Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular to a lamp. Background Art

[0002] High bay lighting is a lighting solution designed specifically for high-altitude locations. Its unique design and functionality make it particularly important. These lamps are typically installed high up in the ceiling, aiming to provide strong and uniform lighting for large venues, factories, warehouses, and more.

[0003] Traditional high-bay lights often feature a fixed beam angle design. This single-angle limitation may not meet the flexibility requirements for diverse lighting needs. Currently, two main solutions exist on the market to achieve beam angle adjustment: one is to change the beam angle by adjusting the distance between the lens and the LED light source; however, this approach can result in a loss of light efficiency and presents challenges in meeting waterproofing requirements. Another approach utilizes optical components with multiple beam angles and selects different lighting angles by controlling the on and off of the LED modules. While this design provides more options, it wastes LED resources and fixture space, increasing manufacturing and maintenance costs.

[0004] Therefore, it is urgent to develop a high bay light that can adjust the light output angle of the lamp without changing the appearance of the lamp, and can take into account the lighting effect, waterproof level and cost-effectiveness. Utility Model Content

[0005] In order to achieve an adjustable light output angle of a lamp while taking into account light efficiency, waterproof level and cost-effectiveness, the present application provides a lamp.

[0006] The present application provides a lamp that adopts the following technical solution:

[0007] A lamp comprises a lamp panel body and a lens plate and a lamp board installed in the lamp panel body, wherein the lens plate is provided with a spirally arranged lens, and a plurality of lamp beads are provided on a side of the lamp panel close to the lens, and the lamp beads are distributed in a spiral array; and further comprises a rotating part, which is used to drive the lens plate to rotate so that the relative position of the lens and the lamp beads changes.

[0008] By adopting the above technical solution, in actual use, the rotating part is controlled, and the rotating part drives the lens plate to rotate, and the angle of the lens on the lens plate is adjusted, thereby changing the relative position relationship between the lens and the lamp bead, thereby achieving the effect of changing the light-emitting angle; the present application uses the rotation of the lens to change the refraction path and focusing method of the light, thereby controlling the distribution shape, focus and illumination distribution of the light, thereby meeting different lighting needs, such as focusing on a specific area or providing wide-angle lighting, and realizing the adjustable light output angle of the lamp without changing the appearance of the lamp; and the rotation of the lens can optimize the focusing and dispersion effects of the light beam, thereby improving the lighting effect and optical performance, reducing light loss, and taking into account light efficiency, waterproof level and cost-effectiveness.

[0009] In a specific possible implementation manner, the spiral arrangement direction of the lens is the same as the spiral arrangement direction of the lamp bead.

[0010] By adopting the above technical solution, the spiral setting in the same direction reduces the errors or mismatches that may occur during the adjustment process, improves the stability and long-term reliability of the lamp; and can optimize the light propagation effect and energy utilization, providing a more uniform and efficient lighting effect while reducing energy waste.

[0011] In a specific possible implementation scheme, the rotating part includes a gear and a tooth groove structure provided on the lens plate, the tooth groove structure is arranged along the peripheral outer wall of the lens plate, the gear is installed on the lamp panel body and is rotatable, and the gear is engaged with the tooth groove structure.

[0012] By adopting the above technical solution, when working, the driving gear rotates. When the gear rotates, its teeth engage with the tooth-groove structure on the lens plate. The gear will engage and drive the lens plate to rotate, and the lens will rotate, thereby changing the relative position relationship between the lens and the lamp bead, thereby achieving the effect of changing the light-emitting angle; through the design of the gear and tooth-groove structure, the light-emitting angle can be adjusted, which improves the functionality and practicality of the lamp and provides users with a more flexible operating experience.

[0013] In a specific possible implementation scheme, it also includes a pressure plate, which is arranged on the side of the lens plate away from the lamp board, and the pressure plate is connected and fixed to the lamp panel body, thereby fixing the lens plate and the lamp board in the lamp panel body.

[0014] By adopting the above technical solution, the pressure plate is fixed by being connected to the lamp panel body, which can effectively fix the lens plate and the light board inside the lamp. This connection method ensures that the lens plate and the light board will not move or loosen due to vibration or external force during use, ensuring the stable operation of the lens plate and the light board during work and ensuring the stability of the lamp.

