Abstract
Description
Technical Field
[0001] This invention belongs to the field of lampshade technology, specifically an energy-saving park landscape lampshade and landscape light. Background Technology
[0002] Currently, beautifying the environment, creating a pleasant atmosphere, improving the happiness index, and making our cities more tasteful are common pursuits for many people. Landscape lighting and artistic patterns have become essential decorations. As the outermost visual focal point and optical control component of a lamp, the performance and design of the lampshade directly determine the final light and shadow effect, visual comfort, and long-term durability of the lamp. The lampshade emits light of various colors through its unique structure, sometimes bright and sometimes dim, giving people an aesthetic enjoyment. The artistic patterns are lifelike, giving people endless imagination.
[0003] Publication number CN108506892B relates to a lamp cover and a lamp, wherein the lamp cover is at least partially light-transmitting and designed to connect with a grooved housing portion to form a closed lamp housing, the lamp cover being basin-shaped and having a surrounding, outwardly pointing splash-proof edge in a region provided for connection with the grooved housing portion, the splash-proof edge being disconnected in a locking region provided for locking with the grooved housing portion.
[0004] Furthermore, after prolonged use, the existing lampshades may tilt at a certain angle due to environmental factors such as wind, sun, or extreme weather. The light emitted by the tilted landscape lights is more likely to cause glare to pedestrians.
[0005] When the tilt angle of the lampshade increases further, the snap-fit components inside the lampshade will disengage under their own weight, which will not only reduce the sealing of the lampshade, but also affect the subsequent snap-fit and protection effect of the lampshade on the internal components.
[0006] Furthermore, if the lampshade tilts to its maximum angle, the long-term effects of gravity will cause the landscape light to tip over. When pedestrians approach, the landscape light that is at risk of tipping over will not issue a warning to remind pedestrians to stay away, nor will it remind staff to maintain the landscape light. Over time, there is a risk of it tipping over and injuring pedestrians.
[0007] The landscape lights are installed in open outdoor spaces without any protective measures. When thieves steal and remove the lamp covers and internal structures, there is no effective warning or alert. Summary of the Invention
[0008] To address the above problems, this invention provides an energy-saving park landscape light cover and landscape light.
[0009] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving park landscape light cover, comprising a cover body and a lamp housing, and further comprising: The air pressure section, with multiple air pressure sections fixedly installed inside the cover, is used for tipping warning. The air pressure section includes a pressure accumulator chamber, which is opened around the inside of the cover to store pressure. The control unit, with multiple control units movably located inside the enclosure, is used to change the air pressure inside the accumulator chamber and control the direction of the light beam; Sealing parts, multiple sealing parts are fixedly installed at the bottom of the cover to seal the cover; The adjustment section, with multiple adjustment sections movably installed inside the lamp housing, is used to adjust the direction of light illumination. When the cover is tilted, the control section drives the adjustment section to adjust the direction of light. When the tilt angle is too large, the control section will cause the air pressure section to issue a warning signal. When thieves illegally remove the cover, the sealing section will cause the air pressure section to issue a warning signal and prevent the cover from rotating and being removed under air pressure.
[0010] Preferably, the pneumatic section further includes: The air inlet is fixedly connected to the outside of the cover and is connected to the accumulator chamber to fill the accumulator chamber with gas. The warning tube is fixedly connected to the outside of the cover and is connected to the pressure accumulator. It is used to issue a warning when the pressure in the pressure accumulator increases to the preset pressure value. The warning tube is equipped with a pressure sensor, and the threshold of the pressure sensor is the preset pressure value. The connecting hole is located inside the cover and is used to provide space for the movement of the control unit. One side of the connecting hole is connected to the accumulator chamber.
[0011] Preferably, the control unit includes: The chute is located inside the cover; The control block is slidably connected inside the slide groove and is used to move and adjust the rotation direction of the regulating part; The adjusting rod has one end of its outer surface rotatably connected to the control block, and the other end of its outer surface rotatably connected to the inner wall of the cover via a thread, and is used to rotate and adjust the position of the control block inside the slide groove. The handle is fixedly connected to the end of the adjusting rod away from the control block and is used to drive the adjusting rod to rotate.
[0012] Preferably, the manufacturing process also includes: The movable cavity is located inside the cover and is connected to the connecting hole; The counterweight is sealed and slidably connected inside the movable cavity, and is used to sense changes in the angle of the cover and move accordingly; The elastic element has one end fixedly connected to the counterweight on the side away from the control block, and the other end fixedly connected to the inside of the cover.
