Description

[Technical Field]

[0001] The present invention relates to the technical field of sight systems, and more particularly to a sight system based on the fusion of infrared photography, low-light photography and LED aiming light spot, and a sight with thermal imaging function. [Background technology]

[0002] Light emitted from an LED chip attached to a conventional firearm sight is reflected by a bonded lens to form an aiming light spot. The LED chip's emission band is 560±80nm or other bands, and the light emitted from the LED often includes various colors such as red, yellow, and green. The narrow-band interference filter film and long-wavelength cut filter film coated on the bonded lens reflect the various colors of light. Light with wavelengths of 545±15nm and longer than 600nm is reflected back to the human eye, while the human eye observes the target and its surrounding environment through the bonded lens, allowing the aiming light spot to align with the target and fire.

[0003] Patent Application No. 201920048750.4 discloses an optical system for a reflective internal red dot sight that improves monochromaticity and concealment. The system includes an LED chip and a lens used to reflect the light emitted by the LED chip. A filter sheet coated with a narrowband interference filter film is located near the LED chip and between the LED chip and the lens. This filter sheet is used to filter out broadband light other than the central wavelength emitted by the LED chip to improve the monochromaticity of the light entering the human eye. The light energy of wavelengths other than the central wavelength emitted by the filter sheet is attenuated or cut, and the light energy of the central wavelength emitted from the filter sheet is irradiated onto the adhesive reflective surface of the lens. The adhesive reflective surface is coated with a cut-off film that cuts the central wavelength, making the light emitted from the lens less detectable when viewed from a long distance, improving the concealment of the sight. Directly observing a target through the human eye is extremely difficult to accurately determine or identify the target in shooting environments with long distances or low light.

[0004] Patent Application No. 201922462324.8 discloses a two-light, three-color optical system including a green light module, a red light module, and a right-angle prism, and a sight using the system. The green light module and the red light module are arranged vertically, and the geometric center of the cubic prism is located at the intersection of the beams of light emitted from the green light module and the red light module. The cubic prism has a composite film coated on its diagonal surface, which extends along the bisector of the angle between the beams of light emitted from the green light module and the red light module. This composite film is used to completely reflect the red light emitted from the red light module and transmit the green light emitted from the green light module. By installing two light sources, one red and one green, and emitting them perpendicular to each other, green light, red light, yellow light, etc. can be generated through a control circuit using a prism and a total reflection film or a transmission film, significantly reducing the number of light sources and the volume and weight of the sight. However, with such sights, the target is still observed directly with the human eye, and it is very difficult to accurately judge or identify the target in a long distance or low light shooting environment.

Thus, features qualified by the terms "first" and "second" can explicitly or implicitly include one or more of such features. In the description of this invention, unless otherwise specified, "plurality" means two or more than two.

[0027] Example 1 This was made to solve the problem that target observation and determination are greatly affected by ambient light, which is caused by the optical system of existing sights, which require the human eye to observe the target directly.

[0028] The present invention provides a sighting system based on the integration of infrared photography, low-light photography and LED aiming light spot, as shown in Figures 1 to 4, which includes an LED graphic chip 20, a lens 3, a beam splitter 30, a display screen 31, a thermal imaging core assembly 13, a low-light night vision photography module 48, and a main control board 1, wherein the thermal imaging core assembly 13 is electrically connected to the main control board 1, the low-light night vision photography module 48 is electrically connected to the main control board 1, and the thermal imaging core assembly 13 and the low-light night vision photography module 48 are both electrically connected to the display screen 31, and the main control board The roll board 1 is electrically connected to the LED graphic chip 20 and the display screen 31, and the light emitted from the LED graphic chip 20 and the display screen 31 passes through the beam splitter 30 and enters the lens 3. The LED graphic chip 20 provides a light spot for aiming under the control of the main control board 1. The light emitted from the LED graphic chip 20 is reflected or transmitted by the beam splitter 30 and then enters the lens 3, and after being reflected by the lens 3, enters the shooter's eye 50, and the shooter's eye 50 can directly observe the target 49 and the surrounding scenery through the lens 3. In addition, the thermal imaging core assembly 13 and the low-light night vision photography module 48, under the control of the control board 1, collect video images of the target 49 and the surrounding scene. The collected video images are synchronously played back through the display screen 31, transmitted through or refracted by the beam splitter 30, then incident on the lens 3, and reflected by the lens 3 before entering the shooter's eyes 55. The source through which the shooter observes the target 49 and the surrounding scene can be the target 49 and the surrounding scene observed directly, or the recorded image of the thermal imaging core assembly 13 and the low-light night vision photography module 48 projected onto the display screen 31. This overcomes the problems of unclear observation and significant influence from environmental factors caused by existing aiming devices in which the target 49 and the surrounding scene are directly observed by the shooter through the lens 3.FIG. 4 shows a schematic diagram of the optical path of a sight system based on the integration of infrared photography, low-light photography and LED aiming light spot. From FIG. 4, it can be seen that the sight system is a reflective aiming mirror optical system, that is, the light emitted from the LED graphic chip 20 and the display screen 31 is all reflected by the lens 3 and enters the shooter's eyes 50.

