Description

Emergency exit guide device for firefighting using electric device of building}

The present invention relates to an emergency exit device for firefighting using an electrical device of a building, and more specifically, to an emergency exit in case of an emergency, in addition to the emergency exit guidance, a side direction indicator or the like to quickly evacuate evacuees to the exit direction. It relates to an emergency exit device for fire fighting using an electric device.

In general, there are emergency induction lights installed in buildings, and there are wall-mounting methods that are embedded in walls adjacent to emergency exits or walls of emergency stairs, and ceiling-induction emergency lights that are suspended from ceilings.

However, because the wall-mounted emergency induction lamp has a low installation height, there is a problem of poor visibility in an emergency situation, and the ceiling-mounted emergency induction lamp has a height of more than 2 meters, so people who evacuate in the state of fire and full of smoke Given the point of deceiving and moving this head, there is a problem of poor visibility.

In addition, wall-mounted emergency induction lamps and ceiling suspension-type emergency induction lamps have a problem in that it is difficult to check the location of the emergency induction lamp because the light from the emergency induction lamp is blurred when a fire occurs and the flame and smoke are full.

As a prior art, Republic of Korea Patent Publication No. 10-2003-0062177 (20030723 published) (hereinafter referred to as'prior art 1') is mounted on one side of the emergency light case, the laser portion for irradiating the laser beam, and the outer edge of the emergency light case Disclosed is an emergency exit guidance device using a laser including a light emitting body formed on a surface, a driving unit installed inside the emergency light case to drive a laser unit and a light emitting unit, and a reflector capable of changing a laser beam irradiated from the laser unit. .

However, the prior art 1 is simply an emergency light that irradiates a laser beam from one emergency light to the other and is equipped with a reflector to change the laser beam, so the laser beam can be identified in a smoke-filled situation, but the direction is There was a problem in that it could not be recognized at a glance and wasted time while wasting right and left.

In addition, as a conventional prior art, Republic of Korea Patent Publication No. 10-2016-0039397 (published 20140411) "guide sign with an emergency exit guidance function" (hereinafter referred to as'prior art 1'), the light emitting sheet mounted on the front of the frame, A light-shielding sheet mounted on the top of the light emitting sheet and the front of the frame, a light-shielding sheet with perforated emergency evacuation, a light-shielding sheet mounted on the top and the front of the frame, a guide sheet printed with a guide, a storage battery, and a sensing unit for detecting ambient light , Printed guide map is visually recognized in normal use, including a control unit that is connected to the storage battery and the sensing unit and controls signals to be supplied to the light emitting sheet by receiving signals from the sensing unit. In case of emergency, emergency evacuation perforated on the shading sheet Disclosed is a technique that allows visibility.

However, since the prior art 1 is directed to an emergency exit by a guide map, people evacuating in an emergency and embarrassing situation, such as a fire, have difficulty in checking and evacuating the guide map. As a result, evacuation time is delayed and human life is delayed. There was a problem that becomes larger.

In addition, as a conventional prior art, Republic of Korea Patent Publication No. 10-2003-0062177 (20030723 published) "Emergency exit guidance device using a laser" (hereinafter referred to as'prior art 2') is a rectangular emergency light case, and the inside of the emergency light case A laser unit mounted on one side and irradiating a laser beam, a light emitting body formed on an outer edge surface of the emergency light case to emit light, a driving unit installed inside the emergency light case to drive the laser part and the light emitting body, and the laser In order to change the laser beam irradiated from the part, including the reflector installed on the ceiling spaced apart from the emergency light case, it is difficult to secure a view by smoke in the event of a fire. Disclosed is a technology that makes it easy.

However, since the prior art 2 simply irradiates a laser beam and cannot give directions, evacuees can move to a blocked emergency exit, and only after evacuators reach a blocked emergency exit. As there is a need to find an emergency exit that is not blocked by turning, the unnecessary time is wasted in an urgent and embarrassing situation, and as a result, there is a problem that human life is increased.

Republic of Korea Patent Publication No. 10-2016-0039397 (2014.04.11) Republic of Korea Patent Publication No. 10-2003-0062177 (2003.07.23)
