Technology of High Power LED 850nm

High power LED 850nm refers to light-emitting diodes that emit light at a wavelength of 850 nanometers. These LEDs are typically made of gallium nitride (GaN) as the main material, which is known for its high thermal conductivity and electrical conductivity. The technology of high power LED 850nm involves several key processes: 1. Material Growth: The first step in producing high power LED 850nm is to grow a high-quality GaN layer on a substrate, usually sapphire or silicon carbide (SiC). This process requires high temperatures and pressures, and the quality of the GaN layer directly affects the performance of the LED. 2. Epitaxial Growth: After the GaN layer is grown, epitaxial growth is performed to deposit additional layers, such as aluminum gallium nitride (AlGaN) and indium gallium nitride (InGaN), on top of the GaN layer. These layers determine the emission wavelength and color of the LED. 3. Quantum Well Structure: Quantum well structures are formed by sandwiching InGaN layers between AlGaN layers. The thickness of the quantum well determines the emission wavelength, with 850nm being a common choice for certain applications. 4. Device Fabrication: The final step involves fabricating the LED device, which includes etching, bonding, and encapsulating the epitaxial layer. The encapsulation process ensures that the LED can operate at high power without overheating.
