Description

Technical Field

[0001] This application relates to the field of optical instrument technology, and in particular to a multi-light source adjustment device and optical equipment. Background Technology

[0002] The emergence of high-brightness LED devices has provided new possibilities for the long lifespan and miniaturization of modern light source systems. However, due to the differences in the shape and luminous characteristics of LEDs compared to traditional light sources, LEDs cannot be directly applied to many lighting systems. In existing technologies, integrating tubes, compound eyes, or collimating lenses are typically used to ensure that the light emitted by the LED is uniformly irradiated onto the device to be illuminated. At the same time, in order to obtain higher optical efficiency of LEDs, it is necessary to adjust the center of the LED's luminous surface to be located at the axis of the modulation devices such as integrating tubes, compound eyes, and collimating lenses.

[0003] However, for applications requiring multi-wavelength light sources, such as a current market light source product that packages four light source patches (red, green, blue, and white) onto a single PCB board and adds a collimating lens to achieve collimated light output, the optical efficiency is low when using a single-color light source because the center of the collimating lens coincides with the center of the entire PCB board and is not at the center of the emitting surface of any of the four light source patches.

[0004] Therefore, there is a need to provide an improved multi-light source adjustment device to solve at least one of the aforementioned problems in the prior art. Summary of the Invention

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0048] The embodiments are described below with reference to the accompanying drawings, which do not limit the scope of the invention as described in the claims.

[0049] Please refer to Figure 1-9This application provides a multi-light source adjustment device, including an optical path assembly 1, a light source assembly 2, and an adjustment assembly 3. The optical path assembly 1 is disposed on the outgoing light path of the light source assembly 2. The optical path assembly 1 includes a lens barrel 11. The light source assembly 2 includes at least two light sources 22 and a light source carrier 21. The at least two light sources 22 are distributed on the light source carrier 21. The adjustment assembly 3 is fixedly connected to the light source carrier 21, and one end of the adjustment assembly 3 is connected to the lens barrel 11. The adjustment assembly 3 can adjust the relative position between the light source carrier 21 and the lens barrel 11, thereby adjusting the light emission center of any one of the at least two light sources 22 to be aligned with the optical axis of the lens barrel 11, while making the outgoing light spot projected by the light source 22 cover the area to be illuminated.

[0050] Thus, in this embodiment, at least two light sources 22 are distributed on the light source carrier 21. The light source carrier 21 is fixed on the adjusting assembly 3, and one end of the adjusting assembly 3 is fixed on the lens barrel 11. The adjusting assembly 3 can drive the light source carrier 21 to move relative to the lens barrel 11, thereby adjusting the light emission center of any one of the at least two light sources 22 to be aligned with the optical axis of the lens barrel 11. This allows the center of the light emission surface of any one of the light sources 22 to be adjusted to be coaxial with the optical axis of the lens barrel 11. This improves the optical efficiency of the light output of the required light source without replacing the high-power light source. Moreover, the multi-light source adjustment device has a simple and compact structure and is easy to operate.

[0051] Specifically, such as Figure 5 As shown, the light source carrier 21 can be a PCB circuit board, and the light source can be an LED light source patch. The LED light source patch can be soldered onto the PCB circuit board, and then the LED light source patch emits light when the PCB circuit board is connected to an external power supply.

[0052] In some embodiments, at least two light sources 22 include light sources of at least two wavelengths.

[0053] It should be noted that different wavelengths of light correspond to different colors, so at least two colors of light source 22 can be set on the light source carrier 21.

[0054] In some embodiments, four colors of light sources 22 are arranged on the light source carrier 21.

[0055] In this embodiment, by arranging at least two colors of light sources 22 on the light source carrier 21, the light source carrier 21 can be moved relative to the lens barrel 11 by the core adjustment assembly 3, thereby adjusting the center of the emitting surface of the light source 22 of different colors to be aligned with the optical axis of the lens barrel 11, and at the same time making the emitted light spot projected by the light source 22 cover the area to be illuminated, it can be ensured that the light spot is projected to the correct position, thereby improving the optical efficiency of the light output of the light source 22 of the required color.

[0056] In other embodiments, two light sources 22 of the same color are arranged on the light source carrier 21. In the event that one of the two light sources 22 of the same color fails, the center of the emitting surface of the other light source 22 can be aligned with the optical axis of the lens barrel 11 by the core adjustment assembly 3, and the projected light spot covers the area to be illuminated, thereby improving the reliability and adjustment efficiency of the adjustment device.

