This article aims to provide a comprehensive introduction to ceramic infrared LEDs, covering their technology, applications, advantages, and market trends.

Technology of Ceramic Infrared LEDs

Ceramic infrared LEDs are based on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. Unlike traditional infrared LEDs, ceramic infrared LEDs use a ceramic substrate, which offers several advantages. The ceramic material has high thermal conductivity, low thermal expansion coefficient, and excellent mechanical strength, making it ideal for withstanding high temperatures and harsh conditions.

The manufacturing process of ceramic infrared LEDs involves several steps. First, a ceramic substrate is prepared by sintering ceramic powders at high temperatures. Then, a semiconductor material, such as gallium nitride (GaN), is deposited on the substrate using methods like molecular beam epitaxy (MBE) or metal organic chemical vapor deposition (MOCVD). Next, a p-type and an n-type layer are formed on the semiconductor material to create a p-n junction. Finally, the LED is encapsulated in a ceramic package to protect it from external elements.
