With the rapid development of technology, the demand for high-power infrared (IR) LEDs has been on the rise. One such powerful LED is the 1W IR LED, which has become a crucial component in various applications, ranging from automotive sensors to industrial automation. This article aims to provide an in-depth introduction to the 1W IR LED industry, covering its technology, applications, market trends, and future prospects.

Introduction to 1W IR LED Technology

The 1W IR LED, as the name suggests, is an infrared light-emitting diode that emits light with a power output of 1 watt. It operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. These LEDs are characterized by their high efficiency, long lifespan, and compact size, making them ideal for a wide range of applications.

Working Principle of 1W IR LED

1W IR LEDs are based on the same semiconductor materials as standard LEDs, but with higher power output capabilities. The most common materials used in the manufacturing of IR LEDs are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to emit infrared light efficiently.

When an electric current is applied to the LED, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. The wavelength of the emitted light depends on the composition of the semiconductor material. For 1W IR LEDs, the typical wavelength range is between 780 nm to 950 nm, which falls within the near-infrared spectrum.
