Description

  The present invention provides safety for people in emergency situations, such as when a fire or earthquake occurs in a tunnel, for example, in a highway tunnel, in a subway station, an underground mall, or the like. The present invention relates to a guide light in a sinus for instructing an evacuation route and guiding to an evacuation route when guiding to a place and condemning it.

  Conventionally, in the event of an emergency such as the occurrence of a fire, the means to transmit information necessary to people in the cave has been defined in our company regulations in accordance with the Fire Service Act. As this means, emergency exit guidance that guides people to the evacuation route A light is used.

  As shown in FIG. 4, the emergency exit guide light is a U-shaped casing made of synthetic resin such as acrylic, for example, which represents a mark for evacuating people using two colors of green and white. 11, for example, a light source 12 such as a fluorescent lamp such as FL10W is provided, and connected to a circuit component 13 such as a charging circuit, a lighting circuit, COM, and a ground, and an AC power source 14.

Moreover, as a conventional emergency exit guide light, as disclosed in Patent Document 1,
In normal times, the guide light unit turns on the fluorescent lamp. When the normally closed contact of the Xenon lamp is cut off by disconnecting the normally closed contact of the xenon lamp, the induction noise caused by the high frequency lighting of the xenon lamp is induced via the first electric circuit and the second electric circuit. There is an evacuation guide light or the like that does not adversely affect the flashing lamp unit and does not cause the induction noise caused by lighting the fluorescent lamp to adversely affect the flashing lamp unit.

Furthermore, as disclosed in Patent Document 2, the display includes a light-emitting body for display, a lighting circuit for lighting the light-emitting body for display, and a battery for supplying power to the lighting circuit. A light unit is formed, and a front panel, a milky white acrylic display plate on which letters and symbols of guidance contents in an emergency etc. are drawn, an inspection unit, the guide light unit, and a substrate for connecting them There is an emergency guide light panel or the like provided with a wiring connection box provided inside the box.
JP 2000-223283 A JP-A-9-231818

  However, the emergency exit guide lights in the sinuses that have been used conventionally have been lit for 24 hours, and therefore frequently run out of balls. For example, the lifetime of the fluorescent tube 10W was very short, about 6,000 hours (8.3 months).

  Moreover, since the conventional emergency exit guide light is a fluorescent tube, for example, in the replacement work of the fluorescent tube, the emergency guide light is mounted at a high position, so the replacement work of the fluorescent tube is performed at a high place. It became work and was dangerous.

  In addition, using conventional fluorescent tubes consumes a large amount of power (29,808 yen per month in the Shinjuku branch office holding area), which increases maintenance costs.

  Furthermore, since the power consumption is relatively large, the emergency exit guide lamp itself tends to become high temperature, and when it deteriorates over time, it may cause a fire.

  In Patent Document 1, since a fluorescent lamp and a xenon lamp are used in combination, the installation space increases and the overall weight also increases.

  In addition, considerable maintenance and labor are required for maintenance such as replacement of both lamps.

  Further, in Patent Document 2, a front panel, a display plate, an inspection unit, a guide light unit, and a wiring connect box having a board for connecting them inside the box are provided. As in the case of 1, the installation space is increased and the overall weight is also increased.

  Moreover, maintenance such as replacement of both lamps has a problem of requiring considerable costs and labor.

  Therefore, the present invention was created in view of the existing circumstances as described above, and can reduce power consumption. Also, it is a lightweight and thin type that extends the life of the light source and reduces the running cost. The purpose is to provide a guide light in the cave.

  A guide light in a sinus according to the present invention includes a translucent display panel in which characters and symbols of emergency contents are drawn on the surface, and a thin organic EL thin film incorporated in the display panel. The above-described problems have been solved.

  In addition, the organic EL thin film is a thin film using a phenomenon in which electrons or holes are injected from the outside as carriers and recombined in the phosphor, thereby solving the above-described problem.

  Furthermore, the display panel is formed in a state in which two sheets of light-transmitting polycarbonate plate material formed into a thin rectangular panel shape are aligned in the front-rear direction through a slit portion through which an organic EL thin film can be inserted. As a result, the above-mentioned problem has been solved.

  Further, the display panel includes a thin housing portion for inserting a thin plate-shaped organic EL thin film, and is connected to the organic EL thin film housed in the thin housing portion on a flange portion formed on the opening side of the thin housing portion. The above-mentioned problem was solved by fixing the molded connector via the rubber packing.

