(ゆうどうとう)

ゆうどうとう
noun
guide light; exit sign; emergency guidance light
building
1. guide light; exit sign — illuminated signs that show evacuation routes in buildings
Illuminated signs installed in buildings to show the direction of emergency exits and evacuation routes. In Japan they are legally required in most public buildings and typically show the familiar green running-figure pictogram. Also used more generally for any light that guides movement (e.g., runway lights, signal lights for ships).
Please evacuate following the arrows on the exit signs.
Exit signs stay lit for a while even during a power outage.
Building managers make sure not to place anything in front of the exit signs so as not to obstruct evacuation.

Compound of 誘導(ゆうどう) ('guiding; leading') and (とう) ('light; lamp'). Refers to any illuminated sign or lamp used to guide people or vehicles, with evacuation exit signs being by far the most common referent.

Usage

  • In Japan, 誘導灯(ゆうどうとう) is the standard regulatory term for the illuminated exit and evacuation-route signs required by the Fire Service Act (消防法(しょうぼうほう)).
  • Typical signs show either the green-background running-figure pictogram (避難口(ひなんぐち)誘導灯(ゆうどうとう)) or a directional arrow (通路(つうろ)誘導灯(ゆうどうとう)).
  • Also used in aviation (滑走路(かっそうろ)誘導灯(ゆうどうとう), 'runway guide lights') and maritime contexts.
