Description
Technical Field
[0001] The present application belongs to the technical field of laser projection and laser lighting, and specifically relates to a three-primary-color laser light source system. Background Art
[0002] With the gradual development of optical projection and lighting technology, the projection equipment on the market mainly includes lamp projection and laser projection. The main difference between the two projection equipment lies in the output light source. The lamp projection equipment uses high-pressure mercury lamp as the light source, while the laser projection equipment uses laser as the light source. As the laser light source has a longer life and better color reproduction than the lamp light source, the laser projection equipment using laser light source has gradually replaced the traditional lamp projection equipment.
[0003] At present, the laser light sources in the laser projection equipment on the market are divided into blue laser excitation phosphor synthesized white light and red laser, green laser, blue laser three-color synthesized white light. This technology is generally equipped with red, green and blue lasers, and a reflector array for concentrating the light source emitted by the three-primary color laser, so as to realize the output of the three-primary color laser light source after concentration for corresponding projection applications. Commonly used reflector light source arrays in the prior art include step mirror light source arrays and X-mirror light source arrays.
[0004] The step mirror light source array is a step-shaped array in which multiple reflective lenses are set at a gradually increasing distance from the laser, and the reflected output light beams do not overlap, so as to reflect the light source projected by the three-primary color laser set on one side of the reflective lens one by one to a unified designated direction for output. The use of the step mirror light source array requires a large space, thereby increasing the size of the equipment, and the light path output through the step mirror light source array is scattered and has low concentration, resulting in a significantly low brightness of the output laser light source.
[0005] The X-mirror light source array integrates multiple reflective lenses into an X-shaped X-mirror structure, and arranges the three-primary color lasers around the periphery of the X-mirror structure, and the laser light source input from the periphery is uniformly reflected to the specified direction for output through the X-mirror structure. Although the use of the X-mirror light source array can effectively reduce the occupied space and the size of the equipment, the light path for reflection output through the X-mirror structure is relatively complex, resulting in low integration; moreover, the lasers can only be arranged around the periphery of the X-mirror structure, thus limiting the volume and number of lasers to be set, resulting in low scalability and insufficient brightness of the output light source.
[0006] Therefore, the structure of the three-primary-color laser light source system in the prior art needs to be improved, which is a difficult research problem for laser projection manufacturers. Summary of the invention
[0007] The purpose of the embodiments of the present application is to provide a three-primary-color laser light source system, to improve the projection method of the laser light source, to make the lens array more concise and scalable, to save space, and to effectively improve the coaxiality and integration of the optical path, thereby enhancing the output light source brightness.
[0008] To achieve the above-mentioned purpose, the technical solution adopted in the present application is: to provide a three-primary-color laser light source system, a mirror array component, a light source component, an output component, and a light source container for respectively installing the mirror array component, the light source component, and the output component;
[0009] The mirror array assembly comprises a plurality of mirror frames and a plurality of fixing platforms for mounting the mirror frames, the mirror frames having a light-transmitting hole, and the mirror frames are provided with a bandpass light-combining mirror arranged adjacent to the light-transmitting hole; the optical axes of the plurality of fixing platforms are coaxially aligned in the light source output direction of the three-primary-color laser light source system, and are arranged in the light source container in an orderly and spaced manner; the bandpass light-combining mirrors and the light-transmitting holes on each of the mirror frames are oriented in the same direction and are coaxially aligned;
[0010] The light source assembly comprises a plurality of laser modules for projecting light beams onto the mirror frame, the plurality of laser modules are arranged around the circumference of the mirror array assembly, and one or more of the plurality of laser modules are arranged coaxially with the optical axis of the mirror frame in the light source output direction of the three-primary-color laser light source system;
[0011] The output assembly includes a directional platform and a deflection reflector for deflecting the light beam output from the mirror frame. The deflection reflector is arranged on the directional platform and reflects the light beam for output.
[0012] The beneficial effect of the three-primary-color laser light source system provided by the present application is that: compared with the prior art, the lens light source array used in the three-primary-color laser light source system of the present application is composed of a frame provided with a bandpass light-combining mirror and a light-transmitting hole, the optical axis of which is coaxially aligned in the output direction of the light beam, and a side-by-side mirror light source array arranged in an orderly and spaced manner, so that the frames are coaxially aligned, and laser modules are arranged in the circumferential direction of the side-by-side mirror light source array, and the laser module can be preferably arranged on the side where the light beam can be projected onto the bandpass light-combining mirror, and at least one laser module is coaxially arranged with the frame of the side-by-side mirror light source array in the light source output direction of the present three-primary-color laser light source system. The output light source of each laser module is allowed to project the light source onto the side-by-side mirror light source array from one end and the side, respectively, and the bandpass light-combining mirror and the light-transmitting hole on the side-by-side mirror light source array are used to realize light transmission and selective reflection and light combination, and then the light sources output from each laser module are uniformly converged and output, effectively improving the coaxiality and integration of the optical path.
