Description

[Detailed Description of the Invention] This invention relates to a lighting device for displaying the position of a fire extinguisher.

Hotel. factory. It is a good practice to always keep a fire extinguisher in your home. However, when a fire breaks out at night, it is often impossible to find a fire extinguisher, which may impede initial firefighting efforts.

The purpose of this idea is to indicate the location of fire extinguishers in the event of a fire.

This invention is characterized in that a lighting fixture with a fire extinguisher-shaped exterior is placed near the fire extinguisher, and the lighting inside the lighting fixture is turned on when a fire occurs.

An embodiment of this invention will be described with reference to the drawings. 1 is a lighting fixture with a fire extinguisher-shaped exterior, and its size is equal to or smaller than an actual fire extinguisher,
2 is an actual fire extinguisher. Lighting equipment 1 is fire extinguisher 2
is placed near. In the illustrated example, the fire extinguisher 2 is placed on a shelf 3 provided above it.

The lighting fixture 1 is partially or entirely translucent, and specifically is formed by molding a translucent resin. If necessary, a fire extinguisher or a sign indicating the presence of a fire extinguisher may be attached to the surrounding surface. Inside the lighting fixture 1, a lighting lamp such as a fluorescent lamp is housed, and a lighting device for lighting the fluorescent lamp in the event of a fire is housed.

FIG. 2 shows an example of this lighting device. 4 is the aforementioned fluorescent lamp; 5 is a high-frequency inverter circuit (a circuit that converts DC voltage to high-frequency voltage); 6 is a DC power source such as a battery that supplies DC voltage to the high-frequency inverter 5; and 7 is the DC power source 6 and the high-frequency inverter 5.
This relay has a contact 8 inserted between the two and is energized by a commercial power source 9. Normally, the relay 7 is energized by the commercial power supply 9 and its contacts 8 are open, but when a fire occurs and the commercial power supply is interrupted, the relay 7 returns to normal and the contacts 8 close. . This connects the high frequency inverter 5 and the DC power source 6, and the high frequency inverter 5 converts the DC voltage of the DC power source 6 into a high frequency voltage and applies it to the fluorescent lamp 4. The fluorescent lamp 4 is thereby turned on.

In the configuration shown in the figure, when the commercial power supply fails, contact 8
However, instead of this, the contact 8 may be closed by the operation of a fire alarm. Normally, when a fire alarm is activated, an emergency bell or the like is sounded, but it is also possible to use a contact that is closed at the same time as the contact that is closed for the sound. Furthermore, when the lighting device 1 is housed together with the DC power supply 6 in the lighting fixture 1 as shown in Fig. 2, the fluorescent lamp 4 can continue to be lit even after the commercial power supply 9 is out of power. When the fluorescent lamp 4 is to be lit by the operation of a fire alarm, the lighting device does not consist of a high frequency inverter circuit 5 and a DC power source 6, but is a lighting device that is powered by a normal commercial power source. You can.

In the above configuration, if a fire breaks out, the fluorescent lamp 4 is turned on when the commercial power supply is interrupted or the fire alarm is activated. This makes the lighting fixture 1 brighter, but since the lighting fixture 1 has the same external shape as a fire extinguisher, even if the surroundings are dark, it is obvious at first glance that the fire extinguisher 2 is installed nearby. You will be able to understand it immediately. Therefore, the fire extinguisher 2 can be easily found and used effectively for fire extinguishing activities.

As detailed above, according to this invention, a lighting fixture with the same external shape as a fire extinguisher is installed near the fire extinguisher, and the internal lighting light is turned on in the event of a fire, so even if the surrounding area is dark, However, the location of fire extinguishers can be easily understood, and the fire extinguishers can therefore be used effectively for firefighting activities.
