The human beings have long used the tradition of partial sterilization by using ultraviolet light in sunlight. Ultraviolet ray has been studied by scientific and technical workers at home and abroad for over 200 years, and since the first ultraviolet ray sterilization lamp invented by doctor heishi in germany, the ultraviolet ray sterilization technology is widely applied in more and more fields, in particular to the aspects of air sterilization, object surface sterilization and water treatment sterilization. The scientific principle of ultraviolet disinfection: mainly acts on the DNA of microorganisms to destroy the structure of the DNA, so that the DNA loses the functions of reproduction and self-replication, thereby achieving the aims of sterilization and disinfection. The traditional ultraviolet light source (UV) adopts mercury vapor discharge to generate ultraviolet rays by utilizing the excitation state of mercury, and has the defects of high power consumption, large heat productivity, short service life, slow reaction, potential safety hazard and the like.

The existing disinfection lamp products are mercury lamp quartz lamp tubes, ultraviolet rays and ozone are used for double sterilization, however, the mercury lamp quartz lamp tubes have the risk of mercury toxicity leakage, and are large in light decay and short in service life. After the UV germicidal lamp produced by general manufacturers works for hundreds of hours, the ultraviolet light intensity of the UV germicidal lamp is attenuated quickly, the maximum ultraviolet light intensity reaches 30%, and the germicidal effect is greatly weakened. Since the school classrooms are tight gathering points, disinfection of the classrooms is indispensable. The integrated dual-purpose lamp for the air disinfection and sterilization full-spectrum classroom has come into play in consideration of the fact that the classroom is long in service time and healthy illumination is necessary.

A classroom lamp with disinfection and lighting functions is also known from patent No. CN 110529779. And the ultraviolet light can accelerate the aging of plastics, so the aging and yellowing of the light guide plate can be caused in a short time, the service life is influenced, and the light efficiency and the attractiveness are influenced.