[0013] Preferably, the control unit further includes: The guide body has one end fixedly connected to the side wall of the control block near the counterweight, and the other end fixedly connected to the side wall of the counterweight near the control block. It is used to move the counterweight by moving the control block, and the guide body is elastic. The rotating wheel, which is movably connected inside the cover via a rotating rod, is used to provide support for the movement of the guide body, and the rotating wheel is located between the control block and the counterweight block; The regulating chamber is located at the bottom of the movable chamber and is U-shaped; the movable chamber is connected to the outside through a pressure relief hole. An adjusting plate is movably connected to the inside of one side of the adjusting cavity. A pressure baffle is provided on its top, and the pressure baffle seals part of the adjusting cavity. The adjusting plate is located below the pressure relief hole and is used to drive the adjusting part to change direction.
[0014] Preferably, the sealing part includes: The card slot is located at the bottom of the cover; The card plate is fixedly connected to the top of the lamp housing and is used to engage with the card slot to snap the cover and the lamp housing together. The sealing plate is movably connected inside the accumulator chamber and is used to seal the gap after the slot and the plate are engaged.
[0015] Preferably, the adjustment section includes: Rotating rods, multiple rotating rods are rotatably connected inside the lamp housing; Louvers, multiple louvers are fixedly connected to the outside of the rotating rod, used to adjust the direction of light illumination; Connectors: The top of multiple connectors is fixedly connected to the bottom of the adjusting plate, and the bottom of the connectors is hinged to one side of the top of the uppermost louver. They are used to cooperate with the adjusting plate to drive the rotating rod to rotate. The hinge rod is movably hinged to one side of multiple louvers and is used to drive the multiple louvers to rotate synchronously.
[0016] A landscape light, which uses an energy-saving park landscape light cover as described above, further includes: The lamp post is fixedly connected to the bottom of the lamp housing and is used to secure it to the ground during installation. The lamp body is fixedly installed inside the cover and is used to emit light.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses the movement of the control block in the control unit to drive the angle change of the louvers in the adjustment unit, so that the light direction of the landscape light can be diffused in the desired direction, and the light body can be colored differently after passing through the lampshade, either bright or dim, giving people an aesthetic enjoyment and making the artistic patterns lifelike.
[0018] 2. This invention utilizes the principle of counterweight sensing gravity. When the cover tilts, the counterweight changes position due to gravity, thereby causing the louvers to change angle via the guide body and adjustment plate. After tilting, the light illumination angle of the louvers on the lower side increases, while the light illumination angle of the louvers on the higher side decreases, thus avoiding glare for pedestrians while ensuring that the illumination range of the landscape lights remains unchanged.
[0019] 3. In this invention, through the cooperation of the clamping plate, sealing plate, etc., when the cover body is further tilted, causing the clamping plate and sealing plate to disengage and affecting the sealing effect, the counterweight block moves further along the movable cavity to increase the reverse pushing force on the sealing plate, thereby ensuring the clamping and fixing effect of the sealing plate on the clamping plate.
[0020] 4. This invention utilizes the coordinated operation of a counterweight and a warning tube. When the tilt angle of the landscape light is too large, the internal pressure of the counterweight's accumulator reaches the preset pressure value. At this time, the warning tube opens and emits a warning sound to remind passersby not to approach to avoid injury and to prompt personnel to carry out maintenance.
[0021] 5. Through the coordinated operation of the sealing part and the warning tube, when thieves dismantle the landscape light cover, the rotation of the cover will cause the sealing plate to push back the pressure storage chamber, increasing the internal air pressure and reaching the preset pressure value. Therefore, the warning tube will open and emit a warning sound to prevent the landscape light from being dismantled and stolen. Attached Figure Description

Detailed Implementation
[0024] 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 users of ordinary skills in the art without creative effort are within the scope of protection of the present invention.
[0025] This invention provides, for example Figures 1 to 8 The energy-saving park landscape light cover shown includes a cover body 1 and a lamp housing 2. The cover body 1 and the lamp housing 2 serve to protect the internal parts and the lamp body 4, preventing them from being directly affected by the external environment. The cover body 1 includes an upper body and a lower body, and the lower body has a groove inside. During installation, the internal components are installed in the corresponding grooves. After installation, the upper body and the lower body are connected and sealed.
