0805 Infrared LED Diode: A Comprehensive Industry Overview

Introduction to 0805 Infrared LED Diode

The 0805 Infrared LED Diode, also known as an infrared emitting diode, is a compact, surface-mount device that emits infrared light when an electric current is applied. This type of LED is widely used in various applications, including remote controls, proximity sensors, and communication systems. The 0805 size refers to the dimensions of the LED, which are 0.08 inches by 0.05 inches. This small form factor makes it highly suitable for space-constrained environments.

How 0805 Infrared LED Diodes Work

0805 Infrared LED Diodes operate on the principle of the光电效应. When a forward voltage is applied across the diode, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The wavelength of the emitted light typically ranges from 780 to 950 nanometers, which is outside the visible spectrum to the human eye. The efficiency of an infrared LED diode is determined by its material composition, with common materials including AlGaAs (Aluminum Gallium Arsenide) and InGaAsP (Indium Gallium Arsenide Phosphide). These materials have been optimized to emit infrared light with high efficiency and long lifetimes.
