Infrared LED SMD: An Industry Overview
Introduction to Infrared LED SMD
Infrared LED SMD (Surface Mount Device) is a type of semiconductor device that emits infrared light. It has found wide applications in various fields such as consumer electronics, automotive, medical, and industrial sectors. As the demand for high-performance and energy-efficient devices continues to grow, the infrared LED SMD market is expected to witness significant growth in the coming years.
Working Principle of Infrared LED SMD
Infrared LED SMD operates on the principle of the electroluminescence effect. When a forward voltage is applied across the diode, electrons and holes recombine at the junction, releasing energy in the form of photons. These photons have a longer wavelength than visible light, falling within the infrared spectrum. The emitted infrared light is then used for various applications, such as remote control, communication, and sensing.
