[0036] DETAILED DESCRIPTION OF THE INVENTION

[0037] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all belong to the protection scope of the present invention.

[0038] The present invention provides a light source mounting structure for a vehicle lamp module. Referring to Figures 1 to 8 as shown, it includes: a main light source assembly 9, a replaceable light source assembly 14, and a front lens assembly 4; the replaceable light source assembly 14 is detachably installed with the main light source assembly 9, and is connected to the replaceable light source assembly 14 through a connecting member on one side of the main light source assembly 9; the light output ports of the main light source assembly 9 and the replaceable light source assembly 14 are arranged side by side and connected to the light input port of the front lens assembly 4.

[0039] The main light source assembly 9 includes: a main light source circuit board 6, a main light source radiator 5, and a main light source reflector bowl 7; a light source is provided on the main light source circuit board 6, and the light source can be an LED light source or a laser light source; during installation, apply thermal conductive glue on the back of the main light source circuit board 6, place it on the main light source radiator 5, then place the main light source reflector bowl 7 on the main light source circuit board 6, and finally pass screws 8 through the main light source reflector bowl 7 and the main light source circuit board 6 in sequence and lock them on the main light source radiator 5 to form the main light source assembly 9. The light generated by the light source on the main light source circuit board 6 is reflected by the main light source reflector bowl 7 and exits from the front lens assembly 4. A main light source light blocking sheet 503 is provided on the main light source radiator 5 at the light output end.

[0040] The replaceable light source assembly 14 includes a replaceable light source radiator 10, a replaceable light source reflector bowl 12, a replaceable light source circuit board 13, and a replaceable light source light blocking sheet 11; the replaceable light source reflector bowl 12 and the replaceable light source circuit board 13 are fixed on the replaceable light source radiator 10, and are locked on the replaceable light source radiator 10 by passing screws 8 through the replaceable reflector bowl and the replaceable light source circuit board 13 in sequence. At the light output port of the replaceable light source radiator 10 near the replaceable light source reflector bowl, a light blocking sheet positioning post 104 and a light blocking sheet riveting post 105 are provided. Place the replaceable light source light blocking sheet 11 in the light blocking sheet positioning post 104 of the replaceable light source radiator 10, and fix the replaceable light source light blocking sheet 11 by machine-pressing the riveting post.

[0041] The front lens assembly 4 includes a lens buckle 1, a lens 2, and a lens bracket 3. The lens buckle 1, the lens 2, and the lens bracket 3 are stacked and installed to form the front lens assembly 4. The front lens assembly 4 is fixedly connected to the main light source radiator 5 by screws 8. The main light source radiator 5 has a lateral mounting point, enabling a replaceable light source to be installed on the main light source radiator 5, thereby ensuring that the light outlet of the replaceable light source assembly 14 is aligned with the front lens assembly 4.

[0042] On the side of the main light source radiator 5, there are a replaceable light source positioning post 501 and a replaceable light source mounting screw post 502. On the side of the replaceable light source radiator 10, there are a positioning arc groove 101 and an arc-shaped hole 102. During installation, the positioning arc groove 101 is pushed onto the replaceable light source positioning post 501, and the replaceable light source mounting screw post 502 is located within the arc-shaped hole 102. The replaceable light source assembly 14 rotates around the replaceable light source positioning post 501. There are two arc-shaped grooves, and their shapes match the movement path of the replaceable light source mounting screw post 502 on the replaceable light source radiator 10. After adjustment, it is fixed by a locking screw. The replaceable light source light shield 11 cuts off the emitted light of the replaceable light source assembly 14. By rotating the replaceable light source assembly 14, the light reflected from the replaceable light source light shield 11 to the front will also rotate, thereby adjusting the up and down position of the final light pattern emerging from the lens. Thus, the light pattern of the replaceable light source assembly 14 is calibrated to align with the cut-off line light pattern of the main light source.

[0043] In this embodiment, the light source is set as a surface-mount LED, which is integrated on the PCBA or on the radiator and is connected to the PCB board through metal wires. In other embodiments, other light source types can be selected according to actual needs.

[0044] The present invention can be configured to generate multiple light distributions. The types between the multiple light distributions are different, and each light distribution type is any one of the following: low beam illumination, high beam illumination, adaptive low beam illumination, ADB high beam illumination, corner fog lamp illumination, urban road mode illumination, rural road mode illumination, highway mode illumination, curve mode illumination, rain and fog mode illumination, position signal lamp, turn signal lamp, daytime running lamp, welcome lamp, ambient lamp, etc.

[0045] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.
