12V IR LED, or Infrared Light Emitting Diode, has become an integral part of the modern electronics industry. This specialized type of LED emits infrared light at a specific wavelength, which is invisible to the human eye. The 12V IR LED is widely used in various applications, including security systems, remote controls, and medical devices. This article provides an in-depth introduction to the 12V IR LED industry, covering its history, technology, applications, and market trends.

History of 12V IR LED

The concept of the LED was first proposed by Oleg Vladimirovich Losev in 1927, but it wasn't until the 1960s that the first practical LED was developed by Nick Holonyak Jr. at General Electric. Since then, the LED industry has experienced rapid development, and the 12V IR LED is just one of the many types of LEDs available today. The 12V IR LED was first introduced in the 1970s and quickly gained popularity due to its low power consumption, long lifespan, and ability to emit infrared light. Over the years, the technology has evolved, and today's 12V IR LED is more efficient, reliable, and versatile than ever before.

Technology of 12V IR LED

A 12V IR LED is a semiconductor device that emits infrared light when an electric current passes through it. The key components of a 12V IR LED include the semiconductor material, the p-n junction, and the lead wires. The semiconductor material used in a 12V IR LED is typically gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs). These materials have the ability to emit infrared light when excited by an electric current. The p-n junction is the region where the p-type and n-type semiconductor materials meet. When an electric current passes through the p-n junction, it creates a potential difference, which excites the electrons in the semiconductor material and causes them to recombine, emitting infrared light. The lead wires are used to connect the 12V IR LED to the power source. The voltage across the 12V IR LED should be kept at 12V to ensure optimal performance.
