Description

Technical Field

[0001] This invention relates to the field of lighting overload protection technology, specifically to an emergency overload protection device for high-power LED lighting fixtures. Background Technology

[0002] High-power LED lights can be damaged by circuit overload or overcurrent, even posing safety hazards. Overload emergency protection devices can monitor the current and cut off the power supply in time when the current exceeds a set threshold, preventing damage to the LED lights. By cutting off the power supply in time, overload emergency protection devices can prevent LED lights from operating in an overload state for a long time, thereby effectively preventing safety accidents such as fires and electric shocks caused by circuit overload, and protecting personal and property safety.

[0003] The invention, with publication number CN114284996A and titled "A Protective Device for Abnormal Overheating of a Conductor," states: "This protective device for abnormal overheating of a conductor, through the coordinated use of a metal spring, a supporting spring, a first contact, a second contact, and an alarm, when a short circuit or overload occurs in the conductor, causing excessive current, the metal spring overcomes the supporting force of the supporting spring and deflects upward. The left side of the metal spring moves to the top of the supporting spring, at which point the first contact separates from the second contact, automatically cutting off the circuit. At this time, the alarm sounds, thus achieving the effect of automatically cutting off the circuit in the event of conductor overheating and improving the safety of the circuit."

[0004] Since high-power LED lights are generally composed of multiple small lights, and most high-power LED lights use a parallel circuit design, each small light has an independent circuit path connected to the power supply. Therefore, the failure of a single light will not affect the operation of other light groups. Compared with the existing technology where a short circuit or overload in the wire causes excessive current, the mechanism is directly triggered to automatically cut off the line. This method will directly cause the equipment to stop working, and subsequent repairs or replacement of damaged parts will require additional time and costs. Especially for lights composed of multiple small lights, the overall equipment is in a more complex or densely wired environment, making repairs more difficult.

[0005] Compared to existing technologies that rely on workers to manually tighten multiple light bulbs, manually installing multiple light bulbs requires installing each bulb into the light fixture one by one, which requires more time and labor. This is especially true for large light fixtures or places where work at heights is required, where the installation complexity is even higher. Furthermore, manually installing multiple light bulbs can lead to inconsistent installation positions and angles, resulting in uneven lighting and affecting the lighting effect. In addition, manual installation may not be able to ensure that each bulb is positioned to achieve the best lighting effect.

[0006] Therefore, in view of this, the present invention proposes an overload emergency protection device for high-power LED lamps to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides an overload emergency protection device for high-power LED lamps, thereby resolving the technical issues raised in the background section.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an overload emergency protection device for high-power LED lamps, including a lamp frame, a mounting base fixedly connected to the top of the lamp frame, a driving power supply installed below the mounting base, connecting wires symmetrically connected to both sides of the driving power supply, and elastic overload protection mechanisms symmetrically arranged on the left and right sides of the lamp frame, each of the elastic overload protection mechanisms having an integrated ventilation and early warning mechanism inside.

[0009] The elastic overload protection mechanism is used to protect the circuit from overload by driving the elastic force to separate the connecting wires from the lamp assembly in time.

[0010] The integrated ventilation and early warning mechanism is used to automatically ventilate and cool the lamp assembly after it is separated.

[0011] Furthermore, the elastic overload protection mechanism includes an assembly cylinder symmetrically and fixedly connected to the inner wall of the lamp holder. A power-conducting plate is rotatably connected to the top of the assembly cylinder. An adapter seat is rotatably connected to the lower surface of the power-conducting plate. A connecting spring is fixedly connected to the inner wall of each adapter seat. A connecting shaft is installed below each adapter seat. Semi-circular grooves are formed on both sides of the connecting shaft. A through groove is formed on the inner wall of the connecting shaft. An elastic ball is fixedly connected inside the through groove. An assembly cylinder is fixedly connected to the lower surface of each elastic ball. Iron ring isolation rods are symmetrically and slidably connected to the upper side wall of the assembly cylinder. A return spring is sleeved on the outer wall of each iron ring isolation rod. A solenoid plate is symmetrically and fixedly connected to the upper surface of the assembly cylinder.

