DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying and illuminating a road surface in a dark state at night or during a power outage in an automobile road, a pedestrian passage, an underground shopping mall, an underground passage, a building passage, a ship passage, a stairway, or the like. The present invention relates to a road surface member such as a tile, a block, a terrazzo or the like, which can safely walk or guide the vehicle.

[0002]

2. Description of the Related Art Conventionally, there has been no guide system on a road surface using a luminous body. In recent years, studies have been made on evacuation guidance using a luminescent material to ensure safety in the event of a power failure such as a disaster. However, the luminescent material is hydrolyzed as it is, and is generally used as a paint because of poor weather resistance.
A luminescent material has been mixed in a resin, and has begun to be used as a plate-like wall material in a portion requiring an induction effect. However, at present, resin-based light-emitting materials have not been used on roads and the like because of their poor weather resistance and wear resistance and poor durability.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a road surface member such as a road, a passageway, a floor surface, etc., on which a luminous display is formed on the surface so as to guide the line of sight and which can guide safe driving and evacuation at night or during a power failure. To provide.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is to be arranged on a passage such as a road or a floor, and has a fluorescent or luminous fluorescent property on a surface mainly of a road surface member such as a tile or a block. A light-emitting display road surface member having a configuration in which a light-emitting body containing a material is arranged to form a display for guiding or watching an arrow or the like. The luminous body may be arranged in a convex portion or a concave portion mainly composed of a road member for guiding a blind person having an uneven portion on the surface. Further, the light-emitting body may be formed into an inorganic particle by incorporating an inorganic light-emitting body containing a fluorescent material having a fluorescent or luminous fluorescent property into an inorganic base material such as ceramics.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described. The plate-like road surface member indicated by an arrow shown in FIGS. 1 and 2 has a light-emitting body 2 arranged on the surface of a concrete road surface member main body 1 containing a general aggregate 10 in cement so as to be indicated by an arrow. The material 10 and the luminous body 2 are slightly exposed from the surface.

The luminous body 2 can be integrally fixed to the road surface member 1 by arranging it on the surface of the concrete before the concrete is hardened. Alternatively, as shown in FIG. 3, after the road surface member main body 1 is cured, the light emitting body 2 may be fixed to the display unit via the adhesive 3.

Here, the luminescent material of the luminous body 2 may be a crushed phosphor or phosphorescent phosphor, and sulfides, halophosphates, silicates, tungsten and the like can be used. Aluminates are preferred from the viewpoint of brightness, and inorganic materials are appropriate. Further, the luminous body 2 is such that the luminescent material contains a resin base material or a ceramic base material.

As the resin base material, an MMA resin, an epoxy resin, an unsaturated polyester or the like is used as long as it is a resin having high transparency, but the MMA resin is preferable. In addition, as the ceramic base material, there is a material which is reactive at the time of melting and firing and must be individually selected depending on the fluorescent material, but a ceramic having a high transparency, a low content of transition metal oxides and heavy metals and a low melting point is used. Desirably, high purity borosilicate glass or the like is suitable.

Then, a luminescent material is added to the base material by 3 to 5 times.
The mixture is baked by mixing 0% by weight, and the mixture is pulverized to form the luminous body 2 in the form of granules. The luminous material is wrapped in the base material. Therefore, it is preferable to use an inorganic ceramic base material in order to obtain a high-intensity light-emitting body 2. When the luminescent material is less than 3% by weight, a predetermined luminous brightness cannot be obtained, and when the luminescent material is more than 50% by weight, mechanical or chemical durability gradually decreases and the cost becomes high, so that it cannot be adopted. A suitable range is 5-35% by weight.

According to this embodiment, the luminous body 2 is excellent in abrasion resistance due to its high-strength granularity, and the luminous body 2 emits light to provide a visual line guidance effect at night or during a power failure such as a disaster. . Therefore, traffic at night or during a power failure can be safely guided.

In the present invention, regardless of the material and size of the luminous body, it is sufficient that the luminous body contains a luminous material which exhibits luminous characteristics when irradiated with light. Not limited. In addition, as long as the light emission luminance can be secured, the light-emitting body may be mixed with the general aggregate and fixed to the surface of the road surface member, and the proportion thereof is also appropriate. This general aggregate is crushed stone,
A generally used porcelain or ceramic body such as alumina, silicon carbide or Emily may be used.

