As a key component in the field of infrared technology, powerful IR LED plays a crucial role in many applications, such as remote control, communication, and security systems. This article aims to provide an in-depth introduction to the industry of powerful IR LED, covering its basic principles, application fields, market trends, and future development prospects.

Basic Principles of Powerful IR LED

Powerful IR LED is a semiconductor device that emits infrared light with high intensity. It is composed of a p-n junction, which is formed by the combination of p-type and n-type semiconductor materials. When a forward voltage is applied to the p-n junction, electrons and holes are injected into the junction. As they recombine, energy is released in the form of infrared light. The intensity of the emitted light is determined by the material properties, structure, and drive current of the LED. The key parameters of a powerful IR LED include: 1. Wavelength: The wavelength of the emitted infrared light determines its application. Common wavelengths range from 780nm to 1000nm, with 940nm being the most widely used. 2. Intensity: The intensity of the emitted light is measured in milliwatts (mW) or watts (W). The higher the intensity, the farther the detection distance and the stronger the anti-interference ability. 3. Viewing angle: The viewing angle of the LED refers to the range of angles within which the emitted light can be detected. A wider viewing angle allows for a larger detection area. 4. Forward voltage: The forward voltage is the voltage required to make the LED emit light. It varies with the material and structure of the LED. 5. Current: The current flowing through the LED affects its brightness and lifespan. Excessive current can damage the LED, while insufficient current may result in insufficient brightness.
