3mm IR LED, or Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. This compact and powerful LED is widely used in various applications, such as remote controls, security systems, and medical devices. In this article, we will delve into the industry of 3mm IR LED, exploring its features, applications, and market trends.

Introduction to 3mm IR LED

The 3mm IR LED is a small, round semiconductor device that emits infrared light. It is known for its high efficiency, long lifespan, and compact size. The diameter of the 3mm IR LED is 3mm, which makes it ideal for use in tight spaces. The device operates at a forward voltage of 1.2V to 1.8V and has a forward current of 20mA to 30mA. The wavelength of the emitted light ranges from 780nm to 950nm, which is within the infrared spectrum.

Working Principle of 3mm IR LED

The 3mm IR LED works on the principle of electroluminescence. When an electric current is applied to the semiconductor material, it generates a voltage difference across the diode. This voltage difference causes electrons and holes to recombine, releasing energy in the form of light. The emitted light is in the infrared spectrum, which is not visible to the human eye. The small size and high efficiency of the 3mm IR LED make it an excellent choice for various applications.
