High-end step dimming light controller circuit (2)

It is a novel high-speed step- dimming light controller. It has the following functions: It can control the street lamp E]
with four-step step dimming of strong, medium, weak, strong light and extinguishing: it can make the electric lamp E] to ih, 2l ,, 4h and 8h grid timer
off function; in addition, it can also control the opening and closing of one wall lamp E2 to control the work of one H light. When
using and operating, all operations are implemented with a light touch button switch. Each time you press it, the corresponding LED will light up and the buzzer
will sound.
    The circuit bobbin device is a HA3102 electric fan control special integrated circuit, which has strong, medium and weak
wind speed control, 8h four-stage non-progressive electronic timing (1, 2, 4, 8h); there are A group of non- Independent swing head control
output. It comes in a standard DIP-18 package and uses a supply voltage in the range of 5-6V. In the picture, L. It is
the inductor coil in the ordinary electric fan speed reducer. Now three of the wires are used according to individual needs. L. It is
a ballast matched with the fluorescent tube.
    This circuit uses the second swing head output terminal s02, which is the output signal of pin ⑥, as the wall lamp E2 control signal, and the first
swing head output terminal S()], which is the output signal of pin @, as the fluorescent lamp control signal. When in use, just press
the dimming button SH3 to turn on the light FJ in port H. The internal noise program of BA3102 starts with wind conditions, that is, the thyristor VTHZ
is turned on first, due to the inductor f. ． String ^, lamp E emits medium light, and automatically switches to weak wind after 3 seconds, that is, VTH1 is turned on,
V. I F12 is turned off, j. ． All the strings are connected to the El power supply circuit. At this time, the brightness of the lamp El is the dimmest. If you need to change the brightness of lamp El
, press SB3 again to make the ⑩, ⑥, and ⑥ pins of the integrated block appear low in sequence, so
the thyristors VTHl-VTH3 can be turned on in turn to select the appropriate brightness. When changing the brightness of the light,
the corresponding light-emitting diode will light up for indication, and the buzzer Bl will also buzz. If you press the timer button
SB2, the light El can be turned off regularly. Press l, 2, 4, 8h... to cycle through. When the electric lamp E1 is in the scheduled working
state, the display of the luminous tubes I, ED1~I, and ED4 will show the remaining time as time passes, clearly showing
how long the electric lamp I1 can stay on. Press SR1 to control the on and off of the wall lamp E2, and SB5 to control the on and off of the R light
. Press one F SH4 to turn off all lamps. Bl is a +27mm piezoelectric ceramic piece, B2 is a 32768Hz quartz crystal, and the quartz vibrator
    in the electronic watch can be used .
SB1-SB5 is best to use 6X6 small touch button switches. The parameters of other components are shown in the figure, and
there are no special requirements.
