Introduction to Bright IR LED Technology

Bright IR LED: What It Is

The term "bright IR LED" refers to an Infrared Light Emitting Diode that emits light at a higher intensity compared to standard IR LEDs. These diodes are designed to produce a visible light that is not visible to the naked eye, but can be detected by various sensors and cameras. The "bright" aspect of these LEDs makes them particularly useful in applications where a strong infrared signal is required, such as in security systems, remote controls, and advanced imaging technologies.

How Bright IR LEDs Work

Bright IR LEDs operate on the principle of electroluminescence, where an electric current is passed through a semiconductor material. This material, typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium nitride (InGaN), emits infrared light when the electrons recombine with the holes in the material. The intensity of the light is determined by the forward bias voltage applied to the diode.
