Technical Field
[0001] This utility model relates to the field of circuit board and lighting technology, specifically to a central and surrounding multi-light source integrated circuit board structure. Background Technology
[0002] In recent years, the global incidence of myopia has been rising rapidly, especially among adolescents, becoming a major public health issue affecting public eye health. Research indicates that the lighting environment is a key factor influencing the development of myopia. Appropriate light intensity, uniformity, and dynamic characteristics can effectively regulate the eyeball's growth rhythm and slow excessive axial elongation, thus playing a role in myopia prevention and control. However, existing myopia prevention lighting equipment has significant shortcomings in terms of light source design and structural rationality. The light source layout is simple, mostly using direct light sources or simple array light sources in a single direction, making it difficult to meet the dual needs of large-area uniform illumination and localized precise illumination. It cannot simulate the three-dimensional distribution characteristics of natural light. The flexibility of light parameter adjustment is poor. The light source position of most devices is fixed, making it impossible to adjust it precisely according to the usage scenario and individual needs, making it difficult to realize personalized light intervention solutions. The circuit connection structure is unreasonable, and problems such as wire pulling and wear are prone to occur during equipment adjustment, affecting the stability and service life of the equipment. At the same time, poor circuit contact may cause fluctuations in light parameters, reducing the control effect. The integration of light source control is low. The lighting module and the adjustment drive module often adopt a separate circuit design, resulting in a large equipment size and complicated operation, which is not conducive to convenient use in home, school and other scenarios. Furthermore, traditional devices have limitations in controlling the dynamic characteristics of illumination, making it difficult to achieve special illumination modes such as forward and backward movement and strobe. However, recent research shows that dynamic light stimulation of visual targets at specific frequencies may have a unique effect on myopia prevention and control. In view of this, we propose a central and surrounding multi-source integrated circuit board structure to solve the existing problems. Utility Model Content
[0003] The purpose of this invention is to provide a central and surrounding multi-light source integrated circuit board structure to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a center and surrounding multi-light source integrated circuit board structure, including a mounting frame, a drive motor, a guide rod, a threaded rod, an adjusting block, a top plate, a flexible circuit strip, a lamp holder, an adjusting frame, an integrated board, a ring light source, a center light source, and a housing. The mounting frame is symmetrically arranged inside the housing, and an eye rest is provided on one side of the housing. The drive motor is installed inside the mounting frame. A guide rod is arranged in a ring on one side of the mounting frame. The top plate is fixedly connected to the side of the guide rod away from the mounting frame. A threaded rod is fixedly connected to the output end of the drive motor. One end of the threaded rod is located on the top plate. An adjusting block is movably connected to the threaded rod and the guide rod. The adjusting block has a threaded structure, and the adjusting block and the threaded rod cooperate with each other.
[0005] Preferably, an adjustment frame is fixedly connected to the side of the adjustment block away from the mounting frame, and a lamp holder is fixedly connected to the side of the adjustment frame away from the adjustment block. A ball bearing is arranged in a ring on one side of the lamp holder, and the lamp holder cooperates with the surface of the housing through the ball bearing.
[0006] Preferably, an integrated plate is provided below the lamp holder, and an annular light source is arranged in a ring along the annular edge of the upper surface of the lamp holder. The annular light source is composed of LED beads and strobe lights evenly arranged along the circumference of the lamp holder, and the annular light source is electrically connected to the integrated plate through wires. A central light source is fixedly provided in the middle of the lamp holder. The central light source is composed of two types of LED beads, namely three red LED beads and one white LED bead, and is individually controlled. Its central axis coincides with the central axis of the lamp holder, and the central light source is electrically connected to the integrated plate through wires.
[0007] Preferably, a flexible circuit strip is provided on one side of the drive motor. The flexible circuit strip is a bendable flexible printed circuit. One end of the circuit strip is electrically connected to the control terminal of the drive motor, and the other end passes around the outside of the guide rod and extends to the edge of the integrated board, where it is electrically connected to the control circuit of the integrated board.
[0008] Preferably, at least three guide rods are provided, and they are distributed at equal angles along the circumference of the mounting frame; the outer wall of the guide rod is provided with a smooth and wear-resistant coating, and the coating material is polytetrafluoroethylene.
[0009] Preferably, a controller is provided on the upper side of the housing, and the controller is electrically connected to the drive motor and the integrated board.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. When the drive motor receives the control signal, its output end drives the threaded rod to rotate. Since the adjusting block has a threaded structure inside and is threadedly engaged with the threaded rod, the rotational motion of the threaded rod is converted into the linear motion of the adjusting block. The guide rod guides and limits the movement of the adjusting block. The adjusting block can slide up and down along the axis of the guide rod to ensure that the adjusting block drives the lamp holder to rise and fall stably and avoid deviation. The polytetrafluoroethylene coating on the outer wall of the guide rod can reduce the frictional resistance between the adjusting block and the guide rod, reduce mechanical wear, extend the service life of the structure, and make the lifting and lowering movement smoother. 2. The ring light source consists of 3 yellow LEDs and 3 green LEDs evenly arranged along the ring edge of the lamp holder. When powered on, they flash simultaneously at a certain frequency. The diffuser in the middle emits light from the 3 red LEDs or 1 white LED at the bottom, forming a circular and uniform light source. The light coverage is wide and uniform, and the light emission center axis coincides with the center axis of the lamp holder. When powered on, the light is focused and output along the axis, resulting in high light intensity and strong directionality. 3. External control signals are first transmitted to the integrated board. As the core of the circuit board, the integrated board outputs drive current to the ring light source and the central light source through wires to control the switching and brightness of the light source. On the other hand, it transmits motor control signals to the drive motor through a flexible circuit strip. One end of the flexible circuit strip is connected to the integrated board, and the other end goes around the guide rod to connect to the drive motor. When the adjusting block moves up and down along the guide rod, the flexible circuit strip can deform synchronously with the adjusting block to avoid the line being pulled and broken, and to ensure that the circuit continues to conduct.

