The turn signal is an important indicator light that is turned on when the motor vehicle turns to remind the attention of the front, rear, left and right vehicles and pedestrians. The turn signal lamp adopts a xenon lamp and a single chip microcomputer control circuit. The blinker is used in the turn signal to make the light flicker. It can be divided into three types: resistance wire type, capacitive type and electronic type.
According to the materials used, it is divided into: 1. Gas car turn signal; 2. LED car turn signal.
Divided by base, divided into: 1. P21W; 2. PY21W; 3. W21W; 4, P27W; 5, W5W; 6. H5W.
Divided by location: 1. Front turn signal; 2. Rear turn signal; 3.Side turn signal
The resistance wire type can be divided into hot wire type (electric heating type) and fin type (bouncing type), while the electronic type can be divided into hybrid type (relay and electronic components with contact type) and all electronic type (no relay) ). For example, the bounce flasher uses the principle of current thermal effect and uses thermal expansion and contraction as the driving force to cause a sudden change in the spring leaf to switch on and off the contacts and realize the flashing of the light.
The turn signal is the most important device to display the dynamic information of the car. It is installed at the front and back of the car body, and is turned on when the car turns. To make the right judgment.
