Puas yog coj lub teeb tsav tsheb fais fab mov thiab hloov fais fab mov tib yam?
Puas yog coj lub teeb tsav tsheb fais fab mov thiab hloov fais fab mov tib yam? Rau qhov input voltage ntawm AC220V LED teeb tsav tsheb fais fab mov, nws cov tswv yim AC220V voltage ua ntej kho, lim rau hauv DC high voltage, thiab tom qab ntawd los ntawm tus neeg tsav tsheb tshwj xeeb tam sim no IC (xws li HV9910) yuav yog DC high voltage mus rau qhov tso zis tam sim no. . Peb paub tias LED teeb hlaws yog cov khoom tsis-linear, nyob rau hauv lub teeb hlaws tom qab kev coj ua, lub teeb hlaws ntawm ob sab ntawm lub zog rau pem hauv ntej yog tias muaj qhov hloov pauv me me, qhov ntws ntawm cov hlaws hlaws ntawm lub hauv ntej tam sim no. yuav yog ib qho kev hloov loj, yog li LED teeb hlaws dai feem ntau yog siv nyob rau hauv ib txwm-tam sim no tsav, yog li tsis hais seb tus tsav tsheb fais fab yuav tsav lub teeb hlaws los yog kaum ob lub teeb, qhov tam sim no ntws los ntawm lub teeb hlaws yog qhov tsis tu ncua. .
Rau cov input voltage ntawm AC220V switching fais fab mov, nws input theem Circuit Court kuj yog thawj AC220V rectification, filtering rau DC high voltage, tab sis tom qab siv tshwj xeeb voltage regulator IC yuav DC high voltage mus rau qhov yuav tsum tau ruaj khov voltage. Raws li qhov tso zis hluav taws xob ntawm qhov hloov hluav taws xob hloov pauv tsis tu ncua, cov zis tam sim no sib txawv nrog cov khoom thauj, yog li cov khoom siv hluav taws xob no tsis tuaj yeem txuas ncaj qha mus rau LED teeb hlaws, txwv tsis pub cov hlaws hlaws yuav raug puas tsuaj vim muaj ntau dhau tam sim no.
LED tsav tsheb kuj tseem yog lub zog hloov hluav taws xob
1, tsim raws li ib qho hluav taws xob transformer hom voltage tso zis nyob rau hauv daim ntawv ntawm 3.2V, 6.4V.9.6V, 12.8V ..... , tab sis feem ntau tsis tshaj 25.6V, vim hais tias ntau tshaj li qhov no tus naj npawb ntawm thaum lub LED yog qhib, qhov muaj peev xwm ntawm kev hlawv tawm qhov kawg conductive LED yuav tshwm sim tam sim vim qhov tsis zoo rau ib qho ntawm cov khoom. Thiab qhov hluav taws xob no tsis tas li, tab sis Nrog kev hloov pauv ntawm kev thauj khoom thiab kev hloov pauv, txhawm rau ua tiav lub hom phiaj ntawm qhov tsis tu ncua tam sim no.
2, nws cov zis tam sim no tsis tu ncua, qhov zoo tshaj plaws Circuit Court tsis muaj teeb meem li cas cov yam ntxwv nkhaus ntawm LED hloov, tam sim no ntawm lub zog tsav hluav taws xob tseem tsis hloov. Tab sis tsuas yog txwv rau cov ntsiab lus precision, lossis yuav muaj qhov hloov pauv me me, thiab qhov kev hloov pauv no tseem yog qhov tseem ceeb los txiav txim siab seb tus tsav tsheb puas zoo heev, LED ntawm thiab qhov hluav taws xob muaj nuj nqi yog qhov tsis yog-linear "peb" kev sib raug zoo, yog li tswj xyuas tam sim no tsis tu ncua. Kev sib raug zoo, yog li nws tseem ceeb heev kom tswj tau qhov tam sim no tsis tu ncua.
3, nws pib yog mos pib. Vim yog qhov sib xws ntawm LED yog qhov tsis zoo, thiab nyob rau hauv lub sijhawm ua haujlwm ntawm kev sib tshuam PN junction instantaneous hloov, yog li tus neeg tsav tsheb LED feem ntau tsim rau muag muag, kom tsis txhob muaj qhov tsis xws luag.
Yog li LED tsav tsheb yog ib qho kev ua haujlwm tas mus li tam sim no, lub tshuab hluav taws xob hloov hluav taws xob tau kho, ob qhov sib txawv.
