Description

Technical Field

[0001] This invention relates to the field of stadium lighting technology, specifically to an outdoor stadium lighting fixture that can be flexibly combined. Background Technology

[0002] Outdoor sports field lighting fixtures are installed on outdoor sports fields to provide athletes and spectators with clear, uniform, and safe light. Most outdoor sports field lighting fixtures consist of two independent lights per pole: one is a long-range projector, illuminating the farthest area from the pole and the center of the field; the other is a short-range projector, illuminating the area directly below the pole to the center of the field, filling in the "dark zone" left by the long-range projector. Before the pole is erected, the pitch and horizontal angles of both lights are initially set on the ground using a protractor, referring to the design drawings. After the pole is erected, fine-tuning begins at night with full illumination: first, the long-range projector is adjusted. Standing at the far end of the field, the operator fine-tunes the pitch and horizontal angles of the long-range projector to ensure its beam falls steadily on the designated target area. After locking the long-range projector, the short-range projector is adjusted. At this point, the focus is on observing the boundary between the two beams, fine-tuning the pitch angle of the short-range projector to ensure a smooth and uniform transition of brightness at the boundary, eliminating obvious bright-dark lines.

[0003] Currently, outdoor stadium lighting fixtures typically use LED light sources. To prevent water and dust damage, the sealing of stadium lighting fixtures is set very high. However, LED light sources are sensitive to heat, and the accumulation of internal heat accelerates the aging of electronic components and chips. This leads to light decay and a decrease in brightness after long-term use. Furthermore, the rate of light decay may vary for different fixtures from the same batch. Some lights dim faster, resulting in a clear dividing line between bright and dark areas at the junction of different lighting fixtures.

[0004] A search revealed that CN224188536U discloses an easily adjustable stadium lighting fixture, comprising a fixed post 1 and a mounting frame 3. A fixed plate 2 is fixedly connected to the top of the fixed post 1, and a controller 201 is mounted on the outside of the fixed plate 2. Multiple lighting fixtures 301 are fixedly connected inside the mounting frame 3, and a limiting shaft 302 is fixedly connected to the top of the mounting frame 3. A gasket 303 is provided on the outside of the limiting shaft 302. The fixture also includes: a pitch adjustment component 4, which is disposed outside the fixed plate 2 and allows adjustment of the pitch angle of the mounting frame 3; and a connecting component 5, which is disposed on the fixed plate 2. At the bottom of the fixed plate 2, the mounting frame 3 is connected and supported by the connecting component 5; the horizontal adjustment component 6 is set outside the connecting component 5 and is used to adjust the horizontal angle of the mounting frame 3; the support component 7 is set outside the fixed column 1 and is used to support the bottom of the connecting component 5; the fixed column 1 is vertically fixed to the court surface, and the fixed plate 2 at its top provides the installation base for subsequent components. Multiple sets of lighting lamps 301 are fixed inside the mounting frame 3 for emitting lighting light. The support component 7 is installed outside the fixed column 1 in conjunction with the support block 701.

[0005] A search revealed that CN224065420U discloses a flexibly combinable outdoor LED stadium lighting fixture, including an LED lamp body and an adjustable slide rail. The adjustable slide rail is connected to the top of the LED lamp body, and a connecting arm is movably connected to the top of the LED lamp body. A telescopic support rod is installed on the top of the connecting arm, and an output rod is provided at the bottom of the telescopic support rod. One end of the telescopic support rod is threadedly connected to a locking knob that matches the output rod. This utility model achieves flexible adjustment and combination of LED lamp bodies by setting up an adjustable slide rail and a connecting arm. The adjustable slide rail is connected to the top of the LED lamp body, and the connecting arm is movably connected to the LED lamp body through a damping shaft, allowing each LED lamp body to slide and be positioned freely on the adjustable slide rail. This not only facilitates the installation and adjustment of the lighting fixture but also allows for flexible combination of the number and position of the fixtures according to actual lighting needs, greatly improving the adaptability and flexibility of the lighting system.

