[0003] The current laser projection device can generally comprise a projection lens, a light engine system and a light source system. The light source system generally comprises a fluorescent wheel, a lens group and a laser. Here, the lens group can converge the laser beam provided by the laser to the fluorescent layer in the fluorescent wheel, so that the fluorescent layer emits fluorescent light under the excitation of the laser, and the fluorescent light emitted by the fluorescent wheel can be mixed with the laser to output the light engine system.

[0004] In order to ensure that the excitation efficiency of the fluorescent layer in the fluorescent wheel to the laser is high, it is necessary to ensure that the lens group can accurately converge the laser to the fluorescent layer. However, various devices in the current light source system are prone to assembly errors when assembled, and when the assembly error between the lens group and the fluorescent wheel is high, the excitation efficiency of the fluorescent layer in the fluorescent wheel to the laser will be affected, resulting in poor effect of the light beam output from the light source system to the light engine system. SUMMARY

In this way, the laser beam emitted by the laser can be focused on the fluorescent layer of the fluorescent wheel by the lens group in the lens assembly, so that the fluorescent layer can better emit fluorescent light under the excitation of the laser. After the lens assembly is assembled on the shell, if the operator finds that the assembly precision between the lens assembly and the fluorescent assembly is low, the operator can adjust the distance between the lens assembly and the fluorescent assembly by controlling the lens support in the lens assembly to move along the optical axis of the lens group in the mounting hole of the shell, so that the lens group in the lens assembly can better focus the laser beam on the fluorescent layer of the fluorescent wheel, effectively improving the excitation efficiency of the fluorescent layer in the fluorescent wheel to the laser, and thus the effect of the light beam output from the light source system to the light machine system is better.

[0031] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0032] Please refer to Figure 1 , Figure 1 is a structural schematic view of the light source system provided by the embodiment of the present application, which can include: a shell 100, a fluorescent assembly 200, a laser 300 and a lens assembly 400.

[0033] In order to make the internal structure of the light source system and the positional relationship between the shell 100, the fluorescent assembly 200, the laser 300 and the lens assembly 400 more clear, please refer to Figure 2 , Figure 2 is Figure 1An exploded view of the light source system is shown. The housing 100 in the light source system 000 can include: oppositely arranged first and second fixed frames 101 and 102, the first fixed frame 101 having a mounting hole D. Here, the housing 100 can further include a third fixed frame 103 between the first and second fixed frames 101 and 102, and the two ends of the third fixed frame 103 can be fixedly connected with the first and second fixed frames 101 and 102 respectively. In this way, the first and second fixed frames 101 and 102 can be connected as a whole through the third fixed frame 103. It should be noted that the first fixed frame 101, the second fixed frame 102 and the third fixed frame 103 in the housing 100 can be an integral structure. That is, the first fixed frame 101, the second fixed frame 102 and the third fixed frame 103 in the housing 100 can be formed at the same time through a one-time process (for example, an injection molding process).

[0034] The fluorescent assembly 200 in the light source system 000 can be connected with the side of the first fixed frame 101 in the housing 100 away from the second fixed frame 102. For example, the fluorescent assembly 200 can include: a support shell 201 connected with the side of the first fixed frame 101 away from the second fixed frame 102, and a fluorescent wheel 202 connected with the support shell 201. In this way, after the support shell 201 is connected with the side of the first fixed frame 101 away from the second fixed frame 102, the fluorescent assembly 200 can be installed as a whole on the side of the first fixed frame 101 away from the second fixed frame 102. It should be noted that the side of the fluorescent wheel 202 in the fluorescent assembly 200 close to the first fixed frame 101 has a fluorescent layer S.

