一种基于SC8P1710C单片机的定时球泡灯设计

Design of a Timer Bulb Based on SC8P1710C MCU

针对照明行业常用的LED球泡灯作为定时灯提出了方案,在球泡灯内增设SC8P1710C单片机,并在灯体上设置定时开关,使用户可通过拨动开关设置定时时间。通过将电网交流频率信号转换成脉冲波输出至单片机用于计时,并根据定时时间控制LED光源供电电路工作状态,从而达到定时效果。测试结果表明,该方案可以实现对定时灯的精准控制,能够满足消费者对不同场合的需求。

This design puts forward a scheme for LED bulb lamp which is commonly used in the lighting industry as timing lamp.By adding a microcontroller unit(MCU)SC8 P1710 C in the bulb lamp and setting a timing switch on the lamp body,users can set the time of the lamp by turning the switch.The time detection circuit converts mains AC frequency signal to pulse signal to MCU.MCU would counts the time length according to received pulse signal and control the working states of LED light source power supply circuit base on the setting time,so as to achieve the timing effect.Test results show that this design is able to realize precise control of timing lamp,meeting the needs of consumers for different occasions.
