[0002] LED lighting is recognized as the next-generation lighting technology due to its power saving, environmental protection and long service life. However, more than 70% of the electrical energy of LED is converted into heat, and heat dissipation is necessary. Although the LED lighting technology has made a leap forward, and there are reports of up to 200 lm of light emission per watt, LED heat dissipation is a very headache problem in LED lighting, becoming an obstacle on the popularization and development road of LED lighting lamps.
[0003] Most of the heat dissipation structures of the existing LED lamps used in street lamps utilize structures such as heat dissipation fins to conduct heat and exchange heat with the outside world. It is not convenient to have too much connection with the outside world because problems such as rainwater will affect the use of electrical components such as circuits, resulting in the lack of a more suitable physical heat dissipation structure. Summary of the Utility Model

[0007] Preferably, the lighting component includes a circuit board arranged inside the upper shell and externally connected to a power supply, at least one LED lamp is arranged on the circuit board, and a transparent protective shell is fixedly arranged on the circuit board outside the LED lamp.
[0008] Preferably, both the circuit board and the upper shell are arranged obliquely upward, and an air outlet hole is opened on one side of the lower position of the transparent protective shell.
[0009] Preferably, the second heat dissipation component includes a second air inlet formed in the transparent bottom case. A transparent plate is fixedly arranged in the transparent bottom case inside the second air inlet.

[0010] Preferably, the transparent bottom case and the upper case are spliced, and a support rod is also threadedly connected to one side after splicing.
[0011] The technical effects and advantages of the present utility model: The outside air enters from the inside of the first air inlet on the outside of the transparent protection case inside the upper case, and then flows into the second air inlet and the U-shaped circuit of the first blocking plate through the gap between the U-shaped plate and the upper case, so as to cool the space between the inside of the upper case and the transparent protection case. Then, by setting the second air inlet, the outside air can flow around the blockage of the second blocking plate and flow between the transparent plate and the transparent protection case.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0018] The present invention provides an LED street lamp heat pipe heat dissipation device as shown in the figure, which includes an upper housing 3. A transparent bottom shell 2 is arranged at the bottom of the upper housing 3. A first heat dissipation component is arranged on the upper housing 3. A second heat dissipation component is arranged on the transparent bottom shell 2. A lighting component is arranged inside the upper housing 3.
[0019] The first heat dissipation component includes a first air inlet hole 4 opened on the upper housing 3. A U-shaped plate 6 is fixedly connected to the inner wall of the upper housing 3 inside the first air inlet hole 4. At least one of the two sides of the U-shaped plate 6 is fixedly connected with an L-shaped plate 14. A first partition plate 7 fixedly connected to the inner wall of the upper housing 3 is arranged at the top middle of the L-shaped plate 14. The air in the U-shaped plate (6) can flow into the second air inlet hole (1) through the gap between the U-shaped plate (6) and the upper housing (3) and enter the inside of the upper housing (3) through the U-shaped circuit of the first partition plate (7).
[0020] Specifically, the lighting component includes a circuit board 11 arranged inside the upper housing 3 and externally connected to a power supply. At least one LED lamp 12 is arranged on the circuit board 11. A transparent protective shell 10 is fixedly arranged on the circuit board 11 outside the LED lamp 12.
[0021] Specifically, both the circuit board 11 and the upper housing 3 are arranged obliquely upward. An air outlet hole 8 is opened on one side of the lower position of the transparent protective shell 10.
[0022] Specifically, the second heat dissipation component includes a second air inlet hole 1 opened on the transparent bottom shell 2. A transparent plate 9 is fixedly arranged inside the transparent bottom shell 2 inside the second air inlet hole 1. A second partition plate 13 that can block the second air inlet hole 1 is arranged on one side of the second air inlet hole 1 at the top of the transparent plate 9. A through hole is opened on the transparent bottom shell 2 between the second partition plate 13 and the second air inlet hole 1, and the through hole is on the same horizontal plane as the transparent plate 9.
[0023] Specifically, the transparent bottom shell 2 and the upper housing 3 are spliced, and a support rod 5 is also threadedly connected to one side after splicing.
[0024] Working principle: When using the present utility model, the circuit board 11 is powered on, and then the LED lamp 12 is lit for illumination. During this period, since the transparent protective case 10 and the transparent bottom case 2 are made of transparent materials, light can pass through them to illuminate the ground. Then, air from the outside enters the inside of the transparent protective case 10 outside the upper case 3 through the first air inlet hole 4. Then, it flows into the second air inlet hole 1 and the U-shaped circuit of the first partition board 7 through the gap between the U-shaped plate 6 and the upper case 3 and enters the inside of the upper case 3, so as to cool the space between the inside of the upper case 3 and the transparent protective case 10. Then, due to the setting of the second air inlet hole 1, outside air can flow around the blockage of the second partition board 13 and enter the space between the transparent plate 9 and the transparent protective case 10. Then, due to the setting of the air outlet hole 8, when the air flows between the transparent protective case 10 and the inside of the upper case 3, heat exchange and air flow can be carried out on the air inside the transparent protective case 10. Then, due to the position setting of the air outlet hole 8, it can prevent the air from directly contacting the outside rainwater, with strong protection and avoiding the situation of rainwater entering in the morning while cooling. Then, the settings of the first partition board 7, the L-shaped plate 14, and the second partition board 13 are all to directly block the air inlet to prevent rainwater from directly entering. Then, due to the diversion and through-hole settings of the U-shaped plate 6, the blocked rainwater can be blocked and drained out. The whole process has a relatively reasonable and simple structure. The whole process does not require additional electrical components and uses pure physical cooling, increasing the effect of communicating with the outside world.
[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