[0013] Among them, a fixing platform for installing the mirror frame is provided in the light source container. The fixing platform can be used to pre-position the reflection angle, so that the mirror frame equipped with the pass-through light-combining mirror can be directly installed on the fixing platform, and the lens installation operation can be completed quickly without fine-tuning the reflection angle. The reflection output application of the light source can be carried out, which effectively improves the installation and debugging efficiency.
[0014] Compared with the stepped mirror light source array in the prior art, the side-by-side mirror light source array of the present application does not require adjustment of the position of each lens, occupies less space, and each frame with lenses installed is coaxial and arranged side by side in a specified direction. It has a simple structure, is neat and beautiful, and effectively improves space utilization.
[0015] Compared with the X-ray mirror light source array of the prior art, the reflective light path of the side-by-side mirror light source array of the present application is simpler and more integrated. The array of mirrors is arranged side by side, so that the periphery of the array can form an expansion space for increasing the laser module, effectively improving the scalability of the array, and thus enhancing the brightness of the output light source.
[0016] Compared with the existing technology that also uses a side-by-side mirror light source array, the side-by-side mirror light source array of the present application utilizes the cooperation of the bandpass light combining mirrors and light-transmitting holes provided on each mirror frame. While ensuring the coaxiality of the optical path, the output light source can be expanded by adding a corresponding number of mirror frames and laser modules with bandpass light combining mirrors and light-transmitting holes, which can effectively improve the expansion performance of the entire reflector light source array.
[0017] The structure of the light source container is improved, and the light source container is provided with a first position opposite to the turning reflector, a second position located at the side of the mirror array assembly and adjacent to the first position, and a third position located at the side of the mirror array assembly and adjacent to the output assembly and the second position. The first position is provided with a blue laser module that outputs a blue light source, the second position is provided with a green laser module that outputs a green light source, and the third position is provided with a red laser module that outputs a red light source. On the one hand, in order to match the different powers of the lasers of different colors set on the laser module, the common blue laser has a higher output power than the green and red lasers. Therefore, in view of the advantage of the larger expandable space on the side of the side-by-side lens array adopted in this application, a blue laser module is provided at one end of the lens array, and a green laser module and a red laser module are sequentially provided on the same side of the lens array, so as to provide a space for the green laser module and the red laser module to be expandable, thereby improving the output light source brightness of the entire light source system. On the other hand, since the red laser light source emitted by the red laser module has a larger spot size than the blue and green laser light sources, it is necessary to perform light beam compression at a short distance during optical transmission to ensure the coaxiality of the optical path. Therefore, a red laser module is preferably arranged at a third position adjacent to the output component on the side of the lens array, so that the light source projected from the red laser module to the lens array can perform light beam compression at a short distance, and then the layout positions of the laser modules of each color system are preferably set from a physical structure perspective, effectively improving the coaxiality and integration of the optical path.

For the expansion setting of the green laser module and the red laser module, the number of semiconductor lasers of the corresponding color system can be selectively increased on the green laser module and the red laser module, and in order to cooperate with the side-by-side mirror array used in this application, the semiconductor lasers on the laser module are preferably arranged side by side, and the output light source is projected onto the bandpass light-combining mirror of the mirror frame at the corresponding position, so as to focus the expanded laser light source into the light path of the lens array, thereby ensuring the coaxiality of the output light path.

In view of the specifications and layout of the side-by-side mirror array and the above-mentioned laser modules adopted in this application, the mirror array assembly of this application includes at least four mirror frames, and the first mirror frame, the second mirror frame, the third mirror frame, and the fourth mirror frame are sequentially arranged according to the setting positions of the laser modules of the above-mentioned blue, green, and red color systems. The bandpass light combiner installed on each mirror frame is accurately aligned with the laser modules of each color system, so that the corresponding laser light source projected onto the bandpass light combiner is gathered and coaxially output in the specified direction for application.
