[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application; obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application, and all other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor fall within the scope of protection of the present application.

[0022] Please refer to Figures 1 to 9The utility model provides an explosion -proof high -efficient energy -saving LED lamp, including metal shell 1, the bottom fixed connection of metal shell 1 has lamp shade 4, the middle part of metal shell 1 top is fixedly connected with connecting column 2, the inner top of metal shell 1 is fixedly connected with constant current power module 10, the outer surface of constant current power module 10 is uniformly fixedly connected with third radiating fin 9, the inner top of lamp shade 4 is fixedly connected with LED lamp 7, the top of LED lamp 7 is fixedly connected with second radiating fin 8, the top of lamp shade 4 is provided with the convection assembly 5 for the convection heat dissipation, the outer surface of lamp shade 4 is fixedly connected with the air curtain assembly 6 for preventing dust from adhering to the surface of metal shell 1.

[0023] As shown in Figures 2-4 , the convection assembly 5 includes an annular frame 51 fixed to the top of the lamp shade 4, an air pump 53 fixed to the inner side of the metal shell 1, and outer threaded rings 59 fixed to the top of the metal shell 1 on both sides. The outer surface of the outer threaded ring 59 is threadedly connected with a metal mesh frame 55. The output end and the input end of the air pump 53 are fixedly connected with an air pipe 54. The top of the annular frame 51 is provided with a gas injection port 58. The outer surface of the annular frame 51 is fixedly connected with a flow guide frame 52. The inside of the flow guide frame 52 is in communication with the inside of the annular frame 51.

[0024] A plurality of first radiating fins 3 are uniformly provided on the outer surface of the metal shell 1. One end of the air pipe 54 of the input end of the air pump 53 extends to the inside of the outer threaded ring 59. The number of the gas injection ports 58 is the same as that of the third radiating fins 9. The gas injection ports 58 are located at the bottom of the third radiating fins 9.

[0025] A plurality of communication holes are provided at the edge of the inner top of the lamp shade 4. A regulation assembly 56 is provided at the edge of the top of the LED lamp 7. An unfolding assembly 57 is provided at the edge of the bottom of the lamp shade 4.

[0026] As shown in Figure 4 , Figure 7 and Figure 8 , the air curtain assembly 6 includes an annular air supplement pipe 62 fixed to the top of the outer surface of the lamp shade 4. A plurality of air distribution holes 63 are provided at the top of the annular air supplement pipe 62. The inner side of the annular air supplement pipe 62 is fixedly connected with a reflux pipe 61.

[0027] One side of the reflux pipe 61 extends to the inside of the lamp shade 4. One end of the reflux pipe 61 extends to the inside of the flow guide frame 52. The reflux pipe 61 is L-shaped. The inside of the annular air supplement pipe 62 is in communication with the inside of the reflux pipe 61. The reflux pipe 61 is in communication with the inside of the flow guide frame 52.

[0028] When the explosion -proof LED lamp is used in a smoke environment, dust will adhere to the surface of the lamp. The dust will reduce the heat dissipation effect of the lamp. In the long run, the internal combustible material of the lamp will catch fire due to the high temperature inside the lamp, causing the explosion of the lamp. Therefore, when the lamp works in a dusty environment, the air pump 53 is turned on. The air pump 53 draws external air into the interior of the guide frame 52 through two air pipes 54. When the airflow passes through the metal mesh frame 55, the metal mesh frame 55 can effectively filter out the dust in the environment. The airflow enters the interior of the annular frame 51 through the interior of the guide frame 52. The airflow is then ejected through multiple air nozzles 58 on the annular frame 51. Since the third heat dissipation fin 9 is located directly above the air nozzles 58, the heat generated by the constant current power module 10 will be transferred to the interior of the third heat dissipation fin 9. The airflow blows air onto the surface of the third heat dissipation fin 9, carrying away the heat inside the third heat dissipation fin 9, thereby cooling the LED lamp, avoiding local overheating, and preventing the lamp from catching fire and exploding. When the air pump 53 is working, when the airflow enters the interior of the guide frame 52, a portion of the airflow will enter the interior of the annular air supply pipe 62 through the return pipe 61. The airflow is ejected through the air distribution holes 63 on the annular air supply pipe 62. The airflow ejected from the air distribution holes 63 will form an annular air curtain around the metal shell 1, protecting the area around the metal shell 1. When dust approaches the metal shell 1, the airflow ejected from the air distribution holes 63 will blow the dust away, preventing the dust from freely falling onto the surface of the metal shell 1, reducing the probability of dust falling onto the surface of the metal shell 1, effectively preventing dust from adhering to the surface of the metal shell 1, and avoiding the accumulation of dust from reducing the heat dissipation effect of the lamp. At the same time, the rapid airflow around the metal shell 1 can carry away the heat around the first heat dissipation fin 3, accelerate the heat transfer, effectively cool the first heat dissipation fin 3, and further improve the heat dissipation effect. It not only plays a role in dust prevention, but also provides auxiliary cooling.

