Source use LED, combined with changes in control, upgrading the Hongtuo on the landscape, making them more artistic tastes. Non-standard profiled the development of landscape lighting, landscape lighting, lamps installed to protect the landscape and environment, the prevention of lighting the visual impact, in order to beautify the day, under the artistic Lianghua night. This requires installation of lamps because of the structure and system to King, the architectural features to the system, many can not meet the standard lamps is more than required. LED lamps designed flexible, especially for the system to King because of the non-standard lighting design, landscape lighting and visual coordination, beautify the environment to achieve a new level.Art of Landscape Lighting lamps is itself a development of Visual Arts, and the LED light source can be more creative art of landscape lighting to a higher realm. As the controllable LED good, rich colors, and microelectronic technology intelligent control, to all kinds of ideas can be colourful and exciting joyful rhythm, melody beautiful landscape lighting. Such as: LED lights Perak, Perak than the gas-discharge lamps to be much more longevity, not damaged, and richcolors. Another example: LED lights winds, just intelligent computer control, we can achieve "No wind at the" rapid rotation, and also enables automatic transmission and for the wonderful color changes. Similar ideas, as long as the inspiration, can achieve.Lighting sculpture category of development, any of the simulation, bionics, comics, cartoons, commercial, tourism and so on the various lighting sculpture, and sound can be combined LED technology and microelectronics control, when necessary, together with On the mechanical and electrical integration technology, developed to attract people's attention a series of landsca lighting sculptures.LED lighting landscape of intelligent control technology, LED lighting landscape of intelligent control technology, a digital or analog technology, or computer control technology, for the most compact or embedded systems. Characteristics: high reliability, excellent prices; many changes in patterns; existing single-light control, another group control mode; many non-standard design; long long lamps or more (such as: long-zone, many Wall linear layout) ; LED display technology and a lot of difference. According to the landscaping requirements, changes in control mode, gives to rich and colorful, beautiful melody, rhythm joyful feelings, sometimes to shake the core to give people a strong boost. According to LED controllable, and the characteristics of rich color, color constitute almost unlimited. In accordance with the principles of the three primary colors and gray-scale digital control technology, on the principle of evolution to be almost beyond the arbitrary nature color. For example: three color LED, such as using only two gray-scale control, namely: the dark and can achieve eight kinds of color evolution; Another example: three color LED, a three-gray control, namely: that in the dark, To achieve 27 kinds of color changes; Another example: three color LED, such as the use of the eight digital control of gray, color categories has reached an alarming level, reaching 16.77 million kinds, even the names of every color you are too late Named.Currently, LED lamps electronic control structure, there are five or more categories: single-light control, light control group, or super-long span of control of lights, noise control, sensor control.On the performance of