Description

Technical Field

[0001] The utility model relates to the technical field of solar street lamps, and more specifically, to a solar street lamp with efficient heat dissipation. Background Art

[0002] A solar street lamp consists of a solar battery pack, a solar panel assembly, a light source, a street lamp controller, and a lamp house and lamp post. The output power supply is mostly AC 110V or 220V. It is powered by a crystalline silicon solar cell, stores electrical energy with a maintenance-free valve-regulated sealed battery (gel battery), uses a super bright LED lamp as the light source, and is controlled by an intelligent charge and discharge controller. It has the advantages of simple installation, low investment, good safety performance, energy conservation and environmental protection.

[0003] The existing solar street lamps use an LED lamp board to form the light source, and there are some problems in long-term use. Since the LED lamp board is usually enclosed and fixed inside the lamp shell, the heat generated by itself cannot be discharged. At the same time, the gap at the installation position of the LED lamp board is small, and it is easy to cause the temperature of the LED lamp board to be too high after long-term heat accumulation, resulting in damage, which in turn affects the lighting effect and increases the time for maintenance and replacement. In view of this, we propose a solar street lamp with efficient heat dissipation. Summary of the Utility Model

[0024] The LED lamp body 3 includes a base 4. A wire routing cavity 401 is arranged on one side of the base 4 close to the side end of the lamp post 1, and a slot is arranged at the top of the wire routing cavity 401. An LED lamp board 5 is installed at the bottom of the base 4. A plurality of heat dissipation slots 402 communicating with the position of the LED lamp board 5 are arranged in an array on both the left and right sides of the base 4. An upper cover 405 is installed at the top of the wire routing cavity 401 at the position of the slot. A heat dissipation member 6 is fixedly arranged at the top of the upper cover 405. A bottom cover 7 is detachably installed at the bottom of the base 4; the design of the wire routing cavity 401 facilitates the power cord of the LED lamp board 5 to pass through and be connected to the power cord of the solar panel 2 to achieve the effect of being powered on. The setting of the slot at the top is used to communicate with the heat dissipation member 6, so that the wind blown out by the heat dissipation member 6 can enter the interior of the wire routing cavity 401. The setting of the bottom cover 7 is used to enclose the LED lamp board 5 inside, playing a protective role without affecting lighting.

[0025] An arc-shaped guide seat 701 is fixedly arranged at the top of the bottom cover 7 at the position of the wire routing cavity 401. Two guide plates 702 are arranged obliquely towards each other at the top of the arc-shaped guide seat 701, and the side ends of the two guide plates 702 are close to one side of the LED lamp board 5; the arc-shaped surface at the top of the arc-shaped guide seat 701 can change the wind direction, and the cross-designed guide plates 702 can reduce the blowing range and increase the wind force, facilitating blowing and dissipating heat at the position of the LED lamp board 5.

[0026] In an embodiment of the utility model, the heat dissipation slot 402 is an inclined slot in a V shape, and the top of the heat dissipation slot 402 is set as a plane; the inverted V shape can form a slope surface without affecting the ventilation effect, which can reduce the probability of rainwater entering the wire routing cavity 401 and reduce the influence on the waterproof effect of the LED lamp board 5.

[0027] In an embodiment of the utility model, two limit blocks 403 are fixedly arranged on both the left and right side surfaces of the wire routing cavity 401, and a dust-proof board 404 for blocking the outer openings of a plurality of heat dissipation slots 402 is installed between the two limit blocks 403; restricting the position of the dust-proof board 404 through the limit blocks 403 can facilitate disassembly and assembly operations, so that the dust-proof board 404 can be removed to clean the surface dust while maintaining the LED lamp body 3. Blocking the outer openings of the heat dissipation slots 402 through the dust-proof board 404 can reduce the entry of dust into the wire routing cavity 401 and play a dust-proof role.

