Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a guide light that guides evacuees to an evacuation exit by illumination and sound in the event of an emergency such as a fire.

[Conventional technology]

In addition to guidance through lighting, speakers are also used,
Guidance lights that can guide people to evacuation exits by voice,
It is known from Utility Model Publication No. 52-25100 and Utility Model Publication No. 54-33838.

In Japanese Utility Model Publication No. 52-25100, the housing of the guide light is divided into two by a partition wall, one of the rooms is provided with an arrow display, and a speaker is built in, so that audio can be heard in the direction of one end of the housing. A guide light is described in which the above-mentioned speaker storage part is used as a unit and is connected to a housing with a permanent magnet so that an arrow display can be directed in at least one direction, left or right. .

Further, Japanese Utility Model Publication No. 54-33838 describes a guide light in which a buzzer unit with a built-in buzzer is detachably attached to at least one of the left and right ends of a lighting fixture body with a panel displaying an emergency exit.

[Problem that the invention seeks to solve]

However, with the technology of Utility Model Publication No. 52-25100,
Since the direction of the sound emitted by the speaker is toward the end face of the casing and toward the wall of the building, there was a problem that the induction effect was not good. This problem cannot be improved even with a technique in which a unit containing a built-in speaker or the like is attached to a permanent magnet housing. Moreover, despite the use of this unit, it can only be used when the arrow direction of the arrow display is in both directions or in one direction, and there is also the problem that it is poorly suited to the installation conditions of guide lights that can be installed in a wide variety of locations. Ta.

Also, the one described in Utility Model Publication No. 54-33838,
It is only suggested that it is possible to choose between one or two buzzer units, but there is no way to match the direction in which the sound is emitted to the guide light installation conditions. Moreover, depending on the connection structure of the unit to the panel-equipped lighting fixture main body, there is a problem that the overall strength of the guide light may be reduced.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a guide light that is strong, can improve the sound guidance effect, and is highly adaptable to various installation conditions.
