Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular to an LED floodlight with a precisely adjustable light-emitting angle. Background Art

[0002] LED floodlights, due to their high efficiency, energy efficiency, and long lifespan, have become an indispensable component of modern lighting design and are widely used in various applications. These LED floodlights are commonly used to display exhibits, illuminate corridors, decorate building facades, and illuminate billboards and sculptures. Through appropriate lighting design, LED floodlights can highlight the unique charm of a building, enhance the visual impact, and thus attract more visitors and tourists.

[0003] While the various LED floodlights on the market have a wide range of applications, the light-guiding area of ​​most current products is typically fixed. This design limits the ability to adjust the LED chip's beam angle range. Due to the lack of a flexible adjustment mechanism, these LED floodlights cannot adjust the beam angle range to meet actual usage requirements. This means that in certain situations, they may not fully meet lighting needs, resulting in unsatisfactory lighting effects. Furthermore, the fixed light-guiding design makes the installation and maintenance of LED floodlights cumbersome. Users often have to disassemble the equipment when replacing or adjusting the LED floodlight, increasing the risk of damage and maintenance costs.

[0004] Therefore, to address this problem, it is urgent to develop an LED floodlight with an adjustable light-emitting angle to improve its functionality, flexibility and user-friendliness, so that it can better meet the lighting needs in different environments, thereby providing more efficient and beautiful lighting solutions for various scenes. Utility Model Content

[0005] In order to develop an LED floodlight with an adjustable light-emitting angle, the present application provides an LED floodlight with a precisely adjustable light-emitting angle.

[0006] The present application provides an LED floodlight with a precisely adjustable light-emitting angle, which adopts the following technical solutions:

[0007] An LED floodlight with a precisely adjustable luminous angle comprises a lamp housing, a lamp panel assembly and a lens assembly arranged in the lamp housing. The lamp panel assembly is fixedly installed in the lamp housing, and the lens assembly is movably installed in the lamp housing via a rotating mechanism. The rotating mechanism adjusts the distance from the lens assembly to the lamp panel assembly by rotating itself to adjust the luminous angle of the LED floodlight.

[0008] By adopting the above technical solution, the distance between the light panel and the lens assembly is adjusted through the rotating mechanism. When the distance between the light panel assembly and the lens assembly is the shortest, the light is converged through the lens and the luminous angle is the largest, which is suitable for long-distance lighting, focused lighting or special effect lighting. When the distance between the light panel assembly and the lens assembly increases, the luminous angle gradually decreases and the light is dispersed, which is suitable for a wide range of lighting needs, thereby enabling users to flexibly adjust the luminous angle according to specific lighting needs, effectively improving the lighting effect, avoiding light waste, making the light more concentrated or dispersed, and providing a more efficient lighting solution; and this design simplifies the operation of the LED floodlight, and users can easily adjust the luminous angle without disassembling the LED floodlight, thereby improving the convenience and safety of use.

[0009] In a specific possible implementation scheme, the rotating mechanism includes two groups of rotating parts and a transmission shaft connecting the two groups of rotating parts. The rotating parts are arranged on both sides of the lens assembly and are movably connected to the lens assembly. The lens assembly is driven to move by the rotation of the rotating parts, and the moving direction of the lens assembly is perpendicular to the axial direction of the transmission shaft.

[0010] By adopting the above technical solution, when the rotating part rotates, due to its movable connection with the lens assembly, the movement of the rotating part will be transmitted to the lens assembly. The rotation of the rotating part causes the lens assembly to move in a direction perpendicular to the axis of the transmission shaft, thereby adjusting the distance between the lens assembly and the light board assembly to change the luminous angle of the LED floodlight.

[0011] In a specific possible implementation scheme, the rotating part includes a component fixing plate, a transmission plate, and a crank. The component fixing plate is fixed in the lamp housing. The transmission plate is movably connected to the component fixing plate. The crank first passes through the transmission plate and then through the component fixing plate to be connected to the transmission shaft. The transmission plate is movably connected to the lens assembly, and the crank is rotatably arranged. By rotating the crank, the transmission plate and the lens assembly are driven to move, so that the position of the transmission plate relative to the component fixing plate changes, and the position of the lens assembly relative to the transmission plate changes.

