Description

Technical Field

[0001] This invention relates to the field of laser lighting technology, and in particular to a safety protection system for laser equipment and a laser street light. Background Technology

[0002] Laser technology, due to its superior characteristics such as high brightness, high directionality, and high energy density, has been widely used in many fields, including industrial processing, medical aesthetics, communication displays, and lighting. Laser equipment typically includes a laser source, optical system, power supply and control module, and supporting components (such as housing, brackets, and bases). Reliable connections between these components and the physical integrity of the equipment are fundamental to ensuring safe laser emission and preventing unintended radiation.

[0003] However, existing laser equipment still suffers from widespread safety deficiencies. Many devices focus on monitoring laser output power, operating temperature, or circuit status, but lack effective, real-time monitoring of the equipment's own physical structural integrity. When critical mechanical connections (such as housing openings, module mounting interfaces, and support structure connection points) become loose, separate, or damaged due to accidental impacts, aging, human intervention, or natural disasters (such as earthquakes or floods), the laser source may still be operating, posing a risk of accidental laser leakage or altered radiation path, and potentially threatening operators, surrounding equipment, or the environment. This is especially true in scenarios requiring on-site installation, regular maintenance, or component replacement, where the operation itself may involve disassembling these mechanical connections. Existing technologies largely rely on standardized personnel operation and subsequent inspections, lacking an active, rigid safety interlock mechanism that automatically and forcibly cuts off the laser power supply when structural connections are interrupted. This introduces additional safety hazards for installation and maintenance personnel.

[0004] Furthermore, if physical wiring is introduced to monitor connection status, using conventional conductors, due to their strong mechanical properties, may result in low electrical continuity even during structural deformation or partial separation, leading to low protection sensitivity and unreliable triggering of protection actions, thus causing the safety protection mechanism to fail. If the layout of the protection wiring is too complex, it will interfere with the normal assembly of the equipment, increasing the difficulty of installation and maintenance. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a safety protection system for laser equipment and a laser street light to solve one of the problems of existing laser equipment lacking safety protection, having complex safety protection structures, and having insufficient protection sensitivity.

[0006] On one hand, embodiments of the present invention provide a safety protection system for laser equipment, including a first protective base, a safety switch and a breakable monitoring wire, wherein the first protective base, the safety switch and the breakable monitoring wire are connected in series to form a safety monitoring circuit; It also includes a laser module and a laser power controller. The safety switch is used to control the laser power controller and the laser module to be powered on or off. When powered on, the laser power controller is used to control the laser module to be turned on or off.

[0007] Furthermore, the first protective seat includes a first retaining ring and a second retaining ring, which are fixedly connected and connected by positive and negative terminals.

[0008] Furthermore, the first retaining ring includes a first positive terminal and a first negative terminal, and the second retaining ring includes a second positive terminal and a second negative terminal; the first positive terminal and the second positive terminal are in contact and connected, and the first negative terminal and the second negative terminal are in contact and connected.

[0009] Furthermore, the first positive terminal is connected to the positive terminal of the safety switch, the first negative terminal is connected to the negative terminal of the safety switch, and the second positive terminal and the second negative terminal are connected by a breakable monitoring wire.

[0010] Furthermore, the first retaining ring also includes a first retaining ring body, and the second retaining ring also includes a second retaining ring body.

[0011] Furthermore, the first positive electrode contact and the first negative electrode contact are disposed on the first retaining ring body, and the second positive electrode contact and the second negative electrode contact are disposed on the second retaining ring body.

[0012] Furthermore, the positions of the first positive electrode contact and the second positive electrode contact correspond to each other, and the positions of the first negative electrode contact and the second negative electrode contact correspond to each other.

[0013] Furthermore, both the first retaining ring body and the second retaining ring body are provided with connecting lugs, and the connecting lugs are provided with connecting holes. The locking member passes through the connecting holes to achieve a fixed connection between the first retaining ring and the second retaining ring.

[0014] Furthermore, the breakage monitoring wire is an ultra-fine copper wire, and the diameter of the breakage monitoring wire is 0.1-0.5 mm.

