An energy-saving lighting device for urban roads

Abstract

This invention relates to the field of lighting technology, and more particularly to an energy-saving lighting device for urban roads. It includes a housing mounted on a lamp holder, with an energy-saving lamp housed within the housing. The lamp holder is rotatably connected to a hollow rotating shaft; the hollow rotating shaft has a limiting part; a first flexible block is fixedly connected to the housing; a second flexible block, rotatably connected to the lamp holder, is fixedly connected to the side of the housing away from the hollow rotating shaft; a sliding frame is slidably connected to the lamp holder; the housing is used to compress the sliding frame; and a buffer airbag is fixedly connected to the lamp holder. This invention changes the existing fixed-installation housing to a movable installation, allowing the housing to be cushioned by the deformation of the first flexible block, the second flexible block, and the buffer airbag when subjected to impact. This reduces the probability of the housing surface cracking due to impact from strong winds and their carried impurities, thereby increasing the upper limit of the impact the housing can withstand and improving its damage resistance.

Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to an energy-saving lighting device for urban roads. Background Technology

[0002] Energy-saving lighting equipment can help cities achieve emission reduction goals and reduce long-term operating costs by reducing energy consumption, carbon emissions, and maintenance frequency. Energy-saving lighting equipment for urban roads plays an important role in ensuring nighttime traffic safety. Traditional road lighting equipment usually adopts a fixed lamp holder structure. The housing of the lighting equipment is mostly made of glass, acrylic sheet, or plastic. The housing is exposed to complex environments for a long time and is subject to impacts from external forces such as strong winds, dust, and rain. Strong winds and the impurities they carry (such as sand and gravel) can wear down the surface of the housing and even cause the housing to crack due to impact. Once the housing is broken, the energy-saving lamp inside will come into direct contact with the external environment, which will increase the probability of damage to the energy-saving lamp, thereby affecting the lighting effect of the internal energy-saving lamp, and thus increasing the maintenance frequency and cost. Summary of the Invention

[0003] In order to overcome the shortcomings pointed out in the background art above, the present invention provides an energy-saving lighting device for urban roads.

[0004] The technical solution is: an energy-saving lighting device for urban roads, comprising a housing mounted on a lamp holder, an energy-saving lamp disposed inside the housing, and a hollow rotating shaft rotatably connected to the lamp holder near the housing;

[0005] The hollow rotating shaft is provided with a limiting part, and the housing is fixedly connected to a first flexible block. The first flexible block is used to limit the limiting part. The side of the housing away from the hollow rotating shaft is fixedly connected to a second flexible block that is rotatably connected to the lamp holder.

[0006] The lamp holder is slidably connected to a sliding frame, the housing is used to compress the sliding frame, the lamp holder is fixedly connected to a buffer airbag, the sliding frame is located between the housing and the buffer airbag, the sliding frame is used to compress the buffer airbag, an elastic element is fixedly connected between the sliding frame and the lamp holder, and the elastic coefficient of the buffer airbag is greater than the elastic coefficient of the elastic element between the sliding frame and the housing.

[0007] Furthermore, the contact point between the housing and the sliding frame is located at its edge.

[0008] Furthermore, an inner liner is fixedly connected inside the shell, and a cavity is provided between the inner liner and the shell.

[0009] Furthermore, a power component is installed inside the lamp holder, which is used to drive the hollow rotating shaft to rotate.

[0010] Furthermore, a pressure sensor is installed on the lamp holder near the air cushion, and the sliding frame is used to squeeze the pressure sensor, with a distance between the pressure sensor and the sliding frame.

[0011] Furthermore, the buffer airbag and the chamber are connected by a connecting pipe.

[0012] Furthermore, the first flexible block is an inflatable airbag, the chamber is connected to the interior of the first flexible block, and there is a gap between the second flexible block and the lamp holder, which is connected to the connecting pipe.

[0013] Furthermore, a rotating shaft is rotatably connected inside the hollow rotating shaft, the rotating shaft is detachably connected to the lamp holder, the rotating shaft is rotatably connected to the energy-saving lamp, and a torsion spring is fixed between the rotating shaft and the energy-saving lamp.

[0014] Furthermore, two scrapers and two cleaning blocks are fixedly attached to the lamp holder. Both the scrapers and the cleaning blocks are in contact with the surface of the housing, and the cleaning blocks are made of elastic material.

[0015] Furthermore, the elastic coefficient of the cleaning block is less than that of the buffer airbag.

