PURIFYING LAMP FOR ENVIRONMENTAL SANITATION COMPRISING THE LED ASSEMBLY FOR BLACK LIGHT BLUE LAMP

The present invention relates to a lamp for environmental sanitation purification including an LED assembly for a black light blue lamp, and more particularly, a photocatalyst is coated on the outer surface to purify air, dehumidify, sterilize, and deodorize by activation of the photocatalyst by near UV rays And, because it can effectively perform anti-fouling action, it can be effectively applied to homes, offices, hospitals, fitness centers, wastewater treatment facilities that are odor-causing facilities, pig houses, barns, or chicken houses, etc. It relates to a lamp for environmental hygiene purification including an LED assembly for the lamp.

Recently, interest in pleasant and healthy indoor environmental hygiene is on the rise due to the improvement of living standards and rising interest in health, but in reality, adhesives and preservatives used in building interior materials, fungi and bacteria such as sofas and carpets, and house dust It is seriously threatened by mites, volatile organic compounds used in cleaning agents, bleach, and fragrances used in bathrooms, carbon monoxide and various nitrogen compounds from cooking appliances such as gas ranges, cigarette smoke, and fine dust that is getting worse.

In addition, the environmental hygiene of pigs, cows, or chickens, which are odor-causing facilities, affects the immunity, reproduction rate, growth rate, meat quality, and mortality rate of pigs, cattle, or chickens, and it is difficult to solve the problem even though it causes civil complaints from nearby private houses. have.

In order to solve this problem, recently, a method of sterilizing, deodorizing, and antifouling by activating a photocatalyst by irradiating ultraviolet rays has been proposed.

The photocatalyst reaction decomposes and denatures various pollutants and bacteria by activating the photocatalyst by irradiating ultraviolet rays on the photocatalyst surface, as well as decomposing organic or inorganic substances to remove odors, so it is independent of temperature and pollutant concentration. .

The photocatalyst absorbs ultraviolet rays and generates electrons and holes with very strong reducing and oxidizing power. In particular, electrons generate superoxide anions (O ₂ ⁻ ) by reaction with oxygen, and holes produce OH radicals by reaction with water. create

The ultraviolet light used for excitation of the photocatalyst is generally near ultraviolet (290~400 nm), and as a photocatalyst, TiO ₂ , ZnO, CdS, V ₂ O ₃ , GaP, InP, GaAs, BaTiO ₃ , KNbO ₃ , Fe ₂ O ₃ , Ta ₂ O ₃ , WO ₃ , SnO ₂ , Bi ₂ O ₃ , NiO, Cu ₂ O, SiO, SiO ₂ , MoS ₂ , InPb, RuO ₂ , CeO ₂ , SrTiO, a perovskite-type composite metal oxide ₃ 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, has excellent chemical and light corrosion resistance, good adhesion to coating, and is environmentally friendly and economical, so it is the most widely used.

On the other hand, as the ultraviolet irradiation means, a black light blue lamp or a near-ultraviolet LED of 360 nm or 380 nm is used.

Here, the black light blue lamp is a cobalt glass tube that blocks visible light but transmits ultraviolet light while blocking visible light from a phosphor such as calcium phosphate activated with selenium or the like that emits near-ultraviolet rays by excitation of 2537 Å of a spectral line of mercury emitted from a low-pressure mercury lamp.