[0015] On the other hand, embodiments of the present invention provide a laser street light, including a safety protection system for the laser device as described above.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. The safety protection system for laser equipment in this invention comprises a first protective base, a safety switch, and a breakable monitoring wire connected in series to form a safety monitoring circuit, enabling safety monitoring and protection of the laser equipment. The safety switch controls the power supply to and from the laser module and laser power controller. When the safety monitoring circuit is connected, the safety switch powers on the laser module and laser power controller, which in turn controls the laser module's on / off state. When the safety monitoring circuit is disconnected, the safety switch de-energizes the laser module and laser power controller, preventing them from emitting laser light. In the event of external force damage, the breakable monitoring wire will disconnect under the force, promptly cutting off the safety monitoring circuit, triggering safety protection, and improving the safety of the laser equipment and the sensitivity of the safety protection system.

[0017] 2. The safety protection system for the laser equipment in this invention includes a first protective base comprising a first retaining ring and a second retaining ring connected to each other, with the first and second retaining rings connected by positive and negative contacts. When the laser equipment is damaged by external force, causing the connection between the first and second retaining rings to break and / or the easily broken monitoring wire to break, the safety monitoring circuit formed by the first protective base, the safety switch, and the easily broken monitoring wire breaks. The safety switch controls the laser power controller and the laser module to de-energize and stop working, and the laser module stops emitting laser light, preventing the laser light emitted by the laser module from leaking into the environment when the laser equipment is not installed properly or is damaged, thus improving the safety of the laser equipment. Furthermore, the first protective base and the easily broken monitoring wire are connected in series to jointly participate in the safety protection, improving the sensitivity and reliability of the safety protection system. The structure and connection method of the first retaining ring, the second retaining ring, and the easily broken monitoring wire are simple, occupy little space, do not require significant modifications to the original structure of the laser equipment, and are easy to arrange within the laser equipment.

[0018] 3. The safety protection system for laser equipment in this invention uses ultra-fine copper wire as the easily breakable monitoring lead, which is easily broken. When the easily breakable monitoring lead is damaged by external force, the ultra-fine copper wire is easily torn off, improving the sensitivity of the safety protection system. The ultra-fine copper wire is easy to arrange in the laser equipment, occupies little space, does not affect the structure and appearance of the laser equipment, and is easy to maintain.

[0019] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention.

Detailed Implementation

[0022] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0023] Example 1 To address the issues of insufficient safety protection and inadequate protection sensitivity in laser equipment, a specific embodiment of the present invention discloses a safety protection system for laser equipment, such as... Figure 1As shown, it includes a first protective base 1, a safety switch 2, and a breakable monitoring wire 3. The first protective base 1, the safety switch 2, and the breakable monitoring wire 3 are connected in series to form a safety monitoring circuit, realizing the safety monitoring and protection of the laser equipment.

[0024] It also includes a laser module 100 and a laser power controller 101. Safety switch 2 controls the power supply to and from the laser module 100 via the laser power controller 101. When powered on, the laser power controller 101 controls the laser module 100 to turn on and off. When the safety monitoring circuit is connected, safety switch 2 controls the laser power controller 101 to power on and off the laser module 100. When the safety monitoring circuit is disconnected, safety switch 2 controls the laser power controller 101 to de-energize and stop working on the laser module 100. When the laser equipment is damaged by external force, the easily broken monitoring wire 3 will break under the force, promptly cutting off the safety monitoring circuit, triggering safety protection, de-energizing and shutting down the laser module 100, stopping laser emission, preventing laser leakage, and improving the safety of the laser equipment and the sensitivity of the safety protection system.

[0025] Furthermore, to address the issue of complex safety protection structures, such as Figure 1 and Figure 2 As shown, the first protective seat 1 includes a first retaining ring 11 and a second retaining ring 12. The first retaining ring 11 and the second retaining ring 12 are fixedly connected, and the first retaining ring 11 and the second retaining ring 12 are in contact and connected through positive and negative terminals.

[0026] Specifically, such as Figure 2 As shown, the first retaining ring 11 includes a first positive terminal 111 and a first negative terminal 112, and the second retaining ring 12 includes a second positive terminal 121 and a second negative terminal 122; the first positive terminal 111 and the second positive terminal 121 are in contact and connected, and the first negative terminal 112 and the second negative terminal 122 are in contact and connected.

