Working Principles of Infrared LED SMD

Infrared LED SMDs work on the principle of emitting infrared radiation when an electric current passes through them. These devices consist of a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared light when excited by an electric current. The emitted light is then focused into a narrow beam using a lens or a collimating lens, which ensures that the light is directed in a specific direction. The working principle of an infrared LED SMD can be summarized as follows: 1. Electric current is applied to the semiconductor material. 2. The electric current excites the electrons in the semiconductor material, causing them to recombine with the holes, releasing energy in the form of infrared light. 3. The emitted light is then focused into a narrow beam using a lens or a collimating lens.