[0015] In a specific possible implementation scheme, the gear is provided with a rotating shaft, the rotating shaft passes through the gear, the lamp panel body is provided with a groove, the gear and one end of the rotating shaft are accommodated in the groove, the pressure plate is provided with a through hole, the other end of the rotating shaft is inserted into the through hole, and the rotating shaft rotates in the through hole and the groove.

[0016] By adopting the above technical solution and utilizing the design of grooves and through holes, the entire mechanical structure can provide precise rotation control, ensuring that the gears and rotating shafts maintain stable positions and motion trajectories during operation; and this design can enable the gears and related components to operate stably for a long time, reduce the possibility of wear and failure caused by friction and motion instability, and improve the stability and durability of the entire rotating part.

[0017] In a specific possible implementation scheme, a slot is provided on the rotating shaft, the slot is communicated with the through hole, and the slot is used for an operator to use a tool to rotate the gear.

[0018] By adopting the above technical solution, when in use, the operator uses a tool, inserts the tool into the slot through the through hole, and directly acts on the rotating shaft, thereby indirectly controlling the rotation of the gear; the slot design allows the operator to easily use the tool to adjust the rotation of the gear without directly contacting or affecting other components, thereby improving the accuracy and safety of the operation.

[0019] In a specific possible implementation manner, a sealing ring is further included, and the sealing ring is arranged between the lens plate and the lamp board. The pressure plate presses on the lens plate and forms pressure on the sealing ring.

[0020] By adopting the above technical solution and through effective sealing design, it is possible not only to limit the entry of the external environment, but also to protect internal components such as the lens plate and the light board from contamination or damage, thereby reducing maintenance and replacement costs; and it is also possible to improve the cleanliness and optical performance of the lens plate and the light board.

[0021] In a specific possible implementation scheme, the lens plate and the light board are provided with corresponding rotation limiting structures, and the lens plate is provided with several angle gears; when the lens plate rotates, the rotation limiting structures on the lens plate and the light board form a gear engagement at the angle gears.

[0022] By adopting the above technical solution, when the lens plate rotates, the rotation limit structure on the lens plate and the lamp board will engage at the corresponding angle gear. This engagement ensures that the lens plate can stay stably at each angle gear, preventing damage to the lamp beads due to excessive rotation; through the design of the rotation limit structure and angle gear, the operator can select and control the rotation angle of the lens plate to ensure that the light output meets the requirements, and by limiting the rotation range of the lens plate, the lamp beads are effectively protected from damage that may be caused by excessive rotation, thereby improving the functionality and operability of the lamp and ensuring long-term stable operation of the lamp.

[0023] In a specific possible implementation manner, the lens plate is further provided with an observation window, and the observation window is used to observe the angle position.

[0024] By adopting the above technical solution and utilizing the design of the observation window, the convenience and accuracy of operation are improved. The operator can directly confirm the selected angle gear through the observation window, thereby effectively managing and adjusting the optical characteristics of the lamp, thereby increasing the intuitiveness and controllability of the user's operation, making the adjustment of the lamp easier and more reliable.

[0025] In a specific possible implementation scheme, a heat sink is further provided in the lamp panel body.

[0026] By adopting the above technical solution and utilizing an internally designed radiator, the lamp can more effectively manage and disperse heat, thereby protecting the electronic components inside the lamp, such as lamp beads, from overheating, extending the service life of the lamp, and improving the stability and performance of the lamp during operation.

[0027] To sum up, the beneficial technical effects of the present application are as follows: the present application mainly utilizes the rotation of the lens to change the refraction path and focusing mode of the light, thereby controlling the distribution shape, focus and illumination distribution of the lamp light, so as to meet different lighting needs, such as focusing on a specific area or providing wide-angle lighting, and realizing the adjustable light output angle of the lamp without changing the appearance of the lamp; and by utilizing the rotation of the lens, the focusing and dispersion effects of the light beam can be optimized, thereby improving the lighting effect and optical performance, reducing light loss, and taking into account light efficiency, waterproof level and cost-effectiveness.

[0037] The following is combined with Figure 1-8 This application is described in further detail.

[0038] Reference Figure 1 , the embodiment of the present application discloses a lamp, the lamp includes but is not limited to a high bay lamp;

[0039] The lamp includes a lamp panel body 1. In this embodiment, a power supply module 14 is provided on the lamp panel body 1. The power supply module 14 is connected to the lamp panel body 1 by screws. An output line pressure plate 517 is provided between the lamp panel body 1 and the power supply module 14. In this embodiment, a hanging ring 15 is installed on the side of the power supply module 14 away from the lamp panel body 1. The hanging ring 15 is made of metal and is connected to the power supply module 14 by screws. In this embodiment, the hanging ring 15 is used for hanging the lamp.

