Fig. 1 is existing motor turning flash controller circuit theory diagrams.As shown in Figure 1, this flash controller mainly is made up of integrated circuit.Inner form by 2 comparators and 1 pulse generator and output circuit; Master oscillator frequenc mainly by R1, C1 decision, detects the current potential on the 7 terminal resistance R3, when a king light fracture of wire after-current reduces in comparator K1; The last current potential of R3 will reduce, thereby quickflashing is reported to the police.3 terminals work to drive relay J, with the open and close of control contact, promptly control the light on and off of Lamp for indicating change of drive direction.
But there is disadvantage in this flash controller:
1, pole changer is in the bulb load circuit, and therefore high to the requirement of switch contact, switch is fragile, and reliability is bad.
2, this circuit under normal circumstances has only when the photoflash lamp load and could work during greater than 10W.Common steering load power is 47W (voltage is 12V), and electric current is 3.92A, when the electric current＜2.7A of photoflash lamp, its power＜32.4W (voltage is 12V), begins quickflashing and reports to the police.Be that the electric current variation more just can detect.
Along with progress of science and technology, need automobile to reduce power consumption, increase the life-span of each device, to reach purpose energy-saving and cost-reducing and environmental protection.Along with the generally employing of auto electronic product, a kind ofly save the energy, pollute less, efficient is high, large-power light-emitting diodes (LED) that the life-span is long has been used in Lamp for indicating change of drive direction, stop lamp and the taillight of medium-to-high grade automobile.After king light had adopted the LED lamp, its power had only 1/4～1/5 of original power, i.e. 5～6W, and current sinking generally is not more than 480mA.
But; Original flash controller can't detect little current signal, can quickflashing when connecing the LED lamp reports to the police, and therefore in the going of automobile, can't realize the multiple effective control to turn signal; Be that reliability is not high, the result causes potential safety hazard in the running process.
