Abstract: The present invention relates to a generator apparatus for a vehicle, which uses the pressure exerted on the wheels of a vehicle while the vehicle travels to generate electricity to provide a source of driving power for a vehicle that is driven by electricity, such as an electric car or a hybrid vehicle. The generator apparatus is installed on a rotating wheel of a vehicle and comprises a generator module including a plurality of piezoelectric devices that generate electricity by means of pressure transferred from the ground through the wheel when the wheel rotates, a condenser for storing electricity generated by the generator module, and a connecting unit electrically connecting the generator module to the condenser. The generator module may include a supporting member installed on the wheel flange and covered by a tire, and the piezoelectric devices installed on the supporting member.

Abstract: A solar power plant is provided. The solar power plant includes a plurality of first support members positioned in the front end of the solar power plant, main frames hinged to the respective first support members, a plurality of second support members positioned in the rear ends of the main frames, a plurality of sub frames rotatably installed on the main frames and arranged in parallel with one another, photovoltaic modules installed on the respective sub frames, and rotating means simultaneously rotating the sub frames with respect to the main frames by a predetermined angle in forward and reverse directions.

Abstract: A light emitting diode (LED) module having a cooling apparatus is provided, including a substrate having a plurality of LEDs installed thereon and installed on a bottom surface of the substrate, a container containing a heat exchange medium, and a peltier device installed on at least one side of the container to cool the heat exchange medium contained inside the container. The LED module can improve a dissipation characteristic of heat generated from a high-brightness LED while preventing the LED from degrading due to heat.
