Introduction to 810 nm High Power LED

The 810 nm high power LED is a type of light-emitting diode that emits light at a wavelength of 810 nanometers. It belongs to the deep red spectrum, which is beyond the visible range of human eyes. The primary advantage of this LED is its high power output, making it suitable for various applications such as medical, industrial, and scientific fields.

Manufacturing Process of 810 nm High Power LED

The manufacturing process of 810 nm high power LED involves several critical steps. Here is an overview of the process:

1. Crystal Growth: The first step is to grow a high-quality crystal of the semiconductor material. This material is typically gallium nitride (GaN) or aluminum gallium nitride (AlGaN), which can emit light at the desired wavelength.

2. Layer Deposition: After the crystal is grown, multiple layers of the semiconductor material are deposited on the crystal to create a p-n junction. This junction is essential for the LED to emit light.

3. Etching and Dicing: The crystal is then etched and diced into individual LED chips. This process involves removing the unnecessary material and cutting the crystal into small, precise chips.

4. Bonding: The LED chips are bonded to a metal substrate using silver paste. This process ensures electrical contact between the chip and the substrate.

5. Encapsulation: Finally, the LED chip is encapsulated in a clear, transparent material to protect it from external factors such as moisture and temperature.
