IdealPhotonics' ultraviolet LED diodes are solid-state light sources based on group III nitride (such as AlGaN/GaN) material systems. Through bandgap engineering, the emission wavelength (200-400nm) can be controlled, exhibiting bactericidal properties (99.9% pathogen inactivation rate) in the deep ultraviolet band (265-280nm) and high color rendering in the near ultraviolet band (280-400nm). Its innovative "quantum well active region and polarization doping" technology increases the external quantum efficiency to 20%, making it a revolutionary solution for water purification, medical disinfection, and photopolymerization.Employing AlGaN/GaN multiple quantum wells and polarization engineering (Al composition accurate to ±0.5%), this technology achieves a 99.99% sterilization efficiency in the deep ultraviolet (265nm) band and a luminous efficacy of 120 lm/W in the near ultraviolet (365nm) band. Its innovative "nano-patterned substrate" technology boosts the external quantum efficiency to 25%, and its "thermoelectric synergistic heat dissipation" architecture extends its lifespan to over 100,000 hours. This redefines the performance benchmark for ultraviolet light sources in three major fields: medical sterilization (inactivating the novel coronavirus in 0.1 seconds), drinking water purification (removing 6-log pathogens), and industrial photocuring (increasing curing speed by 5 times).
