Description

Technical Field

[0001] This invention relates to the field of LED lights, and more specifically, to an explosion-proof, high-efficiency, and energy-saving LED light. Background Technology

[0002] LED, or light-emitting diode, is a solid-state semiconductor device that directly converts electricity into light. LED energy-saving lamps use high-brightness white LEDs as the light source, offering high luminous efficiency, low power consumption, long lifespan, easy control, maintenance-free operation, and safety and environmental friendliness. As a new generation of solid-state cold light source, it provides soft, vibrant, and rich light with low loss and energy consumption. Suitable for long-term lighting in homes, shopping malls, banks, hospitals, hotels, restaurants, and other public places, it features flicker-free direct current, offering excellent eye protection and making it the best choice for desk lamps and flashlights.

[0003] Existing explosion-proof, high-efficiency, and energy-saving LED lamps, after prolonged use in dusty environments, tend to accumulate a layer of dust on the outer surface of their transparent sealed covers. Furthermore, since LED lamps are typically installed at a high position, timely cleaning is difficult. This severely affects the light emitted by the LED lamps, significantly reducing their effectiveness. In contrast, using high-power LED lamps to ensure lighting performance would increase energy consumption. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide an explosion-proof, high-efficiency, and energy-saving LED lamp.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An explosion-proof, high-efficiency, and energy-saving LED lamp includes a metal housing, a lampshade fixedly connected to the bottom of the metal housing, a connecting post fixedly connected to the middle of the top of the metal housing, a constant current power supply module fixedly connected to the top inside the metal housing, a third heat dissipation fin uniformly fixedly connected to the outer surface of the constant current power supply module, an LED lamp fixedly connected to the top inside the lampshade, and a second heat dissipation fin fixedly connected to the top of the LED lamp.

[0007] The top of the lampshade is provided with a convection component for heat dissipation, and the outer surface of the lampshade is fixedly connected with an air curtain component for preventing dust from adhering to the surface of the metal shell.

[0008] The convection assembly includes an annular frame fixed to the top of the lampshade, an air pump fixed to the inside of the metal housing, and external threaded rings fixed to both sides of the top of the metal housing. The outer surface of the external threaded ring is threaded with a metal mesh frame. The output and input ends of the air pump are fixedly connected with air pipes. An air jet is provided at the top of the annular frame. A flow guide frame is fixedly connected to the outer surface of the annular frame. The interior of the flow guide frame is in communication with the interior of the annular frame.

[0009] Furthermore, the outer surface of the metal shell is uniformly provided with a plurality of first heat dissipation fins, one end of the air pipe at the air pump input end extends into the interior of the external threaded ring, the number of air jets is the same as that of the third heat dissipation fins, and the air jets are located at the bottom of the third heat dissipation fins.

[0010] Furthermore, the lampshade has multiple connecting holes at its top edge, the LED lamp has an adjustment component at its top edge, and the lampshade has an unfolding component at its bottom edge.

[0011] Furthermore, the control component includes a fixed frame fixed at the top center of the LED lamp and an adjustment switch fixed inside the top of the lampshade. The output end of the adjustment switch is provided with a knob. Piston cylinders are fixedly connected to both sides of the inner surface of the fixed frame. A piston is slidably connected inside the piston cylinder. A telescopic rod is fixedly connected to one side of the piston. A rack is fixedly connected to one side of the piston. Thermal conductive silicone grease is provided in the cavity between the piston cylinder and the fixed frame. Nitrogen gas is provided inside the piston cylinder.

[0012] Furthermore, one side of the telescopic rod extends out of the interior of the piston cylinder, the rack is connected to the knob, and the adjustment switch is connected to the LED light via a wire.

[0013] Furthermore, the bottom of the fixing frame is open, the thermal grease is in contact with the top of the LED, and the thermal grease is tightly wrapped around the outer surface of the piston cylinder.

[0014] Furthermore, the unfolding assembly includes a storage groove at the bottom edge of the lampshade and servo motors fixed on both sides of the top of the lampshade. The output end of the servo motor is fixedly connected to a threaded rod. A rubber ring is slidably connected inside the storage groove. An annular filter is fixedly connected to the bottom of the rubber ring. A connecting ring is fixedly connected to the bottom of the annular filter. An L-shaped plate is symmetrically fixedly connected to the top of the connecting ring.

[0015] Furthermore, the bottom of the threaded rod extends into the interior of the lampshade, and the bottom of the threaded rod penetrates the interior of the L-shaped plate. The interior of the L-shaped plate is provided with threads, and the threaded rod is connected to the L-shaped plate through the threads. The rubber ring and the storage groove are slidably adapted to each other.

[0016] Furthermore, the air curtain assembly includes an annular air supply pipe fixed to the top of the outer surface of the lampshade. The top of the annular air supply pipe has multiple air distribution holes, and a return pipe is symmetrically fixedly connected to the inner side of the annular air supply pipe.