[0057] like Figure 4 As shown, in some embodiments, the adjusting assembly 3 includes a first adjusting member 31, a second adjusting member 32, and a third adjusting member 33. The light source carrier 21 is fixedly connected to the first adjusting member 31. The first adjusting member 31 is connected to the second adjusting member 32, and the first adjusting member 31 can move relative to the second adjusting member 32 in a first direction. The second adjusting member 32 is connected to the third adjusting member 33, and the second adjusting member 32 can move relative to the third adjusting member 33 in a second direction in coordination with the first adjusting member 31. The first direction and the second direction intersect. The third adjusting member 33 is connected to the lens barrel 11, and the third adjusting member 33 can move relative to the lens barrel 11 in a third direction in coordination with the first adjusting member 31 and the second adjusting member 32 to adjust the relative distance between the light source carrier 21 and the lens barrel 11.

[0058] Specifically, such as Figure 7 As shown, the first adjusting member 31 is provided with a light source connection position 315. The light source carrier 21 can be fixed to the light source connection position 315 by bolt connection, for example by clamping screw, or by adhesive.

[0059] Specifically, to ensure the mounting flatness of the light source carrier 21 on the first adjusting member 31, the light source connection position 315 can be a precision-machined surface.

[0060] Specifically, to facilitate the electrical connection between the external power supply and the light source carrier 21, the first adjusting member 31 is also provided with a clearance structure 313, through which the power supply wire can be connected to the light source carrier 21.

[0061] Specifically, such as Figure 3 As shown, the second adjusting member 32 is disposed between the first adjusting member 31 and the third adjusting member 33, and the second adjusting member 32 is provided with a first optical path through hole 323, and the third adjusting member 33 is provided with a second optical path through hole 333, thereby enabling the light-emitting optical path of the light source 22 disposed on the first adjusting member 31 to be connected.

[0062] Specifically, such as Figure 7-9As shown, the first adjusting member 31 is also provided with a first connecting part 314, the second adjusting member 32 is provided with a second connecting part 325 and a second connecting structure 324, and the first connecting part 314 and the second connecting structure 324 can be detachably connected by bolts. The third adjusting member 33 is provided with a third connecting structure 334, and the second connecting part 325 and the third connecting structure 334 can be detachably connected by bolts.

[0063] In some embodiments, the light source 22 satisfies at least one of the following conditions: the light source 22 is a non-circular or non-spherical light source patch, meaning the emitted light from the light source 22 is non-circular; the emitting surface of the light source 22 is non-circular; and the working light spot generated after the emitted light from the light source 22 is modulated by the optical path assembly 1 is non-circular. Thus, when the emitted light from the non-circular or non-spherical light source patch, or the non-circular emitting surface, or the non-circular working light spot has an inconsistency in angle with the area to be illuminated, the light spot projected onto the area to be illuminated cannot completely cover the area, thereby reducing the optical efficiency of the monochromatic light source. In this embodiment, the light source is a rectangular or square light source patch, meaning the emitting surface of the light source 22 is rectangular or square. In other embodiments, the light source may also have other shapes, such as a circle.

[0064] Specifically, such as Figure 2 and 3 As shown, the lens barrel 11 is provided with a guide shaft section 112, and an adjustable clamping member 331 is sleeved on the guide shaft section 112. The third adjusting member 33 is also provided with a guide shaft mating part 335, which is provided on the connecting body 332, and the guide shaft section 112 can move within the guide shaft mating part 335. By adjusting the adjustable clamping member 331, the third adjusting member 33 can move relative to the lens barrel 11 in a third direction to adjust the relative distance and relative angle between the light source carrier 21 and the lens barrel 11, thereby improving the uniformity of the area to be illuminated. At the same time, it ensures that the emitted light spot projected by the light source 22 can completely cover the area to be illuminated, ensuring that the light spot is projected to the correct position. It can improve the optical efficiency of the required light source output without replacing the high-power light source, and it can adapt to light sources 22 with various shapes and structures. Preferably, the guide shaft mating part 335 is a guide shaft mating cavity, and the guide shaft section 112 is embedded in the guide shaft mating cavity and can move and rotate freely, that is, the inner diameter of the guide shaft mating cavity is slightly larger than the outer diameter of the guide shaft section 112.

[0065] In some embodiments, such as Figure 2 As shown, the distance from the inner wall of the guide shaft section 112 and the inner wall of the guide shaft mating part 335 to the optical axis is greater than or equal to the distance from the inner wall of the second adjusting member 32 to the optical axis, so as to ensure that the working light emitted from the light source assembly 2 is smoothly projected into the optical path assembly 1.

