Infrared LED is LEDs that can emit near-infrared light of about 700~1,500 nm.
Infrared light is highly transparent and is not easily affected by obstacles. Since it is invisible to the human eye, this wavelength is often used for signal transmission and reception, various sensors, and light sources in dark areas. Other sources of infrared light include lasers, but LEDs have the advantages of mass production, long life, shock resistance, and low cost.
The most familiar being remote controls for TVs, air conditioners, and other devices. Other cameras equipped with infrared LEDs are sometimes used for nighttime photography, such as security cameras. Infrared light is also often used as a measurement light because of its high transmittance and low susceptibility to obstructions. Recently, infrared light is sometimes used as a light source for LiDAR and TOF cameras, the latest light-based ranging technology.
Infrared light is also used to measure water content in samples due to the fact that infrared light is easily absorbed by water.
The light emission principle of LEDs is the same regardless of wavelength and is based on the p-n junction of semiconductors: holes move through p-type semiconductors when an electric field is applied, while electrons move through n-type semiconductors. Energetically, the electrons in the n-type semiconductor are higher, creating a gap between the energy band of the p-type semiconductor and the energy band of the hole in the p-type semiconductor. When an electric field is applied to perturb the electrons and holes, a transition of electrons from the n-type energy band to the p-type energy band occurs. When the electrons and holes collide, light and heat corresponding to the energy gap are generated and disappear. Since the size of the energy band gap depends on the composition of each semiconductor, the wavelength of the light emitted can be tuned by combining various materials. Aluminum gallium arsenide (AlGaAs) is often used to output wavelengths in the near-infrared band.
In general, infrared LEDs are less efficient than LEDs in the visible light range.
Infrared LEDs lights are representative of products using infrared LEDs. The following is a list of typical types.
This is a new way to use infrared LEDs, which are attracting attention as room interior decorations. The other side of the tape has an adhesive side for easy attachment, and a wide variety of types are available, including those with waterproofing and those that are thinner than 3 mm for use in confined spaces.
Infrared LEDs are used in the light transmitting part of most home appliance remote controls.
