DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of the guide light according to the first embodiment of the present invention. The guide light of the present embodiment is the same as the guide light shown in FIG.
The brightness sensor 5 is added. Brightness sensor 5
Is for detecting ambient brightness. The variable display panel 10 can switch and display a plurality of display contents (designs), and this switching is controlled by the control unit 2. During non-emergency situations such as power outages, fires, earthquakes, etc. (normal times), switching between advertisements and elevator direction display and evacuation guidance displays are performed as appropriate, and priority is given to evacuation guidance directions during power outages, fires, earthquakes, etc. To do it.

Here, the variable display panel 1 by the control unit 2
The switching of 0 is performed in consideration of information on the surrounding brightness from the brightness sensor 5. In other words, in a state where power is supplied from the commercial power supply 3 (at a normal time), when the surroundings are bright, it can be determined that there is no danger and the situation is relatively safe. , A higher percentage of display, such as advertising or elevator direction indications (e.g.,
4: 1), and in a state where power is supplied from the commercial power supply 3 and the surroundings are dark, the ratio of displaying other than the evacuation guidance is set to a low ratio (for example, 1: 1).

According to the present embodiment, during non-emergency times (normal times), not only displays other than evacuation guidance such as advertisements and directions of elevators can be displayed, but also evacuation guidance can be displayed. A learning effect can be expected by displaying the direction. Also, in an emergency, the evacuation guidance direction is preferentially displayed, so that the emergency guidance effect is not reduced. Further, since one display panel performs both the display of the evacuation guidance direction and the display other than the evacuation guidance,
Useful displays other than evacuation guidance can be performed in a limited space.

Also, it is determined whether or not the vehicle is in a safe condition based on the surrounding brightness information from the brightness sensor 5. If it is determined that the vehicle is relatively safe based on the result of the determination, an evacuation guide is provided. The timing of switching between the display of the evacuation guidance direction and the display other than the evacuation guidance in non-emergency situations (normal times) is changed, such as by increasing the display time of other displays. Effective display can be performed.

FIG. 2 is a block diagram showing a schematic configuration of a guide light according to a second embodiment of the present invention. In this embodiment,
In the first embodiment, a human body sensor 6 is added instead of the brightness sensor 5. The human body sensor 6 detects the number of people existing around. In the present embodiment, switching of the variable display panel 10 by the control unit 2 is performed in consideration of the number of people information from the human body sensor 6.
In other words, in a state where power is supplied from the commercial power supply 3,
If it can be determined that there are many people around, it can be determined that there is no danger and it is relatively safe.Therefore, the ratio of performing displays other than evacuation guidance, for example, displaying advertisements and elevator directions, etc., should be increased. (For example, 4: 1) and the commercial power supply 3
If it can be determined that there are few people around in a state where power is being supplied from, the ratio of displaying other than evacuation guidance is set to a low ratio (for example, 1: 1). Further, when it can be determined that there is no person, control such as stopping only the evacuation guidance display or the like can be performed. Further, when the commercial power source 3 loses power, only the evacuation guidance display is performed using the emergency power source 4.

According to this embodiment, when there is a person around, display other than evacuation guidance is also performed, so that a lot of information including the evacuation guidance display can be provided, and the display space can be used effectively.

FIG. 3 is a block diagram showing a schematic configuration of a guide light according to a third embodiment of the present invention. In this embodiment,
In the first embodiment, a smoke sensor 7 is added instead of the brightness sensor 5. The smoke sensor 7 detects surrounding smoke. In the present embodiment, switching of the variable display panel 10 by the control unit 2 is performed in consideration of smoke information from the smoke sensor 7. In other words, when it is determined that there is no or little smoke in a state where power is supplied from the commercial power supply 3, it can be determined that there is no danger and the situation is relatively safe. For example, if the ratio of displaying advertisements and directions of elevators is increased (for example, 4: 1), and it is determined that there is a lot of smoke in a state where power is supplied from the commercial power supply 3, evacuation is performed. The ratio of displaying other than guidance is reduced (for example, 1: 1) or only evacuation guidance is displayed. Further, when the commercial power source 3 loses power, only the evacuation guidance display is performed using the emergency power source 4.