[0066] In some embodiments, such as Figure 7-9 As shown, the first connecting part 314 can be a first waist-shaped groove, and the second connecting structure 324 can be a first threaded hole. Then, the second adjusting member 32 is fixed on the first adjusting member 31 by means of a bolt passing through the first waist-shaped groove and threadedly connecting with the first threaded hole. The second connecting part 325 can be a second waist-shaped groove, and the third connecting structure 334 can be a second threaded hole. Then, the third adjusting member 33 is fixed on the second adjusting member 32 by means of a bolt passing through the second waist-shaped groove and threadedly connecting with the second threaded hole. The length direction of the first waist-shaped groove is perpendicular to the length direction of the second waist-shaped groove. The guide shaft mating part 335 can be sleeved on the guide shaft section 112 of the lens barrel 11, and the guide shaft mating part 335 can move along the axial direction of the guide shaft section 112, thereby adjusting the relative distance between the light source carrier 21 and the lens barrel 11.

[0067] Based on some or all of the above embodiments, in this application embodiment, the first waist-shaped groove and the second waist-shaped groove can be set to the same size, and the first threaded hole and the second threaded hole can be set to the same size, so as to improve the assembly efficiency between the first adjusting member 31, the second adjusting member 32 and the third adjusting member 33.

[0068] In some embodiments, the first adjusting member 31 can be an X-axis adjusting member, the second adjusting member 32 can be a Y-axis adjusting member, and the third adjusting member 33 can be a Z-axis adjusting member. The movement direction of the X-axis adjusting member is perpendicular to the movement direction of the Y-axis adjusting member, and the movement direction of the Z-axis adjusting member is parallel to the optical axis of the lens barrel 11. By sequentially adjusting the X-axis adjusting member, the Y-axis adjusting member, and the Z-axis adjusting member, the relative position between the light source carrier 21 on the X-axis adjusting member and the lens barrel 11 can be adjusted, so that the center of the emitting surface of any one of the at least two wavelength light sources 22 on the light source carrier 21 is adjusted to be coaxial with the optical axis of the lens barrel 11, thereby improving the optical efficiency of the output light of any desired light source 22.

[0069] In this embodiment, the first direction can correspond to the X-axis direction, the second direction can correspond to the Y-axis direction, and the third direction can correspond to the Z-axis direction.

[0070] In this embodiment, the third adjusting member 33 is connected to the lens barrel 11. The third adjusting member 33 can move and rotate relative to the lens barrel 11, so that the center of the emitting surface of any wavelength light source 22 is adjusted to be coaxial with the optical axis of the lens barrel 11, and the emitted light spot can cover the area to be illuminated, thereby improving the optical efficiency of the output light of any desired light source 22. In other embodiments, the third adjusting member 33 is connected to the lens barrel 11, and the third adjusting member 33 can move or rotate relative to the lens barrel 11.

[0071] In this embodiment, the third adjusting member 33 can rotate relative to the lens barrel 11 about a third direction, and then the second adjusting member 32 can work together to drive the light source carrier 21 on the first adjusting member 31 to rotate relative to the lens barrel 11 about a third direction. This allows the working light spot projected onto the area to be illuminated by the emitting surface of any light source 22 on the light source carrier 21 to completely cover the area to be illuminated, thereby improving the optical efficiency of the output light of any desired light source 22.

[0072] In some embodiments, such as Figure 7-9 As shown, one of the first adjusting member 31 and the second adjusting member 32 is provided with a first guide shaft 311, and the other is provided with a first limiting groove 312 that cooperates with the first guide shaft 311; the first guide shaft 311 can move in a first direction within the first limiting groove 312; one of the second adjusting member 32 and the third adjusting member 33 is provided with a second guide shaft 321, and the other is provided with a second limiting groove 322 that cooperates with the second guide shaft 321; the second guide shaft 321 can move in a second direction within the second limiting groove 322.

[0073] In some embodiments, the first adjusting member 31 is provided with a first limiting groove 312, the second adjusting member 32 is provided with a first guide shaft 311, the first guide shaft 311 can slide within the first limiting groove 312, the second adjusting member 32 is also provided with a second limiting groove 322, and the third adjusting member 33 is provided with a second guide shaft 321, the second guide shaft 321 can slide within the second limiting groove 322, and the sliding direction of the second guide shaft 321 is perpendicular to that of the first guide shaft 311.

[0074] Specifically, the first limiting groove 312 can be a first sliding groove, and the second limiting groove 322 can be a second sliding groove.

