DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
In order that the above objects, features and advantages of the present invention can be more clearly understood, a detailed description of the present invention will be given below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention, and the described embodiments are merely a subset of the embodiments of the present invention, rather than a complete embodiment. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Example one
Referring to fig. 1, a preferred embodiment of the laser fiber illumination system of the present invention includes a light source 100 and a light emitting unit 120. The light source unit 100 may be connected to the light emitting unit 120 through an optical fiber 130. The light source unit 100 is configured to generate and output laser light, and output the laser light to the light emitting unit 120 through the optical fiber 130. The light emitting unit 120 may emit the laser beam, or may emit the laser beam after converting the laser beam.
Preferably, the light source unit 100 includes a control module 102, a first driving module 104, a second driving module 106, a laser providing module 108, and a detecting module 110.
Specifically, the first driving module 104 may provide power for the laser providing module 108, and the second driving module 106 may also provide power for the laser providing module 108. In one embodiment, the first driving module 104 may provide the power to the laser providing module 108 by an alternating current (a first type of power); the second driving module 106 may provide the power for the laser providing module 108 by a battery (second type of power). In this embodiment, the first driving module 104 may be electrically connected to an external power transmission headquarters, so as to receive the electric energy transmitted by the power transmission headquarters. The second driving module 106 is used as a backup device, for example, when the first driving module 104 cannot normally provide power for the laser providing module 108, the second driving module 106 can be switched to under the control of the control module 102, that is, the second driving module 106 provides power for the laser providing module 108.
In other embodiments, the light source unit 100 may include a plurality of second driving modules 106, such that when the first driving module 104 cannot normally provide power for the laser providing module 108, one or more second driving modules 106 of the plurality of second driving modules 106 may provide power for the laser providing module 108, thereby facilitating to improve stability of the light source unit 100 outputting laser light.
In other embodiments, the first driving module 104 and the second driving module 106 may rely on the same type of power to provide power for the laser providing module 108. For example, the first driving module 104 and the second driving module 106 may both rely on ac power to provide power for the laser providing module 108.
The detection module 110 is configured to detect whether the laser providing module 108 generates laser light normally (i.e., detect an operating state of the laser providing module 108) and output a detection result signal.
Preferably, when the laser providing module 108 normally generates laser (e.g. the laser generated by the laser providing module 108 meets a predetermined requirement), the detecting module 110 does not output the detection result signal or outputs the normal detection result signal to the control module 102; when the laser providing module 108 cannot normally generate laser light (e.g., the laser providing module 108 cannot generate laser light or the generated laser light cannot meet a predetermined requirement), the detecting module 110 outputs an abnormal detection result signal to the control module 102.
The control module 102 can select the first driving module 104 or/and the second driving module 106 to provide power for the laser providing module 108 according to whether the detection module 110 outputs the abnormal detection result signal is received or not.
Preferably, when the abnormality detection result signal is received, it indicates that the first driving module 104 cannot normally generate the laser power for the laser providing unit 108, and the control module 102 can selectively supply the laser providing module 108 with the power from the second driving module 106. When the abnormality detection result signal is not received, it indicates that the first driving module 104 can normally generate the laser power for the laser providing module 108, and the control module 102 can continue to select the first driving module 104 to provide the laser power for the laser providing module.
In other embodiments, when the abnormality detection result signal is received (for example, the power provided by the first driving module 104 to the laser providing module 108 is insufficient, and the brightness of the laser generated by the laser providing module 108 may not meet a predetermined requirement), the control module 102 may further determine the type of the power relied on by the first driving module 104 and the second driving module 106; when the types of power relied on by the first driving module 104 and the second driving module 106 are the same (for example, the types of power relied on by the first driving module 104 and the second driving module 106 are both ac power), the control module 102 can control the first driving module 104 and the second driving module 106 to simultaneously provide power for the laser providing module 108, which is beneficial to reducing the shortage that the laser generated by the laser providing module 108 cannot meet the predetermined requirement due to the shortage of power provided by the first driving module 104.
