DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0050] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific processes and examples of materials, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0051] The embodiments of the present application provide a laser emission component and a lighting device, which are described in detail below.

[0052] First, an embodiment of the present application provides a laser emitting component.

[0053] Figure 1 A schematic structural diagram of an embodiment of a laser emission assembly provided in an embodiment of the present application, wherein the first reflector is in a reflecting position. Figure 2 for Figure 1 A schematic diagram of the structure when the first reflector of the laser emission assembly is in the avoidance position. Figure 1 and Figure 2 As shown, the laser emitting assembly 110 includes a controller 111 and at least one light emitting control structure 112. The light emitting control structure 112 includes a laser chip module 1121. The laser chip module 1121 is used to emit laser. The controller 111 is electrically connected to the laser chip module 1121 to control the laser chip module 1121 to turn on or off. When the controller 111 controls the laser chip module 1121 to turn on, the laser chip module 1121 emits laser. When the controller 111 controls the laser chip module 1121 to turn off, the laser chip module 1121 stops emitting light.

[0054] Continue to refer to Figure 1 and Figure 2 The light output control structure 112 may also include a first driving member 1122, a first reflector 1123 and a first laser detector 1124. The first laser detector 1124 is located on the output optical path of the laser chip module 1121 so that the first laser detector 1124 can receive the laser emitted by the laser chip module 1121. The first driving member 1122 is connected to the first reflector 1123 and is used to drive the first reflector 1123 to a reflective position (such as Figure 1 as shown) and avoidance position (as shown Figure 2 1121 and the first laser detector 1124, wherein when the first reflector 1123 is in the reflecting position, the first reflector 1123 is located between the laser chip module 1121 and the first laser detector 1124, and is used to reflect the laser to the output end of the laser emitting assembly 110, so that the laser emitted by the laser chip module 1121 is emitted from the output end of the laser emitting assembly 110. However, since the first reflector 1123 located between the laser chip module 1121 and the first laser detector 1124 reflects the laser to the output end of the laser emitting assembly 110, the first laser detector 1124 cannot receive the laser.

[0055] When the first reflector 1123 is in the avoidance position, it avoids the laser emitted by the corresponding laser chip module 1121. At this time, the laser emitted by the laser chip module 1121 is emitted to the first laser detector 1124 and received by the first laser detector 1124. The first laser detector 1124 is used to receive the laser and output a corresponding stop light signal to the controller 111, so that the controller 111 controls the laser chip module 1121 to stop emitting light.

[0056] The laser emitting assembly 110 provided in the embodiment of the present application drives the first reflector 1123 to move between the reflection position and the avoidance position through the first driving member 1122. When the first reflector 1123 is in the reflection position, the laser emitted by the laser chip module 1121 can be reflected to the output end of the laser emitting assembly 110 through the first reflector 1123, so as to realize the light emission of the laser emitting assembly 110. When the first reflector 1123 is in the avoidance position, the laser emitted by the laser chip module 1121 can be irradiated to the first laser detector 1124, the first laser detector 1124 receives the laser, and outputs a corresponding stop light signal to the controller 111, so that the controller 111 controls the laser chip module 1121 to stop emitting light, so as to realize the stop light of the laser emitting assembly 110.

[0057] After the first reflector 1123 switches from the reflection position to the avoidance position, the first laser detector 1124 feeds back a stop light signal to the controller 111, so that the laser chip module 1121 can be quickly controlled to stop emitting light, thereby preventing the laser emitting component 110 from continuing to emit light, and the sensitivity of the light emission control of the laser emitting component 110 is relatively high.

[0058] Among them, the number of light control structures 112 can be one or more. When the number of light control structures 112 is multiple, the controller 111 is electrically connected to the laser chip modules 1121 of the multiple light control structures 112. The first driving member 1122 of each light control structure 112 can drive the corresponding first reflector 1123 to move between the reflection position and the avoidance position. When the first driving member 1122 of a light control structure 112 drives the corresponding first reflector 1123 to move from the reflection position to the avoidance position, the first laser detector 1124 of the light control structure 112 receives the laser and outputs the corresponding stop light signal to the controller 111, so that the controller 111 controls the laser chip module 1121 of the light control structure 112 to stop emitting light. Therefore, when the laser emitting assembly 110 includes multiple light control structures 112, the sensitivity of the light emission control of the laser emitting assembly 110 can be improved by controlling whether the laser chip module 1121 of each light control structure 112 emits light or not.

