Description: A production of neon flash pattern controller:
The commonly used two types of high-pressure neon flash pattern controller due to cam wear, copper, wear or motor damage, but not working properly, but also because of its low-speed motor mechanical transmission can not be governor, limiting its flexibility. The neon light-emitting pattern control circuit shown has the advantage of long life, the logic function, low cost (only 40 of the mechanical control), and a simple structure.
This circuit can control 1, 2, 3, 4 words to the neon lights were lit, and that "the pattern expand 4,3 word turn off, ie," the pattern of recovery " in the first word of the brightest on the basis of a , 2,3,4 a word followed by independent light, and then scratch cycle.
2, the circuit schematic:
The IC5 time base integrated circuit composed of the pulse oscillator, the clock pulse for IC1 decimal count/distributor. IC1 10 outputs Q0 ~ Q9 is composed of a dual-quad output circuit used to control t