[0012] Furthermore, the outer wall of the assembly cylinder is uniformly provided with a combination groove, the inner side wall of the adapter is fixedly connected with a cylindrical sleeve, and a conductive rod is fixedly connected to the connecting shaft at the position corresponding to the cylindrical hole. The adapter and the connecting shaft are slidably connected through the cylindrical hole and the conductive rod.

[0013] Furthermore, the elastic ball is composed of a metal sphere and a polymer plate, and the installation position of the metal sphere in the elastic ball corresponds to the semi-circular groove.

[0014] Furthermore, the energizing board is electrically connected to the connecting wire, the energizing board is initially perpendicular to the electromagnetic plate, the iron ring isolation rod is set as a circular iron ring on the side near the electromagnetic plate, and the two ends of the reset spring are fixedly connected to the iron ring isolation rod and the assembly cylinder, respectively.

[0015] Furthermore, the end of the iron ring isolation rod away from the electromagnetic plate corresponds to the semi-circular groove, and the end of the iron ring isolation rod near the semi-circular groove is set in a triangular inclined shape. The connecting shaft and the iron ring isolation rod are inserted into each other through the semi-circular groove.

[0016] Furthermore, the end of the connecting tube furthest from the elastic ball is fixedly connected to the light bulb.

[0017] Furthermore, the inner cavity bottom wall of the assembly cylinder is uniformly slidably connected with a sliding shaft abutment pad, and upper hinge groups are symmetrically hinged on the left and right sides of the sliding shaft abutment pad. An isolation plate is hinged to the end of the upper hinge group away from the sliding shaft abutment pad, and a lower hinge group is hinged to the outer wall of the isolation plate. A fixed base plate is fixedly connected to the end of the lower hinge group away from the isolation plate, and the fixed base plate maintains a slidable connection with the sliding shaft abutment pad.

[0018] Furthermore, the sliding shaft abutment pad is composed of a rubber pad and a sliding shaft. The sliding shaft abutment pad is installed directly below the light bulb, and the size of the rubber pad in the sliding shaft abutment pad is adapted to the overall size of the connecting wire.

[0019] Furthermore, the overall shape of the isolation plate is arc-shaped, and the isolation plate is initially in a fitted state with the assembly cylinder through the combination groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) This device ejects the bulb by triggering the connecting spring. This ejection separation method separates the faulty component from the circuit, which can avoid the problem of arcing, sparking or short circuit caused by directly cutting off the line and suddenly cutting off the power. This reduces the risk of fire or safety accidents. As can be seen from the steps of installing the bulb mentioned in the working principle section, compared with the traditional screw rotation method of installing the bulb, this device greatly simplifies the bulb installation process. Since the bulb and the mounting base are connected by a cylindrical conductive rod, and cylindrical structural components are usually simple to design and easy to use, they can quickly complete the connection and disassembly of equipment or parts. In addition, during multiple disassembly and installation, the friction between the components can be greatly reduced, thereby improving the stability of the equipment connection. At the same time, it can ensure that the overall lamp is suitable for various types of bulbs, thereby improving the flexibility of lamp installation.

[0022] During the bulb installation process, the metal sphere, after being struck by the triangular inclined block, repeatedly oscillates and collides with the triangular inclined block due to the elasticity of the polymer plate itself, thus producing a continuous knocking sound. The worker can use this knocking sound to determine whether the bulb is installed correctly. This device uses the knocking sound to prompt the worker to check whether the bulb is installed correctly, which can avoid problems such as unstable or malfunctioning bulbs caused by manual installation due to loose installation. At the same time, it can also reduce the contact friction between the bulb and the mounting base, avoiding wear and damage to the bulb connection parts caused by excessive force by the worker, thereby extending the bulb's service life.