[0026] The energy-saving park landscape light cover also includes: an air pressure unit 5. Multiple air pressure units 5 are fixedly installed inside the cover body 1 for tilt warning. When the landscape light tilts to a certain angle, the air pressure unit 5 will issue a warning through its internal components, which not only reminds passersby to stay away, but also reminds staff to maintain the light cover and its internal structure in a timely manner.
[0027] Control unit 6, multiple control units 6 are movably arranged inside the cover 1, used to change the air pressure inside the pressure accumulator 501 and control the direction of light illumination. The control unit 6 drives the adjustment unit 8 to change the rotation angle through the cooperation of internal components, thereby controlling the direction of light illumination, so that the light illuminates in the preset direction and avoids causing glare to passers-by.
[0028] A sealing part 7, multiple sealing parts 7 are fixedly installed at the bottom of the cover 1 to seal the gap between the cover 1 and the lamp housing 2. The sealing part 7 seals the gap between the cover 1 and the lamp housing 2, which can prevent external dust, insects, etc. from entering the lamp housing 2 and causing adverse effects on the landscape light. In addition, the sealing part 7 works in conjunction with the warning tube 503 of the air pressure part 5. When a thief illegally removes the cover 1, the sealing part 7 causes the air pressure inside the pressure storage chamber 501 to change through the internal components, thereby causing the warning tube 503 to issue a warning signal.
[0029] Adjustment unit 8, multiple adjustment units 8 are movably disposed inside the lamp housing 2, used to adjust the direction of light illumination; when the cover 1 and lamp housing 2 are tilted, the control unit 6 drives the adjustment unit 8 to adjust the direction of light. When the tilt angle is too large, the control unit 6 will cause the air pressure unit 5 to issue a warning signal. In addition, during use, the control unit 6 can manually drive the adjustment unit 8 to change the rotation direction so that the light inside the landscape light is emitted in the preset direction.
[0030] The pressure unit 5 also includes: a pressure accumulator 501, which is located around the inside of the housing 1 and is used to store pressure. After installation, the pressure accumulator 501 is pressurized through the air inlet 502 to maintain a high pressure state inside the pressure accumulator 501 that is lower than the preset pressure value; an air inlet 502, which is fixedly connected to the outside of the housing 1 and is used to fill the pressure accumulator 501 with gas, and the air inlet 502 is connected to the pressure accumulator 501; and a warning tube 503, which is fixedly connected to the outside of the housing 1 and is used to issue a warning when the pressure inside the pressure accumulator 501 increases to the preset pressure value. The warning tube 503 is equipped with a pressure sensor, the threshold of which is the preset pressure value, and the warning tube 503 is connected to the pressure accumulator 501. When the pressure inside the pressure accumulator 501 increases and exceeds the preset pressure value, the pressure inside the warning tube 503 causes the pressure sensor to activate the alarm and issue a warning signal.
[0031] The connecting hole 504 is located inside the cover 1 to provide space for the movement of the control unit 6. One side of the connecting hole 504 is connected to the pressure accumulator 501. When the movement of the control unit 6 causes the pressure inside the pressure accumulator 501 to reach the preset pressure value, a warning signal is issued.
[0032] During use, after the landscape light is installed, the pressure accumulator 501 is pressurized through the air inlet 502 so that the internal pressure of the pressure accumulator 501 is less than the preset pressure value. When the landscape light is tilted to a certain angle or is illegally removed, the sealing plate 704 will move and reduce the pressure accumulator space of the pressure accumulator 501, thereby increasing the internal pressure and reaching the preset pressure value. At this time, the pressure sensor inside the warning tube 503 will activate the alarm and issue a warning signal.