[0040] The lamp also includes a lens plate 2 and a lamp board 3. A mounting groove 11 for accommodating the lens plate 2 and the lamp board 3 is provided in the lamp panel body 1. The lamp board 3 is first installed in the lamp panel body 1, and then the lens plate 2 is installed in the lamp panel body 1. A plurality of lamp beads 31 are provided on the side of the lamp board 3 near the lens 21. In this embodiment, the lamp beads 31 on the lamp board 3 are electrically connected to the power supply 14 via a connecting cable and are fixed in place by an output line pressure plate 517.

[0041] A plurality of lamp beads 31 are arranged in a spiral array on the lamp board 3. The lens board 2 is spirally provided with a lens 21 protruding toward the light-emitting surface. In this embodiment, the positions of the lamp beads 31 and the lens 21 correspond to each other. The longitudinal cross-section of the lens 21 is wavy. The lamp beads 31 are located within the lens 21, and the spacing between adjacent lamp beads 31 is the same.

[0042] The spiral setting direction of the lamp bead 31 is the same as the spiral setting direction of the lens 21. The spiral setting in the same direction reduces errors or mismatches that may occur during adjustment, improving the stability and long-term reliability of the lamp. It can also optimize the light propagation effect and energy utilization, providing a more uniform and efficient lighting effect while reducing energy waste.

[0043] The lamp further includes a pressure plate 5, which is disposed on a side of the lens plate 2 away from the lamp board 3. In this embodiment, the pressure plate 5 is fixed to the lamp panel body 1 by screws, thereby fixing the lens plate 2 and the lamp board 3 in the lamp panel body 1; the pressure plate 5 is connected to the lamp panel body 1 by bolts, effectively fixing the lens plate 2 and the lamp board 3 inside the lamp. This connection method ensures that the lens plate 2 and the lamp board 3 will not move or loosen due to vibration or external force during use, ensuring the stable operation of the lens plate 2 and the lamp board 3 during operation and ensuring the stability of the lamp.

[0044] Reference Figure 1 and Figure 2 The lamp further includes a rotating member 4. In this embodiment, the rotating member 4 is installed in the lamp panel body 1 and fixed in the lamp panel body 1 by a pressure plate 5. The rotating member 4 is rotatably arranged to drive the lens plate 2 to rotate, so that the relative position of the lens 21 and the lamp bead 31 changes;

[0045] During actual use, the rotating part 4 is controlled, and the rotating part 4 drives the lens plate 2 to rotate, adjusting the angle of the lens 21 on the lens plate 2, thereby changing the relative position relationship between the lens 21 and the lamp bead 31, thereby achieving the effect of changing the light-emitting angle; by utilizing the rotation of the lens 21 to change the refraction path and focusing mode of the light, the distribution shape, focusing degree and illumination distribution of the light of the lamp bead 31 are controlled, thereby meeting different lighting needs, such as focusing on a specific area or providing wide-angle lighting, and realizing the adjustable light output angle of the lamp without changing the appearance of the lamp; and by utilizing the rotation of the lens 21, the focusing and dispersion effects of the light beam can be optimized, thereby improving the lighting effect and optical performance, reducing light loss, and taking into account light efficiency, waterproof level and cost-effectiveness.

[0046] Reference Figure 2 and Figure 3The rotating member 4 includes a gear 41 and a tooth groove structure 42 provided on the lens plate 2. The tooth groove structure 42 is provided along the peripheral outer wall of the lens plate 2. The gear 41 is installed in the lamp panel body 1. The gear 41 is rotatably provided and meshes with the tooth groove structure 42.

[0047] The gear 41 is provided with a rotating shaft 7, which passes through the gear 41. The lamp panel body 1 is provided with a groove 12, in which the gear 41 and one end of the rotating shaft 7 are accommodated. The pressure plate 5 is provided with a through hole 51, in which the other end of the rotating shaft 7 is inserted. The rotating shaft 7 rotates within the through hole 51 and the groove 12. The design of the groove 12 and the through hole 51 enables the entire mechanical structure to provide precise rotation control, ensuring that the gear 41 and the rotating shaft 7 maintain a stable position and motion trajectory during operation. This design also enables the gear 41 and related components to operate stably for a long time, reduces the possibility of wear and failure caused by friction and motion instability, and improves the stability and durability of the entire rotating member 4.