[0023] (2) The assembly tube in this device can ensure that the bulb achieves a sealed protection function during normal illumination, preventing the bulb's outer wall from being dirtyed by mosquitoes and keeping the lamp clean and tidy. At the same time, using the assembly tube to seal the lamp assembly can make the lamp as a whole. In addition, the assembly tube is designed to be made of mirror material and the assembly tube is wider at the bottom and narrower at the top. Because the lower part of the assembly tube is wider, the center of gravity of the assembly tube itself is relatively low, which makes the narrow part at the top of the assembly tube more stable and less prone to tilting or imbalance. This can effectively reduce the risk of accidental tipping or sliding. When the bulb is in normal illumination, the assembly tube can concentrate and reflect the light to the wider part of the assembly tube, ensuring that the light is evenly dispersed and distributed more evenly in the environment, thereby enhancing the overall lighting effect. At the same time, by relying on the combination of the assembly tube reflecting light, the limitations of light illumination caused by the sealing of the assembly tube can be solved.

[0024] (3) This device, through the unfolded form after the assembly cylinder is separated, can directly remind the staff of the specific location of the bulb, reducing omissions and errors caused by visual inspection and improving the accuracy of inspection. At the same time, it prepares for the staff to correct wiring problems, so that the staff can replace or repair the bulb in a targeted manner without additional searching and confirmation steps. For existing technology lamps composed of multiple small lights, and for scenarios where the overall equipment is in a complex and dense wiring environment, this device, by separating the isolation plate and the assembly cylinder in an alternating manner, makes it convenient for the staff to directly remove the bulb inside the assembly cylinder. At the same time, the bulb can be directly placed into the assembly cylinder through the combination slot. Then, following the steps of pushing the bulb upward as mentioned in the working principle, the bulb can be removed. The process involves three steps: removal, replacement, and installation. Furthermore, because the isolation plates are symmetrically distributed on both sides of the assembly cylinder, maintaining a separate and staggered state with the assembly cylinder effectively increases the ventilation area between the inside of the assembly cylinder and the external environment. Additionally, the arc-shaped design of the assembly groove reduces or eliminates dead angles around the isolation plates during gas flow, preventing subsequent isolation plates from obstructing gas flow. Therefore, this method significantly accelerates airflow and effectively removes heat from around the bulb. Compared to existing technologies that rely on additional cooling devices such as heat sinks, heat pipes, or coolant to accelerate bulb heat dissipation, this device's heat dissipation and ventilation method reduces the complexity of adding additional cooling devices, avoiding the need for more components and system designs that would increase the difficulty of subsequent manufacturing and maintenance.

[0025] When the bulb is ejected, the sliding shaft abutment pad protects the separated bulb, preventing damage from collisions. Since the size of the rubber pad in the sliding shaft abutment pad matches the overall size of the connecting wire, it can further limit the bulb's position after separation, making the bulb's position more precise and preventing it from being difficult to remove due to changes in its own position.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Embodiments of the present invention

[0038] Please refer to Figure 1 As shown, a high-power LED lamp overload emergency protection device includes a lamp holder 1, a mounting base 11 fixedly connected to the top of the lamp holder 1, a driving power supply 12 installed below the mounting base 11, connecting wires 13 symmetrically connected to both sides of the driving power supply 12, and elastic overload protection mechanisms 2 symmetrically arranged on the left and right sides of the lamp holder 1. Each elastic overload protection mechanism 2 is equipped with a ventilation and early warning integrated mechanism 3 inside.

[0039] The elastic overload protection mechanism 2 is used to protect the circuit from overload by driving the elastic force to separate the connecting wire 13 from the lamp assembly in time.

[0040] The integrated ventilation and early warning mechanism 3 is used to automatically ventilate and cool the lamp assembly after it is separated.

[0041] Please refer to Figure 2 - Figure 4 As shown, the elastic overload protection mechanism 2 includes an assembly cylinder 21 symmetrically fixedly connected to the inner wall of the lamp holder 1. A power-conducting plate 22 is rotatably connected to the top of the assembly cylinder 21. An adapter seat 23 is rotatably connected to the lower surface of the power-conducting plate 22. A connecting spring 24 is fixedly connected to the inner wall of each adapter seat 23. A connecting shaft 25 is installed below each adapter seat 23. Semi-circular grooves 26 are provided on both the left and right sides of the connecting shaft 25. A through groove 27 is provided on the inner wall of each connecting shaft 25. An elastic ball 28 is fixedly connected inside the through groove 27. An assembly cylinder 29 is fixedly connected to the lower surface of each elastic ball 28. Iron ring isolation rods 210 are symmetrically slidably connected to the upper side wall of the assembly cylinder 21. Return springs 211 are sleeved on the outer wall of each iron ring isolation rod 210. Electromagnetic plates 212 are symmetrically fixedly connected to the upper surface of the assembly cylinder 21.

