The present invention relates to a luminaire and a lamp including a bead, and more particularly, to prevent the adhesion of dust or contaminants to the light emitting and reflecting surfaces of the light and the luminaire, and even once attached, can easily remove the attachment. In addition, the present invention relates to a luminaire and a lamp including beads which are easy to construct and which can improve physical properties such as weather resistance, stain resistance, scratch resistance, chemical resistance, impact resistance, and the like of a coated surface.

In general, luminaires and lamps, especially fluorescent lamps, are adsorbed or attached to various dusts and dusts due to static electricity or exposure to the outside for a long time, thereby damaging aesthetics and reducing luminous efficiency. As a result, huge budgets and manpower have been invested to remove dust or adsorbate and have been cleaned at regular intervals.

However, dust attached to lamps and luminaires has a narrow gap between luminaires and lamps, and is located on the ceiling, which makes them difficult to clean. Furthermore, dirt and damage to aesthetics and lamps are seriously impaired because they are not removed. It is a situation that raises and lowers the illuminance of the office environment.

Accordingly, various methods have been tried to prevent adhesion of dust, dust, or contaminants, but there are no effective prevention measures.

In order to solve the problems of the prior art as described above, the present invention can provide a light and luminaire that can not only prevent the adhesion of dust or dirt to the reflective surface of the light and luminaire, but also easily remove it even once attached. The purpose.

It is another object of the present invention to provide a lamp and a lamp which can be easily constructed and can improve physical properties such as weather resistance, stain resistance, scratch resistance, chemical resistance, impact resistance, etc. of the coated surface to be coated.

In order to achieve the above object, the present invention

A luminaire structure with a reflecting surface against an electric light;

A resin binder layer made of a resin binder applied to all or part of the luminaire structure reflecting surface; And

Provided is a luminaire comprising a bead comprising a bead layer consisting of a plurality of beads are bonded to the surface of the resin binder layer and protruded to the outside.

In addition, the present invention

An outermost structure of a lamp including a light emitting unit;

A resin binder layer made of a resin binder applied to all or part of the structure; And

It provides a lamp comprising a bead comprising a bead layer consisting of a plurality of beads that are bonded to the surface of the resin binder layer and protruded to the outside.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A luminaire comprising a bead of the present invention is coupled to a surface of the resin binder layer and a resin binder layer made of a resin binder applied to a luminaire structure, all or a portion of the luminaire structure reflection surface with respect to the lamp; It comprises a bead layer consisting of a plurality of beads which are bulge outwardly.

The luminaire includes various luminaires having a known reflection surface, and is particularly preferable in the case of a fluorescent lamp for which the reflection surface is exposed to the outside because it is excellent in preventing dust adhesion. Specific examples thereof may include a luminaire frame including a fluorescent lamp fixed to the ceiling of a general office, and the surface on which the bead layer is formed refers to a surface configured to reflect a fluorescent light.

In addition, the lamp including the bead of the present invention is coupled to the surface of the outermost structure of the lamp including the light emitting portion, a resin binder layer consisting of a resin binder applied to all or part of the structure and the coated resin binder layer It comprises a bead layer consisting of a plurality of beads which are bulge outwardly.

The lamp includes various types of lights known in the art, and the outermost surface is generally the outer surface of the glass part of the lamp. The lamp includes an incandescent lamp or a fluorescent lamp, and is preferable because the effect is great in the case of fluorescent lamps that generate a lot of static electricity by emitting light upon discharge.

The resin binder used in the luminaire and the lamp including the bead of the present invention is a component that acts as a binder can be used mainly resins for exterior or interior use, in particular acrylic resin, ceramic resin, fluorine or urethane resin It is good to use resin selected from the group which consists of 1 or more types.

The acrylic resin may be a solvent-type acrylic urethane, an aqueous acrylic hydrosol, an emulsion-free solvent-based acrylic silane, or an ultraviolet curable acryl based on methacrylic acid or an acrylic acid derivative.

The urethane-based resin can be used as a general urethane-based resin used in the art, and, for example, generally prepared from organic polyisocyanates and organic compounds containing active hydrogen atoms found in the hydroxyl and amino moieties. There is a known thermosetting resin.

The ceramic resin may be a silicate ester, a hydrolysis product thereof, a water dispersion silica sol, an alcohol dispersion silica sol, or the like.

In particular, when applied to a fluorescent lamp and a luminaire using the same, it is preferable to use a known fluorine-based resin that can prevent it in order to prevent degradation and discoloration due to ultraviolet rays.

In addition, the resin binder preferably has a viscosity in the range of 10,000 to 200,000 cPs, more preferably around 150,000 cPs for ease of application. In addition, various methods known in the art may be applied as the method of applying the resin binder layer, and specific examples thereof may include methods such as painting with a brush, spraying, and dipping.