[0033] The control unit 6 includes: a slide groove 601, which is formed inside the cover 1, providing space for the sliding of the control block 602; a control block 602, which is slidably connected inside the slide groove 601, used to move and adjust the rotation direction of the adjustment unit 8. The movement of the control block 602 will drive the adjustment unit 8 to change its rotation direction through other components inside the control unit 6, thereby changing the direction of light illumination; and an adjustment rod 603, one end of which is rotatably connected to the control block 602, and the other end of which is rotatably connected to the inner wall of the cover 1 through a thread, used to rotate and adjust the position of the control block 602 inside the slide groove 601. The threaded rotation of the adjustment rod 603 and the cover 1 will drive the adjustment unit 8 to change its rotation direction. The control block 602 can be moved to actively set the direction of the landscape light's illumination. Furthermore, when the landscape light malfunctions and requires repair by removing the cover 1, the control block 602 moves towards the adjusting rod 603. This reduces the internal pressure of the pressure accumulator 501. Then, the cover 1 is rotated. At this point, the sealing plate 704 pressing on the pressure accumulator 501 will not cause the internal pressure to reach the preset value, and no warning will be issued. The handle 604 is fixedly connected to the end of the adjusting rod 603 furthest from the control block 602, and is used to rotate the adjusting rod 603. The handle 604 makes it easier to rotate the adjusting rod 603.
[0034] The movable cavity 605 is located inside the cover 1. The movable cavity 605 provides space for the counterweight 607 to move under gravity, and it is connected to the connecting hole 504. The counterweight 607 is slidably connected inside the movable cavity 605 and is used to sense changes in the angle of the cover 1 and move accordingly. The counterweight 607 is used to sense the movement under gravity caused by changes in the angle of the cover 1. An elastic element 606 is fixedly connected at one end to the side of the counterweight 607 away from the control block 602. The other end is fixedly connected to the inside of the cover 1. The elastic element 606 is used to move the counterweight 607 when the position of the control block 602 changes, and to balance the gravity of part of the counterweight 607 when it tilts due to the landscape light. The movable cavity 605 and the counterweight 607 are relatively smooth, that is, the friction coefficient between the two is made small enough by adding lubricant. Therefore, when the cover 1 tilts at different angles, the counterweight 607 moves in the movable cavity 605 under the gravity and will not cause friction or jamming.
[0035] The guide body 609 has one end fixedly connected to the side wall of the control block 602 near the counterweight 607, and the other end fixedly connected to the side wall of the counterweight 607 near the control block 602. It is used to move the counterweight 607 by moving the control block 602. The guide body 609 is elastic. When the counterweight 607 moves due to the change of angle of the cover 1, the guide body 609 will be stretched when the counterweight 607 moves away from the control block 602. Due to the elasticity of the guide body 609, the control block 602 will not be moved. The rotating wheel 610 is movably connected to the inside of the cover 1 through a rotating rod. It is used to provide support for the movement of the guide body 609. The rotating wheel 610 is located between the control block 602 and the counterweight 607.
[0036] The regulating cavity 612 is located at the bottom of the movable cavity 605 and is U-shaped. The movable cavity 605 is connected to the outside through a pressure relief hole. The regulating plate 611 is movably connected to the inside of one side of the regulating cavity 612. A baffle plate is provided on its top, and the baffle plate seals part of the regulating cavity 612. The regulating plate 611 is located below the pressure relief hole. The regulating plate 611 is used to drive the regulating part 8 to change direction. The regulating plate 611 and the baffle plate form a "7" shaped structure. When the counterweight 607 moves away from the control block 602, the air pressure inside the movable cavity 605 increases, causing air to flow inside the refrigerator regulating cavity 612. The increased air pressure inside the regulating cavity 612 drives the regulating plate 611 to move upward through the baffle plate. When the counterweight 607 moves closer to the control block 602, the air pressure inside the movable cavity 605 decreases. The regulating plate 611 moves downward under its own weight.
[0037] After the landscape lights are installed, the control block 602 can be moved within the slide groove 601 by the adjustment rod 603 driven by the handle 604. The guide body 609 fixedly connected to the control block 602 is stretched. Under the action of the tension, the counterweight 607 is pulled in the movable cavity 605 towards the control block 602, thereby reducing the air pressure inside the movable cavity 605. Under the action of the air pressure and the gravity of the adjustment plate 611, the adjustment plate 611 moves downward and drives the adjustment part 8 to change direction, thereby achieving the effect of controlling the direction of light illumination.
[0038] Furthermore, during the aforementioned process, the movement of the counterweight 607 reduces the internal pressure of the accumulator chamber 501. When disassembly and maintenance are required, rotating the cover 1 causes the sealing plate 704 to partially retract into the accumulator chamber 501. This process does not cause the internal pressure of the accumulator chamber 501 to reach the preset pressure value, and therefore no warning is issued.