[0012] By adopting the above technical solution, the position of the transmission plate and the lens assembly can be precisely controlled through the rotation of the crank, so that the focus and divergence angles of the light beam can be finely adjusted according to needs. The movable connection design between the transmission plate and the component fixing plate and the lens assembly allows the lens assembly to be moved and adjusted, thereby enhancing the flexibility of the system to adapt to different lighting needs and scenarios.

[0013] In a specific feasible implementation scheme, the crank includes a rotating part and a swing arm part, and the transmission plate is provided with a crank slot, a swing arm slot, a lens slot, and an installation slot, the swing arm slot and the installation slot are respectively located on both sides of the crank slot, and the lens slot is arranged on the same side as the swing arm slot; the rotating part first passes through the crank slot and then passes through the component fixing plate to be connected to the transmission shaft, the rotating part is slidably connected to the crank slot, the swing arm part is inserted into the swing arm slot and slidably connected to the swing arm slot; the lens assembly is provided with a connecting part, the connecting part is inserted into the lens slot and slidably connected to the lens slot; the component fixing plate is provided with a mounting part, the mounting part is inserted into the mounting slot and slidably connected to the mounting slot.

[0014] By adopting the above technical solution, one of the cranks is rotated, and the crank drives the transmission shaft to rotate, and the transmission shaft drives the other crank to rotate. During the rotation of the crank, the rotating part of the crank slides relative to the transmission plate through the crank slot. While the rotating part rotates, the swing arm part is embedded in the swing arm slot and slidably connected. The sliding action of the swing arm part can transmit the force of the rotating part, so that the swing arm drives the transmission plate to produce displacement in the swing arm slot, pushing the transmission plate to one side. As the transmission plate moves, the connecting part on the lens assembly is inserted into the lens slot, and the sliding connection with it can ensure that the lens assembly follows the movement of the transmission plate, and the position of the lens assembly is changed, thereby adjusting the luminous angle; through the multi-directional layout design of the crank and the slot, the rotating part and the swing arm part can efficiently transmit motion, thereby realizing flexible adjustment of the transmission plate and the lens assembly, thereby realizing control of the luminous angle.

[0015] In a specific feasible implementation scheme, the moving direction of the swing arm part in the swing arm slot is perpendicular to the axial direction of the transmission shaft, the moving direction of the rotating part in the crank slot is perpendicular to both the moving direction of the swing arm part in the swing arm slot and the axial direction of the transmission shaft, and the moving direction of the rotating part in the crank slot is the same as the moving direction of the mounting part in the mounting slot.

[0016] By adopting the above technical solution, the movement direction relationship between each component is reasonably designed, so that the system can achieve multi-directional coordinated movement, which not only improves the efficiency, accuracy and stability of the system, but also simplifies the structure and maintenance.

[0017] In a specific possible implementation manner, the lens sliding groove is an arc-shaped groove, and the angle of the arc-shaped groove is 20°-50°.

[0018] By adopting the above technical solution, the arc design of the lens slide allows the lens assembly to move freely at different angles and positions, and can adjust a variety of lighting angles to adapt to different working conditions.

[0019] In a specific embodiment, a stop spring is further included. The stop spring is provided on the component fixing plate, and the stop spring is used to contact the swing arm part to limit the movement of the swing arm part.

[0020] By adopting the above technical solution, the main function of the stop spring is to contact the swing arm part, thereby limiting its range of movement. This limitation can control the movement of the swing arm to ensure that it operates within the design range and avoid mechanical damage or failure of the optical system caused by excessive movement.

[0021] In a specific embodiment, it further includes a rotating head and a decorative cover, wherein the decorative cover is fixed to the lamp housing, the rotating head is installed in the decorative cover, one end of the rotating head is located in the decorative cover, and the other end is connected to the crank.

[0022] By adopting the above technical solution, the design of the rotating head makes the adjustment of the light source more flexible. Users can easily control the direction of the light by rotation to achieve precise lighting effects; the presence of the decorative cover not only provides the device with an aesthetically pleasing appearance, but also protects the internal mechanical components to prevent the entry of dust and debris.