[0029] like Figure 5 and Figure 6 As shown, the control component 56 includes a fixed frame 561 fixed at the top center of the LED lamp 7 and an adjustment switch 568 fixed inside the top of the lamp cover 4. The output end of the adjustment switch 568 is provided with a knob 567. Piston cylinders 565 are fixedly connected to both sides of the inner surface of the fixed frame 561. A piston 562 is slidably connected inside the piston cylinder 565. A telescopic rod 563 is fixedly connected to one side of the piston 562. A rack 564 is fixedly connected to one side of the piston 562. Thermal grease 566 is provided in the cavity between the piston cylinder 565 and the fixed frame 561. Nitrogen gas is provided inside the piston cylinder 565.

[0030] One side of the telescopic rod 563 extends out of the interior of the piston cylinder 565, the rack 564 is connected to the knob 567, and the adjustment switch 568 is connected to the LED light 7 via a wire.

[0031] The bottom of the fixing frame 561 is open, and the thermal grease 566 is in contact with the top of the LED lamp 7. The thermal grease 566 is tightly wrapped around the outer surface of the piston cylinder 565.

[0032] When cooling the internal components of an LED lamp, the LED 7, operating at high intensity and full power, is also the main heat source in the lamp. Prolonged exposure to high temperatures can damage the LED chips. The large amount of heat generated by the LED 7 operating at full power is transferred through the thermal grease 566 to the interior of the piston cylinder 565, causing the internal temperature of the piston cylinder 565 to rise. This heats the nitrogen gas inside the piston cylinder 565, causing it to expand and push the piston 562 to one side. The piston 562 then moves the rack 564 via the telescopic rod 563. The rack 564 rotates the knob 567, which, through the adjustment switch 568, controls the current of the LED 7, reducing its brightness and enabling low-power lighting. This not only reduces heat generation but also energy consumption, effectively improving the energy efficiency of the LED lamp and preventing explosions caused by high temperatures.

[0033] like Figures 7-9 As shown, the unfolding component 57 includes a storage groove 577 opened at the bottom edge of the lampshade 4 and servo motors 571 fixed on both sides of the top of the lampshade 4. The output end of the servo motor 571 is fixedly connected to a threaded rod 572. A rubber ring 576 is slidably connected inside the storage groove 577. An annular filter 575 is fixedly connected to the bottom of the rubber ring 576. A connecting ring 573 is fixedly connected to the bottom of the annular filter 575. An L-shaped plate 574 is symmetrically fixedly connected to the top of the connecting ring 573.

[0034] The bottom of the threaded rod 572 extends into the interior of the lampshade 4, and the bottom of the threaded rod 572 penetrates the interior of the L-shaped plate 574. The interior of the L-shaped plate 574 is provided with threads, and the threaded rod 572 is connected to the L-shaped plate 574 through the threads. The rubber ring 576 and the storage groove 577 slide and adapt to each other.

