Abstract
A LED ultraviolet germicidal lamp includes a bracket, a power box, a driving light source, a heat sink, an ultraviolet light source, a lampshade, a quartz glass, a catalyst gauze, and a lamp frame. The bracket is connected to the heat sink, and the power box and the driving light source are provided in the bracket in sequence from outside to inside. The driving light source is provided in the power box and is connected to the power box by bolts. The heat sink is connected to the power box and is provided at a lower end of the power box. Titanium dioxide is used as the catalyst and is catalyzed by the UVC light source. Hydroxyl radicals produced when nanoscale titanium dioxide catalyst gauze is exposed to the UVC light source destroy bacteria and viruses.
