Description

  The present invention relates to an emergency lighting fixture.

  Conventionally, there has been provided an emergency lighting fixture that is attached to a ceiling and lights up in the event of a power failure (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-340606

  In the event of a fire, smoke often stays near the ceiling, so it is difficult to ensure visibility with the emergency lighting fixtures attached to the ceiling as described above.

  This invention is made | formed in view of the said reason, The objective is to provide the emergency lighting fixture which is easy to ensure visibility even at the time of fire outbreak.

The emergency lighting apparatus of the present invention includes a plurality of light sources, a light source holder that holds each of the light sources, and an opaque plate material on which the light source holder is fixed on one side and the other side forms part of the wall surface. closing the decorative board having window holes through which light is provided with a plurality of pre-Symbol light source, said plurality of windows hole of the decorative plate made of a material to pass the plurality of optical sources light corresponding Do Ri and at least one window member is configured to be embedded disposed in embedding holes provided in the wall material in the near with the floor surface, each of said plurality of light sources, lenses to enhance the directivity Is an integrated light emitting diode .

  In the emergency lighting apparatus described above, each of the window bodies is preferably colored and has the same color as the decorative board.

  In the emergency lighting apparatus described above, it is desirable to include a plurality of the light sources connected in series or in parallel.

  According to the present invention, compared with the case where it is arranged on a ceiling surface or a wall surface in the vicinity of the ceiling surface, it is difficult for the visibility to be reduced due to smoke at the time of a fire, and the illuminance on the floor surface is easily increased.

It is sectional drawing in the horizontal cross section which shows embodiment of this invention. It is explanatory drawing which shows the position where the same is attached.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, an emergency lighting apparatus 1 according to this embodiment includes a plurality of (three in FIG. 1) electrical light sources 2, a light source holder 3 that holds each light source 2, and one surface side. At least one window hole 40 through which light from the light source 2 passes is made of an opaque plate material whose light source holder 3 is fixed (upper side in FIG. 1) and whose other side (lower side in FIG. 1) forms part of the wall surface. (In the figure, a total of three for each light source 1) provided with a decorative plate 4 and a window body 5 made of a material that allows light from the light source 2 to pass through and closing each window hole 40 of the decorative plate 4. Specifically, the emergency lighting fixture 1 is embedded in the embedded hole 60 provided in the wall material 6 with the window hole 40 oriented in the horizontal direction.

  A known light emitting diode can be used as the light source 2. The light source 2 may be an incandescent lamp such as a miniature light bulb or a discharge lamp, but it is desirable to use a light emitting diode as described above in order to reduce power consumption and size. Further, since the light emitting diode has a relatively small light emitting area, if the light emitting diode is used as the light source 2 as described above, the window hole 40 can be made relatively small to make it less noticeable. Furthermore, if a light emitting diode with a high directivity with an integrated lens is used as the light source 2, high illuminance can be obtained in a narrow range.

  Each light source 2 is connected to a lighting circuit (not shown). This lighting circuit lights each light source 2 using a battery (not shown) as a power source in the event of a power failure. For example, if the light source 2 is a light emitting diode, the lighting circuit can be realized by using a well-known stabilization circuit, for example. Description is omitted. Each light source 2 is connected in series or parallel to each other, for example, between the output ends of the lighting circuit. Moreover, a well-known secondary battery can be used as said battery. Furthermore, you may provide the suitable charging circuit which supplies electric power from a commercial power source before a power failure, and charges said secondary battery. Moreover, said lighting circuit and battery may be provided for every emergency lighting fixture 1, and a plurality of emergency lighting fixtures 1 may be connected to one lighting circuit or battery. When a lighting circuit or a battery is provided for each emergency lighting device 1, there is an advantage that malfunction due to disconnection or the like hardly occurs, and a plurality of emergency lighting devices 1 are connected to one lighting circuit or battery. In this case, there is an advantage that the individual emergency lighting apparatus 1 can be downsized.

  The light source holder 3 is merely a structural material, and can be configured by appropriately combining, for example, an insulating material such as a synthetic resin for insulation and a metal material such as aluminum for heat dissipation of the light source 2.

  The decorative board 4 is preferably made of the same material as the wall material 6 constituting the other part of the wall surface 61 or a material having a similar texture.

  As a material of the window body 5, for example, an acrylic resin or a polycarbonate resin can be used. In the example of FIG. 1, all the window holes 40 are closed by one window body 5 interposed between the decorative plate 4 and the light source holder 3. For example, one window body is provided for each window hole 40. A plurality of window bodies 5 may be provided such that 5 is provided. If the window body 5 is colored and has the same color as the decorative board 4, the window hole 40 and the window body 5 can be made less noticeable and the appearance can be improved as compared with the case where the window body 5 is colorless and transparent. .

  Here, the emergency lighting apparatus 1 is arranged at an appropriate interval at the lower end of the wall surface 61 (that is, near the floor surface 62) as shown by hatching in FIG. 2, and each light source 2 irradiates the floor surface 62 with light. .

  According to the said structure, compared with the case where the emergency lighting fixture 1 is arrange | positioned on the ceiling surface 63 or the wall surface 61 near the ceiling surface 63, the fall of visibility by the smoke at the time of fire occurrence does not occur easily, and floor surface It is easy to increase the illumination intensity of 62.
