In this article, we will delve into the details of high power 405nm LED, including their working principle, advantages, applications, market trends, and future prospects.

Working Principle of High Power 405nm LED

The working principle of high power 405nm LED is based on the photoelectric effect. When an electric current passes through the LED, electrons in the semiconductor material collide with holes, releasing energy in the form of photons. The wavelength of the emitted light is determined by the energy bandgap of the semiconductor material. In the case of 405nm LEDs, the semiconductor material used is typically gallium nitride (GaN), which has an energy bandgap of about 2.4 electron volts (eV). The process of light emission in high power 405nm LED can be divided into three stages: 1. Excitation: When an electric current passes through the LED, electrons and holes are injected into the active region of the semiconductor material. 2. Recombination: Electrons and holes recombine in the active region, releasing energy in the form of photons. 3. Emission: The photons are emitted from the LED, and the light intensity depends on the number of recombination events occurring in the active region.