[0027] The first positive terminal 111 of the first retaining ring 11 is connected to the positive terminal E+ of the safety switch 2, the first negative terminal 112 of the first retaining ring 11 is connected to the negative terminal E- of the safety switch 2, and the second positive terminal 121 and the second negative terminal 122 of the second retaining ring 12 are connected by a breakable monitoring wire 3.

[0028] Specifically, the first positive terminal 111 and the positive terminal E+ of the safety switch 2 are connected by a common wire, and the first negative terminal 112 and the negative terminal E- of the safety switch 2 are connected by a common wire.

[0029] When the laser equipment is damaged by external force, causing the connection between the first retaining ring 11 and the second retaining ring 12 to break and / or the easily broken monitoring wire 3 to break, the safety monitoring circuit formed by the connection of the first protective seat 1, the safety switch 2, and the easily broken monitoring wire 3 will break. The safety switch 2 will control the laser module 100 to disconnect from the laser power controller 101, preventing the laser module 100 from emitting laser light. This prevents the laser emitted by the laser module 100 from leaking into the environment when the laser equipment is not installed properly or is damaged, thus improving the safety of the laser equipment. Furthermore, the first protective seat 1 and the easily broken monitoring wire 3 are connected in series to jointly participate in safety protection, improving the sensitivity and reliability of the safety protection system. In addition, the structure and connection method of the first retaining ring 11, the second retaining ring 12, and the easily broken monitoring wire 3 are simple, occupy little space, and do not require significant modifications to the original structure of the laser equipment, making them easy to arrange within the laser equipment.

[0030] Furthermore, to address the problem of insufficient protective capabilities, such as Figure 1 As shown, the safety protection system of the laser equipment also includes a second protective seat 4. The first protective seat 1, the safety switch 2, the second protective seat 4 and the easily broken monitoring wire 3 are connected in series to form a safety monitoring circuit. The first protective seat 1 and the second protective seat 4 are used to perform safety monitoring and protection on different positions of the laser equipment, thereby improving the reliability and protection capability of the safety protection.

[0031] The second protective seat 4 includes a third retaining ring 41 and a fourth retaining ring 42, which are fixedly connected and connected by positive and negative terminals.

[0032] Specifically, such as Figure 3 As shown, the third retaining ring 41 includes a third positive terminal 411 and a third negative terminal 412, and the fourth retaining ring 42 includes a fourth positive terminal 421 and a fourth negative terminal 422. The third positive terminal 411 and the fourth positive terminal 421 are in contact and connected, and the third negative terminal 412 and the fourth negative terminal 422 are in contact and connected.

[0033] Furthermore, to address the issue of insufficient sensitivity in security protection, such as Figure 1As shown, the easily broken monitoring wire 3 includes a first wire 31, a second wire 32, and a third wire 33. The two ends of the first wire 31 are connected to the second positive terminal 121 of the second retaining ring 12 and the third positive terminal 411 of the third retaining ring 41, respectively. The two ends of the second wire 32 are connected to the second negative terminal 122 of the second retaining ring 12 and the third negative terminal 412 of the third retaining ring 41, respectively. The two ends of the third wire 33 are connected to the fourth positive terminal 421 and the fourth negative terminal 422 of the fourth retaining ring 42, respectively. The first wire 31, the second wire 32, and the third wire 33 are arranged inside the laser equipment. When the laser equipment is damaged, the first wire 31, the second wire 32, and / or the third wire 33 inside the laser equipment will break under force, promptly cutting off the safety monitoring circuit and improving the sensitivity of the safety protection system.

[0034] For example, the easily broken monitoring wire 3 is an ultra-fine copper wire with a sheath. The diameter of the easily broken monitoring wire 3 is 0.1-0.5 mm, and it has the characteristic of being easily broken. The sheath of the ultra-fine copper wire is made of a brittle material and also has the characteristic of being easily broken. When the easily broken monitoring wire 3 is damaged by external force, the sheath and the ultra-fine copper wire will be torn apart. The ultra-fine copper wire is easy to arrange in laser equipment, occupies little space, does not affect the structure and appearance of the laser equipment, and is easy to maintain. The sheath protects the ultra-fine copper wire and prevents leakage.

