Super bright 5mm IR LED, or Infrared Light Emitting Diode, has become a staple in various industries due to its compact size, high brightness, and versatile applications. This article aims to provide a comprehensive introduction to the world of super bright 5mm IR LEDs, covering their history, technology, applications, market trends, and future prospects.

Introduction to Super Bright 5mm IR LED

The super bright 5mm IR LED is a type of semiconductor device that emits infrared light when an electric current is applied. These LEDs are known for their small size, typically measuring only 5mm in diameter, which makes them highly suitable for space-constrained applications. The "super bright" aspect refers to their high luminous intensity, which is significantly greater than that of traditional IR LEDs.

History of Super Bright 5mm IR LED

The development of IR LEDs dates back to the early 1960s when Nick Holonyak, a physicist at General Electric, successfully demonstrated the first practical LED. Since then, the technology has evolved rapidly, with significant advancements in efficiency, brightness, and lifespan. The 5mm IR LED became popular in the 1990s, as it offered a balance between size, brightness, and cost-effectiveness.

Technology Behind Super Bright 5mm IR LED

Super bright 5mm IR LEDs are made of gallium arsenide (GaAs) or gallium phosphide (GaP) semiconductor materials. These materials have direct bandgap properties, which allow them to emit light at specific wavelengths when an electric current passes through them. The process of creating an IR LED involves epitaxial growth, where layers of semiconductor materials are deposited on a substrate to form a p-n junction. The key factors that contribute to the brightness of a 5mm IR LED include the quality of the semiconductor material, the thickness of the active layer, and the efficiency of the device. Modern manufacturing techniques have improved the performance of these LEDs, resulting in higher brightness levels and longer lifespans.