[0035] The laser 300 in the light source system 000 can be connected with the side of the second fixed frame 102 away from the first fixed frame 101. After the laser 300 is connected with the side of the second fixed frame 102 away from the first fixed frame 101, it can be ensured that the laser beam emitted by the laser 300 can normally shoot towards the fluorescent wheel 202 in the fluorescent assembly 200. For example, as shown in Figure 2 the second fixed frame 102 can have a light passing hole 102a matched with the laser 300, and the light emitting surface of the laser 300 can face the light passing hole 102a. In this way, after the laser 300 is started, the laser beam emitted by the light emitting surface of the laser 300 can pass through the light passing hole 102a and then shoot towards the fluorescent layer S of the fluorescent wheel 202 in the fluorescent assembly 200.

[0036] The lens assembly 400 in the light source system 000 can include a lens holder 401 and a lens group 402 installed in the lens holder 401. The lens holder 401 is located in the mounting hole D in the first fixing frame 101, and the lens holder 401 can move along the optical axis of the lens group 402 in the mounting hole D. For example, the lens holder 401 in the lens assembly 400 is movably connected with the first fixing frame 101 in the mounting hole D, and the lens assembly 401 can move along the optical axis of the lens group 402 in the mounting hole D. When the lens assembly 400 moves along the optical axis of the lens group 402 in the mounting hole D, the distance between the lens assembly 400 and the fluorescent assembly 200 can be adjusted.

[0037] In the present application, as shown in Figure 3 Figure 3 is Figure 1 The light path diagram of the light source system is shown. The laser beam emitted by the laser 300 in the light source system 000 can be incident on the lens assembly 400, and the lens group 402 in the lens assembly 400 can converge the laser beam, and the converged laser beam can be incident on the fluorescent layer S of the fluorescent wheel 202. In this way, the laser beam emitted by the laser 300 can be focused on the fluorescent layer S of the fluorescent wheel 202 by the lens group 402 in the lens assembly 400, so that the fluorescent layer S can better emit fluorescent light under the excitation of the laser.

[0038] In the embodiment of the present application, after the fluorescent assembly 200 and the laser 300 are assembled on the first fixing frame 101 and the second fixing member 102 in the housing 100 respectively, and the lens assembly 400 is assembled in the mounting hole D of the first fixing frame 101, if the operator finds that the assembly precision between the lens assembly 400 and the fluorescent assembly 200 is low, the operator can adjust the distance between the lens assembly 400 and the fluorescent assembly 200 by controlling the lens holder 401 in the lens assembly 400 to move along the optical axis of the lens group 402 in the mounting hole D, so that the lens group 402 in the lens assembly 400 can better focus the laser beam on the fluorescent layer S of the fluorescent wheel 202, effectively improving the excitation efficiency of the fluorescent layer S in the fluorescent wheel 202 to the laser, and further making the light beam output from the light source system to the optical machine system better.

[0039] ​In summary, the application provides a light source system, comprising: a shell, a fluorescent assembly, a laser and a lens assembly. The laser beam emitted by the laser can be incident on the lens assembly, and the lens group in the lens assembly can converge the laser beam, and the converged laser beam can be incident on the fluorescent layer of the fluorescent wheel. In this way, the laser beam emitted by the laser can be focused on the fluorescent layer of the fluorescent wheel by the lens group in the lens assembly, so that the fluorescent layer can better emit fluorescent light under the excitation of the laser. After the lens assembly is assembled on the shell, if the operator finds that the assembly precision between the lens assembly and the fluorescent assembly is low, the operator can adjust the distance between the lens assembly and the fluorescent assembly by controlling the lens support in the lens assembly to move along the optical axis of the lens group in the mounting hole of the shell, so that the lens group in the lens assembly can better focus the laser beam on the fluorescent layer of the fluorescent wheel, effectively improving the excitation efficiency of the fluorescent layer in the fluorescent wheel to the laser, and thus the effect of the light beam output from the light source system to the light machine system is better.