[0075] In this embodiment, by providing a first limiting groove 312 on the first adjusting member 31 and a first limiting groove 312 that slides with the first guide shaft 311 on the second adjusting member 32, the light source 22 on the first adjusting member 31 can be driven to move along the first limiting groove 312. By providing a second limiting groove 322 on the second adjusting member 32 and a second limiting groove 322 and a second guide shaft 321 that slides with the second limiting groove 322 on the third adjusting member 33, the second adjusting member 32 can be driven to move along the second limiting groove 322, thereby adjusting the light emission center of any light source 22 on the first adjusting member 31 to move with the optical axis of the lens barrel 11.

[0076] In other embodiments, the second adjusting member 32 is provided with a first limiting groove 312, the first adjusting member 31 is provided with a first guide shaft 311, the first guide shaft 311 can slide within the first limiting groove 312, the third adjusting member 33 is also provided with a second guide shaft 321, the second adjusting member 32 is provided with a second limiting groove 322, the second guide shaft 321 can slide within the second limiting groove 322, and the sliding direction of the second guide shaft 321 is perpendicular to that of the first guide shaft 311.

[0077] In other embodiments, the first adjusting member 31 is provided with a first limiting groove 312, the second adjusting member 32 is provided with a first guide shaft 311, the first guide shaft 311 can slide within the first limiting groove 312, the second adjusting member 32 is also provided with a second guide shaft 321, the third adjusting member 33 is provided with a second limiting groove 322, the second guide shaft 321 can slide within the second limiting groove 322, and the sliding direction of the second guide shaft 321 is perpendicular to that of the first guide shaft 311.

[0078] In some embodiments, such as Figure 8 As shown, the third adjusting member 33 includes an adjustable clamping member 331 and a connecting body 332; the adjustable clamping member 331 is sleeved on the lens barrel 11, and the adjustable clamping member 331 is fixedly connected to the connecting body 332. By adjusting the relative position relationship between the adjustable clamping member 331 and the lens barrel 11, the third adjusting member 33 can be driven to move relative to the lens barrel 11 in a third direction.

[0079] Specifically, the adjustable clamp 331 and the connecting body 332 can be fixedly connected by bolts or by welding as an integral connection, such as a welded integral connection or integral machining, which can improve the assembly efficiency of the third adjusting member 33 and the lens barrel 11.

[0080] Specifically, the adjustable clamp 331 can be a hose clamp.

[0081] Specifically, the connecting body 332 is connected and cooperates with the second adjusting member 32, and the adjustable clamping member 331 is connected and cooperates with the lens barrel 11.

[0082] Specifically, the adjustable clamp 331 has an adjusting connection 3311. The tightness of the connection between the adjustable clamp 331 and the lens barrel 11 can be adjusted by adjusting the adjusting connection 3311, so that the adjustable clamp 331 can drive the third adjusting member 33 to move and rotate relative to the lens barrel 11 in a third direction by adjusting the adjusting connection 3311, thereby adjusting the relative positional relationship between the third adjusting member 33 and the lens barrel 11, thereby coordinating and adjusting the relative positional relationship between the light source carrier 21 and the lens barrel 11.

[0083] In this embodiment, an adjustable clamping member 331 is provided on the third adjusting member 33. The adjustable clamping member 331 is sleeved on the guide shaft section 112 of the lens barrel 11, preventing the adjustable clamping member 331 from moving in the first and second directions, so that it only moves along the optical axis direction, i.e., the third direction, and rotates around the optical axis direction. By adjusting the adjustable clamping member 331, the relative positional relationship between the third adjusting member 33 and the lens barrel 11 can be adjusted, thereby coordinating and adjusting the relative distance between the light source carrier 21 and the lens barrel 11, thereby improving the uniformity of the emitted light spot projected by the light source 22 onto the area to be illuminated.

[0084] In some embodiments, the adjustable clamp 331 is sleeved on the lens barrel 11, and by adjusting the relative position of the adjustable clamp 331 and the lens barrel 11, the third adjusting member 33 can be driven to rotate relative to the lens barrel 11.

[0085] In some embodiments, such as Figure 4 As shown, there is a gap 336 between the adjustable clamp 331 and the connecting body 332. The adjustable clamp 331 can move relative to the connecting body 332 through the gap 336, so that the adjustable clamp 331 has adjustable elasticity relative to the rigid connecting body 332, thereby adjusting the tightness between the adjustable clamp 331 and the lens barrel 11, and further adjusting the positional relationship between the third adjusting member 33 and the lens barrel 11.

