Description

Technical Field

[0001] This utility model relates to the field of semiconductor lighting module technology, specifically a semiconductor lighting module with a wide illumination angle. Background Technology

[0002] Solid-state semiconductor white light-emitting diodes (LEDs), as the fourth generation of green lighting sources, have gradually replaced traditional incandescent lamps and fluorescent lamps, becoming a core technology solution in the field of modern lighting and decoration, thanks to their significant advantages such as energy saving, environmental protection, excellent impact resistance, and long service life.

[0003] However, current mainstream semiconductor lighting modules still suffer from structural defects: their semiconductor light-emitting elements are mostly fixed on the surface of a planar substrate. Due to the structural design of the planar substrate, their illumination range is naturally limited, and the illumination angle is generally narrow and fixed. At the same time, existing modules lack a flexible angle adjustment mechanism and cannot be adapted to the needs of actual application scenarios, which seriously restricts the application expansion of semiconductor lighting modules in diversified scenarios. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a semiconductor lighting module with a wide illumination angle, which has the advantages of a wide illumination angle and easy adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a semiconductor lighting module with a wide illumination angle, comprising a mounting cylinder, wherein a support frame is fixedly connected to the top and bottom of the mounting cylinder, a threaded rod is rotatably connected to the inside of the support frame, the top of the threaded rod extends to the top of the support frame and is fixedly connected to a first bevel gear, a second bevel gear is rotatably connected to the inside of the mounting cylinder, the first bevel gear meshes with the second bevel gear, a motor is fixedly connected to the surface of the mounting cylinder, the output end of the motor is fixedly connected to the second bevel gear, two sliding grooves are provided on the inner wall of the mounting cylinder, the two sliding grooves are symmetrically arranged, and a movable frame is slidably connected inside the sliding groove, the movable frame is threadedly connected to the threaded rod, a support plate is fixedly connected to the bottom of the movable frame through a support rod, an LED light-emitting module is fixedly connected to the bottom of the support plate, and a concave lens is provided below the mounting cylinder.

[0008] As a preferred embodiment of this utility model, a maintenance cover plate is provided on the top of the mounting cylinder, and a bolt is provided on the top of the maintenance cover plate. The bolts are arranged in a ring and evenly distributed on the top of the maintenance cover plate. The bottom of the bolts penetrates the maintenance cover plate and is threadedly connected to the mounting cylinder.

[0009] As a preferred embodiment of this utility model, the support frame is internally fixedly connected to a bearing, with the outer ring of the bearing fixedly connected to the support frame and the inner ring of the bearing fixedly connected to the threaded rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a motor to drive the second bevel gear to rotate, which in turn drives the meshing first bevel gear and threaded rod to rotate, causing the movable frame to move up and down along the slide groove, thereby adjusting the position of the LED light-emitting module.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, a semiconductor lighting module with a wide illumination angle includes a mounting cylinder 1. Support frames 2 are fixedly connected to the top and bottom of the mounting cylinder 1. A threaded rod 3 is rotatably connected inside the support frame 2. The top of the threaded rod 3 extends above the support frame 2 and is fixedly connected to a first bevel gear 4. A second bevel gear 5 is rotatably connected inside the mounting cylinder 1, and the first bevel gear 4 meshes with the second bevel gear 5. A motor 6 is fixedly connected to the surface of the mounting cylinder 1, and the output end of the motor 6 is fixedly connected to the second bevel gear 5. A threaded groove is provided on the surface of the threaded rod 3 in the area between the upper and lower support frames 2. Two sliding grooves are provided on the inner wall of the mounting cylinder 1, and the two sliding grooves are symmetrically arranged. A movable frame 7 is slidably connected inside the sliding groove. The movable frame 7 is threadedly connected to the threaded rod 3. A support plate 8 is fixedly connected to the bottom of the movable frame 7 via a support rod. An LED light-emitting module 9 is fixedly connected to the bottom of the disk 8. A concave lens 10 is provided below the mounting cylinder 1. The movable frame 7 slides up and down in the slide groove. When the LED light-emitting module 9 moves down to the lowest position, it is also above the focal point of the concave lens 10. This setting allows the LED light-emitting module 9 to gradually approach the focal point above the concave lens 10 as it moves down. By utilizing the light-diverging principle of the concave lens 10, the illumination range is increased. At the same time, the operator can rotate and disassemble the fixed cylinder 11 to replace the fixed cylinder 11 with concave lenses 10 of different focal lengths, thereby adjusting the illumination angle of the device. The LED light-emitting module 9, motor 6, and mounting cylinder 1 are all existing common technologies and are common knowledge to those skilled in the art. This application will not elaborate on them in detail. The relevant contents not disclosed in this application are all common knowledge to those skilled in the art and will not be elaborated on them in detail.

