Abstract
Description
Technical Field
[0001] This utility model relates to the field of light source conversion technology, and in particular to a printed light source conversion device. Background Technology
[0002] In the LCD industry, the backlight module plays a crucial role. Its overall light source is mainly provided by LED strips, which are actually composed of numerous LED particles and exhibit the characteristics of a linear light source. Normally, the position of the LED strip is basically fixed on one side of the backlight module. However, LCD displays require the backlight to achieve uniform light emission across the entire surface to ensure good visual effects and display quality. Therefore, there is an urgent need for a specialized device to efficiently and accurately convert linear light sources into surface light sources. Thus, a printed light source conversion device was designed.
[0003] In existing technologies, converting line light sources into surface light sources has the problem of poor light uniformity, which easily leads to areas that are too bright or too dark. This makes it difficult to achieve the ideal standard of brightness uniformity in the LCD screen, seriously affecting the visual effect and display quality. Furthermore, the installation and disassembly of the light-emitting board is inconvenient. During the installation, maintenance, and upgrade of the equipment, the inconvenience of installation and disassembly not only consumes a lot of manpower and time costs, but may also cause damage to the light board or other related components due to improper operation. Utility Model Content
[0004] This disclosure relates to a printed light source conversion device to solve the problems of poor light uniformity and inconvenient installation and removal of light-emitting panels in existing light source conversion devices.
[0005] In a first aspect, this disclosure provides a printed light source conversion device, specifically including: a motherboard;
[0006] The motherboard is an optical acrylic structure board. The lower surface of the motherboard is provided with dots, which are spherical in structure. The dots are arranged in a staggered rectangular array on the lower surface of the motherboard. The surface of the dots is printed with a reflective ink layer, the main material of which is PMMA reflective particles. The upper surface of the motherboard is provided with a convex arc-shaped structure that protrudes above the motherboard body. Light-emitting lamps are provided at both ends of the motherboard. Two sets of mounting bases are provided on both sides of the motherboard. Side plates are installed at the upper and lower ends of the mounting bases by bolts. A fixing base is fixed at the end of the mounting base closest to the motherboard. Two sets of suction cups are fixed on the fixing base and are attached to the back of the light-emitting lamps.
[0007] In at least some embodiments,
[0008] The mounting base is fixed with a first fixing plate and a second fixing plate. Two sets of rails are fixed between the first fixing plate and the second fixing plate. Movable plates slide on the two sets of rails, and threaded holes are provided on the movable plates.
[0009] In at least some embodiments,
[0010] A lead screw is installed between the No. 1 and No. 2 fixed plates via a bearing. The lead screw is threaded into a threaded hole on the movable plate, and a knob is installed on the lead screw via a bolt.
[0011] In at least some embodiments,
[0012] Both sets of side plates are hinged with hinge plates, and a clamping plate is fixed on the side of the hinge plate closest to the main board. Anti-slip protrusions are fixed on the clamping plate.
[0013] In at least some embodiments,
[0014] A round rod is fixed on the side of the side plate away from the main board. A first connecting block slides on the round rod, and a second connecting block is hinged to the first connecting block.
[0015] In at least some embodiments,
[0016] The No. 2 connecting block and the movable plate are connected by a No. 1 connecting plate via a pin shaft, and the No. 2 connecting block and the No. 2 fixed plate are connected by a No. 2 connecting plate.
[0017] In at least some embodiments,
[0018] Four base plates are provided below the main board. Cylinder seats are installed on the base plates by bolts. The upper end of the cylinder seat is provided with a through hole. A movable plate is movable inside the cylinder seat. Conical springs are installed at the upper and lower ends of the movable plate. A connecting rod is installed at the upper end of the movable plate by bolts. The upper end of the connecting rod is fixedly connected to the lower end of the main board.
