2. the ultraviolet ray responds to the photocatalyst to kill the lamp. The ultraviolet light source is used for triggering the photocatalyst to complete disinfection and sterilization, and in the mode, because the ultraviolet rays indirectly realize disinfection, people can coexist in the same environment when the lamp works in the disinfection process as long as the product has measures for preventing the ultraviolet rays from entering the environment through the light-emitting surface; but the requirements of illumination and energy conservation are considered, and the efficiency of the lamp is lower than that of a common visible light lamp for illumination;
