1．觸控式觸控式沙發燈臺燈的原理是內部安裝電子觸摸式IC，與臺燈觸摸處的電極片形成一個控制回路。當人體觸摸到感應電極片，觸摸信號借由脈動直流電產生脈沖信號傳送至觸摸感應端，接著觸摸感應端會發出一觸發脈沖信號，從而控制開燈；再觸摸一次，觸摸信號會再借由脈動直流電產生一脈沖信號傳送至觸摸感應端，此時觸摸感應端就會停止發出觸發脈沖信號，當交流電過零時，燈自然熄滅。不過，有時停電后或電壓不穩也會有自行亮起的情形，如果觸摸接收信號敏感度極佳的紙張或布也是可以控制的。2.亮度可調式可調沙發燈臺燈(deng)(deng)的工(gong)作原理(li)是由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)R2、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)位器(qi)RP1、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C組(zu)成阻(zu)(zu)容(rong)移相(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路，調節RP1，即可改變雙向晶(jing)(jing)閘管(guan)V的導通角，從而改變燈(deng)(deng)泡(pao)EL的亮(liang)度。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)R1為限(xian)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)。C的充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度還與并聯回路有關。在(zai)R1、RP2固定(ding)的情況(kuang)下，分(fen)流(liu)的大(da)小(xiao)(xiao)由光敏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)RL的阻(zu)(zu)值(zhi)來決(jue)定(ding)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)上升時，燈(deng)(deng)光亮(liang)度增(zeng)(zeng)加，RL阻(zu)(zu)值(zhi)變小(xiao)(xiao)，分(fen)流(liu)增(zeng)(zeng)大(da)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)C兩端電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)上升變慢，晶(jing)(jing)閘管(guan)V導通角減小(xiao)(xiao)，輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)減小(xiao)(xiao)，燈(deng)(deng)光亮(liang)度下降；反之，當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)下降時，RL阻(zu)(zu)值(zhi)增(zeng)(zeng)大(da)，分(fen)流(liu)減小(xiao)(xiao)，晶(jing)(jing)閘管(guan)導通角增(zeng)(zeng)大(da)，輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)增(zeng)(zeng)加，燈(deng)(deng)光亮(liang)度增(zeng)(zeng)加。燈(deng)(deng)光亮(liang)度就自動地穩定(ding)在(zai)設定(ding)值(zhi)。

1、移動方便：沙發燈落地燈不像一些主流類的比如吊燈或者吸頂燈，它們都是被安裝在房頂死死固定住的，一點也不能移動。而落地燈相比之下就非常方便了，只要是電線夠長，想放到哪里就放到哪里。而且非常的輕便甚至小孩子都能拿著隨便移動，尤其是在客廳和臥室，您想放客廳也可以，放臥室也可以。2、保養比較方便：沙發燈落(luo)地(di)(di)燈(deng)(deng)(deng)(deng)(deng)的(de)(de)(de)(de)(de)(de)(de)保養(yang)是(shi)(shi)(shi)非常方便的(de)(de)(de)(de)(de)(de)(de)，尤其(qi)是(shi)(shi)(shi)鐵藝(yi)落(luo)地(di)(di)燈(deng)(deng)(deng)(deng)(deng)，但是(shi)(shi)(shi)藤(teng)藝(yi)落(luo)地(di)(di)燈(deng)(deng)(deng)(deng)(deng)的(de)(de)(de)(de)(de)(de)(de)保養(yang)就(jiu)(jiu)(jiu)相(xiang)對(dui)難(nan)些(xie)，想一(yi)想那(nei)(nei)些(xie)大型(xing)的(de)(de)(de)(de)(de)(de)(de)主(zhu)流燈(deng)(deng)(deng)(deng)(deng)具(ju)吧，在保養(yang)的(de)(de)(de)(de)(de)(de)(de)時(shi)候(hou)肯定(ding)是(shi)(shi)(shi)愁(chou)壞很多人啊，要(yao)爬到(dao)那(nei)(nei)么(me)高的(de)(de)(de)(de)(de)(de)(de)地(di)(di)方進行拆卸，清(qing)洗完還要(yao)重新進行安(an)裝，費(fei)時(shi)又費(fei)力。