[0086] In this embodiment, the guide shaft section 112 is placed within at least a portion of the guide shaft mating part 335, meaning that the projection of the guide shaft section 112 onto the horizontal plane where the optical axis is located coincides with that of at least a portion of the guide shaft mating part 335. Thus, when adjusting the relative position between the third adjusting member 33 and the lens barrel 11, the adjustable clamping member 331 is loosened. Because the guide shaft section 112 is placed within at least a portion of the guide shaft mating part 335, the guide shaft mating part 335 can bear part of the weight of the lens barrel 11. This avoids the problem of reduced reliability or even damage to the connection between the adjustable clamping member 331 and the connecting body 332 due to concentrated force on the lens barrel 11 caused by the gap 336, further improving the stability of the connection between the lens barrel 11 and the third adjusting member 33.

[0087] In this embodiment, the adjustable clamp 331 is specifically designed so that after the adjustable connecting part 3311 is locked, the adjustable clamp 331 is engaged with the guide shaft section 112, and its inner diameter is smaller than the inner diameter of the guide shaft engaging part 335. This ensures a reliable fixed connection between the adjustable clamp 331 and the lens barrel 11. Optionally, the inner diameter of the adjustable clamp 331 is slightly smaller than the inner diameter of the guide shaft engaging part 335.

[0088] In this embodiment, by adjusting the tightness of the adjustable clamp 331 and the lens barrel 11, the rotation of the third adjusting member 33 relative to the lens barrel 11 is adjusted, which in turn drives and adjusts the rotation of the light source carrier 21 relative to the lens barrel 11, thereby adjusting the emitted light spot of any light source 22 on the first adjusting member 31 to coincide with the area to be illuminated.

[0089] In some embodiments, such as Figure 6 As shown, the optical path assembly 1 also includes at least one optical lens 12; the inner cavity of the lens barrel 11 accommodates at least one optical lens 12.

[0090] Specifically, the inner cavity of the lens barrel 11 is provided with at least one lens mounting position 111, and the optical lens 12 is fixedly installed in the lens mounting position 111.

[0091] Specifically, the lens mounting position 111 has an abutment shoulder structure, and the optical lens 12 can be accommodated in the lens mounting position 111 and abut against the abutment shoulder structure.

[0092] In this embodiment, by providing a lens mounting position 111 in the inner cavity of the lens barrel 11, the optical lens 12 can be fixedly housed within the lens mounting position 111, providing a fixed mounting position for the optical lens 12. The abutment shoulder structure ensures the installation stability of the optical lens 12 within the lens barrel 11, and improves the stability and accuracy of the optical path assembly 1 in adjusting the light emitted by the light source 22.

[0093] In some embodiments, such as Figure 6 As shown, the optical path assembly 1 also includes at least one pressure ring 13 for pressing the optical lens 12; at least one connecting part 113 is provided on the inner wall of the lens barrel 11, the pressure ring 13 and the connecting part 113 are detachably connected, and at least one connecting part 113 is adjacent to and alternately spaced from at least one lens mounting position 111.

[0094] Specifically, the connecting part 113 can be an internal thread structure, and the pressure ring 13 is provided with an external thread, and the pressure ring 13 is threadedly connected to the connecting part 113.

[0095] In this embodiment, the connecting part 113 and the lens mounting position 111 are arranged alternately and adjacently, which can make each pressure ring 13 press tightly with the corresponding optical lens 12, further improving the stability of the optical lens 12 in the lens mounting position 111, and further improving the stability and accuracy of the optical path assembly 1 in adjusting the light emitted by the light source 22.

[0096] In other embodiments, the optical path assembly 1 also includes a spacer ring. At least one mating section is provided on the inner wall of the lens barrel 11. The outer ring of the spacer ring is smoothly mated with the mating section. At least one mating section is adjacent to at least one lens mounting position 111 and is arranged alternately. The spacer ring is disposed between two adjacent optical lenses 12. One end face of the spacer ring abuts against the outer optical lens 12 that is pressed by the pressure ring, and the other end face of the spacer ring abuts against another optical lens 12, thereby realizing the stacking and fixing of multiple optical lenses 12.

[0097] In some embodiments, such as Figure 1-3 As shown, the multi-light source adjustment device also includes an interface connector 4 for fixing and installing external components; the interface connector 4 is fixedly installed at the end of the lens barrel 11.

[0098] Specifically, the interface connector 4 can be a flange connector, which can be bolted to the end of the lens barrel 11.

[0099] Specifically, the interface connector 4 may be provided with multiple connection structures, and be fixedly connected to external components through the connection structures.

