[0002] LED outdoor floodlights refer to lamps with a higher illumination on the illuminated surface than the surrounding environment. They are mainly used in large-scale work sites, building outlines, stadiums, overpasses, monuments, parks and flower beds. However, due to long-term outdoor work, external water vapor gradually enters the interior of the LED outdoor floodlight and gathers on the glass panel to form a layer of water mist, which has a negative impact on the use of the LED outdoor floodlight.

[0003] Among them, the patent number CN116624841A is a floodlight that prevents the generation of water mist. Two sets of breathing valves are fixedly connected to the upper surface of the lamp panel to discharge water vapor to the outside to solve the water mist situation. However, in actual use, only relying on a single breathing valve used for a long time can easily lead to the gradual deterioration of the sealing of the LED outdoor floodlight, making it more difficult to avoid the formation of water mist, and it is also impossible to ensure that the internal dryness and cleanliness of the LED outdoor floodlight are further affected.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-Figure 8 As shown, this embodiment is a self-balancing waterproof structure of an ultra-thin LED outdoor floodlight, comprising a housing 1, a sealing plate 2 is fixedly connected to the surface of the housing 1, a glass cover 3 is sealed and connected to the sealing plate 2, the glass cover 3 is a double-layer vacuum glass, which can reduce the influence of water mist on the outer wall of the glass cover 3 caused by the internal temperature of the housing 1, a rear cover 6 is fixedly connected to the side of the sealing plate 2 away from the housing 1, and a defogger mechanism is provided between the rear cover 6 and the housing 1;

[0031] The defogger mechanism includes a horizontally arranged heat dissipation pipe 7 located on the inner side of the rear cover 6. The sealing plate 2 and the rear cover 6 are both ultra-thin shells made of cast aluminum alloy. Cast aluminum alloy is widely used in electromechanical, automotive, aviation, aerospace and other fields due to its low density and high strength, and can meet the requirements of green, energy-saving and environmental protection.

[0032] The heat dissipation pipe 7 is vertically connected with two connecting pipes 9, the two connecting pipes 9 are connected with a heat dissipation chamber 14, a switching cylinder 11 is slidably connected in the heat dissipation pipe 7 for switching the two connecting pipes 9, and a bellows 8 is connected to the side of the heat dissipation pipe 7 away from the connecting pipe 9;

[0033] When the switching cylinder 11 slides in the heat dissipation tube 7, the connecting tube 9 corresponding to the vertical direction of the bellows 8 is connected, so that the high-temperature gas generated in the heat dissipation chamber 14 enters the bellows 8 through the connecting tube 9;

[0034] The inner wall of the housing 1 is clamped with a focusing plate 10 for the LED chip to penetrate, and a mounting frame 16 is fixedly connected to the back of the focusing plate 10. A shunt pipe 30 connected to the bellows 8 is penetrated and rotatably connected to the inner wall of the mounting frame 16, and a plurality of nozzles 31 extending toward the glass cover 3 and distributed at intervals are fixedly connected to the outer wall of the shunt pipe 30;

[0035] The bottom of the housing 1 is connected with a respirator 27, and the heat dissipation chamber 14 is arranged on the back of the LED lamp holder, which can utilize the heat generated by the LED lamp holder, and transport the air in the heat dissipation chamber 14 to the shunt pipe 30 connected with the bellows 8, and spray the air to the inner wall of the glass cover 3 through the nozzle 31 on the shunt pipe 30;

[0036] At the same time, when the shunt pipe 30 swings back and forth, the nozzle 31 can spray at different positions of the glass cover 3, and the hot air contacts the water vapor on the inner wall of the glass cover 3, so that the temperature of the inner wall of the glass cover 3 increases. As the temperature of the inner wall of the glass cover 3 increases, the water vapor condensed on the inner wall of the glass cover 3 begins to evaporate. Due to the continuous heating of the hot air, the water vapor can obtain enough energy to change from liquid to gas.

[0037] When the water vapor concentration in the box is too high, the air pressure inside and outside the lamp is balanced and waterproof and breathable under the action of the respirator 27, allowing air to flow freely under the action of the pressure difference between the inside and outside, while preventing the entry of moisture and dust. The respirator 27 is usually built with a waterproof and breathable membrane material, such as EPTFE film, expanded polytetrafluoroethylene or nano-membrane, which allows air molecules to pass through and prevents the entry of larger particles such as water droplets and dust;

