七彩燈帶控制器原理常用(yong)(yong)(yong)(yong)的(de)裝(zhuang)飾燈(deng)帶(dai)(dai)有兩種，一(yi)種是使用(yong)(yong)(yong)(yong)傳(chuan)統燈(deng)泡作為發(fa)光(guang)材(cai)(cai)料．還(huan)有一(yi)種是使用(yong)(yong)(yong)(yong)較(jiao)為先進的(de)三色(se)LED發(fa)光(guang)二極管作為發(fa)光(guang)材(cai)(cai)料．后者(zhe)不僅節能效(xiao)果顯著，還(huan)有經久耐用(yong)(yong)(yong)(yong)、維護(hu)工作少等特點。現在(zai)裝(zhuang)飾燈(deng)帶(dai)(dai)一(yi)般都使用(yong)(yong)(yong)(yong)后者(zhe)。筆者(zhe)最近(jin)剖析(xi)了一(yi)款用(yong)(yong)(yong)(yong)得比(bi)較(jiao)好的(de)七(qi)彩閃光(guang)LED燈(deng)帶(dai)(dai)控(kong)制電路，見圖1。 圖中電(dian)路(lu)使用(yong)了(le)專用(yong)七(qi)彩LED閃光(guang)(guang)控制芯片(pian)HL081LF，HL081是(shi)采用(yong)CMOS工(gong)藝制造的(de)同步(bu)七(qi)彩閃光(guang)(guang)集成電(dian)路(lu)．配合(he)紅綠藍(lan)三基色(se)高亮發(fa)光(guang)(guang)二(er)極管，可(ke)表現出絢(xuan)麗(li)多彩的(de)變色(se)光(guang)(guang)效(xiao)果．廣(guang)泛用(yong)于(yu)玩具(ju)和其他場(chang)合(he)．如(ru)草坪燈(deng)(deng)、廣(guang)場(chang)燈(deng)(deng)、護攔燈(deng)(deng)等城市燈(deng)(deng)光(guang)(guang)裝飾場(chang)合(he)。HL081芯片(pian)的(de)特性：工(gong)作電(dian)壓3-5.5V，工(gong)作電(dian)流小于(yu)300uA，具(ju)有(you)模(mo)(mo)式(shi)設置端(duan)(duan)(duan)。有(you)四種變化模(mo)(mo)式(shi)。具(ju)體模(mo)(mo)式(shi)如(ru)下表所示，適用(yong)于(yu)交(jiao)流供(gong)電(dian)，通過同時上(shang)電(dian)，實現同步(bu)閃光(guang)(guang)功能。HL081的(de)管腳(jiao)(jiao)(jiao)排列，①腳(jiao)(jiao)(jiao)zc，50／60Hz輸入，②腳(jiao)(jiao)(jiao)VDD，電(dian)源(yuan)正，③腳(jiao)(jiao)(jiao)BL，藍(lan)燈(deng)(deng)輸出端(duan)(duan)(duan)，④腳(jiao)(jiao)(jiao)GL，綠燈(deng)(deng)輸出端(duan)(duan)(duan)，⑤腳(jiao)(jiao)(jiao)RL，紅燈(deng)(deng)輸出端(duan)(duan)(duan)，⑥腳(jiao)(jiao)(jiao)GND，電(dian)源(yuan)地，⑦腳(jiao)(jiao)(jiao)s1，模(mo)(mo)式(shi)設置端(duan)(duan)(duan)，⑧腳(jiao)(jiao)(jiao)SO，模(mo)(mo)式(shi)設置端(duan)(duan)(duan)。Hcl06D是(shi)4A、400V高靈敏(min)度(du)直流可(ke)控硅。HL081芯片(pian)輸出控制可(ke)控硅從而控制三色(se)發(fa)光(guang)(guang)二(er)極管以一(yi)定的(de)發(fa)光(guang)(guang)規律發(fa)光(guang)(guang)。 圖(tu)(tu)2是(shi)(shi)(shi)閃(shan)光(guang)燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)的示(shi)意圖(tu)(tu)。燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)控(kong)(kong)制器(qi)使用220V交(jiao)流電(dian)，它(ta)與燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)有四根(gen)連(lian)線，分(fen)別是(shi)(shi)(shi)ABCD和A’B’C’D一(yi)(yi)(yi)一(yi)(yi)(yi)對應(ying)，燈(deng)(deng)(deng)帝以米(mi)為單(dan)位(wei)(wei)．圖(tu)(tu)1所(suo)示(shi)的控(kong)(kong)制器(qi)上(shang)標為50米(mi)．說明一(yi)(yi)(yi)個(ge)(ge)(ge)(ge)控(kong)(kong)制器(qi)可以驅(qu)動50米(mi)的閃(shan)光(guang)燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)，燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)不(bu)(bu)能(neng)(neng)隨便剪斷(duan)，一(yi)(yi)(yi)般在(zai)能(neng)(neng)剪的位(wei)(wei)置上(shang)的側面有個(ge)(ge)(ge)(ge)剪刀的標志。如要剪只(zhi)能(neng)(neng)在(zai)該地方剪，否(fou)則(ze)燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)的前(qian)段或后段總有部分(fen)不(bu)(bu)能(neng)(neng)正常(chang)點亮(liang)。每一(yi)(yi)(yi)米(mi)燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)中(zhong)集成有若干個(ge)(ge)(ge)(ge)圖(tu)(tu)2所(suo)示(shi)的閃(shan)光(guang)燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)單(dan)元。各(ge)個(ge)(ge)(ge)(ge)單(dan)元之間是(shi)(shi)(shi)并(bing)(bing)聯(lian)(lian)連(lian)接的，而一(yi)(yi)(yi)般每個(ge)(ge)(ge)(ge)單(dan)元中(zhong)各(ge)色發(fa)光(guang)管(guan)的個(ge)(ge)(ge)(ge)數和限流電(dian)阻并(bing)(bing)不(bu)(bu)一(yi)(yi)(yi)樣(yang)．根(gen)據外觀看．同一(yi)(yi)(yi)根(gen)燈(deng)(deng)(deng)帶(dai)(dai)(dai)(dai)中(zhong)一(yi)(yi)(yi)種光(guang)色的是(shi)(shi)(shi)四個(ge)(ge)(ge)(ge)二極管(guan)串聯(lian)(lian)，而另一(yi)(yi)(yi)種光(guang)色的卻(que)是(shi)(shi)(shi)8個(ge)(ge)(ge)(ge)二極管(guan)串聯(lian)(lian)。如按圖(tu)(tu)1所(suo)示(shi)．由于發(fa)光(guang)模式(shi)的設置已固定，三色發(fa)光(guang)管(guan)交(jiao)迭(die)閃(shan)亮(liang)，很(hen)漂亮(liang)。 ’