[0100] In some embodiments, the interface connector 4 is provided with four threaded connection holes, and external components are connected to the interface connector 4 by bolts, thereby improving the assembly efficiency of external components and adjustment devices, and also making it easier for operators to replace external components according to specific needs.

[0101] In some embodiments, the interface connector 4 and the lens barrel 11 are integrally formed, which ensures the connection stability between the interface connector 4 and the lens barrel 11.

[0102] In some embodiments, such as Figure 1-3 As shown, the multi-light source adjustment device also includes a heat dissipation device 5; the heat dissipation device 5 is fixedly connected to the core adjustment assembly 3 and is used to dissipate heat for the light source carrier 21.

[0103] Specifically, the heat dissipation device 5 can be an LED heat sink, which can be fixed on the first adjusting member 31. The light source carrier 21 and the LED heat sink are fixedly arranged on both sides of the first adjusting member 31. The first adjusting member 31 is made of a thermally conductive material to facilitate the transfer of heat generated by the light source assembly 2 to the LED heat sink.

[0104] Specifically, the first adjusting member 31 is provided with a fixing threaded hole, and the LED heat sink is provided with a connecting hole that mates with the fixing threaded hole. The first adjusting member 31 and the LED heat sink can be fixedly connected by bolts.

[0105] In this embodiment, a heat dissipation device 5 is provided on the first adjusting member 31, and the light source carrier 21 and the LED heat sink are fixedly arranged on both sides of the first adjusting member 31. The heat dissipation device 5 can dissipate heat for the light source carrier 21, thereby improving the performance and service life of the light source carrier 21.

[0106] In other embodiments, the heat dissipation device 5 may be welded onto the first adjusting member 31, and the heat dissipation device 5 and the first adjusting member 31 may be an integral part.

[0107] In some embodiments, the portion of the optical path assembly 1 through which the light path passes is coated with a light-absorbing layer or a light-masking layer.

[0108] Specifically, a light-absorbing layer can be applied to the parts through which the light path passes, such as the inner cavity of the lens barrel 11 and the inner wall of the pressure ring, to prevent multiple specular reflections of light and reduce the interference of stray light on the working light.

[0109] In other embodiments, an matting layer with a threaded stepped structure may be provided on the inner cavity of the lens barrel 11 and / or the inner wall of the pressure ring.

[0110] In this embodiment, by providing a light-absorbing layer or a light-extending layer along the optical path through which the light passes, the number of light reflections can be effectively reduced, thereby reducing the interference of stray light on the working light.

[0111] This application also provides an optical device, which includes the multi-light source adjustment device described in the above embodiments.

[0112] Specifically, the optical equipment may include a lithography mechanism body, which is fixedly connected to a multi-source adjustment device.

[0113] The multi-light source adjustment device provided in this application has at least the following beneficial effects:

[0114] 1. In this embodiment, at least two light sources 22 are distributed on the light source carrier 21. The light source carrier 21 is fixed on the adjusting assembly 3. One end of the adjusting assembly 3 is fixed on the lens barrel 11. The adjusting assembly 3 can drive the light source carrier 21 to move relative to the lens barrel 11, thereby adjusting the light emission center of any one of the at least two light sources 22 to be aligned with the optical axis of the lens barrel 11. This allows the center of the light emission surface of any one of the light sources 22 to be adjusted to be coaxial with the optical axis of the lens barrel 11. This improves the optical efficiency of the light output of the required light source without replacing the high-power light source. Moreover, the multi-light source adjustment device has a simple and compact structure and is easy to operate.

[0115] 2. In this embodiment, by arranging at least two colors of light sources 22 on the light source carrier 21, the light source carrier 21 can be moved relative to the lens barrel 11 by the core adjustment assembly 3, thereby adjusting the center of the light-emitting surface of the light source 22 of different colors to be aligned with the optical axis of the lens barrel 11, and at the same time making the emitted light spot projected by the light source 22 cover the area to be illuminated, ensuring that the light spot is projected to the correct position, thereby improving the optical efficiency of the light output of the light source 22 of the required color.

[0116] 3. In this embodiment, the lens barrel 11 can not only fix and protect the optical lens 12, but also the guide shaft section 112 at one end of the lens barrel 11, in cooperation with the third adjusting member 33, can drive the light source carrier 21 on the first adjusting member 31 to move and rotate relative to the lens barrel 11 in a third direction, so as to adjust the relative distance and angle between the light source carrier 21 and the lens barrel 11, thereby improving the uniformity of the area to be illuminated, and at the same time ensuring that the emitted light spot projected by the light source 22 can completely cover the area to be illuminated, ensuring that the light spot is projected to the correct position, thereby improving the optical efficiency of the output light of any desired light source 22.

