방수 LAMP DEVICE FOR WATERPROOF AND DUSTPROOF HAVING A UV-COATING LAYER}

The present invention relates to a waterproof and dustproof luminaire having a UV coating layer, and more particularly, a high-light reflecting plate for fixing a lamp and a transparent cover fitted with an airtight packing in a case accommodating a stabilizer are hermetically coupled / separated by a locking device. One surface of the high illuminance reflector is vacuum-deposited with aluminum and subjected to UV coating to improve reflection efficiency of light due to metallic gloss, and a UV curing paint layer having excellent reflection efficiency is UV coated to the floodlight cover for energy efficiency. Maximizing and blocking ultraviolet rays, preventing harmful light from being emitted and preventing the discoloration and discoloration of the floodlight cover.It is installed on the walls of underground passages, subways, underground parking lots and tunnels. It is invented to block the inflow of dust and the like and to prevent corrosion of the reflector and the floodlight cover and reduced illumination.

In general, since a lot of dust is generated in the basement such as underpass, subway, and tunnel, a lot of dust is generated, and therefore, lighting fixtures having moistureproof, waterproofing, and dustproof functions are installed. In order to emit enough light to illuminate the light, several lamps or reflectors are used to illuminate the light.

However, when irradiating light using a plurality of lamps, there is a problem in that the volume increases and the manufacturing cost and the constraints of the space increase and the energy consumption increases.

In addition, the reflector and the cover that transmits light are corroded, discolored, and discolored over long periods of time, resulting in increased workload and economic losses due to problems such as the failure to reflect the light of the lamp, but rather the need to replace all the lighting fixtures. If the cover is damaged when installed in a place with severe vibration, there is a problem such as damaging the human body and the working environment.

It is also known that lamps differ in efficiency by ambient temperature. For example, the maximum luminous flux is obtained when the ambient temperature is 20 ° C to 25 ° C, but the lamp luminous flux is considerably lowered when the ambient temperature is higher or lower than this.

In particular, the luminaires used in underground, tunnels, subways and underground construction sites are susceptible to the influence of the ambient temperature, the lamp efficiency is easy to change.

After the vacuum deposition treatment with the hard-coated aluminum to improve the efficiency, UV coating treatment to prevent oxidation and corrosion of the vacuum-deposited aluminum layer.

On the other hand, vacuum evaporation is an operation of forming a thin film by evaporating a material such as a metal under high vacuum (generally about 10-4 torr) at high temperature (about 1,400 ° C.) and condensing and vaporizing the vapor on the surface of the cooled object. It is a deposition method that can be used for substances that may be oxidized while preventing collision between molecules evaporated through high vacuum and other molecules.

As the heating method for deposition, there are resistance heating, high frequency induction heating, EB heating, arc discharge heating, and the like. In the present invention, it is preferable to use high frequency induction heating which can obtain a relatively large amount of evaporation and an evaporation area.

In other words, lighting devices in places with high vibration such as subway and underground construction sites should be durable due to vibration and shock, and vacuum-deposit aluminum on lightweight and durable plates such as acrylic or synthetic resin.

That is, the exhaust valve 14 is provided in the main body 1, the air is exhausted from the exhaust valve 1 after the main body 1 is sealed, and the internal pressure is maintained in a vacuum state so that the external temperature is increased. It is possible to prevent the illumination efficiency from being lowered by being transmitted to the lamp 43 and to suppress the increase in the air temperature inside the main body 1 by the heat generation of the lamp 43, thereby stabilizing the temperature around the lamp 43. You can do it.

The floodlight cover 20 is a UV-curable paint is coated by the UV curing device to form a UV-curable paint layer, the airtight packing (30) of the cross-sectional shape of the silicon material in the groove 22 formed at the bottom (30) ), The lower surface of the hermetic packing () is brought into close contact with the pressing surface 13 of the case, and the locking device 11 is fastened to the locking projection 21 to be firmly fastened.

Here, the airtight packing 30 is first fitted to the floodlight cover 20, and the bottom surface of the airtight packing 30 is in close contact with the pressing surface 13, so that the elastic restoring force is secondary by the locking device 11. Since it is pressed while contacting, it will be able to completely block the inflow of moisture or fine dust in the double.

The UV-curable paint is a paint that uses a method of curing acrylate by the chemical action of ultraviolet light generated from the ultraviolet irradiation device, etc., the ultraviolet light of 200 ~ 400nm when the ultraviolet cured paint cures the chemical action of the self-energetic energy It reacts by, and an initial liquid paint hardens | cures to a solid phase.

The UV-curable paint is composed of a mixture of 35 to 60% by weight of acrylate oligomer, 35 to 60% by weight of reactive acrylate monomer, and 5 to 20% by weight of photoinitiator.

The acrylate oligomer is a acrylate urethane (acrylate urethane) is less than 35% by weight of the curability is less than 60% by weight, because the workability is poor, the acrylate urethane (acrylate urethane) ) Is preferably used at 35 to 60% by weight.

The acrylate monomers are acrylic acid, methyl acrylate, 2-hydroxyethyl acrylate, 4-hydroxybutyl acrylate, butyl acryl. At least one selected from the group consisting of butylacrylate, when less than 35% by weight, the curability is inferior, and when it exceeds 60% by weight, the workability is inferior. Thus, the acrylate monomer is 35 to Preference is given to using at 60% by weight.

The photoinitiator is any one or more selected from benzophenone, benzoin alpha methyl benzoin, alpha hydroxy methyl benzoin, benzoin isoflophyll ether, benzoin phenyl ether, and hydroxy cyclohexylphenyl ketone. In consideration of workability and adhesion, it is preferable to use it in the range of 5 to 20% by weight.

The coating process of the UV cured paint is to prevent the adsorption of dust and the like by stabilizing the protruding property of the coating film and the antistatic agent by using an ion gun or an air gun to prevent the generation of static electricity, the diameter is 0.8 ~ 1mm Apply at a pressure of 3 ~ 3.5Kg / ㎠ through air spray, etc., and apply IR (infrared ray) for 2 ~ 3 minutes at a temperature of 50 ~ 60 ℃ to give solvent volatilization and spreadability The film is stabilized by cooling for about 1 minute at room temperature, and UV coating layer is formed by irradiating UV light for 5-10 seconds to the stable coating part by using 80W / cm mercury lamp or metal halide lamp. Be sure to At this time, the distance between the workpiece and the lamp is preferably 15 to 20 cm.

By forming a UV coating layer on the floodlight cover through this process, it blocks light harmful to the human body, prevents discoloration and discoloration of the floodlight cover 20, and prevents moisture from being generated by the heat of the lamp 43 itself. Even if it is used for a long time, the light of the lamp 43 is effectively reflected.

That is, the light emitted from the lamp 43 is first reflected through the high illuminance reflector 40, and the reflected light passes through the UV coating layer formed on the floodlight cover 20, and then secondarily reflects the light. Using a low lamp or using a single lamp achieves the same high reflectivity as using multiple lamps.
