Wavelengths
between 220 nm to 350 nm high-power deep-ultraviolet light-emitting
diodes in the sterilization, water purification, medical care,
high-density optical record, high-color LED lighting and high-speed
decomposition of the material dealing with public nuisance in areas
such as widely used. So far, the deep-ultraviolet light source to
excimer laser and a variety of frequency doubling lasers, and other
gases and solids as a medium of UV laser and gas lamps for the
mainstream, but there are bulky, short life, the shortcomings of high
prices, it is difficult practical application. The use of semiconductor
high-brightness LED deep UV and deep UV LD, can achieve
miniaturization, access to cheap, efficient and long-life UV light
source, application and broader prospects. |
