With the rapid development of technology, the demand for high-efficiency and energy-saving lighting solutions has been increasing. Among various lighting technologies, bright IR LED (Infrared Light Emitting Diode) has gained significant attention due to its wide range of applications. This article aims to provide an in-depth introduction to the bright IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Bright IR LED

The concept of the LED (Light Emitting Diode) was first proposed by Oleg Vladimirovich Losev in 1927, and the first practical LED was invented by Nick Holonyak Jr. in 1962. However, it was not until the 1970s that infrared LEDs (IR LEDs) started to be developed for practical applications. Over the years, the technology has evolved significantly, with bright IR LEDs becoming more efficient and powerful.

Technology of Bright IR LED

Bright IR LEDs are based on the same principle as regular LEDs, where an electric current is applied to a semiconductor material to create light. The main difference lies in the material and the wavelength of the emitted light. Bright IR LEDs use specific semiconductor materials that emit infrared light, typically in the 780nm to 1400nm range. The key factors that contribute to the brightness of IR LEDs include the quality of the semiconductor material, the structure of the LED, and the drive current.
