[0002] The infrared flashlight is a lighting tool that emits infrared light (invisible light) and is usually used in scenes that require covert lighting or special applications. It is designed to be used with night vision devices and infrared cameras and can provide lighting in completely dark environments without exposing visible light.

[0003] Infrared light mainly uses infrared emission technology. Infrared rays are electromagnetic waves with longer wavelengths than visible light and cannot be directly seen by the human eye. Infrared fill light emits infrared light waves to provide lighting in night or low-light environments. Since infrared light has low dependence on light, infrared fill light can provide effective lighting in complete darkness, but its imaging effect is usually in black and white tones, which cannot restore the true color of the object. Infrared light plays an important role in improving efficiency, accuracy, and safety due to its high brightness, precision, and stability. The versatility and practicality of infrared flashlights make them an important tool in various application scenarios. Whether used as an auxiliary search tool for night-time outdoor hunting digital scopes, monitoring equipment, measuring equipment, or signaling devices, infrared light is indispensable, especially in night-time or low-light environments. For example, in outdoor activities such as hiking and trekking, infrared flashlights can be used to guide directions or visually communicate with other team members.

[0027] The present application provides an infrared flashlight, which is used for assisting night vision instrument, infrared camera and other equipment to provide illumination at night, and the application scenarios include night outdoor environment or other relatively dark environment.

[0028] The infrared flashlight comprises a lens barrel 1, a first knob 101 arranged outside the lens barrel 1, and a lens 102 arranged inside the lens barrel 1; a rotating part 2 arranged inside the lens barrel 1 and connected with the first knob 101, and provided with a first infrared emitting unit 201 and a second infrared emitting unit 202, and the lens 102 is used for transmitting light emitted by the first infrared emitting unit 201 and the second infrared emitting unit 202 respectively. The lens barrel 1 is a main irradiation component.

[0029] In implementation, the first knob 101 is arranged outside the lens barrel 1, the lens 102 is arranged inside the lens barrel 1, the first infrared emitting unit 201 and the second infrared emitting unit 202 are arranged on the rotating part 2, the rotating part 2 is specially arranged in the lens barrel 1, the first knob 101 is connected with the rotating part 2, and after assembly, the first infrared emitting unit 201 can be aligned with the lens 102 or the second infrared emitting unit 202 can be aligned with the lens 102. If the first infrared emitting unit 201 is aligned with the lens 102, the lens 102 transmits the infrared rays emitted by the first infrared emitting unit 201. By manually rotating the first knob 101 outside the lens barrel 1, the first knob 101 drives the rotating part 2, and the second infrared emitting unit 202 on the rotating part 2 is turned to align with the lens 102. At this time, the lens 102 transmits the infrared rays emitted by the second infrared emitting unit 202. By driving the rotating part 2 through the first knob 101, the positions of the first infrared emitting unit 201 and the second infrared emitting unit 202 are changed, different infrared rays are transmitted by the lens 102, and thus the infrared flashlight can adapt to different application scenarios.

[0030] Specifically, the first infrared emitting unit 201 transmits infrared rays with a wavelength of 940 nm. The 940 nm emitting tube has a relatively long wavelength, which can penetrate some objects, so that it has certain advantages in infrared communication and detection. The 940 nm wavelength is completely invisible, and is suitable for scenes such as military, hunting, monitoring and the like which need to be hidden. The second infrared emitting unit 202 transmits infrared rays with a wavelength of 850 nm. The infrared rays with a wavelength of 850 nm can provide brighter infrared illumination due to the slightly shorter wavelength, and are suitable for illumination requirements in some low-light environments, such as home security or outdoor exploration. The outer wall of the lens barrel 1 is provided with a through hole, the first knob 101 is provided with a connecting shaft, and the connecting shaft of the first knob 101 passes through the through hole in the outer wall of the lens barrel 1 and is connected with the rotating part 2.

When the light emitted by the second infrared emission unit 202 needs to be adjusted, the rotating member 2 is driven by the first knob 101.