[0039] The sealing part 7 includes: a slot 701, which is opened at the bottom of the cover 1; a plate 702, which is fixedly connected to the top of the lamp housing 2, and is used to cooperate with the slot 701 to snap the cover 1 and the lamp housing 2 together; and a sealing plate 704, which is movably connected to the inside of the pressure accumulator 501, and is used to seal the gap after the slot 701 and the plate 702 are snapped together.
[0040] During installation, the cover 1 and lamp housing 2 are secured by inserting the card plate 702 into the card slot 701 and rotating it. Then, the sealing plate 704 is pushed out of the gap in the card slot 701 by the internal pressure of the accumulator chamber 501, sealing and securing the cover 1 and lamp housing 2 to prevent external dust, insects, and other impurities from entering the landscape light and causing damage. When the staff needs to disassemble and repair the cover 1, the pressure inside the accumulator chamber 501 is reduced by the action of the control unit 6. Then, the cover 1 is rotated, and the card plate 702 pushes the sealing plate 704 back into the accumulator chamber 501. This process will not cause the internal pressure of the accumulator chamber 501 to reach the preset pressure value, so no warning signal will be issued.
[0041] Simultaneously, the movement of control block 602 causes counterweight block 607 to move closer to control block 602, thereby reducing the air pressure inside movable cavity 605. This reduces the pressure value felt by the baffle plate pressing against adjusting plate 611. Under the action of gravity, adjusting plate 611 moves downward, thereby causing the overall rotation direction of adjusting part 8, reducing the illumination range and preventing the light from affecting maintenance personnel. When thieves directly remove the cover 1, the process of clamping plate 702 pushing sealing plate 704 back into pressure accumulator 501 will cause the pressure inside pressure accumulator 501 to reach the preset pressure value. Therefore, warning tube 503 will issue a warning signal to warn thieves and alert other personnel. At the same time, the air pressure inside pressure accumulator 501 prevents sealing plate 704 from detaching from clamping plate 702, thus ensuring the locking and fixing effect of clamping plate 702 and sealing plate 704, preventing thieves from opening cover 1 and stealing the internal structure.
[0042] The adjustment unit 8 includes: a rotating rod 801, multiple rotating rods 801 rotatably connected inside the lamp housing 2; louvers 802, multiple louvers 802 fixedly connected to the outside of the rotating rods 801 for adjusting the direction of light illumination; when the angle of the louvers 802 changes, the direction of light illumination also changes; and connectors 803, the tops of multiple connectors 803 fixedly connected to the bottom of the adjustment plate 611, and their bottoms hinged to one side of the top of the uppermost louver 802 for cooperating with the adjustment plate 611 to drive the rotating rods 801 to rotate. The connectors 803 can be a pull rope structure and are located in the connecting... If the gravity on one side of the louver 802 at the connector 803 is greater than that on the other side of the rotating rod 801, then when the adjusting plate 611 moves upward, it will cause the multiple louvers 802 to tilt upward through the connector 803. Similarly, when the adjusting plate 611 moves downward under the action of gravity, the pulling force of the adjusting plate 611 on the multiple louvers 802 through the connector 803 will decrease, and the louvers 802 will swing downward under their own weight. The hinge rod 804 is movably hinged to one side of the multiple louvers 802 and is used to drive the multiple louvers 802 to rotate synchronously, thereby achieving precise adjustment of the direction of light illumination.
[0043] After installation, the position of the adjustment plate 611 can be changed by the operation of the control unit 6. The adjustment plate 611 is fixedly connected to the top of the connector 803, and the bottom of the connector 803 is hinged to the top of one side of the uppermost louver 802, thereby driving the uppermost louver 802 to rotate around the rotating rod 801. The louver 802 changes its angle, thereby changing the direction of light illumination. At the same time, the hinge rod 804 hinges multiple louvers 802, so multiple louvers 802 will be driven to rotate synchronously, so that the landscape light emits light in the preset direction. When the landscape light tilts due to long-term use or the influence of harsh external environment, the counterweight 607 inside the control unit 6 senses the change in gravity and moves, thereby causing the adjustment plate 611 to change position through the change in air pressure inside the adjustment cavity 612. After tilting, the louver 802 on the lower side will be driven to expand the illumination range, and the louver 802 on the higher side will be driven to reduce the illumination range, so that the overall illumination range of the landscape light remains unchanged, and the illumination direction of the landscape light will not cause glare to pedestrians.