The laser providing module 108 is configured to convert electrical energy into laser, and output the laser to an incident end face of the optical fiber after operations such as dodging and converging. In this embodiment, the laser providing unit 108 may include a laser, a light homogenizing member, a converging optical element, and the like, and the laser may be a laser source module including one or more laser diodes. The laser is used for generating laser, the dodging component is used for dodging the laser, and the converging optical element converges the dodged laser and outputs the converged laser to the incident end face of the optical fiber. The laser light generated by the laser light providing module 108 is transmitted through the optical fiber and then emitted from the emitting end face of the optical fiber.
The light emitting unit 120 is used to output the laser light directly or after converting the laser light. In one mode, the light emitting section 120 outputs laser light. In another embodiment, the light emitting part 120 may be provided with a wavelength conversion material that absorbs the laser light, generates a stimulated light having a wavelength different from the laser light, and outputs the stimulated light; or the wavelength conversion material absorbs part of the exciting light and converts the exciting light into stimulated light, and outputs mixed light of the exciting light and the stimulated light.
In addition, the light emitting portion 120 may further include some optical elements, such as a lens assembly, for guiding, converging, diverging, homogenizing, etc. the laser light emitted from the light emitting end face of the optical fiber.
The laser optical fiber lighting system is beneficial to improving the stability of the system by detecting the working state of the laser providing module and switching to the standby driving module to continuously provide power when the working state of the laser providing module is abnormal; in addition, when the types of the electric power depended on by the first driving module and the second driving module are the same, the first driving module and the second driving module can simultaneously provide electric power for the laser providing module, so that the defect that the laser generated by the laser providing module cannot meet the preset requirement due to the fact that the electric power provided by the first driving module is insufficient is favorably reduced, and the stability of the system can be improved.
Example two
Referring to fig. 2, a second preferred embodiment of the laser illumination system of the present invention is shown. Compared to the first preferred embodiment, in this embodiment, the detecting module 110 can also detect the operating state of the first driving module 104. When the first driving module 104 is in an abnormal state, which indicates that the first driving module 104 may not be able to provide power to the laser providing module 108, the detecting module 110 outputs the abnormal detection result signal to the control module 102, so that the control module 102 selects the first driving module 104 and the second driving module 106 or switches to the second driving module alone to provide power to the laser providing module 108. Specifically, when the first driving module 104 and the second driving module 106 are selected to supply power to the laser providing module 108 together, it needs to be determined by the control module 102 whether the first driving module 104 and the second driving module 106 depend on the same power type, and when the first driving module 104 and the second driving module 106 depend on the same power type, the first driving module 104 and the second driving module 106 can supply power to the laser providing module 108 together; if the first driving module 104 and the second driving module 106 depend on different power types, the power is switched to the second driving module 106 to supply power to the laser providing module 108. The connection relationship and functions of other elements in this embodiment are the same as those in the first embodiment, and therefore are not described herein again.
According to the laser optical fiber lighting system, the working states of the plurality of driving modules are detected, so that the standby second driving module is switched to continuously provide power when the first driving module works abnormally, and the stability of the system is improved.
EXAMPLE III
Referring to fig. 3, a laser fiber illumination system according to a third preferred embodiment of the present invention includes a light source 300 and a light emitting unit 320. The light source unit 300 may be connected to the light emitting unit 320 through an optical fiber 330. The light source 300 generates and outputs laser light, and outputs the laser light to the light emitting unit 320 through the optical fiber 330. The light emitting unit 320 may emit the laser light, or may emit the laser light after converting the laser light.
Preferably, the light source 300 includes a control module 302, a first driving module 304, a second driving module 306, a first sub-laser providing module 3081, a second sub-laser providing module 3082, a detecting module 310, and an optical fiber coupler 312.
The first sub laser light providing module 3081 may be configured to output first laser light, the second sub laser light providing module 3082 may be configured to output second laser light, and the optical fiber coupler 312 may selectively transmit the first laser light and/or the second laser light to the light emitting portion 320.
