The titanium apatite component contained in the composite resin bactericidal coating has the effect of specifically adsorbing organic matters and can adsorb the organic matters contacting with the lamp. In use, viruses, bacteria, odor, and the like that come into contact with the lamp body are adsorbed by the titanium apatite, and the photocatalyst (titanium dioxide, titanium apatite) oxidizes and decomposes the adsorbed viruses, bacteria, odor, and the like to purify the surrounding air.
Strong electric energy (potential) electrolysis of nano silver coated on surface of lamp body by plasma discharge of cold cathode fluorescent lamp tubeTo generate silver ions (Ag)+). Silver ion (Ag)+) With the airborne water molecules being free in space. Silver ions diffused into the space can kill harmful bacteria and viruses at a distance. In addition, the generation of silver ions (Ag) was confirmed+) Attached to walls, ceilings, floors, appliances, etc. of the whole facility, has an antibacterial coating effect, and gradually forms a facility environment in which bacteria are difficult to propagate.
The advantages of the invention and the prior art are:
1. the main infection path of the specific virus is aerosol floating in the air, the aerosol repeatedly convects through an air conditioner and continuously collides with the surface of the lamp body, and the surface of the lamp body can adsorb the aerosol and capture the specific virus (the specific virus can be adsorbed in the same way even in a state that the lamp is not turned on). The oxidative decomposition power (1.5 times that of ozone) of the photocatalyst (titanium dioxide, titanium apatite) generated on the surface of the lamp body can decompose a specific virus. A plurality of lamps can adsorb and decompose specific viruses repeatedly for many times, so that aerosol in a space disappears in a short time, and the risk of virus infection is reduced.
2. The lamp can generate silver ions, and can capture negative electrons from specific viruses in the air and attached to walls, ceilings, floors and equipment to inhibit the viruses. Moreover, silver ions can adhere to walls, ceilings, floors and equipment to form silver coatings, which can continuously inhibit the proliferation of bacteria and viruses.
3. The titanium apatite component in the composite resin sterilization coating can adsorb and lock organic matters, so that the re-dispersion of bacteria and viruses is prevented, and the sterilization and disinfection effects are obvious.
4. In addition to the novel viruses, it also acts on viruses that cause seasonal viral infections and food poisoning. Also, as planktonic bacteria decrease, the risk of causing food poisoning decreases. With the reduction of mould spores and pollen, the risk of various allergic reactions caused by the pollen is reduced. By reducing the peculiar smell particles, the room odor is reduced, and the living space is improved.
