使用LED驅(qū)動評估板的優(yōu)化改造照明設(shè)計(jì)

　　照明設(shè)計(jì)師最好能明智地使用現(xiàn)成的評估板或模塊，它們既是照明項(xiàng)目的基礎(chǔ)，又有助于加速設(shè)計(jì)周期。在某些情況下，利用數(shù)據(jù)本身可能不足以幫助你前進(jìn)，尤其是設(shè)計(jì)挑戰(zhàn)，例如，如果他們?nèi)狈λ袛?shù)據(jù)需要的供電照明系統(tǒng)如LED改造燈泡和照明應(yīng)用選擇最佳的LED驅(qū)動方案。

　　一些照明設(shè)計(jì)師面臨的試驗(yàn)包括實(shí)現(xiàn)調(diào)光能力，實(shí)現(xiàn)高效率，選擇正確的設(shè)計(jì)權(quán)衡，同時(shí)試圖擠壓到一個(gè)小空間的所有的電子產(chǎn)品。這些參考設(shè)計(jì)套件或評估板的重點(diǎn)是使它更容易解決這些任務(wù)，所以工程師可以快速實(shí)現(xiàn)LED驅(qū)動器集成電路到他們的設(shè)計(jì)。

　　我們將看看一些評估板的LED改造燈泡的項(xiàng)目，包括A19、PAR30 / 38、PAR20、GU10、和燭臺樣式的燈泡。一系列的參考設(shè)計(jì)套件和評估板可從公司如集成，向Digi-Key網(wǎng)站Power Integrations德克薩斯文書。

　　“LED lighting designs are really a balancing act，” said Andrew Smith， product marketing manager at Power Integrations. “There are multiple different features and requirements in different geographical regions. If this is your first time trying to manage all of these competing variables， it is extremely daunting.”

　　The role of a design evaluation board or reference design kit is to provide a design that is 75 percent completed， added Smith. “It makes it a lot easier to establish what you really need. You might have to modify a reference design， but you won‘t have to design it from scratch.”

　　Smith noted that Power Integrations’ reference design boards or kits offer a working， production-ready board. The idea is to give a designer something that looks like a real solution， which can be modified. The company‘s reference design kits include the board， schematics， Gerber files， complete bill of materials， blank boards to build a modified version of the circuit， and extra ICs to evaluate other devices in the same series， which typically provide a little more or less power. The included engineering test report also explains why specific trade-offs were made in the design.
