[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0033] Refer to Figures 1-4, an embodiment provided by the present utility model: an optical path structure applied to low-temperature superconductivity, including an upper cover 6 and a lower cover 15. A double-fin LED radiator 18 is fixedly connected to the top of the lower cover 15. An LED light board 7 is fixedly connected to one side of the double-fin LED radiator 18. An optical funnel 8 is arranged on one side of the LED light board 7. An internal circulation fan 14 is fixedly connected to the top of the lower cover 15. A radiator fan A 16 and a radiator fan B 17 are fixedly connected to the top of the lower cover 15. An internal circulation sealing cover 1 is arranged on the top of the upper cover 6. An internal circulation U-shaped radiator A 2 is fixedly connected to the side of the radiator fan B 17 away from the double-fin LED radiator 18. An internal circulation U-shaped radiator B 3 is fixedly connected to the side of the radiator fan A 16 away from the double-fin LED radiator 18. Lenses 13 are fixedly connected to the middle parts of the lower cover 15 and the upper cover 6. A centering element 9 is arranged on the side of the optical funnel 8 away from the LED light board 7. An LED screen assembly 11 is arranged on the top of the lower cover 15. The function of the LED screen assembly 11 is to optimize and protect the optical performance and stability of optical elements. By supplying power to light up the LED light board 7, the light source sequentially passes through the optical funnel 8, the centering element 9, the heat-insulating glass 10, the LED screen assembly 11, the coating 12, and finally passes through the lens 13 and projects onto the wall or the curtain to present an image. The LED light board 7 is the main heat source. The heat dissipation of the LED light board 7 relies on the heat conduction of the internal circulation U-shaped radiator A 2 and then the air flow heat dissipation through the radiator fan A 16 and the radiator fan B 17. At the same time, because the heat source of the LED light board 7 irradiates the whole interior, the temperature inside the optical path structure is very high, which directly affects the LED screen assembly 11 and may cause the phenomenon of being scorched, resulting in the image turning black. An internal circulation fan 14 is added inside to blow air. First, the air passes through the middle of the coating 12 and the LED screen assembly 11 to take away the heat of the LED screen assembly 11 and ensure the normal temperature operation of the screen. Then, the air passes through the internal circulation U-shaped radiator A 2. The heat inside the internal circulation U-shaped radiator A 2 will be conducted from one end inside to the other end outside and then be sucked away by the radiator fan B 17. The air flow continues to pass through the LED screen assembly 11 inside the machine to continue taking away the heat of the LED screen assembly 11 and ensure the normal temperature operation of the screen. Then, the air passes through the internal circulation U-shaped radiator B 3. The internal circulation U-shaped radiator B 3 has the same working principle as the internal circulation U-shaped radiator A 2. The internal heat passes through and is conducted to the other end outside and then is sucked away by the double-fin LED radiator 18. The air continues to pass through the internal circulation U-shaped radiator B 3 and returns to the air inlet of the internal circulation fan 14, realizing the internal heat dissipation cycle of this structure, reasonably optimizing the air duct, improving the heat dissipation efficiency, avoiding damage or performance degradation of electronic components caused by overheating, and effectively improving the practicality of this structure.
[0034] Refer to Figures 1-5, the LED screen assembly 11 includes a bracket A 11-1, the bracket A 11-1 is fixedly connected to the top of the lower cover 15, one side of the bracket A 11-1 is fixedly connected to an LED screen 11-2, the side of the LED screen 11-2 away from the bracket A 11-1 is fixedly connected to a bracket B 11-3, a coating 12 is arranged on the side of the bracket B 11-3 away from the LED screen 11-2, a heat-insulating glass 10 is arranged on one side of the center 9. Through the composite layer arrangement of the bracket A 11-1, the LED screen 11-2, and the bracket B 11-3, the support strength of the LED screen assembly 11 is effectively improved. Through the laminated arrangement of the heat-insulating glass 10 and the coating 12, the effective management of the surrounding heat is realized, the service life of each optical element inside the optical path structure is prolonged, the aging or damage of the components caused by overheating or heat influence is reduced, and the performance and stability of the optical structure are greatly optimized.