The first driving module 304 may provide power to the first sub-laser providing module 3081, and the second driving module 306 may provide power to the second laser providing module 3082. In this embodiment, the first driving module 304 may provide the power to the first sub-laser providing module 3081 by an alternating current (a first type of power). The second driving module 306 may supply the power to the second sub laser providing module 3082 by a battery (second type power). The first driving module 304 may be electrically connected to an external power transmission headquarters to receive the electric power transmitted by the power transmission headquarters. The second sub-laser providing module 3082 can be used as a backup device, for example, when the first sub-laser providing module 3081 works abnormally, the second sub-laser providing module 3082 can be switched to, i.e., output by the second sub-laser providing module 3082. In other embodiments, the first driving module 307 may also be powered by a battery to provide power for the first sub-laser providing module 3081; the second driving module may also supply power to the second sub-laser providing module 3082 by ac power.
In other embodiments, the light source 300 may include a plurality of second sub-laser providing modules and driving modules corresponding to the number of the second sub-laser providing modules, so that when the first sub-laser module 3081 works abnormally, the first sub-laser module may be switched to a part or all of the second sub-laser providing modules, thereby improving the stability of the light source outputting laser.
It is understood that when all the second sub-laser providing modules are turned on, the laser light provided by all the second sub-laser providing modules can reach the predetermined requirement.
Preferably, the detecting module 330 is configured to detect whether the first sub-laser providing module 3081 generates laser light normally (i.e. detect a working state of the first sub-laser providing module 3081), and when the first sub-laser providing module 3081 cannot generate laser light normally, the detecting module 330 outputs an abnormal detection result signal to the control module 302. In this embodiment, the detection module 330 may detect the operating state of the first sub-laser providing module 3081, and when the first sub-laser providing module 3081 is in an abnormal operation state, the detection module 330 may output the abnormal detection result signal, for example, the first sub-laser providing module 3081 cannot generate laser light or the generated laser light cannot meet a predetermined requirement. If the first sub-laser providing module 3081 is in a normal working state, for example, the first sub-laser providing module 3081 may generate stable laser, and the detecting module 330 may not output the detection result signal or output a normal detection result signal.
The control module 302 can selectively control the fiber coupler 312 to selectively output the first laser light and/or the second laser light according to whether the anomaly detection result signal output by the detection module 330 is received or not.
Preferably, when the abnormality detection result signal is received, it may indicate that the first sub laser module 3081 works abnormally, and the control module 302 controls the optical fiber coupler 312 to select a part of the second laser light provided by the second sub laser module 3082 and the first laser light output by the first sub laser module or select all of the second laser light provided by the second sub laser module 3082.
Specifically, when the abnormality detection result signal indicates that the first laser provided by the first sub-laser providing module 3081 does not meet the predetermined requirement, the control module 302 controls to electrically connect the first driving module 304 to the first sub-laser providing module 3081 and electrically connect the second driving module 306 to a part of the second sub-laser providing module 3082, and controls the optical fiber coupler 312 to select a part of the second laser output by the second sub-laser providing module 3082 and the first laser output by the first sub-laser providing module 3081, so as to enhance the brightness of the first laser through the part of the second laser to meet the predetermined requirement; when the abnormality detection result signal indicates that the first sub laser providing module 3081 cannot provide the first laser, the control module 302 controls to cut off the electrical connection between the first sub laser providing module 3081 and the first driving module 304, and to connect the second driving module 306 with all the second sub laser providing modules 3082, and controls the optical fiber coupler 312 to select the second laser output by all the second sub laser providing modules 3082.
When the detection result signal is not received or a normal detection result signal is received, it indicates that the first sub-laser providing module 3081 works normally, and at this time, the control module 302 may control the first driving module 304 to be electrically connected to the first sub-laser providing module 3081, and control the optical fiber coupler 312 to select the first laser output by the first sub-laser providing module 3081.
The first sub laser providing module 3081 and the second sub laser providing module 3082 are used for converting electric energy into laser, and outputting the laser to an incident end face of the optical fiber after operations such as dodging and converging. In this embodiment, the first sub laser light providing module 3081 and the second sub laser light providing module 3082 may include a laser, a light uniformizing member, a converging optical element, and the like. The laser is used for generating laser, the dodging component is used for dodging the laser, and the converging optical element converges the dodged laser and outputs the converged laser to the incident end face of the optical fiber. The laser beams generated by the first sub laser beam supply module 3081 and the second sub laser beam supply module 3082 are transmitted through the optical fiber and then emitted from the emission end face of the optical fiber.
