Introduction to 10mm IR LED Technology

The 10mm IR LED, also known as an infrared light-emitting diode, is a semiconductor device that emits infrared light when an electric current passes through it. These LEDs are designed to emit light in the infrared spectrum, which is beyond the range of human vision. The small size of the 10mm IR LED makes it highly versatile and suitable for integration into compact devices. The technology behind the 10mm IR LED involves the use of a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared light when electrons recombine with electron holes. The size of the LED is determined by the wafer from which it is cut, with 10mm being a standard diameter for many applications.

How 10mm IR LED Works

The operation of a 10mm IR LED is based on the principle of the PN junction. When an electric current is applied to the LED, electrons from the n-type semiconductor are drawn towards the p-type semiconductor, where they recombine with electron holes. This recombination process releases energy in the form of photons, which are emitted as infrared light. The efficiency of the 10mm IR LED is determined by several factors, including the quality of the semiconductor material, the design of the LED, and the manufacturing process. Advances in technology have led to the development of high-efficiency 10mm IR LEDs that can emit a significant amount of infrared light with minimal power consumption.
