Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1-8This utility model provides an adjustable lighting range LED light-emitting module, including a substrate 1; multiple sets of LED beads 11 are fixedly connected to the center of the substrate 1; a fixing frame 12 is fixedly connected to the center of the substrate 1; a pair of rotating shafts 13 are rotatably connected to the inner side wall of the fixing frame 12; a shielding layer 14 is installed in the center of the rotating shaft 13; a lamp hole 16 is opened in the center of the shielding layer 14; a pair of fixing blocks 15 are fixedly connected to the side wall of the fixing frame 12; a micro stepper motor 17 is installed on the inner side wall of the fixing block 15. During operation, when the lighting is needed to create an atmosphere, the lighting needs to be adjusted according to the environment and requirements of the site to enhance the visual effect, highlight key points, and attract attention. The adjustable range LED light-emitting module allows operators to adjust the lighting range by driving the micro stepper motor 17 to rotate forward and backward via a remote control. The micro stepper motor 17 drives the rotating shaft 13 to rotate, which in turn moves the shielding layer 14 inside the mounting bracket 12. Initially, the lamp hole 16 and the LED bead 11 are aligned, and the light is unobstructed. When the micro stepper motor 17 drives the shielding layer 14 to rotate forward, the position of the lamp hole 16 shifts from the substrate 1. As needed, the shielding layer 14 will shield the LED bead 11, thereby controlling the lighting range of the LED bead 11 and achieving control over the brightness range, which facilitates the operator's adjustment of the light.

[0029] Furthermore, such as Figures 1-8 As shown, a pair of fixing plates 2 are detachably installed on the inner side wall of the fixing frame 12; a pair of first mounting grooves 21 are opened on the side wall of the fixing plate 2; an iron sheet 22 is fixedly connected to the inner side wall of the first mounting groove 21; multiple sets of second mounting grooves 23 are opened on the side wall of the fixing frame 12; a magnet 24 is fixedly connected to the inner side wall of the second mounting groove 23. During operation, the fixing plate 2 is installed inside the fixing frame 12 and located at the bottom of the shielding layer 14. The fixing plate 2 can fix the shielding layer 14 between the fixing frame 12 and the fixing plate 2, thereby improving the fixing effect of the equipment on the shielding layer 14 and providing a certain support effect for the shielding layer 14, thereby improving the sealing effect between the shielding layer 14 and the light-transmitting hole in the middle of the fixing frame 12 and reducing the light leakage caused by the gap between the fixing frame 12 and the lamp hole 16.

[0030] Furthermore, such as Figures 1-8As shown, the side wall of the mounting bracket 12 has multiple sets of heat dissipation holes 31; the middle of the substrate 1 has multiple sets of heat dissipation fins 3; the heat dissipation fins 3 are arranged in an array; the heat dissipation holes 31 are symmetrically arranged. During operation, a large amount of heat will be generated when the equipment runs for a long time. The heat dissipation fins 3 effectively increase the contact area between the equipment and the air, thereby improving the passive heat dissipation effect of the equipment and reducing the operating temperature of the equipment. In addition, the heat dissipation holes 31 can improve the airflow inside the mounting bracket 12, and a dustproof net is installed inside the heat dissipation holes 31, which can effectively reduce the entry of impurities and insects.

[0031] Furthermore, such as Figures 1-8 As shown, the decorative cover 4 is installed at the end of the fixed frame 12; the decorative cover 4 is detachably installed at the end of the fixed frame 12; the decorative cover 4 is made of transparent material. During operation, the decorative cover 4 installed at the end of the fixed frame 12 can cover various devices inside the fixed frame 12 to a certain extent, thereby effectively increasing the overall aesthetics of the devices and reducing the entry of impurities into the fixed frame 12.

[0032] Furthermore, such as Figures 1-8 As shown, a sponge pad 5 is provided at the end of the fixed plate 2. The sponge pad 5 is fixed to the end of the fixed plate 2. During operation, when the micro stepper motor 17 drives the shielding layer 14 to move, the sponge pad 5 can clean the surface of the shielding layer 14 to a certain extent. At the same time, the sponge pad 5 can protect the shielding layer 14 to a certain extent, reduce the hard friction between the shielding layer 14 and the fixed plate 2, thereby reducing the wear of the shielding layer 14 and improving the service life of the equipment.

[0033] Furthermore, such as Figures 1-8 As shown, the fixing frame 12 is provided with multiple sets of reflective rings 6 in the middle; the reflective rings 6 are fixed to the middle of the fixing frame 12; the position of the reflective rings 6 corresponds to the position of the LED beads 11. When working, the light is reflected out in the middle of the fixing frame 12 through the reflective rings 6, thereby improving the light diffusion effect, increasing the brightness of the equipment and improving the lighting effect of the equipment.

[0034] Working Principle: When lighting is needed to enhance the atmosphere, the lighting needs to be adjusted according to the environment and requirements to improve the visual effect, highlight key elements, and attract attention. Through the adjustable range of the LED light-emitting modules, staff can use a remote control to drive the micro stepper motor 17 to rotate forward and backward. The micro stepper motor 17 drives the rotating shaft 13 to rotate, which in turn moves the shielding layer 14 within the fixing frame 12. Initially, the lamp hole 16 and the LED beads 11 are aligned, and the light is unobstructed. When the micro stepper motor 17 drives the shielding layer 14 to rotate forward, the lamp hole... Position 16 is offset from substrate 1. As needed, the shielding layer 14 will shield the LED beads 11, thereby controlling the illumination range of the LED beads 11 and achieving control over the light range. This facilitates light adjustment by the operator. A fixing plate 2 is installed inside the fixing frame 12, located at the bottom of the shielding layer 14. The fixing plate 2 fixes the shielding layer 14 between the fixing frame 12 and the fixing plate 2, improving the device's fixation effect on the shielding layer 14 and providing some support. This improves the light transmission between the shielding layer 14 and the fixing frame 12. The sealing effect of the light hole reduces light leakage due to the gap between the mounting bracket 12 and the light hole 16. During prolonged operation, the equipment generates a significant amount of heat. The heat dissipation fins 3 effectively increase the contact area between the equipment and the air, thereby improving passive heat dissipation and reducing the operating temperature. Furthermore, the heat dissipation holes 31 improve airflow within the mounting bracket 12, and the dustproof mesh installed inside the holes effectively reduces the entry of impurities and insects. The decorative cover 4 at the end of the mounting bracket 12 provides some shielding for the various components inside. This effectively enhances the overall aesthetics of the equipment and reduces the entry of impurities into the mounting frame 12. When the micro stepper motor 17 moves the shielding layer 14, the sponge pad 5 can clean the surface of the shielding layer 14 and protect it, reducing hard friction between the shielding layer 14 and the mounting plate 2, thereby reducing wear and tear on the shielding layer 14 and extending the equipment's lifespan. The reflective ring 6 reflects light in the center of the mounting frame 12, improving light diffusion and increasing the equipment's brightness and illumination effect.
