Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and more specifically, to an intelligent anti-fog street lamp. Background Art

[0002] Street lamps are common lighting devices in the prior art, often installed on both sides of roads to provide lighting for pedestrians and vehicles on the roads. The street lamps in the prior art are mainly divided into two types: power supply street lamps and solar street lamps, which provide convenience for people's travel. Street lamps mainly consist of a mounting bracket, a lampshade, a battery, and a light source device. By installing the battery and the light source device inside the lampshade, and then installing the lampshade at a high place through the mounting bracket to provide lighting for the road.

[0003] During the use of street lamps, the lampshade and the light source device need to be exposed to the outdoor environment for a long time. During long-term use, if the light emitted by the street lamp becomes blurred during use, it is usually a problem of water mist appearing on the inside or outside wall of the lampshade. The problem of water mist appearing inside the lampshade is generally that during the long-term use of the street lamp, moisture in the external environment penetrates into the inside of the lampshade. During the operation of the light source device inside the lampshade, heat is generated, causing the moisture to evaporate into water mist and condense inside the lampshade. The reason for the water mist adhering to the outer wall of the lampshade is that the heat generated during the operation of the light source device inside the lampshade causes a large temperature difference between the inside and outside of the lampshade, resulting in the generation of water mist on the outer wall of the lampshade. In view of the problem of water mist appearing on both the inside and outside of the lampshade in the prior art, we propose an intelligent anti-fog street lamp. Summary of the Invention

Detailed implementation manners

[0031] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0032] As Figures 1 to 10 shown, this embodiment proposes an intelligent anti-fog street lamp, including a lamp shade 1. An annular mounting plate 2 is fixedly connected to the middle of the lamp shade 1. A light source device 3 is arranged inside the annular mounting plate 2. The light source device 3 is a common lighting device in existing street lamps. The light source device 3 is mainly composed of a battery, electronic components and an LED lamp tube, which is a well-known existing technology device in the art.

[0033] It also includes a fin heat dissipation mechanism, which is arranged between the top of the lamp cover 1 and the light source device 3. The fin heat dissipation mechanism includes a fin heat dissipation component and an air flow cooling component. The fin heat dissipation component is arranged between the light source device 3 and the outer wall of the lamp cover 1. The fin heat dissipation component includes a sealing cover body 7 and heat dissipation fins 8. The sealing cover body 7 is fixedly connected to the annular mounting plate 2. The light source device 3 is located inside the sealing cover body 7. A plurality of heat dissipation fins 8 are fixedly connected to the top of the light source device 3. Heat dissipation notches are provided at the top of the heat dissipation fins 8. During the operation of the light source device 3, overheating problems may occur on the light source device 3. The heat generated by the light source device 3 is transferred through the heat dissipation fins 8, and the heat of the light source device 3 is transferred into the sealing cover body 7. The plurality of heat dissipation fins 8 can be arranged in a rectangular shape or a fan shape on the light source device 3. By providing heat dissipation notches on the heat dissipation fins 8, the contact area between the heat dissipation fins 8 and the outside is increased, improving the heat dissipation effect;

[0034] The air flow cooling component is connected in communication between the lamp cover 1 and the fin heat dissipation component. The air flow cooling component includes a mounting frame 9 and an air suction fan 10. The mounting frame 9 is fixedly connected through the top of the lamp cover 1. The bottom of the mounting frame 9 is in communication with the sealing cover body 7. The air suction fan 10 is arranged inside the mounting frame 9. When the air suction fan 10 is started, the outside air is conveyed into the mounting frame 9 through the air suction fan 10, and then the air continues to enter the sealing cover body 7, enabling the air to come into full contact with the plurality of heat dissipation fins 8. The heat on the heat dissipation fins 8 is carried and transferred by the air flow. At the same time, the air flow heats up. An encoder can be installed on the air suction fan 10 to transmit the operating data of the air suction fan 10 into the encoder, and the power and opening / closing time of the air suction fan 10 are controlled through the encoder.

[0035] A baffle plate 11 is fixedly connected inside the mounting frame 9. A plurality of slope grooves 12 are provided at the top of the baffle plate 11. A dust filter layer 13 is arranged inside the slope grooves 12. A water outlet hole 14 is provided at the bottom of the mounting frame 9. In order to enable the air in the external environment to enter the mounting frame 9 while preventing dust and rainwater in the external environment from entering the mounting frame 9, when the outside air enters the mounting frame 9 through the slope grooves 12, the dust and moisture in the air are first adsorbed by the dust filter layer 13. The bottom of the slope grooves 12 is in a slope shape, so even if moisture enters the slope grooves 12, it will flow along the inner bottom wall of the slope grooves 12 to the outside of the mounting frame 9. The function of the baffle plate 11 is to prevent moisture from entering the mounting frame 9 during rainy and snowy weather, enabling the moisture to flow on the baffle plate 11, and finally the moisture is discharged through the water outlet hole 14.

[0036] The top of the installation frame 9 is fixedly connected with a protective cover 15. The top of the protective cover 15 is arc-shaped. A plurality of slope slots 12 are all located at the bottom of the inner arc surface of the protective cover 15. During rain or snow, the protective cover 15 shields the slope slots 12 to prevent rain and snow from directly entering the slope slots 12.