The light emitting unit 320 outputs laser light or converts the laser light and outputs the converted laser light. In one mode, the light emitting section 320 outputs laser light. In another embodiment, the light emitting part 320 may include a wavelength conversion material that absorbs the laser light and generates a stimulated light having a wavelength different from the laser light, and outputs the stimulated light; or the wavelength conversion material absorbs part of the exciting light and converts the exciting light into stimulated light, and outputs mixed light of the exciting light and the stimulated light.
In addition, the light emitting portion 320 may further include some optical elements, such as a lens assembly, for guiding, converging, diverging, homogenizing, etc. the laser light emitted from the light emitting end face of the optical fiber.
In other embodiments, the detecting module 310 can also detect the operating status of the first driving module 304; when the working state of the first driving module 304 is abnormal, the detecting module 310 outputs the abnormal detection result signal, at this time, the control module 302 may select the second driving module 306 to provide power for the second sub laser providing module 3082, and the control module 302 further controls the optical fiber coupler 312 to select the second laser output by the second sub laser providing module 3082. Thus, when the first sub-laser providing module 3081 works abnormally, the electrical connection between the first sub-laser providing module 3081 and the first driving module 304 can be closed, which is beneficial to reducing the power consumption of the system.
According to the laser fiber lighting system, the working state of the first sub-laser providing module is detected, and when the working state of the first sub-laser providing module is abnormal, the standby sub-laser providing module is switched to continue outputting laser, so that the stability of the system is improved.

Compared to the third preferred embodiment, the first sub-laser providing module 3081 and the second sub-laser providing module 3082 are both powered by the third driving module 314. The detection module 310 may detect the operating state of the first sub-laser providing module 3081 and output a detection result signal. When the detection result signal is not received or a normal detection result signal is received, it indicates that the first sub-laser providing module 3081 works normally, and at this time, the control module 302 may control the third driving module 314 to be turned on by the first sub-laser providing module 3081, and control the optical fiber coupler 312 to select the first laser output by the first sub-laser providing module 3081; when the working state of the first sub-laser providing module 3081 is abnormal, the detecting module 310 may output an abnormal detection result signal to the control module 302, and the control module 302 may control the third driving module 314 to be conducted with a part of the second sub-laser providing modules 3082, and the optical fiber coupler 312 selects output light of the first sub-laser providing module 3081 and a part of the second sub-laser 3082, or cuts off an electrical connection between the third driving module 314 and the first sub-laser providing module 3081, conducts an electrical connection between the third driving module 314 and all the second sub-laser providing modules 3082, and controls the optical fiber coupler 312 to select laser output by all the second sub-laser providing modules 3082.
Specifically, when the abnormality detection result signal indicates that the first laser light provided by the first sub-laser light providing module 3081 does not meet the predetermined requirement, the control module 302 conducts the electrical connection between the third driving module 314 and the first sub-laser light providing module and a part of the second sub-laser light providing module 3082, and controls the fiber coupler 312 to select a part of the second laser light output by the second sub-laser light providing module 3082 and a part of the first laser light output by the first sub-laser light providing module 3081, so as to enhance the brightness of the first laser light by the part of the second laser light, thereby meeting the predetermined requirement; when the abnormality detection result signal indicates that the first sub laser providing module cannot provide the first laser, the control module 302 controls to cut off the electrical connection between the third driving module 314 and the first sub laser providing module 3081, and to conduct the electrical connection between the third driving module 314 and all the second sub laser providing modules, and controls the optical fiber coupler 312 to select the laser output by the first sub laser providing module 3081. The connection relationship and functions of other elements in this embodiment are the same as those in the third preferred embodiment, and therefore, the description thereof is omitted.
It can be understood that, when the first sub laser providing module 3081 is in the normal operation state, the second sub laser module 3082 is in the standby state, i.e. is not conducted with the driving module; when the first sub laser module 3081 cannot work normally, the electric connection between the first sub laser module 3081 and the driving module is cut off, so that the purpose of saving the energy consumption of the system is achieved.
According to the laser fiber lighting system, the working state of the first sub-laser providing module is detected, and when the working state of the first sub-laser providing module is abnormal, the standby sub-laser providing module is switched to continue outputting laser, so that the stability of the system is improved.
