Introduction to Infrared LEDs Manufacturer

1. Definition and Overview of Infrared LEDs

Infrared LEDs, also known as infrared light-emitting diodes, are semiconductor devices that emit infrared light when an electric current passes through them. As a manufacturer of infrared LEDs, we specialize in the production of high-quality infrared light-emitting diodes for various applications. In this article, we will provide an in-depth introduction to the infrared LED industry, including its definition, classification, and applications.

2. Classification of Infrared LEDs

Infrared LEDs can be classified into several categories based on their wavelength and applications. The following are the main types of infrared LEDs: 1. Near-Infrared LEDs: With a wavelength range of 700nm to 1400nm, near-infrared LEDs are widely used in remote controls, optical communication, and barcode scanning. 2. Short-Wave Infrared LEDs: With a wavelength range of 1400nm to 1800nm, short-wave infrared LEDs are commonly used in thermal imaging, medical diagnosis, and security systems. 3. Mid-Wave Infrared LEDs: With a wavelength range of 1800nm to 3000nm, mid-wave infrared LEDs are mainly used in infrared sensors, thermal imaging, and night vision equipment. 4. Long-Wave Infrared LEDs: With a wavelength range of 3000nm to 10000nm, long-wave infrared LEDs are primarily used in thermal imaging, security systems, and scientific research.

3. Production Process of Infrared LEDs

The production process of infrared LEDs involves several steps, including material preparation, epitaxial growth, device fabrication, and packaging. The following is a brief overview of the production process: 1. Material Preparation: High-purity gallium arsenide (GaAs) and gallium nitride (GaN) are commonly used as the semiconductor materials for infrared LEDs. The materials are prepared by chemical vapor deposition (CVD) or molecular beam epitaxy (MBE) techniques. 2. Epitaxial Growth: The epitaxial layer is grown on a single crystal substrate using MBE or CVD techniques. The epitaxial layer structure includes the active region, the p-type layer, and the n-type layer. 3. Device Fabrication: The epitaxial layer is then processed into a device through photolithography, etching, and diffusion techniques. The active region is doped with impurities to create a p-n junction. 4. Packaging: The completed device is packaged using various methods, such as chip-on-board (COB), chip-on-substrate (COS), or chip-on-glass (COG) packaging. The package design ensures the device's stability and reliability.