[0020] Optionally, the first mirror frame is provided with a first light-transmitting hole for transmitting a blue light source and a first band-pass light-combining mirror that reflects a green light source; the second mirror frame is provided with a second light-transmitting hole for transmitting a green light source and a second band-pass light-combining mirror that transmits the blue light source and reflects the green light source; the third mirror frame is provided with a third light-transmitting hole for transmitting a blue and green light source and a third band-pass light-combining mirror that transmits the green light source and reflects the red light source; the fourth mirror frame is provided with a fourth light-transmitting hole for transmitting a red and green light source and a fourth band-pass light-combining mirror that transmits the blue and green light sources and reflects the red light source. The first light-transmitting hole and the first bandpass light-combining mirror on the first frame can be used to transmit the blue light source of the blue laser module in the output direction and reflect the green light source of the first green semiconductor laser on the side green laser module at the same time; the second light-transmitting hole and the second bandpass light-combining mirror on the second frame can be used to transmit the blue light source of the blue laser module in the output direction and reflect the green light source of the second green semiconductor laser on the side green laser module at the same time; the third light-transmitting hole and the third bandpass light-combining mirror on the third frame can be used to transmit the blue light source of the blue laser module and the reflected green light source in the output direction and reflect the red light source of the first red semiconductor laser on the side red laser module at the same time; the fourth light-transmitting hole and the fourth bandpass light-combining mirror on the fourth frame can be used to transmit the blue light source of the blue laser module and the reflected green and red light sources in the output direction and reflect the red light source of the second red semiconductor laser on the side red laser module at the same time. The output light sources of the laser modules of each color system are gathered in the lens array and uniformly output in the specified direction for application, effectively improving the coaxiality and integration of the optical path.

On the one hand, in order to form a structure with a lens and a light-transmitting hole on the frame, a light-passing port is provided on the frame, and at least two mounting grooves for mounting the lens are provided on the light-passing port, so that the bandpass light-combining mirror can be selectively installed in the corresponding mounting groove according to the set position, and the light-passing port where the mounting groove without the lens is installed can form a light-transmitting hole, so that the frame is provided with adjacent light-transmitting holes and lenses for reflecting the output light source of the laser module at the corresponding position. Among them, the bandpass light-combining mirror installed on the frame can simultaneously play the role of filtering and reflecting the specified color beam, and is combined with the light-transmitting hole to be applied to the side-by-side mirror light source array of the present application, effectively improving the coaxiality and integration of the optical path. On the other hand, the mounting groove on the frame and the fixing clamp are provided with corresponding positioning notches, fixing pressure plates and first connecting ears and other fixing structures to strengthen the positioning of the reflection angle of the lens, and fasteners such as fixing screws are added through the mutual alignment of the first connecting hole and the fixing hole, thereby effectively improving the fixing effect.

[0025] In the lens array, the fixed state of the lens is particularly important. A slight change in the mirror angle of the lens will affect the integration of the reflected light beam and the coaxiality of the entire optical path. To this end, a plurality of fixed columns are arranged on the side wall of the light source container to be connected to the fixed platform at the corresponding position, a first mounting hole and a first insert are arranged on the fixed column, and a second mounting hole and a second insert are arranged on the fixed platform.

The fixed column and the fixed platform are respectively fixed at multiple angles in the vertical and horizontal directions of the frame, thereby locking the orientation angles of the lens and the light-transmitting hole installed on the frame, effectively ensuring the coaxiality and integration of the output optical path in the lens array.
[0026] In addition, in order to accurately gather the light source projected from the side of the lens array into the output light path of the lens array, each fixed platform is tilted toward the laser module at the corresponding position on the side of the lens array, and is provided with a bandpass light-combining mirror that can be installed on the frame installed on each fixed platform to reflect the light beam projected by the laser module at the second position or the third position to the output direction at a reflection angle. Among them, the reflection angle can be preferably set to 90 degrees, so as to uniformly gather the projected light source of the laser module at the second position or the third position on the side into the output light path of the lens array, effectively simplifying the direction of the light path and ensuring the coaxiality and integration of the light path. Since the tilt setting of the fixed platform pre-sets the reflection angle, the frame installed with the bandpass light-combining mirror can be directly installed on the fixed platform for automatic alignment without the need for angle adjustment, so that the lens can be quickly installed or replaced, effectively improving the installation and debugging efficiency.