[0006] While the aforementioned patents solved the angle adjustment problem during installation and achieved a uniform lighting effect, during operation, uneven light decay of the lighting fixtures resulted in bright-dark boundaries, requiring manual inspection to identify and adjust the unevenness, which affected user experience. Therefore, we propose a flexible, combinable outdoor stadium lighting fixture. Summary of the Invention

[0007] The purpose of this invention is to provide a flexible combination of outdoor stadium lighting fixtures to solve the problem mentioned in the background art, where the unevenness of the lighting fixtures caused by inconsistent light decay during operation requires manual inspection and adjustment, which affects the user experience.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an outdoor stadium lighting fixture that can be flexibly combined, including a lamp post body; and also including a near-projection lamp and a far-projection lamp, with a fixing frame fixedly connected to the outside of the near-projection lamp and the far-projection lamp respectively; The adjustment component is located between the fixed frame and the main body of the lamp post. The adjustment component adjusts the vertical illumination angle between the near-projection lamp and the far-projection lamp. The monitoring component is located in the middle of the main body of the light pole. When the near-projection light and the far-projection light illuminate the field area, the monitoring component will detect the light intensity of the near-projection light area, the far-projection light area and the area where the two meet. When the monitoring component detects a decrease in illuminance in the near-projection lamp's illuminance area, the adjustment component controls the near-projection lamp to rotate towards the far-projection lamp until the light intensity at the boundary between the near-projection lamp's illuminance area and the far-projection lamp's illuminance area is restored; when the monitoring component detects a decrease in illuminance in the far-projection lamp's illuminance area, the adjustment component controls the far-projection lamp to rotate towards the near-projection lamp.

[0009] The main body of the lamp post has a placement slot in the middle. The monitoring component includes a support plate that is slidably connected to the inner wall of the placement slot. An electric telescopic rod is fixedly connected to the inner wall of the placement slot. A magnet is fixedly connected to the output end of the electric telescopic rod. A magnet is fixedly connected to the side of the support plate near the magnet. The magnetic poles of the opposite sides of the magnets are opposite. When the electric telescopic rod is in the retracted state, the magnets are separated. A relay group is fixedly connected to the outside of the electric telescopic rod. The relay group is electrically connected to the electric telescopic rod and is connected in parallel to the power supply terminal of the long-range lamp. Three detection elements are provided at the end of the support plate away from the electric telescopic rod. The three detection elements are vertically and equidistantly distributed on the surface of the support plate. The three detection elements detect the light intensity of the near-field lamp illumination area, the long-range lamp illumination area, and the area at the boundary between the two, respectively.

[0010] The detection component includes a fixed seat fixedly connected to the surface of the support plate, a rotating seat inside the fixed seat, a limiting component for adjusting the angle of the rotating seat between the rotating seat and the fixed seat, a lens barrel fixedly connected to the end of the rotating seat away from the fixed seat, a condensing lens fixedly connected to the end of the lens barrel away from the rotating seat, a photoelectric sensor fixedly connected to the end of the lens barrel away from the condensing lens, and an adjusting resistor fixedly connected to the inner wall of the rotating seat. The adjusting resistor is connected in series in the circuit where the photoelectric sensor is located, and the adjusting resistor adjusts the voltage signal output by the photoelectric sensor. A voltage comparator is installed on the surface of the lamp post. The voltage comparator receives photoelectric voltage signals transmitted by three photoelectric sensors. The three adjustable resistors have different resistance values. By adjusting the resistors, the initial voltage signals transmitted by the three photoelectric sensors are made the same. The voltage comparator outputs a switching level after comparing it with a preset threshold voltage. The level signal is used to adjust the vertical illumination angle between the near-field lamp and the far-field lamp through the adjustment component.

[0011] The limiting component includes a rotating shaft that is rotatably connected to the inner wall of the fixed seat. The outer side of the rotating shaft is fixedly connected to the rotating seat. One end of the rotating shaft is provided with a locking thread. The inner wall of the fixed seat is provided with an inner and outer threaded sleeve. The inner and outer threaded sleeve is located outside the locking thread of the rotating shaft. The outer side of the inner and outer threaded sleeve is threadedly connected to the inner wall of the fixed seat. The end of the inner and outer threaded sleeve away from the rotating shaft passes through the inner wall of the fixed seat and is fixedly connected to a knob.