[0016] The beneficial effects of the present invention are as follows: 1. The present invention changes the existing shell from a fixed installation to a movable installation, so that when the shell is subjected to impact, the deformation of the first flexible block, the second flexible block and the buffer airbag can buffer the movement of the shell, reduce the probability of the shell surface cracking due to the impact of strong wind and its carried impurities, thereby increasing the upper limit of the impact that the shell can withstand, and thus improving the damage resistance of the shell.

[0017] 2. By periodically rotating the housing, the clear and unclear surfaces on the housing are continuously replaced to reduce the impact of unclear housing surfaces on the lighting effect of the energy-saving lamps. During the rotation of the housing, scrapers and cleaning blocks scrape away dry impurities and wipe away wet impurities on the housing surface, respectively, to maintain the clarity of the housing. When the housing moves due to strong winds, both the first and second flexible blocks expand actively, clamping the limiting part of the hollow rotating shaft to enhance the stability of the housing and reduce the shaking amplitude, ensuring the stability of the lighting of this device. After the housing is damaged, it automatically rotates 180° to rotate the damaged part of the housing into the lamp holder, thereby reducing the impact of housing damage on the lighting effect of the internal energy-saving lamps.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] This embodiment discloses an energy-saving lighting device for urban roads, which is used for lighting urban roads and improves the upper limit of the impact that the lighting device housing can withstand by buffering, thereby reducing the probability of housing damage.

[0030] like Figures 1-7As shown, the lamp holder 1 includes a housing 2, which is mounted on the lamp stand 1. The lamp stand 1 is equipped with a control terminal (not shown) and a solar panel. The housing 2 is made of a transparent material, such as acrylic. An energy-saving lamp 201, electrically connected to the control terminal, is installed inside the housing 2. A hollow rotating shaft 3 is rotatably connected to the lamp stand 1 near the housing 2. The circuit wires of the energy-saving lamp 201 pass through the hollow rotating shaft 3 to the outside of the housing 2. The hollow rotating shaft 3 is provided with a limiting part 4. A first flexible block 5 is fixed to the front side of the housing 2. The first flexible block 5 is used to limit the limiting part 4. When the hollow rotating shaft 3 drives the limiting part 4 to rotate, the limiting part 4 drives the first flexible block 5 to rotate. A second flexible block 6 is fixed to the rear side of the housing 2 and rotatably connected to the lamp stand 1. The torsional resistance of the first flexible block 5 is higher than its compressive resistance, and the torsional resistance of the second flexible block 6 is higher than its compressive resistance. When the housing 2 is impacted and moves laterally, the housing 2 compresses the first flexible block 5 and the second flexible block 6. The first flexible block 5 and the second flexible block 6 are compressed and deformed. The housing 2, hollow rotating shaft 3, limiting part 4, the first flexible block 5 and the second flexible block 6 can all be removed from the lamp holder 1. The lamp holder 1 is slidably connected to the sliding frame 7. The housing 2 is used to compress the sliding frame 7. The lamp holder 1 is fixedly connected to the buffer airbag 8. The sliding frame 7 is located between the housing 2 and the buffer airbag 8. The sliding frame 7 is used to compress the buffer airbag 8. An elastic element is fixedly connected between the sliding frame 7 and the lamp holder 1. The elastic element between the sliding frame 7 and the lamp holder 1 is a tension spring. The elastic coefficient of the buffer airbag 8 is greater than the elastic coefficient of the elastic element between the sliding frame 7 and the housing 2. When the buffer airbag 8 initially expands, the elastic element between the sliding frame 7 and the housing 2 supports the sliding frame 7 so that the buffer airbag 8 remains in an expanded state. The contact point between the housing 2 and the sliding frame 7 is located at the front and rear edges. The thickness of the front and rear edges of the housing 2 is greater than that of the rest of the housing 2 to reduce the probability of the housing 2 being damaged by pressure.

[0031] Initially:

[0032] The airbag 8 is inflated, and the elastic element between the sliding frame 7 and the lamp holder 1 is stretched and stored.

[0033] During use:

[0034] When this device is needed for lighting, the energy-saving lamp 201 is turned on via the control terminal. During the lighting process, if the external environment is windy, the wind will impact the housing 2, and may even carry impurities that impact the surface of the housing 2. When the wind impacts the right side of the housing 2, the housing 2 moves to the left due to the impact of the wind. The housing 2 compresses the first flexible block 5 and the second flexible block 6, causing the first flexible block 5 and the second flexible block 6 to deform. At the same time, the housing 2 compresses the sliding frame 7, and the sliding frame 7 compresses the buffer airbag 8, causing the buffer airbag 8 to deform as well. The elastic element between the sliding frame 7 and the lamp holder 1 contracts. Through the deformation of the first flexible block 5, the second flexible block 6 and the buffer airbag 8, the movement of the housing 2 is buffered, reducing the probability of the surface of the housing 2 breaking due to the impact of the wind and its carried impurities, thereby increasing the upper limit of the impact that the housing 2 can withstand, and thus improving the damage resistance of the housing 2.