[0117] 4. The first adjusting member 31 can not only fix and support the light source assembly 2, but also drive the light source 22 to adjust left and right in the first direction.

[0118] 5. The second adjusting member 32 not only adjusts the light source 22 to move up and down along the second direction, but also serves as a reference plate when the first adjusting member 31 is adjusted. That is, the first adjusting member 31, together with the light source 22, adjusts left and right relative to the second adjusting member 32 along the first direction.

[0119] 6. The third adjustment member 33 not only connects the second adjustment member 32 and the optical path assembly 1, but also adjusts the light source 22 to move back and forth and rotate along the third direction. At the same time, it also serves as a reference plate when the second adjustment member 32 is adjusted. That is, the second adjustment member 32 drives the first adjustment member 31 to work together with the light source 22 to adjust up and down relative to the third adjustment member 33 along the second direction.

[0120] 7. In this embodiment, an adjustable clamping member 331 is provided on the third adjusting member 33. The adjustable clamping member 331 is sleeved on the guide shaft section 112 of the lens barrel 11, preventing the adjustable clamping member 331 from moving in the first and second directions, so that it only moves along the optical axis direction, i.e., the third direction, and rotates around the optical axis direction. By adjusting the tightness of the adjustable clamping member 331 and the lens barrel 11, not only can the distance between the third adjusting member 33 and the lens barrel 11 be adjusted, thereby coordinating and adjusting the relative distance between the light source carrier 21 and the lens barrel 11, thus improving the uniformity of the emitted light spot projected by the light source 22 onto the area to be illuminated; moreover, the rotation of the third adjusting member 33 relative to the lens barrel 11 can be adjusted, thereby coordinating and adjusting the rotation of the light source carrier 21 relative to the lens barrel 11, thereby adjusting the emitted light spot of any light source 22 on the first adjusting member 31 to coincide with the area to be illuminated.

[0121] 8. In this embodiment, by providing a gap 336 between the adjustable clamp 331 and the connecting body 332, the adjustable clamp 331 can have adjustable elasticity relative to the rigid connecting body 332. After the adjustable connecting part 3311 is locked, the adjustable clamp 331 is connected to the guide shaft section 112, and its inner diameter is slightly smaller than the inner diameter of the guide shaft mating part 335, thereby achieving reliable fixed connection between the adjustable clamp 331 and the lens barrel 11.

[0122] 9. In this embodiment, by providing a first limiting groove 312 on the first adjusting member 31 and a first limiting groove 312 that slides with the first guide shaft 311 on the second adjusting member 32, the light source 22 on the first adjusting member 31 can be driven to move along the first limiting groove 312; by providing a second limiting groove 322 on the second adjusting member 32 and a second limiting groove 322 and a second guide shaft 321 that slides with the second limiting groove 322 on the third adjusting member 33, the second adjusting member 32 can be driven to move along the second limiting groove 322; through the cooperation of the limiting groove and the guide shaft, the adjusting core assembly 3 can be provided with motion guidance in the first direction and the second direction, thereby adjusting the light emission center of any light source 22 on the first adjusting member 31 to move coaxial with the optical axis of the optical path assembly 1.

[0123] 10. In this embodiment, by placing the guide shaft section 112 within at least a portion of the guide shaft mating part 335, when adjusting the relative positional relationship between the third adjusting member 33 and the lens barrel 11, the adjustable clamping member 331 is loosened. Since the guide shaft section 112 is placed within at least a portion of the guide shaft mating part 335, the guide shaft mating part 335 can bear part of the weight of the lens barrel 11. This avoids the problem that the adjustable clamping member 331 may experience reduced reliability or even damage to the connection with the connecting body 332 due to the concentrated force on the lens barrel 11 caused by the existence of the gap 336, thereby further improving the stability of the connection between the lens barrel 11 and the third adjusting member 33.

[0125] Please refer to Figure 1-9 This embodiment provides a multi-light source adjustment device, including an optical path assembly 1, a light source assembly 2, and a core-aligning assembly 3. The optical path assembly 1 is disposed on the outgoing light path of the light source assembly 2. The optical path assembly 1 includes a lens barrel 11, and the inner cavity of the lens barrel 11 accommodates at least one optical lens 12. The light source assembly 2 includes at least two light sources 22 and a light source carrier 21, and the at least two light sources 22 are distributed on the light source carrier 21. The core-aligning assembly 3 is fixedly connected to the light source carrier 21, and one end of the core-aligning assembly 3 is connected to the lens barrel 11. The core-aligning assembly 3 can drive the light source carrier 21 to move relative to the lens barrel 11, thereby adjusting the light emission center of any one of the at least two light sources 22 to be aligned with the optical axis of the lens barrel 11.

