Abstract: A solar power-operated cooling system installed in a motor vehicle for circulation of air, including a solar power device having a plurality of photovoltaic cells mounted for converting the radiant energy of sunlight into electric power and a power output terminal for output of electric power from the photovoltaic cells, an electric connector having an input terminal connected to the power output terminal of the solar power device and at least two output terminals, at least one blowing fan and at least one exhaust fan respectively installed in the interior door panel assemblies of the motor vehicle and electrically connected to the output terminals of the electric connector and driven to draw fresh air into or to draw hot air out of the motor vehicle.

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.

Abstract: A solar power-operated, construction work warning lamp comprising a base covered by a bottom cover to hold a power supply control circuit and a column, the power supply control circuit consisted of a storage battery, a power switch and an IC board, the column having a plurality of LEDs thereon respectively connected to the power supply control circuit, a lamp guard mounted on the base at the top and covered with a transparent, convex cover, a solar cell assembly supported on the column inside the lamp guard and electrically connected to the power supply control circuit, and a plurality of reflectors mounted on a plurality of openings around the lamp guard, wherein the radiant energy of sunlight collected by the solar cell assembly is converted into electric power for charging the storage battery and for driving the light emitting elements to flash signals by means of the control of the IC board and the power switch.