[0012] The adjustment assembly includes two mounting seats that are fixedly connected to the main body of the lamp post. The two mounting seats are located on the outside of two fixed frames respectively. An adjustment shaft is fixedly connected to the inner wall of the fixed frame. The adjustment shaft is rotatably connected to the inner wall of the mounting seat. An adjustment component that drives the adjustment shaft to rotate is provided on the inner wall of the fixed frame. When the output voltage of the photoelectric sensor that detects the light intensity of the near-projection lamp's illumination area is lower than a preset threshold, the voltage comparator controls the adjustment component located outside the near-projection lamp to work. The adjustment component controls the near-projection lamp to move closer to the far-projection lamp in the vertical direction. When the output voltage of the photoelectric sensor that detects the light intensity at the boundary between the near-projection lamp's illumination area and the far-projection lamp's illumination area recovers, the voltage comparator controls the adjustment component to stop working. When the output voltage of the photoelectric sensor that detects the light intensity of the long-range projector's illumination area is lower than a preset threshold, the voltage comparator controls the adjustment component located outside the long-range projector to work. The adjustment component controls the long-range projector to move its vertical illumination angle closer to the short-range projector. When the output voltage of the photoelectric sensor that detects the light intensity at the boundary between the short-range projector's illumination area and the long-range projector's illumination area recovers, the voltage comparator controls the adjustment component to stop working.

[0013] The adjusting component includes an adjusting gear fixedly connected to the adjusting shaft, a toothed plate meshing with the outer side of the adjusting gear, the toothed plate slidingly connected to the inner wall of the mounting base, a movable plate fixedly connected to the end of the toothed plate, the movable plate slidingly connected to the inner wall of the mounting base, an electric telescopic rod fixedly connected to the outer side of the movable plate, a micro switch installed on the inner wall of the mounting base, the micro switch being located in the middle and rear region of the movable plate's movement path, and a wireless transmission module fixedly connected to the surface of the lamp post body. When the micro switch is triggered, it transmits a signal to the wireless transmission module.

[0014] Among them, the two electric telescopic poles move in opposite directions. When the electric telescopic pole located outside the near-projection lamp extends, the near-projection lamp rotates upward, and when the electric telescopic pole located outside the far-projection lamp extends, the far-projection lamp rotates downward.

[0015] The lamp post body has a sealing assembly on its inner wall that seals the mirror tube. The sealing assembly includes a sealing arc plate that is rotatably connected to the inner wall of the lamp post body. A rotating plate is fixedly connected to the bottom of the sealing arc plate. The rotating plate is rotatably connected to the inner wall of the lamp post body. In the initial state, the sealing arc plate closes the placement groove. A rotating component is provided on the outer side of the magnet piece 1 that drives the rotating plate to rotate when the magnet piece 1 moves. When the electric telescopic rod 1 pushes the magnet piece 1 to move, the rotating component drives the rotating plate to rotate, and the rotating plate drives the sealing arc plate to release the seal on the placement groove.

[0016] The rotating component includes a toothed plate 2 fixedly connected to a magnet piece 1, a rotating rod rotatably connected to the inner wall of the placement groove, a transmission gear 1 fixedly connected to one end of the rotating rod near the toothed plate 2, the transmission gear 1 meshing with the toothed plate 2, a transmission gear 2 fixedly connected to one end of the rotating rod away from the transmission gear 1, a transmission gear 3 meshing with the outer side of the transmission gear 2, one end of the transmission gear 3 rotatably connected to the inner wall of the lamp post body, and the other end of the transmission gear 3 fixedly connected to the axis of the rotating plate.

[0017] Among them, the sealing arc plate is fixedly connected to the bristles on the side near the condenser lens.

