What is a Infrared LED?

An infrared LED (Light Emitting Diode) is a type of LED that emits infrared radiation, which is invisible to the human eye. Infrared light has longer wavelengths than visible light and is commonly used in applications like communication, security, remote controls, surveillance cameras, and night vision. For instance, infrared LEDs are used in remote controls to transmit signals to devices like televisions and air conditioners. In surveillance cameras, infrared LEDs allow the camera to capture clear video footage in low-light or dark conditions, enabling night vision capabilities.

Application of Infrared LED

Example 1: Remote Controls Infrared LEDs are used in remote controls for household devices like televisions and air conditioners. When a button is pressed on the remote, the infrared LED emits a signal to communicate with the device, allowing users to control various functions.

Example 2: Surveillance Cameras Infrared LEDs are integrated into surveillance cameras to enable clear footage even in low-light or nighttime conditions. The infrared LEDs provide illumination, allowing the camera to offer night vision capabilities and capture sharp images in the dark.

Example 3: Biometric Systems Infrared LEDs are also used in biometric authentication systems, such as fingerprint or facial recognition. The infrared LEDs illuminate the fingerprint or face, enabling the system to capture detailed information for identification purposes.
