《汽车电器》1981年第2期“三谈晶体管闪光器”文介绍了当时探索中的一种“有触点晶体管闪光器”为使它更按近实用,近几年我们又对电路进行了不少改进。改进后的晶体管闪光器电路原理图,见图1它有两点明显进步:一是线路简单,使用元件少,由原来13只减少到6只而且性能稳定,闪频70~90次/分,通电率0.4至0.6;二是完善了性能,当信号灯出现断丝故障时。闪频能发生明显改变．有良好的监视作用例如,当正常工作频率为75次/分时,断一只21CP信号灯后,频率上升到114次/分。
“Automotive” 1981 the second issue of the “three talk about transistor flasher” article introduced at the time of exploration of a “contact transistor flasher” to make it more practical, in recent years, we have the circuit A lot of improvement. Improved transistor flasher circuit diagram, shown in Figure 1 it has two significant improvements: First, the circuit is simple, using fewer components, reduced from the original 13 to 6 and stable performance, flash 70 ~ 90 times / min, Power 0.4 to 0.6; Second, improve the performance, when the signal appears broken wire fault. Flash frequency can change significantly. For example, when the normal operating frequency of 75 beats / min, cut off a 21CP signal, the frequency rose to 114 beats / min.
