摘 要: 设计了一套应用于宿舍、工作室及大型停车场的LED智能照明系统。利用9 V变压器与LM7805组成交流转直流5 V稳压源为系统供电,通过热释电红外探测器采集数据,无线模块实现全区域内的数据传输,采用大功率LED恒流驱动方案,并利用可调光芯片BP1360和先进的PWN技术对LED灯进行调光,同时利用脉宽调制技术控制舵机,使得LED灯在两个自由度(各180°)上自由旋转,自动锁定空间的5个位置实现照明,同时可以通过手动遥控器进一步对系统进行控制,自由选择照明方式,体现对LED灯的智能化和人性化,进一步实现绿色节能照明。 This work designed a set of LED intelligent lighting system which can be applied in the dormitory, studio and large parking. Use LM7805 and 9 V transformer turn ac voltage to dc 5 V for system current supplication, We use pyroelectric infrared detector in data collection, wireless module implements in all areas of the data transmission, using high power LED constantcurrent drive scheme, and by using adjustable light chip BP1360 and advanced the PWM move light of LED lights implement, at the same time use pulse width modulation technology, make leds for steering gear control in two degrees of freedom (180 °) on each rotate freely, auto target space of five, and can realize lighting position by manual remote control the system is controlled, further free choice lighting system, this system embodies the intelligent of LED lights and humanization, further realize green energy-conserving lighting.
