Description

Technical Field

[0001] The present application relates to the technical field of street lamp lighting, and in particular to an LED street lamp and a lighting component thereof. Background Art

[0002] Street lights refer to tools that provide lighting functions for roads. They generally refer to lamps within the scope of road lighting in traffic lighting. They are widely used in various places where lighting is needed. With the continuous advancement of science and technology, light-emitting diode (LED) technology has gradually matured, and LEDs with high energy efficiency and long life have become an ideal choice for street lighting.

[0003] Existing LED street lamps generate a lot of heat energy during operation. According to the electro-optical conversion efficiency of LED, which is usually 20%-40%, 60%-80% of the electrical energy will be converted into heat energy, and the temperature will rise to 85°C in about 8-10 minutes, which usually causes the diode to overheat and produce light decay. In order to solve the light decay phenomenon, most LED street lamps are equipped with cooling fans to force heat dissipation. The use of cooling fans for heat dissipation will waste a lot of electricity and cannot dissipate heat faster. Even if the street lamps in the prior art are equipped with photovoltaic panels and batteries, they still need to consume a lot of electricity. Since street lamps are used for lighting on the road, it is inevitable that some dust will adhere to the surface of the lampshade of the street lamp, such as dust on the road raised by cars or exhaust gas generated by cars, which will cause the lighting effect to be weakened, and it is necessary to manually clean it regularly, which will result in a lot of time-consuming manual work. Summary of the invention

[0004] The present application proposes an LED street lamp, which has the advantages of good lighting effect, accelerated heat dissipation, and the ability to clean surface dust, and is used to solve the problems of large power loss, slow heat dissipation, dust adhesion on the surface, and dim light.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an LED street lamp, consisting of a lamp pole, a lampshade, a water pump and a photovoltaic panel, a lamp pole base welded to the lower end of the lamp pole, an irregular water pipe is arranged inside the lamp pole, a sealing shell is installed inside the lampshade, an LED lamp board is embedded inside the sealing shell, one end of the LED lamp board is connected to the PLC control board, the upper and lower ends of the sealing shell are respectively an upper lampshade and a lower lampshade, a piston valve is arranged at the end of the lower lampshade close to the lamp pole, a water outlet is arranged at the lowest end of the piston valve, a lifting plate is arranged at the upper end of the inner wall of the upper lampshade, an electromagnetic induction block is arranged at the end of the lifting plate close to the lamp pole, a connecting line is arranged between the electromagnetic induction block and the water pump, and the water inside the water pipe is a transparent liquid with a boiling point lower than 85°C, such as a mixed liquid of alcohol and pure water.

[0006] Furthermore, a storage battery is provided under the photovoltaic panel. The photovoltaic panel converts light energy into electrical energy, and the storage battery stores the electrical energy, thereby achieving the effect of saving electrical energy.

[0007] The application of batteries and photovoltaic panels has saved a lot of electricity loss in a large number of street lamps. Since light energy is a renewable energy source, it can be converted into electrical energy to save electricity.

[0008] Furthermore, the lampshade is composed of two components, namely an upper lampshade and a lower lampshade. The interior of the upper lampshade is connected to the water inlet pipe, while the lower lampshade is connected to the water outlet pipe.

[0009] The entire lampshade is connected to the lamp pole through a fitting sleeve on the lampshade to form a circulation effect. Two water pipes are arranged inside the lamp pole, namely an inlet pipe and an outlet pipe. The water pipe at the end away from the lampshade is the inlet pipe, and the other end is the outlet pipe.

[0010] Furthermore, the sealing shell is composed of a sealing upper cover and a sealing body. The sealing body is made of a transparent material as a whole. The two are connected by screws to achieve a sealing effect. A heating groove is provided above the sealing upper cover, and a partition with a horizontal angle greater than 135° is provided inside the heating groove.

[0011] The heating tank will first heat the water inside the heating tank. Since the water vapor during the heating process will move upward, in order to push the mixed liquid inside the lampshade, the partition needs to be tilted to play a diversion effect.

[0012] Furthermore, the photovoltaic panel and the lamp pole base are welded to the lower end of the lamp pole and connected to the ground, and a water tank is provided below the lamp pole base.

[0013] Since the mixed liquid inside the lampshade is always in a completely covered state, the mixed liquid will flow from the water inlet pipe into the upper lampshade and then to the lower lampshade, then from the lower lampshade to the water outlet pipe, and finally return to the water tank to form a closed loop.

[0014] A lighting component for an LED street lamp, wherein the lamp board is composed of a plurality of semicircular lamp beads, each lamp bead contains a diode, a rectangular connecting plate connected to the diode connecting line is arranged above the lamp board, and positive and negative copper wires are arranged at one end of the connecting plate close to the lamp pole and connected to a PLC control end.

[0015] Preferably, a battery is provided under the photovoltaic panel, and the battery is used to store the electric energy generated by the photovoltaic panel. When the photovoltaic panel receives a light signal, the PLC control end controls the battery to stop supplying power to the light board, and the light board is turned off.

[0016] The beneficial effects of the present invention are as follows: This application provides an LED street lamp and a lighting assembly thereof: By circulating water around the entire lampshade, the heat energy generated by the lamp panel can be absorbed.

[0017] By circulating a mixed liquid with a boiling point lower than 85°C, the liquid in the heating tank is more easily heated to boil, thereby generating a large amount of steam to push the liquid to circulate, and no water pump is needed for circulation, thus achieving energy saving.

[0018] By filling the space between the lower lampshade and the sealing body with water, the light emitted by the lamp can be refracted to the lower lampshade, thereby achieving more focused light and better lighting effect.