[0038] When the temperature inside the housing 1 rises and the air pressure rises, part of the air is allowed to be discharged, so that the LED outdoor floodlight can be self-balanced and waterproof. By setting the respirator 27 to remove the internal water vapor in one direction, the actual use state of the lamp is optimized to the greatest extent, the service life and reliability of the lamp are extended to the maximum extent, and the problem of water vapor appearing inside the traditional LED outdoor floodlight, which affects the irradiation effect, is effectively solved;

[0039] The glass cover 3 is usually made of high-transmittance glass or polycarbonate and other materials to ensure the lighting effect of the lamp and has good waterproof performance. The glass cover 3 and the sealing plate 2 are sealed by a sealing ring, which is usually made of high-elastic rubber or silicone material. The power cord of the ultra-thin LED outdoor floodlight adopts waterproof equipment such as waterproof connectors and waterproof plastic tubes to ensure that it can operate normally in humid and rainy environments, which can ensure that the outdoor lamp can operate normally in harsh environments and provide safe and comfortable outdoor lighting services.

[0040] An electric push rod 13 is fixedly installed on one side of the rear cover 6, and the telescopic end of the electric push rod 13 is fixedly connected to the end of the switching cylinder 11. The electric push rod 13 located between the rear cover 6 and the housing 1 is started, and the telescopic end of the electric push rod 13 pushes the switching cylinder 11 to move, so that the corresponding switching cylinder 11 is moved. A vertical connecting port is provided on the outer wall of the switching cylinder 11, and the end of the heat dissipation pipe 7 away from the electric push rod 13 penetrates the outer wall of the rear cover 6, and the end of the switching cylinder 11 away from the electric push rod 13 is provided with a semicircular through groove, and a baffle corresponding to the end of the switching cylinder 11 is provided in the heat dissipation pipe 7;

[0041] When the switching cylinder 11 moves, the vertical connecting port on the switching cylinder 11 is connected with the bellows 8 and another connecting tube 9, so that the heat dissipation bin 14 can be connected with the bellows 8. At the same time, when the switching cylinder 11 moves, the opening at the end of the switching cylinder 11 contacts the baffle in the heat dissipation tube 7, and the end of the switching cylinder 11 is sealed to ensure that the high-temperature gas in the heat dissipation bin 14 can flow into the bellows 8 through the switching cylinder 11 and the heat dissipation tube 7.

[0042] A battery 12 is fixedly connected to one side of the housing 1, and a heat sink that penetrates the heat sink 14 and extends inward is fixedly connected to the outer wall of the battery 12. By arranging the heat sink 14, heat can be gathered in the heat sink 14, and the heat of the battery 12 and the LED lamp holder itself can be reasonably utilized, or an electric heater is installed in the heat sink 14 to heat the heat sink 14. A motor 32 is fixedly installed on one side of the bottom of the heat sink 14, and a fan for auxiliary heat dissipation is fixedly connected to the output end of the motor 32. The bottom of the heat sink 14 is connected to the air intake pipe 15;

[0043] A control panel is provided in the shell 1, and a processor, a data acquisition module and a signal execution module are provided inside the control panel. The data acquisition module includes a humidity sensor installed in the shell 1 for detection, which is used to collect the humidity inside the shell 1. If the humidity is ≥ the preset risk value, a rejection signal is generated and sent to the signal execution module. After receiving the rejection signal, the signal execution module controls the electric push rod 13 to switch, and at the same time, the nozzle 31 drives the fan located in the heat dissipation bin 14 to rotate, and the external air is sucked into the heat dissipation bin 14 through the intake pipe 15. The intake pipe 15 is provided with a filter net, which can filter the air, and then the hot air in the heat dissipation bin 14 is transported to the bellows 8, and then transported to the diversion pipe 30 through the bellows 8 for waterproof and defogging operations.

[0044] Example 2: Please refer to Figure 1-Figure 8 As shown, in the present embodiment, a self-balancing waterproof structure of an ultra-thin LED outdoor floodlight is provided, the end of the shunt pipe 30 passes through the mounting frame 16 and is fixedly connected to a transmission gear 29, the transmission gear 29 is meshed with a rack 28, and the end of the rack 28 is fixedly connected to a connecting frame 17;

[0045] When the connecting frame 17 moves, the rack 28 fixedly connected thereto can be pushed to move, and the rack 28 meshes with the transmission gear 29, so that the shunt pipe 30 fixedly connected to the transmission gear 29 rotates, and the spray angle and range of the nozzle 31 on the shunt pipe 30 can be adjusted to fully remove the mist or moisture on the inner wall of the glass cover 3.

[0046] The back of the focusing plate 10 is fixedly connected to two symmetrically arranged limiting rods 18, which penetrate the second connecting frame 17 and are slidably connected to the second connecting frame 17. The limiting rods 18 are sleeved with springs 19 that resist the second connecting frame 17 and the focusing plate 10. The limiting rods 18 are provided to limit the second connecting frame 17, so that the second connecting frame 17 can move stably in the horizontal direction.