[0126] like Figure 4 As shown, the core-adjusting assembly 3 includes an X-axis adjustment component, a Y-axis adjustment component, and a Z-axis adjustment component. One end face of the X-axis adjustment component is provided with a mounting threaded hole. The light source carrier 21 is fixed on the X-axis adjustment component by threaded connection between the clamping screw and the mounting threaded hole. The X-axis adjustment component is also provided with a clearance structure 313. The power supply wire of the external power supply can be electrically connected to the light source carrier 21 through the clearance structure 313. An LED heat sink is fixedly provided on the other end face of the X-axis adjustment component for heat dissipation of the light source carrier 21.

[0129] A fastening hose is fixedly provided on the side of the Z-axis adjustment component that mates with the lens barrel 11. The fastening hose is sleeved on the lens barrel 11. By adjusting the tightness of the fastening hose and the lens barrel 11, the Z-axis adjustment component can be rotated relative to the lens barrel 11. The Z-axis adjustment component can also be adjusted to slide along the axial direction of the guide shaft section 112 of the lens barrel 11, thereby adjusting the relative distance between the light source carrier 21 and the lens barrel 11.

[0130] like Figure 6 As shown, two lens mounting positions 111 are provided at intervals in the inner cavity of the lens barrel 11. An internal thread connection structure is provided between the two lens mounting positions 111. The optical lens 12 is housed in the corresponding lens mounting position 111. The pressure ring 13 is engaged with the internal thread connection structure to press the pressure ring 13 against the optical lens 12, thereby pressing the optical lens 12.

[0131] The inner cavity of the lens barrel 11 and the pressure ring are coated with a light-absorbing layer, which can effectively reduce the number of light reflections and reduce the interference of stray light on the working light.

[0132] A flange connector is integrally formed at the end of the lens barrel 11. The flange connector has threaded mounting holes, which facilitates the connection of external components to the flange connector, thereby improving the assembly efficiency of external components and adjustment devices. It also makes it easier for operators to replace external components according to specific needs.

[0133] This embodiment also provides an assembly process for a multi-light source adjustment device, as detailed below:

[0134] S1, the optical lens 12 is installed in the lens mounting position 111 inside the inner cavity of the lens barrel 11, and then the optical lens 12 is pressed and fixed in the lens mounting position 111 by the pressure ring 13.

[0135] S2, the light source carrier 12 with at least two light sources 22 is fixedly installed on the X-axis direction adjustment component, and the LED heat sink is fixedly connected to the other end face of the X-axis direction adjustment component.

[0136] S3, the X-axis adjustment component and the Y-axis adjustment component are fixedly connected by bolts, and the first limiting groove 312 on the X-axis adjustment component cooperates with the first guide shaft 311 on the Y-axis adjustment component.

[0138] S5, the fastening hose clamp on the Z-axis direction adjusting component is fitted onto the guide shaft section 112 of the lens barrel 11, and the Z-axis direction adjusting component is fixedly connected to the lens barrel 11 by adjusting the tightness of the fastening hose clamp and the guide shaft section 112.

[0139] This embodiment also provides an adjustment process for a multi-light source adjustment device, as detailed below:

[0140] First, loosen the bolts connecting the X-axis and Y-axis adjusting components, move the X-axis adjusting component to make the first guide shaft 311 slide along the first limiting groove 312; loosen the bolts connecting the Z-axis and Y-axis adjusting components, move the Y-axis adjusting component to make the second guide shaft 321 slide along the second limiting groove 322, thereby moving the light emission center of the required light source 22 on the light source carrier 12 to be aligned with the optical axis of the lens barrel 11; tighten the connecting bolts of the X-axis and Y-axis adjusting components, as well as the connecting bolts of the Z-axis and Y-axis adjusting components.

[0141] Then, loosen the connection between the fastening hose on the Z-axis adjustment component and the guide shaft section 112 of the lens barrel 11, so that the Z-axis adjustment component rotates relative to the lens barrel 11, and can be adjusted to slide along the axial direction of the guide shaft section 112 of the lens barrel 11, thereby adjusting the relative distance between the light source carrier 21 and the lens barrel 11, so that the emitted light spot emitted by the light source 22 covers the area to be illuminated, so that the position and illumination angle of the light spot emitted by the light source 22 projected onto the area to be illuminated meet the requirements.

[0142] Finally, tighten the hose clamp.
