DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An illumination display system and an evacuation guidance system according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of an evacuation guidance system, and FIGS. 2 to 3 show block structures of a control unit and a parent unit.

In these figures, when the control unit 3 in the control unit 2 receives a notification from the notification device 1 such as an automatic fire notification facility for detecting a fire or the like that generates a notification or the like, this control unit 3 Sends a control signal to the corresponding parent unit 5 that manages the light emitting unit 4 at the transfer occurrence location via the transmission unit 6.

Here, the notification means a warning signal such as a fire, a gas leak, an earthquake, or a signal such as a control signal issued for guiding a person, for example.

Further, an individual address is assigned in advance to each parent unit 5 connected to the control unit 2, and the parent unit 5 is constructed so as to be able to receive the control signal addressed to itself. In each parent unit 5,
When this control signal is taken in by the control unit 8 via the transmission unit 7, a pattern corresponding to a blinking traveling pattern for safely guiding a person is discriminated from the control signal, and the light emitting unit 4 whose installation location is predetermined is determined. Is configured to be supplied with a lighting power for driving to light through the power supply line 9.

Here, the control unit 8 for discriminating the pattern is
As shown in FIG. 4, the nonvolatile memory 10 in which a plurality of pattern information such as a lighting order corresponding to a control signal and a lighting speed is stored is configured to be accessible. The pattern information and the input control signal are collated to read the corresponding lighting sequence and lighting speed.

The lighting order data indicates the lighting order of each light emitting unit 4 for forming a blinking traveling pattern by a plurality of light emitting units 4 grouped to guide a person in a safe direction. In the example illustrated in FIG. 5, the light emitting units 4 provided at the installation locations 1 to 5 are sequentially illuminated endlessly from 1 to 5. Further, the lighting speed is a blinking cycle, in other words, one lighting allocation time, for example, 6
The time of 0 ms is set.

Further, the power source section 11 of the parent unit 5 generates a DC power source of, for example, 12 V from a commercial AC power source, and power is supplied from the battery 12 at the time of power failure. The high-frequency power supply generation circuit 13 connected to the power supply unit 11 converts a DC voltage into a high-frequency voltage, and its output is connected to a light source control device 14 including switch means such as a relay unit. The light source control device 14 turns on / off the lighting power supplied to the light source such as a fluorescent lamp built in each light emitting unit 4 by the output of the control unit 8 which performs pattern discrimination.

Therefore, when the control unit 8 reads out the lighting sequence and lighting speed corresponding to the control signal sent from the control unit 2, a plurality of units connected to the parent unit 5 are read according to the discriminated pattern. Lighting power is sequentially supplied to the light emitting units 4, and, for example, in the above example, the light emitting units 4 provided in the installation locations 1 to 5 are installed.
Blinks repeatedly in a cycle of 60 ms to form a blinking traveling pattern capable of safely guiding a person from a fire occurrence place or the like.

According to such an embodiment, the parent unit 5 to which the plurality of light emitting units 4 are connected can collectively determine the pattern, and moreover, the lighting power is collectively supplied to the plurality of light emitting units 4. Therefore, it is not necessary to provide the plurality of light emitting units 4 with the control unit 8, the non-volatile memory 10, and the high frequency power supply generation circuit 13, which are pattern determining means, respectively. Can be simplified.

In the above embodiment, the light source control device uses the relay unit to turn on and off the power, but the light source control is performed by using a well-known power adjustment device such as a power transistor. The device may be configured.

Also, the light source is housed in the parent unit,
Not only the light emitting unit but also a blinking traveling pattern including the parent unit may be formed. Furthermore, in addition to the fluorescent lamp described in the above embodiment as the light source,
Various light sources such as a halogen bulb can be applied.

In the above, the use of the evacuation guidance system for guiding a person when a fire or the like occurs is specifically described, but the present system can be applied according to other uses, for example, It is possible to configure an illumination display system such as various electronic display devices that guide the transportation route of articles and the like, and electronic decoration devices that perform visual effect display according to the surrounding environment.

[0024]

As described above, according to the present invention, a parent unit to which a plurality of light emitting units are connected can collectively determine a pattern, and moreover, a lighting power is supplied to the plurality of light emitting units. Since it is possible to supply all at once, it is not necessary to provide a pattern determining means or a lighting control circuit for each of the plurality of light emitting units.
The structure of the light emitting unit can be simplified.
