Filter-free air purification lamp {FILTER-FREE AIR PURIFYING LAMP}

The present invention relates to a filter-free air purifying lamp, and more particularly, by changing the structure of only the socket cover of the black light blue lamp and allowing the LED lamp assembly to be simply and easily mounted thereto, which has a long lifespan. When the lifespan of the black light blue lamp, which has a relatively short lifespan compared to the LED lamp, is reached, only the black light blue bulb (fluorescent tube) needs to be replaced, so it is highly economical, and the LED lamp assembly and the black light blue lamp are independent of each other. Since it has a configuration, there is no need for a separate additional electrical configuration for merging them, so it has high usability. By activating the photocatalyst by It relates to a filter-free air purifying lamp that can be effectively applied to livestock houses, and can optionally be applied as an indoor decoration lamp that expresses high emotional quality by applying LED that irradiates light of various colors in addition to UV LED.

The indoor living environment, where people spend most of their time in modern life, where they pursue a happy life through the harmony of physical and mental health, is an adhesive or preservative used in building interior materials, fungi and bacteria such as sofas and carpets, house dust mites, bathrooms, etc. It is easy to deteriorate due to volatile organic compounds used in cleaning agents, bleach, air fresheners, etc., carbon monoxide, various nitrogen compounds, and cigarette smoke from cooking appliances such as gas ranges. is not the reality.

In addition, as modern life tends to emphasize individuality and sensibility, the demand for interior decorations of various shapes and colors is also increasing.

On the other hand, 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. not.

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

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. This photocatalyst reaction decomposes and denatures various pollutants and bacteria, and also decomposes organic or inorganic substances to remove odors, so it is independent of temperature and concentration of pollutants.

Ultraviolet rays used for excitation of photocatalysts are generally near ultraviolet (290~400nm), and as photocatalysts, 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, in which 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 315 nm to 420 nm is used. It is a lamp coated on the inner wall of a cobalt glass tube that blocks visible light but transmits ultraviolet light through a phosphor such as calcium phosphate activated with selenium.

The following can be mentioned as conventional typical techniques for lamps using such ultraviolet rays and photocatalysts.
