Description

Lighting cover of the luminaire that constitutes the pollution prevention layer

The present invention is a silicone liquid in which silicon (SiO ₂ ) is mixed with neutral water and fluorine resin (PEFT) to protect the light-transparent lighting cover of direct and indirect lighting luminaires including lamps, reflecting plates, covers, and struts. Forms a silicon layer with low temperature firing and absorbs organic matters such as dust, oil and smoke suspended in the air by photocatalytic action (oxidation chemical reaction) by ultraviolet rays emitted from sunlight and wavelength of 300nm-400nm on the upper surface. Titanium oxide (TIO ₂ ) layer is integrally formed so that the titanium oxide (TIO ₂ ) particles which are extinguished by oxidation are kept together, thereby keeping the lighting fixtures clean, preventing the fall of illuminance (LUX), and cleaning / repairing of the lighting fixtures. It is also possible to provide lighting covers of lighting fixtures that have a contaminant prevention layer that is beneficial for self cleaning, which can reduce the cost and provide national health and a pleasant living environment through the air purification effect. .

In the past, lighting fixtures are generally classified into luminaires such as HID lamps, fluorescent lamps, sodium lamps, and metal halide lamps, and are classified into living room lamps, street lamps, spotlights, downlights, flower stands, and induction lamps depending on the purpose. We divide into treatments such as tunnels by. In addition, the lighting fixtures are classified into direct lighting (eg fluorescent lamps) in which the lamp light source is direct and indirect lighting reflected by the reflector according to the lighting method.

In addition, there has been disclosed a therapeutic lamp that emits far-infrared rays to give a special function to the general lighting luminaires to obtain an effect outside the lighting, but the luminaire of this special function is coated with a far infrared ceramic (aka bioceramic) on the reflector As the light source wavelength of the radiation lamp promotes the molecular activation of organic materials by the resonance resonance function of radiation radiated from long infrared rays, there was an example of using bacteria propagation suppression function, cold protection function, and metabolic promotion function. It was not desirable to use the lighting cover by causing an adverse effect that lowers the light transmission efficiency of the lighting cover.

In addition, all the lighting devices described above are attached to the luminaire body and the lighting cover that have the reflecting function of the lighting fixtures when they are used for a long period of time, resulting in dirty and poor illumination. As the organic materials such as dust, oil, smoke, bacteria, etc. adhere to the lighting fixtures and harden, the illumination intensity of the lighting drops sharply and the appearance is unsightly, and a cleaning operation is needed to periodically remove contaminants. Since there are many oily substances in the air due to the smoke from the combustor and exhaust gas of the vehicle, the cleaning work of the pollutants attached to the lighting fixtures is not removed by the water cleaning, so there are many cases of using the cleaning agent. There is also an economic problem that is inconvenient and takes much time and money. All.

100: cover 200: silicon layer

300: titanium oxide layer

1 to 3 illustrate an example of a tunnel in various direct lighting devices (fluorescent lamp, spot light, down light, flower stand, induction), and as shown in FIG. Titanium oxide particle layer with active photocatalytic action (reaction) is formed by coating method to prevent pollutants and to purify air.

At this time, the silicon layer 200 of the lighting cover 100 of the lighting fixture is a colorless transparent powder, and the chemically stabilized silicon (SiO ₂ ) is mixed with neutral water and fluorine resin (PEFT) to illuminate The cover 100 layer was coated by spraying or dipping and heated to a baking temperature of 70 ° C. to cure at low temperature, thereby evaporating the organic material and forming a thin film of 0,3 μm-1,0 μm. SiO ₂ ) layer 200 is achieved.

In addition, since the silicon (SiO ₂ ) layer 200 functions as a binder (adhesion) for smoothly bonding the titanium oxide layer 300 thereon, the titanium oxide layer 300 thereon is also uniformly formed.

Further, the low temperature-type titanium oxide of Ana Tasman type (anatas) While silicon layer 200 is to be cured about 50% (TIO ₂₎ is a low temperature-type titanium oxide in the inorganic material of white solid horse Ana Tasman type (anatas) (TIO ₂ ), Ethanol solvent and fluorine resin (PEFT) diluted 10% titanium oxide solution on the silicon layer 200 by spraying and dipping method, and then heated for 10-30 minutes at 100 ℃ -120 ℃ The material is volatilized to form a thin titanium oxide layer 300 having a thickness of 0,3 µm or less.

In the present invention, rutile titanium oxide for high temperature (TIO ₂ ), which is used in the white treatment of paint, paper, etc., is treated by a high thermal firing method of 1000 ° C. or more, and has a photocatalytic effect in ultraviolet rays having a wavelength of 300 nm or less. Unlike brookite-type high temperature titanium oxide ((TIO ₂ ), which is used as a raw material of polymerization catalyst, photocatalytic reaction in ultraviolet light with wavelength of 300nm-400nm emitted from sunlight and fluorescent lamp It is characterized by using anatase-type low-temperature type titanium oxide (TIO ₂ ) in which active oxygen is generated.

Thus, the present invention is to configure the titanium oxide particles to be exposed to the low-temperature Anatas-type titanium oxide layer 300, the ultraviolet light of the wavelength 300nm-400nm band emitted from sunlight, general fluorescence, etc. Since the particles have the same wavelength, the amount of energy of unit photons is the same regardless of the intensity of light. The energy per photon of ultraviolet light in the 300nm-400nm band is about 36,000K and the photocatalytic reaction proceeds continuously. The above phenomenon continues on the surface of the titanium oxide layer 300, and contaminants such as oil, dust, smoke, bacteria, and odors suspended in the air due to convection occur in the titanium oxide layer 300. As soon as the particles come into contact with the particles, they disappear due to oxidation and reduction, so that they float in the air by the photocatalytic action of the titanium oxide layer 300 by the lighting cover 100 of the lighting fixture. The contaminants will be kept clean luminaire without being adhered to the fixture.

In addition, it prevents the fall of the illumination of the light (LUX), reduces the cost of cleaning / repairing the lighting cover, and also provides public health by the sterilization / deodorant function. cleaning effect is obtained.

As described above, the present invention prevents contaminants from sticking to the lighting cover of the lighting fixture, so that the lighting cover is clean, thereby preventing the lowering of the illuminance (LUX) of the lighting, and reducing the illuminance before, and frequently cleaning the lighting fixture due to aesthetic problems. It is economical to reduce inconvenience and cleaning cost.

In addition, the present invention has a high illuminance effect of maintaining bright light due to the diffuse reflection function of the titanium oxide particles.

In addition, the air cleaning effect when oxidizing / extinguishing dust, oil, smoke, bacteria, and odors floating in the air provides a self-cleaning effect that provides a public health and a pleasant living environment.

As described above the date and time of the present invention, the present invention is not limited to this, it will be possible to change within the scope described in the utility model registration request.
