<p>PURPOSE: To provide an emergency safety light lighted by detecting a C sound generated by a man and a shake due to an earthquake only in the case of the dark, by assembling a photo sensor, microphone, shake detecting sensor, etc. CONSTITUTION: A photosensor 18 detects the periphery for whether less than prescribed luminous energy or not. A resonance friction sound generated by a man is received by a microphone 14, to detect a shake due to an earthquake by a shape detecting sensor 15. When received a resonance friction sound or when detected a shake with received luminous energy of the photosensor 18 less than prescribed luminous energy, a switching element is turned on in a control circuit, to feed power to an electric emitter 12, and to light it put out after a prescribed time. Further, light part cases 1, 2 are left as fitted mountably/demountably to a holder case part 9 by a jack 17 and by a plug 19, to be put out in the case of insert connection and to be lighted in the case of separation. Also on/off lighting the detached light part cases 1, 2 can be performed by a manually operated switch 16.</p> |
