[0002] With the development of technology, the application of LED lamps (light emitting diodes) is becoming more and more widespread, and more and more high-power LED lamps are designed for lighting, such as street lamps. Compared with existing lighting fixtures such as incandescent lamps or fluorescent lamps, LED lamps have many advantages such as good energy saving effect and long service life.

[0003] Most of the existing protective covers of LED lamp boards are fixedly installed on the lamp boards, and heat dissipation holes are opened on the side walls of the protective covers to dissipate the heat generated when the LEDs are in use. However, this heat dissipation method will cause dust and mosquitoes in the air to enter the interior of the protective cover. If dust and mosquitoes accumulate for a long time, they will directly affect the use of the LED lamp. In addition, when moisture in the air enters the interior of the protective cover, it is difficult to discharge the moisture quickly due to the slow air circulation inside the protective cover, which will affect the LED lamp again.

However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0022] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0023] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0024] like Figures 1 to 4 The main structure of a dustproof and waterproof LED light panel shown is a top plate 1, a protective frame 2 is installed at the lower end of the top plate 1, transparent glass is fixedly connected inside the protective frame 2, mounting plates 3 are fixedly connected to the side walls of the protective frame 2 and the top plate 1, screws 4 are threaded through the mounting plates 3 opened on the protective frame 2 and the top plate 1, the protective frame 2 and the top plate 1 are installed through a plurality of mounting plates 3 and screws 4 fixedly installed on their side walls, so that the protective frame 2 and the top plate 1 are squeezed more tightly through the screws 4, thereby preventing a gap between the top plate 1 and the protective frame 2, which causes dust and mosquitoes to enter the interior of the protective frame 2 through the gap, a dust removal frame 5 is fixedly connected to one side of the protective frame 2, and the side where the dust removal frame 5 is connected to the protective frame 2 is connected to a communication setting;

[0025] The dust removal frame 5 is fixedly connected to an air inlet frame 6 on one side away from the protective frame 2, and a fan 9 is rotatably installed inside the air inlet frame 6. A plurality of arc plates 8 are fixedly connected to the air inlet frame 6 near the opening, and the plurality of arc plates 8 are all arranged in an arc shape downward. Since the arc plates 8 installed at the opening of the air inlet frame 6 are arranged in an arc shape downward, water can be prevented from flowing into the interior of the air inlet frame 6 through the opening of the air inlet frame 6. A guide plate 15 is fixedly connected to the top surface of the air inlet frame 6. The guide plate 15 is arranged in an arc shape and extends to the outside of the air inlet frame 6. Thanks to the arrangement of the guide plate 15, rainwater and the like can be further prevented from flowing into the interior of the air inlet frame 6. A rectangular hole 10 is opened on the top surface of the dust removal frame 5, and a rectangular block 11 is slidably connected to the inside of the rectangular hole 10. A filter screen 12 is fixedly connected to one side of the rectangular block 11 close to the dust removal frame 5, and a limiting block 16 is symmetrically fixedly connected to the side wall of the rectangular block 11. The inner wall of the rectangular hole 10 is symmetrically provided with a limiting groove. The two limiting blocks 16 on the side wall of the rectangular block 11 are respectively slidably connected to the inside of the two limiting grooves provided on the inner wall of the rectangular hole 10, and the two limiting blocks 16 on the side wall of the rectangular block 11 are respectively slidably connected to the inside of the two limiting grooves provided on the inner wall of the rectangular hole 10, so as to limit the rectangular block 11 and the filter screen 12;

[0026] A sealing gasket is fixedly connected to the outer wall of the filter screen 12, and the sealing gasket is sealed and fitted inside the dust removal frame 5. An arc-shaped handle is fixedly connected to the top surface of the rectangular block 11. A collecting frame 17 is fixedly connected to the lower end of the filter screen 12, and one side of the collecting frame 17 fits one side of the filter screen 12. When too much dust is filtered on the side wall of the filter screen 12, the dust will fall into the inside of the collecting frame 17 fixedly connected at the lower end of the filter screen 12, so as to facilitate the collection of dust. A plurality of air outlet holes 13 are provided on the side of the protective frame 2 away from the dust removal frame 5, and the insides of the plurality of air outlet holes 13 provided on the side wall of the protective frame 2 are all fixedly connected with a one-way valve 14. Thanks to the one-way valves 14 fixedly installed in the plurality of air outlet holes 13, the one-way valve 14 can effectively prevent dust, mosquitoes and moisture in the outside air from entering the inside of the protective frame 2 through the air outlet holes 13, so as to discharge the hot air inside the protective frame 2, thereby completing heat exchange and accelerating the air circulation inside the protective frame 2.

[0027] A plurality of water outlet holes 18 are provided at the lower inner end of the air inlet frame 6. Thanks to the arrangement of the plurality of water outlet holes 18, if water enters the interior of the air inlet frame 6, the water will flow out through the plurality of water outlet holes 18, thereby further preventing water from entering the interior of the protective frame 2.

[0028] How it works

[0029] When the dustproof and waterproof LED light panel is used, the protective frame 2 and the top plate 1 are first installed through the multiple mounting plates 3 and screws 4 fixedly installed on the side walls thereof, so that the protective frame 2 and the top plate 1 are squeezed more tightly through the screws 4, thereby preventing a gap between the top plate 1 and the protective frame 2, which would cause dust and mosquitoes to enter the interior of the protective frame 2 through the gap. When the LED emits heat during use and needs to be cooled, the fan 9 rotatably installed inside the air inlet frame 6 is first started to suck air into the interior of the air inlet frame 6. At this time, because the arc plate 8 installed at the opening of the air inlet frame 6 is arranged in an arc shape downward, it is possible to prevent water from flowing into the interior of the air inlet frame 6 through the opening of the air inlet frame 6, and then the air is passed into the dust removal frame 5. Inside, the dust in the air is filtered by the filter 12 installed inside the dust removal frame 5, and then the filtered air will enter the inside of the protective frame 2 through the dust removal frame 5, and then the hot air inside the protective frame 2 will be discharged from the inside of the protective frame 2 through the air outlet 13 opened on the side wall of the protective frame 2. At this time, thanks to the one-way valve 14 fixedly installed in the multiple air outlets 13, the one-way valve 14 can effectively prevent dust, mosquitoes and moisture in the outside air from entering the inside of the protective frame 2 through the air outlet 13, so as to discharge the hot air inside the protective frame 2, thereby completing the heat exchange and accelerating the air circulation inside the protective frame 2, thereby preventing moisture in the air from being retained inside the protective frame 2 and affecting the normal operation of the LED light board.