[0040] It should be noted that the number of lens assemblies 400 in the light source system 000 provided by the embodiments of the application can be two, and the number of lasers 300 can also be two. The laser beams emitted by the two lasers 300 can be incident on the two lens assemblies 400 respectively. The number of fluorescent layers S in the fluorescent wheel 202 is also two. For example, as shown in Figure 4 , Figure 4 is a schematic view of a fluorescent wheel cooperating with two lenses provided by the embodiments of the application. The two fluorescent layers S in the fluorescent wheel 202 are annular, and the two fluorescent layers S can be nested. That is, one of the two fluorescent layers S has a smaller size, and the other fluorescent layer S has a larger size, and the smaller fluorescent layer S can be distributed in the area surrounded by the larger fluorescent layer S. Here, the two lens groups 402 in the two lens assemblies 400 respectively converge the laser beams emitted by the two lasers 300 and focus them on the two fluorescent layers S in the fluorescent wheel 220.

[0041] It should also be noted that, as shown in Figure 4 , in order to further improve the excitation efficiency of the fluorescent layer S to the laser, it is necessary to ensure that the central axis L0 of the fluorescent layer S intersects with the optical axis of the lens group 402 in the corresponding lens assembly 400.

[0042] In a possible implementation, the laser emitted by the laser 300 can be blue laser, and in the two fluorescent layers S of the fluorescent wheel 202, one fluorescent layer S can be a red fluorescent layer, and the other fluorescent layer S can be a green fluorescent layer. Among them, the red fluorescent layer can emit red fluorescence under the excitation of the laser, and the green fluorescent layer can emit green fluorescence under the excitation of the laser. In this way, the fluorescent wheel 202 can emit red fluorescence and green fluorescence respectively, and the red fluorescence and green fluorescence can be mixed with the blue laser again and output to the light engine system. In other possible implementations, the fluorescent layer S of the fluorescent wheel 202 can also be a fluorescent layer for emitting fluorescence of other colors under the excitation of the laser, and the embodiments of the present application do not limit this.

[0043] In the embodiments of the present application, please refer to Figure 5 and Figure 6 , Figure 5 is a schematic assembly view of a lens assembly and a first fixing frame provided by the embodiments of the present application, Figure 6 is a structural schematic view of a lens holder in a lens assembly provided by the embodiments of the present application. The lens holder 401 in the lens assembly 400 can have external threads, and the mounting hole D in the first fixing frame 101 can have internal threads matched with the external threads of the lens holder 401. In this way, the lens holder 401 can be mounted in the mounting hole D in the first fixing frame 101 in a threaded engagement manner. When the lens holder 401 rotates in the mounting hole D, the lens holder 401 moves along the optical axis of the lens group 402.

[0044] For example, please refer to Figure 7 , Figure 7 is Figure 6 the schematic view of the lens holder located on the other side. The end of the lens holder 401 close to the fluorescent assembly 200 has a tool embedding hole O, which can be clamped with a mounting tool. When assembling the lens assembly 400, the operator can clamp the lens assembly 400 as a whole by clamping the tool embedding hole O with the mounting tool, and then can control the lens holder 401 in the lens assembly 400 to be screwed into the mounting hole D. In this way, the lens assembly 400 can be installed in the mounting hole D. After the light source system 000 is assembled, if it is necessary to adjust the relative position between the lens group 402 and the fluorescent wheel 202, the operator can move the lens holder 401 along the optical axis of the lens group 402 by rotating the lens holder 401 in the mounting hole D, and then can adjust the distance between the lens assembly 400 and the fluorescent assembly 200.

[0045] Optionally, please refer to Figure 6 and Figure 7Since there is no enough adjustment space for the end of the lens holder 401 close to the fluorescent component 200 after the light source system 000 is assembled, the operator can adjust the positions of the lenses by adjusting tools on the side of the lens holder 401 away from the fluorescent component 200, that is, the end of the lens holder 401 close to the laser 300.