Further, the size and the material of the road surface member are also arbitrary, and may be blocks, tiles, various stone materials, and the like, and the luminous body fixing means is also appropriate. In addition, the display by the luminous body,
In addition to arrows, various functions such as line of sight, evacuation guidance, stop line, intrusion prohibition line, etc. are displayed systematically, individually or in combination, such as line of sight, branch line, dot, circle, line of sight or evacuation direction and position division. Is what you can do. An example of this display is shown in FIG. 4, but is not limited to this mode.

[0013]

According to the first aspect of the present invention, traffic at night and at the time of a power failure can be safely guided by the light emission of the luminous body. According to the second aspect of the present invention, the light emission can be seen well when the light emitting body is fixed to the convex portion, and the light emitting body has very little wear resistance when the light emitting body is fixed to the concave portion because the light emitting body is extremely low in durability. Furthermore, in claim 3, the durability is excellent.

Example 1 Strontium aluminate SrAl ₂ O ₄ having long-term afterglow characteristics as a phosphorescent fluorescent material, europium Eu as an activator, a ceramic base material, 30% by weight of the fluorescent material, ceramic 70% by weight of base material
The mixture was fired at 850 ° C. for 30 minutes and allowed to cool in a furnace to form an inorganic ceramic phosphor, which was pulverized to a particle size of 3.3 to 2.0 mm to obtain a granular phosphor. The composition of the ceramic base material was Si
O ₂ 52.0 wt%, Al ₂ O ₃ is 5.3 wt%, B ₂ O ₃ is 25.4 wt%, Fe ₂ O ₃ 0.03 wt%, TiO ₂ is 0.05 wt%, CaO 0.35
Wt%, K ₂ O is 2.35 wt%, Ng ₂ O 11.0 wt%, other 3.52
% By weight.

Further, a luminous body using an organic base material is formed by using europium Eu as an activator for the strontium aluminate SrAl ₂ O ₄ as a fluorescent material. 30% by weight of the fluorescent material and 70% by weight of an organic base material. The organic base material is an MMA resin, into which 2.5% of BPO is charged, and stirring polymerization is started at 80 ° C. Then, at the beginning of the increase in viscosity, the fluorescent material is charged and the temperature is raised by polymerization, and the polymerization is completed by cooling. This was pulverized to a particle size of 3.3 to 2.0 mm to obtain a luminous body.

These two types of luminous bodies were used alone or in combination, and arranged on the surface of a terrazzo tile as a flooring material as shown by arrows in FIG. An experiment of the light emission luminance of these light emitters will be described. The terrazzo tile was installed on the floor of an underpass, two 80 W fluorescent lamps were installed at a height of 4 m from the floor, and after 4 minutes irradiation, the lights were turned off and measured.

According to this, at the time of the new installation, the phosphorescent luminance of the inorganic and organic luminous bodies after two minutes of turning off the fluorescent lamp shows excellent luminous properties, and the phosphorescent luminance is sufficient up to 15 to 30 minutes. Evacuation guidance at the time of an emergency blackout or the like was possible using the light emission display, and it was visible even after 8 hours.

After a one-year practical test in the underground passage, the same test was conducted again. As a result, the luminance of the inorganic luminous body was sufficient as in the new construction, but the luminance of the organic luminous body was sufficient. As the wear of the surface progressed, the surface was blackened and the emission luminance was clearly reduced. As described above, both inorganic and organic light-emitting materials can be used for evacuation guidance by light-emitting display, but inorganic light-emitting materials were superior in terms of durability.

[0019]

Example 2 The inorganic luminescent material obtained in Example 1 was further pulverized into particles having a particle size of 0.5 to 0.15 mm to obtain a luminescent material 2, which was mixed with an MMA resin for top coat to which PBO was added. It was used for the blind induction tile 5. The mixing ratio is
The luminous body 2 is 80% by weight and the MMA resin is 20% by weight. In FIG. 6, the luminous body 2 is placed on the upper surface of the convex portion of the induction tile 5.
It is applied and fixed at a thickness of 8 mm. In FIG. 7, the luminous body 2 is applied and fixed with a thickness of 0.8 mm on the upper surface of the convex portion of the induction tile 5.

Then, the tile 5 was installed on the floor of an underpass, two fluorescent lamps of 80 W were installed at a height of 4 m from the floor, and after illuminating for 40 minutes, the measurement was performed. After the lights are turned off, sufficient phosphorescent brightness is shown for 30 minutes.
It was visible even after 8 hours.
