Description

Technical Field

[0001] The invention relates to the technical field of outdoor lighting, in particular to an LED street lamp with a lampshade that is protected from condensation of water vapor. Background Art

[0002] LED street lights refer to street lights made of LED lamps. They have unique advantages such as high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. They are of great significance to energy saving in urban lighting.

[0003] When LED street lamps are used at night, the circuit board of the lamp group will generate a high temperature due to long-term use, which will cause a large temperature difference between the inside and outside of the lamp housing. In humid weather such as rain, the temperature difference between the inside and outside of the lamp housing will cause more water vapor condensation inside the lamp housing, thus affecting the lighting effect and service life of the street lamp;

When rain drops on the outer wall of the conical ventilator, it will be blocked by the inclined setting of the conical ventilator outlet during its downward sliding process and cannot flow into the conical ventilator.

The heated annular hollow cabin will heat the cotton cloth that absorbs rainwater, so that the heat dissipation device can efficiently utilize the hot air generated when the lamp group dissipates heat. Part of the water vapor blown upward from the second slide bar will be absorbed by the cotton yarn, and the other part will be dissipated outward due to the positive pressure generated by the air flow inside the conical ventilator, causing the air outlet of the conical ventilator to open, thereby reducing the water content inside the lamp shell due to the discharge of water vapor;

[0018] 3. The clamping plate squeezes the inner wall of the lamp group to ensure that after the lamp group ages and deforms due to long-term outdoor use, its clamping plate can still stably engage with the limit rod, avoiding the lamp group from losing the function of engaging with the lamp shell due to aging, avoiding the risk of the lamp group falling due to aging and loosening after long-term use, and improving the safety of the lamp group when in use.

[0034] 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.

[0035] Embodiments of the present invention

[0036] See also Figures 1 to 4 A LED street lamp with a lampshade that prevents water vapor condensation comprises a lamp housing 1 and a closing component 11 arranged inside the lamp housing 1, wherein the closing component 11 comprises an annular cone plate 111 and a conical ventilator 119, wherein the annular cone plate 111 is rotatably connected to the top of the lamp housing 1, wherein the inner side wall of the annular cone plate 111 is distributed in an annular array and fixedly connected with a rubber strip 114, wherein the conical ventilator 119 is fixedly connected to the middle of the upper surface of the annular cone plate 111, wherein the outer wall of the conical ventilator 119 is symmetrically slidably connected with a special-shaped sealing plate 112, wherein the bottom of the special-shaped sealing plate 112 and the conical ventilator 119 are fixedly connected. A first spring 113 is fixedly connected thereto, and second springs 115 are fixedly connected thereto in a circular array at the bottom of the annular cone plate 111, and an annular plate 116 is fixedly connected to the bottom of the second spring 115, and a special-shaped cabin 117 is fixedly connected to the middle of the lower surface of the annular cone plate 111, and cotton yarn 118 is arranged inside the special-shaped cabin 117, and an air outlet is provided on the outer wall of the conical ventilator 119, and the front end of the special-shaped sealing plate 112 is matched with the air outlet of the conical ventilator 119, and the height of the end of the special-shaped sealing plate 112 is half of the height of the air outlet, and a water retaining ring is provided at the bottom of the inner cavity of the special-shaped cabin 117.

[0037] In actual application, this embodiment:

[0038] When a small amount of rainfall occurs outdoors and the wind is relatively weak, the rain will drip and gather on the top of the annular cone plate 111. At this time, due to the blocking of the air outlet of the conical ventilator 119 by the special-shaped sealing plate 112, the rain cannot enter the interior of the lamp housing 1 through the air outlet of the conical ventilator 119; when the outdoor rainfall increases and the wind increases, the external wind will drive the annular cone plate 111 to start rotating through the rubber strip 114 acting on the inner wall of the annular cone plate 111. The rainwater accumulated inside the annular cone plate 111 will fly around the annular cone plate 111 under the action of the centrifugal force generated by the rotation of the annular cone plate 111. At this time, the special-shaped sealing plate 112 inside the conical ventilator 119 will be dispersed in the air outlet of the conical ventilator 119 under the action of the centrifugal force of the annular cone plate 111. The cone vent 119 slides downward, thereby turning the air outlet of the cone ventilator 119 into an open state. At this time, the air outside the lamp housing 1 enters the interior of the lamp housing 1 through the air outlet of the cone ventilator 119. The temperature difference between the inner cavity of the lamp housing 1 and the outside of the lamp housing 1 is reduced by ventilation inside and outside the lamp housing 1, thereby reducing the condensation of water vapor inside the lamp housing 1. When raindrops fall on the outer wall of the cone ventilator 119, they will be blocked by the inclined air outlet of the cone ventilator 119 during the downward sliding process and cannot flow into the interior of the cone ventilator 119. When the external heavy rain is scattered by the wind and falls into the interior of the cone ventilator 119, the rainwater attached to the interior of the cone ventilator 119 will flow downward along the arc surface of the inner wall of the special-shaped cabin 117, and will be finally absorbed by the cotton yarn 118.

