Introduction to High Power LED 780 nm

High power LED 780 nm refers to light-emitting diodes (LEDs) that emit light at a wavelength of 780 nanometers. These LEDs are known for their deep red emission, which is highly desirable in various applications, including medical, industrial, and consumer electronics. The high power aspect of these LEDs means they can produce a significantly higher luminous intensity compared to standard LEDs, making them suitable for tasks that require intense illumination.

Technology and Manufacturing

The technology behind high power 780 nm LEDs involves advanced semiconductor materials and manufacturing processes. These LEDs are typically made using gallium nitride (GaN) as the active layer, which is capable of emitting light at the desired wavelength. The manufacturing process includes epitaxial growth of the GaN layer, followed by structural modifications to enhance the LED's performance. Epitaxial growth is a critical step in the manufacturing process, as it allows for the creation of a uniform and high-quality semiconductor layer. The use of metalorganic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE) techniques ensures the growth of a thin, single-crystal layer on a substrate. This layer is then patterned and etched to form the LED structure.
