Surface mount IR LED, also known as surface mount infrared LED, is a type of light-emitting diode that emits infrared light. It is widely used in various fields such as security, communication, medical equipment, and consumer electronics. In this article, we will introduce the industry of surface mount IR LED, including its working principle, application fields, market trends, and future development prospects.

Working Principle of Surface Mount IR LED

Surface mount IR LED is a semiconductor device that emits infrared light when an electric current passes through it. The working principle is based on the photoelectric effect of semiconductors. When the electric current passes through the semiconductor material, electrons and holes are generated, and the recombination of electrons and holes releases energy in the form of photons. These photons have a wavelength in the infrared range, which is why it is called an infrared LED. The structure of a surface mount IR LED generally includes a semiconductor chip, a lead frame, and a package. The semiconductor chip is the core part of the LED, which emits infrared light. The lead frame is used to connect the semiconductor chip to the external circuit. The package is used to protect the semiconductor chip and ensure its stable operation.
