Abstract

A light powered rotating detection mirror includes a detection mirror formed of two back-to-back convex mirrors; a motor having a rotatable shaft from which the detection mirror is supported by a first interconnecting chain; a housing and a second interconnecting chain for supporting the motor from a ceiling; a sleeve positioned in surrounding relation to a fluorescent bulb; a solar cell positioned between the sleeve and the fluorescent bulb for converting light energy to electrical energy; and electrical wires connecting the solar cell to the motor for actuating the motor to rotate the detection mirror.
