Then, when the collimating lens assembly is aimed at the second light-emitting body and the lamp beads in the second light-emitting body are not all lit and the same lamp beads in each group of the second light-emitting bodies are lit, due to the different placement angles of the second light-emitting bodies, the placement angles of the light spots emitted by the lamp beads at different placement angles through the collimating lens assembly and the converging lens assembly will also be different, and the light spots at different placement angles overlap, which can better avoid the problem of eccentric light spots. Or, when the lamp beads in the second light-emitting body are lit at the same time, the same lamp beads are imaged at different positions of the preset plane, so that the angles and positions of the images of the lit lamp beads on the preset plane are different, which has the effect of homogenizing the light spots on the preset plane. In addition, since the gap spacing between the first compound eye lens and the second compound eye lens in the uniform light lens assembly of the technical solution is 0-0.7mm, the compound eye lens with a small gap spacing has a better homogenization effect on the light, so that a more uniform light spot can be obtained. The technical solution uses an eccentric deflection method, and the light source system has a small size and good stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0035] Example 1

[0036] like Figures 1 to 3As shown, this embodiment discloses a light source system, including: a light-emitting component 100 and a collimating lens component 200 for gathering and / or collimating light, a homogenizing lens component 300 for homogenizing light, and a converging lens component 400 for converging light, which are sequentially arranged along the light emitting direction of the light-emitting component 100, wherein the collimating lens component 200 includes a collimating lens bracket 210 and a lens unit arranged on the collimating lens bracket 210.

[0037] like Figure 4 , Figure 5 As shown, the light-emitting component 100 includes a substrate 110 and an array-arranged light-emitting body group 120 disposed on the substrate 110, the light-emitting body group 120 includes at least a first light-emitting body group 121 and a second light-emitting body group 122, the light-emitting body group 120 includes at least a first light-emitting body 101 and a second light-emitting body 102, wherein at least the second light-emitting body 102 is an N-in-one lamp bead, N≥2, the second light-emitting body 102 in the first light-emitting body group 121 and the second light-emitting body 102 in the second light-emitting body group 122 are placed at different angles, and when the second light-emitting body 102 in the second light-emitting body group 122 rotates around its center point, it can be placed at the same angle as the second light-emitting body 102 in the first light-emitting body group 121. Specifically, in this embodiment, the light-emitting body group 120 includes a first light-emitting body group 121, a second light-emitting body group 122, and a second light-emitting body group 123, and the light-emitting body group includes a first light-emitting body 101, a second light-emitting body 102, and a third light-emitting body 103, and the second light-emitting body 102 includes a four-in-one lamp bead. In other embodiments, the number of light-emitting body groups 120 can also be 2, 4, or more than 4, the number of light-emitting bodies can also be 2, 4, or more than 4, and the lamp beads of the second light-emitting body can also be 2, 3, 5, or more than 5. More specifically, in this embodiment, the second light-emitting body 102 in each group of light-emitting bodies is placed at a different angle from the second light-emitting body 102 in other groups of light-emitting body groups, and the second light-emitting body 102 in each group of light-emitting body groups 120 can be placed at the same angle as the second light-emitting body 102 in other groups of light-emitting body groups 120 when rotating around its center point.

[0038] The light homogenizing lens assembly 300 includes a first fly-eye lens 310 and a second fly-eye lens 320 which are parallel to each other and whose lens array surfaces are opposite to each other. The gap between the first fly-eye lens 310 and the second fly-eye lens 320 is 0-0.7 mm.

[0039] The light source system also includes an eccentric rotation mechanism 500, a support frame assembly 600 and a driving assembly 700 arranged on the substrate 110. The support frame assembly 600 is used to carry the collimating lens assembly 200 and is rotatably connected to the collimating lens bracket 210 via the eccentric rotation mechanism 500; the driving assembly 700 is used to drive the eccentric rotation mechanism 500 to move the collimating lens assembly 200 relative to the light-emitting assembly 100.

