Introduction to 12V IR LED

The 12V IR LED is a semiconductor device that emits infrared light when an electric current passes through it. It consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared light. The 12V refers to the forward voltage required to make the LED emit light. The IR LED is a crucial component in many electronic devices, thanks to its compact size, low power consumption, and reliable performance.

Features of 12V IR LED

1. Wavelength: The 12V IR LED emits light at a wavelength of around 940nm, which is in the near-infrared region of the electromagnetic spectrum. This makes it suitable for various applications that require invisible light. 2. Emitting Angle: The emitting angle of a 12V IR LED can range from 10° to 120°, depending on the design. A narrower angle results in a more focused beam, while a wider angle provides a broader illumination area. 3. Efficiency: The efficiency of a 12V IR LED is typically between 20% and 30%. This means that for every 100mA of current, the LED can emit between 20 to 30mW of infrared light. 4. Color: The color of the 12V IR LED is usually black, which makes it less visible to the human eye. 5. Size: The size of a 12V IR LED can vary from 3mm to 10mm, depending on the application requirements.
