High power 405nm LED has emerged as a crucial component in various applications, ranging from optical communication to medical devices. This article aims to provide an in-depth introduction to the high power 405nm LED industry, covering its technology, applications, market trends, and future prospects.

Technology of High Power 405nm LED

High power 405nm LED is a type of light-emitting diode (LED) that emits light at a wavelength of 405 nanometers. The technology behind these LEDs involves the use of gallium nitride (GaN) as the semiconductor material. The GaN-based LED emits blue light, which is then converted into green light through a process called phosphorescence. The key to achieving high power output in 405nm LEDs lies in the design and structure of the LED chip. The chip is typically composed of a p-n junction, with the p-type layer doped with indium gallium nitride (InGaN) and the n-type layer doped with gallium nitride (GaN). The InGaN layer serves as the active region, where the light is generated. To enhance the light output, high power 405nm LEDs often employ a technique called surface roughening. This process involves creating micro-structures on the surface of the LED chip, which increases the light extraction efficiency. Additionally, heat dissipation is a critical factor in the performance of high power 405nm LEDs, and thus, thermal management techniques are employed to ensure optimal performance.
