Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides that the first illumination signal is turned on at normal times, the first illumination signal is turned on, and -11 is turned on at all times, that is, when there is an abnormality or a power outage, the first illumination signal is turned on and off. It is suitable for a guidance light device that can be installed in a movie theater.

Originally, the guide light system uses its built-in lighting with a total illumination height of 1'-1'.
, to increase the brightness of the guide light sign board, and display the guide light sign board to familiar people or people in the room by 3μ' +Jk +i'
L, there is something to let you know the exit in case of an emergency. Tokorakata and Sue said that if the brightness of the sign board of the guide light installed in movie theaters etc. is high, it will interfere with the movie viewing J1 and also spoil the atmosphere. You need to lower the brightness. However, in the event of an emergency, it is necessary to increase the brightness of the guide light sign board so that passersby or occupants can recognize the guide light sign board. That is, it is desirable that switching from dimmed lighting to full brightness lighting be performed not only during a power outage, but also when an abnormal condition occurs such as when an emergency bell rings or when a fire alarm occurs, that is, at the same time as when an abnormality occurs.

In order to address these needs, Japanese Utility Model Application Publication No. 47-27584 discloses that the first illumination light is used for C and M hours, the first illumination lamp is used for health T illumination, and the first illumination lamp is used for emergency purposes. a second illumination lamp illuminating at a second illumination level higher than the first illumination level;
, an operation relay device (emergency relay) for switching the second lighting level is provided in the emergency lighting equipment, and the operation relay device is activated by a transmitter activated by the operation of the fire alarm device in the event of an abnormality. A free induction device for switching the first illumination level to the second illumination level has been proposed.
, there is work.

However, there are problems when operating the operation relay using commercial power.

In other words, it is usually a fire alarm device as a transmitter, and whether this device is equipped with an alarm switch for transmitting the alarm, or if this existing alarm switch (designed for J-hunting low voltage) is used for commercial purposes. The power supply cannot be connected, and the alarm control relay cannot be activated directly using the existing transmitter.Also, if the transmitter is equipped with an alarm switch that can be connected to a commercial power source, and the commercial power source is connected to this, the low voltage circuit Designed transfer 11φ
A high-voltage power supply is drawn into the device, which means that low-voltage circuits and high-voltage circuits are mixed in, making it difficult to handle (1) and undesirable.

In order to deal with the problem of ,-, it is necessary to check whether the connection between the transmitter or IJ device and the operation relay is correct using a low current circuit, or whether the length of the connection between the transmitter and the 1M relay is correct. If it gets too long, the ℃ operation relay will not work properly due to this connection wire, and the voltage drop due to the connection will affect the circuit operation. . Especially l1t
- Control multiple emergency devices using the transmitter,
In this case, the distance between each emergency lighting device and the transmitter is different, and the length of the connection lead is also different, so the operation is secant.
If something doesn't work properly or something doesn't work properly, you can reliably control metalwork emergency lighting equipment.

In addition, since connection leads are usually wired over long distances, there is a high possibility that external factors such as earthquakes and fires may cause short circuits or short circuits.In the event of such short circuits or disconnection accidents, emergency lighting equipment may be If you continue fishing at a low lighting level, the original function of the emergency lighting equipment to guide fishing in an emergency will not be fully demonstrated, which will pose a danger to disaster prevention.

The present invention has been made to solve the problems listed in L-4, and embodiments of the present invention will be described below with reference to the drawings.