[0035] When it is necessary to stop using this device, turn off the energy-saving lamp 201 through the control terminal. If the energy-saving lamp 201 needs to be replaced, the operator removes the housing 2, hollow rotating shaft 3, limiting part 4, first flexible block 5 and second flexible block 6, then pulls out the hollow rotating shaft 3, limiting part 4 and first flexible block 5 forward, replaces the energy-saving lamp 201 inside the housing 2, and finally reinstalls the housing 2, hollow rotating shaft 3, limiting part 4, first flexible block 5 and second flexible block 6.

[0036] Example 2

[0037] This embodiment discloses an energy-saving lighting device for urban roads. Based on embodiment 1, it also has the function of automatically detecting and replacing the damaged surface of the housing 2.

[0038] like Figure 6 and Figure 7 As shown, an inner liner 9 is fixedly connected inside the shell 2, and a cavity 901 is provided between the inner liner 9 and the shell 2. The material of the inner liner 9 is the same as that of the shell 2. Through the double-layer structure of the inner liner 9 and the shell 2 and the cavity 901 between them, the energy-saving lamp 201 inside the shell 2 is protected in multiple layers.

[0039] like Figure 3 and Figure 4 As shown, a power component 10 is installed inside the lamp holder 1. The power component 10 can be composed of a motor and a gear set. The gear set consists of two spur gears. One spur gear is fixedly connected to the output shaft of the motor, and the other spur gear is fixedly connected to the hollow rotating shaft 3. The motor of the power component 10 is electrically connected to the control terminal. The power component 10 is used to drive the hollow rotating shaft 3 to rotate. The left half of the housing 2 is located inside the lamp holder 1. Since the torsional resistance of the first flexible block 5 is higher than its compressive resistance, the first flexible block 5 does not deform when the limiting part 4 drives the first flexible block 5 to rotate.

[0040] like Figure 6 and Figure 7 As shown, a pressure sensor 11 is installed near the airbag 8 on the lamp holder 1. The pressure sensor 11 is electrically connected to the control terminal. The sliding frame 7 is used to squeeze the pressure sensor 11. There is a distance between the pressure sensor 11 and the sliding frame 7. After the pressure sensor 11 is compressed, the power component 10 is controlled by the control terminal to drive the hollow rotating shaft 3 to rotate 180°.

[0041] like Figure 7 As shown, the buffer airbag 8 and the chamber 901 are connected by a connecting pipe 12. Initially, the buffer airbag 8 is in an inflated state. When the shell 2 is damaged, the gas in the chamber 901 leaks out, causing the gas in the buffer airbag 8 to leak out into the chamber 901 through the connecting pipe 12.

[0042] like Figure 7 As shown, the first flexible block 5 is an inflatable airbag, and the chamber 901 is connected to the interior of the first flexible block 5. There is a gap between the second flexible block 6 and the lamp holder 1. This gap is connected to the connecting pipe 12. When the buffer airbag 8 is compressed, the gas in the buffer airbag 8 enters the interior of the first flexible block 5 and the gap between the second flexible block 6 and the lamp holder 1 through the connecting pipe 12 and the chamber 901.

[0043] The working process of this embodiment follows that of Embodiment 1, and is described in detail as follows:

[0044] During the use of this device, when the right side of the housing 2 becomes contaminated with impurities (such as dust and mud) or scratched (due to sand particles carried by strong winds abrading the surface of the housing 2), resulting in an unclear right side of the housing 2, the power component 10 drives the hollow rotating shaft 3 to rotate 180° (by pre-setting a program, the control terminal periodically turns on the power component 10, causing the power component 10 to periodically drive the hollow rotating shaft 3 to rotate 180°). The hollow rotating shaft 3 drives the first flexible block 5 to rotate through the limiting part 4, and the first flexible block 5 drives the housing 2 to rotate. The housing 2 rotates 180°, causing the side of the housing 2 covered with impurities to rotate into the lamp holder 1. The control terminal turns off the power component 10. After impurities adhere to the right side of the housing 2 or scratches are generated, a part of the housing 2 hidden inside the lamp holder 1 is rotated to the outside of the lamp holder 1, that is, a clear part of the housing 2 is rotated to the outside of the lamp holder 1 to ensure the lighting effect of the energy-saving lamp 201.