[0059] In addition, the first driving member 1122 can be used to drive the first reflector 1123 to rotate between the reflection position and the avoidance position, or the first driving member 1122 can be used to drive the first reflector 1123 to slide between the reflection position and the avoidance position. It is only necessary to enable the first reflector 1123 to switch between the reflection position and the avoidance position.

[0060] In some embodiments, the first driving member 1122 can be used to drive the first reflector 1123 to rotate between the reflection position and the avoidance position, and the rotation axis of the first reflectors 1123 of the multiple light output control structures 112 extend in the same direction. The first driving member 1122 can be any component such as a driving motor, a pneumatic cylinder, a hydraulic cylinder, etc. that can drive the first reflector 1123 to rotate between the reflection position and the avoidance position. Alternatively, the first driving member 1122 can be a transmission member connected to the first reflector 1123, which is used to receive the driving force applied by the operator and transmit the driving force to the first reflector 1123 to drive the first reflector 1123 to rotate between the reflection position and the avoidance position.

[0061] In some embodiments, when the first reflectors 1123 of the plurality of light output control structures 112 are in the reflecting position, the directions of the lasers reflected by the first reflectors 1123 are consistent, so that the first reflectors 1123 in the reflecting position can reflect the lasers emitted by the corresponding laser chip modules 1121 to the output end of the laser emitting assembly 110.

[0062] Specifically, a plurality of light control structures 112 are sequentially arranged along a first direction, and a laser chip module 1121, a first reflector 1123, and a first laser detector 1124 of each light control structure 112 are sequentially arranged along a second direction, and the first direction is perpendicular to the second direction. When the first reflector 1123 is in a reflecting position, it is used to reflect the laser emitted by the corresponding laser chip module 1121 along the first direction to the output end of the laser emitting assembly 110.

[0063] In some embodiments, the controller 111 may include a first power supply 1111 electrically connected to the laser chip module 1121, and the controller 111 is used to control the first power supply 1111 to stop supplying power to the laser chip module 1121, so as to control the laser chip module 1121 to stop emitting light. Specifically, when the controller 111 receives the stop light signal output by the first laser detector 1124, the controller 111 controls the first power supply 1111 to stop supplying power to the laser chip module 1121 corresponding to the first laser detector 1124, so as to control the laser chip module 1121 corresponding to the first laser detector 1124 to stop emitting light.

[0064] Among them, when the laser emitting component 110 includes multiple light output control structures 112, the first power supply 1111 is electrically connected to the laser chip module 1121 of each light output control structure 112, so that the controller 111 controls the first power supply 1111 to stop supplying power to the corresponding laser chip module 1121, so that the corresponding laser chip module 1121 stops emitting light.

[0065] In other embodiments, Figures 6 to 10As shown, the light output control structure 112 may further include a switching element 1125, which is connected to the first laser detector 1124 and is used to drive the first laser detector 1124 to a detection position (such as Figure 7 ) and the spectral position (as shown Fig. 9 When the first laser detector 1124 is in the detection position, as shown in Figure 6 , Figure 7 , Figure 8 and Fig.10 As shown, the first laser detector 1124 is located on the optical path of the output end of the laser chip module 1121 and is used to receive laser light. When the first laser detector 1124 is in the light splitting position, the laser light is avoided. At this time, when the first reflector 1123 is in the avoidance position, the laser light emitted by the laser chip module 1121 will not be received by the first laser detector 1124. Therefore, the first laser detector 1124 will not output the corresponding stop light signal to the controller 111, so that the controller 111 controls the laser chip module 1121 to stop emitting light.

[0066] The laser emitting assembly 110 further includes a light splitting output structure 160. When the first laser detector 1124 is in the light splitting position, it avoids the laser, and the output end of the laser chip module 1121 is optically connected to the input end of the light splitting output structure 160. Figure 8 and Fig. 9 As shown, when the first laser detector 1124 is in the splitting position, the first laser detector 1124 will not output a corresponding stop light signal to the controller 111, the laser chip module 1121 will continue to emit light, and the laser emitted by the laser chip module 1121 will be transmitted from its output end to the input end of the splitting output structure 160, and transmitted from the output end of the splitting output structure 160, thereby splitting the laser emitted by the laser emitting component 110, so that the laser emitted by the laser emitting component 110 is emitted from the output end of the laser emitting component 110, and / or, the laser emitted by the laser emitting component 110 is emitted from the output end of the splitting output structure 160.