[0017] Furthermore, one side of the return pipe extends into the interior of the lampshade, and one end of the return pipe extends into the interior of the guide frame. The return pipe is L-shaped, and the interior of the annular air supply pipe is interconnected with the interior of the return pipe. The return pipe is also interconnected with the interior of the guide frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This solution uses a convection component to transfer the heat generated by the constant current power module to the interior of the third heat sink. Airflow blows onto the surface of the third heat sink, carrying away the heat inside and thus cooling the LED light. This prevents localized overheating and avoids internal fires that could cause the light fixture to explode. Simultaneously, some airflow is ejected from the air distribution holes, forming a ring-shaped air curtain around the metal casing, protecting the surrounding area. When dust approaches the metal casing, the airflow from the air distribution holes blows it away, preventing dust from freely settling on the surface of the metal casing. This not only prevents dust but also provides auxiliary cooling.

[0020] 2. This solution incorporates a control component. When the LED light operates at full power and generates a large amount of heat, the heat is transferred to the interior of the piston cylinder via thermal grease. This heats the nitrogen gas inside the piston cylinder, causing it to expand and push the piston and telescopic rod to one side. The rack then drives a knob to rotate, adjusting the current of the LED light and reducing its brightness. This allows the LED light to operate at low power consumption, reducing heat generation and energy consumption, effectively improving the energy efficiency of the LED light, and preventing explosions caused by high temperatures.

[0021] 3. This solution uses a servo motor to drive a threaded rod, which in turn moves an L-shaped plate downwards via threads. The connecting ring then moves the annular filter out of the storage slot. When airflow is ejected from the nozzle, it enters the lampshade through the connecting hole and then flows out through the annular filter. The airflow carries a large amount of heat outwards, further accelerating heat dissipation and improving the lifespan of the LED light. Attached Figure Description

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 9 An explosion-proof, high-efficiency, and energy-saving LED lamp includes a metal housing 1, a lampshade 4 fixedly connected to the bottom of the metal housing 1, a connecting post 2 fixedly connected to the middle of the top of the metal housing 1, a constant current power module 10 fixedly connected to the top inside the metal housing 1, a third heat dissipation fin 9 uniformly fixedly connected to the outer surface of the constant current power module 10, an LED lamp 7 fixedly connected to the top inside the lampshade 4, a second heat dissipation fin 8 fixedly connected to the top of the LED lamp 7, a convection component 5 for convection heat dissipation provided on the top of the lampshade 4, and an air curtain component 6 for preventing dust from adhering to the surface of the metal housing 1 fixedly connected to the outer surface of the lampshade 4.

[0041] like Figures 2-4 As shown, the convection assembly 5 includes an annular frame 51 fixed to the top of the lampshade 4, an air pump 53 fixed to the inside of the metal housing 1, and external threaded rings 59 fixed to both sides of the top of the metal housing 1. The outer surface of the external threaded rings 59 is threaded with a metal mesh frame 55. The output and input ends of the air pump 53 are fixedly connected with air pipes 54. The top of the annular frame 51 is provided with a jet nozzle 58. The outer surface of the annular frame 51 is fixedly connected with a guide frame 52. The interior of the guide frame 52 is in communication with the interior of the annular frame 51.

[0042] Multiple first heat dissipation fins 3 are evenly distributed on the outer surface of the metal shell 1. One end of the air pipe 54 at the input end of the air pump 53 extends into the interior of the external threaded ring 59. The number of air jets 58 is the same as that of the third heat dissipation fins 9, and the air jets 58 are located at the bottom of the third heat dissipation fins 9.

[0043] Multiple connecting holes are provided at the top edge of the lampshade 4, an adjustment component 56 is provided at the top edge of the LED lamp 7, and an unfolding component 57 is provided at the bottom edge of the lampshade 4.

[0044] like Figure 4 , Figure 7 and Figure 8 As shown, the air curtain assembly 6 includes an annular air supply pipe 62 fixed to the top of the outer surface of the lampshade 4. The top of the annular air supply pipe 62 is provided with multiple air distribution holes 63, and a return pipe 61 is symmetrically fixedly connected to the inner side of the annular air supply pipe 62.

[0045] One side of the return pipe 61 extends into the interior of the lamp cover 4, and one end of the return pipe 61 extends into the interior of the guide frame 52. The return pipe 61 is L-shaped. The interior of the annular air supply pipe 62 is connected to the interior of the return pipe 61, and the interior of the return pipe 61 is connected to the interior of the guide frame 52.

[0046] When explosion-proof LED lights are used in a dusty environment, dust will adhere to the surface of the light fixture. The dust will reduce the heat dissipation effect of the light fixture. Over time, the internal flammable materials of the light fixture may ignite due to excessive temperature, leading to the explosion of the light fixture.

[0047] 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.

[0048] 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.

[0049] like Figure 5 and Figure 6As 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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 with low power consumption. 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.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