[0044] A landscape light, which uses the aforementioned energy-saving park landscape light cover, further includes: a light post 3, which is fixedly connected to the bottom of the light housing 2 for fixing to the ground during installation; and a light body 4, which is fixedly installed inside the cover 1 for emitting light.
[0045] During the installation of the landscape light, the clamping plate 702 on the lamp housing 2 is inserted into the slot 701 on the cover 1. Then, the cover 1 and the lamp housing 2 are clamped and fixed by rotation. The gas is pressurized into the accumulator chamber 501 through the air inlet 502. The gas is a mixture of nitrogen and carbon dioxide, which can achieve a good sealing effect. The mixed gas is an inert gas and does not easily react with the outside air. The pressurization pressure is less than the preset pressure value. Due to the pressure in the accumulator chamber 501, the sealing plate 704 is pushed out of the accumulator chamber 501 and fills and seals the empty space in the slot 701, thereby sealing the cover 1 and the lamp housing 2 and preventing external dust, insects and other impurities from entering the landscape light and causing adverse effects.
[0046] The increased pressure inside the accumulator chamber 501 causes the counterweight 607 to move under the action of air pressure. The elastic element 606 is stretched, and rotating the handle 604 causes the adjusting rod 603 to rotate. The adjusting rod 603 is threadedly connected to the control block 602. Therefore, the rotation of the adjusting rod 603 causes the control block 602 to move in the direction of the adjusting rod 603, thereby stretching or retracting the guide body 609 fixedly connected to the control block 602. The guide body 609 causes the counterweight 607 to move within the movable cavity 605. The movement of the counterweight 607 causes the movable cavity 605 to move. The air pressure inside the moving cavity 605 decreases or increases, thereby causing the adjusting plate 611 to move up and down inside the moving cavity 605 under the action of air pressure. The adjusting plate 611 drives the connecting piece 803 to move up and down, and the connecting piece 803 drives the uppermost louver 802 to rotate around the rotating rod 801. Multiple louvers 802 are hinged together by the hinge rod 804, so they will rotate synchronously. Through the above process, the louvers 802 can be set to a predetermined direction for light to shine. Similarly, when it is necessary to change the direction of the louvers 802 in different positions, it is only necessary to adjust the control part 6 at the corresponding position.
[0047] by Figure 2 Taking the direction as an example, when the landscape light is used for a long time or is affected by external wind force and tilts at a slight angle, since there is inevitably a certain friction between the counterweight 607 and the movable cavity 605, the counterweight 607 will not move inside the movable cavity 605, and the corresponding internal structure of the cover 1 will not work, so as to avoid the external wind force causing the cover 1 to shake slightly and affect the stability of the internal structure.
[0048] When the external environment is harsh and the cover 1 tilts at a certain angle, the weight of the counterweight 607 is greater than the friction between the movable cavity 605 and the connecting hole 504. Therefore, the counterweight 607 set inside the cover 1 will change position due to the change in the angle of the cover 1. That is, when the landscape light tilts to the left, the counterweight 607 set behind the landscape light will squeeze the elastic element 606 to move to the left, thereby increasing the air pressure inside the movable cavity 605. This air pressure enters the adjustment cavity 612, and the air pressure acting on the bottom of the baffle plate will cause the adjustment plate 611 to move upward. The adjustment plate 611 drives the connecting piece 803 to move upward. The bottom of the connecting piece 803 drives the uppermost louver 802 to swing counterclockwise around the rotating rod 801, thereby causing the light passing through the louver 802 to move upward.
[0049] Meanwhile, the counterweight 607 located in front of the landscape light moves to the left, which reduces the air pressure inside the movable cavity 605. The counterweight 607 moves to the left simultaneously, further reducing the pressure inside the movable cavity 605. Under the action of gravity, the adjusting plate 611 moves downward, thereby causing the connecting piece 803 to move downward under the gravity of the uppermost louver 802. All the louvers 802 rotate clockwise around the rotating rod 801, causing the light passing through the louvers 802 to move downward. This process keeps the overall illumination range of the landscape light unchanged and causes the louvers 802 on the side opposite to the tilt direction of the landscape light to rotate downward, thus avoiding the landscape light from causing glare to passersby. In addition, because the tilt angle is small, the displacement distance of the counterweight 607 is small, and the pressure value inside the pressure accumulator 501 will not reach the preset pressure value and issue a warning signal. Similarly, when the landscape light is tilted at different angles, the control unit 6 at the corresponding position will drive the adjusting unit 8 at the corresponding position to change the rotation direction.