[0018] The present invention has at least the following beneficial effects: When in use, this application uses a monitoring component to detect the light intensity of the near-projection light area, the far-projection light area, and the area where the two meet in the stadium when the far-projection light is powered on. Using three photoelectric sensors and a voltage comparator, it can automatically detect the boundary line caused by light decay when unattended. By adjusting the components, it can fine-tune the angle of the near-projection light and the far-projection light to temporarily fill the dark area, ensuring that the game or training can continue that night and avoiding the impact of sudden light decay on the user.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 Please see Figures 1 to 8 This invention provides a technical solution: a flexibly combinable outdoor sports field lighting fixture, including a lamp post body 1; it also includes a near-projection lamp 2 and a far-projection lamp 3, with a fixing frame 4 fixedly connected to the outside of the near-projection lamp 2 and the far-projection lamp 3 respectively; an adjustment component 5, located between the fixing frame 4 and the lamp post body 1, which adjusts the vertical illumination angle between the near-projection lamp 2 and the far-projection lamp 3; and a monitoring component 6, located in the middle of the lamp post body 1, which detects the light intensity of the area illuminated by the near-projection lamp 2, the area illuminated by the far-projection lamp 3, and the area at the boundary between them when the near-projection lamp 2 and the far-projection lamp 3 illuminate the sports field area. When the monitoring component 6 detects a decrease in illuminance in the area illuminated by the near-projection lamp 2, the adjustment component 5 controls the near-projection lamp 2 to rotate toward the far-projection lamp 3 until the light intensity at the boundary between the areas illuminated by the near-projection lamp 2 and the far-projection lamp 3 is restored; when the monitoring component 6 detects a decrease in illuminance in the area illuminated by the far-projection lamp 3, the adjustment component 5 controls the far-projection lamp 3 to rotate toward the near-projection lamp 2.

[0023] The installation process of this application is consistent with the conventional installation method of stadium lighting fixtures. The near-projection light 2 is responsible for the area from the bottom of the light pole to the middle of the field, and the far-projection light 3 is responsible for the area from the middle of the field to the farthest point. After the staff adjusts the illumination angle of the near-projection light 2 and the far-projection light 3, the brightness transition at the junction is smooth and uniform, eliminating obvious bright and dark dividing lines.

[0024] At night, when the stadium lights are turned on, the long-range projector 3 and the short-range projector 2 are powered on. At this time, the monitoring component 6 automatically unfolds to detect the light intensity in the areas illuminated by the short-range projector 2, the areas illuminated by the long-range projector 3, and the areas where the two meet. In this way, without human intervention, the system can automatically detect the boundary line caused by light decay and temporarily fill in the dark area by adjusting the angle of the short-range projector 2 and the long-range projector 3 through the adjustment component 5, so as to avoid affecting the user experience due to sudden light decay.

[0025] A placement slot 7 is provided in the middle of the main body 1 of the lamp post. The monitoring component 6 is normally stored in the placement slot 7 and extends out when in operation. The monitoring component 6 includes a support plate 60 that is slidably connected to the inner wall of the placement slot 7. An electric telescopic rod 61 is fixedly connected to the inner wall of the placement slot 7. The electric telescopic rod 61 is powered by an independent power supply. A magnet 62 is fixedly connected to the output end of the electric telescopic rod 61. A magnet 63 is fixedly connected to the side of the support plate 60 near the magnet 62. The magnetic poles of the opposite sides of the magnet 62 and the magnet 63 are opposite. The electric telescopic rod 61 is in a position where... In the retracted state, magnet 62 and magnet 63 are separated. A relay group 64 is fixedly connected to the outside of the electric telescopic rod 61. The relay group 64 is electrically connected to the electric telescopic rod 61. The coil of the relay group 64 is connected in parallel to the power supply terminal of the long-range lamp 3. Three detection elements 65 are provided on the end of the support plate 60 away from the electric telescopic rod 61. The three detection elements 65 are vertically and equidistantly distributed on the surface of the support plate 60. The three detection elements 65 respectively detect the light intensity of the near-field lamp 2 illumination area, the long-range lamp 3 illumination area, and the area at the junction of the two.

[0026] The relay group 64 consists of two relays. The coil of the first relay is connected in parallel to the power supply terminal of the floodlight 3, and the normally open contact of the first relay is connected in series in the forward power supply circuit of the electric telescopic pole 61. The coil of the second relay is also connected in parallel to the power supply terminal of the floodlight 3, and the normally closed contact of the second relay is connected in series in the reverse power supply circuit of the electric telescopic pole 61.

