[0016] 1. A Bluetooth receiver is installed inside the dining pendant lamp. The switch and color warmth of the full-spectrum LED can be directly controlled by the Bluetooth remote control. However, the hanging height of the full-spectrum LED is usually fixed, which makes it difficult for personnel to adjust the irradiation range of the full-spectrum LED according to their own needs. When the motor rotates forward, it can drive the first bevel gear to rotate. When the first bevel gear rotates, it can drive the second bevel gear to mesh and rotate. When the second bevel gear rotates, it can drive the rotating rod to rotate. When the rotating rod rotates, it can drive two sets of small gears to rotate. When the small gear rotates, it can drive the large gear to mesh and rotate. When the large gear rotates, it can drive the threaded rod to rotate. When the slider thread slides, it can slide through the limit block, and when the slider slides, it can drive the wire block to move;

[0017] While the rotating rod rotates, the wire reel can tighten the power cord. At the same time, the wire block can guide the power cord. While the power cord moves, the full-spectrum LED at the bottom of the lamp frame can be pulled. When the position of the full-spectrum LED rises to the specified position, the motor can be turned off. At this time, the irradiation range of the full-spectrum LED can be adjusted to a comfortable position. Conversely, when the motor reverses, the position of the full-spectrum LED will drop to the specified position. Through the plug-in installation of the acrylic pattern plate, different patterns can be replaced to express different information carriers, thereby facilitating maintenance and plug-in replacement. The acrylic pattern plate can be laser engraved with various texts and patterns according to actual conditions. By adjusting the position of the full-spectrum LED, the irradiation range of the full-spectrum LED is changed. At the same time, the brightness of the LED irradiation will also be improved accordingly, so that personnel can adjust the position of the full-spectrum LED according to their needs.

[0018] 2. The dining chandelier can be decorated through the acrylic pattern plate. Since the full-spectrum LED is easy to attract mosquitoes around during operation, it is easy to be polluted, and it will also affect people's dining. When the motor is running, the sound insulation cover can reduce the noise it generates. When the motor rotates, it can drive the connecting rod to rotate. When the connecting rod rotates, it can drive the disc to rotate. When the disc rotates, it can drive the guide block to rotate. When the disc rotates, it can drive the ribbon to swing. When the ribbon swings, it can drive away the mosquitoes at the bottom of the full-spectrum LED, thereby avoiding the gathering of mosquitoes at the bottom of the full-spectrum LED. The ribbon can prevent mosquitoes from contaminating the full-spectrum LED, avoid the dirt on the surface of the full-spectrum LED, and prevent mosquitoes from affecting people's dining.

[0019] 3. Since the dining pendant lamp is usually fixed to the indoor ceiling by expansion screws, personnel need to avoid installing the wiring harness during the installation of the dining pendant lamp, and the installation position of the wiring harness of the dining pendant lamp is usually fixed, resulting in a relatively fixed installation position of the dining pendant lamp. When the personnel cannot see the wiring harness inside the ceiling, the punching operation is easy to hit the installed wiring harness. When the block moves, it can drive the movable plate to move. When the movable plate moves, the spring can be stretched. When the spring is stretched to the specified position, the connection box can be pushed.

[0030] During specific implementation, a Bluetooth receiver 6 is installed inside the dining pendant lamp, and the switch and color warmth of the full-spectrum LED 5 can be directly controlled by the Bluetooth remote control 7. However, the hanging height of the full-spectrum LED 5 is usually fixed, which makes it difficult for personnel to adjust the irradiation range of the full-spectrum LED 5 according to their own needs. For this purpose, the motor 9 can be started. When the motor 9 rotates forward, it can drive the first bevel gear 10 to rotate. When the first bevel gear 10 rotates, it can drive the second bevel gear 14 to mesh and rotate. When the second bevel gear 14 rotates, it can drive the rotating rod 12 to rotate.

Through the plug-in installation of the acrylic pattern plate 4, different patterns can be replaced to express different information carriers, thereby facilitating maintenance and plug-in replacement, and the acrylic pattern plate 4 can be laser engraved and customized with various texts and patterns according to actual conditions.

[0032] See also Figure 1 , Figure 2 and Figure 7 It can be seen that by adjusting the position of the full-spectrum LED 5, the irradiation range of the full-spectrum LED 5 can be changed, and the brightness of the LED irradiation will also be improved accordingly, so that personnel can adjust the position of the full-spectrum LED 5 according to their own needs.

[0033] See also Figure 1 , Figure 3 and Figure 4 It can be seen that two groups of wire reels 13 are symmetrically arranged about the center of the connecting box 1, and connecting blocks 22 are installed on the front and back of the lamp frame 3. A guide groove 23 is opened at the bottom of the connecting block 22, and a sound insulation cover 24 is installed on the surface of the connecting block 22. A motor 25 is installed inside the sound insulation cover 24. A connecting rod 26 is connected between the motor 25 and the connecting block 22 through a bearing, and a disc 27 is connected to the end of the connecting rod 26. A guide block 28 is connected to the surface of the disc 27, and a ribbon 29 is connected to the bottom of the disc 27. A sliding structure is formed between the guide block 28 and the connecting block 22 through the guide groove 23, and the shape of the guide groove 23 is circular.

