The 220v ac voltage will provide IC with 6v direct current working voltage after it is reduced by C3, rectificated by VD1,VD2, stablized by VS, filtrated by C2. IC's Q1-Q7 terminals serve as drive signals output terminals. B1-B3 terminals serve as various choices control terminals. Uc and UD serve as consumption control terminals. OSC1 and OSC2 serve as oscillate terminal. After IC begins to work, its Q1-Q7 terminals will output drive signals which will control the7 circuits of illuminations HL1-HL7 by VT1-VT7. When IC's B1-B3 terminals are not connected, illuminations HL1-HL7's illumination effects are multipoint illumination, as seen in figure 1-3.When the illuminations are used, the illumination effects can be set according to actual requirement.