[0042] Specifically, in this device, the current exceeds the rated value to drive the energized plate 22 to rotate, directly triggering the iron ring isolation rod 210 to move, causing the triangular inclined block to separate from the semi-circular groove 26. Then, the bulb 14 is ejected and separated by the elastic force of the connecting spring 24 itself. Compared with directly cutting the line, this ejection separation method can reduce the cost and workload of subsequent maintenance or replacement of faulty parts, avoid the sudden power outage caused by direct cutting of the line leading to arc, spark or short circuit problems, reduce the risk of fire or safety accidents, and at the same time, this separation method will not affect the overall lamp assembly, thus ensuring the overall stability of the equipment. In addition, as can be seen from the above steps of installing the bulb 14, when installing the bulb 14, the operator only needs to push it slightly upward to achieve the energization connection between the bulb 14 and the connecting wire 13. Compared with the traditional threaded rotation method of installing the bulb 14, this device greatly simplifies the operation process of installing the bulb 14 and reduces the time required for the operator to replace and disassemble the bulb 14. At the same time, it makes the overall lamp fixture suitable for various types of bulbs 14, including some special shapes or sizes of bulbs 14, thus improving the flexibility of lamp installation.

[0043] Please refer to Figure 3 - Figure 6As shown, the outer wall of the assembly cylinder 21 is uniformly provided with a combination groove 2101. A cylindrical sleeve is fixedly connected to the inner side wall of the adapter seat 23. A conductive rod is fixedly connected to the position of the connecting shaft 25 corresponding to the cylindrical hole. The adapter seat 23 and the connecting shaft 25 are slidably connected to the conductive rod through the cylindrical hole. The elastic ball 28 is composed of a metal ball and a polymer plate. The installation position of the metal ball in the elastic ball 28 corresponds to the semi-circular groove 26. The energizing plate 22 is electrically connected to the connecting wire 13. The energizing plate 22 is initially perpendicular to the energizing plate 212. The side of the iron ring isolation rod 210 near the energizing plate 212 is set as a circular iron ring. The two ends of the return spring 211 are fixedly connected to the iron ring isolation rod 210 and the assembly cylinder 21, respectively.

[0044] Specifically, the triangular inclined block in the iron ring isolation rod 210 collides with the metal ball in the elastic ball 28. Based on the elasticity of the polymer plate itself, the metal ball swings back and forth repeatedly to collide with the triangular inclined block, thus producing a continuous knocking sound. The staff can use this knocking sound to determine whether the bulb 14 is installed in place. Compared with the existing technology that relies on the staff to manually tighten multiple bulbs 14, this device uses the collision contact between the triangular inclined block and the metal ball to produce a knocking sound. The knocking sound can serve as a visual indicator to prompt the staff to determine whether the bulb 14 is installed in place. This can avoid the problem of the bulb 14 being unstable or malfunctioning due to manual installation. At the same time, it can also reduce the contact friction between the bulb 14 and the mounting base 11, avoiding excessive force by the staff to cause wear and damage to the connection parts of the bulb 14, thereby extending the service life of the bulb 14.

[0045] Please refer to Figure 8 - Figure 9 As shown, a sliding shaft abutment pad 31 is uniformly slidably connected to the bottom wall of the inner cavity of the assembly cylinder 21. Upper hinge groups 32 are symmetrically hinged to the left and right sides of the sliding shaft abutment pad 31. An isolation plate 33 is hinged to the end of the upper hinge group 32 away from the sliding shaft abutment pad 31. Lower hinge groups 34 are hinged to the outer side wall of the isolation plate 33. A fixed base plate 35 is fixedly connected to the end of the lower hinge group 34 away from the isolation plate 33. The fixed base plate 35 and the sliding shaft abutment pad 31 are slidably connected. The sliding shaft abutment pad 31 is composed of a rubber pad and a sliding shaft. The sliding shaft abutment pad 31 is installed directly below the bulb 14. The size of the rubber pad in the sliding shaft abutment pad 31 is compatible with the overall size of the connecting wire 13. The overall shape of the isolation plate 33 is arc-shaped. The isolation plate 33 is initially in a close fit with the assembly cylinder 21 through the combination groove 2101.