[0019] This utility model provides a printed light source conversion device, which has the following beneficial effects:
[0020] The motherboard in this invention is an acrylic structural board. The lower surface of the motherboard has a dotted surface with spherical dots arranged in a staggered rectangular array. A reflective ink layer is printed on the surface of the dots, the main material of which is PMMA reflective particles. Acrylic has excellent optical properties, providing a stable foundation for light transmission as the motherboard material. The spherical dotted surface design, combined with its high light transmittance, effectively refracts light from the light-emitting panel. Distributing the dots in a staggered rectangular array on the lower surface of the motherboard cleverly avoids the problem of uneven light concentration or dispersion, allowing light to diffuse evenly in all directions. This forms a uniformly distributed surface light source on the product's upper surface, greatly improving brightness uniformity and effectively solving the problem of excessively bright or dim local light. This provides a higher quality light source foundation for LCD displays and related applications, enhancing the overall visual effect and display quality.
[0021] Furthermore, in this invention, rotating the knob causes the lead screw to rotate. Since the lead screw and the movable plate are tightly fitted by threads, and the movable plate is restricted to linear sliding on two sets of rails, the rotation of the lead screw is converted into horizontal linear motion of the movable plate on the rails. The displacement of the movable plate is transmitted to the second connecting block through the first connecting plate and the second connecting plate. The second connecting block is connected to the first connecting block, and the first connecting block is connected to the clamping plate in a movable manner. With the linkage between the components, the clamping or loosening action of the clamping plate is finally realized, which improves the convenience of assembling and disassembling the light panel, effectively solves the problem of inconvenient assembly and disassembly in the prior art, and improves the efficiency and convenience of equipment maintenance and assembly.
[0022] Furthermore, in this invention, the conical spring and the connecting rod together form an effective buffer system for the motherboard. When the device is subjected to external impact or vibration caused by the movement of internal components, the motherboard will be subjected to a corresponding force. At this time, the force on the motherboard is transmitted to the movable plate through the connecting rod, and the movable plate will make a corresponding displacement within the cylinder. Since conical springs are installed at both the upper and lower ends of the movable plate, the conical springs will undergo elastic deformation due to compression during the displacement of the movable plate, thereby absorbing and storing energy. The reaction force generated by this elastic deformation can effectively offset part of the impact or vibration force acting on the motherboard, preventing the motherboard from being damaged or affecting its normal working performance due to sudden force.

[0036] Example 1: Please refer to Figures 1 to 6 :
[0037] This utility model proposes a printed light source conversion device, including: a main board 1;
[0038] The main board 1 is an optical acrylic structure board. The lower surface of the main board 1 is provided with halftone dots 11. The halftone dots 11 are spherical and arranged in a staggered rectangular array on the lower surface of the main board 1. The surface of the halftone dots 11 is printed with a reflective ink layer. The main material of the reflective ink layer is PMMA reflective particles. The upper surface of the main board 1 is provided with a convex arc structure that protrudes above the main board 1 body. Light-emitting lamp panels 27 are provided at both ends of the main board 1. Two sets of mounting seats 2 are provided on both the left and right sides of the main board 1. Side plates 21 are installed at the upper and lower ends of the mounting seats 2 by bolts. A fixing seat 22 is fixed at the end of the mounting seat 2 closest to the main board 1. Two sets of suction cups 26 are fixed on the fixing seat 22. The suction cups 26 are attached to the back of the light-emitting lamp panel 27. The function of the suction cups 26 is that the spherical halftone dot structure design, combined with its high light transmittance characteristics, can effectively refract the light from the light-emitting lamp panel 27. The halftone dots 11 are distributed in a staggered rectangular array on the lower surface of the main board 1, which cleverly avoids the problem of uneven light concentration or dispersion.
