Description

Technical Field

[0001] This utility model relates to the field of optical modules, specifically to a curved UVLED optical module that is easy to splice. Background Technology

[0002] UVLED optical modules are high-efficiency optical systems that use ultraviolet light-emitting diodes as the light source. They integrate sophisticated optical design, heat dissipation management, and drive control technology, and can output ultraviolet light in specific wavelengths. Their core advantages lie in instant start-up, low power consumption, long lifespan, and support for pulsed or continuous operation modes.

[0003] In existing curved UVLED optical module splicing technology, there may be problems such as inconvenience in the splicing process, difficulty in quickly combining multiple modules, and a lack of splicing stability. During use, the spliced ​​modules are prone to loosening or separation due to factors such as vibration, and cannot guarantee stable and reliable operation. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a curved UVLED optical module that is easy to splice. It facilitates the rapid combination of multiple modules and ensures that the spliced ​​curved UVLED optical module works stably and reliably. This solves the technical problem that existing technologies cannot quickly combine multiple modules and cannot guarantee stable and reliable operation.

[0005] The objective of this utility model is achieved through the following means:

[0006] A curved UVLED optical module for easy splicing includes a mounting plate. Module bases are evenly distributed on the upper surface of the mounting plate. Each module base has a UVLED chip array on its upper surface, and an aspherical lens layer is mounted on the upper surface of each UVLED chip array. Splicing blocks are mounted on the bottom of each module base. Splicing grooves are evenly distributed on the upper surface of the mounting plate. Each splicing block is inserted into one of these grooves. An installation groove is formed inside each splicing block, and a docking block is inserted into the opening of each installation groove. A docking groove is formed on the inner wall of each splicing groove corresponding to the docking block. An electromagnet array is mounted on the inner wall of each docking groove, and the docking block is inserted into the docking groove via the electromagnet array.

[0007] Furthermore, the aspherical lens layer is composed of a continuously gradient free-form surface, and the light-emitting surface of the lens of the aspherical lens layer is attached with a light field control film. The unique curved surface design enables the light to achieve more precise focusing and diffusion when passing through the lens layer, effectively improving the utilization rate and uniformity of the light. The light field control film can flexibly adjust the propagation direction and intensity distribution of the light according to actual needs, further optimizing the optical performance of the optical module.

[0008] Furthermore, Hall sensors are installed on the inner wall of the mounting plate at positions corresponding to the electromagnet array. Mounting holes are provided at the four corners of the upper surface of the mounting plate. The Hall sensors use high-sensitivity magnetoresistive elements to monitor the changes in the magnetic field strength of the electromagnet array in real time and transmit the positioning signal to the control system to determine whether the module splicing status meets the standard. The system is notified to unlock through an external control signal. The control module reduces the magnetism of the electromagnet array. The Hall sensors detect the decrease in the magnetic field strength in the docking groove and confirm that the electromagnet array has been released from adsorption, thereby realizing the disassembly of the splicing block.

[0009] The mounting hole is a countersunk through hole with a threaded reinforcing sleeve inside, which is used to fix the mounting plate to the external bracket with bolts, while avoiding deformation caused by stress concentration.

[0010] Furthermore, the upper surface of the mounting plate is uniformly provided with heat dissipation channels, and the inner walls of the heat dissipation channels are all coated with an infrared reflective coating. The heat dissipation channels can form good air convection, accelerate the dissipation of heat inside the module, effectively reduce the operating temperature of the module, and improve its service life and stability. The infrared reflective coating can reflect the infrared radiation generated by the module back, reduce heat loss, and further improve heat dissipation efficiency.

[0011] Furthermore, a connector block is installed at the bottom of the UVLED chip array, and a connector slot is provided on the upper surface of the module base. The matching design of the connector block and the connector slot allows the UVLED chip array to be easily and quickly installed on the module base, and also facilitates subsequent disassembly and maintenance.

[0012] Furthermore, the surface of the mating block is equipped with a stop block, and the inner wall of the mounting groove is provided with a limit groove corresponding to the stop block. The stop block is movably installed inside the limit groove. The setting of the stop block and the limit groove can limit the movement range of the mating block in the mounting groove, prevent the mating block from falling off or shifting during the splicing process, and ensure the reliability of the splicing.

[0013] The beneficial effects of this utility model are as follows: preliminary splicing and positioning are achieved by inserting splicing blocks into splicing slots, which facilitates the rapid combination of multiple modules; mounting slots are opened in the splicing blocks and docking blocks are inserted therein, and docking slots are opened at corresponding positions on the inner wall of the splicing slots and electromagnet arrays are installed therein. The docking blocks are inserted into the docking slots by the electromagnet arrays, which can enhance the stability of the splicing and prevent the spliced ​​modules from loosening or separating due to vibration and other factors during use, thus ensuring that the spliced ​​curved UVLED optical modules work stably and reliably.

Aspherical lens layers 4 are installed on the upper surface of the UVLED chip arrays 3. Splicing blocks 5 are installed at the bottom of the module seats 2. Splicing grooves 6 are evenly opened on the upper surface of the mounting plate 1. The splicing blocks 5 are all inserted into the interior of the splicing grooves 6. Mounting grooves 7 are all opened inside the splicing blocks 5. Docking blocks 8 are inserted into the openings of the mounting grooves 7. Docking grooves 9 are opened on the inner wall of the splicing grooves 6 corresponding to the positions of the docking blocks 8. Electromagnetic arrays 10 are installed on the inner wall of the docking grooves 9. Docking blocks 8 are all inserted into the interior of the docking grooves 9 through the electromagnet arrays 10.

