For example, in the domestic bathroom, because of the humidity, the air is not circulated, the smell is odorous, the corners such as hair and sanitary ware will breed a large number of bacteria, which seriously endanger people's health. The number of deaths caused by indoor air pollution in our country exceeds 110,000 per year, and the number of emergency medical treatments reaches 4.3 million, resulting in direct or indirect economic losses of more than $10.7 billion.

As more and more people begin to pay attention to the conditions of the living environment, especially the indoor air quality problems in the living environment. A wide variety of sterilizing lamps have emerged. However, most of the existing sterilizing lamps are pure ultraviolet lamps or negative ion air purification lamps. The shortcomings of these structures are as follows: 1. While disinfecting and sterilizing, it has damage to the human body, so it cannot directly replace the existing lighting fixtures; 2. The time of disinfection and sterilization is artificially controlled, sometimes it wastes energy. Moreover, the service life of the lamp tube is shortened and the use cost is increased; Third, it can be used only in a special place where sterilization and sterilization are required, and generally cannot be used in a home interior, so the limitation of use is large.
