Abstract

The invention provides an automatic ignition device for a lighted-off xenon lamp. One group of signal module is additionally arranged in a previous circuit. The automatic ignition device is characterized in that a voltage collection end of a signal module is in parallel connection with an anode of a discharge tube, a cathode of an energy storage capacitor, and one end of a circuit resistor; a power supply input end of the signal module is connected with an anode of a No.1 capacitor and one power supply anode wire is led out; a power supply cathode wire and a high-voltage cathode wire are led out from a cathode of the No.1 capacitor; a power supply output end of the signal module is connected with a triggering end of a control module; a high-voltage packet is connected with the energy storage capacitor; and meanwhile, a high-voltage anode wire is led out from a secondary grade of the high-voltage packet. After the xenon lamp is abnormally lighted off, voltage of the voltage collection end of the signal module is zeroed; electric energy is transmitted to the triggering end of the control module through the signal module; and the control module can restart a MOS(Metal Oxide Semiconductor) tube to enable a ballast to work.

Description

technical field [0001] The invention relates to an automatic ignition control device for a motor vehicle lighting ballast, in particular to an automatic ignition device for a xenon lamp when it is turned off. Background technique [0002] The operating environment of the vehicle is relatively harsh, and as a xenon lamp is one of the safety components to ensure night riding, the abnormal extinguishing of the bulb will bring serious safety hazards to the driver. Contents of the invention [0003] The object of the present invention is to provide an automatic ignition device for a xenon lamp when the lamp is turned off, so as to ensure the rapid self-starting function of the xenon lamp when it is suddenly extinguished. [0004] The present invention is realized by the following technical scheme: the automatic ignition device for turning off the xenon lamp is constructed by adding a group of signal modules to the original circuit. It is characterized in that the voltage acqu...
