Embodiments of the present invention will be described below.
(Embodiment 1)
The guide light device A of the present embodiment has a segment light emitter 1 using the organic EL light emitting element shown in FIGS. 1A to 1C as a light source, as shown in FIG. It is constructed by connecting and arranging in a line on the surface.

  The segment light emitter 1 is formed by forming a back electrode provided on the surface of a thin and flexible substrate such as a polyacrylate film, and laminating an EL material on the surface of the back electrode to form a light emitting layer. A transparent electrode was formed on the surface of the light emitting layer, and the surface of the transparent electrode was covered with a flexible transparent sheet made of, for example, a polyacrylate film, and a rectangular light emitting surface was formed on the surface side. For example, a positive electrode extraction electrode 11a, 11b electrically connected to the back electrode is provided at both ends of the organic EL light emitting element 10, and an negative electrode extraction electrode 11a, 11b electrically connected to the transparent electrode is provided. Electrodes 12a and 12b are provided. In the embodiment, one of the extraction electrodes 11a and 11b at both ends is connected to the back electrode, and the one and the other are connected via auxiliary electrodes 11c and 11c made of silver pace or the like.

  Here, by making the back surface position of the electrodes 11a, 12a on one end (the upper end side in the figure) the same as the surface position of the electrodes 11b, 12b on the other end side, By overlapping the back surfaces of the electrodes 11a and 12a on one end side of the segment light emitter 1 with the surfaces of the electrodes 11b and 12b on the other end side of the other segment light emitter 1, the light emitting surface 10 is flush with each other. The segment light emitters 1 can be electrically connected in parallel.

  Thus, the segment light emitters 1 are connected in a line along the passage on the floor F of the passage of the installation place (eg, a museum in the illustrated example) as shown in FIG. Can be installed. At this time, if the back surface of each segment light emitter 1 is affixed to the floor surface with a double-sided tape or a sheet-like fastener, it can be easily removed and reused even when the passage is changed by an exhibit. Therefore, in addition to the art museum, the optimum guide lamp device A can be provided not only for the art museum but also for an event hall where the passage is frequently changed depending on exhibits. Of course, when the guide lamp device A is installed as a permanent facility, it is possible to provide the guide lamp device A as a low construction cost because no laying work such as burial is required.

When connecting the segment light emitters 1 so as to be orthogonal to each other at the corners, the segment light emitters 1 for corners provided with electrodes for + and − on both sides of the segment light emitters 1 are used. As described above, the guide lamp device A configured by connecting and arranging the plurality of segment light emitters 1 includes, as shown in FIG. 2, between the extraction electrodes 11a and 12a or 11b of the segment light emitter 1 disposed on one end side, A drive power supply unit 2 that causes the organic EL light emitting elements 10 of all the segment light emitters 1 to emit light by applying a DC voltage between 12b and a control unit 3 that controls the drive power supply unit 2 are provided. When the alarm information is received from the fire alarm device B, the control power source unit 2 is controlled by the control unit 3 and the power supplied to each segment light emitter 1 is turned on and off to flash the light emission state. Inform It is like that. The drive power supply unit 2 obtains a DC voltage from the commercial power supply AC.
(Embodiment 2)
By the way, although the light emission of the segment light emitters 1 constituting the guide lamp device A is collectively controlled in the above embodiment, in this embodiment, the light emission state for each segment light emitter 1 as shown in FIG. A light emission control unit 4 is mounted, and a control signal superimposed on a DC voltage supplied from the drive power supply unit 2 is sent from the control unit 3 to an address assigned to each light emission control unit 4 of each segment body 1. Each light emission control unit 4 is configured to control the light emission power supply to the organic EL light emitting element 10 via the switch element SW based on the control signal addressed to itself.

  In addition, as a method of sending a control signal from the control unit 3 to the light emission control unit 4 of each segment light emitter 1, it is not superposed on a DC voltage as described above. The control signal may be sent by a signal line that is wired. Further, the above-described scanning light emission can be performed by controlling the power supply from the drive power supply unit 2 separately, by supplying power from the power supply path wired separately from the drive power supply unit 2 to each segment light emitter 1. It may be realized.

  Next, a usage example of this embodiment will be described.

Example 1
This example is an example in which the guide light device A is used for evacuation guidance in the event of a fire. For example, it is assumed that the emergency light EX is installed at two places as shown in FIG. The segment light emitters 1 are connected and arranged so that both ends of the group of light emitters 1 are located near the respective emergency exits EX. On the other hand, the control unit 3 is provided with a function of determining an emergency exit EX that can be evacuated to a remote location without passing through the ignition location from the ignition location information included in the notification information transmitted from the fire alarm device B.

  Thus, when there is the alert information from the fire alarm device B, the control unit 3 determines which of the two emergency exits EX is used for evacuation based on the information of the fire location included in the alert information. Based on the determination, a control signal is superimposed on the DC power supply voltage supplied from the drive power supply unit 2 and transmitted to the light emission control unit 4 of each segment light emitter 1 so as to perform scanning light emission in the guiding direction. As a result, in each segment light emitter 1, the light emission control unit 4 controls the light emission power supply to the organic EL light emitting element 10, so that the entire guide lamp device A emits light so that the light emission position proceeds in the guide direction. As a result, the person is guided to the emergency exit EX, and can smoothly and safely retreat.

