1 is an exemplary view showing a configuration according to the invention, Figures 2 to 5 is an exemplary view showing a luminaire having a reflective layer according to the present invention, Figure 6 is an exemplary view showing a luminaire to which the present invention is applied. 7 shows an exemplary view showing a luminaire and a street lamp to which the present invention is applied, and the present invention provides a luminaire 20 such as a fluorescent lamp, a lamp, a street lamp, a halogen lamp, etc. having a reflective layer 10 for light reflection efficiency. );

The reflective layer is 10-50 wt% polyester resin, 10-50 wt% epoxy resin, 0.5-1.5 wt% pinhole inhibitor, 0.5-1.5 wt% smoothing additive, tourmaline 2-6 wt%, isothiazoline compound 2-6 wt%, It is coated with a self-made material composed of 10 to 50 wt% of titanium dioxide.

The reflective layer 10 is one side of the luminaire 20, that is, inside / outside the luminaire case 30, fluorescent lamps, halogen lamps, light bulbs, LEDs, etc., the cover 40 coupled to the luminaire case, fluorescent lamps The self-cleaning material is coated to a certain thickness on the surface of the panel serving as a reflector of the lighting device, such as a reflective panel installed inside, a reflective panel 70 of a street lamp, a cover of a lamp 80, and the like, and efficiently reflects light. Increasing the illuminance of the instrument and carrying out its own purification function.

The polyester resin is added as a binder to enhance light reflectance and mechanical strength, and is preferably a saturated polyester resin having a high visible light transmittance.

The epoxy resin is added as a curing agent for improving the mechanical properties of the coated coating film, and is preferably a bisphenol A epoxy resin or triglycidyl isocyanurate. When the content of the epoxy resin is out of the above range, there is a fear that the coating film becomes too soft or cracked.

The tourmaline has the only permanent electrical properties among the minerals present on the earth, the chemical composition is composed of complex borosilicates of iron, magnesium, alkali metals and aluminum. Such tourmaline has the effect of purifying air, purifying water, removing odor, promoting metabolism, etc., by anion and far-infrared effect generated by antioxidant action and small current of 0.06A.

In addition, the tourmaline is prepared in nano form and coated with a particle size similar to that of the powder coating to maintain the tourmaline properties to minimize the influence on the reflectance.

The isothiazoline-based compound is for imparting antibacterial function, 2-methyl-4-isothiazoline-3-non, 4,5-dichloro-2-n-octyl-4-isothiazoli-3- Non- (DCOIT), 2-n-octyl-isothiazol-3-non (OIT) is used alone or in combination of one or more, preferably 4,5-dichloro-2-n-octyl-4- An isothiazoline-based compound obtained by mixing isothiazolin-3-non (DCOIT) and 2-n-octyl-isothiazolin-3-non (OIT) in a weight ratio of about 2 to 4: 1 is used. This weight ratio is characterized by the sterilizing action of 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) and 2-n-octyl-isothiazolin-3-one ( OIT) is a long lasting antimicrobial action by mixing the action.

The smoothing additive is to prevent the diffuse reflection and to increase the reflectance, the general powder paint is difficult to form a smooth surface because the particles are non-uniform, the non-uniform surface causes the diffuse reflection, select any one or more of the smoothing additive It may be included, preferably an acrylic leveling additive, and more preferably comprises a silica career acrylic copolymer (silica career acrylic copolymer). At this time, the content of the smoothing additive is preferably in the above range to maintain the most effective reflectance.

Since the pinhole inhibitor may be selected from one or more known pinhole inhibitors, it is not particularly limited in the present invention. However, in order to exhibit the excellent bubble prevention property, it is preferable that it is benzoin.

The titanium dioxide has a pigment and a photocatalyst function, and also improves the reflectance by preventing pinholes and the like formed on the surface of the coating film.