[0050] During the above process, if the tilt angle of the landscape light increases further, the sealing plate 704 moves in the opposite direction along the slot 701 and enters the pressure accumulator 501, reducing the locking effect on the plate 702. During this process, the counterweight 607 moves further to the left along the movable cavity 605, increasing the air pressure inside the movable cavity 605 and causing the adjusting plate 611 to move upward along the adjusting cavity 612 to the maximum distance. The adjusting plate 611 can no longer drive the louver 802 to rotate around the rotating rod 801 through the connector 803, and the opening angle of the louver 802 reaches its maximum value. At the same time, the air pressure inside the movable cavity 605 increases and reaches the pressure accumulator 501 through the connecting hole 504. The air pressure in the pressure accumulator 501 increases and applies a greater force to the sealing plate 704 to the right, effectively preventing the sealing plate 704 from sliding to the left under its own weight and reducing the locking effect with the plate 702, thus improving the sealing effect of the cover 1 in a large tilt state.
[0051] Similarly, the sealing plate 704 on the right moves to the left under its own weight and increases the locking effect with the clamping plate 702, thereby ensuring the overall sealing of the cover 1. At the same time, the counterweight 607 on the right moves to the left and is elastically limited by the elastic element 606. The air pressure inside the movable cavity 605 decreases and the thrust applied to the adjusting plate 611 through the adjusting cavity 612 decreases. The adjusting plate 611 on the right moves downward under its own weight, and the multiple louvers 802 on the right continue to rotate downward to avoid dazzling the surrounding people.
[0052] However, when the tilt angle of the cover 1 increases further and there is a risk of tipping over, the counterweight 607 will be displaced a large distance along the movable cavity 605 due to gravity. Therefore, the gas inside the movable cavity 605 will further enter the pressure storage cavity 501 through the connecting hole 504. When the pressure value inside the pressure storage cavity 501 reaches the preset pressure value, the pressure sensor installed inside the warning tube 503 will detect that the pressure value has reached the preset pressure value. The alarm inside the warning tube 503 will be activated and a warning signal will be issued. The warning signal can remind passers-by to stay away from the tilting range of the landscape light to prevent injury and can also remind staff to repair the landscape light in time to restore it to its original state.
[0053] When a component inside the cover 1 is damaged, the cover 1 needs to be removed. The operator can first rotate the handle 604 to drive the adjusting rod 603 to rotate. The adjusting rod 603 is threaded to the cover 1 and drives the control block 602 to move, thereby causing the guide body 609 to drive the counterweight 607 to move. The air pressure inside the movable cavity 605 decreases and applies a suction force to the pressure accumulator 501 through the connecting hole 504. Due to the movement of the counterweight 607, the air pressure inside the pressure accumulator 501 decreases, and the thrust exerted by the air pressure inside the pressure accumulator 501 on the sealing plate 704 decreases. Then, by rotating the cover 1, the clamping plate 702 is disengaged from the clamping slot 701. During this process, the sealing plate 704 squeezes the pressure accumulator 501 but does not cause the internal pressure of the pressure accumulator 501 to reach the preset pressure value, so no warning signal is issued.
[0054] At the same time, the movement of the control block 602 will cause the counterweight block 607 to move closer to the control block 602, thereby reducing the air pressure inside the movable cavity 605. The pressure value felt by the baffle plate on the adjustment plate 611 will decrease. Under the action of gravity, the adjustment plate 611 will move downward, thereby driving the adjustment part 8 to rotate in the same direction, reducing the illumination range and avoiding the light from affecting maintenance personnel.
[0055] However, when thieves illegally remove the landscape light cover 1, rotating the cover 1 without depressurizing the pressure accumulator 501 through the control unit 6 will cause the sealing plate 704 to retract partially into the pressure accumulator 501, thereby causing the internal pressure of the pressure accumulator 501 to reach the preset pressure value. The warning tube 503 will open and issue a warning signal to alert thieves and simultaneously remind passersby and staff. During this process, the air pressure inside the pressure accumulator 501 exerts a reverse force on the sealing plate 704, causing it to be locked and fixed to the clamping plate 702. Therefore, simply rotating the cover 1 cannot achieve separation from the light housing 2, further improving the overall anti-theft performance.
