High power 405nm LED, also known as a high-intensity blue LED, has emerged as a crucial component in various industries due to its unique spectral properties and high efficiency. This article delves into the world of high power 405nm LED, exploring its applications, technology, market trends, and future prospects.

Introduction to High Power 405nm LED

High power 405nm LED refers to a type of light-emitting diode that emits light at a wavelength of 405 nanometers. These LEDs are designed to produce a higher intensity of light compared to standard LEDs, making them ideal for applications that require concentrated and focused illumination. The high power 405nm LED is often used in conjunction with a phosphor to convert the blue light into white light, as the human eye is more sensitive to blue light, which enhances the perceived brightness.

Technology and Manufacturing

The technology behind high power 405nm LED involves the use of advanced semiconductor materials and fabrication processes. These LEDs are typically made using gallium nitride (GaN) as the active layer, which emits blue light when an electric current is applied. The key to achieving high power output lies in the design of the LED structure, which includes the use of a multi-layer structure to enhance light extraction and improve efficiency. The manufacturing process involves several steps, including epitaxial growth, wafer slicing, and device fabrication. Epitaxial growth is used to create a thin layer of GaN on a substrate, typically sapphire or silicon carbide. The wafer is then sliced into individual dies, which are mounted on a substrate and encapsulated with materials that protect the LED and enhance light extraction.