再看(kan)看(kan)我(wo)們的(de)(de)(de)(de)(de)(de)(de)落(luo)地(di)(di)燈(deng)(deng)(deng)(deng)(deng)，結構簡單(dan)，我(wo)們在打(da)掃屋里(li)的(de)(de)(de)(de)(de)(de)(de)時(shi)候(hou)就(jiu)(jiu)(jiu)能(neng)很方面的(de)(de)(de)(de)(de)(de)(de)對(dui)它進行打(da)掃。如果(guo)真要(yao)是(shi)(shi)(shi)遇到(dao)難(nan)題，一(yi)個人一(yi)把螺絲刀(dao)就(jiu)(jiu)(jiu)能(neng)輕(qing)松搞定(ding)。3、節(jie)(jie)能(neng)省(sheng)(sheng)(sheng)電：其(qi)實對(dui)于節(jie)(jie)能(neng)省(sheng)(sheng)(sheng)電這方面呢，主(zhu)要(yao)的(de)(de)(de)(de)(de)(de)(de)還是(shi)(shi)(shi)要(yao)看(kan)使用的(de)(de)(de)(de)(de)(de)(de)光(guang)源(yuan)的(de)(de)(de)(de)(de)(de)(de)，如果(guo)是(shi)(shi)(shi)用白(bai)熾燈(deng)(deng)(deng)(deng)(deng)泡，那(nei)(nei)么(me)省(sheng)(sheng)(sheng)電也(ye)省(sheng)(sheng)(sheng)不到(dao)那(nei)(nei)里(li)去，但是(shi)(shi)(shi)相(xiang)對(dui)于其(qi)他(ta)的(de)(de)(de)(de)(de)(de)(de)燈(deng)(deng)(deng)(deng)(deng)飾，落(luo)地(di)(di)燈(deng)(deng)(deng)(deng)(deng)的(de)(de)(de)(de)(de)(de)(de)光(guang)源(yuan)就(jiu)(jiu)(jiu)比(bi)較少了(le)，再加上現(xian)在都是(shi)(shi)(shi)用led燈(deng)(deng)(deng)(deng)(deng)做光(guang)源(yuan)的(de)(de)(de)(de)(de)(de)(de)比(bi)較多的(de)(de)(de)(de)(de)(de)(de)，所以落(luo)地(di)(di)燈(deng)(deng)(deng)(deng)(deng)要(yao)比(bi)其(qi)他(ta)的(de)(de)(de)(de)(de)(de)(de)燈(deng)(deng)(deng)(deng)(deng)飾省(sheng)(sheng)(sheng)電很多，電費(fei)是(shi)(shi)(shi)每個家(jia)庭(ting)里(li)的(de)(de)(de)(de)(de)(de)(de)最平常的(de)(de)(de)(de)(de)(de)(de)開支(zhi)，但是(shi)(shi)(shi)能(neng)省(sheng)(sheng)(sheng)則省(sheng)(sheng)(sheng)啊。那(nei)(nei)些(xie)大型(xing)的(de)(de)(de)(de)(de)(de)(de)燈(deng)(deng)(deng)(deng)(deng)具(ju)只要(yao)打(da)開就(jiu)(jiu)(jiu)是(shi)(shi)(shi)幾百(bai)瓦的(de)(de)(de)(de)(de)(de)(de)功率。而落(luo)地(di)(di)燈(deng)(deng)(deng)(deng)(deng)的(de)(de)(de)(de)(de)(de)(de)功率就(jiu)(jiu)(jiu)顯(xian)得那(nei)(nei)么(me)微不足道了(le)，只有一(yi)個光(guang)源(yuan)，大的(de)(de)(de)(de)(de)(de)(de)功耗也(ye)就(jiu)(jiu)(jiu)是(shi)(shi)(shi)幾十瓦，是(shi)(shi)(shi)大型(xing)燈(deng)(deng)(deng)(deng)(deng)具(ju)的(de)(de)(de)(de)(de)(de)(de)十分之一(yi)，最適合(he)普通家(jia)庭(ting)了(le)。

用戶在選購簡約餐廳吊燈的話一般都是選用的是led沙發燈吊燈光，首先它的光源比較的亮，這樣才能夠吸引更多的顧客，同時如果采用的是歐式風格，在選購沙發燈吊燈的時候也要注意它的節能性。因為很多餐廳往往會選購led燈主要的原因就是，不僅它的發光效率比較的好，同時它的節能性也比較強。所以在很多簡約餐廳吊燈的擺放位置很重要。如果它的擺放位置比較好。那么吸引的用戶更多，現在很多餐廳，一般來說一個餐桌會成一個吊燈，沙發燈吊燈(deng)(deng)周圍會(hui)采取燈(deng)(deng)罩(zhao)，燈(deng)(deng)罩(zhao)的(de)形(xing)狀以(yi)(yi)及顏(yan)色不(bu)同，也會(hui)影(ying)響整個(ge)用餐氛圍。如果是情人餐廳(ting)的(de)話，一般來說(shuo)會(hui)采用紅色或者是微暗的(de)光芒，這樣可以(yi)(yi)烘托(tuo)出一種非常浪(lang)漫的(de)氛圍。所以(yi)(yi)用戶(hu)在選用簡約(yue)餐廳(ting)吊燈(deng)(deng)的(de)時候，要參考這些方面，盡(jin)量選擇(ze)符合(he)餐廳(ting)氛圍的(de)吊燈(deng)(deng)。