[0035] Furthermore, to address the issue of low connection stability of the protective seat, such as... Figure 2 As shown, the first retaining ring 11 also includes a first retaining ring body 110, and the second retaining ring 12 also includes a second retaining ring body 120. The first positive electrode contact 111 and the first negative electrode contact 112 are disposed on the side of the first retaining ring body 110 near the second retaining ring 12, and the second positive electrode contact 121 and the second negative electrode contact 122 are disposed on the side of the second retaining ring body 120 near the first retaining ring 11. The positions of the first positive electrode contact 111 and the second positive electrode contact 121 are corresponding, and the positions of the first negative electrode contact 112 and the second negative electrode contact 122 are corresponding. Both the first retaining ring body 110 and the second retaining ring body 120 are provided with connecting lugs 13, and the connecting lugs 13 are provided with connecting holes 131. The locking member passes through the connecting holes 131 to realize the fixed connection between the first retaining ring 11 and the second retaining ring 12, and to make the first positive terminal contact 111 and the second positive terminal contact 121, and the first negative terminal contact 112 and the second negative terminal contact 122 in stable contact, so as to realize the stable connection of the protective seat.

[0036] For example, the connecting hole is a threaded hole, and the locking element is a bolt and a nut.

[0037] The structure of the second protective seat 4 is the same as that of the first protective seat 1, and will not be described again here.

[0038] Furthermore, to address the issue of low control stability of safety switch 2, such as... Figure 4As shown, safety switch 2 is an electromagnetic relay switch, including an electromagnetic device and a normally open contact. The positive terminal E+ and negative terminal E- of the electromagnetic device are respectively connected to the first positive terminal contact 111 and the first negative terminal contact 112 of the first retaining ring 11. The electromagnetic device of safety switch 2, the first protective base 1, the easily broken monitoring wire 3, and the external AC power supply are connected in series to form a safety monitoring circuit, realizing the safety monitoring and protection of the laser equipment. An AC / DC rectifier is also connected between the electromagnetic device of safety switch 2 and the external AC power supply. The normally open contact of safety switch 2, the laser module 100, the laser power controller 101, and the external AC power supply are connected in series to form the laser source power supply circuit. The safety monitoring circuit and the laser source power supply circuit share the same external AC power supply, and the safety monitoring circuit and the laser source power supply circuit are connected in parallel on the external AC power supply. The safety switch 2 realizes the power-off protection of the laser source power supply circuit. Under normal operating conditions, the safety monitoring circuit of the safety protection system is connected, the normally open contact of safety switch 2 is closed, and the laser source power supply circuit is connected. The laser module 100 is controlled to turn on and off via the laser power controller 101. When the laser equipment is damaged or needs to be disassembled for maintenance, the connection between the first retaining ring 11 and the second retaining ring 12 of the safety protection system is disconnected, and / or the connection between the third retaining ring 41 and the fourth retaining ring 42 is disconnected, and / or the easily broken monitoring wire 3 is disconnected. The safety monitoring circuit of the safety protection system is disconnected, the electromagnetic device of safety switch 2 is de-energized, and the electromagnetic device mechanically drives the normally open contact to open, thereby cutting off the laser source power supply circuit. The laser module 100 is de-energized and shut down to prevent laser leakage. The coil of safety switch 2 is connected in series in the safety monitoring circuit, and the normally open contact of safety switch 2 is connected in series in the laser source power supply circuit. The connection between the safety monitoring circuit and the laser source power supply circuit is achieved mechanically, ensuring stable and reliable control.

[0039] Example 2 To address the issue of low safety in laser streetlights, one specific embodiment of the present invention, based on Embodiment 1, discloses a laser streetlight, such as... Figure 5 As shown, the safety protection system for the laser equipment in Embodiment 1 also includes a mounting base 5, a lamp post 6, and a lamp head 7. The lamp post 6 is mounted on the mounting base 5. A first protective seat 1 is located at the connection between the lamp post 6 and the mounting base 5. A first retaining ring 11 and a safety switch 2 are located inside the mounting base 5. A second retaining ring 12 is located at the bottom inner side of the lamp post 6. A second protective seat 4 is located at the connection between the lamp post 6 and the lamp head 7. A third retaining ring 41 is fixedly connected to the top of the lamp post 6, and a fourth retaining ring 42 is fixedly connected to the lamp head 7.