七彩燈帶工作原理七彩LED發光原理 要(yao)想(xiang)知道七彩(cai)LED發光(guang)(guang)(guang)原(yuan)理(li)(li)，首先來認識一下紅(R)、綠(G)、藍(lan)(lan)(B)三(san)基(ji)色(se)(se)(se)，由(you)這三(san)種(zhong)(zhong)(zhong)顏(yan)色(se)(se)(se)經過不(bu)同(tong)組合可(ke)以得到(dao)其他(ta)不(bu)同(tong)的(de)顏(yan)色(se)(se)(se)。例如紅光(guang)(guang)(guang)和(he)綠光(guang)(guang)(guang)同(tong)時點(dian)(dian)(dian)亮時,紅綠兩(liang)種(zhong)(zhong)(zhong)光(guang)(guang)(guang)混合成黃色(se)(se)(se)，變色(se)(se)(se)燈(deng)的(de)變色(se)(se)(se)原(yuan)理(li)(li)是(shi)通過三(san)種(zhong)(zhong)(zhong)基(ji)色(se)(se)(se)LED分(fen)別點(dian)(dian)(dian)亮兩(liang)個LED時,它可(ke)以發出黃、紫、青色(se)(se)(se)(如紅、藍(lan)(lan)兩(liang)LED點(dian)(dian)(dian)亮時發出紫色(se)(se)(se)光(guang)(guang)(guang))，若(ruo)紅、綠、藍(lan)(lan)三(san)種(zhong)(zhong)(zhong)LED同(tong)時點(dian)(dian)(dian)亮時,它會產生(sheng)白(bai)光(guang)(guang)(guang)。如果有(you)電路能(neng)使紅、綠、藍(lan)(lan)光(guang)(guang)(guang)LED分(fen)別兩(liang)兩(liang)點(dian)(dian)(dian)亮、單獨點(dian)(dian)(dian)亮及(ji)三(san)基(ji)色(se)(se)(se)LED同(tong)時點(dian)(dian)(dian)亮,則他(ta)就能(neng)發出七種(zhong)(zhong)(zhong)不(bu)同(tong)顏(yan)色(se)(se)(se)的(de)光(guang)(guang)(guang)來,于(yu)是(shi)就出現了七彩(cai)LED燈(deng)的(de)這種(zhong)(zhong)(zhong)現象(xiang)，隨著它們疊(die)加比例的(de)不(bu)同(tong)，則產生(sheng)不(bu)同(tong)的(de)色(se)(se)(se)彩(cai)。 七(qi)(qi)(qi)彩(cai)(cai)LED有兩個(ge)引腳，里面封(feng)裝的(de)(de)3個(ge)芯(xin)片（一(yi)(yi)(yi)(yi)(yi)般(ban)是(shi)(shi)(shi)紅(hong)(hong)(hong)，綠(lv)，藍，三種(zhong)(zhong)(zhong)(zhong)）內置有IC，直接(jie)通電(dian)就可(ke)以自(zi)變(bian)顏(yan)色(se)(se)紅(hong)(hong)(hong)綠(lv)藍交(jiao)替變(bian)色(se)(se)，一(yi)(yi)(yi)(yi)(yi)般(ban)是(shi)(shi)(shi)透明樹脂封(feng)裝，控(kong)制(zhi)變(bian)色(se)(se)的(de)(de)IC，當通電(dian)后(hou)通過里面的(de)(de)IC來(lai)控(kong)制(zhi)變(bian)色(se)(se)。因此七(qi)(qi)(qi)彩(cai)(cai)LED實際是(shi)(shi)(shi)3種(zhong)(zhong)(zhong)(zhong)顏(yan)色(se)(se)，一(yi)(yi)(yi)(yi)(yi)般(ban)是(shi)(shi)(shi)紅(hong)(hong)(hong)綠(lv)藍，之(zhi)所以是(shi)(shi)(shi)七(qi)(qi)(qi)彩(cai)(cai)，有如下排(pai)列:紅(hong)(hong)(hong)綠(lv)藍、紅(hong)(hong)(hong)綠(lv)混合(he)、紅(hong)(hong)(hong)藍混合(he)、綠(lv)藍混合(he)、紅(hong)(hong)(hong)綠(lv)藍混合(he)。