Surface mount IR LED, or surface mount infrared LED, is a type of LED that emits infrared light. As a crucial component in various applications, such as consumer electronics, automotive, and industrial automation, it has become increasingly popular in the global market. This article aims to provide an in-depth introduction to the surface mount IR LED industry, covering its development history, application fields, market trends, and future prospects.

Development History of Surface Mount IR LED

Surface mount IR LED technology has undergone a long and tortuous development process. In the early days, IR LED technology was mainly based on the traditional through-hole packaging. However, due to the limitations of through-hole packaging, such as high assembly cost and low density, the development of IR LED technology was slow. With the continuous development of semiconductor technology, surface mount packaging technology emerged, and surface mount IR LED technology gradually replaced traditional through-hole packaging. In the 1980s, the surface mount technology was first introduced to the LED industry. However, due to the high cost and technical difficulties, the application of surface mount IR LED was relatively limited. In the 1990s, with the continuous improvement of surface mount technology and the reduction of production costs, the application of surface mount IR LED began to expand. By the 21st century, surface mount IR LED had become the mainstream packaging technology in the LED industry.