[0047] Under the action of the spring 19, the second connecting frame 17 can assist the second connecting frame 17 to reset. When the second connecting frame 17 is pushed, the elastic force of the limit rod 18 is overcome to push the second connecting frame 17 to move, and the corresponding rack 28 is pushed by the second connecting frame 17 to make the shunt pipe 30 reciprocate and swing. The spray range of the nozzle 31 on the shunt pipe 30 accelerates the rapid drying of the water vapor on the inner wall of the glass cover 3.

[0048] A push plate 33 connected to the output end of the motor 32 is horizontally slidably connected to one side of the outer wall of the heat dissipation bin 14, and a turntable 24 is connected to the surface of the heat dissipation bin 14 in a fixed axis rotation manner. The turntable 24 is fixedly connected to a connecting shaft 34 that penetrates the heat dissipation bin 14 and is connected to the output end of the motor 32. Bevel gears are fixed on the ends of the connecting shaft 34 and the output shaft of the motor 32. The two bevel gears are internally meshed with each other. The module of the bevel gear on the output shaft of the motor 32 is smaller than the module of the bevel gear on the connecting shaft 34, so as to achieve reduced rotation.

[0049] When the fan in the heat dissipation bin 14 rotates, the connecting shaft 34 connected to the output shaft of the motor 1 32 can be rotated, so that the turntable 24 coaxially fixedly connected to the connecting shaft 34 can be rotated. An eccentric column is fixedly connected to the surface of the turntable 24, and a movable frame 25 slidably connected to the eccentric column on the turntable 24 is fixedly connected to the back of the push plate 33. A sliding groove for the eccentric column to be slidably connected is opened on the surface of the movable frame 25, and a horizontal limit block 26 is fixedly connected to one side of the movable frame 25;

[0050] When the turntable 24 rotates, the eccentric column on the turntable 24 slides in the sliding groove on the movable frame 25, and a movable block that slides with the limit block 26 is fixedly connected to one side of the heat dissipation bin 14. The eccentric column reciprocates to push the movable frame 25 to move in the horizontal direction, so that the push plate 33 fixedly connected to the movable frame 25 can move reciprocally;

[0051] The limit block 26 is fixedly connected to a bent knocking rod extending toward the air intake pipe 15 . The limit block 26 drives the knocking rod back and forth to contact the air intake pipe 15 , thereby preventing dust from accumulating at the bottom opening of the air intake pipe 15 and preventing blockage.

[0052] The end of the connecting frame 2 17 close to the pushing plate 33 penetrates and is slidably connected with a sliding block 20, the sliding block 20 is in contact with the surface of the pushing plate 33, and the contact surfaces of the sliding block 20 and the pushing plate 33 are both rough serrated. A vertically arranged connecting strip 22 is fixedly connected to the upper surface of the sliding block 20, and the top of the connecting strip 22 is fixedly connected to the pushing frame 21, and the outer contour of the telescopic end of the electric push rod 13 is fixedly connected to the pushing strip 23;

[0053] The surface of the push frame 21 is provided with a horizontal movable groove, and the movable groove provided on the push frame 21 can prevent the push frame 21 from interfering with the telescopic end of the electric push rod 13 when the corresponding push frame 21 moves;

[0054] When the telescopic end of the electric push rod 13 pushes the switching cylinder 11, the pushing bar 23 fixedly connected to the telescopic end of the electric push rod 13 pushes the pushing frame 21, and the connecting bar 22 fixedly connected to the pushing frame 21 pushes the pushing frame 21, so that the end of the sliding block 20 contacts the surface of the pushing plate 33, and under the action of friction, it can push the connecting frame 17 fixedly connected to the sliding block 20, and through the reciprocating movement of the connecting frame 17, the reciprocating rack 28 is pushed to make the corresponding shunt pipe 30 swing back and forth.

[0055] The outer wall of the shell 1 is movably connected to a connecting frame 5 through a pin shaft, and a movable rod 4 is movably connected to one side of the outer wall of the shell 1 near the bottom, and a movable column is fixedly connected to one end of the movable rod 4 away from the shell 1. A horizontally arranged sliding groove which is slidably connected to the movable column is provided on the surface of the connecting frame 5. By setting the movable rod 4 and the connecting frame 5, when the movable column on the movable rod 4 moves in the sliding groove on the connecting frame 5, a thread is provided on the surface of the movable column on the movable rod 4, and the position of the movable column on the movable rod 4 is fixed by bolts, so that the installation angle of the shell 1 can be adjusted, so that the floodlight has an inclined installation structure, which effectively avoids the infiltration of rainwater and accumulated water and can maintain good drainage performance.

