DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

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 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.

[0025] The embodiments of the present application provide a laser lighting system, which is described in detail below.

[0026] Figure 1 This is a schematic diagram of the structure of an embodiment of the laser illumination system provided in the present application. Figure 1 As shown, the laser lighting system 100 provided in the embodiment of the present application includes a laser emitting component 110 and a lighting component 130. The laser emitting component 110 is used to emit laser light, and the input end of the lighting component 130 is optically connected to the output end of the laser emitting component 110 through the optical fiber 120. Thus, the laser emitted by the laser emitting component 110 is transmitted to the lighting component 130 through the optical fiber 120, and is output from the output end of the lighting component 130 for lighting. The input end of the lighting component 130 of the laser lighting system 100 is optically connected to the output end of the laser emitting component 110 through the optical fiber 120. The lighting component 130 of the laser lighting system 100 has good photoelectric isolation characteristics. The lighting component 130 will not generate electric sparks and electromagnetic fields, and will not have short circuit problems. Therefore, the lighting component 130 can be used in scenes such as underwater where it is flammable and explosive, will generate electromagnetic interference, and is easy to corrode transmission wires.

[0027] In order to maintain the photoelectric isolation characteristics of the laser emitting assembly 110 and the lighting assembly 130 of the laser lighting system 100, an electric control switch is usually not provided on the lighting assembly 130 to control the opening and closing of the laser emitting assembly 110. When the laser lighting system 100 is used for lighting, the operator is usually near the lighting assembly 130 of the laser lighting system 100 and keeps a certain distance from the laser emitting assembly 110 of the laser lighting system 100, which makes it difficult for the operator to conveniently open and close the laser emitting assembly 110 to control the light emission and stop of the lighting assembly 130.

[0028] In order to avoid the above problems, Figure 1 and Figure 2As shown, the laser lighting system 100 provided in the embodiment of the present application may also include a switch control component 140, which is used to control the opening and closing of the laser emitting component 110, so that the operator can control the opening and closing of the laser emitting component 110 near the lighting component 130, and further control the light emission and stopping of the lighting component 130.

[0029] The switch control assembly 140 includes a signal light source 141, a switch structure 142 and a detector 143. The signal light source 141 is used to emit signal light. The switch structure 142 can be in a closed state ( Figure 2 shown) and the open state ( Figure 1 When the switch structure 142 is in the closed state, it is used to reflect the signal light to the output end of the lighting component 130. At this time, the signal light reflected to the input end of the lighting component 130 by the switch structure 142 will enter the optical fiber 120 from the input end of the lighting component 130 and form a return light transmitted from the output end of the optical fiber 120 to the input end.

[0030] The switch structure 142 is used to avoid the signal light when it is in the on state, and at this time, the switch structure 142 will not reflect the signal light to the input end of the lighting assembly 130. Of course, the switch structure 142 can also reflect the signal light to other positions when it is in the on state, as long as the signal light does not return to the optical fiber 120 from the output end of the lighting assembly 130.

[0031] The detector 143 is connected to the optical path of the optical fiber 120 and is electrically connected to the laser emitting assembly 110. The detector 143 is used to receive the signal light returned by the optical fiber 120, and to feed back the corresponding control signal to the laser emitting assembly 110 according to the signal light, so as to control the operation state of the laser emitting assembly 110. Among them, the detector 143 can feed back the corresponding control signal to the laser emitting assembly 110 according to the signal light, so that the laser emitting assembly 110 stops running, and then controls the lighting assembly 130 to stop emitting light. When the detector 143 does not receive the signal light returned by the optical fiber 120, the corresponding control signal can be fed back to the laser emitting assembly 110, so that the laser emitting assembly 110 works normally, thereby controlling the lighting assembly 130 to emit light normally.

[0032] The laser lighting system 100 provided in the embodiment of the present application emits signal light through the signal light source 141 of the switch control component 140, and switches between the closed state of reflecting the signal light to the output end of the lighting component 130 and the open state of not reflecting the signal light to the output end of the lighting component 130 through the switch structure 142, and enables the detector 143 to send a corresponding control signal to the laser emitting component 110 after receiving the signal light returned by the optical fiber 120, so as to control the operating state of the laser emitting component 110. Therefore, by controlling the open state and the closed state of the switch structure 142, the operating state of the laser emitting component 110 can be controlled, so as to control the light output state of the lighting component 130.

