Thyristor LED. Nta thiab ntsiab cai ntawm lub lag luam
Thyristor LED - qhov no yog ib tug zoo lwm txoj rau kev nthuav dav uas twb muaj lawm hnub no, uas yog siv nyob rau hauv qhov siv thiab ua teeb pom kev zoo pab kiag li lawm. Qhov zoo ntawm LED: thiav nyob rau hauv lub lag luam, tsis tshua muaj zog noj thiab me me qhov ntev.
Lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub LED
Yog vim li cas lub luminescence txheej txheem yog lub recombination ntawm qhov zoo them thiab tsis zoo them hais nyob rau hauv lub ph-txoj kev hloov tsam. Qhov no cheeb tsam yog cov interface ntawm ob ntaub ntawv (semiconductors) nrog txawv tam sim no conductivity muaj peev xwm. Yuav kom tsim tau ib tug kaj glow ntawm ib tug multilayer qauv ntawm cov LED nti. Lub brightness ntawm nws muaj peev xwm muab tau ntau zog los ntawm thov ib tug muaj zog nro, tab sis rau ib tug loj tus nqi tam sim no lub diode yuav puas ntsoog. LED brightness yuav tau tom nyob rau hauv cov kev taw qhia ntawm zuj zus lawm. Nws siv yog yooj yim heev, tab sis nyob rau tib lub sij hawm, feem ntau manufacturers tsis qhia ntawm daim card ntawm zus tau tej cov nws cov khoom.
Lub teeb tso zis ntawm niaj hnub diodes yuav lwv nrog IPF thiab HPS (thiab DNaZ). Qhov no xam yog sib npaug zos rau 150 lm / W. Lub payback lub sij hawm ntawm LED qij - 2-3 xyoo. Tom qab, cov seem kaum xyoo, koj cawm tau 85% ntawm cov hluav taws xob noj txhua lub hlis.
LEDs. yam ntxwv ntawm
LED, uas tus yam ntxwv yog tsis inferior analogues, muaj cov nram qab zoo:
- nyob rau hauv qhov siv thiab ua LEDs yuav siv iav, yog li illuminating teeb ntawm no hom muaj siab durability, kev co kuj thiab kev cia siab;
- LED resistant rau voltage hloov mus hloov los thiab haus xwb 0.4-0.6 A;
- Thyristor LED ua hauj lwm zoo nyob rau hauv cov huab tej yam kev mob, txawm nyob rau hauv heev tsawg kub.
Yuav pib LED, yuav tsum tau kim heev diode choj, ua tus nqi ntawm teeb pom kev zoo yav tas los yog heev overpriced. Manufacturers solved qhov teeb meem no. Schematic daim duab tau hloov thiab es tsis txhob ntawm thyristor triac dimmers tau ua ntawv thov. Cov tshwm sim yog ib tug ntaus ntawv uas muaj ob thyristors kev cob cog rua nyob rau hauv parallel, lub txee txhais tau tias. Vim li no cov innovation, qhov yuav tsum tau rau ib tug diode choj yog tsis tuaj kawm ntawv hnub no. Qhov kev txiav txim coj mus rau cheaper cov khoom thiab ho nce lub ruaj ntseg theem thiab zoo tshaj ntawm cov khoom nyob rau hauv lub hauv paus ntawm lub thyristors.
