1、led 矿灯驱动电路设计The Design of LED Miner”s Driving Circuit Author:Yang LeiTutor:Li Haixia AbstractWith the development of semiconductor lighting, LED is already a research hotspot,and is showing tremendous potential and brightprospect.Since LED miner”s lamp is its, compares with fluorescent lamp with whi
2、te heat tengsten lamp. Major technical advantage is little for volume , give out heat to measure is low ( no heat radiation ) , power consumption is little ( low voltage and low current start ) , the life long response speed ( above theoretical life one-hundred thousands hs) is quick ( incorporate s
3、econd few levels ) , endure vibration and impact and free from contamination. As miner”s lamp light source,LED is consistentwiththetechnicalspecificationsandsafety requirements.Nowhugemanpowerandfinancialresourcesare investedtoresearchLED,andthefocusareenhancingthe performance and reducing the cost.
4、The electrical and optical characteristics are introduced at first.Then, a LED miner”s lamp and a high power constant current system for driving LEDs are designed, using the technology of electronics and switching power supply. The latest HB-LED, the specialized chip for LED driving . It can be seen
5、 that the miner”s lamp based on LED is better in lighting, working for longer time, of longer lifetime, smaller in size, and maintenance free, which holds great advantage compared to traditional miner”s lamp. It is a revolutionary product in the coal mine industry.At last, the proposals to improve t
6、he miner”s lamp and the LED driving system are given, and the development of LED and its driving technology is expected.Key Words:LED ,* ,Drive circuit,Miner目 录1 绪论11.1课题研究背景及其意义11.2 课题研究现状11.3 课题研究方法21.4论文的组成及重要内容框图22 LED在 矿 灯 照 明 的 发 展 和 行 业 标准42.1LED光源带动照明产业革命42.2 煤 炭 行 业 的 矿 灯 标 准 和 设 计 注 意 事项42