life, the silicone can be achieved to extend the service life of white LED target, or even reach more than 40,000 hours of life, but is not really suited to do the lighting on the application of research still needs to be, because the silicone Is a flexible soft material, so in the packaging process, the need to pay special attention to application of the way, from designing the most appropriate application of technology.For the future of the area, improve white LED light output efficiency will be key to winning the point. White LED production techniques, from a blue LED and a yellow YAGphosphor mix, developed a simulation of the white target, the use of colour or mixed use of GaN materials, developed a white LED, the applications have already Will be read out in the direction towards a more extensive expansion.In addition, the luminous efficiency white LED, which has been good in the development of LED lighting promoting the Japan Association goal is to look forward to in 2009 is expected to reach 100 lm / w the luminous efficiency, and in fact, a considerable number of In the industry towards the development of this area, is expected in the next few years, 100 lm / w luminous efficiency can actually commercial applications.LED micro-electronic control circuit design optimization of the focus is: reliable, the price of distinctions, using common components, sources of wealth. The length or long span of control lights in addition to the above requirements, but also has the following advantages, such as: Shu Shimi, 100 meters and 1,000 meters above the band or linear layout of the point source. Optimal Design of the objectives are: motion control, it is necessary to colourful, bringing amazing visual images, both of transition, have graded, but also to minimize - wire.LED development of the main issues to be tackled into the LED lighting is new to the area, is of epoch-making significance. However, as with any new technology, LED there are still some areas in urgent need of improvement.1) research and development of high power LED light source at the international level, Phlips, GE, OSRAN and other big companies have double-spherical HID products, which is currently the world's most advanced high-power HID light sources, especially Phlips company based on this source of sports Venues lamps, lamp efficiency and with very good light curve. Although LED many unique advantages, but this area is blank. High-power density point for the semiconductor LED light source on the principle of LED may be a lot of technical difficulties.2) the development of high efficiency, high power factor, the price of gifted compact modular power LED, LED power supply is simple, can DC power supply, power supply can pulse. HID no neon lights and a series of high-pressure troubles. At present, the low efficiency of the power supply system, dragged down by the LED, greatly reduced the level of energy. Switching power supply from the 1970s to 20 KHZ the standard has now reached more than 1 MHZ the soft-switch technology, the crux of the problem is how to achieve quality and cheap.3) the development of new LED mixed light, blending technical LED light source, unit volume is very small, on many occasions clearly merits, but sometimes also shortcomings. Such as: the LED-type light on the plane, there are usually spot-beam and uneven blend phenomenon. At present, the mixed light, blending the question is: mixed light, blended with the uniform level of transparency of contradictions. This issue is also hindered the development of LED, primarilyfor