Abstract
Description

[0002] In recent years, due to the development of LED technology, LED lighting has begun to be recognized and adopted by most users. Various LED lamps emerge in an endless stream, and the structures of LED lamps are also diverse.
[0003] However, the existing high-power LED street lamps require good heat dissipation in terms of structure because the photoelectric conversion rate of LEDs is only about 35%. Although it has improved in recent years, it is still limited. The rest is converted into electrothermal energy, forming a relatively high junction temperature, which causes light decay of the LEDs and then shortens their service life. The forms of heat dissipation include heat conduction, heat flow and heat radiation. At present, most of the heat dissipation technology designs of LED street lamps focus on heat conduction, and the design mainly focuses on increasing physical quantities and expanding the specific surface area of heat dissipation. After the heat energy generated during the operation of the LED is conducted to the heat dissipation body by this heat conduction structure, the heat energy can only be slowly dissipated into the air by natural diffusion, and the heat dissipation effect is not very ideal. There is an urgent need in the current LED industry to further improve the heat dissipation technology to reduce the junction temperature and reduce light decay. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0024] Please refer to Figures 1-5 , the present invention provides a technical solution: a high-lumen LED light energy street lamp, including a lamp slot 1 and a housing 2. The lamp slot 1 is arranged in the center of the housing 2. Ventilation devices 3 are arranged on both sides of the housing 2. The ventilation device 3 includes a plurality of cooling fans 4 and ventilation holes 5. A first ventilation pipeline 6, a second ventilation pipeline 7, a third ventilation pipeline 8, and a fourth ventilation pipeline 9 are arranged on the periphery of the lamp slot 1. The first ventilation pipeline 6 and the second ventilation pipeline 7 are arranged above the lamp slot 1 and are symmetrically arranged. The third ventilation pipeline 8 and the fourth ventilation pipeline 9 are arranged below the lamp slot 1 and are symmetrically arranged. A ventilation groove 10 is further arranged at the rear side of the lamp slot 1. A light output mirror 11 is arranged on the surface of the lamp slot 1. The first ventilation pipeline 6 and the second ventilation pipeline 7 are respectively connected to the air outlet 12 of the cooling fan 4. The third ventilation pipeline 8 and the fourth ventilation pipeline 9 are also respectively connected to the air outlet 12 on the other side of the cooling fan 4. An LED light source 13 is arranged inside the lamp slot 1.
[0025] Specifically, heat insulation boards 14 are arranged on the upper and lower sides inside the first ventilation pipeline 6, the second ventilation pipeline 7, the third ventilation pipeline 8, and the fourth ventilation pipeline 9. By arranging the heat insulation boards 14, the accumulation of heat in the ventilation pipeline can be effectively prevented, thereby improving the heat dissipation efficiency. In addition, the heat insulation board 14 can also protect the LED light source 13 from the influence of high temperature and extend its service life.
[0026] Specifically, the LED light source 13 is an LED light strip. By designing the light source as an LED light strip, the distribution of the light source is more uniform, thereby improving the lighting effect. The use of the LED light strip can also reduce the overall power consumption, further improving the energy efficiency ratio. The flexibility of the LED light strip makes it easier to adapt to different-shaped lamp slots 1.
[0027] Specifically, rain covers 15 are provided at both the top and bottom of the outer shell 2, and the rain covers 15 are made of transparent or translucent materials.
[0028] Specifically, a waterproof sealing ring 16 is also provided inside the outer shell 2. By setting the waterproof sealing ring 16, the outer shell 2 has good waterproof performance, ensuring that under harsh weather conditions, the street lamp can still work normally and the internal electronic components will not be damaged due to rain intrusion.
[0029] Specifically, both sides of the lamp slot 1 are inclined inward, and guide surfaces 17 are also provided on both sides of the lamp slot 1. Through the above settings, the LED strip lights can be better placed into the lamp slot 1.
[0030] Specifically, a number of fixing bolts 18 are also provided on the outer shell 2. By setting the number of fixing bolts 18, the outer shell 2 and the lamp slot 1 can be firmly connected together, ensuring that they will not loosen or fall off during use. The use of the fixing bolts 18 also facilitates the later maintenance and replacement of the LED light source 13, improving the maintainability of the street lamp.
[0031] Specifically, a filter screen 19 is also provided inside the ventilation hole 5. By setting the filter screen 19, dust and impurities in the air are effectively filtered before entering the ventilation device 3, thus avoiding the blockage of the cooling fan 4 and the ventilation pipeline, and ensuring the long-term stable operation of the ventilation system. The use of the filter screen 19 also helps to reduce the maintenance frequency and extend the service life of the street lamp.
[0032] Specifically, the material of the outer shell 2 is high-strength aluminum alloy, which has good corrosion resistance and impact resistance and can adapt to various harsh outdoor environments. At the same time, the aluminum alloy has excellent thermal conductivity, which helps to improve the overall heat dissipation effect and further enhance the stability and reliability of the street lamp.
[0033] A specific application example of this embodiment is:
[0034] When this device is in use, the LED light source 13 emits bright light after being powered on, and the light is evenly projected onto the surrounding environment through the light-emitting mirror 11. Due to the high lumen characteristics of the LED light source 13, the lighting range is wider, the light is brighter and more uniform, providing good night lighting conditions for pedestrians and vehicles.
[0035] The cooling fan 4 starts to work, and the hot air above the lamp slot 1 is extracted through the first ventilation pipeline 6 and the second ventilation pipeline 7, while the third ventilation pipeline 8 and the fourth ventilation pipeline 9 extract the air below the lamp slot 1. Due to the heat insulation board 14 provided in the ventilation pipeline, the hot air will not have too much heat impact on the LED light source 13 during the discharge process.
[0036] Due to the design of the rainproof cover 15 on the top and bottom of the housing 2, rainwater cannot enter the housing 2 even on rainy days, ensuring the dryness and safety of the LED light source 13 and electronic components. In addition, the waterproof sealing ring 16 inside the housing 2 further enhances the overall waterproof performance, allowing the street lamp to still operate stably under adverse weather conditions.
[0037] In terms of maintenance, the setting of the fixing bolts 18 makes the connection between the housing 2 and the lamp trough 1 more secure, which is convenient for later maintenance and replacement of the LED light source 13. At the same time, the design of the guide surface 17 makes it easy to put the LED light strip into the lamp trough 1, improving the convenience of installation and maintenance.
[0038] The setting of the filter screen 19 effectively prevents dust and impurities from entering the ventilation system, ensuring the unobstructed flow of the cooling fan 4 and the ventilation duct. This not only improves the stability and life of the ventilation system, but also reduces the frequency of maintenance and reduces maintenance costs.

[0040] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.
