighting is turned on, thereby improving the driving safety of the whole vehicle. More specifically, the frame-type main body 30a is formed into a rectangular frame structure with one end open and the other end closed, and the arc-shaped incident portion 31a of the low beam concentrator 31 and the arc-shaped incident portion 32a of the high beam concentrator 32 are located on a side surface of the frame-type main body 30a having an opening, and the light emitting portion of the low beam concentrator 31 and the light emitting portion of the high beam concentrator 32 are located on a side surface of the frame-type main body 30a opposite to the opening.

[0033] Specifically, in a specific embodiment, the light emitting portion of the low beam concentrator 31 is a first protrusion 31b protruding from the surface of the frame-type main body 30a, and the surface of the first protrusion 31b on one side away from the PCB board 20 forms the light-gathering light-emitting surface of the low beam concentrator 31. The light emitting portion of the high beam concentrator 32 is a second protrusion 32b protruding from the surface of the frame-type main body 30a, and the surface of the second protrusion 32b on one side away from the PCB board 20 forms the light-gathering light-emitting surface of the high beam concentrator 32. More specifically, the first protrusion 31b and the second protrusion 32b are respectively formed into rectangular protrusion structures, and their surfaces are respectively formed into inwardly concave arc surfaces to form a light-gathering effect.

[0034] Specifically, the second protrusion 32b is located at the lower side of the first protrusion 31b, and the protrusion height of the second protrusion 32b is greater than the protrusion height of the first protrusion 31b, that is, the thickness of the second protrusion 32b protruding from the surface of the frame-type main body 30a is greater than the thickness of the second protrusion 32b protruding from the surface of the frame-type main body 30a. The upper side surface of the second protrusion 32b forms a light-dark cut-off line baffle 33. More specifically, the lower side surface of the first protrusion 31b abuts or overlaps with the light-dark cut-off line baffle 33, so that the light emitting areas of the far and near light sources are closer.

[0035] The lens bracket 40 includes a frame bracket body 40a and a bracket sleeve 40b extending away from the PCB board 20. The frame bracket body 40a is provided with a connection structure for connecting with the heat sink 10 to achieve a detachable connection with the heat sink 10. The bracket sleeve 40b is formed into a rectangular sleeve structure, and the lens 60 is connected to the end of the bracket sleeve 40b away from the PCB board 20 through a spring buckle 70.

[0036] When the vehicle is outdoors, sunlight can pass through the lens 60 and enter the inner side of the lens bracket 40. In order to increase the service life of the light source module, the inner side of the lens bracket 40 further includes a heat insulation board 50. Specifically, the heat insulation board 50 is located inside the bracket cover 40b and abuts against the bottom surface of the bracket cover 40b and the side surface adjacent to the bottom surface. The heat insulation board 50 can isolate light, so that the bracket cover 40b of the lens bracket 40 is kept in a relatively constant temperature range, thereby increasing its service life.

[0037] Specifically, the heat sink 10 includes a heat sink 10a and heat sink fins 10b located on one side of the heat sink 10a. The heat sink 10a is provided with a plurality of connection holes. The PCB board 20, the focusing assembly 30 and the lens bracket 40 are connected to the heat sink 10a.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