[0023] In a specific embodiment, the rotating head is provided with a rotating operation slot, and the rotating operation slot is used for inserting a tool to rotate the rotating head.

[0024] By adopting the above technical solution, the design of the rotary operation slot simplifies the operation process of the rotary head, allowing users to easily use common tools for adjustment and avoid dependence on complex equipment.

[0025] In a specific possible implementation scheme, the decorative cover is provided with an angle mark, and the rotating operation slot is used in conjunction with the angle mark; the rotating operation slot is rotated to the corresponding angle mark to indicate the luminous angle of the LED floodlight at this position.

[0026] By adopting the above technical solution, the user can clearly know the current luminous angle of the lens assembly through the indication of the angle mark, which improves the accuracy and reliability of the adjustment. The angle mark provides clear visual feedback to help users quickly judge the current settings and avoid misoperation. This design simplifies the operation process and reduces the difficulty of operation.

[0027] In a specific possible implementation scheme, it also includes a power and color temperature controller and a light control belt DIP switch component. The power and color temperature controller and the light control belt DIP switch component are arranged in the lamp housing and electrically connected to the lamp board component.

[0028] By adopting the above technical solution, through the integrated power and color temperature controller, and the light control with DIP switch component, users can freely adjust the brightness and color temperature of the LED floodlight according to different scenarios and needs, which not only improves the functionality and adaptability of the LED floodlight, but also optimizes the user's operating experience.

[0029] To sum up, the beneficial technical effects of the present application are: by rotating the rotating mechanism, the lens assembly is moved to adjust the distance between the lamp panel assembly and the lens assembly. When the distance between the lamp panel assembly and the lens assembly is closest, the light is converged by the lens and the luminous angle is the largest, which is suitable for long-distance lighting, focused lighting or special effect lighting. When the distance between the light panel assembly and the lens assembly increases, the luminous angle gradually decreases and the light is dispersed, which is suitable for a wide range of lighting needs; thereby, users can flexibly adjust the luminous angle according to specific lighting needs, thereby effectively improving the lighting effect, avoiding waste of light, making the light more concentrated or dispersed, and providing a more efficient lighting solution. In addition, this design simplifies the operation of the LED floodlight, and users can easily adjust the luminous angle without disassembling the LED floodlight, thereby improving the convenience and safety of use.

[0044] In actual adjustment operations, the user can adjust the distance between the light panel assembly 2 and the lens assembly 3 by rotating the rotating mechanism 4 to move the lens assembly 3. When the distance between the light panel assembly 2 and the lens assembly 3 is closest, the light is converged through the lens and the luminous angle is the largest, which is suitable for long-distance lighting, focused lighting or special effect lighting.

The transmission plate 52 is movably connected to the assembly fixing plate 51, and the crank 53 first passes through the transmission plate 52 and then through the assembly fixing plate 51 to be connected to the transmission shaft 6. The crank 53 is rotatably arranged, and the transmission plate 52 is movably connected to the lens assembly 3; by rotating the crank 53, the transmission plate 52 and the lens assembly 3 are driven to move, so that the position of the transmission plate 52 relative to the assembly fixing plate 51 changes, and the position of the lens assembly 3 relative to the transmission plate 52 changes;

[0047] The rotation of the crank 53 can precisely control the position of the transmission plate 52 and the lens assembly 3, so that the focus and divergence angles of the light beam can be finely adjusted as needed. The movable connection design between the transmission plate 52 and the assembly fixing plate 51 and the lens assembly 3 allows the lens assembly 3 to be moved and adjusted, enhancing the flexibility of the system to adapt to different lighting needs and scenarios.

[0048] The crank 53 includes an integrally formed rotating portion 531 and a swing arm portion 532. The transmission plate 52 is provided with a crank slot 54, a swing arm slot 55, a lens slot 56, and an installation slot 57.

In this embodiment, two lens slots 56 are provided, and the two lens slots 56 are respectively located on both sides of the swing arm slot 55. The lens slot 56 is an arc slot with an angle of 20°-50°. The arc design of the lens slot 56 allows the lens assembly 3 to move freely at different angles and positions, thereby achieving adjustment of various light-emitting angles to adapt to different working conditions.

