WHITE LIGHT LAMP FOR PURIFICATION OF ENVIRONMENTAL SANITATION

The present invention relates to a white lighting lamp for environmental hygiene purification, and more particularly, to a white lighting lamp for environmental hygiene purification comprising a near-ultraviolet LED, a near-ultraviolet diffusion and focusing lens, a photocatalyst, and a white light LED for lighting. By activating the photocatalyst by ultraviolet light, air purification, dehumidification, sterilization, deodorization, and antifouling can be effectively performed, and a compact and efficient way to obtain normal white light rather than cold ambient lighting such as black light. It relates to a white light lamp for environmental sanitation and purification.

Nowadays, modern people spend most of their time indoors, so interest in pleasant and healthy indoor environmental hygiene is very high.

In recent years, residential and commercial buildings are built in a structure that emphasizes insulation and airtightness in order to increase heating and cooling efficiency, so ventilation for indoor air purification and introduction of fresh air is important.

These indoor environmental hygiene problems include adhesives and preservatives used in building interior materials, mites and bacteria such as sofas and carpets, house dust mites, volatile organic compounds used in cleaning agents, bleach and air fresheners used in bathrooms, and cooking appliances such as gas ranges. Carbon monoxide, various nitrogen compounds, cigarette smoke, and fine dust that is getting worse from carbon monoxide are emerging as a very important problem.

Natural ventilation, which purifies indoor air by opening windows, is the most basic and important task, but on days when the air pollution is severe or the concentration of fine dust from China caused by the westerlies is high, this is not easy. Modern buildings adopt centralized air conditioning systems, and the use of mobile or stationary air conditioning systems is increasing in residential or office buildings that do not.

Most of the general centralized air conditioning systems or air conditioners use scrubbers, pre-filters, carbon filters, non-woven filters, and dust collectors in arbitrary combinations to remove contaminants such as fine dust particles, odor components, and bacteria present in the air. It is collected and removed, but HEPA (High Efficiency Particulate Air Filter) and ULPA (ULPA) filter cause overload, so it is not widely applied except for biotechnology facilities such as semiconductor fabs and operating rooms. .

Since filters are used in these central air conditioning systems or air conditioners, replacement or cleaning of the filters is required. There is a risk of spreading by putting it in the air.

On the other hand, there is a problem that it is not practically possible to use such a central air conditioning system or air conditioner in wastewater treatment facilities, pigs, pens, or poultry houses, which are odor-causing facilities. It affects the immunity, reproduction rate, growth rate, meat quality, and mortality rate of cattle or chickens, and there is a problem that it is not easy to solve it even though it causes civil complaints from neighboring private houses.

Recently, a method of sterilizing, deodorizing, and antifouling by activating a photocatalyst by irradiating ultraviolet rays has been proposed.

The photocatalyst reaction activates the photocatalyst by irradiating ultraviolet rays on the surface of the photocatalyst to decompose and denaturate various pollutants and bacteria, decomposes organic or inorganic substances to remove odors, and is independent of temperature and concentration of pollutants. .

Photocatalyst absorbs ultraviolet light and generates electrons and holes, the electrons and holes is very holds a strong reducing power and oxidizing power, in particular electrons second oxide anion by reaction with oxygen (O ₂ ^-) generated for the hole is water OH radicals are produced by reaction with

Ultraviolet rays used for photocatalyst excitation are generally near-ultraviolet (290-400 nm), and commercially available near-ultraviolet LEDs of 360 nm and 380 nm are commercially available. It is widely used in the manufacture of white light LEDs because it is high and similar to natural light.

In general, the photocatalyst that accelerates the photoreaction accelerates the reaction rate by providing a mechanism path different from the existing photoreaction without directly participating in the reaction, and TiO as a material for inducing the photocatalytic reaction₂, ZnO, CdS, V₂O₃, GaP, InP, GaAs, BaTiO₃, KNbO₃, Fe₂O₃, Ta₂O₃, WO₃, SnO₂, Bi₂O₃, NiO, Cu₂O, SiO, SiO₂, MoS₂, InPb, RuO₂, CeO₂, SrTiO, a perovskite-type composite metal oxide₃ and the like, and metals such as Pt, Rh, Ag, Cu, Sn, Ni, Fe, and metal oxides thereof are added to the photocatalyst.

Among them, titanium dioxide (TiO ₂ ) is harmless to the human body, has excellent photocatalytic activity, excellent chemical resistance and light corrosion resistance, good adhesion to coating, and is most widely used due to its eco-friendliness and economical efficiency.

The following are mentioned as conventional typical techniques using such ultraviolet rays and a photocatalyst.
