Super bright IR LED, or Infrared Light Emitting Diode, has become an indispensable component in various industries due to its high brightness, low power consumption, and wide application range. This article will introduce the concept, development, and application of super bright IR LED, aiming to provide a comprehensive understanding of this innovative technology.

Introduction to Super Bright IR LED

Super bright IR LED is a type of light-emitting diode that emits infrared light with high brightness. It is widely used in security monitoring, remote control, and other fields. Compared with traditional IR LED, super bright IR LED has higher brightness, longer lifespan, and better performance in terms of color purity and stability.

Development of Super Bright IR LED

The development of super bright IR LED technology has a history of more than 30 years. In the early days, the brightness of IR LED was relatively low, and the application was limited. With the continuous development of semiconductor technology, the brightness of IR LED has been greatly improved. The main factors that affect the brightness of IR LED include the material, structure, and manufacturing process.

Material of Super Bright IR LED

The material of super bright IR LED is mainly InGaAsP (Indium Gallium Arsenide Phosphide) and InGaAlAsP (Indium Gallium Aluminum Arsenide Phosphide). These materials have excellent optical and electrical properties, which are conducive to the generation and transmission of infrared light. In addition, the doping concentration and layer thickness of the material also have a significant impact on the brightness of the IR LED.

Structure of Super Bright IR LED

The structure of super bright IR LED mainly includes the active layer, the cladding layer, and the contact layer. The active layer is responsible for generating and emitting infrared light, while the cladding layer is used to improve the light extraction efficiency. The contact layer is used to connect the LED with the external circuit.
