The disaster prevention lighting tools (leading light, emergency lighting tool) regulated in the Fire Fighting Law and Building Standard Law aim at the light provided for unspecified multiple people so that they can evacuate quickly and safely upon a fire. However, a blackout of not only the building itself but in a whole area is not considered as well as the situation where the form of the routine evacuation path is changed abruptly. Further, it is only an exceptional number of local governmental bodies having experienced major tsunami disasters, such as Taro Town and Kainan Town, that installed street lights equipped with an emergency power supply (including solar system) for assurance and support of the safety of the evacuation path to the emergency refuge site. If a power outage occurs in a wide area at night due to an earthquake in a metropolis such as Tokyo and Osaka now, it is foreseen that there is a blackout at outdoor evacuation paths and refuge sites to hamper smooth evacuation actions. In the metropolitan areas, there are usually lots of temporal visitors and passers as well as local residents, and a visibility is necessary in a relatively wide area to guide these evacuees who are geographically strangers. To achieve the purpose, light emitting guide plates and maps showing refuge sites (parks, squares, schools, etc.) as well as lighting of the evacuation path are indispensable.