materials, the need to capture the landscape LED lamps have a very important practical significance.To enter the field of LED lighting, lighting technology is a revolutionary leap. LED lighting on the Green's historic contribution to the development, will be silk-ho in line with the times from the tube to the transistor era leap, even as transistors for evaluation by leaps and bounds to the changes in the same large-scale integrated circuits, no exaggeration.In landscape lighting, LED has a more unique advantages, can be confident that, LED lamps landscape will be more interdisciplinary fusion along the road, toward the arts and intelligent, flexible in the direction of rapid development.LED在景观照明中的应用LED光源除了无汞、节能、节材、对环境无电磁干扰、无有害射线五项优点之外,在照明领域中,特别是在景观照明中,还有很多优势。

博物馆展厅设计中LED光源的运用

博物馆展厅设计中LED光源的运用在博物馆展厅设计中,LED光源被广泛运用。
LED(Light Emitting Diode)是一种具有高亮度、低能耗、寿命长、体积小、环保等优点的新型照明光源,正逐渐取代传统的照明方式在博物馆展厅设计中扮演着重要角色。
下面将从四个方面探讨LED光源在博物馆展厅设计中的应用。
首先,LED光源作为主要照明光源,可以提供良好的照明效果。
博物馆展厅要求照明效果柔和、均匀,以保证观众在观展时能够清晰地看到展品细节。
与传统的照明方式相比,LED光源具有发光均匀、无闪烁、色彩还原度高等优势,能够更好地满足博物馆展厅设计的要求。
此外,LED光源的亮度和色温可根据不同展品的特点进行调节,从而更好地展示展品的真实色彩。
其次,LED光源能够实现多种灯光效果,增强展品的艺术感和观赏性。
博物馆展厅不仅仅是展示展品,更是通过灯光的设计和运用,为观众营造出艺术氛围和观展体验。
通过调整LED光源的颜色、亮度、光线角度等参数,可以实现多种灯光效果,如聚焦照明、投影照明、柔和照明等,从而使展品在不同的灯光下呈现出不同的效果,让观众对展品产生更多的感受和理解。
第三,LED光源在博物馆展厅中的应用还可以实现环境照明和装饰照明的双重效果。
博物馆展厅不仅要保证展品的展示效果,还要通过环境照明和装饰照明来塑造特定的展览氛围。
LED光源的灯具种类繁多,可以根据展厅的设计风格和展品特点选择合适的灯具进行装饰。
比如,在古代艺术品展厅中使用仿古灯具,可以提高观众的身临其境感;在科技展厅中使用现代感强的灯具,可以增强展品的科技感。
最后,LED光源具有低能耗、寿命长、维护成本低等优势,符合博物馆展厅节能环保的发展趋势。
传统的照明方式常常需要大量能源,并且照明设备的维护和更换成本较高。
而LED光源的能耗较低,寿命长达数万小时,不仅可以节约能源和减少维护成本,还可以减少对环境的污染。
对于博物馆展厅来说,这意味着能够更好地控制运营成本,同时也符合社会和环境的可持续发展要求。
LED照明在城市景观亮化中的应用

LED照明在城市景观亮化中的应用摘要:景观亮化又叫做夜景亮化,是指充分发挥人工灯光的装饰及造景作用,来形成一定的景观,并打造出独特的夜间空间,进而提供一种视觉享受。
伴随先进科技的飞快进步,LED在市政景观亮化中,起到了很关键的照明作用,并且正在逐步代替传统光源。
基于此,本文概述了LED,并且探讨了在市政景观亮化中,LED照明的优势作用及有效的应用措施。
关键词:有效应用;景观亮化;LED照明伴随现代城市日益增大夜景亮化需求,市政景观方面也涌现出越来越多的亮化工程,并逐步发展成为一种产业[1]。
但是,传统照明体系在环保、节能、色彩等上,现已很难满足城市亮化景观方面的要求。
而作为固体半导体类型的发光器件,LED照明表现出很好的节能环保等性能,所以逐步取代了景观亮化中的传统照明[2]。
现阶段,LED照明正在不断改进优化LED技术,令LED光源变得更加实用,所以在市政照明工程中LED日益推广应用,极大地丰富了城市夜景。
一、LED的概述LED作为发光二极管,属于固体半导体类型发光器件,其中的半导体固体芯片充当的是发光材料[3]。
在LED两端施教正向电压,用以复合半导体内存在的少数、多数截流子,并且放出多余的能量,进而诱发光子发射,形成色彩丰富多样的光。
作为前景一片光明的新光源之一,LED尽管当前还无法完全代替其他功能照明光源,但是,在市政景观照明上,现已呈现出非常强大的优势特点。
二、市政景观亮化中LED照明的优势特点现阶段,LED照明呈现出一系列的优势特点,如小体积、高效、可调颜色、智能化控制等[4]。
相较于传统景观照明,LED照明体现出以下优势特点:①LED照明用的是低压电源,电压主要位于3-24V区域,可很方便地防范火灾,并且还用到了冷发光科技,要较普通照明具有明显更少的发热量,有益于植物生长。
②LED出光存在一定程度的方向性,可很好地控制光的整体分布、缩减室外景观逸散光。
尤其是针对植物景观,所需的照明除了宜室外光环境气氛适宜外,还需有效控制光污染,所以非常适合LED照明。

LED在景观照明中的应用LED光源除了无汞、节能、节材、对环境无电磁干扰、无有害射线五项优点之外,在照明领域中,特别是在景观照明中,还有很多优势。
如:低压供电——无高压环节,为了绝缘的开销要小得多,可靠性高;附件简单——无启动器、镇流器或超高压变压器;结构简单——具有固体光源的最大优点,不充气,无玻璃外壳,无气体密封问题,耐冲击;可控性好——响应时间快(微秒数量级),可反复频繁亮灭,基本无惰性,不会疲倦;色彩纯厚——由半导体PN结自身产生色彩,纯正,浓厚;色彩丰富——三基色加数码技术,可演变任意色彩;轻质结构——节材,节约费用;对灯具强度和刚度要求很低;——体积小巧大的LED灯具可看成由LED细胞组成,最小的LED仅为平方毫米数量级或更小;柔性化好——LED 光源的精巧,使LED能适应各种几何尺寸和不同空间大小的装饰照明要求,诸如:点、线、面、球、异形式,乃至任意艺术造型的灯光雕塑;可见,LED不愧为21世纪绿色照明的骄子。
LED景观装饰灯具研发的特点由于LED具有上述一系列优势,LED在景观灯具的研发方面主要有以下几个方向:园林灯,步道灯,地埋灯,小型射灯,草坪灯,快车道分道地灯,壁灯等。
光源采用LED,并结合变幻控制,可升级对景观的烘托,使其更具艺术品位。
非标异形景观灯具的开发,在景观照明中,灯具安装要保护景观和环境,防止灯具有碍观瞻,要做到白天美化,夜幕下艺术亮化。
这就需要灯具的结构与安装因景制宜,因建筑特色制宜,很多标准灯具是满足不了以上要求的。
LED灯具设计的柔性化,特别适合因景制宜的非标灯具设计,使景观照明与景观协调,达到美化环境的新水平。
艺术化景观灯具开发灯具本身就是一种造型艺术,而LED光源将更能使景观灯具的艺术创意达到更高境界。
由于LED的可控性好,色彩丰富,与微电子技术实现智能化控制,可以构思出各种色彩缤纷、动感节奏欢快、旋律优美的景观灯具。
如:LED霹雳灯,比气体放电型霹雳灯要长寿得多,又不易损坏,而且色彩丰富。
又如:LED风车灯,只需微机智能控制,就可实现“无风时”飞速旋转,并且还能实现自动变速和换色的美妙变幻。
类似这样的构思,只要有灵感,都能实现。
灯光雕塑类的开发,任何仿真的、仿生的、漫画的、卡通的、商业的、旅游的等等的各种灯光雕塑,均可结合LED和声响技术以及微电子控制,必要时还可再加上机电一体化技术,开发出一系列吸引人们眼球的景观灯光雕塑。