[0039] See also Figures 4 to 5 The lamp housing 1 is also provided with an adsorption assembly 12, which includes a turbofan 121 rotatably connected to the interior of the lamp housing 1 and located below the special-shaped cabin 117, a first slide bar 122 is fixedly connected to the middle of the lower surface of the turbofan 121, an air duct 1210 adapted to the turbofan 121 is opened through the interior of the lamp housing 1, a second slide bar 124 is threadedly connected to the interior of the first slide bar 122, and a limit plate is fixedly connected to the interior of the lamp housing 1 and located below the turbofan 121 125, the second sliding rod 124 is slidably connected to the middle part of the limiting plate 125, the bottom of the second sliding rod 124 is fixedly connected with an annular hollow cabin 126, the upper surface of the annular hollow cabin 126 and the limiting plate 125 are fixedly connected with a third spring 129, the upper surface of the annular hollow cabin 126 is provided with air guide grooves 128 distributed in an annular array, the bottom of the annular hollow cabin 126 is provided with cotton cloth 127, and the upper end of the air guide groove 128 is inclined toward the side close to the second sliding rod 124.

[0040] The bottom of the lamp housing 1 is buckled with a lampshade plate 4, the interior of the lamp housing 1 is fixedly connected with a lamp group 2, and a heat dissipation device 3 is arranged on the top of the lamp group 2. The heat dissipation device 3 includes a fan group 31, a first air duct 32, and a second air duct 33. The fan group 31 is fixedly connected to the upper surface of the lamp group 2, and the second air duct 33 is fixedly connected to the side of the fan group 31 close to the turbofan 121. The end of the second air duct 33 away from the fan group 31 is fixedly connected to the inside of the annular hollow cabin 126, and the first air duct 32 is fixedly connected to the side of the fan group 31 away from the turbofan 121. The inner wall of the lamp housing 1 is fixedly connected with an air guide plate 34, and the end of the first air duct 32 away from the fan group 31 is fixedly connected to the inner wall of the lamp housing 1. It is fixedly connected to the interior of the air guide plate 34, the first slide bar 122 is adapted to the bottom of the special-shaped cabin 117, annular grooves are provided at both upper and lower ends of the inner wall of the first slide bar 122, a threaded groove is provided between the annular grooves of the first slide bar 122, a protrusion 123 is provided on the outer wall of the second slide bar 124, the protrusion 123 is slidably connected to the threaded groove and the inside of the annular groove, the air guide groove 128 faces the center of the lower surface of the second slide bar 124, a fan is arranged inside the fan unit 31, the second air duct 33 and the first air duct 32 are fixedly connected to the fan unit 31, both are located above the fan unit 31, and an air outlet is arranged at the lower end of the air guide plate 34, and the air outlet is inclined at forty-five degrees.

[0041] In actual application, this embodiment:

[0042] When there is a violent storm outside, the humidity in the air will increase sharply, and water vapor will easily condense inside the lamp housing 1. A large amount of rainwater will accumulate on the top of the annular cone plate 111. Under the action of the gravity of the rainwater, the second spring 115 will elastically shrink, so that the annular cone plate 111 will slide downward inside the lamp housing 1. The sliding of the annular cone plate 111 will cause the special-shaped cabin 117 to press the second slide bar 124 inside the first slide bar 122, so that the protrusion 123 on the outer wall of the second slide bar 124 slides from the annular slide groove above the inner cavity of the turbofan 121 into the threaded groove. At the same time, the blown wind will hit the inside of the air duct 1210 and pass through the air duct 122 inside the air duct 1210. 10 is narrowed to accelerate, and the accelerated wind is blown to the outer wall of the turbofan 121 inside the air duct 1210. The turbofan 121 starts to rotate due to the high-speed wind. When the turbofan 121 rotates, the protrusion 123 on the outer wall of the second slide bar 124 slides into the threaded groove on the inner wall of the first slide bar 122, so that the second slide bar 124 moves downward during the rotation of the first slide bar 122. The downward sliding of the second slide bar 124 drives the annular hollow cabin 126 and the cotton cloth 127 to slide downward together, and the third spring 129 is stretched and elastically stretched, and finally the cotton cloth 127 is fitted with the *lamp cover plate 4. When the fan unit 31 is running, the heat generated when the lamp group 2 is powered on will be dissipated. The heat is absorbed and transferred into the air guide plate 34 and the annular hollow cabin 126 through the first air duct 32 and the second air duct 33 respectively. The hot air introduced into the air guide plate 34 will dry and blow the water vapor on the lampshade plate 4 under the guidance of the inner cavity of the air guide plate 34, so that the residual water vapor in the lampshade plate 4 condenses and is blown to the cotton cloth 127. The hot air transferred into the annular hollow cabin 126 will heat the annular hollow cabin 126, and the heated annular hollow cabin 126 will heat the cotton cloth 127 that absorbs rainwater, so that the heat dissipation device 3 can efficiently utilize the hot air generated when the lamp group 2 dissipates heat, so that the cotton cloth 127 absorbs water and the cotton cloth 127 is heated. The moisture is dried in time and injected into the annular hollow cabin 126. As the hot air is continuously injected, a positive pressure is generated. The air inside the annular hollow cabin 126 is blown upward to the inside of the second slide bar 124 through the air guide groove 128. During the blowing process, the water vapor generated by the evaporation and drying of the cotton cloth 127 will be blown to the inside of the second slide bar 124 under the action of the airflow. Part of the water vapor blown upward inside the second slide bar 124 will be absorbed by the cotton yarn 118, and the other part will be due to the positive pressure generated by the airflow inside the conical ventilator 119, which will cause the air outlet of the conical ventilator 119 to open and dissipate outward, thereby reducing the water content inside the lamp housing 1 due to the discharge of water vapor.

