Powerful infrared LED, also known as high-power infrared LED, is a type of light-emitting diode that emits infrared light with high intensity. In recent years, with the rapid development of technology, powerful infrared LED has been widely used in various fields such as security monitoring, medical equipment, automotive lighting, and consumer electronics. This article will introduce the development, application, and future prospects of powerful infrared LED in the industry.

Development of Powerful Infrared LED

The development of powerful infrared LED can be traced back to the 1960s. At that time, with the continuous improvement of semiconductor technology, the red LED was successfully developed. Later, people began to study the infrared LED. In the 1970s, the first infrared LED was developed and applied in the field of remote control. With the continuous optimization of technology, the power of infrared LED has been greatly improved. In the early stage of the development of powerful infrared LED, the main material was gallium arsenide (GaAs). Due to the limitation of material properties, the luminous intensity and lifespan of the infrared LED were relatively low. In the 1980s, the material of infrared LED was gradually replaced by gallium nitride (GaN). GaN has excellent optical, electrical, and thermal properties, which greatly improves the performance of infrared LED. In recent years, with the continuous development of semiconductor technology, the structure and material of infrared LED have been further optimized. The use of multi-quantum well structure, AlGaInAs/GaAs structure, and other advanced structures can effectively improve the luminous intensity and lifespan of infrared LED. At the same time, the development of epitaxial technology has also greatly promoted the progress of infrared LED.
