1. Overview of Infrared LED High Power

Infrared LED high power refers to a type of light-emitting diode (LED) that emits infrared light with high intensity. It is widely used in various fields such as industrial automation, security, medical equipment, and consumer electronics. Compared with traditional infrared light sources, infrared LED high power has the advantages of high efficiency, long life, and small size, which makes it an ideal choice for modern applications.

2. Working Principle of Infrared LED High Power

The working principle of infrared LED high power is based on the semiconductor physics. When a forward voltage is applied to the LED, electrons and holes are injected into the active region of the semiconductor material. Under the action of the electric field, electrons and holes recombine, releasing energy in the form of photons. The energy of the photons is determined by the energy gap of the semiconductor material, and infrared LED high power emits infrared light with a wavelength between 780nm and 3000nm.

3. Types of Infrared LED High Power

According to the wavelength of the emitted light, infrared LED high power can be divided into three types: near-infrared, mid-infrared, and far-infrared. The near-infrared LED high power has a wavelength range of 780nm to 1500nm, which is mainly used in remote control, optical communication, and night vision devices. The mid-infrared LED high power has a wavelength range of 1500nm to 3000nm, which is mainly used in thermal imaging, medical equipment, and environmental monitoring.
