Introduction to IR LED Chips

What are IR LED Chips?

IR LED chips, or Infrared Light Emitting Diode chips, are semiconductor devices that emit infrared light when an electric current passes through them. These chips are widely used in various applications, ranging from consumer electronics to industrial automation. The infrared light emitted by these chips is invisible to the human eye, but it can be detected by sensors and cameras, making them crucial components in many modern technologies.

How Do IR LED Chips Work?

IR LED chips operate on the principle of the electroluminescence phenomenon. When a current is applied to the semiconductor material, it generates heat, which excites the electrons within the material. As these electrons return to their ground state, they release energy in the form of photons. In the case of IR LED chips, these photons are in the infrared spectrum, which is beyond the visible range of human eyes.