[0056] Combining the first and second embodiments, it can be seen that by setting a defogger mechanism, the high-temperature gas or heated air in the heat dissipation chamber 14 is sprayed toward the inner wall of the glass cover 3 through the bellows 8, the shunt pipe 30 and the nozzle 31, so as to increase the temperature of the inner wall of the glass cover 33, evaporate the water vapor condensed on the inner wall of the glass, avoid the formation of water mist, and ensure the lighting effect of the lamp. The setting of the respirator 27 realizes the balance of air pressure inside and outside the lamp and the waterproof and breathable function;

[0057] When the temperature inside the shell 1 rises and causes the air pressure to rise, the respirator 27 allows part of the air to be discharged, which not only prevents the entry of water vapor and dust, but also ensures the dryness and cleanliness of the inside of the lamp, thereby extending the service life of the lamp. By sliding the switching cylinder 11 in the heat dissipation pipe 7, the connecting pipe 9 can be switched to be connected with the bellows 8, thereby realizing flexible utilization of the high-temperature gas in the heat dissipation chamber 14. While the switching cylinder 11 moves, the reciprocating swing of the shunt pipe 30 can enable the nozzle 31 to spray at different positions of the inner wall of the glass cover 3, thereby further improving the defogger effect, effectively solving the internal water vapor problem, avoiding the influence of water vapor on the illumination effect, and improving the lighting effect. By setting the self-balancing waterproof structure and the defogger mechanism, the service life and reliability of the lamp are further extended.

[0058] like Figure 1-Figure 8 As shown, the working process and principle of the present invention are as follows:

[0059] Step 1: Adjust the installation angle of the housing 1 so that the floodlight has an inclined installation structure, which effectively avoids the infiltration of rainwater and stagnant water and maintains good drainage performance. When the humidity in the housing 1 is ≥ the preset risk value, control the electric push rod 13 to switch, and at the same time, the nozzle 31 drives the fan in the heat dissipation chamber 14 to rotate, and the external air is sucked into the heat dissipation chamber 14 through the air intake pipe 15. By setting the heat dissipation plate in the heat dissipation chamber 14, the heat can be accumulated in the heat dissipation chamber 14. The electric push rod 13 pushes the switching cylinder 11 to slide in the heat dissipation pipe 7, and the switching cylinder 11 is moved upward. The vertical connecting port is connected with the bellows 8 and another connecting pipe 9, so that the heat dissipation chamber 14 can be connected with the bellows 8. The opening at the end of the switching cylinder 11 contacts the baffle in the heat dissipation tube 7, and the end of the switching cylinder 11 is sealed to ensure that the high-temperature gas in the heat dissipation chamber 14 can flow into the bellows 8 through the switching cylinder 11 and the heat dissipation tube 7, so that the connecting pipe 9 corresponding to the vertical direction of the bellows 8 is connected, so that the high-temperature gas in the heat dissipation chamber 14 enters the shunt pipe 30 and is sprayed into the inside of the glass cover 3 through the nozzle 31 on the shunt pipe 30;

[0060] Step 2: When the telescopic end of the electric push rod 13 pushes the switching cylinder 11, the pushing strip 23 fixedly connected to the telescopic end of the electric push rod 13 pushes the pushing frame 21, and the connecting strip 22 fixedly connected to the pushing frame 21 pushes the pushing frame 21, so that the end of the sliding block 20 contacts the surface of the pushing plate 33. When the nozzle 31 drives the fan to rotate, the connecting shaft 34 drivingly connected to the output end of the nozzle 31 rotates, so that the turntable 24 rotates, and the eccentric column on the turntable 24 slides in the movable frame 25. One side of the heat dissipation bin 14 is fixedly connected with a limit movable block with the limit block 26.

[0061] The movable frame 25 is reciprocatedly pushed by the eccentric column to move in the horizontal direction, so that the push plate 33 fixedly connected to the movable frame 25 can move reciprocally. When the end of the sliding block 20 contacts the surface of the push plate 33, the friction force can push the connecting frame 17 fixedly connected to the sliding block 20, so that the rack 28 can be reciprocated through the movement of the connecting frame 17. The rack 28 is meshed with the transmission gear 29, so that the shunt pipe 30 fixedly connected to the transmission gear 29 can be rotated, so that the spraying angle and range of the nozzle 31 on the shunt pipe 30 can be increased, and the fog or moisture on the inner wall of the glass cover 3 can be fully removed.
