Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guidance system using light emitting blocks suitable for installation on roads, walls, etc.

The recent development of underground malls, tunnels, hotels, and other structures has been remarkable, but on the other hand, once a disaster such as a fire or earthquake occurs, it tends to lead to a very large disaster.

For this reason, various studies have been conducted on evacuation guidance, but nothing satisfactory has yet been found.

One method of evacuation guidance is to indicate evacuation exits and emergency exits using electrically lit display boards, but these are not very effective in the event of a disaster because the displays are fixed. It is also possible to use a light emitting device to blink a light source with directionality, but if you simply install a light source using a light bulb or the like, you may need to surround it with something rigid to protect the light source such as a light bulb. They often have to be covered, and are often installed protruding from the surface of roads, walls, etc., which can obstruct walking and spoil the aesthetics.

In order to avoid obstructing walking or detracting from the aesthetics, a guidance display board (for example, a guide display board (for example, -89284) has been proposed, but because it is a surface light emitter, the brightness is extremely low.

The present inventors previously developed a light-emitting block (patent application) in which a light-emitting body with a light source integrated into an abradable light-transmitting material was embedded in an abradable composite material with the light-emitting surface of the light-emitting body exposed on the surface. 5-183854) was developed.

The present invention was made in view of these points,
The composition is made of a composite material that wears away in response to road surface wear, and a light emitting body with a light emitting diode integrated into a translucent material that wears out in response to road surface wear, with the top surface exposed on the surface. The blocks buried in this way are placed continuously on roads, walls, etc. to serve as guidance display lines, and the blinking of these light-emitting bodies is controlled by a controller. The guidance device is characterized in that the blinking is continuously directional and indicates the direction of the guidance location.

Next, embodiments of the present invention will be described based on the drawings.

Figure 1 is a perspective view showing the outline of the light emitting block, Figure 2 is a perspective view of the light emitting block illustrating the state in which the light emitter is embedded in the composite material, and Figure 3 is a perspective view showing the outline of the light emitter. It is.

The light-emitting block 1 is embedded in a wearable composite material 2, such as resin mortar, so that the surface of the light-emitting body 3 is exposed on the surface of the composite material 2, and is formed to an appropriate size. The light emitting body 3 is made of a wearable and translucent material, such as acrylic resin or vinyl chloride resin, to an appropriate size, and is formed by burying a light source 4, for example, a light emitting diode, in the lower part of the interior to provide brightness. ing. Acrylic resin, vinyl chloride resin, etc. may cause diffuse reflection of light when worn, and to prevent this, it is recommended to use a necessary diffusing material in the resin. A light emitting body 3 embedded in a composite material 2 constituting a light emitting block 1
Usually, they are buried in a complex form at appropriate intervals, but it is of course possible to bury them in a single form depending on the size. The size of the light-emitting block may be appropriately determined in consideration of the guidance display line during evacuation.
In addition, in the figure, 6 is a lead wire, and 5 is an outlet socket provided as necessary.

As a whole, wiring necessary for light emission is provided to form a light emitting block.

The light-emitting blocks constructed in this manner are installed, for example, in an underground mall, by being buried continuously in the sidewalk 7 at regular intervals in the length direction, as shown in FIG. form. Incidentally, in the present invention, the term "continuously installed" includes both cases in which the devices are installed continuously with intervals as in this embodiment, and cases in which they are installed continuously without any intervals. Naturally, the light-emitting block 1 is buried with its light-emitting surface facing upward. At this time, the light emitting block 1 is installed so that the surface of the road 7 and the surface of the light emitting block 1 are substantially flush with each other. The same applies when installing on a wall.

The installed light emitting block 1 is the light source 4 of the light emitter 3
It is wired through lead wires 6, and blinking is controlled by a controller.

An embodiment of blinking control of the light emitting block 1 will be described below with reference to FIGS. 5 and 6.

In Figure 5, A is a 100V AC commercial power supply, B is a controller, and C is a battery.
Battery C is charged with AC 100V commercial power supply A, and in an emergency, the power is automatically switched to battery C to control the light emitting block D of the display line. The blinking of the light-emitting blocks is divided into appropriate numbers and controlled by each controller.
Specifically, the control system is shown in Fig. 6. Controllers B1, B2, B3, B4, and B5 each control the number of light-emitting blocks within the arrow range. For example, when a fire is detected by the sensor of controller B2, repeats the flashing of the luminous body of the light-emitting block with the direction to emergency exit R or S bordering on A on the guidance display line, and if a fire is detected by the sensor of controller B3, exit R or emergency exit bordering P The light-emitting body of the light-emitting block with directionality towards S repeats blinking.

Thus, when a disaster occurs, people are guided toward the emergency exits according to the blinking of the directional light emitters that appear on the guide line formed by the light emitting blocks.

The present invention is constructed in this way, that is, by embedding the light source in a translucent composite material and embedding it in another composite material, a compact light emitting block that wears out in response to road surface wear can be created. This structure protects the light source and makes it easy to install the guidance indicator line on the road surface or wall. does not occur. Furthermore, by controlling the light emission of the light-emitting body of this light-emitting block by a controller and repeating the directional blinking of the guide direction on the guide display line, it is possible to easily guide people. Incidentally, such a system is used not only when a disaster occurs, but also to guide vehicles, aircraft, ships, and people not only to roads but also to locations and directions according to their purposes.
