摘要： A fluorescent lamp starter circuit includes a relay which forms a first circuit loop to detect the input voltage and to switch the relay from the normally-closed position to the normally-open position once the input voltage reaches the threshold level. The switching of the relay to the normally-open position opens the first circuit loop and closes a second circuit loop constituted partly by the relay to allow current to flow through and heat up the electrodes of the fluorescent lamp. After a certain time period, the relay, which is controlled by the discharging of a capacitor, is switched back to the normally-closed position to open the second circuit loop. The electrodes of the fluorescent lamp, after having been heated, begins to emit electrons and this lowers down the impedance that it represents so that the voltage across the first circuit loop is not sufficient to actuate the relay so as to maintain the relay at the normally-closed position.

摘要： The present invention provides a network device and a control method thereof. The network device comprises: a receiver, a first timer, a transmitter, a detector, and a controller. The first timer is utilized for calculating a first predetermined time. The transmitter is coupled to the first timer, and utilized for generating a network linking signal and outputting the network linking signal. The detector is coupled to the receiver, and utilized for detecting a link status of the network device and a link partner to generate a first detecting result. The controller is coupled to the first timer, the transmitter, and the detector, and utilized for determining whether to power down the transmitter according to the first detecting result and the first predetermined time.