[0027] When the lights are turned on at night, the projector lamp 3 lights up, the relay group 64 is energized, the normally open contact of the first relay closes, the normally closed contact of the second relay opens, the forward power supply circuit of the electric telescopic rod 61 is connected, the electric telescopic rod 61 extends forward and pushes out the support plate 60. When the lights are turned off during the day, the power supply to the projector lamp 3 is cut off, and the relay group 64 is released. The normally open contact of the first relay is opened, and the normally closed contact of the second relay is closed, connecting the reverse power supply circuit of the electric telescopic rod 61. The electric telescopic rod 61 reverses and retracts, driving the support plate 60 to retract into the placement slot 7.

[0028] When the electric telescopic rod 61 extends, it pushes the magnet 62 to move. Since the magnetic poles of the opposite sides of the magnet 62 and the magnet 63 are opposite, the magnet 62 and the magnet 63 attract each other and move together after they come into contact. The magnet 63 drives the support plate 60 to move. The support plate 60 pushes multiple detection elements 65 out of the placement slot 7. The light intensity of the near-field lamp 2 illumination area, the far-field lamp 3 illumination area, and the area at the junction of the two is detected by the detection elements 65.

[0029] When the electric telescopic rod 61 retracts, the magnet 62 and the magnet 63 attract each other. The magnet 62 pulls the magnet 63 to move, and the magnet 63 pulls the support plate 60 back. After the support plate 60 is reset, the electric telescopic rod 61 continues to retract, while the magnet 63 has reached the final position with the support plate 60. At this time, the electric telescopic rod 61 pulls the magnet 62 and the magnet 63 to separate.

[0030] The detection component 65 includes a fixed base 66 fixedly connected to the surface of the support plate 60. A rotating base 67 is provided inside the fixed base 66. A limiting component 68 for adjusting the angle of the rotating base 67 is provided between the rotating base 67 and the fixed base 66. A lens barrel 69 is fixedly connected to the end of the rotating base 67 away from the fixed base 66. A condensing lens 610 is fixedly connected to the end of the lens barrel 69 away from the rotating base 67. A photoelectric sensor 611 is fixedly connected to the end of the lens barrel 69 away from the condensing lens 610. An adjusting resistor 612 is fixedly connected to the inner wall of the rotating base 67. The adjusting resistor 612 is connected in series in the circuit where the photoelectric sensor 611 is located. The adjusting resistor 612 adjusts the voltage signal output by the photoelectric sensor 611.

[0031] The optical axes of the three photoelectric sensors 611 point to the near-projection light area, the far-projection light area, and the area where the two meet, respectively. The specific angles can be adjusted according to the size of the court.

[0032] The adjusting resistor 612 is a precision adjustable resistor with a resistance range of 1kΩ-10kΩ. For example, when the output voltage of the photoelectric sensor 611 is 2.0-2.5V under standard illumination, a 3kΩ adjusting resistor in series can be used to divide and calibrate the output voltage to 3.0V. The specific resistance value is adjusted according to the photoelectric sensor model and threshold voltage matching.

[0033] A voltage comparator 613 is installed on the surface of the lamp post body 1. The voltage comparator 613 receives photoelectric voltage signals transmitted by three photoelectric sensors 611. The resistance values ​​of the three adjusting resistors 612 are different. By adjusting the resistors 612, the initial voltage signals transmitted by the three photoelectric sensors 611 are made the same. After comparing the voltage with the preset threshold voltage, the voltage comparator 613 outputs a switching level. The level signal adjusts the vertical illumination angle between the near-projection lamp 2 and the far-projection lamp 3 through the adjusting component 5.

[0034] The voltage comparator 613 uses an LM339 quad differential comparator in a 14-pin package. It integrates four independent voltage comparison channels. Three of these channels correspond to the photoelectric sensor 611 for detecting the illuminance of the near-field lamp 2, the photoelectric sensor 611 for detecting the illuminance of the boundary area, and the photoelectric sensor 611 for detecting the illuminance of the far-field lamp 3. The remaining channel is reserved for backup.

[0035] At the factory, by adjusting the three regulating resistors 612, the initial voltage signals output by the three photoelectric sensors 611 are made consistent under healthy lighting conditions (all are calibrated to 3.0V in this application).

[0036] The light decay trigger threshold for the near-light lamp 2 is set to 2.5V (corresponding to an illuminance reduction to approximately 83%). 2.5V is connected to the non-inverting input of the first comparator in voltage comparator 613, and the output voltage Va of the photoelectric sensor 611 corresponding to the near-light lamp 2 is connected to the inverting input. When Va < 2.5V, voltage comparator 613 outputs a high level, indicating that light decay of the near-light lamp 2 has been detected.

