【摘要】：LED光源照明如今在全球發(fā)展迅猛。由于LED光源照明系統(tǒng)壽命長(zhǎng)、可靠性高、節(jié)能和易于智能控制等優(yōu)點(diǎn),已經(jīng)取代了大量的傳統(tǒng)照明。作為L(zhǎng)ED光源照明系統(tǒng)中核心部件之一的LED光源電子驅(qū)動(dòng)器,其性能與電氣參數(shù)的設(shè)計(jì)也顯得非常重要。它的設(shè)計(jì)好壞也將直接影響到整個(gè)LED光源照明系統(tǒng)是否能夠體現(xiàn)其優(yōu)勢(shì)的關(guān)鍵。現(xiàn)今整個(gè)LED光源照明市場(chǎng)的競(jìng)爭(zhēng)異常激烈,大部分LED光源電子驅(qū)動(dòng)器的功率受產(chǎn)品自身成本和可靠性的壓力,輸出功率普遍不是太高,大部分都在100W以下。這在一些需要高亮度照明的應(yīng)用場(chǎng)合就會(huì)受到很多的條件制約,不利于產(chǎn)品參與市場(chǎng)競(jìng)爭(zhēng)。另一方面,由于全球各國(guó)基礎(chǔ)設(shè)施的差異及其法律法規(guī),標(biāo)準(zhǔn)體系的差異所形成技術(shù)壁壘,往往使很多LED光源電子驅(qū)動(dòng)器的制造商只能針對(duì)某一國(guó)家的特定市場(chǎng)來(lái)進(jìn)行產(chǎn)品的研發(fā)設(shè)計(jì)去符合該市場(chǎng)的需求。這種單一性,針對(duì)性較強(qiáng)的產(chǎn)品,局限性也很明顯,市場(chǎng)競(jìng)爭(zhēng)力較弱,往往不利于去開(kāi)拓其它國(guó)家的市場(chǎng)。本文提出了設(shè)計(jì)一款能滿足全球市場(chǎng)準(zhǔn)入的高功率(150W)LED光源電子驅(qū)動(dòng)器產(chǎn)品的可行性。從全球主要的兩大標(biāo)準(zhǔn)體系(一是以美國(guó)為主的北美國(guó)家,另一個(gè)是以國(guó)際電工技術(shù)委員會(huì)會(huì)IEC為主的全球大部分國(guó)家)對(duì)兩者所頒發(fā)的針對(duì)LED光源電子驅(qū)動(dòng)器產(chǎn)品的法律法規(guī)和安全規(guī)范出發(fā),如電磁兼容、輸入電流諧波和產(chǎn)品安全設(shè)計(jì)之間的差異和具體要求進(jìn)行闡述和分析,最后決定采用了濾波線路,有源功率因數(shù)校正線路和LLC諧振軟開(kāi)關(guān)線路的設(shè)計(jì)方案。然后進(jìn)一步對(duì)相關(guān)電子線路的工作原理和產(chǎn)品安全設(shè)計(jì)的要求進(jìn)行了詳盡的分析和電氣參數(shù)進(jìn)行設(shè)計(jì)。最終設(shè)計(jì)出的150W高功率LED光源電子驅(qū)動(dòng)器通過(guò)了該類產(chǎn)品所規(guī)定的相關(guān)測(cè)試,以成功的測(cè)試結(jié)果來(lái)驗(yàn)證該產(chǎn)品的最終設(shè)計(jì)是符合到預(yù)期的設(shè)計(jì)要求,是一款可以參與全球市場(chǎng)競(jìng)爭(zhēng)的高功率LED光源電子驅(qū)動(dòng)器。
[Abstract]:LED lighting is developing rapidly all over the world.Because of the advantages of long life, high reliability, energy saving and easy intelligent control, LED lighting system has replaced a large number of traditional lighting.As one of the core components of the LED lighting system, the design of the performance and electrical parameters of the LED light source electronic driver is also very important.Its design will also directly affect the whole LED lighting system can reflect its advantages or not the key.Nowadays, the competition of the whole LED lighting market is very fierce. Most of the power of LED light source electronic driver is under the pressure of product cost and reliability, the output power is generally not too high, most of them are below 100W.This will be restricted by a lot of conditions in some applications that need high brightness lighting, which is not conducive to the participation of products in market competition.On the other hand, due to the differences in infrastructure, laws and regulations, and the differences in standards systems,Often, many manufacturers of LED light source electronic drives can only develop and design their products in a specific market in a given country to meet the needs of that market.This kind of single, pertinence product, the limitation is also very obvious, the market competition ability is weaker, often is unfavorable to open up the market of other countries.This paper presents the feasibility of designing a high power 150WN LED light source electronic driver which can satisfy the global market access.From the two major standards systems in the world (the first is the North American country, which is dominated by the United States),The other is that most of the world's countries, dominated by the International Electrotechnical Commission (IEC), issue laws, regulations and safety regulations for LED light source electronic driver products, such as electromagnetic compatibility.The difference between the input current harmonics and the safety design of the product is expounded and analyzed. Finally, the design scheme of filter circuit, active power factor correction line and LLC resonant soft switch circuit is decided.Then the working principle of related electronic circuits and the requirements of product safety design are analyzed in detail and electrical parameters are designed.Finally, the 150W high power LED light source electronic driver has passed the relevant tests stipulated by this kind of product, and the final design of the product is verified to meet the expected design requirements with the successful test results.Is a high-power LED light source electronic driver that can participate in the global market competition.
