. Operating Principle

This is a semiconductor light source. When a forward voltage is applied across the p-n junction, electrons and holes are injected into the active region. Their recombination releases energy in the form of photons. The specific wavelength of these photons (in the UVC range) is determined by the bandgap energy of the semiconductor material used, typically aluminum gallium nitride (AlGaN) with a high aluminum content for shorter wavelengths.

. Technology Trends

The UV LED market, particularly for UVC applications, is focused on increasing wall-plug efficiency (optical power out / electrical power in), which historically has been lower than for visible LEDs. Improvements in epitaxial growth, light extraction techniques, and packaging are steadily driving higher output power and longer lifetimes while reducing cost per milliwatt. This enables the expansion of UV LED technology from niche applications into broader consumer and industrial markets for disinfection and sensing.