The titanium dioxide preferably satisfies the content range for implementing the photocatalytic effect and high reflectivity of the reflective layer. In addition, when the spreadability of the coating film is lowered in the process of applying the self-cleaning material, the surface may not be kept constant and may diffusely reflect light. Therefore, in order to improve the spreadability of the coating film, the curing rate of the paint can be adjusted by appropriately adjusting the synthesis ratio of the titanium dioxide and the synthetic resin.

Such titanium dioxide may act as a photocatalyst to exhibit the effects of decomposition of volatile compounds and bacterial inhibition. Fine titanium dioxide particles generate free radicals by ultraviolet rays (380 nm) contained in sunlight or fluorescent light. Active oxygen generated at this time exhibits a strong redox effect, resulting in organic decomposition, sterilization, antifouling action, hydrophilicity, and the like.

The titanium dioxide is used by using anatase-type titanium dioxide nanopowder, or by mixing anatase-type nanopowder and rutile type titanium dioxide powder in a weight ratio of 1: 1 to 2.

In the case of titanium dioxide, when the gap (gab) of the energy band is 3.2 eV and absorbs more energy by ultraviolet rays, electrons in the valence band move to the conduction band. In this case, holes are made in the valence band, and the electrons and holes are moved to the surface, respectively, to combine with oxygen and moisture to generate radicals, that is, active oxygen.

Hereinafter, the photocatalytic action mechanism of titanium dioxide will be described.

1) When UV is irradiated on the photocatalyst, electrons and holes are generated.

2) Oxygen and electrons in the air layer react to generate active oxygen.

3) Moisture and holes in the air layer react to produce hydroxyl radicals.

4) Free radicals and hydroxyl radicals show strong organic decomposition.

In the case of such titanium dioxide, the oxidizing power of the hole is more powerful, and mainly hydroxyl radicals oxidize organic substances and decompose them into carbon dioxide and water. In addition, it exhibits antimicrobial activity even in weak ultraviolet light that does not kill bacteria. It also has the effect of killing bacteria and viruses such as E. coli, O-157, Staphylococcus aureus, MRSA, and other organic substances such as nitrogen oxides and sulfur oxides in the atmosphere. It ionizes, decomposes formaldehyde, and decomposes tobacco smell, food smell, ammonia smell, and the like.

Other additives may further include additives such as a plasticizer, a plasticizer, a desiccant, or a dispersant for maximizing the surface roughness and gloss by maximizing the reflectance of the coating film, in addition to the above components, and the selection and content of the additive may be a general method. You can adjust it accordingly without difficulty. That is, the other additives do not significantly affect the physical properties, so each of these components and the mixing ratio is added to adjust appropriately according to the purpose.

Reflective paint of the present invention made as described above is a powder-type paint that does not contain a solvent, there is no risk of poisoning or fire by the solvent, it is possible to reduce the pollution problems such as air pollution or water pollution. In addition, it is unnecessary to adjust the viscosity, and coating is easy because the coating film having a sufficient thickness can be formed by one coating, and the coating film formed therefrom exhibits a visible light reflectance of 90% or more.

Hereinafter, a manufacturing method of a lighting device according to the present invention will be described.

In the spray coating step, 50 to 80 KV electrostatic spray coating is performed on the formed self-adhesive material to the inside of the cover of the luminaire or the reflecting plate to form a reflective layer. In this case, the reflective layer is formed to 70 ~ 140㎛. The thickness of the radiation layer is considered at the same time reflectance, coating film strength and durability.

That is, the reflective layer has a thickness of 70 to 140 µm to maintain a reflectance of 93% or more and a luminaire efficiency of 90% or more, as defined by the Energy Management Corporation, to strengthen the coating film, and to increase the strength to prevent cracking, thereby improving durability. .

In addition, since the thickness of the reflective layer as described above can be formed by one application of the self-cleaning material, the painting is easy. In addition, the self-cleaning material of the present invention can be significantly improved in the working environment because there is no volatile content, the coating work is easy because the viscosity adjustment is unnecessary.

The first drying step is to form a reflective layer by first drying the applied self-cleaning material, it is preferable to dry for about 15 minutes in the range of about 180 ℃.