LED景观照明的智能化控制技术,LED景观照明的智能化控制技术,属于模拟或数码技术、或微机控制技术领域,多数为紧凑型或嵌入式系统。
特点:可靠性高,价格优;变化花样繁多;既有单灯控制,又有群控模式;非标设计很多;长或超长灯具多(如:长光带,很多壁灯线状布局情况);与LED显示屏技术有很多不同之处。
根据景观美化的要求,变幻控制模式,给人以丰富多彩,旋律优美,节奏欢快的感受,有时芯至给人以撼动人心的强烈刺激。
根据LED可控性好,色彩丰富的特点,色彩构成几乎无限。
按照三基色原理加数字灰度控制技术,原理上可演变出几乎超越大自然存在的任意色彩。
例如:三基色LED,如只采用二级灰度控制,即:明和暗,可实现8种色彩演变;又如:三基色LED,采用三级灰度控制,即:明、中、暗,可实现27种色彩变幻;再如:三基色LED,如都采用八位数码的灰度控制,色彩种类竟达到了令人吃惊的程度,达1677万种,连每一种颜色的名字你都来不及命名。
目前,LED灯具的电子控制结构,主要有五大类或更多:单灯控制、群灯控制、长或超长跨距灯控制、声响控制、感应控制。
就寿命表现度而言,硅树脂可以达到延长白光LED使用寿命的目标,甚至可以达到4万小时以上的使用寿命,但是,是不是真的适合用来做照明的应用就还有待研究,因为硅树脂是具有弹性的柔软材料,所以在封装的过程中,需要特别注意应用的方式,而来设计出最适当的应用技术。
对于未来应用的方面,提高白光LED的光输出效率将会是决胜的关键点。
白光LED的生产技术,从过去的蓝色LED和黄色的YAG荧光体的组合,开发出仿真白光的目标,到利用三色混合或者使用GaN材料,开发出白光LED,对于应用来说,已经可以看的出将会朝向更广泛的方向扩展。
ﻫ另外,白光LED的发光效率,这些年已经有了不错的的发展,日本LED照明推进协会目标是,期望能够预计在2009年达到100lm/w的发光效率,而事实上,有相当多的业者都在朝向这方面开发,所以预计在数年内,100lm/w发光效率就能够实际上商业化应用。
LED微电子控制电路优化设计的焦点在于:可靠、价优,采用通用元器件,来源丰富。
对于长或超长跨距灯的控制除以上要求,还要有以下优点,如:数十米,百米乃至千米以上的光带或线状布局的点光源。
优化设计的目标还有:在运动控制上,要色彩丰富,变幻多姿,既含跳变,又有渐变,同时还要最大限度地减少讯导线。
LED发展中要攻克的主要问题LED进入照明领域是新生事物,具有划时代的意义。
但是,与任何新技术一样,LED还存在一些急需完善的方面。
1)研发LED高功率点光源国际上,Phlips、GE、OSRAN等大公司都有双端的球形HID产品,这是目前世界上最先进的大功率HID光源,特别是Phl ips公司基于这种光源的体育场馆灯具,灯具效率和配光曲线非常优秀。
尽管LED有很多独特的优势,但目前这方面却是空白。
高功率密度的点状光源对用于半导体发光原理的LED可能是一个很大的技术难点。
2)发展高效率、高功率因数、价优的紧凑型模块化LED电源,LED供电简便,既可直流供电,又可脉冲供电。
没有HID和高压霓虹灯的一系列麻烦。
目前,低效率的供电系统,拖了LED的后腿,节能水平大打折扣。
开关电源从70年代的20KHZ的标准到目前已达到1MHZ以上的软开关技术,问题关键在于如何做到质优价廉。
3)发展新型LED混光、混色技术LED光源,单位体积很小,在很多场合明显是优点,但有时又是缺点。
如:在LED平面型光源上,通常出现点状光斑以及混色不均匀现象。
目前,混光、混色存在的问题是:混光、混色的均匀水平与透光率的矛盾。
这个问题也是阻碍LED发展的因素,主要是材料的原因,急待攻克,对LED景观灯具实用性有很重要的意义。
LED进入照明领域,是照明技术的革命性飞跃。
LED对绿色照明发展的历史性贡献,将丝豪不逊于从电子管时代到晶体管时代的飞跃,即使评价为如同晶体管跨越到大规模集成电路的巨变一样,也毫不夸张。

Such as:low-voltage power supply - no high-pressure areas, inorder toinsulationcosts much less,highreliability annex simple- no s tarter, ballastor EHV transformer; simple structure- a solid sourceof thegreatestadvantages ,Non-carbonated,non-glasscase,nogas sealing problems, impact resistance; control lablegood -fast response time(microsecondorder of magnitude)can berepeated frequently-out,basically inert, will not be tired; color Chunhou-- SemiconductorPN junctionproduce their own color, pure, strong, rich colors -plusthree primary colors of digital technology, evolution of arbitrary color; light structure -wood,cost-saving; lampson strength andstiffness requirements of very low---- Thecompact size oftheLED lamps can be seen as t heLED cells, only the smallest LED mm2 orderof magnitude or less;flexible good- LEDlightsource ofthecompact, LED canadapt toallkinds of different size and geometry ofspa ce size The decorativelighting requirements, suchas: point, li ne, surface,theball, different forms,andany form ofart lighting sculpture;visible, LED isworthy ofagreen lightingof the21st century proud. ﻫLEDdecorative landscapelighting researchand development duetothecharacteristics of the LEDwith a series of advantages,LED lamps in the landscape ofresearch and development mainly inthe followingdirections: gardenlights,pathlights,lamps and buried,smallspotlights, Caoping Deng,the Fast-TrackRoad Lamps, wall lamp,and so on. Source use LED, combinedwithchanges in control,upgradingthe Hongtuo onthe landscape, making themmore artistic tastes. Non-standard profiled the development of landscape lighting, landscape lighting, lampsinstalled to protectthelandsc ape andenvironment,the preventionof lighting thevisual impact, in order to beautify theday, under the artistic Lianghua night. Thi srequires installationof lamps because of the structureand system to King, thearchitecturalfeatures to the system,many can not meetthe