Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a flashing guide light for guiding an evacuation route while indicating an emergency situation such as a power outage or a fire.

Technical Background and Problems Conventionally, this type of flashing guide light combines an internally illuminated flashing guide light that indicates an emergency situation by blinking and dimming the fluorescent light, a fluorescent light, and a xenon lamp. There are two types of guide lights: a combination flashing guide light that indicates an emergency situation.

First, with the former internal lighting type, when there is no fire signal and only a power outage occurs, the luminous flux is reduced to 36% compared to normal times.
%, and when there is a fire signal and there is no power outage, the luminous flux is switched between 100% and 36%, and when there is a fire signal and there is a power outage, the luminous flux is switched between 36% and 10%. Flashes.

In the latter combination type, when there is no fire signal and there is only a power outage, the fluorescent lamp lights up by 36% and the xenon lamp does not blink. And when there is a fire signal and there is no power outage, the fluorescent lights are turned off.
The xenon lamp blinks at 100% lighting. moreover,
When there is a fire signal and there is also a power outage, the fluorescent lights are lit at 36% and the xenon lamps flash.

In this way, both types have the function of displaying multiple emergency conditions,
It is necessary to check whether such functions function normally. Therefore, in conventional devices, a plurality of check switches are provided to turn off the power or give a fire signal.
Therefore, it is necessary to install a plurality of inspection switches, and there are also a plurality of operating sections, which makes the manufacture of the instrument cumbersome.

OBJECTS OF THE INVENTION An object of the present invention is to obtain a blinking guide light that can operate in a plurality of emergency states by operating a single operating section.

SUMMARY OF THE INVENTION The present invention provides a flashing guide light that is connected to a commercial power source and a fire detector and is equipped with a display unit that indicates an emergency situation such as a power outage or a fire by blinking or dimming the indicator light.

A battery 16 is connected with a battery 16 interposed therebetween. Further, the Xe flashing unit 14 is connected via the inspection switch 12 to a signal terminal 17 to which a fire detector (not shown) is connected.

Therefore, the inspection switch 12 is an integrated structure with a three-stage rotary switching section 18 on the fluorescent lamp 3 side and a three-stage rotary switching section 19 on the xenon lamp 5 side, and each movable Contact 2
0 and 21 are formed so as to be rotated simultaneously by the drawstring 7.

In such a configuration, when the inspection switch 12 is in the state shown in FIG. 2, it is in a normal state, the fluorescent lamp 3 is lit with 100% luminous flux, and the xenon lamp 5 is not lit.

When the drawstring 7 is pulled in this state, the movable contacts 20 and 21
rotates one step clockwise and becomes the first step of inspection.
At this time, the rotary switching unit 18 is turned off, resulting in a power outage state, but the other rotary switching unit 1
9 is ON and there is no fire signal. Therefore, the fluorescent lamp 3 is lit with a luminous flux of 36% by the power of the battery 10, and the xenon lamp 5 is not lit.

Next, when you pull the drawstring 7 again, the movable contact 2
0 and 21 are further rotated one step clockwise and inspected 2.
It becomes a stage. At this time, the rotary switching section 18
Since it is turned on, the power outage has been resolved, and the fluorescent lamp 3 is lit with 100% luminous flux by the commercial power supply 13. Moreover, the other rotary switching section 19 is
This means that the power is off and a fire signal has been set.
The xenon lamp 5 blinks. Thereby, the operation of the xenon lamp 5 is inspected.

Further, if the pull cord 7 is pulled, the state of the inspection switch 12 becomes as shown in FIG. 2, and becomes the normal state. In this way, every time you pull the drawstring 7, check the check switch 1.
The switching state of the switch 2 changes, and this state is displayed by the indicator 6, for example, by changing the color.

Next, a second embodiment of the present invention will be explained based on FIG. First, a fluorescent lamp 23 as an indicator light is connected to the lighting unit 22, and a battery 25 is connected via a connector 24.
