Description

Technical Field

[0001] This application relates to the field of streetlights, specifically to an integrated solar LED streetlight. Background Technology

[0002] Solar-powered LED streetlights have become one of the most commonly used streetlights in recent years. Different designs are available to suit various applications. For example, streetlights on main roads prioritize illumination, while those in residential areas, parks, and public squares often prioritize aesthetics over lighting. These streetlights typically have a striking appearance when newly installed, but high maintenance costs and the lack of access to aerial work platforms make maintenance difficult and often untimely. While the initial lighting effect is excellent, over time, dust accumulates on the lampshades, causing dim lighting and an aged look, diminishing the decorative effect. Regularly cleaning the lampshades is prohibitively expensive, and the frequency of maintenance varies across regions, making standardized management and regulations difficult. Summary of the Invention

[0007] Furthermore, a transparent cylindrical outer protective ring is installed inside the light-transmitting plate, and a transparent cylindrical inner protective ring is installed inside the outer protective ring. The inner side of the light-transmitting plate has a first strip-shaped limiting rib, the outer side of the outer protective ring has a first strip-shaped limiting groove that cooperates with the first strip-shaped limiting rib, and the inner side has a second strip-shaped limiting rib.

The end of the inner protective ring is fixed with a plurality of first protrusions that are evenly distributed in a ring, and the end of the outer protective ring is fixed with a plurality of second protrusions that are evenly distributed in a ring. The diameter of the first circular hole in the side lighting unit is smaller than the diameter of the second circular hole, and the diameter of the first circular hole is smaller than the inner diameter of the light-transmitting plate, thereby forming an annular convex edge surrounding the first circular hole at the front plate. The annular convex edge has multiple first notches and multiple second notches distributed at equal intervals in a ring. The number of first notches is equal to the number of first protrusions, and the number of second notches is equal to the number of second protrusions. Two first motors are installed on the top plate of the lifting box, and two first bearings are installed on the bottom plate. The two first motors and two first bearings correspond one-to-one. Between the corresponding first motors and first bearings... The lifting box is connected to a first lead screw, and each of its two side plates has a second vertical guide rail on its inner side.

One end of the second drive plate is hinged to the movable plate, and the other end is hinged to the first drive plate. The abutment block is capable of engaging the first and second protrusions. A mounting vertical plate connects the two side plates of the lifting box. The mounting vertical plate has multiple loading units, the number of which is equal to the number of side lighting units. Each loading unit includes a circular through hole located at the mounting vertical plate and a cylindrical loading ring fixed to the mounting vertical plate. The loading ring has a third strip-shaped limiting groove that engages with the third strip-shaped limiting rib.

[0008] Furthermore, the number of loading rings at the mounting plate is equal to the number of circular through holes, and the two correspond one-to-one.

[0009] Furthermore, the length of the first protective ring along its axis is equal to the length of the second protective ring along its axis.

[0012] Furthermore, the ends of both the first protrusion and the second protrusion are semi-circular.

[0013] Furthermore, the radial length of the second protrusion is greater than the radial length of the first protrusion.

[0014] Furthermore, the abutting block can abut against both ends of the first protrusion (i.e., the surface near the lifting box and the surface away from the lifting box); the abutting block can abut against both ends of the second protrusion (i.e., the surface near the lifting box and the surface away from the lifting box).

[0016] The chamfer makes it easier to connect the inner and outer protective rings and the loading ring, allowing for smooth connection even with a certain degree of error.

[0017] Furthermore, the first, second, and third strip-shaped limiting ribs are all fixed with adhesive.

[0018] In some embodiments, to increase the rigidity of the first, second, and third locating ribs, each rib is made of a metal rod and a rubber sleeve surrounding the metal rod. Preferably, the metal rod is in the shape of a semi-circular annular cylinder.

[0019] Furthermore, the loading unit also includes two through holes located at the mounting vertical plate, and the rear plate also has multiple sets of positioning units.

[0021] Furthermore, the front plate of the lamp post has a first replacement through hole, and the rear plate has a second replacement through hole corresponding to the position of the first replacement through hole. The first replacement through hole also has a circular sealing plate that closes the first replacement through hole.

[0022] Furthermore, the control unit is installed inside the battery box.

[0023] Furthermore, the lamp holder has a drainage groove located between the battery box and the lamp post.

[0025] Furthermore, the first, second, and third strip-shaped limiting ribs and the first, second, and third strip-shaped limiting grooves are all parallel to the axis of the light-transmitting plate.

[0026] Furthermore, the specifications of the first, second, and third strip-shaped limiting ribs and the first, second, and third strip-shaped limiting grooves are configured such that when both the inner and outer protective rings are installed at the lamp post, the outer protective ring remains stationary at the lamp post when the driving unit drives the inner protective ring to move towards the loading ring; and when both the inner and outer protective rings are located at the loading ring, the inner protective ring remains stationary at the loading ring when the driving unit drives the outer protective ring to move towards the lamp post.

[0027] Furthermore, the radii of the cross sections of the first, second, and third strip-shaped limiting grooves are equal; the radii of the cross sections of the first and third strip-shaped limiting ribs are equal, and the radius of the cross section of the first strip-shaped limiting rib is greater than the radius of the cross section of the second strip-shaped limiting rib.

[0030] Therefore, the friction between the light-transmitting plate and the outer protective ring, and the friction between the loading ring and the inner protective ring are significantly different from the friction between the inner and outer protective rings, thus further preventing the inner and outer protective rings from being accidentally moved.

[0031] Furthermore, the annular convex edge has three first notches and three second notches.

