Introduction

Infrared LED Voltage: A Comprehensive Industry Overview

Infrared LEDs, also known as IR LEDs, have become an integral part of various industries due to their unique properties and applications. These devices emit infrared light, which is invisible to the human eye but can be detected by sensors and cameras. One of the most critical aspects of infrared LEDs is their voltage requirements, which determine their performance and efficiency. This article provides a comprehensive overview of the infrared LED voltage industry, covering its history, technology, applications, and future trends.

History of Infrared LED Voltage

The concept of infrared LEDs dates back to the early 20th century when scientists discovered that certain materials could emit infrared light when subjected to an electric current. However, it was not until the 1960s that the first practical infrared LEDs were developed. Since then, the industry has seen significant advancements in terms of efficiency, brightness, and voltage requirements.

Technology of Infrared LED Voltage

Infrared LEDs are made using semiconductor materials, primarily gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have the ability to emit infrared light when an electric current passes through them. The voltage required to operate an infrared LED depends on several factors, including the material used, the size of the LED, and the desired output.

The forward voltage of an infrared LED is the voltage required to make it emit light. Generally, the forward voltage of an infrared LED ranges from 1.2V to 3.5V, with the most common values being around 1.5V to 2.5V. The exact voltage required for a specific infrared LED can be found in its datasheet, which provides detailed information about its specifications and performance.
