1) AlGaN high WPE, low voltage, long life epitaxial process 

2) More UV LED wavelength options (225nm-405nm, any 5nm demand can be met) 

3) Different chip sizes, optimal luminous efficacy (10 mil, 15 mil, 20 mil, 22 mil, 30 mil, 40 mil, 45 mil, 48 mil) 4) Every quarter, the WPE (photoelectric conversion efficiency) continues to improve. 48mil) 

4) Continuous improvement of WPE (photoelectric conversion efficiency) every quarter.  So far, the highest WPE = 6.4% (275nm 350mA 130mW 5.8V) high endurance chips, chips can be directly in the high temperature and high humidity (85 degrees 85 humidity) in the harsh environment.
