The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral 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. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments.

[0038] The utility model provides a road lighting system. Figure 1 and Figure 2 As shown, the road lighting system includes a first road foundation 100, a supporting foundation 200, a second road foundation 300 and a street lamp foundation 400. A plurality of the supporting foundations 200 are arranged on the upper end of the first road foundation 100, and the supporting foundations 200 support the second road foundation 300. The street lamp foundations 400 are arranged on both sides of the second road foundation 300. A plurality of first street lamps 500 are installed on the street lamp foundation 400. The plurality of first street lamps 500 are respectively connected in series with a first current sensor 600 and a first variable resistor 700 and then connected in parallel to a first power supply 800. The signal output end of the first current sensor 600 is connected to the signal input end of the first controller 900, and the signal output end of the first controller 900 is connected to the signal input end of the first variable resistor 700.

[0039] Exemplarily, the second road foundation 300 adopts the standard of a traffic trunk road, with a design speed of 60 km / h, and adopts a bilaterally symmetrical lighting arrangement, with lamp poles placed on the ground on both sides of the bridge.

[0040] In specific implementation, the first current sensor 600 collects the current signal on the line of the first street lamp 500 connected in parallel with it in real time, and feeds it to the first controller 900 in real time. In this embodiment, if the first current sensor 600 cannot collect the current signal or the current signal is very small, it is considered that the first street lamp 500 on the line is faulty and cannot provide lighting normally. At this time, the first controller 900 will control the resistance of the first variable resistor 700 on the line where other first street lamps 500 adjacent to the first street lamp 500 are located. For example, when the first power supply 800 provides a constant voltage power source, reducing the resistance of the first variable resistor 700 will increase the input current of the first street lamp 500 connected in series with the first variable resistor 700, which will increase the power of the first street lamp 500, thereby increasing the power of one or more first street lamps 500 adjacent to the faulty first street lamp, and maintaining the lighting conditions of the lighting area covered by the faulty first street lamp to a certain extent.

[0041] Exemplarily, as shown in Table 1, it is a control table of the first controller when a first street lamp fails.

[0042] Table 1. Control methods

[0043]

[0044]

[0045] Please refer to Table 1. Specifically, each first street lamp is numbered. For example, when there are six first street lamps, when the controller determines that the first street lamp four is faulty according to the current signal fed by the first current sensor, the two first street lamps adjacent to the first street lamp four are numbered three and five respectively. At this time, the resistance of the first variable resistor corresponding to the first street lamp three and the first street lamp five is reduced respectively. At this time, the power of the first street lamp three and the first street lamp five will increase, and the range covered by their lighting will be increased, thereby maintaining the lighting conditions of the lighting area covered by the faulty first street lamp to a certain extent. It should be noted that the unchanged resistance of the first variable resistor in Table 1 refers to maintaining the set resistance of the first variable resistor, that is, the corresponding first street lamp works according to the set power to provide lighting. In addition, the specific change in the power of the street lamp should be determined according to the actual situation such as the spacing between street lamps and the road lighting requirements, and this embodiment is not specifically limited here.

[0046] It should be noted that if the first street lamps at the head and tail fail, such as the first street lamp one or the first street lamp six fails, then relative to the first street lamp in the middle fails, since there is only one first street lamp adjacent to it, the power adjustment of this first street lamp should be greater than adjusting the power of the two first street lamps.

[0047] In some embodiments, Figure 1As shown, a middle guardrail 1000 is disposed at the upper end of the second road foundation 300 , and the middle guardrail 1000 cooperates with the street lamp foundations 400 disposed on both sides of the second road foundation 300 to form two symmetrical lanes 1100 at the upper end of the second road foundation 300 .

[0048] In some embodiments, Figure 1 As shown, a wire collection groove 1200 is provided at the lower end of the second road foundation 300 .

[0049] The purpose of setting up the wire receiving groove 1200 is to facilitate the storage of the wiring of the first street lamp 500. At the same time, electronic components such as the first controller 900, the first current sensor 600 and / or the first variable resistor 700 can be correspondingly arranged in the wire receiving groove 1200. The wire receiving groove 1200 can also play a role in protecting the above electronic components.

[0050] In some embodiments, the supporting foundation 200 is a bridge pier.

