Abstract
Abstract A solar power-operated, construction work warning lamp which is consisted of a base secured inside a lamp guard and covered by a top cover and a bottom cover to hold a solar cell assembly and a light emitting assembly, wherein a light intensifier is fastened to the base on the top and secured in place by a framed seat and an enclosing wall, to intensify the intensity of light given by the solar cell assembly. The light intensifier is consisted of two symmetrical condenser lens assemblies connected into a cylindrical shape covered around the light emitting assembly to hold a plurality of condenser lens for intensifying the intensity of light given by the light emitting elements on the light emitting assembly.