[0037] The light decay trigger threshold for the long-range lamp 3 is also set to 2.5V. The 2.5V is connected to the non-inverting input of the second comparator, and the output voltage Vc of the photoelectric sensor 611 corresponding to the long-range lamp 3 is connected to the inverting input. When Vc < 2.5V, the voltage comparator 613 outputs a high level, indicating that the light decay of the long-range lamp 3 has been detected.

[0038] Boundary zone stop threshold: set to 2.7V (representing that the boundary line has been re-lit to an acceptable level). Connect 2.7V to the inverting input of the third comparator, and connect the output voltage Vb of the photoelectric sensor 611 corresponding to the boundary zone to the non-inverting input. When Vb ≥ 2.7V, the voltage comparator 613 outputs a high level to issue a stop command.

[0039] The specific implementation of the logic circuit is a set of AND / OR gates or a microcontroller truth table: When the first path is high (Va<2.5V) and the second path is low (Vc≥2.5V) → it is determined as "light decay of near-projection lamp 2". When the second path is high and the first path is low → "light decay of far-projection lamp 3". When both paths are high at the same time → "light decay of both lamps at the same time" → compensation for near-projection lamp 2 is given priority.

[0040] The limiting component 68 includes a rotating shaft 614 rotatably connected to the inner wall of the fixed seat 66. The outer side of the rotating shaft 614 is fixedly connected to the rotating seat 67. One end of the rotating shaft 614 is provided with a locking thread 615. The inner wall of the fixed seat 66 is provided with an internal and external threaded sleeve 616. The internal and external threaded sleeve 616 is located outside the locking thread 615 of the rotating shaft 614. The outer side of the internal and external threaded sleeve 616 is threadedly connected to the inner wall of the fixed seat 66. The end of the internal and external threaded sleeve 616 away from the rotating shaft 614 passes through the inner wall of the fixed seat 66 and is fixedly connected to a knob 617.

[0041] When the knob 617 is turned, the internal and external threaded sleeve 616 is screwed in in the forward direction. Its internal thread engages with the locking thread 615 of the rotating shaft 614 and presses against the end face of the fixed seat 66, locking the angle of the rotating seat 67. When it is screwed out in the reverse direction, the internal and external threaded sleeve 616 separates from the rotating shaft 614, and the rotating shaft 614 can be rotated freely to adjust the angle.

[0042] The adjustment assembly 5 includes two mounting seats 50 fixedly connected to the lamp post body 1. The two mounting seats 50 are located on the outside of the two fixing frames 4 respectively. An adjustment shaft 51 is fixedly connected to the inner wall of the fixing frame 4. The adjustment shaft 51 is rotatably connected to the inner wall of the mounting seat 50. An adjustment component 52 that drives the adjustment shaft 51 to rotate is provided on the inner wall of the fixing frame 4.

[0043] When the output voltage of the photoelectric sensor 611, which detects the light intensity of the illumination area of ​​the near-projection lamp 2, is lower than a preset threshold, the voltage comparator 613 controls the adjustment component 52 located outside the near-projection lamp 2 to work. The adjustment component 52 controls the illumination angle of the near-projection lamp 2 to move closer to the far-projection lamp 3 in the vertical direction. When the output voltage of the photoelectric sensor 611, which detects the light intensity at the junction of the illumination areas of the near-projection lamp 2 and the far-projection lamp 3, returns to the preset threshold, the voltage comparator 613 controls the adjustment component 52 to stop working.

[0044] When the output voltage of the photoelectric sensor 611, which detects the light intensity of the illumination area of ​​the long-range lamp 3, is lower than a preset threshold, the voltage comparator 613 controls the adjustment component 52 located outside the long-range lamp 3 to work. The adjustment component 52 controls the vertical illumination angle of the long-range lamp 3 to move closer to the near-range lamp 2. When the output voltage of the photoelectric sensor 611, which detects the light intensity at the junction of the illumination area of ​​the near-range lamp 2 and the illumination area of ​​the long-range lamp 3, returns to the preset threshold, the voltage comparator 613 controls the adjustment component 52 to stop working.