The mounting frame 1 is symmetrically arranged inside the housing 14, and an eye support 16 is provided on one side of the housing 14. The drive motor 2 is arranged inside the mounting frame 1, and a guide rod 3 is arranged in a ring on one side of the mounting frame 1. The top plate 6 is fixedly connected to the side of the guide rod 3 away from the mounting frame 1. The output end of the drive motor 2 is fixedly connected to the threaded rod 4, and one end of the threaded rod 4 is located on the top plate 6. An adjusting block 5 is movably connected to the threaded rod 4 and the guide rod 3. The adjusting block 5 has a threaded structure, and the adjusting block 5 and the threaded rod 4 cooperate with each other. When the drive motor 2 receives the control signal, its output end drives the threaded rod 4 to rotate. Since the adjusting block 5 has a threaded structure inside and is threadedly engaged with the threaded rod 4, the rotational motion of the threaded rod 4 is converted into the linear motion of the adjusting block 5. The guide rod 3 guides and limits the movement of the adjusting block 5. The adjusting block 5 can slide up and down along the axis of the guide rod 3 to ensure that the adjusting block 5 drives the lamp holder 8 to rise and fall stably and avoid deviation. The polytetrafluoroethylene coating on the outer wall of the guide rod 3 can reduce the frictional resistance between the adjusting block 5 and the guide rod 3, reduce mechanical wear, extend the service life of the structure, and make the lifting motion smoother.
[0015] In an optional embodiment, an adjustment frame 9 is fixedly connected to the side of the adjustment block 5 away from the mounting frame 1, and a lamp holder 8 is fixedly connected to the side of the adjustment frame 9 away from the adjustment block 5.

[0016] In an optional embodiment, an integrated plate 10 is disposed below the lamp holder 8, and an annular light source 11 is disposed on the upper surface of the lamp holder 8 along its annular edge. The annular light source 11 is composed of 3 yellow LED beads and 3 green LED beads evenly arranged along the circumference of the lamp holder 8, and the annular light source 11 is electrically connected to the integrated plate 10 through wires.

The central light source 12 is composed of 3 red LED beads and 1 white LED bead, and its central axis coincides with the central axis of the lamp holder 8. The central light source 12 is electrically connected to the integrated plate 10 through wires. The ring light source 11 is composed of 3 yellow LED beads and 3 green LED beads evenly arranged along the ring edge of the lamp holder 8. After being powered on, it forms a ring surface light source with a wide and uniform illumination coverage. The central light source 12 is a focused illumination source consisting of 3 red LED beads and 1 white LED bead. Its central axis coincides with the central axis of the lamp holder 8. After being powered on, the light is focused and output along the axis direction, resulting in high light intensity and strong directionality. The integrated board 10 can independently control the working status of the ring light source and the central light source to adapt to the lighting needs of different scenarios.
[0017] In an optional embodiment, a flexible circuit strip 7 is provided on one side of the drive motor 2. The flexible circuit strip 7 is a bendable flexible printed circuit. One end of it is electrically connected to the control terminal of the drive motor 2, and the other end passes around the outside of the guide rod 3 and extends to the edge of the integrated board 10, where it is electrically connected to the control circuit of the integrated board 10. The external control signal is first transmitted to the integrated board 10. As the core of the circuit board, the integrated board 10 outputs driving current to the ring light source 11 and the central light source 12 through wires to control the switching and brightness of the light source. On the other hand, it transmits the motor control signal to the drive motor 2 through the flexible circuit strip 7. One end of the flexible circuit strip 7 is connected to the integrated board 10, and the other end passes around the guide rod 3 and connects to the drive motor 2.

[0019] The working principle of this utility model is as follows: When the drive motor 2 receives the control signal, its output end drives the threaded rod 4 to rotate. Since the adjusting block 5 has a threaded structure inside and is threadedly engaged with the threaded rod 4, the rotational motion of the threaded rod 4 is converted into the linear motion of the adjusting block 5. The guide rod 3 guides and limits the movement of the adjusting block 5. The adjusting block 5 can slide up and down along the axis of the guide rod 3 to ensure that the adjusting block 5 drives the lamp holder 8 to rise and fall stably and avoid deviation. The polytetrafluoroethylene coating on the outer wall of the guide rod 3 can reduce the frictional resistance between the adjusting block 5 and the guide rod 3, reduce mechanical wear, extend the service life of the structure, and make the lifting motion smoother. The ring light source 11 is composed of 3 yellow LED beads and 3 green LED beads evenly arranged along the ring edge of the lamp holder 8. After being powered on, it forms a ring surface light source with a wide and uniform illumination coverage. The central light source 12 is a focused illumination source consisting of 3 red LED beads and 1 white LED bead. Its central axis coincides with the central axis of the lamp holder 8. After being powered on, the light is focused and output along the axial direction, resulting in high light intensity and strong directionality. The external control signal is first transmitted to the integrated board 10. As the core of the circuit board, the integrated board 10 outputs driving current to the ring light source 11 and the central light source 12 through wires to control the switching and brightness of the light source. On the other hand, it transmits the motor control signal to the drive motor 2 through the flexible circuit strip 7. One end of the flexible circuit strip 7 is connected to the integrated board 10, and the other end passes around the guide rod 3 and connects to the drive motor 2. When the adjusting block 5 moves up and down along the guide rod 3, the flexible circuit strip 7 can deform synchronously with the adjusting block 5 to avoid the line being pulled and broken, and to ensure the continuous conduction of the circuit.
