flasher, by definition, when a signal lamp for an automobile vehicle will be prompted to turn back and forth to remind owners and pedestrians, is an essential system in a car.
1. Principles steering light
First, the xenon lamp using lamp, microprocessor control circuit, about the rotation stroboscopic uninterrupted operation.
Second, the use flasher: their different structures, may be divided into resistive wire, capacitive and electronic three. Wherein the resistance wire can be divided into hot wire type of formula (electrothermal) and flap of formula (Bounce), and can be divided into electronic hybrid (with relay contact type electronic component) and the full electronic (non-relay ). Pop-up flash of example, using the principle of thermal effect of current to thermal expansion and contraction as a driving force, the spring piece mutate operation to turn on and off the contacts, to achieve lights flashing.
