LED調光器是一種電子裝置,LED調光器它改(gai)變照明裝置中光源的光通量並調節(jie)照明水平。LED調光器的作用是將光線調節到不同的水平。通過降(jiang)低(di)或(huo)增加RMS電壓來促(cu)進(jin)不同強(qiang)度(du)光輸出所(suo)產生(sheng)的光的平均功率。這(zhe)一規(gui)定(ding)旨(zhi)在(zai)控(kong)製照明,盡(jin)管(guan)可變電壓裝置可(ke)用於各(ge)種(zhong)目的。

在今(jin)天(tian)的LED行(xing)業中,我目前看(kan)好的是LED調光器技術和LED驅動電源。LED驅動電源主要(yao)是麵向(xiang)LED路燈的電源。這一(yi)次草莓视频色版app將專(zhuan)注於LED調光。LED調光器技術主要包括(kuo)以下幾(ji)個方(fang)麵:這種發展在白熾(chi)燈調光技術上(shang),白(bai)熾燈(deng)是純(chun)阻抗負載,可以實現調光,但(dan)對(dui)於(yu)LED來(lai)說(shuo)並不實(shi)用,從兼(jian)容(rong)可控矽調光電源來說,效率很低,通常很難(nan)達(da)到(dao)80%,這與(yu)LED的節能目(mu)的是相(xiang)抵(di)觸(chu)的,其次,很(hen)難達到高功率因(yin)數,再(zai)一次(ci),隻(zhi)在單一輸入電壓下工(gong)作,這種調光技術(shu)肯(ken)定會因為(wei)白熾燈泡的淘汰而消亡(wang),但由(you)於市(shi)場(chang)滲透(tou)率高,它還(hai)會存在一段時間。


線性(xing)調光采(cai)用恒(heng)流芯(xin)片(pian)專用調光腳(jiao),調節LED的電流(liu),達到調光的目的,這種技術很好(hao),但接線複(fu)雜(za),不利(li)於熒(ying)光燈照明,很多燈都(dou)采用這種方法。PWM調光這種方法類(lei)似於線性調光,和線性調光一起占據(ju)了台燈調光的大部分。這種PWM調光也(ye)非常受用戶(hu)和客(ke)戶的歡(huan)迎(ying)。遠程(cheng)調光加成外部遙控和無(wu)線遙控兩種,實現起(qi)來比較複雜,但是可以(yi)達到改變色溫的效(xiao)果(guo),顏(yan)色等調光方法都無法(fa)達到,主要用於麵板(ban)燈調光,也有一些燈泡(pao)燈采用一些(xie)調光方法。

分(fen)段調光器,該調光器模(mo)式(shi)是利用牆上的開關(guan)在規定的時(shi)間(jian)內(nei)開(kai)關來達到移動光源的目的,這種方法的優點是不需(xu)要額外(wai)的移動光源組(zu)件,根(gen)據現有的安裝,每盞燈都可以實現調光,另一種,因為調光完(wan)全由內部電源開關芯片控製,全電壓範圍(wei),工作時無論(lun)在什(shen)麽樣的亮度下,都可以達到高效率(lv)和(he)高功(gong)率因數(shu),缺點(dian)是隻能根據設定的亮度進行循(xun)環調節,無法實現無級(ji)調光,而(er)且是非常(chang)少(shao)的這類類型的IC,而且目前的調節方麵也不是很理(li)想(xiang),但我認為隨(sui)著技術的成(cheng)熟(shu),IC廠(chang)家會更(geng)加(jia)完善,個人(ren)感覺,這種調光技術,會成為未(wei)來調光技術的主流。