During the rotation of the crank 53, the rotating portion 531 of the crank 53 slides relative to the transmission plate 52 through the crank slot 54. When the rotating portion 531 rotates, the swing arm portion 532 is inserted into the swing arm slot 55 and slidably connected.

The stop spring piece 7 is used to contact the swing arm part 532 to limit the movement of the swing arm part 532; the main function of the stop spring piece 7 is to contact the swing arm part 532, thereby limiting its range of movement. Through this limitation, the movement of the swing arm can be controlled to ensure that it operates within the design range, avoiding mechanical damage or failure of the optical system caused by excessive movement.

The angle mark 81 provides clear visual feedback to help the user quickly judge the current setting and avoid misoperation. This design simplifies the operation process and reduces the difficulty of operation.

[0059] Reference Figure 6 and Figure 7 In this embodiment, the luminous angle of the LED floodlight includes but is not limited to three gears: 55°, 75°, and 90°. When the rotating operating slot 91 is rotated to the angle mark 81 of the luminous angle of 90°, the connecting portion 31 of the lens assembly 3 abuts against the bottom end of the lens slide groove 56, the swing arm portion 532 of the crank 53 abuts against the bottom end of the swing arm slide groove 55, the rotating portion 531 of the crank 53 abuts against the rightmost end of the crank slide groove 54, and one of the mounting portions 511 of the component fixing plate 51 abuts against the rightmost end of the mounting slide groove 57.

[0063] In this embodiment, the power and color temperature controllers are integrated into the power supply 16. Power regulation is achieved by adjusting the output current through the DIP switch on the controller and the power supply 16. Color temperature regulation is achieved by controlling the light intensity of multiple LED lamp beads with different color temperatures through the DIP switch on the controller, and mixing the light to achieve the purpose of changing the color temperature. This allows users to freely adjust the brightness and color temperature of the LED floodlight according to different scenarios and needs, which not only improves the functionality and adaptability of the LED floodlight, but also optimizes the user's operating experience.

[0064] In this embodiment, the customer can freely choose whether to enable the light control function with a switch function, thereby facilitating the control of the switch and light control function of the LED floodlight, which not only improves the convenience of using the LED floodlight, but also automatically adjusts the working state of the LED floodlight according to environmental needs, thereby enhancing energy efficiency and user experience.

[0065] The working principle of the embodiment of the present application is as follows: when the lighting angle needs to be adjusted, the rotating operation slot 91 on the rotating head 9 is rotated to the corresponding angle mark 81 on the decorative cover 8 according to the desired lighting angle; during this process, the user can insert a tool into the rotating operation slot 91 to rotate the rotating head 9, and the rotating head 9 drives the crank 53 connected to it to rotate, and the rotating portion 531 of the crank 53 drives the transmission shaft 6 to rotate, and the transmission shaft 6 drives the other crank 53 to rotate;

[0066] When the crank 53 rotates, the rotating portion 531 of the crank 53 slides relative to the transmission plate 52 through the crank slot 54. When the rotating portion 531 rotates, the swing arm portion 532 is inserted into the swing arm slot 55 and slidably connected. The sliding action of the swing arm portion 532 can transmit the force of the rotating portion 531, so that the swing arm drives the transmission plate 52 to generate displacement in the swing arm slot 55, pushing the transmission plate 52 to move forward and backward in a plane. As the transmission plate 52 moves, the connecting portion 31 on the lens assembly 3 is inserted into the lens slot 56 and the sliding connection therewith can ensure that the lens assembly 3 follows the movement of the transmission plate 52. The lens assembly 3 moves up and down in a plane. The position of the lens assembly 3 is changed, thereby achieving the effect of adjusting the distance between the lens assembly 3 and the lamp board assembly 2, thereby achieving the effect of adjusting the luminous angle of the LED floodlight.

[0067] This application mainly adjusts the distance between the lamp panel and the lens assembly 3 through the rotating mechanism 4, so that the user can flexibly adjust the light-emitting angle according to specific lighting needs, thereby effectively improving the lighting effect, avoiding waste of light, making the light more concentrated or dispersed, and providing a more efficient lighting solution; and this design simplifies the operation of the LED floodlight, and the user can easily adjust the light-emitting angle without disassembling the LED floodlight, thereby improving the convenience and safety of use.
