Abstract

PROBLEM TO BE SOLVED: To prevent both hydrophilic and hydrophobic adhesive substances from adhering to the surface of a member and keep the surface clean by forming a surface layer, in which both hydrophilic and water repellent parts are dispersed in micro level, on glass cover surface. SOLUTION: A lighting system 10 is buried and has a housing 14 buried in a concrete wall 12. A light source 16 is covered with a cover glass 18. As the light source 16, a low pressure sodium lamp, high pressure sodium lamp, a fluorescent lamp, a mercury lamp, a fluorescent mercury lamp, other types of electric lamps can be employed. A practically transparent surface layer 20 having a structure in which hydrophilic parts so exposed as to bring photocatalytic oxide particles into contact with outside air and water-repellent parts exposed to bring water-repellent fluororesin into contact with outside air are dispersed in a micro level is formed on the outer surface of the glass cover 18. The film thickness of the surface layer 20 is preferably set to be 0.4μm or thinner. Consequently, opaqueness due to diffused reflection of light rays can be prevented and practically transparent property can be obtained.

する。The cleaning of tunnel lighting devices often requires traffic regulation and hinders smooth road traffic. Especially in tunnels, it is not only difficult to regulate traffic for cleaning lighting equipment,
Due to the considerable danger, it is not possible to carry out a thorough cleaning. In addition, since cleaning is a high-altitude operation and requires a long time, the time for traffic regulation tends to be long. In view of the above circumstances, an object of the present invention is to provide a tunnel lighting device in which the surface of a cover glass is not easily stained.

A surface layer having a structure in which both a water-repellent portion exposed so that the water-repellent fluororesin comes into contact with the outside air and having a structure in which both surfaces are microscopically dispersed is formed. Provide equipment. In such a structure,
Since the hydrophilic surface and the water-repellent surface are adjacent to each other, the hydrophilic attachment that easily adapts to the hydrophilic surface does not adapt to the adjacent water-repellent portion. Conversely, hydrophobic deposits that are easily adapted to the water-repellent surface do not adapt to adjacent hydrophilic portions. Therefore, neither the hydrophilic deposit nor the hydrophobic deposit is fixed to the member surface, and the surface is maintained in a clean state. Furthermore, the presence of the photocatalyst causes the photocatalytic oxide particles to be exposed so as to be in contact with the outside air in response to the photoexcitation of the photocatalyst, so that the hydrophilic portion is permanently maintained. The structure in which both the water-repellent and water-repellent portions are microscopically dispersed on the surface is maintained.

Whether or not it has the structure described above can be confirmed by the following method. One such method is performed as follows. That is, first, a solution containing a metal having a large atomic number such as Ag, Pt, or Pd such as silver nitrate, silver lactate, chloroplatinic acid, or palladium chloride is applied to the substrate surface, and the substrate surface is irradiated with excitation light of a photocatalyst. Ag, P
A metal having a large atomic number, such as t or Pd, is deposited on the substrate surface. Since the deposition reaction of the metal is based on the reduction action of the metal by the photocatalyst, at this time, the metal adheres to the hydrophilic portion exposed by the photocatalytic oxide particles in contact with the outside air, but the water-repellent fluororesin Is hardly adhered to a portion exhibiting water repellency exposed so as to be in contact with the outside air.
Next, by observing the reflected electron image of the scanning electron microscope, if the density (contrast) is dispersed, the photocatalytic oxide particles are exposed so as to be in contact with the outside air and exhibit a hydrophilic property. It is concluded that both the water-repellent portions exposed so that the fluororesin comes into contact with the outside air have a structure microscopically dispersed on the surface. As another observation method, elemental analysis of the surface may be performed using an energy dispersive X-ray analyzer (EDX) or an electron probe microanalyzer (EPMA) instead of observing the density using a backscattered electron image. . As another observation method, if the metal is colored such as silver, the color may be observed by an optical microscope instead of observing the density by a reflected electron image.

It can be fixed by a method such as a combination of pressure treatment and the above heat treatment, or fixing by impact pressure. Further, before fixing by the above method, the surface of the substrate may be blasted or the like to provide irregularities. Then, the adhesion between the substrate and the surface layer can be improved.
