Abstract: Light device control circuit includes signal processor; control circuit including control signal source and active switch, active switch having output end thereof electrically connected to control input side of the signal processor through control bus; data synchronization circuit including data signal source and another set of active switches, and the output end of the another set of active switches being electrically connected to data input side of signal processor through data bus, signal processor forming electrical connection with signal connection circuit by data output side to form signal and command synchronization between data input side and data output side; and warning light control IC connected to warning lights and forming electrical connection with data bus outside data output side, and transmitting data, clock pulse and ID information from data output side, so that the starter and the receivers select one of the flash modes to flash the light.

Abstract: Method of controlling warning lights to enter low power mode includes steps of: setting predetermined ID Number of warning lights as starter, and remaining ID numbers as receivers; warning light set as starter receiving start command from control bus through signal line, and sending data, clock pulse, and ID information from data bus, and choosing low power mode to flash; warning lights set as receivers obtaining data, clock pulse, and ID information from data bus through signal lines, and flash mode of receivers and starter flashing in low power mode, and active switch of control circuit that executes low power mode receiving low power command sent from starter and forming conductive state, and current-reducing resistor which is electrically connected to active switch reducing passing current to predetermined ratio, so that reduced current is transmitted to receivers and then starter executes low power mode and reduces brightness of warning lights.

Abstract: A warning light control method includes the steps of: accepting multiple warning lights to receive a start command to set up Flash Mode and numbering each warning light sequentially starting from 1, and using Flash Mode number to synchronously set ID Number of each warning light; setting the ID Number of a predetermined warning light as Starter and the remaining ID Numbers as Receivers; the warning light of Starter receiving Start Command from Control Bus through cable, and sending Data, Clock Pulse and ID Information from Data Bus, and selecting one for flashing by Flash Mode; warning lights of Receivers get Data, Clock Pulse and ID Information from Data Bus through cables thereof, and warning lights of Receivers and Starter are flashing synchronously or asynchronously; whether Control Bus of Starter and Receivers has received Change ID Command.
