The 4mm infrared LED diode is a popular choice among manufacturers and consumers due to its compact size, high efficiency, and reliability. In this article, we will provide a comprehensive overview of the 4mm infrared LED diode industry, covering its history, applications, market trends, and future prospects.

History of Infrared LED Diodes

The concept of infrared LED diodes dates back to the early 20th century when scientists discovered that certain materials could emit infrared radiation when an electric current was applied to them. However, it was not until the 1960s that the first practical infrared LED diodes were developed. Since then, the technology has evolved significantly, with advancements in materials, design, and manufacturing processes leading to the production of high-quality, efficient infrared LED diodes.

How 4mm Infrared LED Diodes Work

A 4mm infrared LED diode consists of a semiconductor material, typically gallium arsenide (GaAs), that emits infrared light when an electric current is applied. The diode is encapsulated in a clear or colored plastic lens to protect the semiconductor material and to focus the emitted light. The size of the diode is determined by the diameter of the lens, which is typically 4mm in diameter. When an electric current is applied to the diode, the electrons and holes in the semiconductor material recombine, releasing energy in the form of infrared light. The intensity of the light emitted depends on the forward voltage applied to the diode and the current flowing through it. By adjusting the forward voltage and current, the output power of the 4mm infrared LED diode can be controlled.