[0035] Referring to Figures 1-5 , both the LED light board 7 and the light bucket 8 are arranged between the radiator fan A 16 and the radiator fan B 17. The LED light board 7 is used to provide light sources, and the light bucket 8 is used to assist the propagation of light sources. A motor 4 is fixedly connected to the middle of the lens 13, the output end of the motor 4 is fixedly connected to a gear 5, and the gear 5 is meshed and connected to the outside of the lens 13. The lens 13 is used to adjust and control the focal length and size of the projection. There are specifically multiple LED radiator double fins 18, and multiple LED radiator double fins 18 are all fixedly connected to the bottom of the upper cover 6. The LED radiator double fins 18 are used for heat dissipation and temperature reduction to maintain the normal working temperature inside. The material of the light bucket 8 is specifically set as 98 aluminum to provide better reflectivity and stability for the light bucket 8. The material of the bracket A 11-1 is specifically set as polyethylene to provide electrical insulation for the bracket A 11-1. The material of the bracket B 11-3 is specifically set as aluminum alloy to provide good support and high-temperature tolerance for the bracket B 11-3. A buckle pin 19 is slidably connected to the outside of the LED radiator double fins 18, and the LED screen assembly 11 is arranged on the top of the inner circulation seal cover 1. The buckle pin 19 is used to fix the LED radiator double fins 18.
[0036] Working principle: First, power is supplied to light up the LED light board 7. The light source passes through the light bucket 8, the centering element 9, the heat-insulating glass 10, the LED screen assembly 11, the coating 12, and finally passes through the lens 13 and projects onto the wall or screen to show the picture. The LED light board 7 is the main heat source. The heat dissipation of the LED light board 7 relies on the heat conduction of the internal circulation U-shaped radiator A2, and then the heat is dissipated by the air flow of the radiator fan A16 and the radiator fan B17. At the same time, because the heat source of the LED light board 7 irradiates the whole interior, the temperature inside the optical path structure is very high, which directly affects the LED screen assembly 11 and causes the phenomenon of burning, resulting in the picture turning black. An internal circulation fan 14 is added to blow air. First, it passes through the middle of the coating 12 and the LED screen assembly 11 to take away the heat of the LED screen assembly 11 and ensure the normal temperature operation of the screen. Then it passes through the internal circulation U-shaped radiator A2. The heat inside the internal circulation U-shaped radiator A2 will be conducted from one end inside to the other end outside, and then the heat source is sucked away by the radiator fan B17. The air flow continues to pass through the LED screen assembly 11 inside the machine, continues to take away the heat of the LED screen assembly 11 to ensure the normal temperature operation of the screen, and then passes through the internal circulation U-shaped radiator B3. The internal circulation U-shaped radiator B3 has the same working principle as the internal circulation U-shaped radiator A2. The internal heat passes through and is conducted to the other end outside, and then the heat source is sucked away by the double fins of the LED radiator 18. The air continues to pass through the internal circulation U-shaped radiator B3 and returns to the air inlet of the internal circulation fan 14, realizing the internal heat dissipation cycle of this structure, reasonably optimizing the air duct, improving the heat dissipation efficiency, avoiding the damage or performance degradation of electronic components caused by overheating, and effectively improving the practicability of this structure.
[0037] Secondly, through the composite layer setting of the bracket A11-1, the LED screen 11-2, and the bracket B11-3, the support strength of the LED screen assembly 11 is effectively improved. Through the laminated setting of the heat-insulating glass 10 and the coating 12, the effective management of the surrounding heat is realized, the service life of each optical element inside the optical path structure is prolonged, the aging or damage of the components caused by overheating or heat influence is reduced, and the performance and stability of the optical structure are greatly optimized.
