Description

Technical Field

[0001] This invention relates to the field of floodlight technology, specifically to a floodlight with an adjustable projection angle. Background Technology

[0002] A floodlight is a lighting fixture designed to provide illumination on a surface higher than the surrounding environment. Also known as a spotlight, it can typically be aimed in any direction and is unaffected by weather conditions. It is primarily used for large-area work sites, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area outdoor lighting fixtures can be considered floodlights. Floodlights have varying beam angles, ranging from 0° to 180°, with those having particularly narrow beams being called searchlights. A floodlight consists of three parts: optical components, mechanical components, and electrical components. The optical components mainly include reflectors and light-blocking grates. The mechanical components primarily consist of the housing, focusing mechanism for fixing and adjusting the light source position, brackets and bases for fixing the fixture, and parts with angle indicators for adjusting the beam direction. For most enclosed floodlights, the mechanical components also include protective glass and various sealing rings. Depending on the environment, some also have metal mesh covers. High-performance floodlights are also equipped with air filters. The electrical components mainly include ballasts, capacitors, and triggers (depending on the light source requirements).

[0003] Existing floodlights have screws on both sides of the lamp body that connect to a bracket on the back. The lamp body is fixed by the bracket on the back, and the screws on both sides of the lamp body are used to fix the angle of the floodlight. The angle of the floodlight can only be adjusted by rotating around the screws on both sides as an axis and then fixed. The angle cannot be adjusted to the left or right, etc. The adjustable illumination range is small, which has significant shortcomings in use. Furthermore, since the lamp body and the connecting bracket are integrated, it is also quite troublesome to replace the floodlight if the bulb burns out or other malfunctions occur. Summary of the Invention

[0004] The purpose of this invention is to provide a floodlight with an adjustable projection angle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a floodlight with adjustable projection angle, comprising a movable rail, a lifting block slidably disposed within the movable rail, a lead screw penetrating through the lifting block, two support plates mounted on the side wall of the lifting block, a cable winding assembly disposed on the top surface of the support plates, an installation block connected to the end of the support plates, a first docking post movably disposed within the installation block, a floodlight head easily disassembled and assembled at one end of the first docking post, a tail post disposed at the other end of the first docking post, a protruding post mounted on the tail post, an installation frame mounted on the installation block, and an adjustment assembly for adjusting the illumination direction of the floodlight head disposed on the installation frame.

[0006] Preferably, the movable rail is provided with fixing ears on both sides, and the fixing ears can be fixed in the installation position using bolts.

[0007] Preferably, the lifting block is provided with a threaded hole, the lead screw is connected to the threaded hole, and the end of the lead screw is connected to a lifting motor.

[0008] Preferably, the take-up assembly includes a take-up box, inside which a winding post is installed. The winding post is a hollow cylindrical structure with a protruding edge at its upper end. Inside the winding post, a first push rod is installed. At the top of the first push rod, a winding motor is installed. At the output end of the winding motor, a winding rod is installed. The winding rod is a downwardly bent rod, and at the bottom end of the winding rod, a lead ring is provided.

[0009] Preferably, the mounting block has a spherical cavity inside, a sphere is disposed in the middle of the docking post, the sphere is located inside the spherical cavity, and the spherical cavity is provided with damping.

[0010] Preferably, the floodlight head is provided with a second docking post, which is inserted into the end of the first docking post. The end face of the second docking post inserted into the first docking post is provided with a groove. A sealing groove is provided on the side wall of the second docking post. An inner cavity is provided inside the first docking post. An elastic airbag column is provided inside the inner cavity. A pressure rod is fixedly connected to the end of the elastic airbag column. The pressure rod is movably connected to the first docking post. The end of the pressure rod abuts in the groove of the second docking post. A sealing airbag is provided inside the first docking post. The sealing airbag corresponds to the sealing groove and is connected to the elastic airbag column.

[0011] Preferably, the protruding post is rotatably inserted into the end of the tail post.