[0045] When the housing 2 moves to the left due to the impact of a strong wind, the housing 2 compresses the first flexible block 5 and the second flexible block 6, causing the first flexible block 5 and the second flexible block 6 to deform. At the same time, the housing 2 compresses the sliding frame 7, and the sliding frame 7 compresses the buffer airbag 8, causing the buffer airbag 8 to also deform. The elastic element between the sliding frame 7 and the housing 2 contracts, and the gas in the buffer airbag 8 enters the interior of the first flexible block 5 and the gap between the second flexible block 6 and the lamp holder 1 through the connecting pipe 12 and the chamber 901, causing the first flexible block 5 and the second flexible block 6 to expand. The first flexible block 5 and the second flexible block 6 clamp the limiting part 4 of the hollow rotating shaft 3, enhancing the stability of the housing 2, reducing the shaking amplitude of the housing 2, and ensuring the stability of the lighting of this device.

[0046] When the housing 2 is damaged, for example, due to prolonged exposure to strong winds, the housing 2 is worn down by sand particles carried by the wind and impacted by impurities, causing the housing 2 to break. The gas in the chamber 901 will leak to the outside. The gas in the buffer airbag 8 will leak out into the chamber 901 through the connecting pipe 12. The buffer airbag 8 will no longer inflate. The elastic element between the sliding frame 7 and the housing 2 will be compressed. The sliding frame 7 will squeeze the pressure sensor 11. The pressure sensor 11 will be compressed and will activate the power component 10 through the control terminal. The power component 10 will drive the hollow rotating shaft 3 to rotate 180°. The above steps will be repeated to rotate the housing 2 180°, rotating the damaged part on the housing 2 into the lamp holder 1 to reduce the impact of the damage to the housing 2 on the lighting effect of the internal energy-saving lamp 201. After the power component 10 drives the hollow rotating shaft 3 to rotate 180°, the control terminal will turn off the power component 10.

[0047] Example 3

[0048] This embodiment discloses an energy-saving lighting device for urban roads, which is a further improvement on embodiment 2.

[0049] like Figure 7 and Figure 8 As shown, a rotating shaft 13 is rotatably connected inside the hollow rotating shaft 3. The rotating shaft 13 is detachably connected to the lamp holder 1 and rotatably connected to the energy-saving lamp 201. A torsion spring is fixed between the rotating shaft 13 and the energy-saving lamp 201. The torsion spring supports the energy-saving lamp 201 to overcome its own weight. If the energy-saving lamp 201 is directly impacted by strong winds or even by impurities carried by the wind after the shell 2 and inner liner 9 are damaged, the energy-saving lamp 201 will rotate. The torsion spring between the rotating shaft 13 and the energy-saving lamp 201 will store energy. After the strong wind stops, the torsion spring between the rotating shaft 13 and the energy-saving lamp 201 will reset, allowing the energy-saving lamp 201 to rotate back to its original position. This buffers the impact on the energy-saving lamp 201 and reduces the probability of the energy-saving lamp 201 being damaged by impact.

[0050] Example 4

[0051] This embodiment discloses an energy-saving lighting device for urban roads, which is a further improvement on embodiment 2.

[0052] like Figures 3-5 As shown, two scrapers 15 and two cleaning blocks 16 are fixed to the lamp holder 1. Both the scrapers 15 and the cleaning blocks 16 are in contact with the surface of the housing 2. The cleaning blocks 16 are initially in a charged state to adhere tightly to the surface of the housing 2. The cleaning blocks 16 are located inside the lamp holder 1, and the scrapers 15 are located outside the lamp holder 1. The cleaning blocks 16 are made of elastic material. During the rotation of the housing 2, the scrapers 15 and the cleaning blocks 16 scrape and wipe away impurities on the surface of the housing 2, respectively. Dry impurities are scraped off by the scrapers 15, and impurities containing moisture are wiped away by the cleaning blocks 16. At the same time, dry and wet impurities are cleaned to maintain the clarity of the housing 2. The elastic coefficient of the cleaning blocks 16 is less than that of the buffer airbag 8, so that the cleaning blocks 16 adhere tightly to the housing 2. However, due to the support of the buffer airbag 8 and the sliding frame 7, the housing 2 will not move to the left.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
