Introduction to Infrared Patch LEDs

What are Infrared Patch LEDs?

Infrared patch LEDs, also known as infrared surface mount LEDs, are a type of semiconductor device that emits infrared light. They are widely used in various applications, such as remote controls, security systems, and wireless communication. These LEDs have a compact size, high brightness, and low power consumption, making them ideal for modern electronic devices.

Working Principle of Infrared Patch LEDs

The working principle of infrared patch LEDs is based on the photoelectric effect. When an electric current passes through the semiconductor material, it generates infrared light. The emitted light has a wavelength range of 780nm to 3,000nm, which is beyond the visible light spectrum. This makes infrared patch LEDs invisible to the human eye, allowing them to be used in various applications without causing any interference.