[0045] The adjusting component 52 includes an adjusting gear 53 fixedly connected to the adjusting shaft 51. A toothed plate 54 meshes with the outer side of the adjusting gear 53. The toothed plate 54 is slidably connected to the inner wall of the mounting base 50. A movable plate 55 is fixedly connected to the end of the toothed plate 54. The movable plate 55 is slidably connected to the inner wall of the mounting base 50. An electric telescopic rod 56 is fixedly connected to the outer side of the movable plate 55. A micro switch 57 is installed on the inner wall of the mounting base 50. The micro switch 57 is located in the middle and rear part of the moving path of the movable plate 55. A wireless transmission module 58 is fixedly connected to the surface of the lamp post body 1. After the micro switch 57 is triggered, it transmits a signal to the wireless transmission module 58. The wireless transmission module 58 uploads the trigger signal to the background to realize remote status reporting and notify maintenance personnel to replace the long-range lamp 3 and the short-range lamp 2 during the day.

[0046] The wireless transmission module 58 adopts a LoRa wireless communication module with a working frequency of 470-510MHz and a transmission power of ≤17dBm. When the micro switch 57 is triggered, the module sends an alarm data packet containing the light pole number and the fault type to the background server.

[0047] The first output of voltage comparator 613 is connected to the forward power supply terminal of the electric telescopic pole 2 56 corresponding to the near-field lamp 2 through the drive circuit, and the second output is connected to the forward power supply terminal of the electric telescopic pole 2 56 corresponding to the far-field lamp 3 through the drive circuit. When the first output is high, the drive circuit of voltage comparator 613 turns on the electric telescopic pole 2 56 circuit on the side of the near-field lamp 2, causing it to extend.

[0048] The two electric telescopic poles 256 move in opposite directions. When the electric telescopic pole 256 located outside the near-projection lamp 2 extends, the near-projection lamp 2 rotates upward. When the electric telescopic pole 256 located outside the far-projection lamp 3 extends, the far-projection lamp 3 rotates downward.

[0049] When the electric telescopic rod 56 on the outside of the near-projection lamp 2 extends, the toothed plate 54 moves in a direction that causes the near-projection lamp 2 to rotate upward (increase the elevation angle), and its light spot moves toward the far-projection lamp 3.

[0050] When the electric telescopic rod 56 on the outside of the long-range lamp 3 extends, the toothed plate 54 moves in a direction that causes the long-range lamp 3 to rotate downward (the elevation angle decreases), and its light spot moves toward the direction of the near-range lamp 2.

[0051] The inner wall of the lamp post body 1 is provided with a sealing assembly 8 that seals the lens barrel 69. The sealing assembly 8 includes a sealing arc plate 80 that is rotatably connected to the inner wall of the lamp post body 1. The sealing arc plate 80 normally closes the placement groove 7 to protect the internal optical elements. A rotating plate 81 is fixedly connected to the bottom of the sealing arc plate 80. The rotating plate 81 is rotatably connected to the inner wall of the lamp post body 1. The sealing arc plate 80 closes the placement groove 7 in the initial state. A rotating component 82 is provided on the outer side of the magnet piece 62, which drives the rotating plate 81 to rotate when the magnet piece 62 moves. When the electric telescopic rod 61 pushes the magnet piece 62 to move, the rotating component 82 drives the rotating plate 81 to rotate, and the rotating plate 81 drives the sealing arc plate 80 to release the seal on the placement groove 7.

[0052] The sealing arc plate 80 closes the placement groove 7 when the lights are off during the day; when the lights are on at night, the sealing arc plate 80 rotates and opens before the support plate 60 extends, making way for the detection channel; after the lights are turned off during the day, the sealing arc plate 80 automatically closes after the support plate 60 retracts.

[0053] The rotating component 82 includes a toothed plate 83 fixedly connected to the magnet piece 62. A rotating rod 84 is rotatably connected to the inner wall of the placement groove 7. A transmission gear 85 is fixedly connected to one end of the rotating rod 84 near the toothed plate 83. The transmission gear 85 meshes with the toothed plate 83. A transmission gear 86 is fixedly connected to the other end of the rotating rod 84 away from the transmission gear 85. A transmission gear 87 meshes with the outer side of the transmission gear 86. One end of the transmission gear 87 is rotatably connected to the inner wall of the lamp post body 1, and the other end of the transmission gear 87 is fixedly connected to the axis of the rotating plate 81.