standardlamps is more thanrequir ed.LED lampsdesigned flexible, especially for thesystem toKing because of the non-standardlighting design, landscape lighting and visual coordination,beautifythe environment toachieveanewlevel.Art of Landscape Lightinglamps isitself a developmentofVisual Arts,and theLEDlight sourcecan be morecreative artof landscape lightingto a higher realm. As thecontrollable LED good,richcolors,andmicroelectronic technologyintelligent control, to all kinds of ideas canbecolo urful and excitingjoyfulrhythm,melodybeautiful landscape lighting. Such as: LED lights Perak, Perak than the gas-dischargelamp sto be much morelongevity, not damaged, and richcolors. Another example: LED lights winds,just intelligentcomputer control,we can achieve "Nowind atthe" rapid rotation, andalso enables automatic transmissionandfor thewonderfulcolor changes. Similar ideas, aslong as theinspiration,can achieve.Lighting sculpture categoryof development, any of the simulation, bionics, comics, cartoons, commercial,tourismand soonthevariouslighting sculpture, and sound can be combine dLED technology and microelectronics control, when necessary,to gether with Onthemechanical and electrical integrationtechnology, developedto attractpeople's attentiona series oflandscape lighting sculptures.LED lighting landscape ofintelligent control technology, LEDlightinglandscape of intelligent control technology,adigitaloranalog technology, orcomputer controltechnology, forthemost compact or embedded systems.Characteristics: highreliability,excellentprices; many changes inpatterns;existing single-lightcontrol, another group control mode; manynon-standarddesign; long long lamps or more (such as: long-zone, manyWall linearlayout); LED display technology and a lot ofdifference. ﻫAccording to thel andscaping requirements, changes in control mode,givesto richand colorful, beautiful melody,rhythm joyful feelings,sometimes to shake the core togive people a strong boost.Accordingto LEDcontrollable, and thecharacteristics ofrich color, color constitute almost unlimited. In accordancewith theprinciples of the three primary colors andgray-scale digital control technology, on the principle of evolution to be almost bey ondthe arbitrary nature color.For example: threecolorLED, such as using only two gray-scale control, namely: the dark and can achieve eightkinds of color evolution;Another example:three color LED, a three-gray control,namely:that in the dark, To achieve 27 kinds of color changes; Anothere xample:three color LED,such as theuse of the eight digit alcontrol ofgray,color categorieshas reachedan alarminglevel, reaching 16.77 million kinds, even the names of everyc olor youare too lateNamed.Currently,LED lampselectronic control structure, there arefive or morecategories:single-lightcontrol, light control group, or super-long span of control oflights,noisecontrol, s ensor control.ﻫOn the performance of life, thesiliconecan be achievedto extend the service lifeof white LED target,or evenreach more than 40,000hours of life, but is not really suited to d othe lighting onthe application ofresearch still needs to be, because thesiliconeIs a flexible soft material,so in the packaging process,the need to payspecial attention to applica tion of the way,from designing the mostappropriateapplication of technology.For the future of thearea,improve white LED light output efficiency willbe key to winning the point.White LEDproduction techniques,from a blue LED and a yellow YAG phosphormix, d eveloped a simulation ofthe white target, the useof colouror