12V IR LED Lights: Enhance Security & Visibility Now!

With the rapid development of technology, 12V IR LED (Infrared Light Emitting Diode) has become an essential component in various industries. These diodes emit infrared light at a wavelength of around 850nm to 940nm, making them ideal for applications requiring invisible light detection and communication. This article aims to provide an in-depth introduction to the 12V IR LED industry, covering its technology, applications, market trends, and future prospects.

Technology and Manufacturing Process

12V IR LED technology is based on the semiconductor physics principle. It involves the combination of a p-type semiconductor and an n-type semiconductor to create aPN junction. When an electric current passes through this junction, electrons from the n-type semiconductor recombine with holes from the p-type semiconductor, releasing energy in the form of photons. In the case of 12V IR LED, the photons emitted are in the infrared spectrum, which is not visible to the human eye.

The manufacturing process of 12V IR LED involves several steps. First, a high-purity semiconductor material, typically gallium arsenide (GaAs), is grown using a method like molecular beam epitaxy (MBE) or chemical vapor deposition (CVD). The semiconductor wafer is then doped with impurities to create the p-type and n-type regions. Next, the wafer is etched to create a mesa structure, which acts as the base for the LED. A layer of aluminum gallium arsenide (AlGaAs) is then grown on the mesa, followed by a layer of indium gallium arsenide (InGaAs) to enhance the light emission. The top surface is then coated with a thin layer of antireflective material to improve light extraction efficiency. Finally, the wafer is diced into individual LED chips.