[0067] Therefore, when the output end of the laser emitting component 110 does not need to output laser, or the amount of laser output from the output end of the laser emitting component 110 is reduced, the laser emitted by some laser chip modules 1121 of the laser emitting component 110 can be transmitted to the input end of the spectroscopic output structure 160 and output from the output end of the spectroscopic output structure 160, so as to achieve full utilization of each laser chip module 1121 of the laser emitting component 110.

[0068] In some embodiments, the laser emission assembly 110 includes a plurality of light emission control structures 112, and the controller 111 is electrically connected to the laser chip modules 1121 of the plurality of light emission control structures 112. The light splitting output structure 160 includes a plurality of input ends, and the output ends of the laser chip modules 1121 of the plurality of light emission control structures 112 are used to be optically connected in a one-to-one correspondence with the plurality of input ends of the light splitting output structure 160. Thus, the laser light emitted by a portion of the laser chip modules 1121 of the laser emission assembly 110 can be emitted from the output end of the laser emission assembly 110, while the laser light emitted by another portion of the laser chip modules 1121 can be emitted from the output end of the light splitting output structure 160.

[0069] The light splitting output structure 160 may include a plurality of first collimating lenses 161 and a first beam combiner 162, the output ends of the laser chip modules 1121 of the plurality of light output control structures 112 are used to be optically connected to the input ends of the plurality of first collimating lenses 161, and the output ends of the plurality of first collimating lenses 161 are used to be optically connected to the input ends of the first beam combiner 162. When the first reflector 1123 of the light output control structure 112 is in the avoidance position and the first laser detector 1124 is in the light splitting position, the laser emitted from the output end of the laser chip module 1121 of the light output control structure 112 can be transmitted to the input end of the corresponding first collimating lens 161, and after being transmitted from the output end of the corresponding first collimating lens 161 to the first beam combiner 162, it is output from the output end of the first beam combiner 162.

[0070] When the first reflectors 1123 of the multiple light output control structures 112 are in the avoidance position and the first laser detector 1124 is in the splitting position, the laser emitted from the output end of the laser chip module 1121 of the multiple light output control structures 112 can be transmitted to the input end of the corresponding first collimating lens 161, and transmitted from the output end of the corresponding first collimating lens 161 to the first beam combiner 162 for beam combining, and then output from the output end of the first beam combiner 162.

[0071] In some embodiments, the output end of the first collimating lens 161 may be connected to the input end of the first beam combiner 162 via an optical fiber optical path. Specifically, the output ends of the plurality of first collimating lenses 161 are connected to the input end optical path of the first beam combiner 162 via different light beams.

[0072] In other embodiments, Fig.14As shown, the controller 111 can include a control module 1112 electrically connected to the first power supply 1111, the number of the control modules 1112 is equal to the number of the light output control structure 112, and the control modules 1112 are electrically connected to the laser chip modules 1121 of the light output control structure 112 in a one-to-one correspondence, so that the control module 1112 controls the opening or closing of the laser chip module 1121 to make the laser chip module 1121 emit light or stop emitting light.

[0073] Among them, the first laser detector 1124 of the light control structure 112 is electrically connected to the corresponding control module 1112. When the laser chip module 1121 of the light control structure 112 emits light normally and the first laser detector 1124 is in the detection position, after the first reflector 1123 moves from the reflection position to the avoidance position, the laser emitted by the laser chip module 1121 of the light control structure 112 will irradiate the first laser detector 1124. The first laser detector 1124 receives the laser and outputs a corresponding stop light signal to the control module 1112 of the controller 111, so that the control module 1112 controls the corresponding laser chip module 1121 to stop emitting light.

[0074] Specifically, the controller 111 includes a plurality of control modules 1112 electrically connected to the first power supply 1111, the number of the plurality of control modules 1112 is equal to the number of the plurality of light output control structures 112, and the plurality of control modules 1112 are electrically connected to the laser chip modules 1121 of the plurality of light output control structures 112 in a one-to-one correspondence, so that each control module 1112 controls the on and off state of the laser chip module 1121 of a light output control structure 112.

[0075] In some embodiments, the laser chip module 1121 may include a laser chip (not shown in the figure) for emitting laser, and a laser collimation component (not shown in the figure) arranged on the optical path of the output end of the laser chip, and the laser collimation component is used to collimate the laser emitted by the laser chip and output it from the output end of the laser collimation component.