[0046] Specifically, compared to the existing technology where workers visually inspect each bulb 14, the unfolded form of the assembly cylinder 21 after separation directly indicates the exact location of the bulb 14, reducing omissions and errors caused by visual inspection and improving inspection accuracy. It also prepares the site for subsequent wiring corrections, allowing workers to more easily and specifically replace or repair the bulb 14 without additional searching and confirmation steps, simplifying the maintenance process. Compared to existing technologies for lighting fixtures composed of multiple small bulbs, and in scenarios with complex and dense wiring, the staggered separation between the isolation plate 33 and the assembly cylinder 21 reveals the notch in the assembly groove 2101 on the outer wall of the assembly cylinder 21, making it easy for workers to directly remove the bulb 14 from inside the assembly cylinder 21. Furthermore, when installing a new bulb 14, it can be directly accessed... The bulb 14 is placed into the assembly cylinder 21 through the combination slot 2101. Then, by simply pushing the bulb 14 upward as described above, the three steps of taking out, replacing and installing the bulb 14 can be achieved. In addition, since the isolation plate 33 is symmetrically distributed on both sides of the assembly cylinder 21, when the isolation plate 33 and the assembly cylinder 21 are kept in a separated and staggered state, it is equivalent to increasing the ventilation area between the inside of the assembly cylinder 21 and the external environment. This can not only accelerate the air flow to effectively remove the heat around the bulb 14, but also reduce the damage of excessive temperature to the mounting base 11 and electronic components inside the equipment. Compared with the prior art, which accelerates the heat dissipation of the bulb 14 by adding additional cooling devices, such as heat sinks, heat pipes or coolant, the heat dissipation and ventilation method of this device improves the complexity of adding additional cooling devices and avoids the cooling device involving more components and system design, which would increase the difficulty of subsequent manufacturing and maintenance.

[0047] The following are the complete usage steps and working principle of the above embodiments:

[0048] The elastic overload protection mechanism 2, used to protect the circuit from overload by driving the spring force to promptly separate the connecting wire 13 from the lamp assembly, is specifically used as follows:

[0049] Because the outer wall of the assembly cylinder 21 is uniformly perforated with combination grooves 2101, workers can directly install multiple bulbs 14 into the interior of the assembly cylinder 21 through the combination grooves 2101. Since the bulbs 14 are fixedly connected to the connecting shaft 25 via the assembly cylinder 29, and a cylindrical sleeve is fixedly connected to the inner wall of the adapter 23, and a conductive rod is fixedly connected to the cylindrical hole of the connecting shaft 25, while the adapter 23 and the connecting shaft 25 are slidably connected through the cylindrical hole and the conductive rod, during bulb installation, the connecting shaft 25 can be directly aligned with the cylindrical hole on the inner wall of the adapter 23, and then the bulb 14 can be gradually pushed upwards. Because the outer wall of the connecting shaft 25 is symmetrically provided with semi-circular grooves 26, the end of the iron ring isolation rod 210 away from the electromagnetic plate 212 is connected to the semi-circular groove 26. 6 correspond to each other, and the end of the iron ring isolation rod 210 near the semicircular groove 26 is set as a triangular inclined surface. At the same time, the connecting shaft 25 and the iron ring isolation rod 210 are inserted through the semicircular groove 26. Therefore, when the worker pushes the bulb 14 upward to enter the interior of the adapter 23, the outer wall of the connecting shaft 25 will continuously squeeze the lower inclined surface of the triangular inclined block until the triangular inclined block is completely inserted into the semicircular groove 26. At this time, the worker releases and stops pushing the bulb 14 upward. The bulb 14 itself remains stable and still through the engagement between the semicircular groove 26 and the triangular inclined block. At this time, the bulb 14 has been installed. Since the inner wall of the adapter 23 is fixedly connected to the connecting spring 24, when the bulb 14 moves upward, the connecting shaft 25 will continuously squeeze the connecting spring 24 to make it change to a compressed state.

