IR LEDs are diodes that emit infrared light from electronic devices that are not visible to the naked eye. This infrared light can be used for remote control, to transmit data between devices, to provide illumination for night vision devices, or for a variety of other purposes, and is the most common type of light used in remote control devices and security systems worldwide. This article will describe several of its common uses.
IR LEDs are commonly used in security cameras to enable the camera to capture daytime and nighttime images. Infrared light waves are invisible to the human eye but will be emitted by any object that emits heat. Infrared cameras usually have a sensor system that monitors the light level in the recording area.
A very common place for IR LEDs is in the remote control of a TV or other device. One or more LEDs inside the remote control transmit fast pulses of infrared light to a receiver on the TV. The receiver then decodes these pulses and interprets them as commands and performs the desired action.
Infrared light can also be used to transfer data between electronic devices. Cell phones, personal digital assistants, and some computers may have infrared LEDs and receivers designed for data transmission over short distances. Some wireless keyboards and computer mice also use IR LEDs and receivers instead of cables.
IR LED technology is ideal for applications such as security systems and night vision goggles. Many cameras use IR LEDs to provide night vision mode. Some flashlights with IR LEDs can provide additional lighting for night vision cameras or devices.
IR LEDs have a variety of other uses. The U.S. Food and Drug Administration has approved several products with IR LEDs for medical or cosmetic procedures. Robots can use IR LEDs to detect objects, and some utility meters even have an IR LED that can transmit data to a tool for a meter reading.