[0046] For example, the end of the lens holder 401 close to the laser 300 in the lens component 400 can have a plurality of adjusting grooves C, and each adjusting groove C can be used for clamping with the adjusting tool to enable the adjusting tool to drive the lens holder 401 to rotate in the mounting hole D. In this way, the operator can more conveniently control the lens holder 401 to rotate in the mounting hole D with the help of the adjusting tool.

[0047] Optionally, as shown in Figure 5 , the first fixing frame 101 in the shell 100 further has a gap L in communication with the mounting hole D, and at least one adjusting groove C in the plurality of adjusting grooves C is located in the gap L. That is, at least part of the adjusting grooves C in the plurality of adjusting grooves C can be exposed from the gap L. In this way, the operator can clamp the adjusting groove C exposed from the gap L with the adjusting tool, so as to more conveniently control the lens holder 401 to rotate in the mounting hole D.

[0048] In order to more clearly show the assembly relationship between the lens group 402 and the lens holder 401, please refer to Figure 8 , Figure 8 is an assembly schematic view of a lens group and a lens holder provided by the embodiment of the present application. The number of lenses in the lens group 402 can be multiple, and the lens holder 401 can have a plurality of lens mounting grooves 401a corresponding to the lenses in the lens group 402 one by one. The operator can install the lenses into the corresponding lens mounting grooves 401a and fixedly connect the lenses with the inner walls of the lens mounting grooves 401a, for example, after installing the lenses into the lens mounting grooves 401a, the operator can fixedly connect the inner walls of the lens mounting grooves 401a by means of dispensing. In this way, the lens group 402 can be fixedly connected with the lens holder 401 to form the lens component 400.

[0049] In the embodiment of the present application, please refer to Figure 9 , Figure 9 is another Figure 1 explosion view of a light source system. The side of the second fixing frame 102 close to the first fixing frame 101 in the shell 100 can have a support seat Z. Here, the light source system 000 can further include a mirror group 500 fixed on the support seat Z.

[0050] In the present application, in order to more clearly show the structure of the laser 300, please refer toFigure 10 , Figure 10 is a top view of a laser provided by an embodiment of the present application. The laser 300 can have a plurality of laser units. Some of the laser units 301a in the plurality of laser units 301 are configured to emit laser light directly to the lens assembly 402, and the other laser units 301b are configured to emit laser light to the mirror assembly 500, which is configured to guide the received laser light to the lens assembly 402. In this way, laser beams provided by each of the laser units 301 on the same laser 300 can be guided to the same lens assembly 402, and there is no need to set multiple lens assemblies 402 to converge laser beams provided by each of the laser units 301, thereby simplifying the assembly process of the light source system 000 and ensuring that the light source system 000 has a small size, and thus the laser projection device has a small size.

[0051] As shown in Figure 10 and Figure 11 , Figure 11 is Figure 9 a light path schematic diagram of the light source system. The laser 300 can be provided with two rows of laser units 301. The laser beams emitted by the first row of laser units 301a can be directly emitted to the lens assembly 402. The laser beams emitted by the second row of laser units 301b are first emitted in the mirror assembly 500 and then guided to the lens assembly 402 by the mirror assembly 500. In this way, the laser beams emitted by the first row of laser units 301a and the second row of laser units 301b can be converged by the lens assembly 402 and then focused on the fluorescent layer S of the fluorescent wheel 202.

[0052] Optionally, as shown in Figure 11 , the mirror assembly 500 can include a first mirror 501 and a second mirror 502 arranged oppositely. The first mirror 501 and the second mirror 502 can be arranged in parallel. Here, the reflecting surface of the first mirror 501 faces the laser 300 and the second mirror 502, and the reflecting surface of the second mirror 502 faces the lens assembly 400 and the first mirror 501. Through such a positional relationship, the first mirror 501 and the second mirror 502 can guide the laser beams emitted by the second row of laser units 301 in the laser 300 to the lens assembly 402.

