Abstract:
PROBLEM TO BE SOLVED: To provide an indicating lamp that can perform a stable escape guide over long time without making facilities large sized and that can secure a high sight recognition capability.
SOLUTION: A lamp 3 having a light source 25 with low power consumption and high brightness at the upper part of a pole 1 lights up the light source 25 by a battery. With this, it can inform of the neighbors by indicating a place of refuge in an emergency. Because the light source 25 consumes a low power, it can light a lamp for long time by the battery and bring a stable effect at the time of a stoppage of electric current. Because a plurality of high brightness LEDs are mounted with irradiation directions different from each other, the light source 25 can secure a high sight recognition capability in a wide range. Furthermore, by making an indication in higher position by mounting the lamp 3 into the upper part of the pole 1, it can make the escape guide of the inhabitants in wide area.
