5mm Infrared led diode, as a vital component in the field of optoelectronics, has been widely used in various applications due to its excellent performance and cost-effectiveness. In this article, we will introduce the 5mm Infrared led diode, including its structure, working principle, application fields, and future development trends.

Introduction to 5mm Infrared led Diode

The 5mm Infrared led diode is a semiconductor light-emitting device that emits infrared light. It is named after its size, which is 5mm in diameter. This type of diode is usually made of gallium arsenide (GaAs), gallium phosphide (GaP), or other semiconductor materials. Due to its compact size and high efficiency, it has become a popular choice for many optoelectronic devices.

Structure and Working Principle

The 5mm Infrared led diode is mainly composed of three parts: the p-type semiconductor layer, the n-type semiconductor layer, and the metal contact layer. When a forward voltage is applied to the diode, electrons and holes are injected into the junction area. As the electrons and holes recombine, infrared light is emitted. The wavelength of the emitted light is determined by the composition and structure of the semiconductor material. The structure of the 5mm Infrared led diode can be divided into two types: chip-on-board (COB) and chip-on-substrate (COS). COB structure has a higher light-emitting efficiency and a longer service life, while COS structure is more suitable for mass production due to its lower cost.