[0023] The UVLED chip array 3 is an optical component that integrates multiple ultraviolet light-emitting diode chips in a specific arrangement. It achieves high-density and high-uniformity ultraviolet output by exciting electron transitions and releasing ultraviolet photons through semiconductor materials driven by current. The array structure can flexibly adjust the chip spacing and distribution to adapt to different irradiation requirements.

[0024] The mounting plate 1 is evenly distributed with module bases 2, and a UVLED chip array 3 and an aspherical lens layer 4 are set on it. This allows for the integration of multiple UVLED chips to provide more concentrated illumination, meeting the needs of large-area or curved surface processing with specific shapes. The bottom of the module base 2 is equipped with splicing blocks 5, and splicing grooves 6 are opened on the mounting plate 1. The splicing blocks 5 are inserted into the splicing grooves 6 to achieve initial splicing and positioning, which facilitates the rapid combination of multiple modules. The splicing blocks 5 have mounting grooves 7 and insert docking blocks 8. The inner wall of the splicing grooves 6 has corresponding docking grooves 9 and an electromagnet array 10 is installed. The electromagnet array 10 makes the docking blocks 8 insert into the docking grooves 9, which can enhance the stability of the splicing and prevent the spliced ​​modules from loosening or separating due to vibration and other factors during use, ensuring that the spliced ​​curved UVLED optical modules work stably and reliably.

[0025] The aspherical lens layer 4 is composed of a continuously gradient free-form surface. The light-emitting surface of the lens layer 4 is covered with a light field control film. The unique curved surface design enables the light to achieve more precise focusing and diffusion when passing through the lens layer, effectively improving the utilization rate and uniformity of the light. The light field control film can flexibly adjust the propagation direction and intensity distribution of the light according to actual needs, further optimizing the optical performance of the optical module.

[0026] Hall sensors 11 are installed on the inner wall of the mounting plate 1 at positions corresponding to the electromagnet array 10. Mounting holes 12 are opened at the four corners of the upper surface of the mounting plate 1. The Hall sensors 11 use high-sensitivity magnetoresistive elements to monitor the changes in the magnetic field strength of the electromagnet array 10 in real time and transmit the positioning signal to the control system to determine whether the module splicing status meets the standard. The system is notified to unlock through an external control signal. The control module reduces the magnetism of the electromagnet array 10. The Hall sensors 11 detect the decrease in the magnetic field strength in the docking groove 9 and confirm that the electromagnet array 10 has been released from adsorption, thereby realizing the disassembly of the splicing block 5.

[0027] Mounting hole 12 is a countersunk through hole structure with a threaded reinforcing sleeve inside, which is used to fix the mounting plate 1 to the external bracket by bolts, while avoiding deformation caused by stress concentration.

[0028] The upper surface of the mounting plate 1 is evenly provided with heat dissipation channels 13. The inner walls of the heat dissipation channels 13 are all coated with an infrared reflective coating. The heat dissipation channels 13 can form good air convection, accelerate the dissipation of heat inside the module, effectively reduce the operating temperature of the module, and improve its service life and stability. The infrared reflective coating can reflect the infrared radiation generated by the module back, reduce heat loss, and further improve heat dissipation efficiency.

[0029] The bottom of the UVLED chip array 3 is equipped with a plug block 14, and the upper surface of the module base 2 is provided with a plug slot 15. The matching design of the plug block 14 and the plug slot 15 makes it easy and quick to install the UVLED chip array 3 onto the module base 2, and also facilitates subsequent disassembly and maintenance.

[0030] The surface of the mating block 8 is equipped with a stop block 16. The inner wall of the mounting groove 7 is provided with a limit groove 17 at the corresponding position of the stop block 16. The stop block 16 is movably installed inside the limit groove 17. The setting of the stop block 16 and the limit groove 17 can limit the movement range of the mating block 8 in the mounting groove 7, prevent the mating block 8 from falling off or shifting during the splicing process, and ensure the reliability of the splicing.

[0031] In this embodiment, the UVLED chip array 3 is installed by inserting the plug 14 into the plug slot 15 of the module base 2. The splicing block 5 at the bottom of the module base 2 is inserted into the splicing slot 6 of the mounting plate 1 to achieve initial splicing and positioning. Then, the electromagnet array 10 is used to insert the mating block 8 in the mounting slot 7 of the splicing block 5 into the mating slot 9 on the inner wall of the splicing slot 6. During this process, the stop block 16 moves in the limiting slot 17 to prevent the mating block 8 from falling off and shifting, thereby enhancing the splicing stability. At the same time, the Hall sensor 11 monitors the change in the magnetic field strength of the electromagnet array 10 in real time to determine the splicing status. Afterwards, the mounting plate 1 is fixed to the external bracket with bolts through the mounting hole 12. During operation, the UVLED chip array 3 outputs ultraviolet light, the aspherical lens layer 4 and the light field modulation film optimize the optical performance, and the heat dissipation channel 13 and the infrared reflective coating accelerate heat dissipation, ensuring the stable and reliable operation of the module.
