Description

  The present invention relates to a local illuminator group in which small illuminating devices having a power backup function are connected by communication and a network system thereof.

In today's sophisticated urban functions, lighting needs to be installed and operated as a purposeful system rather than just a light source. A considerable amount of power is expected to be turned on at night for security purposes, especially in underground shopping malls and large buildings with complicated passages. For this reason, if thinning lighting is performed for the purpose of suppressing the use of electric power, brightness is uneven and blind spots are generated. In addition, at construction sites, etc., lighting is necessary for display and guidance of dangerous places. In addition, an illuminating lamp is required for evacuation guidance in the event of a disaster. In addition, even if the building collapses due to an earthquake or the like, if the power supply is continued, the survivors will be reassured.
As described above, there is a need for a lighting device that can always function as an illuminating lamp when a trouble occurs in a place where trouble is likely to occur. An example of responding to the above request is “Patent Document 1”, which differs from the present invention in configuration and the like.
JP-A-2005-32115 (FIG. 1 etc.)

  If the passages and the like can be illuminated lightly as a whole by arranging weak light that secures the visibility of the feet at regular intervals, it is possible to prevent the occurrence of blind spots due to strong light and blind spots due to insufficient brightness. Further, even if the object jumps out into the dark outdoors due to tracking or the like, the brightness of the eye is low, so that the eye glow does not fully open, and loss of the target can be prevented.

  Also, at construction sites where the situation changes constantly, the danger location display is used for illumination as well as for guidance. Especially when working in dark places such as nighttime construction or underground or in buildings, the entire construction site should be illuminated by a powerful floodlight. The passage is secured by a light bulb suspended from above at a certain distance from the top, and a particularly dangerous place uses a light emitting band in which small light bulbs that emit red light are arranged in a string, By placing it at both ends of the road, it will illuminate your feet without being obstructed by luggage and people, and display dangerous areas by turning red light simultaneously with white, and light the parallel passages in green against the inclined passages, etc. It is extremely safe and convenient if guidance and display can be performed.

  In addition, it is necessary to secure evacuation guidance and visibility during evacuation. Conventional emergency lights and evacuation indicator lights are installed near the ceiling, but in the case of a fire, black smoke is trapped in a place more than 1 meter above the floor, and most of the light cannot be confirmed. However, the field of view can be secured basically at a position of about 1 meter above the floor, which is an evacuation space, attached to the floor and side walls near the floor. By control from the outside, for example, the right end of the light sources arranged horizontally can be emitted in red and the left end can be emitted in green and guided to the left side. Or, by shifting the timing of turning on and off individually, you can run the light spot and know the evacuation direction, you can change this according to the situation with the communication function, if the communication function is paralyzed, whether to keep that state It is extremely convenient if a preset operation can be performed and it is possible to operate independently for a certain time even when the power supply is cut off.

  Even if a building collapses due to an earthquake or the like, it is useful for escape and rescue of survivors if it is installed on a wall where a lot of viable space is generated. Survivors can check the surrounding situation by searching for a place where they can escape by operating for a certain period of time even if the power supply is cut off. Can be specified.