[0035] When cooling the inside of the metal casing 1, the airflow is always in a state of circulation inside the metal casing 1, and the cooling effect is not obvious. When the servo motor 571 is turned on, it drives the threaded rod 572 to work. The threaded rod 572 drives the L-shaped plate 574 to move down through the thread, which drives the connecting ring 573 to move down as a whole. The connecting ring 573 drives the annular filter 575 to move out of the inside of the storage groove 577. The rubber ring 576 slides inside the storage groove 577, and the rubber ring 576 seals the gap between the storage groove 577 and the annular filter 575. When the airflow is ejected from the inside of the jet nozzle 58, the airflow will enter the inside of the lamp cover 4 through the connecting hole on the lamp cover 4, and then flow out to the outside through the annular filter 575 from the inside of the lamp cover 4. The airflow carries a lot of heat to the outside, further accelerating the heat flow and improving the service life of the LED lamp 7.

[0036] Instructions for use: When the LED light is working, turn on the air pump 53. The air pump 53 draws external air into the interior of the guide frame 52 through two air pipes 54. When the airflow passes through the metal mesh frame 55, the metal mesh frame 55 can effectively filter out dust in the environment. The airflow enters the interior of the annular frame 51 through the interior of the guide frame 52. The airflow is then ejected through multiple air nozzles 58 on the annular frame 51. Since the third heat dissipation fin 9 is located directly above the air nozzles 58, the airflow blows air onto the surface of the third heat dissipation fin 9. When the constant current power module 10 is working, the heat generated is transferred to the interior of the third heat dissipation fin 9, and the air nozzles 58 then carry away the heat from the interior of the third heat dissipation fin 9. At the same time, the servo motor 571 is turned on to drive the threaded rod 572 to work. The threaded rod 572 drives the L-shaped plate 574 to move down through the thread, which in turn drives the connecting ring 573 to move down as a whole. The connecting ring 573 drives the annular filter 575 to move out of the inside of the storage groove 577. The rubber ring 576 slides inside the storage groove 577 and seals the gap between the storage groove 577 and the annular filter 575. When the airflow is ejected from the inside of the jet nozzle 58, the airflow will enter the inside of the lamp cover 4 through the connecting hole on the lamp cover 4, and then flow out to the outside through the annular filter 575 from the inside of the lamp cover 4. The airflow carries a lot of heat to the outside, further improving the heat flow and improving the service life of the LED lamp 7. When the air pump 53 delivers airflow inside the airflow guide frame 52, a portion of the airflow enters the interior of the annular air supply pipe 62 through the return pipe 61. The airflow is ejected through the air distribution holes 63 on the annular air supply pipe 62. The airflow ejected from the air distribution holes 63 forms an annular air curtain around the metal shell 1, which protects the area around the metal shell 1. When dust approaches the metal shell 1, the airflow ejected from the air distribution holes 63 blows the dust away, preventing the dust from freely falling onto the surface of the metal shell 1, reducing the probability of dust falling onto the surface of the metal shell 1, effectively preventing dust from adhering to the surface of the metal shell 1, and avoiding the accumulation of dust from reducing the heat dissipation effect of the lamp. At the same time, the rapid airflow around the metal shell 1 can carry away the heat around the first heat dissipation fin 3, accelerate the heat transfer, and effectively cool the first heat dissipation fin 3. When the LED lamp 7 operates at full power, the large amount of heat generated is transferred to the interior of the piston cylinder 565 through the thermal grease 566. This raises the internal temperature of the piston cylinder 565, which in turn heats the nitrogen gas inside. The nitrogen gas expands as it heats up, pushing the piston 562 to one side. The piston 562 then moves the rack 564 via the telescopic rod 563. The rack 564 rotates the knob 567, which controls the current of the LED lamp 7 by adjusting the switch 568. This reduces the brightness of the LED lamp 7, enabling it to operate in a low-power lighting mode. This not only reduces heat generation but also energy consumption, effectively improving the energy efficiency of the LED lamp and preventing explosions caused by high temperatures.
