Market Trends

The infrared LED market has been witnessing significant growth over the past few years, driven by the increasing adoption of infrared technology in various applications. According to a report by MarketsandMarkets, the global infrared LED market is expected to reach USD 5.5 billion by 2025, with a CAGR of 9.5% during the forecast period.

One of the major factors driving the market growth is the rising demand for infrared sensors in consumer electronics, such as smartphones, cameras, and gaming devices. Additionally, the increasing use of infrared technology in automotive and medical applications has further contributed to the market growth.

Production Process

The production process of infrared LED involves several steps, starting from the raw material preparation to the final product packaging. Here is a brief overview of the production process:

• Raw Material Preparation: The primary raw materials required for infrared LED production are gallium arsenide (GaAs), gallium phosphide (GaP), and gallium nitride (GaN). These materials are processed to obtain high-purity ingots, which serve as the base for the LED chips.
• Epitaxial Growth: The high-purity ingots are then subjected to epitaxial growth, where a thin layer of semiconductor material is deposited on a substrate. This process is crucial for achieving the desired electrical and optical properties of the infrared LED.
• Structural Fabrication: The epitaxial wafer is then processed to create the LED structure, which includes the p-n junction, mirror layer, and package materials. This step involves various techniques, such as doping, etching, and sputtering.
• Testing and Sorting: After the structural fabrication, the infrared LED chips are tested for their electrical and optical characteristics. The chips are then sorted based on their performance, with high-quality chips being selected for further processing.
• Package and Testing: The sorted infrared LED chips are mounted on a package substrate and encapsulated with a transparent or reflective material. The packaged LEDs are then tested for their electrical and optical performance before being shipped to customers.
