Basic Concept of Infrared Light Bead

Infrared light beads are a type of semiconductor light-emitting device that emits infrared light. They are made of gallium arsenide (GaAs), gallium phosphide (GaP), or other semiconductor materials. The infrared light emitted by the bead has a wavelength range of 700nm to 3000nm, which is invisible to the human eye. Infrared light beads have the advantages of high brightness, long life, and stable performance, and are widely used in various fields.

Development History of Infrared Light Bead

The development of infrared light beads can be traced back to the 1960s. At that time, infrared light beads were mainly used in military and aerospace fields. With the continuous development of semiconductor technology, the cost of infrared light beads has gradually decreased, and their application fields have expanded to security, medical, automotive, and consumer electronics fields. In the 1980s, the development of infrared light beads entered a rapid development period. The emergence of high-brightness, high-efficiency, and long-life infrared light beads has greatly promoted the application of infrared light beads in various fields. In the 1990s, the application of infrared light beads in security fields became more extensive, and the market demand for infrared light beads continued to grow. In the 21st century, with the continuous development of the Internet of Things, infrared light beads have become an important part of smart home, smart city, and other fields. The market demand for infrared light beads is expected to continue to rise.