[0076] An embodiment of the present application also provides a lighting device, which includes a laser emitting component. The specific structure of the laser emitting component refers to the above embodiment. Since the lighting device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0077] In some embodiments, Figures 3 to 5As shown, the lighting device 100 includes a laser emitting component 110 and a first lighting component 120. The input end of the first lighting component 120 is optically connected to the output end of the laser emitting component 110 through the first optical fiber 130. The laser emitting component 110 can be the laser emitting component 110 in any of the above embodiments. The laser emitted by the laser emitting component 110 is transmitted to the first lighting component 120 through the first optical fiber 130, and is output from the output end of the first lighting component 120 for lighting. Since the input end of the first lighting component 120 of the lighting device 100 is optically connected to the output end of the laser emitting component 110 through the first optical fiber 130, the first lighting component 120 of the lighting device 100 has good photoelectric isolation characteristics, and the first lighting component 120 will not generate electric sparks and electromagnetic fields, and will not have short circuit problems. Therefore, the first lighting component 120 can be used in scenes such as underwater where it is flammable and explosive, electromagnetic interference may be generated, and transmission wires may be easily corroded.

[0078] In order to maintain the photoelectric isolation characteristics of the laser emitting component 110 and the first lighting component 120 of the lighting device 100, an electric control switch is usually not set on the first lighting component 120 to control the opening and closing of the laser emitting component 110. When the lighting device 100 is used for lighting, the operator is usually near the first lighting component 120 of the lighting device 100 and keeps a certain distance from the laser emitting component 110 of the lighting device 100, which makes it difficult for the operator to conveniently open and close the laser emitting component 110 to control the light emission and stop of the first lighting component 120.

[0079] In order to solve the above problems, in some embodiments, the lighting device 100 may include a first signal light adjustment structure 121 and a first signal light detector 123, wherein the first signal light adjustment structure 121 is used to adjust the energy of the first signal light emitted to the output end of the first lighting component 120. The first signal light detector 123 is used to receive the first signal light returned by the first optical fiber 130, and to feed back a corresponding control signal to the first driver 1122 according to the energy of the first signal light, so that a corresponding number of first drivers 1122 drive the first reflector 1123 to move to an avoidance position, thereby controlling a corresponding number of laser chip modules 1121 to stop emitting light, so as to achieve the adjustment of the laser energy emitted from the output end of the laser emitting component 110 from the first lighting component 120, and further adjust the laser brightness output from the output end of the first lighting component 120.

[0080] It should be noted that when the laser emitting assembly 110 includes a light output control structure 112, when the first signal light detector 123 receives the first signal light returned by the first optical fiber 130, the first driving member 1122 of the light output control structure 112 drives the first reflector 1123 to move from the reflection position to the avoidance position, so that the first laser detector 1124 of the light output control structure 112 receives the laser and outputs a corresponding stop light signal to the controller 111, so that the controller 111 controls the laser chip module 1121 of the light output control structure 112 to stop emitting light, thereby causing the lighting device 100 to stop lighting. When the laser emitting component 110 includes multiple light output control structures 112, after the first signal light detector 123 receives the first signal light returned by the first optical fiber 130, according to the different intensities of the returned first signal light, different numbers of first driving components 1122 of the light output control structures 112 can be controlled to drive the first reflector 1123 to move from the reflection position to the avoidance position, so that different numbers of laser chip modules 1121 stop emitting light, so as to achieve the adjustment of the laser energy emitted from the output end of the laser emitting component 110.

[0081] In some embodiments, Figures 3 to 5 As shown, the first signal light adjustment structure 121 may include a first signal light source 1211 and a first reflection structure 122, the first signal light source 1211 is used to emit the first signal light, and the first reflection structure 122 includes a second reflection mirror 1221 and a second driving member 1222, as shown in FIG. Figure 4 and Figure 5 As shown, the second reflector 1221 is used to reflect the first signal light to the output end of the first lighting assembly 120, and the second driving member 1222 is used to drive the second reflector 1221 to rotate to adjust the energy of the first signal light reflected by the second reflector 1221 to the output end of the first lighting assembly 120.