The resin binder as described above is applied to the surface of the structure, and is cured by spraying and attaching beads on top of the resin binder before the resin binder is cured.

In addition, as the curing method of the resin binder, a variety of known curing methods may be applied thereto. Particularly, the curing method may include natural drying, baking drying, cooling solidification, catalytic curing, ultraviolet curing, and electron beam curing, depending on the type of resin binder (paint). One or more selected from the group can be selected and applied, and this can be applied in various configurations depending on the type of resin binder selected according to the appropriateness of each application and construction method.

The beads used in the present invention may be a spherical shape, an oval shape, or any shape similar thereto. Preferably, the spherical beads are formed in a spherical shape by depositing a bead protrusion on an upper portion of the resin binder. It serves to reduce the contact surface between the surface and the adhesive. In addition, when air enters the unevenness between the bead protrusions formed on the resin binder, the air spreads to the upper part of the bead, forming an air film, thereby lowering the surface tension of the object, thereby preventing adhesion or adhesion of adhesives such as dust and contaminants. It acts to prevent it.

After the beads are sprayed and cured on the resin binder, the beads may be fixed by the resin binder and protrude from the resin binder to form protrusions.

Various known transparent, translucent, or opaque colorless or colored beads may be used in the form of the beads. Preferably, the beads may be transparent beads, and may be ceramic beads, metal beads, resin beads, Various known beads such as glass beads, PMMA beads, zirconia beads or mixtures thereof can be used, and preferably glass beads, PMMA beads, zirconia beads or mixtures thereof can be used. This can increase the strength and anti-sticking properties. More preferably, the glass beads are preferably used in consideration of the strength and discoloration of the bead layer, prevention of discoloration, electrostatic properties with the resin binder, and the like.

In particular, the glass beads are obtained by treating glass powder obtained by pulverizing glass, cullet, glass fiber, or glass curet, and the like. The glass composition is compatible with resin binders such as A, C, E, and alkali-resistant glass powder compositions. If it exists, it is not specifically limited.

The glass beads may be spherical, elliptical, or glass beads of any shape equivalent thereto, and may be used, from those in which various sizes are distributed to those of only a predetermined size.

The particle diameter of the bead may be appropriately selected and used according to the material, use, and the like of the post of the roadbed facility in which the attachment preventing body of the present invention is formed, the wall of a building or a structure, and preferably 1 nm to 1 mm. Preferably, it is more preferable that it is 0.05-0.1 micrometer. They can also exhibit a variety of shapes and properties by the combination of beads having a small particle size of several μm and a large particle size of several tens of μm. However, if the particle diameter of the bead exceeds 1 mm, the contact surface of the adherend and the adhesive is increased, there is a problem that the dispersibility may be lowered and the reflecting surface is uneven.

Beads as described above can be used by adjusting the appropriate amount according to the anti-adhesion, adhered surface required, and particularly preferably contained in 50 to 150 parts by weight based on 100 parts by weight of the resin binder solids, more preferably 70 to It is included in 90 parts by weight. If the content is less than 50 parts by weight, the amount is too small to prevent the adhesion of dust is insignificant. If the content is more than 150 parts by weight, the content is relatively high compared to the resin binder and beads may be dropped after curing. There is a problem that can be.

Before the resin binder is cured as described above, the beads injected onto the resin binder are cured and fixed by the resin binder 2 coated on the adhered surface of the structure 1 as shown in FIG. A bead protrusion 3 protruding from the top is formed.

In addition, a glass powder (glass powder) may be further mixed with the resin binder and applied to the adhered surface.

The glass powder has a thermal expansion coefficient similar to that of the resin binder, and thus does not cause gaps due to thermal contraction and expansion, thereby improving the bonding force between the beads and the resin binder so that the beads do not fall off or fall off, and the like on the light surface and the luminaire reflecting surface. The adhesion of contaminants can be prevented more effectively. In addition, the glass powder suppresses interfacial separation and absorbs and transmits an impact applied from the outside, thereby forming a coated surface structure in which damage is significantly reduced.

The glass powder may be used in a variety of particle shapes and particle sizes, the particles of the glass powder is obtained by pulverizing glass, cullet, glass fiber, or glass curette, glass composition is A, C, E, alkali resistance It will not specifically limit, if it is compatible with resin binders, such as a glass powder composition, Especially, glass powder of an E-glass composition is more preferable at the adhesiveness with respect to various raw materials.