[0043] See also Figures 6 to 9The inner cavity of the lamp housing 1 is symmetrically provided with a quick-release assembly 5, which includes a slider 51 and a fourth spring 52. The slider 51 is symmetrically slidably connected to the inner wall of the lamp housing 1, and the fourth spring 52 is fixedly connected to the side close to the slider 51. The outer wall of the slider 51 is fixedly connected to a limit rod 53, and the end of the limit rod 53 away from the slider 51 is fixedly connected to a circular plate 54, and the side close to the circular plate 54 is fixedly connected to a gear rod 55. The outer wall of the limit rod 53 is slidably connected to a clamping plate 57, and a fifth spring 56 is fixedly connected between the clamping plate 57 and the circular plate 54. The inner wall of the lamp housing 1 is fixedly connected A sleeve box 58 is connected, and a gear 59 is rotatably connected inside the sleeve box 58. The gear 59 meshes with the gear rod 55. A screw rod 510 is fixedly connected to the side of the gear 59 close to the inner wall of the lamp housing 1. A sleeve 511 is threadedly connected to the outer wall of the screw rod 510. A square plate 512 is fixedly connected to the outer wall of the sleeve 511. The square plate 512 is slidably connected to the inside of the lamp housing 1. A sixth spring 513 is fixedly connected between the square plate 512 and the inner wall of the lamp housing 1. The two sliders 51 are symmetrically arranged with the sleeve box 58 as the center. A slot is arranged on the top of the lamp group 2. The side of the clamping plate 57 close to the lamp group 2 fits tightly with the lamp group 2.

[0044] In actual application, this embodiment:

[0045] When the staff needs to buckle the lamp group 2 and the lamp housing 1, the staff slides the lamp group 2 into the interior of the lamp housing 1. When the top clamp of the lamp group 2 fits the outer wall of the limit rod 53, continuing to push the lamp group 2 into the lamp housing 1 will cause the limit rod 53 to drive the slider 51 to slide relatively inside the lamp housing 1. The fourth spring 52 is stretched and elastically extends. In the process of moving together with the limit rod 53, the circular plate 54 will drive the gear 59 meshing with it to rotate inside the sleeve box 58 through the gear rod 55. The rotation of the gear 59 drives the screw rod 510 fixedly connected to it to rotate together. When the screw rod 510 rotates, it will cause the sleeve to be connected through a threaded connection. 511 slides to the outside of the lamp housing 1, and the sixth spring 513 is squeezed and elastically contracts. As the lamp group 2 moves upward, the side of the clamp 57 close to the slider 51 is also pushed by the lamp group 2. The clamp 57 slides on the outer wall of the limit rod 53 under the push of the lamp group 2, and the fifth spring 56 is squeezed and elastically contracts. Finally, the clamp 57 fits tightly against the inner wall of the lamp group 2. When the lampshade plate 4 needs to be removed, the staff presses the sleeve 511, and the sleeve 511 slides to the side close to the screw rod 510, causing the screw rod 510 to rotate and push the gear rod 55 away in the relative direction, so that the limit rod 53 and the lampshade plate 4 are no longer stuck.

[0046] The clamping plate 57 squeezes the inner wall of the lamp group 2 to ensure that after the lamp group 2 ages and deforms due to long-term outdoor use, its clamping plate can still stably clamp with the limit rod 53, thereby preventing the lamp group 2 from losing the function of clamping with the lamp housing 1 due to aging, and avoiding the risk of the lamp group 2 falling due to aging and loosening after long-term use, thereby improving the safety of the lamp group 2 when in use.
