Description

Control system and control method of illumination apparatus integrated with ultraviolet disinfection module
Technical Field
The invention relates to the technical field of lighting fixtures, in particular to a control system and a control method of a lighting fixture integrated with an ultraviolet disinfection module.
Background
Ultraviolet disinfection and sterilization is to destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms by ultraviolet irradiation, so that bacteria die or can not reproduce offspring immediately, and the aim of disinfection and sterilization is achieved. The ultraviolet rays with the sterilizing effect are UVC ultraviolet rays with the wavelength of 280nm or less, and the ultraviolet rays with the wavelength of 254nm are particularly optimal because the ultraviolet rays with the wavelength of 280nm are easily absorbed by DNA of organisms. While 185nm ultraviolet rays are easy to generate ozone, although the disinfection and sterilization are good, the ozone is harmful to people, the ozone function is not recommended to be used in places with dense crowds, and if the ozone is adopted, the ventilation time is not less than 30 minutes.
The sterilization effect of ultraviolet rays depends on the dosage of ultraviolet rays, and is affected by the type, intensity and use time of the ultraviolet rays. The ultraviolet irradiation dose means that a specific wavelength of ultraviolet irradiation dose is required to achieve a certain bacterial inactivation rate.
The ultraviolet irradiation dose formula is as follows:
irradiation dose (mJ/c 2, millijoules per square centimeter) =irradiation time (s, seconds) ×uvc intensity (μw/cm) 2 Microwatts per square centimeter
The larger the irradiation dose is, the higher the disinfection and sterilization efficiency is, and if the fast and efficient sterilization is required, the output intensity of UVC ultraviolet rays becomes a main parameter for measuring the disinfection and sterilization effect.
The ultraviolet disinfection time and the dosage are different according to the different microorganism types. The peak of ultraviolet absorption varies from one bacterial species to another.
Table 1: radiation dose necessary for killing various microorganisms and viruses
In the condition of sufficient ultraviolet dose, the inactivated virus and bacteria cannot be revived, but in the condition of insufficient ultraviolet dose, many virus and bacteria inactivated by ultraviolet irradiation can repair the damaged structure by the assistance of light. When the ultraviolet dose is the same, the irradiation mode with high intensity, short time or low intensity and long time can be adopted to achieve the aim of disinfection and sterilization.
The intensity of ultraviolet disinfection is related to the irradiation area and irradiation distance, and the closer the distance is, the higher the intensity is; the farther the distance, the lower the intensity. The higher the intensity of the ultraviolet light, the faster the bacteria can be killed. Taking a 40W light pipe bracket ultraviolet disinfection lamp of a certain brand as an example, the ultraviolet illuminance is 228 mu W/cm at a distance of 1 meter from the lamp tube 2 Only 10 seconds is needed to reach 2280mJ/cm 2 Is used for sterilizing irradiation dose. Considering the influence of different factors in practical application, such as air damage, surface cleanliness, difference of ultraviolet resistance of different germs, and the like, high-intensity ultraviolet rays are generally used in practical application to ensure disinfection and sterilization effects.
Table 2: the radiation dose of various microorganisms and viruses is 30 mu W/cm 2 Time to inactivate
The ultraviolet disinfection belongs to a pure physical disinfection method, has the advantages of simplicity, convenience, broad spectrum, high efficiency, no secondary pollution, convenient management, automation realization and the like, and along with the push of ultraviolet light sources of various novel designs, the application range of ultraviolet disinfection is also expanding continuously.
The transmission route of infectious bacteria and viruses is usually mainly air transmission. Most closed or semi-closed rooms of residential and office environments rely on convection by air conditioning or fresh air systems, which have internal circulation characteristics that allow air to flow through the bottom and upper portions of the space. If the ultraviolet disinfection module is arranged in the upper area of the indoor space, the ultraviolet irradiation disinfection is carried out on the air, thus being beneficial to reducing the risk of cross infection of indoor bacteria and viruses. The daily lighting lamp is generally arranged in the upper region of the indoor space, and if an integrated device of the ultraviolet disinfection module and the lighting device is arranged, the daily lighting lamp is greatly convenient for consumers.
The ultraviolet lamp tube for irradiation disinfection has the defects that the scattering range is larger, the ultraviolet lamp tube is extremely easy to irradiate the moving area of a person, and meanwhile, ozone hazard is also generated, so that a certain risk exists during use. Therefore, people have to avoid the coexistence of people and machines when sterilizing, and the practicability of air sterilization is reduced.
Accordingly, there is a need for improvements in the art to avoid the disadvantages of the prior art.