[0037] An opening is formed at the bottom of the lamp shade 1. An upper transparent plate 4 and a lower transparent plate 5 are fixedly connected in the opening. An air outlet chamber 6 is formed between the upper transparent plate 4 and the lower transparent plate 5. The air flow discharge assembly is connected to one side of the fin heat dissipation assembly. The air flow discharge assembly discharges gas to the top of the upper transparent plate 4 or into the air outlet chamber 6 respectively. The air flow discharge assembly includes an air flow inlet cylinder 16 and an air nozzle 18 with a valve. The air flow inlet cylinder 16 is fixedly connected through the annular mounting plate 2. The upper side of the air flow inlet cylinder 16 is communicated with the sealing cover body 7 through a communicating cylinder 17. The bottom of the air flow inlet cylinder 16 is arc-shaped. A plurality of air nozzles 18 are arranged on the inner arc surface of the air flow inlet cylinder 16. The air outlet end of the air nozzle 18 faces the upper transparent plate 4. Among them, an air inlet groove is communicated between the bottom of the air flow inlet cylinder 16 and the upper transparent plate 4. After the air flow is transported into the sealing cover body 7 for heat dissipation, the heat dissipation air flow enters the installation frame 9 through the communicating cylinder 17, and then the air flow enters the lower side of the air flow inlet cylinder 16. If water mist adheres to the upper transparent plate 4 in the lamp shade 1, the heat dissipation gas is ejected through a plurality of air nozzles 18 to dry the water mist adhering to the upper transparent plate 4. When water mist appears outside the lower transparent plate 5, the heat dissipation air flow is transported into the air outlet chamber 6. During the flow of the heat dissipation air flow in the air outlet chamber 6, the surface temperature of the lower transparent plate 5 increases, preventing water mist from adhering to the lower transparent plate 5.

[0038] A closing plate 19 is arranged in the air inlet groove. The closing plate 19 is rotatably connected to the upper transparent plate 4 through a rotating shaft seat 20. A magnetic attraction device 21 is arranged on the air inlet groove. An iron sheet 22 is fixedly connected to the closing plate 19. When it is necessary to make the air flow enter the air outlet chamber 6, the magnetic connection relationship between the magnetic attraction device 21 and the iron sheet 22 is released by controlling the magnetic attraction device 21. Under the pushing action of the air flow, the closing plate 19 rotates along the center point of the rotating shaft seat 20, so that the closing plate 19 flows out of the air inlet groove, and the heat dissipation gas enters the air outlet chamber 6.

[0039] The bottom of the upper transparent plate 4 is provided with a mounting groove, and a water absorption layer 23 is arranged in the mounting groove. The top end of the lower transparent plate 5 is fixedly connected with a slope-shaped strip 24. When the heat dissipation gas flows in the air outlet chamber 6 to increase the temperature of the lower transparent plate 5, since the water absorption layer 23 provided on the upper transparent plate 4 has the effect of adsorbing moisture in the air, the water absorption layer 23 is likely to become wet. When the heat dissipation gas flows in the air outlet chamber 6, after the heat dissipation gas passes through the slope-shaped strip 24, the heat dissipation gas moves upward along the inclined inner wall of the slope-shaped strip 24, so that the heat dissipation gas contacts the water absorption layer 23 to dry the water absorption layer 23.

[0040] A plurality of ventilation holes 25 are provided at the bottoms of the lower transparent plate 5 and the lamp cover 1. After the heat dissipation gas blows between the lower transparent plate 5 and the upper transparent plate 4 respectively, it is finally discharged through the ventilation holes 25 at the corresponding positions.

[0041] The working principle of this intelligent anti-fog street lamp: First, install the lamp cover 1 on the brackets on both sides of the road. During use, the light source device 3 emits light, and the light passes through the upper transparent plate 4 and the lower transparent plate 5 to provide lighting for the road. According to different seasons, the usage power and opening and closing time of the air intake fan 10 can be adjusted. For example, in summer, there may be more water mist retained in the lamp cover 1, and the heat dissipation requirement for the light source device 3 is higher. The air intake fan 10 is controlled by an encoder to be turned on, and the outside air flow is conveyed into the installation frame 9 through the air intake fan 10, and then the air flow enters the sealed cover body 7, so that the air flow makes full contact with a plurality of heat dissipation fins 8. The heat on the heat dissipation fins 8 is carried and transferred by the air flow, and the heat dissipation air flow is conveyed into the gas inlet cylinder, and then the valve on the air nozzle 18 is opened to dry the water mist retained on the upper transparent plate 4 by the air flow.

[0042] In autumn and winter, because of the temperature difference inside and outside the lamp cover 1, when water mist appears on the lower transparent plate 5, the magnetic connection relationship with the iron sheet 22 is released by controlling the magnetic attraction device 21, so that the closing plate 19 rotates along the center point of the rotating shaft seat 20 under the pushing action of the air flow, and the closing plate 19 flows through the air inlet groove, and the heat dissipation gas enters the air outlet chamber 6. During the flow of the heat dissipation air flow in the air outlet chamber 6, the surface temperature of the lower transparent plate 5 increases, avoiding the situation of water mist adhering to the lower transparent plate 5.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