[0050] When bulb 14 has been used for a long time, the wires inside the bulb assembly may be worn, cut, damaged, or have their insulation damaged. This can cause a short circuit between the wires, causing the current to bypass the predetermined path and exceed the rated value, resulting in a current overload. Since the energizing plate 22 is electrically connected to the connecting wire 13, and the energizing plate 22 is initially perpendicular to the solenoid plate 212, when the above-mentioned current overload occurs, the excessive current passing through the energizing plate 22 will cause the energizing plate 22 itself to be subjected to the force of the magnetic field. According to the principle of Lorentz force, the force on the current carrier in the magnetic field will be perpendicular to the direction of the current and the direction of the magnetic field, and will cause the energizing plate 22 to generate a rotational torque. At this time, the energizing plate 22 will rotate and then keep in contact with the solenoid plate 212 to enter the energized state. Since the iron ring isolation rod 210 is close to the One side of the electromagnetic plate 212 is set with a circular iron ring. Therefore, when the electromagnetic plate 212 is kept energized, the free electrons inside the circular iron ring in the iron ring isolation rod 210 will be affected by the magnetic field generated by the electromagnetic plate 212. As a result, the iron ring isolation rod 210 as a whole will be attracted by the magnetic field of the electromagnetic plate 212. Therefore, the electromagnetic plate 212 will attract the iron ring isolation rod 210 to move along the inner wall of the assembly cylinder 21 towards the electromagnetic plate 212. At this time, the triangular inclined block in the iron ring isolation rod 210 moves out of the semi-circular groove 26, and the clamping force on both sides of the connecting shaft 25 disappears. Therefore, the connecting spring 24, which was in a compressed state inside the energized plate 22, will return to its original state and apply a downward squeezing force to the connecting shaft 25, thereby separating the connecting shaft 25 from the adapter seat 23 and separating the connecting wire 13 from the bulb 14.

[0051] Since high-power LED lights are generally composed of multiple small lights, and most high-power LED lights use a parallel circuit design, each small light has an independent circuit path connected to the power supply. Therefore, the failure of a single light will not affect the operation of other light groups. Compared to the existing technology where a short circuit or overload in the wire causes excessive current, which directly triggers a mechanism to automatically cut off the circuit, causing the equipment to stop working, and requiring additional time and cost for subsequent repairs or replacement of damaged parts, especially for lights composed of multiple small lights, where the overall equipment is in a more complex or densely wired environment, maintenance becomes even more difficult. In contrast, this device uses a current exceeding the rated value to drive the power board 2. 2. Rotation directly triggers the iron ring isolation rod 210 to move it, allowing the triangular inclined block to separate from the semi-circular groove 26. Then, the bulb 14 is ejected and separated by the rebound force of the connecting spring 24 itself. Compared with directly cutting the line, separating the faulty component from the circuit by ejection can reduce the cost and workload of subsequent maintenance or replacement of the faulty component. Moreover, this separation method will not affect the overall lamp assembly, thus ensuring the overall stability of the equipment. In addition, as can be seen from the above steps for installing the bulb 14, when installing the bulb 14, the operator only needs to push it slightly upward to achieve the power connection between the bulb 14 and the connecting wire 13. This device reduces the time required for the operator to replace and disassemble the bulb 14 later.

[0052] like Figure 5 As shown, since the inner wall of the connecting shaft 25 has a through groove 27, and an elastic ball 28 is fixedly connected inside the through groove 27, the elastic ball 28 is composed of a metal ball and a polymer plate. At the same time, the installation position of the metal ball in the elastic ball 28 corresponds to the semi-circular groove 26. Therefore, when the worker pushes the bulb 14 upward, the triangular inclined block in the iron ring isolation rod 210 will move and collide with the metal ball in the elastic ball 28 when it enters the semi-circular groove 26. Since the metal ball is fixedly connected to the through groove 27 through the polymer plate, and the polymer plate has excellent insulation and resilience, the metal ball will swing back and forth by relying on the resilience of the polymer plate itself after being collided, thereby achieving the purpose of colliding with the triangular inclined block multiple times.

