LASER CONTROL CIRCUIT, CONTROL METHOD AND LASER INK LINE DEVICE HAVING LASER CONTROL CIRCUIT |
摘要 |
A laser control circuit, comprising at least two laser tubes and a control unit controlling the at least two laser tubes respectively; the control unit sends control signals to the at least two laser tubes to control startup/shutdown thereof. The control unit comprises: a main pulse signal generator (1) and a logic control unit; the main pulse signal generator (1), the logic control unit and the at least two laser tubes are connected successively; and the logic control unit classifies the control signals into different types of control signals and sends to the at least two laser tubes, causing the at least two laser tubes to present different working conditions. The laser control circuit has more flexible control over the laser tubes, reduces working current of the laser tubes and allows the working current to be steadier, thus avoiding peak interference. |
