PURPOSE: An emergency light is provided to guide a user to a safe zone by controlling the brightness and the rotation of the light. CONSTITUTION: A first user operating unit(10) includes a first emergency switch and a first light emitting unit. The first light emitting unit emits the light of a first specific wavelength corresponding to the closure of the first emergency switch. A second user operating unit includes a second emergency switch and a second light emitting unit. The second light emitting unit emits the light of a second specific wavelength corresponding to the closure of the first emergency switch. A first light transmissive filter(205) transmits the light of the first specific wavelength. A second light transmissive filter transmits the light of the second specific wavelength. A light driver(209) turns on and off the light according to the light control signal. |
