With the rapid development of technology, the infrared LED (IR LED) industry has gained significant attention in recent years. As an essential component in various applications, IR LED plays a crucial role in enhancing the performance and functionality of electronic devices. This article aims to provide an in-depth introduction to the IR LED industry, covering its history, market trends, applications, and future prospects.

History of IR LED Industry

The concept of infrared radiation was discovered by Sir Isaac Newton in the 17th century. However, it was not until the late 19th century that infrared technology began to gain attention. In 1898, H. C. Powell developed the first practical infrared detection device, which marked the beginning of the infrared LED industry. Over the years, the technology has evolved, and today, IR LED is widely used in various applications.

Market Trends

The global IR LED market is projected to grow at a CAGR of 9.2% from 2020 to 2025, reaching a market size of USD 10.8 billion by 2025. The market growth can be attributed to several factors, including the increasing demand for IR LED in consumer electronics, automotive, industrial, and medical applications.