[0051] In some embodiments, a plurality of the supporting bases 200 are arranged in an array, and the spacing between two adjacent supporting bases 200 is equal and is set to 10 to 20 m. The arrangement position of the first street lamp 500 corresponds to the position of the supporting base 200, and a first street lamp 500 is installed on each of the street lamp bases 400 arranged on both sides of the second road base 300 supported by each supporting base 200.

[0052] It should be noted that the above arrangement of the first street lamps 500 is only an example and is not a limitation of the present invention. In some embodiments, the first street lamps 500 may also be arranged according to other array standards.

[0053] In some embodiments, Figure 1 As shown, the upper end surface of the first road foundation 100 is provided with a first motor vehicle lane 101, a first side strip 102, a first non-motor vehicle lane 103, a first side walk 104, a second motor vehicle lane 105, a second side strip 106, a second non-motor vehicle lane 107 and a second side walk 108, the first side strip 102 is arranged between the first motor vehicle lane 101 and the first non-motor vehicle lane 103, the first side walk 10 is arranged on the side of the first non-motor vehicle lane 103 where the first side strip 102 is not arranged, the second side strip 106 is arranged between the second motor vehicle lane 105 and the second non-motor vehicle lane 107, and the second side walk 108 is arranged on the side of the second non-motor vehicle lane 107 where the second side strip 106 is not arranged.

[0054] The first road foundation 100 is designed as an auxiliary road, for example only, using the standard of urban secondary trunk road, with a design speed of 40km / h. The motor vehicle lane of the standard road section adopts the method of installing floodlights at the bottom of the bridge, with double rows of LED floodlights arranged. The floodlights are arranged at the position of each bridge pier, and the spacing between the piers is 15m.

[0055] In a preferred embodiment, if Figure 1 and Figure 3 As shown, a plurality of second street lamps 109 are disposed on the first sidewalk 104 and the second sidewalk 108. The plurality of second street lamps 109 are respectively connected in series with a second current sensor 110 and a second variable resistor 111 and then connected in parallel to a second power supply 112. The signal output end of the second current sensor 110 is connected to the signal input end of the second controller 113, and the signal output end of the second controller 113 is connected to the signal input end of the second variable resistor 111.

[0056] This embodiment uses different control systems for the first street lamps and the second street lamps arranged on the first road foundation 100 and the second road foundation 300, respectively, because different road properties may lead to different lighting requirements, that is, different control of the working power of the street lamps. When one of the multiple second street lamps 109 fails, the basic control principle of the second controller 113 on the second variable resistor 111 is consistent with the control principle of the first controller 900 on the first street lamp 500, which will not be elaborated in detail here.

[0057] It should be noted that the electronic components involved in this embodiment, such as the first controller 900, the first current sensor 600, the first variable resistor 700, the first power supply 800, the second current sensor 110, the second variable resistor 111, the second power supply 112, the second controller 113, etc., all use existing electronic devices. The first section element 800 and the second power supply 112 are also powered in a similar manner. For example, a distribution box can be used to access the national power grid to provide a corresponding power source. The first street lamp and the second street lamp involved in actual use will be selected differently due to different lighting conditions.

[0058] In some embodiments, the street lamp foundation 400 is a street lamp foundation formed integrally with the concrete guardrail. For details, please refer to Figure 4 and Figure 5The street lamp foundation 400 includes a concrete guardrail 401, a lamp pole column 402 and a hard plastic pipe 403. An embedded steel plate 404 is arranged on the upper part of the concrete guardrail 401. A flange 405 is installed on the embedded steel plate 404. The lamp pole column 402 is connected to the flange 405. One end of the hard plastic pipe 403 passes through the lamp pole column 402, the flange 405, the embedded steel plate 404 and the concrete guardrail 401 in sequence and is arranged on the outside of the concrete guardrail 401.

[0059] In the road lighting system, the embedded steel plate 404 is embedded in the upper part of the concrete guardrail 401, and the upper end surface of the embedded steel plate 404 is exposed to the outside of the concrete guardrail 401. For example, the upper end of the embedded steel plate 404 is flush with the upper end of the concrete guardrail 401. When the embedded steel plate 404 has been embedded, the flange 405 is installed through the embedded steel plate 404. The installation method includes but is not limited to welding. The subsequent embodiments will also provide a specific installation example of the flange 405 on the embedded steel plate 404. The flange 405 plays the role of installing the lamp post 402. The lamp post 402 can be a steel post. The lamp post 402 is used to install street lamps. In this way, this embodiment can improve the construction efficiency and ensure the bearing capacity of the concrete structure through the design of the embedded steel plate 404 and the flange 405 based on the embedded design. At the same time, the linear shape of the road lamp foundation and the guardrail foundation on the road side is consistent, so as to achieve a perfect connection between the street lamp foundation and the guardrail, which has a certain aesthetics.

