Alternating current and direct current mixed use of ballast by relay

Abstract

The invention discloses the alternating current and direct current mixed use of a ballast by a relay. A structure consists of the relay, a diode, a direct current power cord, an alternating current power inlet wire, a signal wire, a transformer, a control module and an alternating current power outlet wire, and is characterized in that the direct current power cord is connected with a primary positive pole of the transformer; the normally closed end of the relay is connected with the alternating current power outlet wire, and the common end of the relay is connected with the alternating current power inlet wire; the anode of the diode is connected with the signal wire, and the cathode of the diode is connected in parallel with the power input end of the control module and one end of a coil of the relay; and the other end of the coil of the relay is connected with a negative pole. In the off state of an illumination lamp, matching between a magneto and a rectifier is unchanged, and after an engine is started, and the illumination lamp is turned on, the loss of an illumination wire in the rectifier is cut off, so that the charging efficiency of the rectifier is improved, and a function of alternating current and direct current power mixed use of an alternating current illumination system is realized.

Description

technical field [0001] The invention relates to a power input control device of an HID ballast for motor vehicle lighting, in particular to an AC / DC mixed use of the ballast by means of a relay. Background technique [0002] The headlights of motorcycles with AC lighting must work after the vehicle is started. The brightness of the lighting bulbs is affected by the speed of the engine, which poses a safety hazard to the driver. It is necessary to change the AC lighting to DC lighting. To match the coils of the rectifier and magneto brings cumbersome maintenance work and increases costs. Contents of the invention [0003] The purpose of the present invention is to provide a relay to realize the mixed use of AC and DC of the ballast, so that the function of DC lighting can be realized without changing the power generation system of the original vehicle. [0004] The present invention is realized by the following technical scheme: the AC and DC mixed use of the ballast is r...