Although the particle diameter of the said glass powder is not specifically limited, Especially 1 micrometer-1 mm are preferable, More preferably, it is 5 micrometer-1 mm. If the particle diameter of the glass powder is too small, there is a problem in that the binding force improvement effect between the beads and the resin binder is insignificant. If the glass powder is too large, the glass powder cannot be uniformly mixed with the resin binder. There is a problem that it can increase.

The glass powder is preferably contained in 20 to 50 parts by weight based on 100 parts by weight of the resin binder solid content. If the content is less than 20 parts by weight, there is a problem in that the binding force between the bead and the resin binder is insufficient, and if the content exceeds 50 parts by weight, the content of the resin binder is relatively reduced, so that the adhesion of the coated surface to the adhered surface is reduced. There is a problem that this can be degraded.

In addition, the resin binder may further include a glass fiber (glass fiber) as needed. The glass fiber acts to increase the tensile strength and crack resistance of the cured coating surface.

The glass fiber may be a long glass fiber of the E composition or a fiber of an alkali resistance composition, specifically, a chopped fiber cut into glass or carbon fibers having a fiber diameter of 10 to 20 ㎛ in a uniform strand length (chopped fiber) ) Or milled fibers prepared by milling to an average fiber length can be used. In particular, the chopped fibers are preferably cut to a fiber length of about 100 to 500 μm, and the pulverized fiber preferably has an average fiber length of 100 to 300 μm. In particular, the pulverized fiber is preferable when considering the tensile strength reinforcement and dispersibility of the coated surface, and may be used by mixing the chopped fiber and the pulverized fiber.

The glass fiber is preferably contained in 1 to 100 parts by weight based on 100 parts by weight of the resin binder solids. When the content of the glass fiber is within the above range, there is an advantage that cracking, shrinkage, and expansion of the cured coating surface do not occur.

In addition, the resin binder may further include additives such as conventional fillers, conductive fillers, pigments, reaction catalysts, thickeners, flow control agents, wetting agents, UV stabilizers, or anti-settling agents, as necessary. In particular, the conductive filler includes a conductive powder and the like, which is included in the resin layer, thereby adding conductivity to thereby suppress static electricity and further increase pollution resistance.

In addition, the resin binder may further include a light reflector powder as needed. This is to improve the brightness by making the reflection of light more smoothly according to the addition of the light reflector powder, the flake aluminum powder, stainless steel powder, mica powder, etc. having good reflectance may be applied thereto. Preferably, 1 to 20 parts by weight may be included with respect to 100 parts by weight of the resin binder, and the size thereof may have a range of sizes, and more preferably, it has a size of 0.01 μm to 1 mm in terms of reflection effect. Alternatively, a similar effect can be obtained by directly using a metallic paint as the resin binder. The metallic paint mainly uses flaky aluminum powder, and a mica color paint or pearl color paint, which is replaced with a mica, can also be used. Can be.

The coating layer having the above structure can be applied to a lamp or a luminaire having an adhered surface to which deposits such as dust or contaminants are attached in a conventional manner.

That is, a resin binder and a mixture of glass powder, glass fiber, or additives are directly applied to the adhered surface corresponding to the glass surface of the lamp or the reflective surface of the luminaire, and the mixture containing the coated resin binder is applied. There is a method of adhering and curing the beads on the resin binder by spraying the beads before curing.

The formation of the coating layer as described above may be formed on the adhered surface of the lamp or the luminaire already installed, or may be formed directly on the surface of the new lamp or the luminaire while manufacturing.

The resin binder and a mixture of glass powder, glass fiber, or additives as necessary may be selectively used by using a conventional coating method used in the art according to the material, requirement, area, etc. of the surface to be coated. Of course, it can be applied to a nonwoven fabric, and in particular, if the components are likely to be scattered when applied in an outward direction of gravity, it is preferable to prevent them from scattering by using a roller or a brush, and the components may not be scattered. In this case, it is preferable to use a spray coating.

The thickness of the coating layer formed by the above method can be adjusted in consideration of the material or performance of the surface to be formed, and in particular, the thickness of the coating layer which is a layer obtained by adding the thicknesses of the resin binder layer and the bead layer to the surface to be deposited It is preferable to coat to a thickness of 5 μm to 3 mm.

According to the luminaire and the lamp of the present invention as described above, in the coated luminaire and the lamp, the projection formed by the beads on the surface of the surface to be formed irregularly curved, thereby reducing the contact surface between the surface and the dust attached to the adhesion Once attached, they can be easily removed by minimizing the contact surface. In addition, when contaminants such as dust are formed in the unevenness formed by the bead protrusions, the contaminants can be easily removed by washing, thereby having an excellent effect on fouling resistance. In addition, such a coating surface can be easily constructed, there is an advantage that can improve the physical properties such as weather resistance, stain resistance, scratch resistance, chemical resistance, impact resistance of the adhered surface.