[0032] Furthermore, the adjacent first and second gaps are spaced 60 degrees apart.

[0033] Furthermore, the drive unit includes three first drive boards and three second drive boards.

[0044] Furthermore, when the lifting box is in its lowest position, the lifting box blocks the second replacement through hole.

[0045] Furthermore, the first and second replacement through holes are used to remove the outer protective ring and the inner protective ring from the loading ring.

[0046] This allows for the removal and replacement of new inner and outer protective rings.

[0047] Furthermore, the solar panel is a thin-film solar panel.

[0048] This allows for power generation even under low light conditions.

[0049] Furthermore, the lamp holder has bolt fixing holes.

The diameter of the first circular hole of the side lighting unit is smaller than the diameter of the second circular hole, and the diameter of the first circular hole is smaller than the inner diameter of the light-transmitting plate, thereby forming an annular convex edge surrounding the first circular hole at the front plate. The lifting box has multiple annularly spaced notches, the number of which equals the number of protrusions. Two first motors are installed on the top plate of the lifting box, and two first bearings are installed on the bottom plate. Each first motor and bearing corresponds to a first lead screw.

[0060] Beneficial effects: The street light of this application has the following advantages over existing street lights:

[0061] 1) Due to the use of thin-film solar panels, it can generate electricity effectively even in low-light conditions. The solar panels and batteries are located in a low position for easy maintenance. It is particularly suitable for installation on lawns along roadsides, with the lifting box located behind the streetlight.

[0062] 2) The decorative light sources are arranged in a row, with multiple light-transmitting panels in a ring shape, creating a unique decorative effect. Due to their low power, they can meet the power supply requirements without the need for large solar panels that extend outwards.

[0063] 3) The light-transmitting plate has a protective ring, so even if the protective ring is contaminated, the light-transmitting plate remains clean.

[0089] As shown in the figure, the street light of this application is mainly used in squares, parks, residential areas, and other places where brightness requirements are not high but decorative requirements are high. Besides the top LED light source for illumination, the main function of this street light is the multiple circular side lighting sources on the pole, which serve a decorative purpose. The figure shows four side lighting units, but more can be added as needed. Because the protective rings at higher positions accumulate dust after a period of use, maintenance personnel periodically replace the protective rings at each side lighting unit using a lifting box and new protective rings. The specific replacement process is shown in the figure. With the cooperation of the lifting unit, translation unit, rotation unit, and drive unit, three abutment blocks can rotate, translate, lift, and retract, thereby abutting three protruding blocks and pulling the protective rings back to the loading rings. After all the protective rings are pulled back to the loading rings, the circular sealing plate is opened, and each loading ring faces the first and second replacement rings, allowing the old protective rings to be manually removed and the loading rings to be cleaned. Then, the clean protective rings are installed at the loading rings, and the circular sealing plate is closed. Next, the lifting box can use three abutting blocks to abut against the side of the protruding block closest to the lifting box, thereby pushing the protective ring to the light-transmitting plate. The annular protrusion at the front plate can limit the movement of the protective ring, and the notch at the annular protrusion can facilitate the abutting blocks to abut against the protruding block at the protective ring.

[0090] The lifting mechanism of the lifting box is achieved through top and bottom electric winding devices. By coordinating the identification unit and positioning marks, and through precise control of these devices, the height of the lifting box can be controlled. Before each operation, the electric push rod extends into the positioning blind hole (a frustoconical hole that allows for proper positioning even with slight height errors; tightening the upper and lower pull ropes after positioning further calibrates the position). This ensures precise positioning at various heights (corresponding to the positions of the side lighting units), facilitating operation. Furthermore, the strip-shaped limiting ribs are made of rubber. The strip-shaped limiting ribs and grooves provide both positioning and friction. Due to the lightweight nature of the protective ring, it is surrounded by the light-transmitting plate and, under the influence of friction, prevents accidental detachment.

[0095] The main difference between Example 2 and Example 1 is that the light-transmitting plate has two protective rings, an inner protective ring and an outer protective ring. The inner protective ring is fitted inside the outer protective ring. After a period of use, the inner protective ring can be moved to the loading ring using the drive unit. At this time, maintenance personnel do not need to replace it immediately because the outer protective ring is still at the light-transmitting plate, preventing dust contamination. The inner and outer protective rings can be replaced only after the outer protective ring is also contaminated with dust, allowing for a longer interval between maintenance and thus lower maintenance costs. Furthermore, the radii of the first and third strip-shaped limiting ribs are equal and larger than the radius of the second strip-shaped limiting rib. This results in greater friction between the inner and loading rings, and between the outer protective ring and the light-transmitting plate. Compared to the movement between the inner and outer protective rings, the drive unit will not pull the inner protective ring out when moving the outer protective ring, or vice versa. In addition, when replacing, replace all inner and outer protective rings with clean inner protective rings.

[0096] In addition, before each replacement, all inner and outer protective rings are moved to the loading ring, and then the laser emitter and light intensity detector are activated to detect the light intensity and determine the degree of contamination. If the degree of contamination is heavy, the maintenance cycle can be shortened next time; if the degree of contamination is light, the maintenance cycle can be extended next time. This allows for more suitable maintenance based on different locations (where the degree of contamination will vary).

[0097] In some embodiments, a fan unit can be installed on the top plate of the lifting box, and ventilation holes can be provided on the back plate of the lifting box. This allows the fan to periodically lift and blow the inner and outer protective rings of each side lighting unit, thereby removing debris, dust, etc., which can further extend the maintenance cycle and further reduce maintenance costs.

[0098] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