[0053] During the installation of bulb 14, the triangular inclined block in the iron ring isolation rod 210 collides with the metal ball in the elastic ball 28. Based on the elasticity of the polymer plate itself, the metal ball swings back and forth and collides with the triangular inclined block multiple times. Compared with the existing technology that relies on workers to manually tighten multiple bulbs 14, this device uses the collision contact between the triangular inclined block and the metal ball to produce a knocking sound, which can avoid the problem of bulb 14 being unstable or malfunctioning due to loose installation caused by manual installation.

[0054] Since multiple bulbs 14 are installed inside the assembly tube 21, the assembly tube 21 can achieve a sealing and protective function during normal use of the bulbs 14, preventing insects such as mosquitoes from rotating around the bulbs 14. At the same time, since the assembly tube 29 is made of mirror material, when the bulbs 14 are in normal operation, the assembly tube 29 can concentrate and reflect the light, ensuring that the light is evenly dispersed and distributed more evenly in the environment, thereby enhancing the overall lighting effect.

[0055] The ventilation and early warning integrated mechanism 3, used to automatically ventilate and cool the lamp assembly after separation, is specifically used as follows:

[0056] like Figures 7 to 8 As shown, since the inner cavity bottom wall of the assembly cylinder 21 is uniformly slidably connected with the sliding shaft abutment pad 31, and the sliding shaft abutment pad 31 is composed of a rubber pad and a sliding shaft, and the sliding shaft abutment pad 31 is installed directly below the bulb 14, when the bulb 14 is ejected due to the current overload, the separated bulb 14 will fall above the rubber pad of the sliding shaft abutment pad 31. The sliding shaft abutment pad 31 protects the separated bulb 14 and prevents damage to the bulb 14 due to collision after separation. Furthermore, since the size of the rubber pad in the sliding shaft abutment pad 31 is compatible with the overall size of the connecting wire 13, the sliding shaft abutment pad 31 can further limit the position of the bulb 14 after separation, making the position of the separated bulb 14 more accurate and preventing the bulb 14 from being difficult to remove due to changes in its own position.

[0057] Since the upper hinge group 32 is symmetrically hinged on the left and right sides of the sliding shaft abutment pad 31, and the upper hinge group 32 is hinged to the isolation plate 33 at the end away from the sliding shaft abutment pad 31, when the bulb 14 falls above the sliding shaft abutment pad 31, it will exert a downward pushing force on the sliding shaft abutment pad 31. At this time, the sliding shaft abutment pad 31 moves slowly downward, thereby squeezing the upper hinge group 32 on both sides, causing the upper hinge group 32 to slowly expand to both sides. Since the outer side wall of the isolation plate 33 is hinged to the lower hinge group 34, during the extension of the upper hinge group 32, it will continuously push the isolation plate 33 on both sides to flip outward under the support of the lower hinge group 34. Since the overall shape of the isolation plate 33 is arc-shaped, and the isolation plate 33 is initially in a close fit with the assembly cylinder 21 through the combination groove 2101, the isolation plate 33 pushed by the upper hinge group 32 will be offset from the assembly cylinder 21 until it separates.

[0058] During the process of the bulb 14 separating and contacting the sliding shaft abutment pad 31, the upper hinge assembly 32 will be subjected to downward squeezing force, which will cause the isolation plate 33 to flip to both sides. At this time, the isolation plate 33, which has been in contact with the assembly cylinder 21, will change to an interlaced separation form. This device reduces the omission errors caused by visual inspection and improves the accuracy of inspection by unfolding the assembly cylinder 21 after separation. In addition, the interlaced separation between the isolation plate 33 and the assembly cylinder 21 makes it convenient for the staff to directly remove the bulb 14 from the assembly cylinder 21. Furthermore, since the isolation plate 33 is symmetrically distributed on both sides of the assembly cylinder 21, when the isolation plate 33 and the assembly cylinder 21 are in a separated and interlaced state, it is equivalent to increasing the ventilation area between the inside of the assembly cylinder 21 and the external environment.