[0040] The light-emitting body group 120 of the light-emitting component 100 of the utility model includes a first light-emitting body 101, a second light-emitting body 102 and a third light-emitting body 103, and is provided with an eccentric rotation mechanism 500, a support frame assembly 600 and a driving assembly 700. The supporting frame assembly 600 is used to carry the collimating lens assembly 200, and is rotatably connected to the collimating lens bracket 210 through the eccentric rotation mechanism 500. The driving assembly 700 can move the collimating lens assembly 200 relative to the light-emitting component 100, so that the collimating lens assembly 200 can be aligned with different light-emitting bodies in the light-emitting component 100, so as to achieve the gathering and / or collimation of light from different light-emitting bodies, and the light collection efficiency is high. Since the second light-emitting body 102 is a 4-in-1 lamp bead, when the collimating lens assembly 200 is aligned with the second light-emitting body 102, the lens unit on the collimating lens assembly 200 is aligned with the center of the entire second light-emitting body 102, and any lamp bead in the second light-emitting body 102 is not aligned with the center of the lens unit on the collimating lens assembly 200. If it passes directly through the converging lens assembly 400, the shape of the emitted light spot is the same as the shape of the lamp bead and a certain degree of eccentricity will occur. In order to avoid the eccentricity, the technical solution sets the light-emitting body group 120 to include the first light-emitting body group 121, the second light-emitting body group 122 and the third reflector group 1 23, and the placement angle of the second light-emitting body 102 in each light-emitting body group 120 is different from that of the second light-emitting body 102 in other light-emitting body groups 120, and the second light-emitting body 102 in each light-emitting body group 120 can be consistent with the placement angle of the second light-emitting body 102 in other light-emitting body groups 120 when rotating around its center point, then the light spots emitted by the lit lamp beads in the second light-emitting bodies 102 with different placement angles through the converging lens assembly 400 are also eccentric light spots with different rotation angles, and these light spots will be superimposed in the focal plane, thereby improving the problem of eccentricity of the light spot and the same shape of the imaging as the lamp bead, thereby achieving the effect of homogenizing the light spot. Furthermore, the present technical solution is provided with a fly-eye lens assembly 300 capable of homogenizing light. The function of the fly-eye lens assembly 300 is to further homogenize parallel light or nearly parallel light to obtain more uniform parallel light. The present technical solution can further enhance the light homogenization effect of the fly-eye lens assembly 300 by setting the gap spacing between the first fly-eye lens 310 and the second fly-eye lens 320 to 0-0.7 mm. The reason is that for the first fly-eye lens 310 and the second fly-eye lens 320 which are parallel to each other and the lens array surfaces are arranged opposite to each other, when achieving the light homogenization effect, the smaller the gap spacing between the first fly-eye lens 310 and the second fly-eye lens 320 and the smaller the small lens unit (i.e., fly-eye lens unit) on the fly-eye lens, the better the light homogenization effect. The lens array surface described in the present application is only the plane where the apex of the convex part of the fly-eye lens is located. In addition, the present technical solution adopts an eccentric rotation method, the spacing between each light source can be small, the overall volume of the light source system is relatively small, and the movement stability is good.

[0041] Further, if Figure 10-12 As shown, the light homogenizing lens assembly 300 also includes a fly-eye lens bracket 330, the first fly-eye lens 310 and the second fly-eye lens 320 are installed on two opposite sides of the fly-eye lens bracket 330 and the gap between the two is 0.3-0.7 mm, the edge of the first fly-eye lens 310 and the edge of the second fly-eye lens 320 are both provided with a convex edge 301 protruding from the edge, and the projection of the convex edge 301 of the first fly-eye lens 310 and the convex edge 301 of the second fly-eye lens 320 on the lens array surface of the first fly-eye lens 310 is misaligned; both sides of the fly-eye lens bracket 330 are provided with a plurality of mounting grooves 331 that cooperate with the convex edge 301. For the movement mode of the collimating lens assembly relative to the light-emitting assembly, the present technical solution adopts an eccentric rotation mode, and the light source system is small in size and has good stability. And when the number of light-emitting bodies in the light-emitting body group 120 exceeds 2, this eccentric rotation method can make the maximum spacing between the light-emitting bodies smaller, and can reduce the maximum offset of the optical axis of the collimating lens assembly 200 relative to the optical axis of the converging lens assembly 400.

