Description

Night light reflection device capable of preventing oily graffiti and preventing propaganda material from being adhered by adhesive
Technical Field
The present invention relates to a night light reflection device capable of preventing oily Graffiti and preventing adhesion of a propaganda material using an adhesive, and more particularly, to a night light reflection device capable of preventing oily Graffiti and preventing adhesion of a propaganda material using an adhesive, which can prevent various facilities installed for public purposes, such as a street lamp, a utility pole, a distribution box, a subway wall, or a personal building wall, from being Graffiti, paint (Graffiti) Graffiti (universal paint and universal pen), can prevent arbitrary adhesion of illegal propaganda materials, and can ensure visibility through light reflection at night or in rainy weather.
Background
Accidents that occur as a result of random crossing of roads are increasing dramatically each year nationwide, one of the reasons being the lack of traffic awareness among pedestrians and insufficient publicity associated with the prevention of traffic accidents. In addition, the main causes of the occurrence of a traffic accident for children in the vicinity of elementary schools are traffic congestion caused by driver's carelessness and vehicle violation in an area where parking of vehicles is prohibited. Therefore, it is possible to prevent traffic accidents, traffic accidents of children around primary schools, traffic accidents caused by traffic jams due to illegal vehicles, etc. by providing traffic accident prevention promotion materials, and it is also possible to enhance the safety awareness of the whole population by providing various prompting or warning public welfare promotion materials.
However, even if the aforementioned public service materials with a warning or indication property are installed in a conspicuous roadside public facility, there is a possibility that the city street landscape may be damaged due to oil Graffiti or paint (Graffiti) Graffiti for personal advertisement or malicious advertising purposes on the surface thereof, and there is a possibility that the public service materials may be hidden due to actions such as sticking paper advertisement materials for personal business promotion with glue, stickers, and foam tapes, or marking telephone numbers with oil-based universal pens, and further there is a problem that the city appearance of the public service materials with the inherent color of the city public facility or public service purposes may be hardly distinguished.
In addition, recently, a quick response code (QR) is printed on public service promotional materials, and when the quick response code (QR) is partially covered by oil Graffiti for promotion, paint (Graffiti) Graffiti, or the like, or personal advertising paper advertising materials are randomly attached to the quick response code (QR), the quick response code (QR) may be damaged or its function may be damaged. Further, when a government that manages the above-described behaviors uses a sharp blade or the like for removing graffiti and promotional materials, there may be a problem of rusting due to the surface damage of the original facility, and when general paint is used to cover graffiti and promotional materials, there may be a problem of damage of a quick response code (QR) or a functional damage thereof.
In particular, pillars, walls, entrance doors of apartments, signal light control boxes, street light control boxes, and distribution boxes of electric power companies, etc., of buildings, are generally located at roadside locations where public vision is most easily accessed, and thus are easily selected as a propagation path of personal promotional materials, so that the phenomenon of oil-based general pen Graffiti or paint (Graffiti) Graffiti and sticking of promotional materials using an adhesive occurs. The random graffiti contents or the attached documents on the surfaces of various individuals or public facilities as described above have a bad influence on the aesthetic property, and if the above-described state is left, such as a warning given in the breaking Window effect (Broken Window Theory), the problem of littering or personal and public facility damage due to moral numbness may occur, and further, the occurrence of serious crimes may occur, eventually leading to serious social problems.
In addition, in the night driving of a vehicle, other facilities such as a road post and a speed limit post installed on a road are very important for a driver who relies on high and low headlights of an automobile, and thus visibility of the road facilities is always a very important issue.
In order to remove publicity information using an oil-based universal pen for the purpose of illegal personal publicity and publicity paper advertisement material using telephone number Graffiti, paint spray (Graffiti) Graffiti or adhesives, government or local autonomous groups generally use a sharp iron spatula, but this causes damage to publicity materials for public use and surfaces of road facilities, and in severe cases, may even cause a problem of rusting, while only being covered with paint for the purpose of removing oil-based Graffiti, thereby seriously spoiling the beauty of city streets.
In order to prevent adhesion of promotional materials such as poster paper, for example, a strut cover made of a highly corrosion-resistant metal material has been proposed (korean registered patent No. 10-0566947); a post cover in which triangular stone grooves are continuously formed at the front side and formed in relief, and a space part functioning as a heat insulation when coupled to a post is formed at the rear side (korean registered patent No. 10-0952082); coating compositions comprising stone powder, acryl resin, polyvinyl acetate and water (korean registered patent No. 10-1412870), etc., but it is difficult to protect publicity materials for public use from the publicity information using an oil-based universal pen and the behaviors of telephone number Graffiti or paint spray (Graffiti) Graffiti, etc., and there is no suggestion about the light reflection function at night.
Therefore, the present inventors have developed a night light reflecting device which can easily erase oily universal pen Graffiti or paint (Graffiti) Graffiti on public facilities such as walls, utility poles, street lamps, signal lamps, etc. or personal facilities using general wet wipes, thereby improving the maintenance function of the inherent facilities, reducing the adhesive force on the surfaces of the facilities or the surfaces of art and craft prints, preventing adhesive components from remaining even when advertising paper, etc. are attached, easily removing illegal advertising paper, etc. without the aid of instruments such as a scraper, etc., and ensuring visibility through light reflection at night or in rainy days, thereby preventing oily Graffiti and preventing advertising materials from being attached using an adhesive.