The plurality of laser modules 5 are arranged around the circumference of the mirror array assembly 100, and one or more of the plurality of laser modules 5 are coaxially aligned with the optical axis of the frame 1 in the light source output direction of the three-primary-color laser light source system. In this embodiment, it is preferred that at least one laser module 5 is coaxially arranged with the frame 1.
[0069] The output assembly 300 includes an orientation platform 61 and a deflection reflector 62 for deflecting the light beam output from the mirror frame 1 . The deflection reflector 62 is disposed on the orientation platform 61 and reflects the light beam for output.
[0070] Compared with the prior art, the three-primary-color laser light source system of the present application is innovatively designed based on the three-primary-color laser technology of synthesizing white light based on red laser, green laser and blue laser, wherein the three-primary-color red laser, green laser and blue laser can be composed of a single wavelength or multiple wavelengths respectively. The lens light source array used in the three-primary-color laser light source system of the present application is composed of a frame 1 provided with a bandpass light combiner 3 and a light-transmitting hole 4, which is coaxially aligned with the optical axis in the output direction of the light beam, and an array of side-by-side mirror light sources arranged in an orderly and spaced manner, so that the frames 1 are coaxially aligned with each other, and laser modules 5 are arranged in the circumferential direction of the side-by-side mirror light source array, and the laser module 5 can be preferably arranged on the side where the light beam can be projected onto the bandpass light combiner 3, and at least one laser module 5 is coaxially arranged with the frame 1 of the side-by-side mirror light source array in the light source output direction of the present three-primary-color laser light source system. The output light sources of each laser module 5 are projected onto the side-by-side mirror light source array from one end and the side of the side-by-side mirror light source array, respectively, and the bandpass light combining mirror 3 and the light transmission hole 4 on the side-by-side mirror light source array are used to realize light transmission and selective reflection and light combining, thereby uniformly converging and outputting the light sources output from each laser module 5, effectively improving the coaxiality and integration of the optical path.
[0071] Among them, a fixing platform 2 for installing the mirror frame 1 is provided in the light source container 400. The fixing platform 2 can be used to pre-position the reflection angle, so that the mirror frame 1 installed with the pass-through light-combining mirror 3 can be directly installed on the fixing platform 2, and the lens installation operation can be completed quickly without fine-tuning the reflection angle. The reflection output application of the light source can be carried out, which effectively improves the installation and debugging efficiency.
[0072] Compared with the stepped mirror light source array in the prior art, the side-by-side mirror light source array of the present application does not require adjustment of the position of each lens, occupies less space, and each frame 1 with lenses installed is coaxially arranged side by side in a specified direction, has a simple structure, is neat and beautiful, and effectively improves space utilization.
[0073] Compared with the X-ray mirror light source array in the prior art, the side-by-side mirror light source array of the present application has a simpler reflection light path and a higher degree of integration. The array of mirrors is arranged side by side, so that the periphery of the array forms an expansion space for increasing the laser module 5, effectively improving the scalability of the array, thereby enhancing the brightness of the output light source.
[0074] Compared with the existing technology that also uses a side-by-side mirror light source array, the side-by-side mirror light source array of the present application utilizes the cooperation of the bandpass light combining mirrors 3 and the light-transmitting holes 4 provided on each mirror frame 1. While ensuring the coaxiality of the optical path, the output light source can be expanded by adding a corresponding number of mirror frames 1 with bandpass light combining mirrors 3 and light-transmitting holes 4 and laser modules 5, which can effectively improve the expansion performance of the entire reflector light source array.
[0075] In another embodiment of the present application, the structure of the light source container 400 is optimized. Figure 2 The light source container 400 is provided with a first position opposite to the turning reflector, a second position located at the side of the mirror array assembly 100 and adjacent to the first position, and a third position located at the side of the mirror array assembly 100 and adjacent to the output assembly 300 and the second position. The first position is provided with a blue laser module 51 for outputting a blue light source, the second position is provided with a green laser module 52 for outputting a green light source, and the third position is provided with a red laser module 53 for outputting a red light source. On one hand, in order to match the different powers of the lasers of different colors set on the laser module 5, the output power of the common blue laser is higher than that of the green and red lasers. Therefore, in view of the advantage of the large expandable space on the side of the side mirror array adopted in the present application, a blue laser module 51 is provided at one end of the mirror array, and a green laser module 52 and a red laser module 53 are sequentially provided on the side of the mirror array, so as to provide a space for the green laser module 52 and the red laser module 53 to be expandable, thereby improving the output light source brightness of the entire light source system. On the other hand, since the red laser light source emitted by the red laser module 53 has a larger spot size than the blue and green laser light sources, it is necessary to perform light beam compression at a short distance during light path transmission to ensure the coaxiality of the light path. Therefore, the red laser module 53 is preferably arranged at a third position adjacent to the output component 300 on the side of the lens array, so that the light source projected from the red laser module 53 to the lens array can perform light beam compression at a short distance, and then the layout positions of the laser modules 5 of each color system are preferably set from a physical structure perspective, thereby effectively improving the coaxiality and integration of the light path.