七(qi)(qi)(qi)彩(cai)(cai)LED燈分為兩種(zhong)(zhong)(zhong)(zhong)，一(yi)(yi)(yi)(yi)(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)(shi)七(qi)(qi)(qi)彩(cai)(cai)快閃LED:一(yi)(yi)(yi)(yi)(yi)般(ban)一(yi)(yi)(yi)(yi)(yi)個(ge)變(bian)色(se)(se)周期(qi)是(shi)(shi)(shi)10-15S，另外一(yi)(yi)(yi)(yi)(yi)種(zhong)(zhong)(zhong)(zhong)是(shi)(shi)(shi)七(qi)(qi)(qi)彩(cai)(cai)慢閃LED：一(yi)(yi)(yi)(yi)(yi)般(ban)一(yi)(yi)(yi)(yi)(yi)個(ge)變(bian)色(se)(se)周期(qi)是(shi)(shi)(shi)25-56S。 led燈帶風扇遙控原理led燈(deng)帶控(kong)(kong)制(zhi)(zhi)原理，它是利(li)用(yong)智能燈(deng)光(guang)控(kong)(kong)制(zhi)(zhi)系統(tong)(tong)(tong)來(lai)進行(xing)控(kong)(kong)制(zhi)(zhi)與(yu)管理的(de)系統(tong)(tong)(tong)，它跟傳統(tong)(tong)(tong)的(de)照明燈(deng)相比可以(yi)(yi)使燈(deng)光(guang)自動重啟，調光(guang)，和很多一(yi)對一(yi)的(de)遙控(kong)(kong)以(yi)(yi)及燈(deng)光(guang)的(de)全方位管理，在智能燈(deng)光(guang)控(kong)(kong)制(zhi)(zhi)系統(tong)(tong)(tong)當中(zhong)有遙控(kong)(kong)，集中(zhong)遠程(cheng)等多種控(kong)(kong)制(zhi)(zhi)方式，甚至可以(yi)(yi)用(yong)我(wo)們家里的(de)電(dian)腦來(lai)對燈(deng)光(guang)進行(xing)調控(kong)(kong)，從而達到智能燈(deng)光(guang)的(de)節(jie)能環保方便的(de)功效。 燈帶原理燈帶的(de)工(gong)作原理源(yuan)于其(qi)構成(cheng)(cheng)與(yu)工(gong)藝，較早的(de)工(gong)藝是把LED焊接在銅線(xian)上(shang)面(mian)，再套(tao)上(shang)PVC管或(huo)者采用設(she)備直接成(cheng)(cheng)型，有圓形和扁(bian)狀兩(liang)(liang)種，其(qi)稱謂按銅線(xian)的(de)數量和燈帶的(de)形狀來(lai)區(qu)分，兩(liang)(liang)根線(xian)稱為二線(xian)，圓形就(jiu)在前面(mian)加上(shang)圓，即圓二線(xian)；扁(bian)形就(jiu)在前面(mian)加上(shang)扁(bian)字(zi)，即扁(bian)二線(xian)。 后來(lai)發展成(cheng)為(wei)采(cai)用(yong)柔(rou)性線路板即FPC來(lai)做載體，因其加工(gong)工(gong)藝更簡便，質(zhi)量更容易(yi)控制(zhi)，壽命更長，顏色和亮度更高 幻彩燈帶控制器的原理LED幻彩燈控(kong)制器原理： 幻彩(cai)燈(deng)珠是(shi)有(you)(you)三條(tiao)線的(de)，分別為R,G,B，也就(jiu)是(shi)紅，綠(lv)，藍，由(you)這(zhe)三種(zhong)顏色(se)可(ke)以變(bian)化出上萬(wan)種(zhong)的(de)色(se)彩(cai)，這(zhe)三條(tiao)線可(ke)以直(zhi)接接在對應的(de)RGB接線柱上，其中七彩(cai)燈(deng)條(tiao)還有(you)(you)一(yi)條(tiao)線是(shi)黃色(se)的(de)就(jiu)是(shi)回路來的(de)，這(zhe)條(tiao)線就(jiu)接在正極即可(ke)。 RGB的(de)線路是(shi)接在負(fu)極(ji)的(de)，回路是(shi)正極(ji)，控制器控制負(fu)極(ji)的(de)燈條，這(zhe)稱之為(wei)共陽的(de)。 以上就是小(xiao)編(bian)對于幻彩燈帶(dai)控制原理(七彩燈控制器接(jie)法(fa))問題和相關問題的解答了，希望對你有用 |
