Technical Field
[0001] This utility model relates to the field of LED street light technology, and in particular to an LED street light with a convenient heat dissipation structure for installation. Background Technology
[0002] Solar LED streetlights are a type of green and energy-saving streetlight that utilizes solar energy. Solar panels convert solar energy into electrical energy to power the LED streetlights. They are characterized by high energy efficiency, high utilization rate, low pollution, and low operating costs, and are widely used in road lighting, parks and scenic spots, community squares, campuses, and remote areas.
[0003] Solar LED streetlights accumulate heat over long periods of operation. If this heat is not properly managed, it can affect the efficiency of the LED lights and even shorten their lifespan. The traditional solution is to use passive heat dissipation devices such as heat sinks, heat dissipation strips, and heat pipes to distribute the heat generated by the LEDs and reduce their temperature. This method is simple and easy to implement, but its heat dissipation effect is greatly affected by the environment. For example, in the summer in the south, the temperature is high for a long time, and the heat dissipation effect is not very obvious. In this case, active heat dissipation devices such as fans, water cooling, and heat pipes should be used to force the heat to be distributed. However, water cooling requires coolant, but as the usage time increases, the coolant will evaporate due to evaporation and other reasons, gradually decreasing, and manual replenishment of coolant is costly.
[0004] Based on the above, this utility model proposes an LED street light with a convenient heat dissipation structure for installation. Utility Model Content
[0005] To overcome the shortcomings of heat dissipation fins, heat dissipation spokes, and heat dissipation plugs, which are greatly affected by the environment, water cooling has a better heat dissipation effect, but the coolant will evaporate due to evaporation and other reasons, and the maintenance cost of manual replenishment is high, the purpose of this utility model is to provide an LED street light with a convenient heat dissipation structure.
[0006] The technical solution of this utility model is: an LED street light with a convenient heat dissipation structure, comprising a shell, mounting bracket, light strip, solar panel, fan, hollow plate, plug, guide rail, baffle, fixing block, pull rope, and elastic rope. Mounting brackets are fixedly connected to both the left and right sides of the bottom of the shell. A light strip is installed on the upper right wall of the shell. A solar panel is installed on the top of the shell. A fan is installed in the upper part of the inner shell. The fan, light strip, and solar panel are electrically connected. A hollow plate is fixedly connected to the left side of the shell, and a [missing information - likely a device or component] is snapped into the lower part of the hollow plate. The plug has guide rails fixed to both the front and rear sides of the right side of the hollow plate. Several baffles are slidably connected between the front and rear guide rails. The baffles are also slidably connected to the outer shell. Several fixing blocks are fixed to both the front and rear sides of the outer shell. The baffles are evenly arranged from top to bottom along the outer shell. The fixing blocks are also evenly arranged from top to bottom along the outer shell. The baffles are connected to each other by pull ropes. The uppermost baffle is connected to the upper part of the hollow plate by a tension rope. The lowermost baffle is equipped with a drive assembly.
[0007] As an improvement to the above solution, a drive assembly is also included. The drive assembly includes an electric slide rail, a slider, and a rain sensor. An electric slide rail is installed between the lower sides of the front and rear guide rails. A slider is slidably connected to the electric slide rail. The slider is connected to the bottommost baffle. A rain sensor is installed on the electric slide rail.
[0008] As an improvement to the above solution, a filter screen is also included, with a filter screen for filtering out impurities fixed to the top wall of the hollow plate.
[0009] As an improvement to the above solution, it also includes a collection frame and a backing plate. The collection frame is fixed to the lower part of the outer shell, and the backing plate is snapped onto the lower right wall of the collection frame.
[0010] As an improvement to the above solution, the rain sensor is electrically connected to the motorized sliding rail.
[0011] As an improvement to the above solution, several square holes are opened on both the front and back walls of the outer shell.
[0012] This utility model has the following advantages: First, it uses a fan and square holes to dissipate hot air. Second, it uses the natural cooling effect and evaporation process of rainwater inside the hollow plate to remove the remaining heat, thereby effectively reducing the temperature of the street light. This design is not only environmentally friendly and energy-saving, but also eliminates the need for workers to replenish the liquid, and has the advantages of high cost-effectiveness and strong adaptability. Furthermore, the opening and closing of the square holes are controlled by rainwater sensors, electric slide rails, sliders, baffles, etc., thereby preventing rainwater from continuously entering the shell through the square holes during the rainy season, thus effectively preventing rainwater erosion and protecting the circuit from being affected.
