【摘要】：LED照明是现代照明发展的一个主要方向,LED照明有着绿色环保这个特点的照明系统。作为未来发展的方向,LED有着寿命长,节能省电,应用方便简单,设计容易,使用成本低廉等特点。目前正在取代白炽灯,以后会逐步取代荧光灯,节能灯,成为世界上第四代照明工具。随着目前的网络发展和人们对家居智能化的要求提升,照明也要能融入照明智能控制系统。用户可以通过数字可寻址照明接口dali来控制LED灯的开关以及亮暗。 LED驱动器是用反激式拓扑结构来设计,运用次级反馈来控制电流精度。现在要加入智能控制系统,LED驱动器也必须能接受网络智能控制软件,所以在驱动器中加入了DALI控制来调光,同时还能检测驱动器的工作状态并且及时反馈给智能控制系统。本文重点在于设计DALI调光电路进入LED驱动器,并且完成整个驱动器的设计和调试。
[Abstract]:Led lighting is a main direction of modern lighting development, LED lighting has the characteristics of green and environmental protection lighting system. As the direction of future development, LED has the characteristics of long life, energy saving, simple application, easy design and low cost. Incandescent lamps are being replaced and will gradually replace fluorescent lamps and energy-efficient lamps as the fourth generation lighting tools in the world. With the development of network and the requirement of home intelligence, lighting should be integrated into lighting intelligent control system. The user can control the switch and brightness of LED lamp by digital addressable lighting interface dali driver is designed with flyback topology and secondary feedback is used to control current accuracy. In order to join the intelligent control system, the LED driver must be able to accept the network intelligent control software, so Dali control is added to the driver to adjust the light, at the same time, it can detect the working condition of the driver and give feedback to the intelligent control system in time. The emphasis of this paper is to design the Dali dimming circuit into the LED driver and complete the design and debugging of the whole driver.