[0060] This embodiment also solves the problem of street lamp wiring after installation through the design of hard plastic tube 403. The hard plastic tube 403 can protect the street lamp wiring and hide the wiring to a certain extent. One end of the hard plastic tube 403 passes through the lamp post 402, flange 405, embedded steel plate 404 and concrete guardrail 401 in sequence and is set outside the concrete guardrail 401, and the other end is set inside the street lamp post 2. Figure 2 The position of one end of the hard plastic tube 403 inside the lamp pole column 402 shown in the figure is only an example in principle, and its specific position should be determined according to the installation position of the street lamp. For example, when the street lamp is installed on the top of the lamp pole column 402, one end of the hard plastic tube 403 can be set at the top position inside the lamp pole column 402. If the street lamp is installed at the side end of the lamp pole column 402, one end of the hard plastic tube 403 can be set at a position inside the lamp pole column 402 close to the side end surface.

[0061] In this embodiment, Figure 4As shown, the second road foundation 300 includes a bridge deck pavement layer 301 and a beam flange 302, the beam flange 302 supports the concrete guardrail 401, the bridge deck pavement layer 301 is arranged at the upper end of the beam flange 302 and one side of the bridge deck pavement layer 301 is abutted against the side of the concrete guardrail 401.

[0062] It should be noted that the second road foundation 300 exemplified above is a common road foundation structure on a current viaduct road, representing a certain road scene to which the present embodiment can be applied, which is only an example and not a limitation of the present invention. For example, the present invention can also be applied to other road scenes, such as other road pavements with concrete guardrails.

[0063] In some embodiments, a specific installation structure of the embedded steel plate 404 and the flange 405 is provided, such as Figure 3 As shown, at least one embedded anchor bolt 407 is disposed in the upper inner portion of the concrete guardrail 401 , and one end of the embedded anchor bolt 407 passes through the embedded steel plate 404 to fix the flange 405 to the upper end of the embedded steel plate 7 .

[0064] In this embodiment, the embedded steel plate 404 and the embedded anchor bolts 407 are fixed by using the concrete guardrail 401, and the embedded anchor bolts 407 are used to install the flange 405, so as to ensure the installation stability of the flange 405, thereby improving the overall structural stability of the road lighting system. When the embedded anchor bolts 407 are provided in multiple numbers, the flange 405 can be further stabilized. As an example only, the embedded anchor bolts 407 are provided in four numbers.

[0065] In some embodiments, Figure 7 As shown, the lamp post column 402 is welded and fixed to the upper end of the flange 405 .

[0066] In some embodiments, Figure 8 As shown, a reinforcement member 408 is provided at the welding position between the lamp post 402 and the flange 405, and the connection stability between the lamp post 402 and the flange 405 is ensured by the provision of the reinforcement member 408. Preferably, the reinforcement member 408 is an angle steel reinforcement member, for example, a 40×40 equilateral angle steel.

[0067] In some embodiments, in order to facilitate the installation of street lamps, a street lamp mounting plate is assembled on the lamp post column 402 by means of a bolt assembly. Specifically, Figure 6 and Figure 8As shown, the lamp pole column 402 is provided with a first bolt hole 409, and also includes a connecting bolt 410 and a street light mounting plate 411 adapted to the first bolt hole 409, and the street light mounting plate 411 is provided with a second bolt hole 412 adapted to the connecting bolt 410, and the connecting bolt 410 fixes the street light mounting plate 411 to the lamp pole column 402 through the first bolt hole 409 and the second bolt hole 412.

[0068] In some embodiments, in order to improve the stability of the street lamp mounting plate 411 on the lamp post 402, as shown in FIG. Figure 3 As shown, a column cap 406 is provided at the upper end of the lamp pole column 402, and the column cap 406 is located above the street light mounting plate 411. According to actual conditions, if necessary, the column cap 406 and the street light mounting plate 13 can be welded to ensure that the street light mounting plate 13 can be stably installed on the lamp pole column 402.

[0069] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