[0053] As an example, since the reflecting surface of the first mirror 501 faces the laser 300 and the second mirror 502, the laser beams emitted by the second row of laser units 301 can be reflected by the first mirror 501 to the second mirror 502. Since the reflecting surface of the second mirror 502 faces the lens assembly 400 and the first mirror 501, the laser beams from the first mirror 501 can be reflected by the second mirror 502 to the lens assembly 400.

[0054] In the embodiment of the present application, as shown in Figure 12 Figure 12 is an assembly schematic diagram of the mirror group and the second fixing frame provided by the embodiment of the present application. Since the first fixing frame 101 and the second fixing frame 102 in the shell 100 are an integral structure, the operation space between the first fixing frame 101 and the second fixing frame 102 is small. In order to ensure that the first mirror 501 and the second mirror 502 can be stably assembled on the second fixing frame 102, the support seat Z can have: a first assembly groove U1 and a second assembly groove U2 that are in communication with each other, the first mirror 501 is fixed in the first assembly groove U1, and the second mirror 502 is fixed in the second assembly groove U2. Wherein, the first assembly groove U1 is closer to the bottom of the shell 100 relative to the second assembly groove U2, and the length of the first mirror 501 is less than the length of the second mirror 502. In this way, the assembly process of the first mirror 501 and the second mirror 502 can be more efficient.

[0055] For example, when assembling the first mirror 501 and the second mirror 502, the first mirror 501 can be fixed in the first assembly groove U1 first, and the second mirror 502 can be fixed in the second assembly groove U2. Here, since the first mirror 501 and the second mirror 502 each have a corresponding assembly groove, and there is no spatial overlap between the assembly grooves, it can be ensured that the first mirror 501 and the second mirror 502 can be efficiently and quickly installed in the corresponding assembly grooves. Since the second row of laser units 301b in the laser 300 is closer to the bottom of the shell 100, the first assembly groove U1 is closer to the bottom of the shell 100 relative to the second assembly groove U2, so that the first mirror 501 can reflect all the laser beams emitted by the second row of laser units 301b to the second mirror 502.

[0056] In the embodiment of the present application, please refer to Figure 13 and Figure 14 , Figure 13 is an assembly schematic diagram of the fluorescent assembly and the first fixing frame provided by the embodiment of the present application, Figure 14 ​is another assembly view of the fluorescent assembly and the first fixing frame from another perspective provided in the embodiments of the present application. The side of the first fixing frame 101 away from the second fixing frame 102 has a first accommodating groove 101a, and the first accommodating groove 101a is in communication with the mounting hole D. The side of the support shell 201 in the fluorescent assembly 200 close to the first fixing frame 101 has a second accommodating groove 201a. After the support shell 201 is connected with the first fixing frame 101, the second accommodating groove 201a and the first accommodating groove 101a are used to enclose a closed space, and the fluorescent wheel 202 is located in the closed space. In this way, the fluorescent wheel 202 in the fluorescent assembly 200 can be protected, so that the fluorescent area on the fluorescent wheel 202 is not affected by dust or water vapor in the external environment entering the light source system 000.

[0057] Optionally, the second accommodating groove 201a in the support shell 201 can have a protruding structure, wherein the protruding structure can have a first mounting hole M1, and the fluorescent wheel 202 has a second mounting hole M2 corresponding to the first mounting hole M1. When installing the fluorescent assembly 200, the operator can first align the second mounting hole M2 on the fluorescent wheel 202 with the first mounting hole M1 on the protruding structure in the support shell 201, and then connect the fluorescent wheel 202 with the support shell 201 through a screw.

[0058] Optionally, as shown in Figure 14 The fluorescent wheel 202 can have a connecting piece Q, which can be an integrated wire harness. The fluorescent wheel can be electrically connected with other components in the laser projection device through the connecting piece Q. For example, the side of the support shell 201 can have a wiring hole X. After the fluorescent wheel 202 is connected with the support shell 201, the operator can extend the connecting piece Q from the wiring hole X of the support shell 201, and connect the connecting piece Q with other components in the laser projection device.

