Abstract: The present disclosure provides a driving system for a semiconductor light source and a semiconductor lighting device. The driving system comprises: a transformer, the transformer comprising a first coil (201) and a second coil (202) mutually coupled to each other, the second coil (202) being used for receiving an input voltage; a switching device which is connected in series to the second coil (202) and used for controlling energy storage and energy release of the second coil (202); and an outputting device which is connected in parallel to the second coil (202) and used for supplying power to the semiconductor light source. An induced signal is generated on the first coil of the transformer due to a coupling effect between the first coil and the second coil and is used for controlling the switching-on and switching-off of the switching device.

Abstract: A commode-urinal is provided with a cleaning-water path connected with water-supplying facilities; the commode-urinal is provided with a draining-off path connected with a sewer-path. The commode-urinal is used together with commode-excrement container as a set thereby the commode can process urine and excrement by different methods. When it is used to process urine, it can effectively solve the existing problems of using water unreasonably and wasting water due to unscientifical processing methods.

Abstract: Men's briefs and lining of the briefs comprising a waistband section, a front section, and a back section, wherein a support belt is connected to the front section. The bottom of the support belt has an arc shape and forms a bag section between the bottom of the tightening position of the scrotum and the upper ends of the wearer's legs. The bag section formed at the bottom of the front section facilitates the supporting and holding of the scrotum. The two ends of the support belt flare up and are connected with the front section and the waistband section to facilitate the stability of the support belt and the supporting force. The support belt itself can be adjusted easily by adjusting the width of the flared mouth of the support belt, the length of the support belt, or the tension of the elastic ribbon. Thus, with adjustment by the wearer, the proper support position and a comfortable supporting force can be attained.
