[0002] LEDs (light-emitting diodes), as solid-state semiconductor devices, have an electroluminescent semiconductor material as their core structure. This material is fixed by a lead frame and encapsulated in epoxy resin to protect the internal wires. With significant advantages such as low power consumption, long lifespan, and high environmental friendliness, LEDs have gradually replaced traditional fluorescent lamps and become the mainstream lighting device.

[0003] However, in practical applications, the lighting requirements of LED lighting modules vary significantly across different scenarios: for example, residential walkways require soft, wide-area lighting, urban main roads require high-intensity directional lighting, and park landscape areas need dynamically adjusted lighting coverage. Existing LED lighting devices (especially streetlights) largely rely on fixed optical designs for their lighting range, only allowing limited changes in lighting effects through adjusting luminous intensity, and cannot flexibly adapt the lighting range to different scenarios. This structural limitation results in insufficient adaptability when applied across various scenarios, making it difficult to meet diverse lighting needs. Therefore, there is an urgent need to develop a semiconductor lighting module with easily adjustable lighting range. Utility Model Content

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 that facilitates adjustment of the illumination range includes a lampshade 1. Slide grooves are provided on the front and rear sides of the inner wall of the lampshade 1, and sliders are slidably connected inside the slide grooves.

An LED light-emitting module 3 is fixedly connected to the bottom of the movable plate 2 via a bracket. Slide grooves are provided on both the front and rear sides of the bottom of the movable plate 2. Light guide plates 4 are hinged to the front and rear sides inside the lampshade 1, and sliding blocks 5 are slidably connected inside the slide grooves. The top of the light guide plate 4 is hinged to the bottom of the sliding block 5. The slider slides up and down inside the slide groove, and the sliding block 5 slides back and forth inside the slide groove. A drive block 7 slides up and down inside the opening 6. The lampshade 1, light guide plate 4, and LED light-emitting module 3 are all existing common technologies and are common knowledge to those skilled in the art. Therefore, this application will not elaborate further. All related content not disclosed in this application is common knowledge to those skilled in the art, and this application will not elaborate further.

[0021] refer to Figure 2 The lampshade 1 has an opening 6 on the right side. A drive block 7 is slidably connected inside the opening 6. The drive block 7 is fixedly connected to the movable plate 2. A threaded rod 8 is rotatably connected inside the opening 6. The threaded rod 8 is threadedly connected to the drive block 7. A motor 9 is fixedly connected to the top of the lampshade 1. The output end of the motor 9 is fixedly connected to the threaded rod 8.

[0022] As a technical optimization of this utility model, the motor 9 drives the threaded rod 8 to rotate, which in turn moves the drive block 7 within the opening 6, thereby achieving automated adjustment of the movable plate 2. This electric adjustment method eliminates the need for manual operation, saving manpower and allowing for precise control of the moving distance of the movable plate 2, ensuring the accuracy of the lighting range adjustment. Simultaneously, the cooperation between the motor 9 and the threaded rod 8 ensures a smooth and orderly adjustment process, avoiding deviations that may occur with manual adjustment. This allows users to quickly switch the desired lighting range with simple control, improving ease of use and adjustment efficiency.

[0023] refer to Figure 4 The lampshade 1 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the lampshade 1, while the inner ring of the bearing is fixedly connected to the threaded rod 8.

[0024] As a technical optimization of this utility model, the bearing effectively reduces the friction between the threaded rod 8 and the lampshade 1 during rotation, making the rotation of the threaded rod 8 smoother and more stable, reducing component wear, and extending the service life of the device. The bearing's fixing effect on the threaded rod 8 prevents it from shaking or shifting during rotation, ensuring the accuracy of the drive block 7 in moving the movable plate 2, thereby ensuring the stability of the light guide plate 4 angle adjustment, making the light range adjustment more reliable, and reducing the deviation in lighting effect caused by structural instability.

[0025] refer to Figure 1 A protective frame 10 is fixedly connected to the right side of the lampshade 1, and the protective frame 10 is located on the right side of the opening 6.

