Introduction to High Power 405nm UV LED

High power 405nm UV LEDs are a type of light-emitting diode that operates at a specific ultraviolet wavelength. The "high power" designation refers to the LED's ability to emit a significant amount of light at the 405nm wavelength. Unlike traditional UV LEDs, which typically have lower power outputs, high power 405nm UV LEDs can provide up to several watts of output, making them more suitable for high-intensity applications. The 405nm wavelength is in the near-ultraviolet region of the electromagnetic spectrum. This specific wavelength is particularly useful because it corresponds to the maximum absorption peak of many photopolymers used in curing applications. As a result, high power 405nm UV LEDs are highly efficient in curing processes, which is one of their primary applications.

How High Power 405nm UV LED Works

The working principle of a high power 405nm UV LED is similar to that of other LEDs. It consists of a semiconductor material, typically gallium nitride (GaN), that emits light when an electric current is applied. The semiconductor is sandwiched between two electrodes, and when a voltage is applied across the electrodes, electrons and holes recombine, releasing energy in the form of light. The key to producing high power 405nm UV LEDs lies in the design and optimization of the semiconductor structure. High-quality GaN materials, advanced epitaxial growth techniques, and efficient heat dissipation are crucial factors in achieving high power outputs. Additionally, the use of optical cavity structures can enhance the extraction efficiency of the emitted light, further increasing the LED's power.