[0042] In this embodiment, the structures and shapes of the fly-eye lens holder 330 and the first fly-eye lens 310 and the second fly-eye lens 320 are improved, and convex edges 301 are set on the edges of the first fly-eye lens 310 and the edges of the second fly-eye lens 310, and the projections of the convex edges 301 of the first fly-eye lens 310 and the convex edges 301 of the second fly-eye lens 320 on the array surface of the first fly-eye lens 310 are staggered. Both sides of the fly-eye lens holder 330 are provided with a plurality of mounting grooves 331 that cooperate with the convex edges 301, so that the mounting grooves 331 on both sides of the fly-eye lens holder 330 can be staggered with each other. Compared with the design of symmetrically setting the mounting grooves 331 on both sides, this staggered design can reduce the distance between the two fly-eye lenses while ensuring that the thickness of the entire fly-eye lens holder 330 is not greatly affected. That is, this embodiment can ensure the strength and thickness of the fly-eye lens bracket 330 on the one hand, and reduce the distance between the first fly-eye lens 310 and the second fly-eye lens 320 on the other hand, so that the number of fly-eye lens units on the first fly-eye lens 310 and the second fly-eye lens 320 can be set to be sufficient to ensure the homogenization effect of the light beam, thereby ensuring the light output effect of the light source system.

[0043] Furthermore, if Figure 1 , Figure 2 , Figure 3 , Figure 7As shown, the eccentric rotation mechanism 500 includes a first deflection connecting member 510 and a second deflection connecting member 520, the first deflection connecting member 510 includes a first rotating shaft 501 and a second rotating shaft 502 which are arranged in parallel but not coaxially, the first rotating shaft 501 is rotatably connected to the collimating lens bracket 210, the second rotating shaft 502 is rotatably connected to the support frame assembly 600, the second deflection connecting member 520 includes a third rotating shaft 503 and a fourth rotating shaft 504 which are arranged in parallel but not coaxially, the third rotating shaft 503 is rotatably connected to the collimating lens bracket 210, and the fourth rotating shaft 504 is rotatably connected to the support frame assembly 600. Since the first rotating shaft 501 is rotatably connected to the collimating lens bracket 210, the second rotating shaft 502 is rotatably connected to the support frame assembly 600, and the first rotating shaft 501 and the second rotating shaft 502 are not coaxially arranged, when the second rotating shaft 502 rotates, it will drive the first rotating shaft 502 to rotate, thereby causing the collimating lens assembly 200 to rotate eccentrically relative to the second rotating shaft 502, that is, to achieve the rotational movement of the collimating lens assembly 200. The second deflection connecting member can make the rotational movement of the collimating lens assembly 200 more stable. Further, in this embodiment, the number of the second deflection connecting members 520 is 2, and in other embodiments, the number of the second deflection connecting members 520 can also be 1 or 3 or more than 3. In particular, in this embodiment, the luminous body group 120 includes three luminous bodies, namely, the first luminous body 101, the second luminous body 102, and the third luminous body 103, and the three luminous bodies are arranged in a circular arc, and the spacing between the first rotating shaft 501 and the second rotating shaft 502 is equal to the radius of the circular arc. More specifically, in this embodiment, the three luminous bodies are arranged in an equilateral triangle, that is, the three luminous bodies are evenly distributed on a circle. If the three luminous bodies are arranged in a straight line, the distance between the center points of two adjacent luminous bodies is d1, and the collimating lens assembly moves in a straight line, the initial position of the collimating lens mechanism is to align with the middle luminous body, then when the collimating lens assembly needs to align with the luminous bodies on both sides, the distance that the collimating lens assembly needs to move relative to the initial position is d1. Using the technical solution of this embodiment, if the distance between the center points of two adjacent luminous bodies of the three luminous bodies is also d1, and the initial position of the collimating lens assembly is to align with the center of the circle where the three luminous bodies are located, then relative to the initial position, when the collimating lens assembly needs to align with any luminous body, the distance that the collimating lens assembly needs to move is about 0.577d1, which shows that the maximum distance of the collimating lens assembly relative to the initial position is smaller, so compared with the linear arrangement, the maximum offset of the optical axis of the collimating lens assembly relative to the optical axis of the converging lens assembly is smaller, the optical extension loss of the light source system is small, and the light output efficiency is high.

