Description

Technical Field

[0001] This utility model relates to the field of smart street light technology, specifically to a sensor-type smart urban street light. Background Technology

[0002] Induction-sensor smart streetlights are intelligent lighting systems that integrate sensors. Through light sensors, they perceive environmental changes in real time and automatically adjust brightness and on / off status to achieve energy-saving effects such as "lights on when people are present, lights off when people leave." Their advantages include reduced energy consumption (energy savings of over 60%), reduced light pollution, extended lamp life, and the ability to optimize urban lighting management through big data, promoting green and low-carbon development.

[0003] Most existing sensor-operated smart streetlights have their lamp holders installed inside the lamp housing. However, in order to improve the waterproofness and sealing of the lamp housing, the lamp housing is mostly sealed. This makes it inconvenient for the lamp holder to be disassembled, maintained, and replaced. In addition, the sealed lamp housing has poor heat dissipation, and the smart streetlights are prone to failure due to high temperature. Therefore, based on actual usage, we have improved the above-mentioned existing technology. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sensor-operated smart street light includes a light pole with a lamp housing and a photovoltaic module mounted on it. A mounting cover is installed on the inner wall of the lamp housing, and a PLC controller is installed on the outer wall of the mounting cover. A brightness sensor is installed on the front face of the lamp housing. A heat dissipation structure is provided inside the mounting cover, and through holes are opened at the bottom of both sides of the mounting cover. LED lamp holders are installed between adjacent through holes, and slots connecting the through holes are opened on both sides of the LED lamp holders. U-shaped seats are installed on both outer sides of the mounting cover, and locking blocks with fixing slots are installed inside the U-shaped seats. A magnetically connected transparent base plate is provided at the bottom of the mounting cover, and heat dissipation vents are opened on both sides of the mounting cover.

[0008] Furthermore, the heat dissipation structure includes a cooling fan connected to the inner cavity of the fixed cover via a bracket, multiple sets of heat dissipation fins on the side of the LED lamp holder near the cooling fan, and heat exhaust pipes connected to the heat dissipation vents installed on both sides of the fixed cover.

[0009] Furthermore: a movable rod is slidably connected inside the U-shaped base. The end of the movable rod near the LED lamp holder is connected to the locking block. A sliding plate is installed on the outer wall of the movable rod, and a compression spring is also fitted on the outer wall of the movable rod. The compression spring is located between the outer side of the sliding plate and the inner wall of the U-shaped base.

[0010] Furthermore: both outer walls of the transparent base plate are equipped with magnets, and both inner walls of the fixing cover are equipped with iron plates that are magnetically connected to the magnets.

[0011] Furthermore, the inner walls of both sets of heat dissipation vents are equipped with dustproof mesh, and the dustproof mesh is connected to the heat dissipation vents by a snap-fit ​​method.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a brightness sensor to detect the brightness of the external environment in real time and feeds the results back to the PLC controller. The PLC controller then controls the brightness of the LED lamp holder. The smart street light can automatically sense the ambient brightness and adjust its brightness accordingly, thus saving energy. The transparent base plate and the fixed cover are magnetically connected. The sliding of the moving rod inside the U-shaped base moves the sliding plate. Combined with the action of the compression spring, the locking block can connect or disconnect from the slot, enabling quick assembly and disassembly of the LED lamp holder and the fixed cover, facilitating future maintenance and replacement. The cooling fan generates suction, and the heat generated by the LED lamp holder during operation is dissipated through the heat pipe and heat dissipation vent, achieving rapid heat dissipation for the smart street light and extending its service life.

[0025] Example 1:

[0026] Please see Figure 1-3This utility model provides a technical solution: an induction-type smart street light for cities, including a light pole 1, a light housing 3 and a photovoltaic module 2 on the light pole 1, a fixing cover 5 installed on the inner wall of the light housing 3, a PLC controller installed on the outer wall of the fixing cover 5, a brightness sensor 4 installed on the front end of the light housing 3, a heat dissipation structure inside the fixing cover 5, and through holes 15 opened at the bottom of both sides of the fixing cover 5, LED lamp holders 9 are provided between adjacent through holes 15, and slots 14 connecting the through holes 15 are opened on both sides of the LED lamp holders 9, U-shaped seats 16 are installed on both sides of the outer walls of the fixing cover 5, and a locking block 20 for fixing the slots 14 is provided in the U-shaped seats 16, a transparent base plate 11 magnetically connected to the bottom of the fixing cover 5, and heat dissipation vents 8 are opened on both sides of the fixing cover 5.