[0054] When the electric telescopic rod 61 extends and pushes out the support plate 60, the magnet 62 drives the toothed plate 83 to move, the toothed plate 83 drives the transmission gear 85 to rotate, the transmission gear 85 drives the rotating rod 84 to rotate, the rotating rod 84 drives the transmission gear 86 to rotate, the transmission gear 86 drives the transmission gear 87 to rotate, and the transmission gear 87 causes the rotating plate 81 to drive the sealing arc plate 80 to rotate, thus opening up the detection channel.

[0055] When used at night, the relay group 64 connected in parallel to the power supply terminal of the long-range lamp 3 is energized and engaged, the electric telescopic rod 61 is energized and extends, the electric telescopic rod 61 pushes the support plate 60 to move outward, and at the same time, through the toothed plate 83, the transmission gear 85, the transmission gear 87 and the rotating plate 81, the sealing arc plate 80 is opened, making way for the detection channel.

[0056] After the support plate 60 moves into place, magnet 62 and magnet 63 are attracted to each other, and the three photoelectric sensors 611 begin to continuously detect the light intensity of their respective target areas and output voltage signals to the voltage comparator 613 (all are 3.0V when healthy).

[0057] When the light intensity of the near-projection lamp 2 decreases, the near-end illuminance drops, and the near-end sensor Va falls below 2.5V, while the far-end sensor Vc remains above 2.5V. The first comparator of voltage comparator 613 outputs a high level, and the logic circuit determines that "the light intensity of the near-projection lamp 2 has decreased." The control circuit of voltage comparator 613 drives the corresponding electric telescopic rod 56 of the near-projection lamp 2 to rotate forward and extend. Through the moving plate 55, the toothed plate 54 is pushed, so that the elevation angle of the near-projection lamp 2 gradually increases and the light spot moves outward. As the light spot of the near-projection lamp 2 sweeps across the boundary area, the boundary area sensor Vb begins to rise. When Vb rises to 2.7V, the third comparator of voltage comparator 613 outputs a high level. This signal immediately cuts off the power supply to the electric telescopic rod 56 outside the near-projection lamp 2 through the logic circuit of voltage comparator 613. The electric telescopic rod 56 stops by self-locking. At this time, the boundary line of the boundary area is filled, but a new slight dark area appears below the lamp post. The system remains locked and continues to monitor.

[0058] When the light of the long-range lamp 3 decays, the illuminance at the far end decreases, Vc < 2.5V, Va is normal, the second comparator of voltage comparator 613 outputs a high level, and the logic circuit judges it as "light decay of long-range lamp 3". The electric telescopic rod 56 corresponding to long-range lamp 3 extends, and pushes the toothed plate 54 through the moving plate 55, so that the elevation angle of long-range lamp 3 decreases and the light spot moves to the near end. The boundary area Vb rises. When Vb rises to 2.7V, the third comparator of voltage comparator 613 outputs a high level. This signal immediately cuts off the power supply to the electric telescopic rod 56 outside long-range lamp 3 through the logic circuit of voltage comparator 613. The electric telescopic rod 56 stops by self-locking. At this time, the farthest end of the site becomes slightly darker and the boundary area returns to smooth.

[0059] When the moving plate 55 moves past the micro switch 57, it indicates that the corresponding lamp has suffered severe light decay. The moving plate 55 presses down the micro switch 57. At this time, the system completes the last compensation while sending an immediate replacement signal to the backend through the wireless transmission module 58.

[0060] After the lights are turned off during the day, the power to the long-range projector 3 is cut off, the relay group 64 is released, the electric telescopic pole 61 retracts, driving the support plate 60 to retract, and the sealing arc plate 80 closes. Staff then replace the lights in pairs according to the alarm information.

[0061] Example 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the sealing arc plate 80 is fixedly connected to the side of the condenser lens 610, so that the sealing arc plate 80 will wipe the surface of the condenser lens 610 during the opening and closing process, thus achieving self-cleaning.
