[0033] DETAILED DESCRIPTION

[0034] The present invention is 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 are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0035] Embodiment 1:

[0036] like Figure 1 The schematic diagram of the structure of the headlight module for a motor vehicle is shown as follows: Figure 2 The light path schematic diagram of the headlamp module for a motor vehicle is shown, including a module unit, the module unit is provided with one or more, and the module unit is configured to form a light projection 5. In this embodiment, the number of module units is N, where N=1, 2, 3, 4 or greater than 4. The module unit includes a light source 2, a primary optical element 3 and a secondary optical element 4, the primary optical element 3 is arranged corresponding to the light source 2, and the primary optical element 3 and the secondary optical element 4 are arranged correspondingly. The light source 2 is fixedly arranged on a circuit board 1, and the circuit board 1 adopts a PCB board. In this embodiment, the center line of the primary optical element 3 and the center line of the secondary optical element 4 are arranged to coincide with each other. The primary optical element 3 includes an optical unit that can be individually controlled to light up and down, and the optical unit is provided with one or more, and the one or more optical units adopt the same optical configuration. The light emitted by the light source 2 is focused by the primary optical element 3, and the focused light forms a light projection 5 through the secondary optical element 4.

[0037] The light projection 5 is composed of one or more projection units, and the projection units include a first projection unit S30, a second projection unit S31, etc. The first projection unit S30, the second projection unit S31, etc. are configured to be at the same height, and their upper edges and lower edges are configured to be respectively on the same straight line, and there is no interval between adjacent projection units. The module unit is configured to be able to move in the horizontal or vertical direction from the initial position, so that the light projections 5 corresponding to the single module unit overlap each other.

[0038] The primary optical element 3 includes a first optical unit 30 and a second optical unit 31, and the first optical unit 30 and the second optical unit 31 are arranged in sequence, for example, Figure 2 As shown, the primary optical element 3 includes 5 optical units, and the size of the light projection 5 will have different display conditions according to the different number of optical units. The first optical unit 30 and the second optical unit 31 are arranged at the same reference height, and the upper and lower edges of the light projection 5 formed by the multiple optical units are on the same straight line, and the adjacent edges of the light projection 5 are connected to each other to form a complete light projection 5.

[0039] like Figure 3 The secondary optical element 4 is shown as a schematic diagram of the structure of the secondary optical element. The light incident surface or the light emitting surface of the secondary optical element 4 is provided with the following Figure 3 The microstructure pattern shown can disperse the emitted light, so that when the first optical unit 30 (when the number of second optical units is greater than 2) on the primary optical unit, the presence of the microstructure pattern can prevent obvious dark areas or bright lines from appearing at the joints of the projection units, so that the entire light projection 5 appears in a uniform state.

[0040] One or more optical units form light projections 5 of different sizes, and the width of the light projection 5 is set in proportion to the number of primary optical units. In one embodiment, Figure 4 FIG. 5 is a schematic diagram of light projection 5 generated by two optical units. Figure 5 FIG. 5 is a schematic diagram of a light projection 5 generated by an optical unit, wherein the horizontal width of the one or more optical units can be varied, for example Figure 4 and Figure 5 As shown, the widths are 2w and w respectively. Each projection can be controlled to light up or turn off separately.

[0041] A light projection 5 of a given shape can be projected as required, and the primary optical element 3 forming the projection can also be formed by a plurality of independent first optical units 30 and second optical units 31 arranged in sequence. The light projection 5 includes a plurality of regional light patterns, and the minimum width of a single regional light pattern is 15 mm, and the minimum length of a single regional light pattern is 30 mm. Figure 6 Shown is a schematic diagram of the projection of the module unit, which is a shape of the adaptive high beam and low beam light projection 5 formed by the headlight module of the present invention in one case, wherein the projection unit (S30, S31...) is formed by the projection of the module unit P1, and the projection unit (S30', S31'...) is formed by the projection of the module unit P2.

[0042] like Figure 6 As shown, the position of the light projection 5 projected by the module unit can be displaced according to the resolution requirement. The module unit P2 is displaced by l in the horizontal direction relative to the module unit P1, so the minimum controllable pixel of the light projection 5 in the horizontal direction is l; similarly, the module unit P2 can also be displaced in the vertical direction relative to the module unit P1, or the module unit P2 can be displaced in both the horizontal and vertical directions relative to the module unit P1, so as to meet different pixel requirements.

[0043] Embodiment 2:

[0044] The second embodiment is formed on the basis of the first embodiment. The primary optical element 3 is set in an integrated structure. The optical element 3 forming the regional light pattern can be an integrated structure. Its advantages are high positioning accuracy and smoother connection between regional light patterns.

[0045] In the projection area where the pixel requirements are not high, the primary optical element 3 can be set to two or more according to the actual application requirements, forming a light projection 5 with a width of 2w to nw, thereby avoiding dark areas caused by the poor connection between the light types of each area; for areas with higher pixel requirements, the number of module units can be set to two or more, so that two or more light projections 5 can overlap with each other, forming an adaptive light projection 5 of a part of the high beam or low beam, thereby improving its resolution, and then any desired light type combination can be generated.