[0012] Preferably, the adjustment assembly includes an adjustment motor installed in the middle of the mounting frame, with a mounting plate rotatably sleeved at the end of the adjustment motor, the output end of the adjustment motor connected to the mounting plate, a second push rod fixedly installed on the side wall of the mounting plate, a pull plate provided at the end of the second push rod, and a traction belt connected between the pull plate and the protruding post.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The present invention proposes an adjustable floodlight with adjustable projection angle. The installation height of the device can be adjusted arbitrarily, making it more versatile. It is equipped with a wire take-up component to facilitate the storage of excess wires, making it more convenient to use. Furthermore, because it is equipped with a floodlight head that is easy to disassemble and assemble, it is also convenient to replace parts if the device is damaged. In addition, because it is equipped with an adjustment component for adjusting the illumination direction of the floodlight head, it can greatly increase the projection range of the device, making it more practical.

[0015] 2. By controlling the rotation of the lifting motor, the lead screw can be rotated. When the lead screw rotates inside the lifting block, the lifting block can move up and down within the movable rail, thereby driving the entire equipment to move and allowing the equipment to be moved to the required installation height.

[0016] 3. Because the equipment needs to move up and down, the connected wires must be set to the maximum required length. When the equipment moves to the lowest or highest end, it is close to the power supply, which will result in too much wire remaining. It needs to be collected in time. The wires enter the take-up box and the ends are fixedly connected to the equipment. The wires pass through the lead ring. The winding motor drives the winding rod and lead ring to rotate so that the wires are wound on the winding column. The first push rod can drive the winding motor to move up and down, so that the winding of the wires is more even.

[0017] 4. When installing the floodlight head, simply insert the second docking post into the first docking post, aligning the plug and socket. The groove wall pushes the pressure rod forward, compressing the elastic airbag column. The gas inside the elastic airbag column enters the sealing airbag, which expands and embeds itself into the sealing groove. Because the floodlight head itself is lightweight, the second docking post is snapped into place, ensuring a secure installation. The gaps at the connection are sealed by the sealing airbag, providing a good seal and preventing water from entering the connection and causing short circuits. Disassembly is easy; simply pull the floodlight head outwards.

[0018] 5. When it is necessary to adjust the orientation of the floodlight head, such as when the floodlight head needs to swing downwards, simply control the adjusting motor to drive the mounting plate to rotate, causing the second push rod to move upwards. Then, control the second push rod to extend and push the pull plate upwards, thereby pulling the protrusion upwards and causing the floodlight head to swing downwards. This adjusts the projection angle of the floodlight head. The degree to which the floodlight head points downwards depends on the degree to which the pull plate pulls the protrusion upwards. The mounting plate can rotate at a certain angle, providing a wide adjustment range and making it more practical. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1 to 6 This invention provides a technical solution: an adjustable floodlight, including a movable rail 1. Only a section of the movable rail 1 is shown in the figure; its total length depends on the required installation height. Fixing ears are provided on both side walls of the movable rail 1, which can be fixed in the installation position using bolts. A lifting block 2 is slidably disposed within the movable rail 1, and a lead screw 3 is threaded through the lifting block 2. The lifting block 2 has a threaded hole, and the lead screw 3 is connected to the threaded hole. A lifting motor is connected to the end of the lead screw 3. By controlling the rotation of the lifting motor, the lead screw 3 can be rotated. When the lead screw 3 rotates within the lifting block 2, the lifting block 2 can move up and down within the movable rail 1, thereby moving the entire device to the required installation height.

[0028] Two support plates 4 are installed on the side wall of the lifting block 2. A wire take-up assembly is provided on the top surface of the support plate 4. The wire take-up assembly can be installed on the top or the bottom, depending on the power supply location. The wire take-up assembly includes a wire take-up box 5. A winding column 6 is installed inside the wire take-up box 5. The winding column 6 is a hollow cylindrical structure with a protruding edge at the upper end. A first push rod 7 is installed inside the winding column 6. A winding motor 8 is installed at the top of the first push rod 7. A winding rod 9 is installed at the output end of the winding motor 8. The winding rod 9 is a downwardly bent rod. A guide is provided at the bottom end of the winding rod 9. Wire loop 10; Because the equipment needs to move up and down, the connected wires must be set according to the longest required length. When the equipment moves to the lowest or highest end, it is close to the power supply, which will result in too much wire remaining, which needs to be collected in time. The wires enter the take-up box 5 and the end will be fixedly connected to the equipment. The wires pass through the lead loop 10. The winding motor 8 drives the winding rod 9 and the lead loop 10 to rotate, so that the wires can be wound on the winding post 6. The first push rod 7 can drive the winding motor 8 to move up and down, so that the winding of the wires is more even.

