12V IR LED, also known as infrared light-emitting diode, is a crucial component in various industries, particularly in the field of security, remote control, and communication. With its high efficiency, long lifespan, and compact size, 12V IR LED has become increasingly popular in modern applications. This article aims to provide an in-depth introduction to the industry of 12V IR LED, covering its working principle, applications, market trends, and future prospects.

Introduction to 12V IR LED

12V IR LED is a semiconductor device that emits infrared light when an electric current passes through it. It is made of a p-n junction, where the p-type and n-type semiconductor materials are combined. When a forward voltage is applied to the diode, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The main characteristics of 12V IR LED include:

• Low forward voltage: The typical forward voltage of a 12V IR LED is around 1.2V to 1.5V.
• High efficiency: The conversion efficiency of 12V IR LED can reach up to 20%, which is higher than other light-emitting devices.
• Long lifespan: The lifespan of a 12V IR LED can be up to 100,000 hours under normal operating conditions.
• Compact size: 12V IR LED can be designed into various sizes and shapes to meet different application requirements.

Working Principle of 12V IR LED

The working principle of a 12V IR LED is based on the p-n junction. When a forward voltage is applied to the diode, electrons from the n-type semiconductor material move towards the p-type material, while holes from the p-type material move towards the n-type material. As they reach the junction, electrons and holes recombine, releasing energy in the form of infrared light. The intensity of the light emitted depends on the material, structure, and temperature of the diode.