[0048] A slot 71 is provided on the rotating shaft 7. In this embodiment, the slot 71 may be, but is not limited to, a straight slot. The slot 71 is connected to the through hole 51. The slot 71 is provided for the operator to use a tool to rotate the gear 41. In this embodiment, the operator can use an L-shaped wrench tool to insert into the slot 71 of the rotating shaft 7, rotate the rotating shaft 7, and thus rotate the gear 41 to drive the lens plate 2 to rotate. The design of the slot 71 allows the operator to easily use a tool to adjust the rotation of the gear 41 without directly contacting or affecting other components, thereby improving the accuracy and safety of the operation.

[0049] During actual use, the operator uses an L-shaped wrench tool, inserts the L-shaped wrench tool into the slot 71 through the through hole 51, and directly acts on the rotating shaft 7, thereby indirectly controlling the rotation of the gear 41. When the gear 41 rotates, its teeth engage with the tooth groove structure 42 on the lens plate 2, and the gear 41 will engage to drive the lens plate 2 to rotate, that is, the lens 21 will rotate, thereby changing the relative position relationship between the lens 21 and the lamp bead 31. The rotation of the lens 21 changes the refraction path and focusing mode of the light, thereby controlling the distribution shape, focus and illumination distribution of the light, thereby achieving the effect of changing the light-emitting angle; through the design of the gear 41 and the tooth groove structure 42, the light-emitting angle can be adjusted, thereby improving the functionality and practicality of the lamp, and providing users with a more flexible operating experience.

[0050] Reference Figure 4, the lens plate 2 and the lamp board 3 are provided with corresponding rotation limiting structures 8. In this embodiment, the rotation limiting structure 8 is provided at the center position of the lens plate 2 and the lamp board 3. The center position of the lens plate 2 is provided with a corresponding number of angle gears 9. In this embodiment, the angle gears 9 include angle gears 9 of 60°, 90°, and 115°. When the lens plate 2 rotates, the rotation limiting structures 8 on the lens plate 2 and the lamp board 3 form gear engagement at the 60°, 90°, and 115° gears. Through the design of the rotation limiting structure 8 and the angle gear 9, the operator can select and control the rotation angle of the lens plate 2 to ensure that the output of the light meets the requirements, and by limiting the rotation range of the lens plate 2, the lamp beads 31 are effectively protected from damage that may be caused by excessive rotation, thereby improving the functionality and operability of the lamp and ensuring the long-term stable operation of the lamp.

[0051] The lens plate 2 is further provided with an observation window 10 for observing the angle gear 9. The design of the observation window 10 improves the convenience and accuracy of operation. The operator can directly confirm the selected angle gear 9 through the observation window 10, thereby effectively managing and adjusting the optical characteristics of the lamp, thereby increasing the intuitiveness and controllability of the user's operation, making the adjustment of the lamp easier and more reliable.

[0052] Reference Figure 4 and Figure 5 In this embodiment, the initial assembly position of the lens plate 2 and the light board 3 is that the rotation limit structure 8 on the lens plate 2 and the light board 3 is at the 90° angle position 9; Figure 4 and Figure 6 When the position of the lens plate 2 needs to be adjusted, the operator uses an L-shaped wrench tool to insert into the slot 71 to control the rotation of the gear 41. The operator twists the L-shaped wrench tool clockwise, and the gear 41 rotates clockwise, engaging the transmission and driving the lens plate 2 to rotate counterclockwise. The lens plate 2 rotates 45° counterclockwise relative to the initial position. When the lens plate 2 cannot rotate, the observation window 10 turns to the left to display the angle gear 9 as 60°, which means that the angle of the lens 21 on the lens plate 2 is 60° at this time. Figure 4 and Figure 7 , the operator twists the L-shaped wrench tool counterclockwise, the gear 41 rotates counterclockwise, meshing the transmission and driving the lens plate 2 to rotate clockwise, the lens plate 2 rotates 45° clockwise relative to the initial position, when the lens plate 2 cannot rotate, the observation window 10 turns to the right to display the angle gear 9 as 115°, indicating that the angle of the lens 21 on the lens plate 2 is now 115°.

