Description

Fluorescent lamp device to take titanium-layers}

The present invention relates to a fluorescent lamp device coated with a titanium oxide layer, which is a titanium oxide having an extinction function and sterilization / antibacterial function of adhesive oil / inorganic material suspended in the air by visible light and light irradiation in the wavelength range 300nm ~ 400nm ( Titanium oxide layer (5nm-15nm) of TiO2) is dipped (including evaporation) on the luminaire body, translucent cover, and reflector of fluorescent lamps, and is integrally coated by firing treatment under 350 ℃ -600 ℃ for organic / inorganic materials. The present invention provides a fluorescent lamp coated with a titanium oxide layer which ensures durability of a titanium oxide coating layer having a sustained efficiency of adhesion prevention and sterilization / antibacterial. The photocatalytic oxidation of titanium oxide is more than a bandgap energy. When light energy is irradiated to the photocatalyst, electrons and holes are generated, and solid / liquid / gas phase adsorbed on the surface of the photocatalyst by the strong oxidizing power of the radical hydroxide (OH) produced by them It refers to a reaction in which organic matter is decomposed. In other words, oxidative decomposition of environmental pollutants with strong oxidizing power when photocatalytic material is photoexcited, and titanium oxide (TiO 2), zirconium oxide (ZrO 2), arsenic oxide (Sb204), and zinc oxide (ZnO) as derivatives of the photocatalytic reaction. ), Tin oxide (Sn02), cerium oxide (Ce02), tungsten oxide (WO3), iron oxide (Fe203) and the like are known.

Then, photocatalytic coating layers of titanium oxide (TiO2) are oxidized and gradually disappeared by oxidizing an organism (foreign substance) by photocatalysis as a visible and / or ultraviolet wavelength such as sunlight to prevent adhesion of dirty foreign substances on the surface of the photocatalyst coating layer, In addition, after rain on the photocatalytic coating layer, dirty mineral traces are mostly removed by hydrophilic properties induced by photocatalytic activity. Photocatalyst coating layers are known to be stable and resistant as photocatalysts.

Recently, various and visible methods of air purification and pollution prevention using titanium oxide have been proposed. The titanium oxide photocatalyst supporting structure includes a photocatalyst layer, a carrier, and an adhesive layer existing between the photocatalyst layer and the carrier, and the adhesive layer is formed of silicon. It is made of a modified resin, polysiloxane-containing resin or colloidal silica-containing resin, the photocatalyst layer is made of a composite consisting of a metal oxide or hydroxide gel and a photocatalyst, the photocatalyst coating material for forming the structure is a silicon compound, at least one metal oxide Or as a photocatalyst supported structure and photocatalyst coating agent consisting of a metal hydroxide sol, and one or more photocatalyst powders or sols (Patent Publication No. 10-1999-028236).

In recent years, there have been disclosed means for oxidizing / decomposing dirt using a photocatalytic reaction as a means for removing dirt attached to a lighting apparatus. For example, an anitase titanium oxide The photocatalyst-support (including Japanese Patent Application Laid-Open No. 8-246192) containing an oxide layer containing an oxide, and a fluorescent lamp are filled with mercury that emits ultraviolet rays by negative glow discharge in a case having translucency. When a photocatalyst film of titanium dioxide (TiO2), a substance having a photocatalytic action, is formed on the surface thereof, when natural light and an artificial light source (wavelength 410 nm or less) are irradiated, electrons and electron holes (missing holes) are formed in the titanium dioxide (TiO2). Photocatalyst illumination (Japanese Laid-Open Patent Publication No. 1-169866) which oxidizes and decomposes dirt substances attached or contacted to the surface of titanium dioxide (TiO2) by having an oxidizing power on the surface can be seen. In these cases, a photocatalyst film is formed on the inner surface of the light-transmissive cover, but it is unclear whether the deodorizing effect has a sufficient dirt removal effect, and the maximum peak of the light output at a wavelength with low transmittance of the film and the photocatalyst film. Combining light sources with waves may reduce lighting efficiency, such as deterioration of illuminance or adversely affecting the optimization of light distribution, and the problem that the appearance of the lighting device itself may also be impaired.

In addition, a thin layer of silica is formed on the surface of the lamp, and a thin layer of titanium dioxide is formed to express the pollutant. The air pollutant prevention layer coating method (Domestic Patent Publication No. 1999-006999) and the layered fluorescent lamp using a photocatalyst of titanium oxide, which resulted in the luminaire which can improve the environmental effect by the air purification function, Low temperature firing coating of the silicone liquid mixed with neutral water and fluorine resin (PEFT) to protect the coating layer including the existing reflective layer on the reflector plate, which is also read by the luminaire body of the indirect lighting device and the reflector. Dust, oil, smoke, etc. are caused by the photocatalytic action of a silicon (SI02) layer and ultraviolet rays emitted from a wavelength of about 300 nm to 400 nm and general fluorescent lamps. There has also been disclosed a lighting fixture (Domestic Utility Model No. 20-1999-0001036) that constitutes a contaminant prevention layer that integrally forms an acidic titanium (TIO2) layer on which the organic oxide is oxidized and extinguished. .

As described above, the photocatalytic film of various application methods forms a silica (Si02) layer composed mainly of silica (SiO2) as a main component of an anitase crystalline titanium dioxide (TiO2) layer and an intermediate layer thereof. Although the coating forming means of is not easy to prove the demonstration of durability, cold resistance, heat resistance, there is a problem in commercialization.

In view of the above problems, the present invention is a titanium oxide of titanium oxide (TiO2) which performs photocatalytic action (oxidation reaction) by natural light and fluorescent lamp which irradiates visible light and light in the wavelength range of 300nm to 400nm to the fluorescent lamp. The coating layer is integrally formed to prevent cleanliness of organic and inorganic substances suspended in the air by the extinction of organic and inorganic substances by photocatalytic action, and the effect of preventing disease due to sterilization and antibacterial properties, and comfortable indoor air. The present invention provides a fluorescent light fixture coated with a titanium oxide layer, which maintains the anti-glare / antistatic effect of the illuminator.

In order to achieve the object of the present invention, the titanium oxide coating layer of titanium oxide (TiO2), which performs photocatalysis (oxidation reaction), is integrally coated on the luminaire body, the translucent cover, and the reflector constituting the fluorescent lamp, to achieve the desired purpose. The coating method may be carried out by a coating method which is thermally treated after dipping (baking temperature of 350 ° C.-450 ° C.), or another coating method is titanium oxide (presented as crystals in the form of Anatas) by vacuum deposition. The titanium oxide coating layer may be integrally formed by a known vacuum deposition method at a temperature of 500 ° C to 600 ° C.