  In addition, the display panel has an opening on the upper side, thereby solving the above-described problem.

  Further, the display panel is formed by a transparent glass sealed case using an embedded induction coil with a small battery built therein, thereby solving the above-mentioned problem.

  A guide light in a sinus according to the present invention includes a translucent display panel in which characters and symbols of emergency contents are drawn on the surface, and a thin organic EL thin film incorporated in the display panel. By providing the above, it is possible to reduce the power consumption during lighting. Further, by using the organic EL thin film, the life of the light source can be extended and the running cost can be reduced.

  For example, in the Shinjuku branch office holding area, at present, 2 yen / 10h × 24h × 30 days × 270 lights = 29,808 yen / month, and an annual cost of approximately 360,000 yen was required. .

  However, since the organic EL thin film consumes about 1/3 of the conventional fluorescent tube, the cost of about 120,000 yen per year is sufficient, and the cost of about 240,000 yen is reduced. be able to.

  Further, the guide light in the sinus according to the present invention can reduce the replacement cost of the light source of the guide light. That is, since the life of the conventional fluorescent tube is shorter than the life of the organic EL thin film, the guide light in the sinus according to the present invention is expected to reduce the repair cost when the bulb is broken.

  For example, as a replacement cost of the fluorescent tube, the fluorescent tube is replaced at the place where the worker can reach at the time of inspection, but the material cost alone costs about 500 yen. Further, in places where workers cannot reach, fluorescent tubes are replaced by individual design (scaffolding, etc.). However, if this is carried out, it costs about 30 thousand yen to 70 thousand yen. In the sinus according to the present invention, these costs can be significantly reduced by using the organic EL thin film.

  Moreover, the work frequency at high places can be reduced by the guide light in the sinus according to the present invention. That is, since the life of the organic EL thin film is longer than the life of the fluorescent tube, the replacement work frequency (work at a high place) when the bulb is broken can be reduced.

  For example, the lifetime of the fluorescent tube 10W is about 6,000 hours = 8.3 months, and the replacement frequency needs to be performed once every 8.3 months, whereas the lifetime of the organic EL thin film is about 70 Since .000 hours = about 8 years, the replacement frequency only needs to be performed once every 8 years. Further, by adjusting the luminance (lowering the voltage), it is possible to further extend the life of the organic EL thin film (more than 10 years is possible).

  Furthermore, the organic EL thin film used in the present invention is pollution-free. That is, since it does not contain mercury or the like as compared with a conventional fluorescent tube, it does not emit ultraviolet rays or the like. Moreover, even if the use of mercury-containing products is regulated in the near future, it is possible to cope with this. In addition, since the entire structure is simple, there is no risk of powder or liquid flowing out even when subjected to an impact. In addition, the company image can be improved by removing mercury.

  In addition, the organic EL thin film used in the present invention is extremely thin and lightweight. That is, the thickness of the thin film main body is 2.2 mm and the weight is as light as about 100 g (equivalent to 4 inches), so that it can be easily removed and transported. For example, it can be used as a temporary emergency exit indicator lamp during construction. . In addition, the power supply device can be downsized at the same time. In addition, since the panel itself is thin, it can be installed in the passage (floor surface), which is effective during evacuation.

  Moreover, since the organic EL thin film used in the present invention has less heat dissipation than the fluorescent tube, the temperature rise in the tunnel can be suppressed.

  Furthermore, if a display panel is changed, it can utilize also for another guidance display. For example, the organic EL thin film can be used as various backlights by changing the display panel by using the organic EL thin film as a backlight.

  Further, since the organic EL thin film used in the present invention can be formed into a free shape (for example, a circle, a rectangle, a triangle, etc.), for example, it can be formed into an arrow shape as a new proposal of a guidance display method. Furthermore, the organic EL thin film can be attached at any location, and the attachment location is not limited.

  In addition, the organic EL thin film used in the present invention has no luminance unevenness (such as a shadow). That is, since the organic EL thin film itself is surface emitting, there is no luminance unevenness (such as a shadow), and clear guidance display is possible.

  Moreover, the organic EL thin film used in the present invention can be enlarged. For example, as a new proposal of the guidance display method, it is possible to mold the door size or the like.

  In addition, the organic EL thin film used in the present invention can be used as a lighting device for a sinus. That is, the number of illumination lamps can be reduced by having the functions of both guide lights and lighting fixtures. For example, when it is used for illumination, it is possible to reduce the size of the tunnel. In addition, it can be used as a lighting facility for narrow facilities (such as in a cupicle).

