Infrared emission tube (IR LED), also known as infrared emission diode, belongs to LED diode class.It is a light-emitting device that can directly convert electrical energy into near-infrared light (invisible light) and radiate it.Mainly used in various photoelectric switch, touch screen and remote control transmitting circuit.The structure and principle of infrared emitters are similar to those of ordinary light-emitting diodes, but the semiconductor chip material is different.Infrared light-emitting diodes usually use materials such as gallium arsenide (GaAs), gallium aluminide (GaAlAs) and are packaged in fully transparent or light blue, black optical grade resin.package.

The infrared transmitter generates infrared light and transmits information and commands from one device to another. Usually, one device receives the signal and then transmits the infrared (IR) signal to another device through the transmitter. According to the characteristics of the Infrared emission tube chip, It can be more widely used according to different wavelengths, such as:such as:

Wavelength: 780nm, suitable for plant lighting, medical and other fields.

Wavelength: 850nm, suitable for camera (video shooting), digital photography, monitoring, apartment intercom, anti-theft alarm, infrared waterproof.

Wavelength: 870nm, IrDA data transmission, monitoring, photoelectric interrupt, photoelectric switch, encoder and close-range infrared control application system, etc.

Wavelength: 900nm, It is suitable for detection classes,such as electrical and blood sugar.

Wavelength: 940nm, suitable for remote controls, such as those for household appliances remote controls.

Wavelength: 1050-1300-1550nm, 1450-1550-1650 is suitable for infrared physiotherapy, food testing, moisture/protein/alcohol, fiber detection, carbon monoxide/carbon dioxide, volatile strong gas detection.

Chengxingguang can provide infrared emission LED devices with a variety of packaging structures and different applications.