[0033] In some embodiments, the switch structure 142 may include a reflector 1421 and a driver 1422. The driver 1422 is connected to the reflector 1421 and is used to drive the reflector 1421 to a reflective position (eg, Figure 2 as shown) and avoidance position (as shown Figure 1 When the reflector 1421 is in the reflecting position, the reflector 1421 is used to reflect the signal light to the output end of the lighting assembly 130. At this time, the switch structure 142 is in the closed state. The detector 143 can receive the signal light returned by the optical fiber 120, and feed back the corresponding control signal to the laser emitting assembly 110 according to the signal light, so that the laser emitting assembly 110 stops running.

[0034] When the reflector 1421 is in the avoidance position, the reflector 1421 is used to avoid the signal light, so that the switch structure 142 avoids the signal light. At this time, the switch structure 142 is in the open state. The detector 143 does not receive the signal light returned by the optical fiber 120, and the laser emission component 110 emits light normally. Of course, when the switch structure 142 is in the open state, the reflector 1421 can also reflect the signal light to other positions, as long as the signal light does not return to the optical fiber 120 from the output end of the lighting component 130.

[0035] The driving member 1422 can be used to drive the reflector 1421 to rotate between the reflective position and the avoidance position. The driving member 1422 can also be used to drive the reflector 1421 to slide between the reflective position and the avoidance position. The driving member 1422 can be any component such as a motor, a cylinder, a hydraulic cylinder, etc. that can drive the reflector 1421 to move between the reflective position and the avoidance position, and is not limited here. Alternatively, the driving member 1422 is a transmission connection connected to the reflector 1421, and the driving member 1422 is used to receive the driving force applied by the operator and transmit the driving force to the reflector 1421 to drive the reflector 1421 to move between the reflective position and the avoidance position.

[0036] In some embodiments, the output end of the signal light source 141 can be connected to the optical path of the input end of the lighting assembly 130, so that the signal light emitted by the signal light source 141 is used to be output from the output end of the lighting assembly 130. When the reflector 1421 is in the reflecting position, the reflector 1421 is located on the optical path of the output end of the lighting assembly 130, so that the reflector 1421 reflects at least a portion of the signal light output from the output end of the lighting assembly 130 back to the output end of the lighting assembly 130. When the light-emitting element is in the avoiding position, the reflector 1421 avoids the optical path of the output end of the lighting assembly 130, thereby avoiding reflecting the signal light back to the output end of the lighting assembly 130.

[0037] Among them, the signal light source 141 can be combined with the optical fiber 120 through the combiner 121, so that the output end of the signal light source 141 is connected to the input end optical path of the lighting component 130, and the signal light emitted by the signal light source 141 can be transmitted to the lighting component 130 through the combiner 121 and output from the output end of the lighting component 130.

[0038] Of course, in the embodiment of the present application, the output end of the signal light source 141 may not be connected to the input optical path of the lighting component 130, but the signal light source 141 may emit the signal light to the switch structure 142 along another optical path. It is only necessary to make the switch structure 142 reflect the signal light to the output end of the lighting component 130 when it is in the closed state, and not reflect the signal light to the output end of the lighting component 130 when it is in the open state.

[0039] In some embodiments, the reflector 1421 may include a first dichroic mirror, which is used to reflect the signal light and to allow the laser to pass through. Thus, when the reflector 1421 is in the reflecting position, the reflector 1421 can reflect the signal light back to the output end of the lighting assembly 130, and the laser output from the output end of the lighting assembly 130 can pass through the reflector 1421, thereby avoiding the problem that the reflector 1421 also reflects the laser to the output end of the lighting assembly 130, which causes excessive energy of the returned light in the optical fiber 120, thereby causing damage to the laser emitting assembly 110.

[0040] Specifically, the signal light is light with a wavelength of 1550 nm or other wavelengths, and the wavelength of the 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 driving member 1422 is used to receive the force applied by the operator and drive the reflective member 1421 to rotate between the reflective position and the avoidance position.

[0041] In some embodiments, the reflector 1421 can have multiple reflective positions. When the reflector 1421 is at different reflective positions, it reflects signal lights of different energies to the output end of the lighting assembly 130. The detector 143 is used to receive signal lights of different energies returned by the optical fiber 120, and feed back different control signals to the laser emitting assembly 110 according to the signal lights of different energies, so as to control the laser emitting assembly 110 to operate at different powers, thereby emitting lasers of different powers, so as to adjust the illumination brightness through the laser lighting system 100. Specifically, the reflector 1421 can be rotated at different angles, so that the reflector 1421 has multiple reflective positions, and when the reflector 1421 is at different reflective positions, it reflects signal lights of different energies to the output end of the lighting assembly 130.

