    摘要: A concentration photovoltaic cell system with light guide includes a concentrator for focusing sunlight; a light guide located at where the sunlight is focused by the concentrator, so that the focused light is fully coupled to an input end of the light guide and propagates to an output end of the light guide; and a solar energy converter arranged at the output end of the light guide for receiving and converting the light projected from the light guide into electric energy. With the above arrangements, the solar converter may be located at a place not exposed to sunlight to avoid lowered energy conversion efficiency caused by temperature rising at photovoltaic cell chips thereof, and the use of the light guide enables increased GCR and light concentrating efficiency to enable reduced number of expensive photovoltaic cells.

    摘要: A protection circuit for power of a car is located between an output terminal of a car power and a car's electronic device input terminal. The protection circuit includes a transient voltage suppressing diode, a diode, and a filtering circuit. The two terminals of the transient voltage suppressing diode are connected with the output terminal of car power. The diode is connected with the transient voltage suppressing diode and the output terminal of car power. The filtering circuit is connected with the diode and the car's electronic device input terminal. Thereby, the transient voltage suppressing diode of the present invention clamps the ripple at a safe voltage to assure the life of the car's electronic device. Furthermore, the transient voltage suppressing diode and the filtering circuit can prevent the car's electronic device from being interfered and damaged due to the ESD. The reliability of the electronic device is enhanced.