[0040] During installation, the lamp post 6 is mounted on the mounting base 5, connecting the first retaining ring 11 and the second retaining ring 12, and ensuring that the first positive terminal 111 and the second positive terminal 121 are in contact and connected, as are the first negative terminal 112 and the second negative terminal 122. The lamp head 7 is then connected to the lamp post 6, connecting the third retaining ring 41 and the fourth retaining ring 42, and ensuring that the third positive terminal 411 and the fourth positive terminal 421 are in contact and connected, as are the third negative terminal 412 and the fourth negative terminal 422. At this point, the safety monitoring circuit is activated. The first conductor 31 and the second conductor 32 are arranged along both sides of the lamp post 6, and the third conductor 33 is arranged inside the lamp head 7. When the lamp post 6 of the laser street light is damaged, the first conductor 31 and / or the second conductor 32 disconnect; when the lamp head 7 of the laser street light is damaged, the third conductor 33 disconnects, thus promptly shutting down the laser module 100, preventing the laser emitted by the laser module 100 from leaking into the environment, and improving the safety protection performance of the laser street light.

[0041] Furthermore, the laser module 100 and the laser power controller 101 are installed inside the lamp post 6, which is a hollow rod-shaped structure. The first retaining ring 11, the second retaining ring 12, the third retaining ring 41 and the fourth retaining ring 42 are all provided with a central opening to provide a path for the laser to pass through.

[0042] Furthermore, such as Figure 6 As shown, the laser street light also includes a lampshade 8, which is connected to the lamp head 7. The lampshade 8 is used to emit the illumination light excited by the laser into the environment. A third conductor 33 is wound and arranged inside the lampshade 8 for safety monitoring of the lampshade 8. Specifically, as... Figure 4 As shown, the third wire 33 in the lamp cover 8 is wound in a serpentine or spiral shape. When the lamp cover 8 is damaged, the third wire 33 is disconnected, and the laser module 100 is shut down under the control of the safety switch 2 to prevent the laser from leaking from the damaged part of the lamp cover 8 and improve the safety protection performance of the laser street light.

[0043] In this embodiment, the laser street light controls the power supply and de-energization of the laser module 100 and the laser power controller 101 via a safety switch 2. When the connection between the first retaining ring 11 and the second retaining ring 12 is disconnected, or the connection between the third retaining ring 41 and the fourth retaining ring 42 is disconnected, or the easily broken monitoring wire 3 is disconnected, the safety monitoring circuit is disconnected, and the safety switch 2 controls the laser module 100 and the laser power controller 101 to de-energize, thus disconnecting the laser source power supply circuit. The laser module 100 cannot emit laser light, preventing the laser emitted by the laser module 100 from leaking into the environment when the laser street light is not installed properly, the lamp post 6 falls down as a whole, the lamp post 6 is damaged, or the lamp head 7 is damaged, thereby improving the safety of the laser street light. The first protective seat 1 is installed at the connection between the lamp post 6 and the mounting base 5, and the second protective seat 4 is installed at the connection between the lamp post 6 and the lamp head 7. These locations respectively monitor the safety of the mounting points of the lamp post 6 and the lamp head 7. If the laser street light is damaged by external force or a natural disaster, causing the lamp post 6 to collapse or the lamp head 7 to detach, the connection between the first retaining ring 11 and the second retaining ring 12 of the first protective seat 1 will break, or the connection between the third retaining ring 41 and the fourth retaining ring 42 of the second protective seat 4 will break. This triggers the safety protection mechanism, and the safety switch 2 controls the laser module 100 to shut down, thus monitoring the overall structure of the laser street light. Furthermore, easily broken monitoring wires 3 are arranged inside the lamp post 6, the lamp head 7, and the lamp cover 8 to perform localized safety monitoring of the laser street light structure, improving the comprehensiveness of the laser street light's safety protection.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
