【摘要】：LED照明是現(xiàn)代照明發(fā)展的一個(gè)主要方向,LED照明有著綠色環(huán)保這個(gè)特點(diǎn)的照明系統(tǒng)。作為未來發(fā)展的方向,LED有著壽命長,節(jié)能省電,應(yīng)用方便簡單,設(shè)計(jì)容易,使用成本低廉等特點(diǎn)。目前正在取代白熾燈,以后會(huì)逐步取代熒光燈,節(jié)能燈,成為世界上第四代照明工具。隨著目前的網(wǎng)絡(luò)發(fā)展和人們對(duì)家居智能化的要求提升,照明也要能融入照明智能控制系統(tǒng)。用戶可以通過數(shù)字可尋址照明接口dali來控制LED燈的開關(guān)以及亮暗。 LED驅(qū)動(dòng)器是用反激式拓?fù)浣Y(jié)構(gòu)來設(shè)計(jì),運(yùn)用次級(jí)反饋來控制電流精度�，F(xiàn)在要加入智能控制系統(tǒng),LED驅(qū)動(dòng)器也必須能接受網(wǎng)絡(luò)智能控制軟件,所以在驅(qū)動(dòng)器中加入了DALI控制來調(diào)光,同時(shí)還能檢測(cè)驅(qū)動(dòng)器的工作狀態(tài)并且及時(shí)反饋給智能控制系統(tǒng)。本文重點(diǎn)在于設(shè)計(jì)DALI調(diào)光電路進(jìn)入LED驅(qū)動(dòng)器,并且完成整個(gè)驅(qū)動(dòng)器的設(shè)計(jì)和調(diào)試。
[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.
