Delayed light out circuit of motorcycle brake light

Delayed light out circuit of motorcycle brake light

The circuit principle as shown: S1 is power switch, controlled by frame lock, S2 is brake light control switch. closing switch S1, because the voltage in both ends of capacitor can be sudden changed, IC's ② pin is low level, brake light H on, a few seconds later, C1 is discharged, then the IC's ② pin voltage is higher than 1.6V, light H off. When the driving motorcycle is slow down or stop in an emergency, switch S2 is closed and shortened circuit both ends of C1 then discharge, turn switch IC's ② pin into low level, brake light H is lighted immediately, S2 resets, H is extinguished after a few seconds later. IC in the circuit is high power switch integrated circuit TWH8752, the maximum current is 4A, H is rear brake light, R1 is 470K, C1 uses 16V, 47μF electrolytic capacitor, C2 uses 25V, 2200μF electrolytic capacitor, VD1 uses 1N5408 rectifier diode. If it needs to change the delay time, just to change the values of R1, C1 appropriately. (View)
