Four-way flashing light string circuit (9)

A high-power eight-pattern four-way flashing light controller made with M800561-3 light control integrated circuit .
M8005 6B is a product of Shenzhen Tianlang Semiconductor Education Co., Ltd. (http://j:'www.tiro.cc), Department of ( , MOS
Dingqi manufacturing. The chip adopts DIP-14 standard package, and the 35V voltage stabilizing unit has been integrated inside the chip, so
it can operate normally without an external voltage regulator.
    In the middle, the M80056B working power supply is stepped down by the transformer T Rectification supply, the four output terminals 11
to 1, 4 of the integrated block (that is, the ⑧ to ⑧ feet) drive 4 high-power bidirectional thyristors
VTHl-VTH4 through VTl-VT4 diodes respectively (it is suitable to use 12A, 7600V type, and install Aluminum radiator with sufficient area) to drive the four-way
colored lights FI, - F^ to shine. IIIH light-emitting diodes [.EDl - I.EJ) 4 connected in series in the VTl-VT4 collector circuit
should be installed on the controller On the panel, the colored lights are illuminated cyclically (their flashing is synchronized with the colored lights
). The ar control power of each channel of lanterns in this circuit can reach 1500W, which is suitable for facade decoration of shopping malls, large hotels, and
contour control of tall buildings. El-E4 can be used for incandescent lamps, gypsophila light strings or neon tubes, etc.
    The resistor provides AC synchronization signals for the integrated block. SB is the color light string pattern selection switch. Each time
SB is pressed, the color light string Just change the cycle pattern once. There are 8 change modes in FenglU Road, specifically: the first
mode is the second to seventh cycle; the second mode is the wave forward and backward, with one steep and slow; the third mode is the wave forward and backward. The first mode
is 4 kinds of horse racing flashing: the 4th mode is 3 single lights gradually brightening and gradually clearing; the 5th mode is the horse racing forward
and backward and the foot stars flashing; the 6th mode is 3 kinds of ~ g /J fading in and out at the same time. It is called fade-out; the 7th mode is for twinkling stars
and racing; the 8th mode is designed for string lights, and the mode can be used to check the quality of light string bulbs.
