Red IR LED, short for red infrared light-emitting diode, is a type of semiconductor device that emits infrared light in the red spectrum. As an important part of the infrared technology industry, red IR LED has been widely used in various fields such as remote control, security monitoring, medical equipment, and industrial automation. This article will introduce the industry of red IR LED, including its working principle, application fields, market status, and future development trends.

Working Principle of Red IR LED

The working principle of red IR LED is based on the semiconductor physics. When a forward voltage is applied to the PN junction of the diode, electrons and holes are recombined, releasing energy in the form of photons. The energy of the photons determines the wavelength of the emitted light. The longer the wavelength, the lower the energy. The red IR LED emits light in the red spectrum, which is why it is called red IR LED.

Application Fields of Red IR LED

Red IR LED has a wide range of application fields due to its excellent performance. The following are some typical application fields:

1. Remote Control
