Introduction to Infrared LED Chip Industry

Infrared LED Chip: A Brief Overview

The infrared LED chip, also known as an infrared emitting diode, is a semiconductor device that emits infrared light when an electric current is applied to it. It is widely used in various applications, including remote controls, surveillance systems, and automotive lighting. The infrared LED chip industry has witnessed significant growth over the years, driven by advancements in technology and increasing demand across different sectors.

History and Evolution

The concept of the infrared LED chip dates back to the early 20th century when the first semiconductor devices were developed. However, it was not until the late 1960s that the first practical infrared LED was invented. Since then, the industry has evolved rapidly, with continuous improvements in efficiency, brightness, and cost-effectiveness.

In the early days, infrared LED chips were primarily used in simple applications such as remote controls. As technology progressed, the demand for more advanced and efficient infrared LED chips increased, leading to the development of high-brightness, high-efficiency, and wide-range infrared LED chips.

Working Principle

The working principle of an infrared LED chip is based on the photoelectric effect. When an electric current is applied to the semiconductor material, electrons are excited and move to higher energy levels. As they return to their original energy levels, they release energy in the form of photons. These photons are in the infrared spectrum, which is not visible to the human eye.

The semiconductor material used in infrared LED chips is typically a compound semiconductor, such as gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to efficiently emit infrared light.
