LED infrared technology has emerged as a significant player in the field of lighting and electronics, offering a range of applications from consumer products to industrial solutions. This article delves into the world of LED infrared, exploring its history, technology, applications, and future prospects.

Introduction to LED Infrared Technology

LED infrared, or Light Emitting Diode infrared, is a type of semiconductor device that emits infrared radiation when an electric current passes through it. Unlike traditional infrared sources like incandescent bulbs or heat lamps, LED infrared emits light in the infrared spectrum, which is not visible to the human eye. This technology has gained popularity due to its efficiency, long lifespan, and versatility.

History of LED Infrared Technology

The concept of LED infrared technology dates back to the early 20th century when the first light-emitting diodes (LEDs) were developed. However, it was not until the late 1980s that significant advancements in LED infrared technology began to take place. Since then, the technology has evolved rapidly, leading to the development of high-efficiency, long-lasting LED infrared devices.

How LED Infrared Works

LED infrared technology operates on the principle of semiconductors. When an electric current is applied to a semiconductor material, such as gallium arsenide or aluminum gallium arsenide, it generates infrared radiation. This process is known as electroluminescence. The semiconductor material used in LED infrared devices is carefully selected to emit the desired infrared wavelength.
