  • Patent number: 5588738
    Abstract: A lantern including a battery power supply, a pair of fluorescent tubes, a normally open manually operable multi-position switch, a motion detector device with a normally open switch and an electric-powered horn. The switch operates to selectively connect the power supply with one or both of the tubes or with the motion detector. By operation of the multi-position switch, the motion detector selectively operates to connect the power supply with the pair of tubes, with the pair of tubes and the horn or with the horn when the switch thereof is closed in response to detected motion. The lantern further includes a light reflector selectively moveable from a stored position to an operating position where it reflects and concentrates light emitted by the tubes in a limited field of view adjacent a side of the lantern within which motion is to be detected by the motion detector.
