【正文】 發(fā)展高效率、高功率因數(shù)、價(jià)優(yōu)的緊湊型模塊化 LED 電源 ， LED 供電簡(jiǎn)便，既可直流供電，又可脈沖供電。沒有 HID 和高壓霓虹燈的一系列麻煩。目前，低效率的供電系統(tǒng)，拖了 LED 的后腿，節(jié)能水平大打折扣。開關(guān)電源從 70 年代的 20KHZ 的標(biāo)準(zhǔn)到目前已達(dá)到 1MHZ 以上的軟開關(guān)技術(shù)，問題關(guān)鍵在于如何做到質(zhì)優(yōu)價(jià)廉。 3） 發(fā)展新型 LED 混光、混色技 術(shù) LED 光源，單位體積很小，在很多場(chǎng)合明顯是優(yōu)點(diǎn)，但有時(shí)又是缺點(diǎn)。如：在 LED 平面型光源上，通常出現(xiàn)點(diǎn)狀光斑以及混色不均勻現(xiàn)象。目前，混光、混色存 在的問題是：混光、混色的均勻水平與透光率的矛盾。這個(gè)問題也是阻礙 LED 發(fā)展的因素，主要是材料的原因，急待攻克，對(duì) LED 景觀燈具實(shí)用性有很重要的意義。 LED 進(jìn)入照明領(lǐng)域，是照明技術(shù)的革命性飛躍。 LED 對(duì)綠色照明發(fā)展的歷史性貢獻(xiàn)，將絲豪不遜于從電子管時(shí)代到晶體管時(shí)代的飛躍，即使評(píng)價(jià)為如同晶體管跨越到大規(guī)模集成電路的巨變一樣，也毫不夸張。 在景觀照明方面， LED 有著更為獨(dú)特的優(yōu)勢(shì)，可以深信， LED 景觀燈具將沿著多學(xué)科交叉融合的大道，朝著藝術(shù)化、智能化、柔性化的方向快速發(fā)展。 作者：王濱 . 《 LED光 源在景觀設(shè)計(jì)中的應(yīng)用》 . 照明設(shè)計(jì)， 2020年 5月 20日 大連交通大學(xué) 2020 屆本科生畢業(yè)設(shè)計(jì)（論文）外文翻譯 LED lighting in the landscape of Apart from the mercuryfree LED light source, saving energy, materials, environmental nonelectromagic interference, nonharmful rays five advantage, fields in lighting, especially in landscape lighting, there are many advantages. Such as: lowvoltage power supply no highpressure areas, in order to insulation costs much less, high reliability annex simple no starter, ballast or EHV transformer。 simple structure a solid source of the greatest advantages , Noncarbonated, nonglass case, no gas sealing problems, impact resistance。 controllable good fast response time (microsecond order of magnitude) can be repeated frequentlyout, basically inert, will not be tired。 color Chunhou Semiconductor PN junction produce their own color, pure, strong, rich colors plus three primary colors of digital technology, evolution of arbitrary color。 light structure wood, costsaving。 lamps on strength and stiffness requirements of very low The pact size of the LED lamps can be seen as the LED cells, only the smallest LED mm2 order of magnitude or less。 flexible good LED light source of the pact, LED can adapt to all kinds of different size and geometry of space size The decorative lighting requirements, such as: point, line, surface, the ball, different forms, and any form of art lighting sculpture。 visible, LED is worthy of a green lighting of the 21st century proud. LED decorative landscape lighting research and development due to the characteristics of the LED with a series of advantages, LED lamps in the landscape of research and development mainly in the following directions: garden lights, path lights, lamps and buried, small spotlights, Caoping Deng, the FastTrack Road Lamps, wall lamp, and so on. Source use LED, bined with changes in control, upgrading the Hongtuo on the landscape, making them more artistic tastes. Nonstandard profiled the development of landscape lighting, landscape lighting, lamps installed to