[0082] It should be noted that the second driving member 1222 drives the second reflector 1221 to rotate at different angles, and the first signal light energy reflected by the second reflector 1221 to the output end of the first lighting component 120 is different. At this time, the first signal light detector 123 can control different numbers of first driving members 1122 of the light output control structure 112 to drive the second reflector 1221 to move from the reflection position to the avoidance position according to the different energies of the received first signal light.

[0083] Among them, the energy of the first signal light reflected by the second reflector 1221 to the output end of the first lighting component 120 can be 0, that is, the second reflector 1221 does not reflect the first signal light to the output end of the first lighting component 120. At this time, the first signal light detector 123 does not receive the first signal light returned by the first optical fiber 130, and the laser emitting component 110 emits light normally.

[0084] The second driving member 1222 can be any component that can drive the second reflector 1221 to rotate, such as a motor, a cylinder, a hydraulic cylinder, etc., and is not limited here. Alternatively, the second driving member 1222 is a transmission connection connected to the second reflector 1221, and the second driving member 1222 is used to receive the driving force applied by the operator and transmit the driving force to the second reflector 1221 to drive the second reflector 1221 to rotate.

[0085] In some embodiments, the output end of the first signal light source 1211 is optically connected to the input end of the first lighting assembly 120, and the first signal light emitted by the first signal light source 1211 is used to be output from the output end of the first lighting assembly 120. Figure 4 and Figure 5 As shown, when the second reflector 1221 reflects the first signal light to the output end of the first lighting component 120, the second reflector 1221 is located on the optical path of the output end of the first lighting component 120, so that the second reflector 1221 reflects at least a portion of the first signal light output from the output end of the first lighting component 120 back to the output end of the first lighting component 120.

[0086] Among them, the first signal light source 1211 can be combined with the first optical fiber 130 through the second combiner 131, so that the output end of the first signal light source 1211 is connected to the input end optical path of the first lighting component 120, and the first signal light emitted by the first signal light source 1211 can be transmitted to the first lighting component 120 through the second combiner 131 and output from the output end of the first lighting component 120.

[0087] Of course, in the embodiment of the present application, the output end of the first signal light source 1211 may not be connected to the input optical path of the first lighting component 120, but the first signal light source 1211 may emit the first signal light to the first reflective structure 122 along another optical path. It is only necessary to enable the first reflective structure 122 to reflect the first signal light to the output end of the first lighting component 120.

[0088] In some embodiments, the second reflector 1221 may include a first dichroic mirror, which is used to reflect the first signal light and to allow the laser to pass through. Figure 4 and Figure 5 As shown, when the second reflector 1221 reflects the first signal light back to the output end of the first lighting component 120, the laser output from the output end of the first lighting component 120 can pass through the second reflector 1221, thereby preventing the second reflector 1221 from reflecting the laser to the output end of the first lighting component 120, thereby causing excessive energy of the returned light in the first optical fiber 130, thereby causing damage to the laser emitting component 110.

[0089] Specifically, the first signal light is a light with a wavelength of 1550 nm or other wavelengths, and the wavelength of the first signal light is different from the wavelength of the laser. The laser light generated by the laser emitting assembly 110 is blue light or other color light. The second driving member 1222 is used to receive the force applied by the operator to drive the second reflector 1221 to rotate.

[0090] In some embodiments, Figures 3 to 5 As shown, the lighting device 100 further includes a first fluorescence conversion component 140 disposed on the output optical path of the first lighting component 120. The first fluorescence conversion component 140 is used to receive laser light and convert the color of part of the laser light. Thus, after the laser light output from the output end of the first lighting component 120 is irradiated to the first fluorescence conversion component 140, part of the laser light is converted into light of other colors by the first fluorescence conversion component 140, while the color of the other part of the laser light is not changed, and the two colors of light are mixed to form light of a new color.

[0091] Specifically, the laser emitted by the laser emitting component 110 of the lighting device 100 is a blue laser. After the blue laser is transmitted from the output end of the first lighting component 120 to the first fluorescent conversion component 140, a portion of the blue laser is converted into yellow light, and the yellow light is mixed with the blue laser to form high-brightness white light.

[0092] In some embodiments, the first reflective structure 122 is disposed between the first lighting component 120 and the first fluorescence conversion component 140. Specifically, when the second reflector 1221 of the first reflective structure 122 reflects the first signal light, the second reflector 1221 is located on the optical path between the first lighting component 120 and the first fluorescence conversion component 140. A first light homogenizing component 150 is further disposed on the side of the first fluorescence conversion component 140 away from the first lighting component 120, and the first light homogenizing component 150 is used to homogenize the mixed light of the laser output from the output end of the first lighting component 120 and the converted light after the color conversion of the first fluorescence conversion component 140, so as to make the illumination of the lighting device 100 more uniform.

