Introduction to Powerful Infrared LED

What is a Powerful Infrared LED?

A powerful infrared LED, also known as an infrared diode, is a type of semiconductor device that emits infrared light when an electric current is applied. These LEDs are widely used in various applications due to their compact size, high efficiency, and long lifespan. The term "powerful" refers to the intensity of the infrared light emitted by the LED, which is typically measured in milliwatts (mW) or watts (W). Infrared LEDs operate on the principle of the photoelectric effect, where electrons are excited within the semiconductor material when an electric current is applied. This excitation results in the emission of infrared light with a specific wavelength, which is determined by the composition of the semiconductor material.