[0076] In another embodiment of the present application, please refer to Figure 3 , the green laser module 52 is provided with at least two green semiconductor lasers arranged side by side, and at least one of the green semiconductor lasers outputs a green light source to the bandpass light combiner 3 on the mirror frame 1 at the corresponding position; the red laser module 53 is provided with at least two red semiconductor lasers arranged side by side, and at least one of the red semiconductor lasers outputs a red light source to the bandpass light combiner 3 on the mirror frame 1 at the corresponding position. To this end, for the expansion setting of the green laser module 52 and the red laser module 53, the number of semiconductor lasers of the corresponding color system can be selectively increased on the green laser module 52 and the red laser module 53, and in order to cooperate with the side-by-side mirror array used in this application, the semiconductor lasers on the laser module 5 are preferably arranged side by side, and the output light source is projected onto the bandpass light combiner 3 of the mirror frame 1 at the corresponding position, so as to focus the expanded laser light source into the light path of the lens array, thereby ensuring the coaxiality of the output light path.
[0077] In another embodiment of the present application, please refer to the specification and layout of the side-by-side mirror array and the laser module 5 used in the present application. Figure 2 and Figure 3 The mirror array assembly 100 is provided with at least four mirror frames 1, and the four mirror frames 1 include a first mirror frame 101 for reflecting the green light source output by the green laser module 52, a second mirror frame 102 disposed adjacent to the first mirror frame 101 and for reflecting the green light source output by the green laser module 52, a third mirror frame 103 disposed adjacent to the second mirror frame 102 and for reflecting the red light source output by the red laser module 53, and a fourth mirror frame 104 disposed adjacent to the third mirror frame 103 and for reflecting the red light source output by the red laser module 53.

[0080] The third mirror frame 103 is provided with a third light-transmitting hole 43 for transmitting the blue and green light sources and a third band-pass light-combining mirror 33 for transmitting the green light source and reflecting the red light source. The third light-transmitting hole 43 and the third band-pass light-combining mirror 33 on the third mirror frame 103 can be used to transmit the blue light source of the blue laser module 51 and the reflected green light source in the output direction, and at the same time reflect the red light source of the first red semiconductor laser on the side red laser module 53.
[0081] The fourth mirror frame 104 is provided with a fourth light-transmitting hole 44 for transmitting the red and green light sources, and a fourth band-pass light-combining mirror 34 for transmitting the blue and green light sources and reflecting the red light source. The fourth light-transmitting hole 44 and the fourth band-pass light-combining mirror 34 on the fourth mirror frame 104 can be used to transmit the blue light source of the blue laser module 51 and the reflected green and red light sources in the output direction, and at the same time reflect the red light source of the second red semiconductor laser on the side red laser module 53.
[0082] By providing the bandpass light combiner 3 and the light-transmitting hole 4 at corresponding positions on the first frame 101, the second frame 102, the third frame 103 and the fourth frame 104, the output light sources of the laser modules 5 of each color system are gathered in the lens array and output in a designated direction, thereby effectively improving the coaxiality and integration of the optical path.
[0083] In another embodiment of the present application, the structure of the frame 1 is optimized. Figure 4 and Figure 5 The frame 1 is provided with a light passing port located in the middle of the frame 1 and a surrounding edge 11 arranged around the outer periphery of the light passing port, and the frame 1 is also provided with at least two mounting grooves 12 surrounded by the surrounding edge 11; the surrounding edge 11 is provided with a positioning notch 13, and the frame 1 is provided with a fixing hole 14 that matches the position of the positioning notch 13; the frame 1 is provided with a fixing clip 15 for fixing the band-pass light-combining mirror 3, and the fixing clip includes a first connecting ear 16 and a fixing pressing plate 17, and the first connecting ear 16 is provided with a first connecting hole 161; the band-pass light-combining mirror 3 is selectively installed on at least one of the mounting grooves 12, and the light passing port where the remaining mounting grooves are located forms a light-transmitting hole 4; the first connecting ear 16 of the fixing clip 15 is mutually embedded with the positioning notch 13, so that the first connecting hole 161 and the fixing hole 14 are mutually aligned, and the fixing pressing plate 17 presses the edge of the band-pass light-combining mirror 3.
