Solar power-operated construction work warning lamp

Claim 1

A solar power-operated construction work warning lamp comprising: a top cover, said top cover being made from a transparent material having a top surface curving outwards; a lamp guard, said lamp guard being made from a hollow transparent cylinder having a top opening covered by said top cover, a plurality of openings equidistantly spaced around a peripheral wall thereof and respectively covered with a plurality of reflectors, and a plurality of fastening holes around a peripheral bottom edge thereof; a solar cell assembly, said solar cell assembly comprised of a flat base board having a plurality of solar cells on a top edge thereof disposed inside said lamp guard below said top cover, and a loop flange on a bottom edge thereof; a column formed by connecting two symmetrical parts together with a plurality of light emitting elements mounted thereon, said column being secured to said loop flange at the bottom, and having holes around a bottom flange thereof; a base made in a cylindrical shape having one end opened and an opposite end closed by a cover board, said base having a plurality of holes around a top ring thereof respectively connected to the fastening holes on the peripheral bottom edge of said lamp guard, said cover board having a plurality of top tenons and holes respectively connected to the holes on the bottom flange of said column permitting said column to be supported between said cover board and said loop flange of said solar cell assembly; a bottom cover covered on said base at the bottom; a power supply control circuit fastened inside said base and connected to said solar cell assembly via said light emitting elements, said power supply control circuit being comprised of an IC board, a storage battery and a power switch; wherein the radiant energy of sunlight collected by said solar cell assembly is converted into electric power for charging said storage battery, by means of the operation of said IC board, so as to further drive said light emitting elements to flash signals intermittently by means of the control of said IC board and said power switch.
