The paper expounds the principle and advantages of disinfection by UV-C radiation
introduces the relative technologies and products at home and abroad
designs elliptic and parabolic cylindroid lampshade of bank paper disinfection apparatus with \!equal path surface\" principle. UV-C radiation can disinfect air
water and solid surface
many kinds of bacteria and virus including SARS. Using elliptic and parabolic cylindroid lampshade
the light energe density of the money disinfection apparatus will be raised
and the disinfection efficiency will be raised greatly.