[0084] On the one hand, in order to form a structure with a lens and a light-transmitting hole 4 on the frame 1, a light-passing port is provided on the frame 1, and at least two mounting grooves 12 for mounting lenses are provided on the light-passing port, so that the bandpass light-combining mirror 3 can be selectively installed in the corresponding mounting groove 12 according to the set position, and the light-passing port where the mounting groove 12 without a lens is located can form a light-transmitting hole 4, so that the frame 1 is provided with a light-transmitting hole 4 and a lens for reflecting the output light source of the laser module 5 at the corresponding position adjacently. Among them, the bandpass light-combining mirror 3 installed on the frame 1 can simultaneously play the role of filtering and reflecting the specified color system light beam, and is combined with the light-transmitting hole 4 to be applied to the side-by-side mirror light source array of the present application, effectively improving the coaxiality and integration of the optical path. On the other hand, the mounting groove 12 on the frame 1 and the fixing clip 15 are provided with corresponding positioning notches 13, first connecting ears 16 and fixing pressure plates 17 and other fixing structures to strengthen the positioning of the reflection angle of the lens, and fasteners such as fixing screws are installed by aligning the first connecting hole 161 and the fixing hole 14, thereby effectively improving the fixing effect.
[0085] In the lens array, the fixed state of the lens is particularly important. A slight change in the mirror angle of the lens will affect the integration of the reflected light beam and the coaxiality of the entire optical path. For this reason, in another embodiment of the present application, the fixing structure of the frame 1 is optimized. Please refer to Figure 5 , Figure 6 and Figure 8 A fixing column 7 connected to the fixing platform 2 is provided on the side wall of the light source container 400, and a first mounting hole 71 and a first insertion strip 72 are provided on the fixing column 7. A hanging plate 18 is provided on the top of the mirror frame 1, and a through hole 181 is provided on the hanging plate 18 that matches the position of the first mounting hole 71 and the first insertion strip 72, so that corresponding alignment can be achieved or fasteners such as screws can be installed for fixation.
[0086] The fixing platform 2 is provided with a second mounting hole 21 and a second insertion strip 22, and the bottom of the frame 1 is provided with a connecting plate 19, and the connecting plate 19 is provided with a sleeve hole 191 that matches the position of the second mounting hole and the second insertion strip, so as to realize corresponding alignment and sleeve connection or add fasteners such as screws for fixing.
[0087] The fixing column 7 and the fixing platform 2 fix the frame 1 at multiple angles in the vertical and horizontal directions, thereby locking the orientation angles of the lenses and light-transmitting holes 4 mounted on the frame 1, effectively ensuring the coaxiality and integration of the output light path in the lens array.
[0088] On the basis of the above, the light source projected from the side of the lens array can be accurately focused into the output light path of the lens array. Please refer to Figure 7 and Figure 8The fixed platform 2 is a long strip support body, one end of the fixed platform 2 is connected to the fixed column 7, and the other end of the fixed platform 2 is inclined and extended toward the side wall of the light source container 400 opposite to the fixed column 7, and is provided with a band-pass light-combining mirror 3 that can be installed on the mirror frame 1 set on each fixed platform 2, and reflects the light beam projected by the laser module 5 at the second position or the third position to the reflection angle of the output direction. Among them, the reflection angle can be preferably set to 90 degrees, so as to uniformly gather the projected light source of the laser module 5 at the second position or the third position of the side on the output light path of the lens array, effectively simplifying the direction of the light path and ensuring the coaxiality and integration of the light path.
[0089] Since the fixed platform 2 is tilted to preset the reflection angle, the frame 1 equipped with the light-combining mirror 3 can be directly installed on the fixed platform 2 and automatically aligned without the need for angle adjustment, thereby enabling rapid installation or replacement of lenses and effectively improving installation and debugging efficiency.

The light source output by the lower semiconductor laser 502 on the laser module 5 is uniformly focused on the lens of the frame 1, effectively setting the projection direction of the expanded light beam to ensure the integration of the expanded light source, thereby improving the brightness of the laser light source.