[0028] In an embodiment of the present utility model, the heat dissipation member 6 includes an installation cylinder base 601. Inside the installation cylinder base 601, a heat dissipation fan 602 corresponding to the grooving position of the wire routing cavity 401 is installed. At the top of the installation cylinder base 601, a dust-proof ring 603 is fixedly provided. At the top of the dust-proof ring 603, a top plate 604 is fixedly provided. At the outer edge of the bottom of the top plate 604, a rain-proof ring plate 605 is fixedly provided. A ventilation cavity is formed between the dust-proof ring 603 and the rain-proof ring plate 605. The heat dissipation fan 602 is connected to the power supply of the solar panel 2 and can be started to work, achieving the effect of blowing and dissipating heat. The settings of the dust-proof ring 603 and the top plate 604 can achieve the rain-proof effect without affecting air circulation. The design of the rain-proof ring plate 605 can further improve the rain-proof effect. At the same time, the ventilation grooves 606 designed on the outer wall of the rain-proof ring plate 605 can improve the ventilation effect.

[0029] In an embodiment of the present utility model, a plurality of ventilation grooves 606 are annularly and arrayedly formed on the outer wall of the rain-proof ring plate 605, and the ventilation grooves 606 are designed to be inclined upward from the outside to the inside on the rain-proof ring plate 605. Through the inclined design, rainwater can be blocked while maintaining the ventilation effect, thereby reducing the probability of rainwater contacting the dust-proof ring 603.

[0030] In an embodiment of the present utility model, on the side of the arc-shaped guide seat 701 close to the LED lamp board 5, an extension plate 703 corresponding to the positions of the two guide plates 702 is fixedly provided. An L-shaped baffle 704 is fixedly provided between the two guide plates 702 and the two extension plates 703. The combination of the extension plate 703 and the L-shaped baffle 704 can further narrow the blowing range and achieve the effect of compressing the air volume, so as to improve the air outlet strength at the position of the LED lamp board 5 and improve the heat dissipation effect.

[0031] In an embodiment of the present utility model, a diversion cavity 705 is formed between the arc-shaped guide seat 701 and the guide plate 702, and a compression cavity 706 communicating with the diversion cavity 705 is formed between the extension plate 703 and the L-shaped baffle 704. Under the action of the diversion cavity 705, the wind direction can be changed, and the wind speed can be increased in cooperation with the compression cavity 706 to enhance the blowing effect.

[0032] Working principle: This embodiment provides a solar street lamp with efficient heat dissipation. When in use, when the LED lamp panel 5 is working, the power supply of the solar panel 2 can be used to start the cooling fan 602 inside the heat dissipation component 6, so that it can blow air into the interior along the slot position at the top of the wire routing cavity 401. Then, through the diversion cavity 705 formed by the cooperation of the arc-shaped guide seat 701 and the guide plate 702, the wind direction can be changed, and at the same time, the blowing range can be reduced. Next, through the compression cavity 706 formed between the extension plate 703 and the L-shaped baffle 704, the air volume can be further compressed, so that the wind speed passing through the orifice of the compression cavity 706 is increased, strengthening the effect of blowing away the accumulated heat at the position of the LED lamp panel 5. Through continuous blowing, the heat can be discharged along the wind from the heat dissipation slots 402 on both sides of the wire routing cavity 401, thereby maintaining the stability of the temperature at the position of the LED lamp panel 5 and reducing the probability of continuous high-temperature operation. The dust-proof plate 404 provided at the outer opening of the heat dissipation slot 402 can prevent dust from entering, and at the same time, it can also deal with the dust on the surface of the dust-proof plate 404 when blowing air, maintaining good ventilation. And the heat dissipation slot 402 is designed in an inverted V shape to form an inclined slope, reducing the probability of rainwater entering. At the same time, the ventilation slots 606 obliquely designed on the outer wall of the rain-proof ring plate 605 can also play a rain-proof effect. In this way, the safety of the overall structural cooperation can be maintained, the influence of the open structure on the working environment of the LED lamp panel 5 can be reduced, and the heat dissipation effect of the LED lamp panel 5 can be strengthened.

[0033] The embodiments disclosed in this utility model are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of this utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
