Abstract

PURPOSE: To light on and off lamps at random and heighten the display effect, by connecting a pulse generator circuit, a BCD counter and a BCD 7-segment decoder in sequence and controlling lamp switching circuits by the output of the decoder.
CONSTITUTION: Rectangular waves as shown in Fig. are produced by the output of the pulse generator circuit 1 made of a gate intergrated circuit. The BCD counter 2 receives said output to generate logic outputs A∼D. The BCD 7-segment decoder 3 produces logic outputs a∼g from the outputs A∼D. The plural switching circuits for the lamps La∼Lg are connected to a commercial power source 4 and the lamps and have switch elements which are bidirectional triode SCR's Ta∼Tg. The outputs a∼g of the decoder 3 are applied as control signals to the gates of the SCR's through resistors Ra'∼Rg. The lighting on and off of lamps La∼Lg is repeated according to the control signals.