According to the present embodiment, the effect of learning the evacuation direction in the event of a fire or the like can be enhanced, and the evacuation direction can be reliably guided even in the case of a fire or the like.

FIG. 4 is a block diagram showing a schematic configuration of a guide light according to a fourth embodiment of the present invention. In this embodiment,
In the first embodiment, a temperature sensor 8 is added instead of the brightness sensor 5. The temperature sensor 8 detects an ambient temperature. In the present embodiment, the switching of the variable display panel 10 by the control unit 2 is performed in consideration of the temperature information from the temperature sensor 8. In other words, when the power is supplied from the commercial power supply 3 and the temperature is low (approximately less than 30 ° C.), it can be determined that there is no danger and the situation is relatively safe. For example, if the ratio of displaying an advertisement or a direction display of an elevator or the like is increased (for example, 4: 1) and the temperature is high (approximately 30 ° C. or higher) in a state where power is supplied from the commercial power supply 3. If it can be determined, there is a risk of fire, etc.
The ratio of performing displays other than evacuation guidance is low (for example, 1:
1) Yes. Further, when the temperature becomes high (80 ° C.) and it is predicted that a fire has occurred, display other than evacuation guidance is not performed and only evacuation guidance display is performed. Further, when the commercial power source 3 loses power, only the evacuation guidance display is performed using the emergency power source 4.

According to this embodiment, the effect of learning the evacuation direction when a fire is likely to occur can be enhanced, and even if a fire occurs, the evacuation direction can be reliably guided.

It is to be noted that a humidity sensor is provided in place of the temperature sensor 8 to increase the ratio of displaying other than evacuation guidance when the humidity is high, and to increase the ratio of displaying other than evacuation guidance when the humidity is low. It is also possible to perform control to lower the value.

The ratio between the display other than the evacuation guidance and the evacuation guidance display may be changed stepwise by a certain threshold, or may be continuously changed by a function based on the value of each sensor.

FIG. 5 is a block diagram showing a schematic configuration of a guide light according to a fifth embodiment of the present invention. In this embodiment,
In the first embodiment, a clock 9 is added instead of the brightness sensor 5, and the variable display panel 10 is switched by the control unit 2 according to the time zone.
In other words, in a state where power is supplied from the commercial power supply 3,
In a time zone when it is considered that there are many people (generally from 6:00 am to 9:00 pm), it can be determined that there is no danger and the situation is relatively safe. Therefore, displays other than evacuation guidance, for example, advertisements and elevators In the state where power is supplied from the commercial power supply 3 and the number of persons is considered to be small (roughly from 9:00 pm to 6 am ), The security is low,
The ratio of performing displays other than evacuation guidance is low (for example, 1:
1) Yes. Further, during a time period such as midnight where it can be determined that there are no people (approximately from 11:00 pm to 4:00 am), control such as performing only the evacuation guidance display or stopping all displays can be performed. . Further, when the commercial power source 3 loses power, only the evacuation guidance display is performed using the emergency power source 4.

According to the present embodiment, in a relatively safe time zone where there are many people, the display ratio other than evacuation guidance is high, and the display space can be used effectively. Also,
By stopping the display when it seems that no one is present, energy can be saved.

In the above embodiment, means for changing the display ratio between the display other than the evacuation guidance and the evacuation guidance display include, for example, time division and screen division.

As shown in FIG. 6, the time division method
The evacuation guidance display 11, the toilet display 12, the elevator display 13, and the text news 14 are sequentially displayed on one display surface. Each display time is set to 5 seconds, and the display is performed in order of evacuation guidance display → toilet display → elevator display → text news → evacuation guidance display... In addition, each display time is set to 1 according to the display content.
Seconds, five seconds, one minute, etc. may be changed.

As shown in FIG. 7, the screen division is performed on one display surface to provide an evacuation guidance display 11 and a toilet display 12.
, The elevator display 13 and the character news 14 are displayed at the same time. In other words, the four display contents are
The screen is divided into four parts and displayed on one display surface. The screen may be divided equally, as shown in FIG. 7, may be divided arbitrarily according to the display content, or may be any number other than four.

As for the evacuation guidance display, a display indicating the evacuation direction is performed as shown in FIG. That is,
By performing display using the section closest to the guidance direction among the sections divided on the screen, a better guidance effect can be obtained.