[0026] As a technical optimization of this utility model, the protective frame 10, located on the right side of the opening 6, can effectively prevent external debris from entering the interior of the opening 6, avoiding its adhesion to components such as the threaded rod 8 and the drive block 7 and affecting normal operation. Simultaneously, the protective frame 10 prevents external forces from colliding with the structure inside the opening 6, effectively protecting the internal drive components, reducing the probability of component damage, decreasing maintenance frequency and costs, improving the durability and reliability of the device in complex environments, and ensuring long-term stable operation.

[0027] refer to Figure 1 The top of the lampshade 1 is fixedly connected to the four sides of the mounting bracket 11, and the surface of the mounting bracket 11 is provided with mounting openings 12.

[0028] As a technical optimization of this utility model, the design of the mounting bracket 11 and the mounting port 12 provides a convenient way to fix the lampshade 1, making it adaptable to various installation scenarios. The distribution of the mounting bracket 11 and the setting of the mounting port 12 make it convenient for users to choose the appropriate installation position and method according to actual needs. Whether fixed to the ceiling or other supporting structures, installation and disassembly can be completed quickly, simplifying the installation process, saving installation time and labor costs, and improving the versatility and practicality of the device.

[0029] refer to Figure 2 The inner wall of the lampshade 1 and the side of the light guide plate 4 near the LED light-emitting module 3 are both provided with reflective coatings.

[0030] As a technical optimization of this utility model, the reflective coating allows the light emitted by the LED light-emitting module 3 to be reflected multiple times, reducing light loss on the inner wall of the lampshade 1 and the light guide plate 4, thus improving light utilization. The reflective coating enhances the focusing and reflection effect of light, enabling more light to be effectively projected onto the desired lighting area, improving brightness and uniformity, achieving better lighting effects with the same energy consumption, meeting energy-saving requirements, and enhancing the practicality and comfort of the lighting.

[0031] The working principle and usage process of this utility model are as follows: In use, the core of adjusting the illumination range of this semiconductor lighting module lies in the flexible change of the angle of the light guide plate 4 through the linkage of the mechanical structure. When the illumination range needs to be adjusted, the motor 9 starts, driving the threaded rod 8 to rotate. The threaded engagement between the threaded rod 8 and the drive block 7 causes the drive block 7 to move linearly along the opening 6. The movement of the drive block 7 directly drives the movable plate 2 to move synchronously. The two sides of the movable plate 2 are slidably connected to the sliding grooves on the inner wall of the lampshade 1 via sliders. The limiting effect of the sliding grooves on the sliders ensures that the movable plate 2 remains stable during movement, avoiding any impact on adjustment accuracy due to shaking. The sliding groove at the bottom of the movable plate 2 moves synchronously with the movable plate 2. The sliding block 5 inside the sliding groove is hinged to the top of the light guide plate 4. When the movable plate 2 moves, the sliding block 5 slides relative to the sliding groove, thereby generating a pushing or pulling force on the light guide plate 4. Because the light guide plate 4 is hinged to the inner wall of the lampshade 1, under the force of the sliding block 5, the light guide plate 4 rotates around the hinge point, thereby changing the angle between itself and the LED light-emitting module 3.

[0032] The light emitted by the LED light-emitting module 3 shines onto the light guide plate 4. The change in the angle of the light guide plate 4 changes the direction of light reflection and refraction: when the light guide plate 4 rotates outward, the light is guided to a wider area, thus expanding the illumination range, which is suitable for scenarios such as community walkways that require wide-area lighting; when the light guide plate 4 rotates inward, the light is concentrated and reflected, forming a more directional beam, which meets the needs of strong directional lighting for urban main roads, etc.

[0033] For example, the downward movement of the drive block 7 causes the movable plate 2 to move downward, which in turn causes the LED light-emitting module 3 to move downward, reducing the distance between the bottom of the LED light-emitting module 3 and the bottom of the lampshade 1. By utilizing the principle of light propagation, the illumination range increases. At the same time, the downward movement of the movable plate 2 causes the sliding blocks 5 on the front and rear sides to move closer to each other, causing the light guide plate 4 to rotate outward, further increasing the illumination range. This makes the device suitable for scenarios requiring wide-area lighting, such as community walkways.
