IR LEDs for night vision have become an indispensable technology in various fields, such as military, security, and wildlife observation. This article will introduce the industry of IR LEDs for night vision, including their working principles, applications, and future development trends.

Working Principles of IR LEDs for Night Vision

IR LEDs for night vision are based on the principle of infrared light. Unlike visible light, infrared light has a longer wavelength and cannot be seen by the human eye. When the infrared light emitted by IR LEDs is reflected off objects, it can be captured by a camera or sensor, and then converted into a visible image. This process allows us to see in the dark or in low-light conditions.

IR LEDs can be divided into two types: semiconductor IR LEDs and infrared phosphorescent lamps. Semiconductor IR LEDs have higher efficiency and better performance, while infrared phosphorescent lamps have lower cost and longer lifespan. In the field of night vision, semiconductor IR LEDs are more commonly used.

Applications of IR LEDs for Night Vision

IR LEDs for night vision have a wide range of applications, including:

• Military and Defense: IR LEDs are used in night vision devices, such as binoculars, scopes, and cameras, to enable soldiers to see in the dark, thereby enhancing their combat effectiveness.