[0059] In the embodiments of the present application, please refer to Figure 13 and Figure 14The side of the first fixing frame 101 away from the second fixing frame 102 can also have a first positioning column 101b and a first fastening hole 101c. The side of the support shell 201 close to the first fixing frame 101 can also have a first positioning hole 202b matched with the first positioning column 101b, and a first through hole 202c communicated with the first fastening hole 101c. The first positioning column 101b can pass through the first positioning hole 202b, and the light source system 000 can further include a first fastener for fastening connection with the first fastening hole 101c after passing through the first through hole 202c. In this way, the precise positioning between the support shell 201 and the first fixing frame 101 can be ensured through the cooperation of the first positioning column 101b and the first positioning hole 202b, so that the assembly error between the fluorescent assembly 200 and the lens assembly 400 is small. And through the fastening connection of the first fastener, the connection between the support shell 201 and the first fixing frame 101 is more reliable.

[0060] For example, the number of the first positioning column 101b and the first positioning column 101b and the number of the first fastening hole 101c and the first through hole 202c can be multiple. When assembling the support shell 201 and the first fixing frame 101, the operator can one-to-one correspondence between the multiple first positioning columns 101b and the multiple first positioning columns 101b, and each first positioning column 101b is inserted into the corresponding first positioning hole 202b. In this way, the support shell 201 and the first fixing frame 101 can be pre-connected. Here, the number of the first fastener can also be multiple. Through the cooperation of the first positioning column 101b and the first positioning hole 202b, the support shell 201 and the first fixing frame 101 are pre-connected, and the operator can pass the multiple first fasteners through the multiple first through holes 202c and the multiple fastening holes corresponding to each first through hole 202c, so that the support shell 201 and the first fixing frame 101 are fastened.

[0061] Optionally, the first fixing frame 101 can have a plurality of circular bosses, and the plurality of first through holes 202c can be located on the plurality of circular bosses. Here, the center of the first through hole 202c can be on the same central axis as the center of the circular boss. In this way, the operator can more efficiently align the first through hole 202c with the first fastening hole 101c, thereby improving the assembly efficiency of the light source system 000.

[0062] Optionally, as shown in Figure 15 Figure 15 ​is a second fixed frame and laser assembly schematic diagram provided by an embodiment of the present application. The second fixed frame 102 has a second positioning column 102b and a second fastening hole 102c on the side away from the first fixed frame 101. The laser 300 has a second positioning hole 300a matched with the second positioning column 102b and a second through hole 300b communicated with the second fastening hole 102c on the side close to the second fixed frame 102. Wherein, the second positioning column 102b can pass through the second positioning hole 300a. The light source system 000 further comprises: a second fastener, which is used for fastening connection with the second fastening hole 102c after passing through the second through hole 300b.

[0064] In summary, the present application provides a light source system, which comprises: a shell, a fluorescent assembly, a laser and a lens assembly. The laser beam emitted by the laser can be incident on the lens assembly, and the lens group in the lens assembly can converge the laser beam. The converged laser beam can be incident on the fluorescent layer of the fluorescent wheel. In this way, the laser beam emitted by the laser can be focused on the fluorescent layer of the fluorescent wheel by the lens group in the lens assembly, so that the fluorescent layer can better emit fluorescent light under the excitation of the laser. After the lens assembly is assembled on the shell, if the operator finds that the assembly precision between the lens assembly and the fluorescent assembly is low, the operator can adjust the distance between the lens assembly and the fluorescent assembly by controlling the lens support in the lens assembly to move along the optical axis of the lens group in the mounting hole of the shell, so that the lens group in the lens assembly can better focus the laser beam on the fluorescent layer of the fluorescent wheel, effectively improving the excitation efficiency of the fluorescent layer in the fluorescent wheel to the laser, and thus making the effect of the light beam output from the light source system to the optical machine system better.