[0021] refer to Figure 1 The mounting cylinder 1 has a threaded connection to a fixing cylinder 11, and the concave lens 10 is fixedly connected to the inner wall of the fixing cylinder 11.

[0022] As a technical optimization of this utility model, the mounting cylinder 1 and the fixing cylinder 11 are connected by a thread, allowing the fixing cylinder 11 to be easily disassembled and replaced. Since the concave lens 10 is fixed to the inner wall of the fixing cylinder 11, different fixing cylinders 11 can be used with concave lenses 10 of different parameters, thus flexibly adjusting the illumination angle of the device. This design allows the device to move beyond a single illumination range and quickly switch according to actual needs, enhancing the adaptability and versatility of the device. Simultaneously, the threaded connection is stable and reliable, ensuring that the fixing cylinder 11 is not easily loosened during use, guaranteeing the stability of the lighting effect.

[0023] refer to Figure 4 A sealing ring 12 is fixedly connected to the bottom of the mounting cylinder 1. The bottom of the sealing ring 12 is in contact with the fixing cylinder 11. Multiple anti-slip strips 13 are fixedly connected to the surface of the fixing cylinder 11 in a ring-shaped and uniformly distributed manner.

[0024] As a technical optimization of this utility model, the sealing ring 12 at the bottom of the mounting cylinder 1 is tightly fitted to the fixing cylinder 11, which effectively prevents dust, moisture and other impurities from entering the device, avoiding the impact of contamination on the performance or shortening of the life of internal components, and significantly improving the sealing performance and protection capability of the device. The anti-slip strip 13 on the surface of the fixing cylinder 11 increases the friction between the hand and the fixing cylinder 11, effectively preventing slippage when installing or removing the fixing cylinder 11, making the operation more labor-saving and convenient, improving the user experience, and also ensuring the safety of the assembly and disassembly process.

[0025] refer to Figure 1 The top of the mounting cylinder 1 is provided with a maintenance cover plate 14, and the top of the maintenance cover plate 14 is provided with bolts 15. There are several bolts 15, which are evenly distributed in a ring on the top of the maintenance cover plate 14. The bottom of the bolts 15 penetrates the maintenance cover plate 14 and is threadedly connected to the mounting cylinder 1.

[0026] As a technical optimization of this utility model, the maintenance cover 14 on the top of the mounting cylinder 1 provides a convenient passage for the maintenance and repair of the internal components of the device. When it is necessary to inspect, repair or replace parts of the internal structure, the maintenance cover 14 can be opened simply by removing the bolts 15, without disassembling the entire device, which greatly simplifies the maintenance process and saves time and labor costs. The fixing method of the bolts 15 ensures the stability of the connection between the maintenance cover 14 and the mounting cylinder 1, ensuring the normal operation of the device.

[0027] refer to Figure 2The support frame 2 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the support frame 2, while the inner ring of the bearing is fixedly connected to the threaded rod 3.

[0028] As a technical optimization of this utility model, the threaded rod 3 is connected to the support frame 2 via a bearing inside the support frame 2. This significantly reduces the frictional resistance between the threaded rod 3 and the support frame 2 during rotation, making the rotation of the threaded rod 3 smoother and more stable, and reducing wear and noise caused by friction. This not only extends the service life of the threaded rod 3 and the support frame 2, but also ensures the accuracy and stability of the LED light-emitting module 9 during adjustment, avoiding illumination angle deviations caused by jamming or shaking, and improving the reliability and durability of the device operation.