[0034] In specific implementation, the dining chandelier can play a decorative role through the acrylic pattern plate 4. Since the full-spectrum LED 5 is easy to attract mosquitoes around during operation, the full-spectrum LED 5 is easily contaminated, and it will also affect people's dining. For this reason, the motor 25 can be started. When the motor 25 is running, the sound insulation cover 24 can reduce the noise it generates. When the motor 25 rotates, it can drive the connecting rod 26 to rotate. When the connecting rod 26 rotates, it can drive the disc 27 to rotate. When the disc 27 rotates, it can drive the guide block 28 to rotate. When the guide block 28 rotates, it can rotate and slide through the guide groove 23. When the disc 27 rotates, it can drive the ribbon 29 to swing. When the ribbon 29 swings, it can drive away the mosquitoes at the bottom of the full-spectrum LED 5, thereby avoiding the gathering of mosquitoes at the bottom of the full-spectrum LED 5.

[0035] See also Figure 1 , Figure 3 and Figure 4 It can be seen that the streamer 29 can prevent mosquitoes from contaminating the full-spectrum LED 5, avoid the surface of the full-spectrum LED 5 from being dirty, and at the same time prevent mosquitoes from affecting people's dining.

[0036] See also Figure 1 , Figure 5 and Figure 6 It can be seen that docking blocks 30 are installed on both sides of the connection box 1, a mounting seat 31 is arranged on the top of the connection box 1, a knob 32 is threadedly connected to the bottom of the mounting seat 31, a mounting block 33 is movably connected inside the mounting seat 31, a fixing groove 34 is provided inside the mounting block 33, a spring 35 is connected inside the mounting seat 31, a movable plate 36 is connected to one end of the spring 35, a stopper 37 is connected to the end of the movable plate 36, the fixing grooves 34 are evenly spaced inside the mounting block 33, a sliding structure is formed between the docking block 30 and the mounting seat 31, and a sliding structure is formed between the mounting block 33 and the mounting seat 31.

[0037] During specific implementation, since the dining pendant lamp is usually fixed to the indoor ceiling by expansion screws, and since there is an installed wiring harness on the indoor ceiling, the personnel cannot observe its direction from the surface. In the process of installing the dining pendant lamp, the personnel need to avoid installing the wiring harness, and the installation position of the wiring harness of the dining pendant lamp is usually fixed, resulting in a relatively fixed installation position of the dining pendant lamp. When the personnel cannot see the wiring harness inside the ceiling, the installed wiring harness is easy to be hit during the punching operation. For this reason, the two sets of blocks 37 can be pulled away from each other. When the block 37 moves, the movable plate 36 can be driven to move. When the movable plate 36 moves, the spring 35 can be stretched. When the spring 35 is stretched to the specified position, the connection box 1 can be pushed, and the connection box 1 When moving, the docking block 30 can be driven to move. When the docking block 30 slides into the inside of the mounting seat 31, the two sets of blocks 37 can be loosened. At this time, the blocks 37 can be reset by the spring 35, so that the connection box 1 can be installed inside the mounting seat 31. At this time, the mounting block 33 can be pulled.

When the knob 32 is turned, the mounting block 33 can be limited and fixed by the fixing groove 34. At this time, the installation position of the connection box 1 can be adjusted, thereby greatly preventing the wiring harness installed on the indoor ceiling from being drilled by the puncher, reducing the risk of wiring harness damage.

[0038] See also Figure 1 , Figure 5 and Figure 6 It can be seen that by adjusting the installation position of the installation block 33, the connection box 1 can be installed more safely, and the installation position can be adjusted according to actual conditions.

[0039] To sum up, when using the full-spectrum eye-protection dining chandelier, the buttons on the Bluetooth remote control 7 can be used to enable the Bluetooth receiver 6 to receive control instructions, and the illumination brightness of the full-spectrum LED 5 can be adjusted to the corresponding brightness. At the same time, the color temperature of the full-spectrum LED 5 will also be changed accordingly according to the buttons on the Bluetooth remote control 7. The full-spectrum LED 5 can reduce the intensity of blue light, and the color rendering index of the full-spectrum LED 5 is high, and the light output is stable, which can play an eye protection effect. When the position of the full-spectrum LED 5 rises to the specified position, the motor 9 can be turned off. At this time, the illumination range of the full-spectrum LED 5 can be adjusted to a comfortable position. Conversely, when the motor 9 reverses, the position of the full-spectrum LED 5 will drop to the specified position. Through the plug-in installation of the acrylic pattern plate 4, different patterns can be replaced to express different information carriers, thereby facilitating maintenance and plug-in replacement, and the acrylic pattern plate 4 can be laser engraved and customized with various texts and patterns according to actual conditions. By adjusting the full spectrum The position of LED5 is adjusted, thereby changing the irradiation range of the full-spectrum LED5, and the brightness of the LED irradiation will also be improved accordingly, so that personnel can adjust the position of the full-spectrum LED5 according to their own needs. When the ribbon 29 swings, the mosquitoes at the bottom of the full-spectrum LED5 can be driven away, thereby avoiding the gathering of mosquitoes at the bottom of the full-spectrum LED5. The ribbon 29 can prevent mosquitoes from contaminating the full-spectrum LED5, avoid the surface of the full-spectrum LED5 from being dirty, and prevent mosquitoes from affecting people's meals. When the knob 32 is rotated, the mounting block 33 can be limited and fixed by the fixing groove 34. At this time, the installation position of the connection box 1 can be adjusted, thereby greatly avoiding the wiring harness installed on the indoor ceiling from being drilled by the puncher, reducing the risk of damage to the wiring harness, and by adjusting the installation position of the mounting block 33, the installation of the connection box 1 is safer, and the installation position can be adjusted according to actual conditions.