[0029] The support plate 4 is connected to the end of the mounting block 11. The first docking post 12 is movably disposed in the mounting block 11. The mounting block 11 has a spherical cavity inside. The first docking post 12 has a sphere 1201 in the middle. The sphere 1201 is located inside the spherical cavity. Therefore, the first docking post 12 can move relative to the mounting block 11. The angle adjustment range is very large. The spherical cavity is equipped with damping. If the first docking post 12 is not affected by external force, it will not move arbitrarily.

[0030] One end of the first docking post 12 is provided with a floodlight head 13 for easy assembly and disassembly. A second docking post 21 is provided on the floodlight head 13. The second docking post 21 is inserted into the end of the first docking post 12. The end face of the second docking post 21 inserted into the first docking post 12 is provided with a groove. A socket and a plug are provided at the connection between the end of the second docking post 21 and the first docking post 12. When the socket and plug are connected, the floodlight head 13 can be electrically connected to them. A sealing groove is provided on the side wall of the second docking post 21. An inner cavity 22 is provided inside the first docking post 12. An elastic airbag post 23 is provided inside the inner cavity 22. A pressure rod 24 is fixedly connected to the end of the elastic airbag post 23. The pressure rod 24 is movably connected to the first docking post 12. The end of the pressure rod 24 abuts against the groove of the second docking post 21. A sealing airbag 25 is provided inside the first docking post 12. The sealing airbag 25 corresponds to the sealing groove and is connected to the elastic airbag column 23. When installing the floodlight head 13, simply insert the second docking post 21 into the first docking post 12. The plug and socket are connected, and the groove wall pushes the pressure rod 24 forward, which compresses the elastic airbag column 23. The gas inside the elastic airbag column 23 enters the sealing airbag 25, and the sealing airbag 25 expands and embeds into the sealing groove. Because the floodlight head 13 itself is lightweight, the second docking post 21 is snapped in place, ensuring a stable installation. The gap at the connection is sealed by the sealing airbag 25, providing good sealing and preventing water from entering the connection and causing short circuits. Disassembly is easy; simply pull the floodlight head 13 outwards.

[0031] The other end of the first docking post 12 is provided with a tail post 14, and a protruding post 15 is installed on the tail post 14. The protruding post 15 is rotatably inserted into the end of the tail post 14. A mounting bracket 16 is installed on the mounting block 11, and an adjustment component for adjusting the illumination direction of the floodlight head 13 is provided on the mounting bracket 16. The adjustment component includes an adjustment motor 17 installed in the middle of the mounting bracket 16. A mounting plate 1701 is rotatably sleeved at the end of the adjustment motor 17. The output end of the adjustment motor 17 is connected to the mounting plate 1701. A second push rod 18 is fixedly installed on the side wall of the mounting plate 1701. A pull plate 19 is provided at the end of the second push rod 18. A traction belt 20 is connected between the pull plate 19 and the protruding post 15. When it is necessary to adjust the orientation of the floodlight head 13, such as when the floodlight head 13 needs to swing downwards... Simply control the adjusting motor 17 to drive the mounting plate 1701 to rotate, causing the second push rod 18 to move upward. Then, control the second push rod 18 to extend and push the pull plate 19 upward, thereby pulling the protrusion 15 upward, which causes the floodlight head 13 to swing downward, thus adjusting the projection angle of the floodlight head 13. The degree to which the floodlight head 13 points downward depends on the degree to which the pull plate 19 pulls the protrusion 15 upward. The mounting plate 1701 can rotate 360°, with a large adjustment range, making it more practical.
