汽车有触点电子闪光器的振荡电路有分立元件电路、普通集成电路和专用集成电路3类。文中给出了各种电子线路的极限参数,并对各线路的优缺点进行了分析;提出国产继电器普遍存在耐久性差的问题。推荐了一种功能齐全、可靠性高的电子闪光器,它由进口专用集成电路、闪光器专用继电器组成,具有灯泡损坏、过压、过流或短路检测功能,解决了继电器耐久性差的问题。There are three types of oscillating circuit: discrete circuit, general integrated circuit and special integrated circuit for electronic contact flasher on vehicle. This article gives the limit parameters of each electronic circuit, analyses the merits and demerits and indicates that the durability of domestic relays is generally poor.A type of electronic flasher of full function and high reliability which consistes of imported special integrated circuits and flasher special refays are recommended. It features of functions of detecting the lamp damage, overtension, over current and short circuit, so that the poor durability problem is solved.
There are three types of oscillating circuits of electronic flash with contact points: discrete component circuit, common integrated circuit and special integrated circuit. In this paper, the limit parameters of various electronic circuits are given, and the advantages and disadvantages of each circuit are analyzed. It is proposed that the durability of domestic relays is generally poor. A fully functional and highly reliable electronic flasher is proposed. It consists of an integrated circuit for import and a special relay for flasher. It has the function of bulb damage, overvoltage, overcurrent or short circuit detection and solves the problem of poor durability of the relay.
