DETAILED DESCRIPTION

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0028] Please see Figures 1-7 This application discloses a tri-proof lamp with a high-efficiency heat dissipation structure, comprising a lamp holder 1, a sealing plate 9, and a first positioning plate 12. The lamp holder 1 serves as the main support structure of the lamp, and a lamp tube 2 is installed inside to provide illumination. The lamp tube 2 is electrically connected to a power module 5 for power supply. A lamp cover 3 is detachably connected to the upper side of the lamp holder 1, which protects the lamp tube 2 and diffuses light. A perforated groove 4 is provided at the bottom of the lamp holder 1 to form a heat dissipation channel. The power module 5 is fixedly installed inside the perforated groove 4 for power conversion and control, and a temperature sensor 6 is fixedly installed inside the perforated groove 4 for real-time monitoring of internal temperature changes.

[0029] A heat sink 7 is bolted to the outside of the permeable groove 4, forming the main heat dissipation surface. Heat sink 7 has heat dissipation holes 8 on its exterior for air circulation. A sealing plate 9 is slidably connected to the outside of the heat sink 7 to achieve adjustable heat dissipation. Two sets of symmetrically arranged limiting plates 11 are fixedly connected to the outside of the heat sink 7 to guide the sliding trajectory of the sealing plate 9. The sealing plate 9 is slidably connected to the inner side of the two sets of limiting plates 11 to ensure movement stability. Through holes 10 are provided on the outside of the sealing plate 9 for heat dissipation. The through holes 10 and heat dissipation holes 8 are matched and staggered to form a controllable heat dissipation channel. Both the heat sink 7 and the sealing plate 9 are made of aluminum to optimize thermal conductivity. Several sets of heat dissipation holes 8 and through holes 10 are arranged in an array to increase the heat dissipation area.

[0030] The first positioning plate 12 is fixedly connected to the bottom of the heat sink 7 as a reset reference point. A reset mechanism is installed between the sealing plate 9 and the first positioning plate 12 to realize the automatic reset function. The reset mechanism includes a connecting block 13 and a tension spring 14. The connecting block 13 is fixedly connected to both sides of the sealing plate 9 as a force fulcrum. The tension spring 14 is fixedly connected between the first positioning plate 12 and the connecting block 13 to provide reset tension, and the tension spring 14 is always in a stretched state to maintain preload. One end of the sealing plate 9 abuts against the first positioning plate 12 to form an initial limit.

[0031] The other end of the sealing plate 9 is equipped with an alignment mechanism to realize the adjustment function of the heat dissipation hole 8. The alignment mechanism includes a second positioning plate 15, a fixed plate 16, a micro motor 17, a rotating rod 18, and a pull rope 19. The second positioning plate 15 is fixedly connected to the outside of the heat dissipation plate 7 as the sliding endpoint positioning. The fixed plate 16 is fixedly connected to the lower side of the lamp holder 1 to provide a support base. There are two sets of fixed plates 16, which are arranged symmetrically to ensure structural balance. The micro motor 17 is fixedly connected to the outside of one set of fixed plates 16 to provide driving force. The rotating rod 18 is rotatably connected between the two sets of fixed plates 16 as a transmission hub. The pull rope 19 is fixedly connected to the outside of the rotating rod 18 to realize power transmission. The end of the pull rope 19 passes through the second positioning plate 15 and is fixedly connected to the end of the sealing plate 9 to complete the action transmission. When the sealing plate 9 abuts against the outside of the second positioning plate 15, the heat dissipation hole 8 and the through hole 10 are aligned to form the maximum heat dissipation channel.

[0032] The lamp holder 1 has connecting plates 20 fixedly connected to both sides for lamp installation and fixing. The connecting plates 20 have mounting holes 21 on the outside for easy connection with external brackets.

[0033] The working principle of the tri-proof lamp with a high-efficiency heat dissipation structure based on the embodiment is as follows: When the power module 5 built into the perforated groove 4 at the bottom of the lamp holder 1 is working continuously, it generates heat. In the initial stage, the heat dissipation plate 7 and the sealing plate 9, made of aluminum, dissipate heat through their own thermal conductivity. At this time, the heat dissipation holes 8 on the surface of the heat dissipation plate 7 and the through holes 10 on the outside of the sealing plate 9 are misaligned, forming a double-layer isolation structure, which not only ensures basic heat dissipation requirements but also prevents external contaminants from entering. When the power module 5 operates for a long time and causes heat to accumulate, the temperature sensor 6 inside the perforated groove 4 monitors the internal temperature rise in real time. When a signal is sent to the control system when the threshold is exceeded, the system will then start the micro motor 17 on the outside of the fixed plate 16, drive the rotating rod 18 to rotate and wind the pull rope 19. Under the guidance of the second positioning plate 15, the sealing plate 9 is pulled to slide along the track of the limiting plate 11 towards the end of the heat sink 7. During the displacement process, the sealing plate 9 gradually unfolds against the tension of the tension spring 14 until its end is in close contact with the second positioning plate 15. At this time, the through hole 10 is completely aligned with the heat sink 8, and the through slot 4 forms a direct convection channel with the outside through the through hole 10 to realize the rapid heat dissipation.

[0034] When the temperature sensor 6 detects that the temperature inside the permeable groove 4 has dropped to a safe range, the control system commands the micro motor 17 to reverse and release the pull rope 19. Under the elastic restoring force of the tension spring 14, the sealing plate 9 retracts along its original path, and the through hole 10 and the heat dissipation hole 8 return to their misaligned state, effectively blocking the flow of external air. This dynamic adjustment mechanism not only solves the forced heat dissipation requirement under continuous high-temperature conditions, but also maintains a closed and protective state under normal conditions. In particular, through the combination design of the aluminum movable sealing plate 9 and the fixed heat dissipation plate 7, the heat dissipation area is doubled, while the staggered hole positions are cleverly used to form a physical isolation barrier. The whole process does not require manual intervention. Through the precise coordination of temperature sensing and electromechanical linkage, the heat dissipation safety of the power module 5 under extreme conditions is ensured, and the technical defects of traditional heat dissipation structures that are susceptible to environmental humidity and dust corrosion are effectively avoided. This significantly improves the environmental adaptability and operational reliability of the tri-proof lamp under complex conditions.

[0035] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