[0053] During actual use, when the lens plate 2 rotates, the lens plate 2 and the rotation limit structure 8 on the lamp board 3 will engage at the angle positions 9 of 60°, 90°, and 115°. This engagement ensures that the lens plate 2 can stay stably at each angle position 9 to prevent damage to the lamp beads 31 due to excessive rotation. During this process, the operator can directly select and control the rotation angle of the lens plate 2 through the observation window 10 to ensure that the light output meets the requirements.

[0054] The lamp also includes a sealing ring 6, which is arranged between the lens plate 2 and the lamp board 3. The pressure plate 5 presses on the lens plate 2 and forms pressure on the sealing ring 6. The sealing ring 6 forms an effective sealing design, which not only limits the entry of the external environment, but also protects internal components such as the lens plate 2 and the lamp board 3 from contamination or damage, thereby reducing maintenance and replacement costs, and can also improve the cleanliness and optical performance of the lens plate 2 and the lamp board 3.

[0055] A radiator 13 is also provided in the lamp panel main body 1. In the present embodiment, the radiator 13 includes but is not limited to a plurality of strip-shaped heat dissipating fins arranged in a circular array, and the plurality of heat dissipating fins are evenly distributed along the circumference of the lens plate 2 and the lamp plate 3. By designing the radiator 13 internally, the lamp can more effectively manage and disperse heat, thereby protecting the electronic components inside the lamp, such as the lamp beads 31, from overheating, extending the service life of the lamp, and improving the stability and performance of the lamp during operation.

[0056] In this embodiment, the lamp also includes a sensor 16, which is used to detect the surrounding environment or user operations and adjust the working mode or behavior of the lamp accordingly; specifically, in terms of the application of the lamp, the sensor 16 includes but is not limited to detecting signals such as human body, light, temperature, etc., to trigger the switch, brightness adjustment or other specific functions of the lamp; being equipped with the sensor 16 makes the lamp intelligent and automated, thereby improving the user's convenience and comfort. This design not only meets the requirements of modern energy conservation and environmental protection, but also increases the applicability and intelligent interactivity of the lamp in various application scenarios.

[0057] The implementation principle of a lamp according to an embodiment of the present application is as follows: in actual use, the initial assembly position of the lens plate 2 and the lamp plate 3 is that the rotation limit structure 8 on the lens plate 2 and the lamp plate 3 is at the 90° angle position 9, which means that the angle of the lens 21 on the lens plate 2 is 90° at this time;

[0058] When it is necessary to adjust the luminous angle of the lens 21, when it is necessary to adjust the luminous angle to a smaller value, the operator uses an L-shaped wrench tool, inserts the L-shaped wrench tool into the slot 71 through the through hole 51, and twists the L-shaped wrench tool clockwise to control the gear 41 to rotate counterclockwise. When the gear 41 rotates clockwise, its teeth engage with the tooth groove structure 42 on the lens plate 2, and the gear 41 engages to drive the lens plate 2 to rotate counterclockwise, that is, the lens 21 rotates, and the lens plate 2 rotates 45° counterclockwise relative to the initial position. When the lens plate 2 cannot rotate, the observation window 10 turns to the left to display the angle gear 9 as 60°, which means that the angle of the lens 21 on the lens plate 2 is 60° at this time.

[0059] When the luminous angle needs to be increased, the operator uses an L-shaped wrench tool to insert the L-shaped wrench tool into the slot 71 through the through hole 51. The operator twists the L-shaped wrench tool counterclockwise to control the gear 41 to rotate counterclockwise. The gear 41 rotates counterclockwise, meshing the transmission and driving the lens plate 2 to rotate clockwise. The lens plate 2 rotates 45° clockwise relative to the initial position. When the lens plate 2 cannot rotate, the observation window 10 turns to the right to display the angle gear 9 as 115°, indicating that the angle of the lens 21 on the lens plate 2 is now 115°.

[0060] The present application utilizes the rotation of the lens 21 to change the refraction path and focusing mode of the light, thereby controlling the distribution shape, focusing degree and illumination distribution of the light, so as to meet different lighting needs, such as focusing on a specific area or providing wide-angle lighting, and realizing the adjustable light output angle of the lamp without changing the appearance of the lamp; and by utilizing the rotation of the lens 21, the focusing and dispersion effects of the light beam can be optimized, thereby improving the lighting effect and optical performance, reducing light loss, and taking into account light efficiency, waterproof level and cost-effectiveness.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