mixed use of GaN materials, developedawhiteLED,the applicationshave already Will be readout inthe direction towardsamore extensive expansion.In addition, the luminous efficiency white LED,which hasbe en good in the developmentof LED lightingpromoting the Japan Association goal is to look forward to in 2009is expectedtoreach 100 lm/w the luminous efficiency, and in fact, a considerable number of Intheindustry towards thedevelop ment ofthisarea,isexpected inthe nextfew years,100lm /w luminousefficiencycan actually commercial applications.LEDmicro-electroniccontrolcircuitdesign optimizationof the focus is: reliable, theprice ofdistinctions, using common components,sources of wealth. The length or lon gspan of controllights inadditionto theaboverequirements,butalso has the following advantages, such as: Shu Shimi, 100 metersand 1,000 meters above the band orlinear layout ofthe pointsource. Optimal Design of theobjectives are:motion control, it is necessary to colourful,bringingamazingvisual i mages,both oftransition, have graded,butalso to minimize - wire.LED development ofthe main issues tobe tackled into the LED lighting is new tothe area, is of epoch-makingsignificance. However, as with any new technology, LEDthere arest ill some areasin urgent needofimprovement.1)research and developmentof highpowerLED light source at the international level,Phlips,GE,OSRAN and otherbig companies have double-sphericalHID products, which iscurrently the world's most advanced high-power HIDlight sources,especiallyPhlipscompanybasedon thissource of sportsVenues lamps,lamp efficiency and with verygood light curve. Although LED manyunique advantages,but this area is blank.High-powerdensity point for the semiconductorLEDlightsource on the principle ofLEDmaybe a lot oftechnical dif ficulties. ﻫ2)the development of high efficiency, high power fa ctor,the price of gifted compact modularpower LED,LED power supply is simple, can DCpowersupply, power supply can pulse.HID noneonlights and aseries of high-pressuretr oubles. Atpresent, the low efficiency of the power supplysystem,dragged downby the LED,greatlyreducedthe levelofenergy. Switching power supply from the1970s to 20KHZthe standardhasnow reachedmore than1MHZ the soft-switch technology,the cru xof the problem is howtoachievequality and cheap.3) the developmentofnew LED mixed light,blending technical LED light source, unit volume isvery small, on many occasionsclearly merits, but sometimesalso shortcomings. Such as: the LED-type light on the plane, there are usually spot-beam and unevenblend phenomenon. Atpresent, themixed light, blending thequestion is: mixedlight, blended with the uniform level oftransparency ofcontradictions.This issue is alsohindered the developmentof LED, primarily for materials, the needto capturethe landscape LED lamps have aver yimportantpractical significance. ﻫTo enterthe field ofLED lighting, lighting technologyis a revolutionary lea p. LED lightingon the Green's historic contribution to the de velopment, willbe silk-ho in line withthetimesfromthe tube to thetransistor era leap, even astransistorsfor evaluation byleaps andbounds to the changesin thesamelarge-scale integra tedcircuits, noexaggeration. ﻫIn landscape lighting,LED has a more unique advantages, can be confident that, LED lamps landscape will be moreinterdisciplinary fusion along the road, toward theartsand intelligent,flexible in th edirection ofrapid development.Author: WangBin."LEDlight source in the applicationof landscape design."Lighting Design, May20,2008http://hi.baidu.com/z.mshe。