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the laser lighting system 100 further includes a fluorescence conversion component 150 disposed on the output light path of the lighting component 130. The fluorescence conversion component 150 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 lighting component 130 is irradiated to the fluorescence conversion component 150, part of the laser light is converted into light of other colors by the fluorescence conversion component 150, 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.

[0043] Specifically, the laser emitted by the laser emitting component 110 of the laser lighting system 100 is a blue laser. After the blue laser is transmitted from the output end of the lighting component 130 to the fluorescent conversion component 150, 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.

[0044] In some embodiments, the switch structure 142 is disposed between the lighting assembly 130 and the fluorescence conversion assembly 150. Specifically, when the switch structure 142 is in the closed state, it is located on the optical path between the lighting assembly 130 and the fluorescence conversion assembly 150. A light homogenizing assembly 160 is further disposed on the side of the fluorescence conversion assembly 150 away from the lighting assembly 130. The light homogenizing assembly 160 is used to homogenize the mixed light of the laser output from the output end of the lighting assembly 130 and the converted light after the color conversion of the fluorescence conversion assembly 150, so as to make the illumination of the laser lighting system 100 more uniform.

[0045] In some embodiments, Figure 1 and Figure 2As shown, the switch control component 140 further includes a second dichroic mirror 144 disposed on the optical path of the output end of the laser emitting component 110, and the second dichroic mirror 144 is used to transmit the laser light and to reflect the signal light returned from the optical fiber 120 to the detector 143. Thus, the laser light emitted by the laser emitting component 110 can pass through the second dichroic mirror 144, be transmitted to the lighting component 130 through the optical fiber 120, and be emitted from the output end of the lighting component 130. The signal light returned from the optical fiber 120 can be reflected by the second dichroic mirror 144 to the detector 143, and be received by the detector 143.

[0046] Specifically, the laser emitting assembly 110 includes a first power supply 111, a plurality of laser chips 112, and a plurality of reflectors 113. The first power supply 111 is electrically connected to the plurality of laser chips 112. The laser chips 112 are used to emit lasers. The plurality of reflectors 113 are arranged in a one-to-one correspondence with the plurality of laser chips 112, and are used to reflect the lasers to the output end of the laser emitting assembly 110. The second dichroic mirror 144 is located on the reflected light path of the plurality of reflectors 113. A collimating lens 114 is also provided on the light path between the second dichroic mirror 144 and the optical fiber 120, and the collimating lens 114 is used to collimate the lasers reflected by the plurality of reflectors 113.

[0047] In some embodiments, the detector 143 is electrically connected to the first power supply 111 of the laser emitting assembly 110, and the detector 143 is used to transmit a corresponding control signal to the first power supply 111, so that the first power supply 111 stops supplying power to the multiple laser chips 112, so that the multiple laser chips 112 stop emitting light.

[0048] Alternatively, the laser emitting assembly 110 may also include a controller (not shown in the figure), which is used to control the first power supply 111 to supply power to the multiple laser chips 112. The detector 143 is electrically connected to the controller of the laser emitting assembly 110, and the detector 143 is used to transmit a corresponding control signal to the controller, so that the controller controls the first power supply 111 to stop supplying power to the multiple laser chips 112, so that the multiple laser chips 112 stop emitting light.

[0049] In some embodiments, the signal light source 141 includes a signal light emitter 1411 and a second power supply 1412, and the second power supply 1412 is electrically connected to the signal light emitter 1411 to supply power to the signal light emitter 1411, and the signal light emitter 1411 is used to emit signal light. The signal light emitter 1411 is supplied with power by the second power supply 1412, and after the laser emission component 110 stops working, the signal light emitter 1411 can still stably emit signal light, so that when the switch structure 142 is in the closed state, the detector 143 continues to receive the signal light, so that the laser emission component 110 continues to remain in the stopped state; when the switch structure 142 is switched to the open state, the detector 143 does not continue to receive the signal light, so that the laser emission component 110 starts to emit light.

[0050] In some embodiments, Figure 3 As shown, the laser lighting system 100 can include multiple lighting components 130 and multiple switch control components 140. The input ends of the multiple lighting components 130 are connected to the output end optical path of the laser emission component 110 through the optical fiber 120 respectively. The multiple switch control components 140 are equal in number and arranged in one-to-one correspondence with the multiple lighting components 130. In this way, the laser lighting system 100 can illuminate multiple areas through the lighting components 130. Among them, the optical fibers 120 connected to the input ends of the multiple lighting components 130 can be combined by the combiner 121 and connected to the output end optical path of the laser emission component 110.
