Definition and Types of Infrared Emitter LED

Infrared emitter LED is a semiconductor device that emits infrared light when an electric current passes through it. It is widely used in various fields due to its excellent performance, such as low power consumption, long service life, and stable light output. According to the wavelength of the emitted light, infrared emitter LED can be divided into three types: near-infrared, mid-infrared, and far-infrared.

Near-infrared infrared emitter LED has a wavelength range of 780nm to 2500nm, which is closest to the visible light spectrum. It is often used in remote control, infrared communication, and infrared imaging. Mid-infrared infrared emitter LED has a wavelength range of 2.5μm to 50μm, which is mainly used in thermal imaging, gas sensing, and medical diagnostics. Far-infrared infrared emitter LED has a wavelength range of 50μm to 1000μm, which is mainly used in thermal imaging, long-distance communication, and industrial heating.