[0039] Example 2, based on Example 1,
[0040] Mounting base 2 is fixed with a first fixing plate 23 and a second fixing plate 24. Two sets of rail rods 231 are fixed between the first fixing plate 23 and the second fixing plate 24. Movable plates 233 slide on the two sets of rail rods 231. The movable plates 233 are provided with threaded holes. A lead screw 232 is installed between the first fixing plate 23 and the second fixing plate 24 through a bearing. The lead screw 232 is threadedly engaged with the threaded hole on the movable plate 233. A knob 2321 is installed on the lead screw 232 through a bolt. A hinge plate 25 is hinged to each of the two sets of side plates 21. A clamping plate 251 is fixed on the side of the hinge plate 25 near the main plate 1. The clamping plate 251 is fixed with... It has anti-slip raised particles. A round rod 252 is fixed on the side of the side plate 21 away from the main plate 1. A first connecting block 253 slides on the round rod 252. A second connecting block 254 is hinged to the first connecting block 253. A first connecting plate 2331 is connected to the second connecting block 254 and the movable plate 233 through a pin. A second connecting plate 241 is connected between the second connecting block 254 and the second fixed plate 24. Its function is to rotate the knob 2321 to rotate the lead screw 232, and finally realize the clamping or loosening action of the clamping plate 251, which improves the convenience of assembling and disassembling the light panel 27 and enhances the efficiency and convenience of equipment maintenance and assembly.
[0041] Example 3, based on Examples 1 and 2,
[0042] Four base plates 3 are arranged below the main board 1. Cylinder seats 31 are bolted to the base plates 3. The upper end of each cylinder seat 31 has a through hole. A movable disc 32 is located inside the cylinder seat 31. Conical springs 321 are installed at both the upper and lower ends of the movable disc 32. A connecting rod 33 is bolted to the upper end of the movable disc 32. The upper end of the connecting rod 33 is fixedly connected to the lower end of the main board 1. Its function is that the conical springs 321 and the connecting rod 33 together form an effective buffer system for the main board 1. When the device is subjected to external impact or vibration caused by the movement of internal components, the main board 1 will be... When the corresponding force is applied, the force on the main board 1 is transmitted to the movable plate 32 through the connecting rod 33. The movable plate 32 will then move accordingly within the cylinder seat 31. Since the upper and lower ends of the movable plate 32 are equipped with conical springs 321, the conical springs 321 will undergo elastic deformation due to compression during the displacement of the movable plate 32, thereby absorbing and storing energy. The reaction force generated by this elastic deformation can effectively offset part of the impact or vibration force acting on the main board 1, preventing the main board 1 from being damaged or its normal working performance from being suddenly subjected to force.
[0043] The working principle of this embodiment: The spherical dot structure 11, combined with its high light transmittance, can effectively refract light from the light-emitting plate 27. Distributing the dots 11 in a staggered rectangular array on the lower surface of the main board 1 cleverly avoids the problem of uneven light concentration or dispersion, allowing the light to diffuse evenly in all directions. This forms a uniformly distributed surface light source on the upper surface of the product, greatly improving brightness uniformity and effectively solving the drawbacks of excessively bright or dim local light in traditional technologies. This provides a higher quality light source for applications such as LCD displays, improving the overall visual effect and display quality. Rotating the knob 2321 causes the lead screw 232 to rotate, ultimately clamping or releasing the clamping plate 251, improving the convenience of assembling and disassembling the light-emitting plate 27 and enhancing the design. To ensure efficiency and convenience in maintenance and assembly, the conical spring 321 and the connecting rod 33 together form an effective buffer system for the main board 1. When the device is subjected to external impact or vibration caused by the movement of internal components, the main board 1 will be subjected to a corresponding force. At this time, the force on the main board 1 is transmitted to the movable plate 32 through the connecting rod 33. The movable plate 32 will then move accordingly within the cylinder seat 31. Since the upper and lower ends of the movable plate 32 are equipped with conical springs 321, during the displacement of the movable plate 32, the conical springs 321 will undergo elastic deformation due to compression, thereby absorbing and storing energy. The reaction force generated by this elastic deformation can effectively offset part of the impact or vibration force acting on the main board 1, preventing the main board 1 from being damaged or its normal working performance from being suddenly subjected to force.