  When there are three or more emergency exits EX, the above-described corner segment light emitters 1 are arranged at branch points such as a T-junction to enable scanning light emission corresponding to each emergency exit. It becomes.

  Further, by using an organic EL light emitting element 10 of the segment light emitter 1 that can emit a plurality of colors, the light emission color at the normal time (for example, green) and the light emission color at the time of evacuation guidance (red) are made different. If you do, you can alert people.

Example 2
This example is an example in which the guide light device A is used for guidance guidance for smoothly exiting at a place where many people visit at an event venue or a museum, for example, as shown in FIG. The segment light emitters 1 are connected and arranged so that both ends of the group of light emitter segments 1 of the guide lamp apparatus A are located in the vicinity of the respective exits EX ′. On the other hand, the control unit 3 has a function of determining an exit E ′ that allows a person to leave smoothly based on monitoring information from a monitoring device C that monitors a crowded state of the person using a human sensor or a monitoring camera. The monitoring information may be, for example, a signal sent to instruct the exit EX ′ based on the judgment of the monitoring person monitoring the state.

  Thus, based on the monitoring information, the control unit 3 determines whether the retirement exit can be smoothly exited while avoiding congestion, and based on this determination, the light emission control of each segment light emitter 1 so as to perform scanning light emission in the guiding direction. The control signal is transmitted to the unit 4 while being superimposed on the DC power supply voltage supplied from the drive power supply unit 2.

  As a result, in each segment light emitter 1, the light emission control unit 4 controls the light emission power supply to the organic EL light emitting element 10, so that the entire guide lamp device A emits light so that the light emission position proceeds in the guide direction. As a result, the person is guided and guided to the exit EX 'where congestion can be avoided, so that the person can smoothly and safely exit.

  Even in this example, when there are three or more exits, the corner segment light emitter 1 as described above is arranged at a branch point such as a T-junction to correspond to each exit EX ′. Scanning light emission is possible.

In any of the above-described usage examples, a method of transmitting a control signal from the control unit 3 to the light emission control unit 4 by voltage superposition is employed. However, for example, wireless communication such as UWB (Ultra Wide Band) is used. You may make it transmit.
(Embodiment 3)
The guide light device A of the present embodiment is for guiding a visitor to a room (office) from reception of a floor of an office building or the like. For example, as shown in FIG. The segment light emitters 1 are connected to a plurality of branch passages X ′ branched from M and the main passage X to the position of each room Y, and guided to the room Y from the main passage X via the branch passage X ′. It is something that can be done. That is, the direction of guidance to the room Y corresponding to the branch path X ′ is indicated by a group of segment light emitters connected to each branch path X ′.

  Corresponding to the above-mentioned guidance guidance, as shown in FIG. 6B, the function of performing wired (or wireless) communication with the control unit 3 and the guidance direction corresponding to the room Y that the visitor wants to visit are selected. In order to do this, the input unit 5 having a selection button (not shown) associated with each room Y, the arrangement pattern of the group of light emitters 1 based on the guiding direction with respect to each branch passage X ′, and the room Y And a storage unit 6 for storing a table showing the correspondence relationship.

  The input unit 5 combines, for example, a display and a touch switch, and displays, for example, a department name of the room Y as an icon. When the visitor touches the department name icon, the input signal of the room Y is captured. Use what is.

  The control unit 3 has a function of communicating with the input unit 5, and reads out the arrangement pattern of the segment light emitters 1 in the corresponding branch passage X ′ from the storage unit 6 based on a selection signal from the input unit 5. And a function of controlling the drive power supply unit 4 so as to cause the group 1 segment 1 light emitters 1 corresponding to the arrangement pattern to scan and emit light.

  Thus, when the visitor selects a room Y that he / she wants to visit by the input unit 5 installed at the entrance of the floor, the selection signal is sent to the control unit 3, and the control unit 3 sends the selected room Y to the selected room Y. The arrangement pattern of the segment light emitters 1 indicating the corresponding guiding direction is read from the storage unit 6 and the group light emitters 1 of the branch passage X ′ corresponding to the arrangement pattern are scanned and emitted in the direction of guiding to the selected room Y. Control is performed through the drive power supply unit 4.

  on the other hand. The control unit 3 constantly scans and emits a group of segment light emitters in the main passage X in the normal direction to guide the visitors along the normal route.

  The visitor who selects the room Y by the input unit 5 is guided to the room Y by the scanning light emission of the segment light emitter 1 in the branch passage X ′. In this case, by changing the emission color of the segment light emitter 1 in the branch passage X ′ and the emission color of the segment light emitter 1 in the main passage X, the branch passage X ′ and the main passage X can be distinguished from each other, Make sure visitors do not get lost.

  The method for controlling the scanning light emission of the segment light emitter 1 is the same as that in the second embodiment, so that the description thereof is omitted.

  By the way, instead of the room Y, the present embodiment can be applied to a floor where a plurality of various windows such as a government office and a bank exist. In this case, the visitor selects at the input unit 5 is a window.

  In addition, the present embodiment can be applied to guide guidance to exhibits at museums and event venues where the number of visitors is limited. In this case, the visitor selects with the input unit 5 is an exhibit that the visitor wants to see.

  If a large number of visitors or visitors are predicted at a time, the location where the branch passage X 'guides and guides, exhibits, etc. are clearly indicated at the branch point between the main passage X and the branch passage X'. A guide plate may be provided as an auxiliary.