  It can also be used for purposes other than guide lights. For example, the degree of safety is improved by incorporation into a lifting device (handrail or the like). Alternatively, by reducing the organic EL thin film and forming it like an oil tank oil level gauge, it can be used for facilities that cannot be inspected unless illuminated by a flashlight.

  Furthermore, the organic EL thin film can be used by incorporating it into a night safety vest or used for road traffic signs. Further, the organic EL thin film can be used by being incorporated into various display boards for night construction, or can be incorporated into a road color cone. Alternatively, the organic EL thin film can be used for lighting up various exhibits (from the floor), or used as a copy-print. Moreover, application to the tip nozzle of a vacuum cleaner (for cleaning in a dark place) is also possible.

  In addition, the organic EL thin film can be used as a shining card for a present or the like, or can be used as a shining picture book. Further, the organic EL thin film can be used as a bicycle reflector or as a backlight for a wall clock. Furthermore, the organic EL thin film can be used as lighting in a camping tent (attached to a tent and packed as it is), or used as street lighting (street light by being attached to a power pole / building wall). In addition, the organic EL thin film can be used as illumination for preventing a staircase fall (attached to a stepped portion of a staircase) or used for a bath tab (creating a healing space by shining the entire surface of the bath tab).

  In addition, the organic EL thin film is a direct current device having an anode and a cathode at both ends. The thin film has a laminated structure, and by increasing the current density, it is possible to obtain high-luminance light emission by direct current low voltage driving (3 to 12 V), so the time for lighting and maintaining the brightness is about 60,000 hours. It is about 100,000 hours (about 7 to 11 years), and the life of the light source is extended. If the brightness is adjusted (the voltage is lowered), the life of the organic EL thin film can be further extended (more than 10 years is possible).

  Further, the lighting state and the extinguishing state can be appropriately selected and used within the lifetime of the light source.

  Furthermore, the organic EL thin film can be continuously lit only by using about 3 W of power.

  Further, the weight of the organic EL thin film itself is as light as about 100 g (equivalent to 4 inches), and since it is thin and does not take up space, the mounting work at a high place is very easy.

  In addition, the display panel is formed in such a manner that two sheets of light-transmitting polycarbonate plate material formed into a thin rectangular panel shape are matched in the front-rear direction through a slit portion through which an organic EL thin film can be inserted. Therefore, it is very easy to assemble and replace the organic EL thin film on the display panel.

  Further, the display panel includes a thin housing portion for inserting a thin plate-shaped organic EL thin film, and is connected to the organic EL thin film housed in the thin housing portion on a flange portion formed on the opening side of the thin housing portion. Since the molded connector is fixed via the rubber packing, the waterproofness of the display panel can be reliably maintained.

  In addition, since the display panel has an opening on the upper side, the organic EL thin film can be easily taken in and out.

  In addition, the display panel can reliably retain the waterproofness of the display panel in that it is formed of a transparent glass sealed case using an embedded induction coil incorporating a small battery.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a guide lamp 1 in a sinus according to the present invention is generally composed of a thin rectangular panel-shaped display panel 2 having translucency and an organic EL thin film 3 built in the display panel 2. It is configured. This organic EL thin film 3 means a carrier injection type organic EL thin film.

  For example, the display panel 2 is made of two transparent polycarbonate plates formed into a thin rectangular panel having a width of about 400 mm and a length of about 150 mm, and is aligned with the front and rear through the slit 4. It is formed in a state of being allowed

  As shown in FIG. 1, the organic EL thin film 3 is inserted into the slit portion 4 between the front and rear display panels 2 from the lower side. The insertion direction of the organic EL thin film 3 may be from the upper side of the display panel 2 or from the lateral side.

  Further, the peripheral portions of the front and rear display panels 2 are fixed by a fastening member (not shown).

  On the surface of the display panel 2, characters, symbols and the like of guidance contents in an emergency etc. are drawn with backgrounds of respective colors. For example, as shown in FIG. 1, a mark or the like for evacuating a person is drawn with two colors of green and white.

  The display panel 2 formed in this way is attached to the ceiling of the evacuation route, the upper wall surface side of the opening of the emergency door, or the like via an attachment jig (not shown).

  An inverter 5 is connected to the transparent electrode of the organic EL thin film 3, and an existing emergency battery 6 is connected to the inverter 5. For example, the organic EL thin film 3 emits light when a commercial AC power supply of 100 V is stepped down by a transformer 7 built in the inverter 5 and then rectified to direct current by a diode bridge or the like and applied to a transparent electrode. .

