Description

  The present invention relates to a lighting device that turns on a plurality of lighting fixtures and guides a person to an exit in an emergency.

In recent years, facilities such as large-scale public facilities and large-scale underground malls have increased, and the evacuation route has become longer and more complicated in the event of an emergency. Crisis management of evacuation guide lights at the time of a disaster is becoming more important not only in such facilities where an unspecified number of people gather, but also in residences such as apartments.
Therefore, conventionally, a lighting control system is known in which a plurality of light emitters are sequentially turned on in time series to guide a person in the direction of the lighting order (see, for example, Patent Document 1).

As shown in FIG. 6, the lighting control system 100 described in Patent Document 1 includes a plurality of light emitting diode units 101 (101A, 101B,...), And a brightness sensor 102 that detects the brightness around the taxiway. And a control device 103 that controls lighting of the light emitting diode unit 101 in response to a detection signal of the brightness sensor 102.
The light emitting diode units 101 are arranged at predetermined intervals along the guide route for evacuation so as to be buried in the floor surface, and are connected to the control device 103 and the power source 104.

  When the control device 103 receives an alarm signal or the like from an alarm device or the like (not shown) connected to the lighting control system 100, the control device 103 lights the light emitting diode unit 101 with a predetermined lighting pattern. Each light emitting diode unit 101 is assigned an address number (here, 101A, 101B, 101C,..., 101F), and the control device 103 assigns each light emitting diode unit 101 corresponding to the address number. The person M is led to the exit by lighting with a predetermined lighting pattern.

Hereinafter, an illumination device according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the lighting device 10 according to the embodiment of the present invention normally includes a plurality of lighting fixtures 20 (20A, 20B, 20C,... 20E) that normally illuminate an illumination space 11 such as a passage or a hall. ).
In addition, suppose that the lighting fixture 20 nearest to the exit 12 of the lighting space 11 is shown with the lighting fixture 20E.

As shown in FIG. 2, each lighting fixture 20 is connected to a control device 30 and is controlled to be turned on and off.
The lighting fixture 20 includes a light source 21, a power supply circuit 22, a charging circuit 23, and the like. As the light source 21, an LED can be used. The power supply circuit 22 is connected to the commercial power supply 13 (see FIG. 3), and turns on the light source 21 based on a signal from the control device 30. In addition, a battery 24 as an emergency power source is connected to the charging circuit 23, and is always charged with power from a commercial power source.
Thereby, at the time of a power failure, supply of electric power from the battery 24 is received, and the lighting fixture 20 can be turned on.

  As shown in FIG. 3, the control device 30 is charged by the control unit 31 that controls the lighting of each lighting fixture 20, the charging circuit 32 connected to the commercial power supply 13, the charging circuit 32, and supplies power to the control unit 31 in an emergency. It has a battery 33 to be supplied, emergency detection means 34 for detecting an emergency, and the like.

When the fire alarm is activated, the emergency detection means 34 receives a signal notifying that a fire is emitted from the fire alarm and detects that a fire has occurred.
Alternatively, the fire alarm is not activated, but when a power failure occurs, the power supply is interrupted, so that the power failure is detected.

The control unit 31 normally operates the lighting fixtures 20A to 20E as normal lighting by lighting them in a normal state.
On the other hand, when it is detected by the signal from the emergency detection means 34 that it is an emergency, the lighting fixtures 20A to 20D are lit in an emergency way to guide the way to the exit 12, and the lighting fixture at the exit 12 20E flashes to indicate the location of exit 12.
In an emergency, it is desirable to turn on the lighting fixtures 20A to 20E brighter than the brightness during normal illumination.

Next, a lighting operation for guiding the way from the lighting device 20 to the exit 12 until the lighting device 20 is turned on will be described.
As shown in FIG. 4, the lighting fixtures 20A to 20E are turned on as normal lighting fixtures at the normal time.

Start.

  After a certain period of time, the next lighting fixture 20B starts to light. Further, after a certain time has elapsed, the next lighting fixture 20C starts to light. The lighting fixture 20D that is the second closest to the outlet 12 starts to turn on and lights for a certain period of time, then the lighting fixtures 20A to 20D are turned off, and the lighting fixture 20A starts to turn on again in the same manner. This is repeated thereafter.

As a result, lighting starts sequentially with a certain time delay toward the exit 12, and thus the start of lighting moves toward the exit 12.
During this time, the lighting fixture 20E closest to the outlet 12 repeats flashing at short intervals.

Alternatively, as shown in FIG. 5, when the lighting fixtures 20 </ b> A to 20 </ b> E are turned on as normal lighting fixtures and the emergency detection means 34 of the control device 30 detects that it is emergency, the outlet 12 (see FIG. 1). The lighting fixture 20A provided at the farthest position from the lighting) is turned on brighter than the normal lighting, and is turned off after a certain period of time. When the lighting fixture 20A is turned off, the next lighting fixture 20B is turned on and turned off after a predetermined time has elapsed. Further, when the lighting fixture 20B is turned off, the next lighting fixture 20C is turned on and turned off after a predetermined time has elapsed.
This is repeated thereafter.

Thereby, since the lighting fixture 20 lights sequentially toward the exit 12, blinking moves toward the exit 12.
During this time, the lighting fixture 20E closest to the outlet 12 repeats flashing at short intervals.

  As mentioned above, according to the illuminating device 10 of embodiment which concerns on this invention demonstrated, the illuminating device 10 has several lighting fixture 20A-20E, and is functioning as normal illumination at the time of normal. Further, in an emergency, the lighting fixtures 20A to 20D are lit up to guide the way to the exit 12, and the lighting fixture 20E closest to the exit 12 flashes at a short interval to notify the exit 12. It can respond to emergency evacuation guidance without installing lighting equipment.

  Moreover, according to the illuminating device 10 of embodiment which concerns on this invention, since the lighting fixtures 20A-20E are lit brighter than normal illumination in an emergency, it turns out that it is an emergency and can be induced | guided | derived clearly.
