Thyristor LED yog lwm txoj hauv kev zoo rau cov khoom uas muaj nyob rau niaj hnub no, uas yog siv los tsim cov teeb pom kev zoo. Qhov zoo ntawm LED: lub neej ua haujlwm ntev, kev siv hluav taws xob tsawg thiab qhov loj me me.
LED txoj cai ua haujlwm
Yog vim li cas rau qhov ci ntsa iab yog cov txheej txheem ntawm kev sib txuas ntawm qhov zoo thiab cov khoom tsis zoo hauv thaj chaw p-h-hluav taws xob. Thaj chaw no yog kev sib cuag ntawm ob yam khoom (semiconductors) nrog cov hluav taws xob sib txawv. Txhawm rau tsim lub ci ci, siv ntau txheej LED siv lead ua tsim. Nws qhov ci tuaj yeem nce ntxiv los ntawm kev siv lub zog muaj zog, tab sis nrog tus nqi loj ntawm lub zog tam sim no, lub diode yuav ua tsis tiav. Lub ci ci ntawm LED kuj tuaj yeem hloov kho downwards. Nws cov qauv tsim yog yooj yim heev, tab sis tib lub sijhawm, cov tuam ntxhab feem ntau tsis qhia qhov zais cia ntawm lawv cov khoom.
Hnub no, niaj hnub thyristor LED ua tau zoo heev, vim tias nws qhov ua tau zoo ntawm 60 txog 70%. Yog tias peb piv cov roj teeb incandescent (qhov ua tau zoo ntawm qhov tsuas yog 5-7%) nrog LED, tom qab ntawd qhov zoo duakaum lub sij hawm ib txwm. Lub sij hawm ntawm kev tshaj tawm kev ua haujlwm ntawm cov khoom siv teeb pom kev zoo uas siv lub thyristor LED yog kaum xyoo ntawm kev ua haujlwm tsis tu ncua. Kev txuag hluav taws xob thaum siv LED, piv rau LDS, yog kwv yees li 50%, thiab piv rau cov teeb pom kev zoo - 85%.
Lub teeb tso zis ntawm cov diodes niaj hnub tuaj yeem sib tw nrog MGL thiab HPS (nrog rau HPS). Qhov ntsuas no yog sib npaug rau 150 lm / W. Lub sijhawm them rov qab rau LED teeb yog 2-3 xyoos. Tom qab ntawd, rau kaum xyoo ntxiv, koj txuag tau 85% ntawm cov hluav taws xob siv txhua lub hlis.
LEDs. Features
LED, uas nws cov yam ntxwv tsis qis dua cov analogues, muaj cov txiaj ntsig hauv qab no:
- iav tsis siv hauv kev tsim cov LEDs, yog li cov teeb pom kev zoo no muaj lub zog siab, kev co kuj thiab kev ntseeg tau;
- LED tiv taus qhov poob qis thiab siv 0.4-0.6 A;
- thyristor LED ua haujlwm tau zoo nyob rau hauv cov xwm txheej hnyav, txawm tias qhov kub thiab txias heev.
Yuav kom khiav lub LED, xav tau ib tus choj kim kim diode, uas yog vim li cas tus nqi ntawm cov teeb pom kev zoo yav dhau los tau siab heev. Cov neeg tsim khoom tau daws qhov teeb meem no. Cov hluav taws xob hluav taws xob tau hloov pauv, thiab triac dimmers tau siv los hloov thyristor dimmers. Qhov tshwm sim yog ib qho cuab yeej uas muaj ob lub thyristors txuas nrog rau txoj kev sib luag. Vim qhov kev tsim kho tshiab no, tsis tas yuav siv tus choj diode niaj hnub no. Qhov kev txiav txim siab no ua raucov khoom pheej yig dua thiab ua kom muaj kev nyab xeeb thiab zoo hauv chav kawm ntawm cov khoom raws li thyristors.
Thyristor LED yog dav siv hauv kev lag luam teeb pom kev zoo. Nws lub neej ua haujlwm ntev, kev ntseeg siab thiab kev ua haujlwm zoo siab rau cov neeg siv khoom, vim tias cov chandeliers thiab lwm yam khoom siv nrog LED-backlight tsis yog tsuas yog kev lag luam xwb, tab sis kuj saib zoo nkauj heev.
