Three-way flashing light string circuit (4)
As shown in the figure, it is a three-way flashing light string controller with novel jumping, it can make light string be lit one by one and extinguished together, then lit one by again, and it works in the cycle. The circulation rate of circuit is mainly determined by the charging time constant of R6, C2, which can be adjusted according to needs; VT1 ~~ VT3 can choose ordinary MCR100-8 small plastic unidirectional transistors; the power of each street light string is preferably at 100W or less.
