Introduction to the Function and Principle of Electronic Flashers

Introduction to the function and principle of electronic flashers:

Function: Decoding LED turn signal flicker, rapid flashing, no flashing, and slight brightness phenomena. Characteristics of electronic flasher: This uses a dedicated integrated block, with a wide voltage range, stable frequency, and long lifespan. Generally applicable to Japanese vehicles such as Toyota, Lexus, and Lingzhi. Standard foot position, plug and play. It is very convenient to use or replace. The necessary flashing relay for converting the original car's turn signal bulb into an LED light has high starting sensitivity.

The function of electronic flashers: used for turn signals and hazard warnings.

The principle of electronic flasher:

When the current passes through the electrical limit R1, a voltage drop is generated on the electrical R1, and the transistor vT conducts due to forward bias. The collector current passing through the escape coil is small, causing the normally closed contact of the maintenance device to immediately open and the right turn signal light to turn off. At the same time as the transistor V conducts, the base current of V charges the capacitor C. Reduce when the current is insufficient during the TEPCO process. With the development of capacitor capacitors. The charging speed is gradually decreasing, and the collector root fatigue ratio of the transistor is also becoming brighter. When releasing to maintain the attraction of the armature, the contacts of the relay are used again, and when the turn signal is high again, the poison C is triggered by the normally closed electric battery and pusher, causing the small electric valve RB to malfunction. The discharge current on R2 generates a forward bias voltage for the transistor to conduct.