[0044] Furthermore, if Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, the support frame assembly 600 includes a first support frame 610 with a first through hole 611 and a second support frame 620 with a second through hole 621, the second shaft 502 is inserted into the first through hole 611, and the fourth shaft 504 is inserted into the second through hole 621. In this embodiment, the first support frame 610 and the second support frame 620 are independent structures. In other embodiments, the first support frame 610 and the second support frame 620 can also be integrally formed, for example, the first support frame 610 and the second support frame 620 are both parts of a larger support frame. The support frame assembly 600 is disposed on the substrate 110.

[0045] Preferably, bearings are further provided in the first through hole 611 and the second through hole 621, and the second rotating shaft 502 and the fourth rotating shaft 504 are both inserted into the bearings. The design of the bearings can make the rotational motion smoother.

[0046] Further, the driving assembly 700 includes a driving member 710 and a transmission member 720 connected to an output end of the driving member 710, and the first deflection connecting member 510 is connected to the transmission member 720. More specifically, in this embodiment, the output end is a worm.

[0047] Furthermore, the transmission member 720 is a worm gear, and the second rotating shaft 502 of the first deflection connecting member 510 is located at the center of the turbine, and the rotating shaft of the turbine coincides with the second rotating shaft 502. When the worm rotates, it drives the turbine to rotate, and then the second rotating shaft 502 rotates, thereby driving the first rotating shaft 501 to rotate, and realizing the rotational movement of the collimating lens bracket 210.

[0048] Furthermore, in this embodiment, a mounting frame 730 for supporting and mounting the driving member 710 is also provided.

[0049] Furthermore, a card interface 721 is provided at the center of the worm gear, and the first eccentric connecting member 510 includes a card post 5021 matching the card interface 721, and the card post 5021 rotates when the turbine rotates. More specifically, in this embodiment, the card post 5021 is a part of the second rotating shaft 502 and is located at an end away from the first rotating shaft 501. When the turbine drives the card post 5021 to rotate, it drives the first deflection connecting member 510 to rotate, and then drives the collimating lens bracket 210 to rotate. More specifically, the card interface 721 of this embodiment is set as a circular segment-shaped through hole or a circular segment-shaped notch, and accordingly, the cross-section of the card post 5021 is a circular segment-shaped matching the card interface 721.

[0050] Furthermore, if Figures 1 to 3 , Fig. 9As shown, the light source system also includes a limit assembly 800 for limiting the rotation of the collimating lens assembly 200. Further, in this embodiment, the limit assembly 800 includes three ball plungers 810 arranged on the support frame assembly 600 and positioning holes 820 arranged on the collimating lens bracket 210 and matching the ball plungers 810; the number of the ball plungers 810 is the same as the number of light-emitting bodies in the same light-emitting body group, and the positioning holes 820 are arranged on the movement trajectory of the ball plungers 810, and when the ball plungers 810 are respectively inserted into different positioning holes 820, the lens units on the collimating lens assembly 200 are respectively aligned with different light-emitting bodies. In other embodiments, the ball plunger 810 can also be arranged on the collimating lens bracket 210, and the positioning hole 820 can be arranged on the support frame assembly 600. The ball plunger can be a conventional structure sold on the market, which will not be repeated here.