[0093] In some embodiments, Figures 3 to 5 As shown, the lighting device 100 includes a second dichroic mirror 124 disposed on the optical path of the output end of the laser emitting component 110, and the second dichroic mirror 124 is used to transmit the laser light and to reflect the first signal light returned by the first optical fiber 130 to the first signal light detector 123. Thus, the laser light emitted by the laser emitting component 110 can pass through the second dichroic mirror 124, and then be transmitted to the first lighting component 120 through the first optical fiber 130, and then be emitted from the output end of the first lighting component 120. The first signal light returned from the first optical fiber 130 can be reflected by the second dichroic mirror 124 to the first signal light detector 123, and then be received by the first signal light detector 123.

[0094] In some embodiments, the lighting device 100 includes a third collimating lens 132 disposed on the optical path between the second dichroic mirror 124 and the input end of the first optical fiber 130 , and the third collimating lens 132 is used to collimate the laser emitted from the second dichroic mirror 124 to the input end of the first optical fiber 130 .

[0095] In some embodiments, the first signal light source 1211 includes a first signal light emitter 1212 and a second power supply 1213, and the second power supply 1213 is electrically connected to the first signal light emitter 1212 to supply power to the first signal light emitter 1212, and the first signal light emitter 1212 is used to emit a first signal light. The first signal light emitter 1212 is supplied with power by the second power supply 1213, and after the laser emission component 110 stops working, the first signal light emitter 1212 can still stably emit the first signal light, so that the first signal light detector 123 continues to receive the first signal light, so that the laser emission component 110 continues to remain in a stopped state; when the first reflective structure 122 does not reflect the first signal light to the output end of the first lighting component 120, the first signal light detector 123 does not continue to receive the first signal light, so that the laser emission component 110 starts to emit light.

[0096] In some embodiments, Figures 10 to 13 As shown, the lighting device 100 further includes a second lighting assembly 170, the input end of which is optically connected to the output end of the light splitting output structure 160 through a second optical fiber 171. Fig.12 As shown, when the output end of the light splitting output structure 160 of the lighting device 100 outputs laser light, the laser light can be transmitted to the second lighting component 170 through the second optical fiber 171 and illuminated by the second lighting component 170 .

[0097] In some embodiments, the lighting device 100 also includes a second signal light adjustment structure 172 and a second signal light detector 173. The second signal light adjustment structure 172 is used to adjust the second signal light energy emitted to the output end of the second lighting component 170. The second signal light detector 173 is used to receive the second signal light returned by the second optical fiber 171, and to feed back a corresponding control signal to the controller 111 based on the energy of the second signal light, so that the controller 111 controls the corresponding laser chip module 1121 to stop emitting light. Alternatively, the second signal light detector 173 is used to receive the second signal light returned by the second optical fiber 171, and to feed back a corresponding control signal to the switching element 1125 based on the energy of the second signal light, so that a corresponding number of switching elements 1125 drive the corresponding first laser detectors 1124 to move to the detection position.

[0098] Thus, the second signal light detector 173 is used to receive the second signal light returned by the second optical fiber 171, and feed back the corresponding control signal to the controller 111 according to the energy of the second signal light, so that the controller 111 controls the corresponding number of laser chip modules 1121 to stop emitting light. Alternatively, the first laser detector 1124 can also receive the laser emitted by the corresponding laser chip module 1121, and output the corresponding stop light signal to the controller 111, so that the controller 111 controls the laser chip module 1121 of the light output control structure 112 to stop emitting light.

[0099] It should be noted that when only the laser chip module 1121 of one light output control structure 112 emits laser to the input end of the splitter output structure 160, after the second signal light detector 173 receives the second signal light returned by the second optical fiber 171, it feeds back a corresponding control signal to the switching element 1125 or the controller 111 based on the energy of the second signal light, so that the switching element 1125 drives the corresponding first laser detector 1124 to move to the detection position, so that the laser chip module 1121 of the light output control structure 112 stops emitting light.