[0029] Furthermore, the light incident on the beam splitter from the display screen and the light incident on the beam splitter from the LED graphic chip 20 are arranged at 90°. It should be noted that the aiming light spot emitted from the LED graphic chip 20 and the image reproduced by the display screen 31 are one reflected by the beam splitter 30 and the other passed through the beam splitter 30, as shown in Figures 2 and 3.

[0030] Furthermore, since the beam splitter 30 mainly serves to perform light fusion, the beam splitter 30 can also be replaced with a semi-transparent, semi-reflective flat reflecting mirror.

[0031] Furthermore, the sight system based on the integration of infrared photography, low-light photography and LED aiming light spot further includes a battery 14, which is electrically connected to the LED graphics chip 20, the display 31, the thermal imaging core assembly 13, the low-light night vision photography module 48 and the main control board 1, respectively, and supplies the electrical energy required for the operation of the LED graphics chip 20, the display screen 31, the thermal imaging core assembly 13, the low-light night vision photography module 48 and the main control board 1.

[0032] Furthermore, the battery 14 can be a CR123A, 18650, 18350, polymer lithium battery, etc.; the LED graphics chip 20 can be an HK-882 LED chipset; the display screen 31 can be a Micro LED or OLED; the thermal imaging core assembly 13 can be an Arrow thermal imaging core assembly; the low-light night vision module 48 can be a Sony low-light 385 or 482 low-light night vision module; and the main control board 1 can be customized to meet the needs of products that use the LED graphics chip 20, display screen 31, thermal imaging core assembly 13, and low-light night vision module 48. For example, a 21109 main control board can be developed using an HK-882 LED chipset, a Micro LED, an Arrow or Amap thermal imaging core assembly, or a Sony low-light CMOS sensor.

[0033] Furthermore, depending on the application scenario, the illustrated thermal imaging core assembly 13 and low-light night vision photography module 48 may be arranged separately from the sight. For example, the images captured by the thermal imaging core assembly 13 and low-light night vision photography module 48 can be transmitted directly to the sight or AR glasses via wireless or wired means, thereby improving the ability to identify shooting targets and expanding the application scenarios of the red dot sight. Users can freely choose to use the thermal imaging core assembly 13 or the low-light night vision photography module 48 in combination with the sight according to their own application scenario.

[0034] Example 2 Based on Example 1, the LED graphic chip can also be replaced with a Micro LED screen, in this case the system has two screens, one screen displays split images, and the other screen displays infrared photography and low-light photography images, and the light of the two paths is reflected or transmitted by the beam splitter and then enters the lens, and is reflected by the lens and enters the shooter's eyes, and the shooter can directly observe the target and surrounding images through the lens.

[0035] Example 3 Furthermore, different from Example 1 and Example 2, the sight system based on the fusion of infrared photography, low light photography and LED aiming light spot includes a lens, an OLED screen or Micro LED display, a thermal imaging core assembly, a low light night vision photography module, and a main control board, the thermal imaging core assembly is electrically connected to the main control board, the low light night vision photography module is electrically connected to the main control board, the thermal imaging core assembly and the low light night vision photography module are both electrically connected to a display screen, and the main control board is electrically connected to the OLED screen, the light emitted from the OLED screen is incident on the lens, at this time, a single OLED screen or Micro LED display is used without using a beam splitter, and two-color LEDs of the OLED screen or Micro LED display are used, green to display the fusion image and red to display the division figure, the light emitted from the OLED screen or Micro LED display is directly incident on the lens and reflected through the lens before being incident on the shooter's eyes, and the shooter can directly observe the target and surrounding images through the lens.

[0036] In summary, this sight system based on the fusion of infrared photography, low-light photography, and LED aiming light spots can assist in target observation or determination by combining infrared photography, low-light photography, and human visual observation of the target, and can further determine the target through the aim of the light spots, allowing for accurate shooting. This sight system based on the fusion of infrared photography, low-light photography, and LED aiming light spots can reduce the impact of environmental factors such as light and distance on shooting accuracy, and the method of target determination does not rely solely on human target observation, improving target identification ability and expanding the application scenarios of red dot sights.
