Achieve UVC LED photoelectric conversion efficiency exceeding 10%

  A company has achieved a technological breakthrough in the evaluation of a new UVC LED. This LED boasts an efficiency exceeding 10% at a power of 200 milliwatts, a wavelength of 265 nanometers, and a lifespan exceeding 20,000 hours. It is expected to replace traditional mercury lamps in future lighting and disinfection applications.

  The company has successfully optimized the efficiency of its UVC LEDs by advancing technological improvements in epitaxial structure, chip, and package design. These LEDs achieve a power-to-photon efficiency (WPE) exceeding 10% while maintaining a long lifespan exceeding 20,000 hours. Compared to previous products with a WPE of approximately 5.3%, this nearly doubles the performance of UVC LEDs without changing other conditions.This peak performance has been verified by the German National Metrology Institute (PTB), whose testing confirmed a WPE of 10.2%. In addition to the improved optical performance, the test samples have also been successfully verified to have a lifespan comparable to currently available high-power LEDs.

  The new UVC LED is expected to be launched by the end of 2026 and will complement the company's existing portfolio of advanced UVC lighting solutions. It is reported that the company currently has more than 200 high-quality patents to safeguard its innovation and intellectual property position in the field of UVC LED technology.