[0100] When the laser chip modules 1121 of the plurality of light-exit control structures 112 emit lasers to the input end of the light-splitting output structure 160, after receiving the second signal light returned by the second optical fiber 171, the second signal light detector 173 feeds back corresponding control signals to the switch elements 1125 of the light-exit control structures 112 of different numbers according to the energy of the second signal light, so that the switch elements 1125 of the light-exit control structures 112 of different numbers drive the corresponding first laser detectors 1124 to move to the detection position, so that the laser chip modules 1121 of the light-exit control structures 112 of different numbers stop emitting light, so as to adjust the illumination brightness of the second illumination component 170. Alternatively, the second signal light detector 173 feeds back corresponding control signals to the controller 111 according to the energy of the second signal light, so that the controller 111 controls the laser chip modules 1121 of the light-exit control structures 112 of different numbers to stop emitting light, so as to adjust the illumination brightness of the second illumination component 170.

[0101] In some embodiments, Fig.14 and Fig.15 As shown, the controller 111 may include a control module 1112 electrically connected to the first power supply 1111, the number of the control modules 1112 is equal to the number of the light output control structure 112, and the control modules 1112 are electrically connected to the laser chip modules 1121 of the light output control structure 112 in a one-to-one correspondence, so that the control module 1112 controls the opening or closing of the laser chip module 1121 to make the laser chip module 1121 emit light or stop emitting light.

[0102] Among them, the second signal light detector 173 is electrically connected to each control module 1112. When the laser chip module 1121 of the light output control structure 112 emits light normally, after the second signal light detector 173 receives the second signal light returned by the second optical fiber 171, the corresponding control signal is fed back to the corresponding number of control modules 1112 according to the energy of the second signal light, so that the corresponding number of control modules 1112 control the corresponding laser chip modules 1121 to stop emitting light.

[0103] In some embodiments, the second signal light adjustment structure 172 can include a second signal light source 1721 and a second reflection structure 1722, the second signal light source 1721 is used to emit a second signal light, the second reflection structure 1722 includes a third reflector 1723 and a third driving member 1724, the third reflector 1723 is used to reflect the second signal light to the output end of the second lighting component 170, and the third driving member 1724 is used to drive the third reflector 1723 to rotate to adjust the second signal light energy reflected by the third reflector 1723 to the output end of the second lighting component 170.

[0104] It should be noted that the third driving member 1724 drives the third reflector 1723 to rotate at different angles, and the energy of the second signal light reflected by the third reflector 1723 to the output end of the second lighting component 170 is different. At this time, the second signal light detector 173 can control different numbers of switching members 1125 of the light output control structure 112 to drive the corresponding first laser detector 1124 to move from the splitting position to the detection position according to the different energy of the second signal light received. Alternatively, the second signal light detector 173 can control different numbers of laser chip modules 1121 of the light output control structure 112 to stop emitting light according to the different energy of the second signal light received.

[0105] Among them, the energy of the second signal light reflected by the third reflector 1723 to the output end of the second lighting component 170 can be 0, that is, the third reflector 1723 does not reflect the second signal light to the output end of the second lighting component 170. At this time, the second signal light detector 173 does not receive the second signal light returned by the second optical fiber 171, and the splitting output structure 160 emits light normally.

[0106] The third driving member 1724 can be any component that can drive the third reflector 1723 to rotate, such as a motor, a cylinder, a hydraulic cylinder, etc., and is not limited here. Alternatively, the third driving member 1724 is a transmission connection connected to the third reflector 1723, and the third driving member 1724 is used to receive the driving force applied by the operator and transmit the driving force to the third reflector 1723 to drive the third reflector 1723 to rotate.

[0107] In some embodiments, the output end of the second signal light source 1721 is in optical communication with the input end of the second lighting assembly 170, and the second signal light emitted by the second signal light source 1721 is used to be output from the output end of the second lighting assembly 170. When the third reflector 1723 reflects the second signal light to the output end of the second lighting assembly 170, the third reflector 1723 is located on the optical path of the output end of the second lighting assembly 170, so that the third reflector 1723 reflects at least a portion of the second signal light output from the output end of the second lighting assembly 170 back to the output end of the second lighting assembly 170.

[0108] Among them, the second signal light source 1721 can be combined with the second optical fiber 171 through a combiner, or the second signal light source 1721 can be directly connected to the input optical path of the second lighting component 170 through a separate optical fiber. It is only necessary to output the second signal light emitted by the second signal light source 1721 from the output end of the second lighting component 170.

