Description

A kind of sterilization and mosquito killing air purification LED lamp and control method

technical field

The invention relates to the technical field of LED indoor lighting lamps, in particular to a sterilization, mosquito-killing, air-purifying LED lamp and a control method.

Background technique

LED indoor lighting fixtures are often used for lighting in classrooms, hospitals, offices, workshops and other indoor places. They can be embedded in the ceiling, or suspended under the ceiling or fixed on the ceiling or wall surface, usually for a single lighting function.

Ultraviolet germicidal lamps can emit high-dose ultraviolet rays in a specific band, destroy the DNA or RNA of microorganisms such as bacteria and viruses, and then kill cells, and play a role in sterilization and disinfection. They are widely used in hospitals, schools, nurseries, cinemas, buses, etc. Disinfection and sterilization in offices and other places. However, when the existing ultraviolet lamp is sterilized, due to the photochemical reaction with oxygen and its own characteristics, the irradiance of the ultraviolet lamp will be greatly attenuated with the increase of the irradiation distance. Generally, the sterilization distance is within 1m, and the radiation dose and power consumption is high. At the same time, high doses of ultraviolet rays will also kill the cells of the human body. Therefore, when using ultraviolet lamps for disinfection, it cannot directly irradiate human skin and eyes. When disinfection, people need to leave, and real-time disinfection cannot be performed in spaces where people are active. Coronavirus, etc., viruses and bacterial microorganisms spread in the air through "aerosols", in densely crowded places, the real-time uninterrupted large-scale disinfection and purification of the air can greatly reduce the risk of virus and bacteria transmission. Significant.

Air purifier, air purifier is mainly composed of motor, fan, air filter and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine. It can remove or adsorb various pollutants to achieve the purpose of cleaning and purifying the air. Usually air purifiers are placed on the ground, but air purifiers used in kindergartens and classrooms can be touched by children. Due to the curiosity of young children and lack of awareness of danger, there are certain safety hazards.

In the Chinese patent application number 201611100454.1, the patent document with the publication date of 2018.06.15 discloses a sterilization and mosquito repellent LED lighting fixture, including a lampshade, a base, an LED lamp socket and a heat dissipation pipe, and the connection between the base and the bottom plate They are fixedly connected by a support column, the surface of the support column is inlaid with a control panel, the lampshade and the bottom plate are fixedly connected by a lampshade support rod, the LED lamp socket is installed on the upper surface of the bottom plate, and the electric mosquito coil body It consists of an electric mosquito coil mounting plate, an outer casing, an electric heating wire and an air diffuser.