  The organic EL thin film 3 has a lifetime of about 60,000 hours to 100,000 hours (about 7 years to 11 years), and can be manufactured and used in a free form.

  In particular, the organic EL thin film 3 can be continuously lit only by using about 3 W of power, but can be lit by switching the emergency battery 6 only during a power failure.

  Further, since the organic EL thin film 3 has a weight of about 100 g (equivalent to 4 inches) and is lightweight, the mounting work at a high place is very simple.

  Next, an example of use / assembly of the guide light 1 in the sinus constructed as described above will be described.

  First, as shown in FIG. 1, the organic EL thin film 3 is inserted into the slit portion 4 between the display panels 2 and disposed between the display panels 2.

  In this state, the peripheral portions of the front and rear display panels 2 are fixed by a fastening member (not shown).

  The display panel 2 is attached to the ceiling of the evacuation route, the upper wall surface side of the opening of the emergency door, or the like via an attachment jig (not shown).

  The inverter 5 is connected to the transparent electrode of the organic EL thin film 3, and the existing emergency battery 6 is connected to the inverter 5. Each of the inverter 5 and the emergency battery 6 is arranged and fixed at a predetermined position near an evacuation route or an emergency door via a cable.

  The organic EL thin film 3 is always lit by a commercial AC power supply of 100V.

  Alternatively, the organic EL thin film 3 is activated by switching the emergency battery 6 in the event of a power failure when a disaster occurs.

  At this time, the whole surface of the organic EL thin film 3 emits light by being directly applied to the transparent electrode from the emergency battery 6.

  As a result, the entire display panel 2 is turned on with high brightness, and an evacuation route for guiding a person to a safe place is instructed and guided to the evacuation route.

  On the other hand, FIGS. 2 (a), (b), and (c) show a specific configuration of the guide lamp 1 in the sinus according to the present invention by a waterproof system.

  The guide lamp 1 includes a slit-shaped thin housing portion 11 for inserting the organic EL thin film 3 into a thin rectangular panel-shaped display panel 2 made of, for example, polycarbonate, whose front and rear are translucent surfaces. ing. The display panel 2 has an opening at the top.

  A flange portion 12 that is wide in the front, rear, left, and right sides is formed on the opening side of the thin housing portion 11, and a rectangular plate-shaped molded connector 13 that is the same as the width of the flange portion 12 is connected to the loop rubber packing 14. It is put through. The mold connector 13 is connected to the transparent electrode 3 c of the organic EL thin film 3 accommodated in the thin accommodating portion 11. Further, after the upper side of the mold connector 13 is pressed by the cover plate 15, it is fixed to the cover plate 15 by the set screw 16 from the lower side of the flange portion 12 via the mold connector 13. In this way, the thin housing 11 is completely waterproofed by being blocked by the molded connector 13 via the rubber packing 14.

  3 (a) and 3 (b) show a specific configuration of another waterproof system of the guide light 1 in the sinus according to the present invention.

  That is, the display panel 2 is a transparent glass sealed case having a substantially T-shaped cross section, and the organic EL thin film 3 is sealed in the display panel 2 in a sealed manner. And since it is completely cut off (completely waterproofed) from outside air or the like, it is possible to extend the life of the organic EL thin film 3 by adjusting the brightness (lowering the voltage) (more than 10 years is possible).

  A 9V small battery 17 is built in the upper side of the display panel 2, and an embedded induction coil 18 is attached adjacent to the small battery 17. Thus, since the small battery 17 is built in the sealed case-like display panel 2, an external large battery that has been conventionally used can be omitted, and by being cordless, it is easy to carry. .

  The guide light in the tunnel according to the present invention is used in an emergency such as a fire or an earthquake in a tunnel of an expressway, a subway station, an underground mall, for example, an office building or a public facility. It can be widely used as a guide light for instructing the evacuation route and guiding it to the evacuation route when evacuating a person to a safe place during a power failure.

It is a perspective view which shows the assembly | attachment state of the organic EL thin film to a display panel. The other concrete structure of a guide light is shown, (a) is a disassembled perspective view, (b) is a front view, (c) is a side view. The other specific structure of a guide light is shown, (a) is a front view, (b) is a side view. It is a perspective view which shows the structure of the emergency exit guide light in a prior art example.