[0027] The smart streetlights and photovoltaic modules 2 are existing equipment, and their specific structures and working principles will not be described here. The start / stop and brightness of the LED lamp holder 9 are controlled by the PLC controller. The electrical terminals of each electrical device are electrically connected to the PLC controller and the external power supply via wires. The brightness sensor 4 can detect the brightness of the external environment in real time and feed the detection results back to the PLC controller in real time. The PLC controller controls the brightness of the LED lamp holder 9. The smart streetlight can automatically sense the external brightness and adjust the brightness, which plays an energy-saving role. Through the magnetic connection between the transparent base plate 11 and the fixed cover 5, and the movement of the card block 20 in the U-shaped seat 16, the card block 20 can be connected or disconnected from the card slot 14, realizing the quick assembly and disassembly of the LED lamp holder 9 and the fixed cover 5, which is convenient for later maintenance and replacement.

[0028] Preferably, the heat dissipation structure includes a cooling fan 6 connected to the inner cavity of the fixed cover 5 via a bracket. The LED lamp holder 9 is provided with multiple sets of heat dissipation fins 10 on the side near the cooling fan 6, and both sides of the fixed cover 5 are equipped with heat exhaust pipes 7 that connect to the heat dissipation port 8. The cooling fan 6 is an exhaust fan, and the operation of the cooling fan 6 can generate suction. In conjunction with the heat dissipation fins 10, the heat generated by the LED lamp holder 9 during operation can be discharged through the heat exhaust pipes 7 and the heat dissipation port 8, thereby achieving rapid heat dissipation of the smart street light and extending the service life of the sensor-type smart street light.

[0029] Preferably, a movable rod 17 is slidably connected inside the U-shaped base 16. The end of the movable rod 17 near the LED lamp holder 9 is connected to the locking block 20. A sliding plate 19 is installed on the outer wall of the movable rod 17. A compression spring 18 is also sleeved on the outer wall of the movable rod 17. The compression spring 18 is located between the outer side of the sliding plate 19 and the inner wall of the U-shaped base 16.

[0030] The U-shaped base 16 is fixedly connected to the outer wall of the fixed cover 5. The moving rod 17 is fixedly connected to the sliding plate 19 and the locking block 20. When the LED lamp holder 9 is installed with the fixed cover 5, the moving rod 17 inside the U-shaped base 16 is pulled outward, causing the sliding plate 19 to move outward. At this time, the compression spring 18 is in a compressed state. The locking block 20 is stored in the U-shaped base 16 through the through hole 15. When the LED lamp holder 9 is installed in the fixed cover 5, after the locking slot 14 is aligned with the through hole 15, the moving rod 17 is released, and the compressed spring 18 automatically returns to its original position. The sliding plate 19 and the locking block 20 move towards the side of the LED lamp holder 9, so that the locking block 20 passes through the through hole 15 and connects with the locking slot 14, thus fixing the position of the LED lamp holder 9 and completing the installation of the LED lamp holder 9. When disassembling, the moving rod 17 is pulled outward, causing the locking block 20 to disengage from the locking slot 14. At this time, the LED lamp holder 9 is no longer restricted and can be removed from the fixed cover 5.

[0031] Preferably, both outer walls of the transparent base plate 11 are provided with magnets 12, and both inner walls of the fixing cover 5 are provided with iron plates 13 that are magnetically connected to the magnets 12; the magnets 12 and the transparent base plate 11 are fixedly connected, and the attraction between the magnets 12 and the iron plates 13 enables the rapid assembly and disassembly of the transparent base plate 11 and the fixing cover 5, which facilitates the assembly and disassembly of the LED lamp holder 9 inside the fixing cover 5.

[0032] Example 2:

[0033] Reference Figure 2 The difference between this embodiment and the first embodiment is that the inner walls of both sets of heat dissipation vents 8 are provided with dustproof nets, and the dustproof nets are connected to the heat dissipation vents 8 by snap-fit. The dustproof nets play a dustproof role, preventing dust from entering the lamp housing and ensuring the cleanliness of the lamp housing 3. The snap-fit ​​dustproof nets are easy to disassemble, replace, and clean.

[0034] It should be noted that the electrical component of this utility model is used to organize the wire harness during operation, and will not cause the wire harness to become tangled.

[0035] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
