12V IR LED, or Infrared Light Emitting Diode, has become an integral part of modern technology, particularly in the fields of security, automation, and remote control systems. This article aims to provide a comprehensive introduction to the 12V IR LED industry, covering its history, technology, applications, and future trends.

History of 12V IR LED

The concept of the LED, or Light Emitting Diode, was first proposed by Oleg Vladimirovich Losev in 1927. However, it was not until the 1960s that the first practical LED was developed by Nick Holonyak Jr. at General Electric. Since then, LED technology has rapidly evolved, and today, it is widely used in various applications, including 12V IR LED. The 12V IR LED was first introduced in the 1970s, primarily used in remote control devices and security systems. Over the years, the technology has improved significantly, with higher brightness, longer lifespan, and better heat dissipation. Today, 12V IR LED is an essential component in many electronic devices.

Technology of 12V IR LED

A 12V IR LED is a semiconductor device that emits infrared light when an electric current is applied. It consists of a p-n junction, where the p-type and n-type materials are doped with impurities to create a forward-biased junction. When the forward voltage is applied, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The key characteristics of a 12V IR LED include its forward voltage, forward current, and luminous intensity. The forward voltage is the voltage required to turn the LED on, while the forward current is the current that flows through the LED when it is turned on. The luminous intensity is a measure of the light emitted by the LED. The 12V IR LED is available in various packages, such as the TO-5, TO-18, and SMD packages. The TO-5 package is the most common, while the SMD package is widely used in surface-mounted applications.