[0109] Of course, in the embodiment of the present application, the output end of the second signal light source 1721 may not be connected to the input optical path of the second lighting component 170, but the second signal light source 1721 may emit the second signal light to the second reflective structure 1722 along another optical path. It is only necessary to enable the second reflective structure 1722 to reflect the second signal light to the output end of the second lighting component 170.

[0110] In some embodiments, the third reflector 1723 includes a third dichroic mirror, which is used to reflect the second signal light and to allow the laser to pass through. Therefore, when the third reflector 1723 reflects the second signal light back to the output end of the second lighting assembly 170, the laser output from the output end of the second lighting assembly 170 can pass through the third reflector 1723, avoiding the problem that the third reflector 1723 also reflects the laser to the output end of the second lighting assembly 170, which causes the return light energy in the second optical fiber 171 to be too large, thereby causing damage to the laser emitting assembly 110.

[0111] Specifically, the second signal light is a light with a wavelength of 1550 nm or other wavelengths, and the wavelength of the second signal light is different from the wavelength of the laser. The laser light generated by the laser emitting assembly 110 is blue light or light of other colors. The third driving member 1724 is used to receive the force applied by the operator to drive the third reflector 1723 to rotate.

[0112] In some embodiments, Fig.14 and Fig.15As shown, the lighting device 100 includes a fourth dichroic mirror 174 located on the optical path between the output end of the light splitting output structure 160 and the input end of the second optical fiber 171. The fourth dichroic mirror 174 is used to transmit the laser light and to reflect the second signal light returned by the second optical fiber 171 to the first signal light detector 123. Thus, the laser light output from the output end of the light splitting output structure 160 can pass through the fourth dichroic mirror 174, and then be transmitted to the second lighting component 170 through the second optical fiber 171, and then be emitted from the output end of the second lighting component 170. The second signal light returned from the second optical fiber 171 can be reflected by the fourth dichroic mirror 174 to the second signal light detector 173, and then be received by the second signal light detector 173.

[0113] In some embodiments, the lighting device 100 further includes a second fluorescence conversion component 175 disposed on the output optical path of the second lighting component 170. The second fluorescence conversion component 175 is used to receive laser light and convert the color of part of the laser light. Thus, after the laser light output from the output end of the second lighting component 170 is irradiated to the second fluorescence conversion component 175, part of the laser light is converted into light of other colors by the second fluorescence conversion component 175, while the color of the other part of the laser light is not changed, and the two colors of light are mixed to form light of a new color.

[0114] In some embodiments, the second reflective structure 1722 is disposed between the second lighting component 170 and the second fluorescence conversion component 175. Specifically, when the second reflector 1221 of the second reflective structure 1722 reflects the second signal light, the second reflector 1221 is located on the optical path between the second lighting component 170 and the second fluorescence conversion component 175. A second light homogenizing component 176 is further disposed on the side of the second fluorescence conversion component 175 away from the second lighting component 170, and the second light homogenizing component 176 is used to homogenize the mixed light of the laser output from the output end of the second lighting component 170 and the converted light after the second fluorescence conversion component 175 converts the color, so as to make the illumination of the second lighting component 170 more uniform.

[0115] In some embodiments, the second signal light source 1721 includes a second signal light emitter 1725 and a third power supply 1726, and the third power supply 1726 is electrically connected to the second signal light emitter 1725 to supply power to the second signal light emitter 1725, and the second signal light emitter 1725 is used to emit the second signal light. The second signal light emitter 1725 is supplied with power by the third power supply 1726, and after the laser emission assembly 110 stops working, the second signal light emitter 1725 can still stably emit the second signal light, so that the second signal light detector 173 continues to receive the second signal light, so that the corresponding laser chip module 1121 continues to remain in the stopped state; when the second reflective structure 1722 does not reflect the second signal light to the output end of the second lighting assembly 170, the second signal light detector 173 does not continue to receive the second signal light, so that the corresponding laser chip module 1121 starts to emit light.

[0116] In some embodiments, the lighting device 100 includes a second collimating lens 177 located on an optical path between the output end of the light splitting output structure 160 and the fourth dichroic mirror 174, and a focusing lens 178 located on an optical path between the fourth dichroic mirror 174 and the input end of the second optical fiber 171. Thus, the laser light output from the output end of the light splitting output structure 160 can be collimated and focused by the second collimating lens 177 and the focusing lens 178.