[0019] A lifting plate is provided on the upper inner wall of the upper lampshade. When the internal pressure is too high, the steam will lift the lifting plate until it is connected to the electromagnetic induction plate, transmitting the current signal to the water pump, thereby accelerating the circulation of the mixed liquid.

[0020] By controlling the light board through the PLC control end, when the light board is not powered on, no heat energy will be generated. Since there is gas in the upper lampshade itself and the lifting plate is still connected to the electromagnetic induction block, the water pump will continue to work until the lifting plate falls. The internal water pressure will increase to push the piston valve under the outlet pipe, and the mixed liquid will be sprayed through the water nozzle to clean the dust remaining on the surface of the lower lampshade.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0024] like Figure 1 , Figure 2 As shown, a lamp pole base 8 is welded under the lamp pole, a water tank 9 is connected under the lamp pole base 8, a water pipe 15 is arranged inside the water tank 9, a line passes between the two water pipes 15, the water pipe 15 is connected to the inside of the water tank 9 at the same time, the water pipe 15, the water tank 9 and the lampshade 2 are all filled with mixed liquid, the lampshade 2 and the lamp pole 1 are connected through the fitting sleeve 11 at the end of the lampshade 2, and the specific position can be referred to. Figure 6 A water pump 3 is provided at the upper end of the connection between the fitting sleeve 11 and the lamp pole 1, and the interior of the water pump 3 is embedded in the interior of the lamp pole 1; a battery 7 is provided below the photovoltaic panel 6, and the photovoltaic panel 6 and the battery 7 are simultaneously arranged at the top of the lamp pole 1. Example

[0025] like Figure 3-Figure 5 As shown, one end of the lamp board 13 is connected to the top of the PLC control terminal 10 through the positive and negative copper wires 18. The PLC control terminal 10 is used to control the closing and opening of the lamp beads 131 inside the lamp board 13. When the photovoltaic panel 6 receives the light signal, it starts to charge the battery 7, and the PLC control terminal 10 will cut off the power to the lamp board 13, and the lamp board 13 will no longer light up.

[0026] Several lamp beads 131 are installed inside the lamp board 13. The inside of the lamp beads 131 is a diode (LED). A connecting plate 17 is provided above the diode (LED) inside the lamp beads 131. There are two connecting plates 17 above each group of diodes (LED). One connecting plate 17 is only connected to the positive pole, and the other is connected to the negative pole. A sealing shell 14 is provided outside the lamp board 13. The sealing shell 14 is divided into a sealing shell upper cover 141 and a sealing body 142. The sealing body 142 is made of transparent material as a whole to ensure the penetration of the lamp beads 131 lighting. A heating groove 16 is neatly arranged above the sealing shell 14. The bottom of the heating groove 16 is in direct contact with the heat source of the lamp board 13. Since the mixed liquid fills the entire lampshade 2, the heating groove 16 will heat the water inside the lampshade 2. Since the steam will only gush vertically upward, a partition greater than 135° compared to the horizontal direction is provided in the heating groove 16 to guide the heated steam. Example

[0027] like Figure 6 As shown, the heating groove 16 at the upper end of the sealed shell 14 heats the mixed liquid above the sealed shell 14. Since the bottom of the heating groove 16 is in close contact with the heat source of the lamp board 13, the mixed liquid in the heating groove 16 is more likely to reach the boiling point. When the water in the heating groove 16 boils, a large amount of steam will be generated. The steam in the heating groove 16 will be guided by the partition in the heating groove 16, thereby pushing the mixed liquid above the sealed shell 14 to the bottom of the sealed shell 14.

[0028] A lifting plate 19 is provided above the upper lampshade 21 above the sealing shell 14. When the heating tank 16 heats the mixed liquid, steam is generated. The steam will lift the lifting plate 19 to the highest point of the lifting plate 19. An electromagnetic induction block 41 is provided on the outer wall of the highest point of the lifting plate 19, which will transmit the electromagnetic signal to the water pump 3 through the connecting line 4. The water pump 3 starts to work to accelerate the circulation of the mixed liquid inside the water inlet pipe 15. The steam drives the mixed liquid to circulate slowly. The water pump 3 is used to accelerate the circulation of the mixed liquid.

[0029] Since the entire sealing shell 14 is coated with the mixed liquid inside, there will also be a mixed liquid between the lower lampshade 22 and the sealing shell 14. At this time, the mixed liquid between the lower lampshade 22 and the sealing shell 14 will form a standard convex lens with the lower lampshade 22. When the light passes through the mixed liquid and then through the lower lampshade 22, according to the principle of light refraction, a focusing effect will be formed, which will make the light more focused and brighter.

[0030] When the PLC control end 10 is turned off, the lamp board 13 will also be turned off. There is a line connection between the PLC control end 10 and the water pump 3. There is a delay circuit in the PLC control end 10 for controlling the delayed shutdown of the water pump 3. At this time, the delayed shutdown water pump 3 will bring in new mixed liquid, and the pressure inside the lampshade 2 will increase due to the action of the water pump 3. In order to release the internal pressure, a piston valve 12 is provided at the end of the lower lampshade 22 that is close to the lamp pole 1. A spring is sleeved at the rear of the piston valve 12. At this time, the water pressure will push the piston valve 12 to deflect backward, and a water nozzle 5 is provided below the piston valve 12. The mixed liquid will be sprayed out from the water nozzle 5 to release the pressure, so as to achieve the effect of cleaning the dust on the surface of the lower lampshade 22.

[0031] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