[0029] refer to Figure 1 A mounting bracket 16 is fixedly connected to the surface of the mounting cylinder 1. The surface of the mounting bracket 16 has mounting openings 17. There are several mounting openings 17, which are evenly distributed in a ring on the surface of the mounting bracket 16.

[0030] As a technical optimization of this utility model, the mounting bracket 16 on the surface of the mounting cylinder 1 provides a stable mounting foundation for the device, and the design of the mounting port 17 allows it to adapt to various installation methods and positions. Whether it needs to be fixed to a wall, ceiling, or other supporting structure, installation and fixation can be easily achieved through the mounting port 17, simplifying the installation process. This design enhances the installation flexibility of the device, enabling it to adapt to various usage scenarios and installation environments, and expanding the application range of the device.

[0031] The working principle and usage process of this utility model are as follows: First, ensure the device is securely installed and check the connection between the mounting bracket 16 and the mounting port 17 to ensure the mounting cylinder 1 is in a stable position. Then, connect the device to the power supply to prepare for adjusting the illumination angle. If it is necessary to change the illumination angle by adjusting the relative position of the LED light-emitting module 9 and the concave lens 10, the motor 6 can be started. The output end of the motor 6 drives the second bevel gear 5 to rotate. Because the first bevel gear 4 meshes with the second bevel gear 5, the rotation of the second bevel gear 5 will drive the first bevel gear 4 to rotate synchronously, thereby driving the threaded rod 3 to rotate smoothly under the action of the bearing inside the support frame 2. When the threaded rod 3 rotates, the movable frame 7, which is threadedly connected to the threaded rod 3, will be limited by the sliding groove and slide up and down along the sliding groove. The movable frame 7 drives the support plate 8 and the LED light-emitting module 9 at the bottom to move together through the support rod. When the LED light-emitting module 9 moves upward, the distance between it and the concave lens 10 increases. At this time, the light-diffusing effect of the concave lens 10 changes, and the illumination angle decreases accordingly. When the LED light-emitting module 9 moves downward, it gradually approaches the concave lens 10. The light-diffusing effect of the concave lens 10 is enhanced, and the illumination angle expands accordingly. During the adjustment process, it is necessary to observe the changes in the illumination range. After the desired angle is reached, the motor 6 is turned off, and the LED light-emitting module 9 is fixed in the current position.

[0032] Furthermore, if it is necessary to further adjust the illumination angle by replacing the concave lens 10 with one of different parameters, the anti-slip strips 13 on the surface of the fixing cylinder 11 can be used to hold the fixing cylinder 11 and rotate it. Since the fixing cylinder 11 and the mounting cylinder 1 are connected by threads, the fixing cylinder 11 will gradually detach from the mounting cylinder 1 during rotation. At this time, care should be taken to keep the concave lens 10 clean and avoid touching the lens surface. After removing the original fixing cylinder 11, select a new fixing cylinder 11 equipped with a suitable concave lens 10, align it with the threaded interface of the mounting cylinder 1, and rotate the fixing cylinder 11 with the help of the anti-slip strips 13 to make the fixing cylinder 11 and the mounting cylinder 1 tightly connected until the top of the fixing cylinder 11 and the sealing ring 12 at the bottom of the mounting cylinder 1 are completely in contact, ensuring a stable connection and good sealing. After the replacement is completed, start the motor 6 again and fine-tune the position of the LED light-emitting module 9 so that the relative position of the LED light-emitting module 9 and the new concave lens 10 reaches the optimal state to obtain the ideal illumination angle. If any abnormal operation of the device is found during the adjustment process, the maintenance cover 14 can be opened by removing the bolts 15 on it. The connections of the internal components can be checked, such as the threaded fit between the threaded rod 3 and the movable frame 7, and the meshing state of the first bevel gear 4 and the second bevel gear 5. After troubleshooting, the maintenance cover 14 can be reinstalled, ensuring that the bolts 15 are tightened. Finally, the power should be turned off, and all components of the device should be confirmed to be reset normally to complete the entire illumination angle adjustment process.