[0013] This invention uses a collection frame to store rainwater, which can absorb heat conducted from the ground when the ground temperature is high, thereby preventing external high temperatures from affecting the light strips and increasing their service life. Attached Figure Description

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] An LED street light with an easy-to-install heat dissipation structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a housing 1, mounting brackets 2, light strips 3, solar panels 4, a fan 5, a hollow plate 6, a filter screen 7, a plug 61, a guide rail 8, a baffle 9, a fixing block 10, a pull rope 11, and a tension rope 111. The front and rear walls of the housing 1 have at least twelve square holes. There are two mounting brackets 2, which are fixed to the left and right sides of the bottom of the housing 1. The light strips 3 are installed on the upper right wall of the housing 1. The solar panel 4 is installed on the top of the housing 1. A fan 5 is installed inside the upper part of the housing 1. The fan 5, light strips 3, and solar panel 4 are electrically connected. The hollow plate 6 is fixed to the left side of the housing 1, and a plug 61 is snapped into the lower part of the hollow plate 6 for filtering debris. The filter screen 7 is fixed to the top wall of the hollow plate 6. There are two guide rails 8, which are fixed to the front and rear parts of the right side of the hollow plate 6 respectively. Four baffles 9 are slidably connected between the two guide rails 8. The four baffles 9 are also slidably connected to the outer shell 1. Eight fixing blocks 10 are fixed to the front and rear sides of the outer shell 1. The four baffles 9 are evenly arranged from top to bottom along the outer shell 1. The fixing blocks 10 on the front and rear sides are also evenly arranged from top to bottom along the outer shell 1. There are three pull ropes 11. The three pull ropes 11 are connected between two adjacent baffles 9. The tension rope 111 is connected between the uppermost baffle 9 and the upper part of the hollow plate 6. The lowermost baffle 9 is equipped with a drive assembly.
[0025] like Figure 6 As shown, it also includes a drive assembly, which includes an electric slide rail 12, a slider 121 and a rain sensor 13. The electric slide rail 12 is installed between the lower sides of the two guide rails 8. The slider 121 is slidably connected to the electric slide rail 12 and is connected to the bottommost baffle 9. The rain sensor 13 is installed on the electric slide rail 12 and is electrically connected to the electric slide rail 12.
[0026] When using this device, the mounting bracket 2 is fixed together with the ground cage. At this time, the street light is installed. Then, the system is tested to ensure that the street light is working properly. The solar panel 4 will convert solar energy into electrical energy to power the light strip 3 for lighting and the fan 5 for operation. As the light strip 3 works for a long time, heat will accumulate. The fan 5 will blow air into the outer shell 1 to accelerate the air circulation inside the outer shell 1. The hot air will then be dissipated through the square holes on the outer shell 1, thereby achieving heat dissipation for the LED street light. When it rains, rainwater passes through the filter screen 7 into the hollow plate 6. The hollow plate 6 will store the rainwater. The natural cooling effect and evaporation process of the rainwater will also take away heat, thereby effectively reducing the temperature of the street light.
[0027] During the rainy season, the heat accumulated by the light strip 3 can be absorbed by the hollow plate 6 filled with rainwater. In order to prevent rainwater from continuously entering the housing 1 through the square hole and the water vapor from not evaporating in time and affecting the operation of the circuit inside the housing 1, the rain sensor 13 will control the electric slide rail 12 to drive the slider 121 to move downward, thereby driving the bottom baffle 9 to move downward, and then driving the other baffles 9 to move downward through the pull rope 11. The tension rope 111 will deform, and the downward-moving baffles 9 will cover the square hole on the housing 1 to prevent rainwater from continuously entering the housing 1.
[0028] After the rainy season ends, the rain sensor 13 controls the electric slide rail 12 to move the slider 121 upward, thereby moving the bottommost baffle 9 upward and resetting. At the same time, under the elastic action of the tension rope 111, the topmost baffle 9 will move the other baffles 9 upward and reset through the pull rope 11. The baffles 9 that have moved upward and reset no longer cover the square hole, and the air inside the outer shell 1 can continue to convect with the outside through the square hole, thereby continuing to dissipate heat. In summary, the fan 5 and the square hole are used to dissipate the hot air first, and then the natural cooling effect and evaporation process of the rainwater in the hollow plate 6 remove the remaining heat, thereby effectively reducing the temperature of the street light. This design is not only environmentally friendly and energy-saving, but also does not require workers to replenish the liquid, and has the advantages of high cost-effectiveness and strong adaptability. Furthermore, the opening and closing of the square hole is controlled by the rain sensor 13, the electric slide rail 12, the slider 121, and the baffle 9, thereby preventing rainwater from continuously entering the interior of the outer shell 1 through the square hole during the rainy season, thus effectively preventing rainwater erosion and protecting the circuit from being affected.
[0029] Example 2
[0030] Based on Example 1, such as Figure 1 and Figure 7 As shown, it also includes a collection frame 14 and a backing plate 15. The collection frame 14 is fixed to the lower part of the outer casing 1, and the backing plate 15 is snapped onto the lower side of the right wall of the collection frame 14.
[0031] When the rainy season arrives, rainwater will drip into the collection box 14, which can store rainwater. When the weather is hot, the ground temperature will be high. In order to prevent the ground temperature from being conducted to the upper part of the outer casing 1, the rainwater in the collection box 14 will absorb the heat conducted in, thereby preventing the external high temperature from affecting the light strip 3 and increasing the service life of the light strip 3.
[0032] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
