The figure1 is a LED luminescence circuit. This circuit is widely used in factory's automatic production line, as optical switch, it can measure whether has block objects pass though. In the circuit, NE555 produces pulse current with small duty ratio, it can make LED shine. When VT2 cuts off, it charges, when VT1 turns on, it dischanges, then LED can obtain larger current. Because it adopts pulse luminescence mode, so it can reduce power consumption.
