Vim li cas LED txoj kev teeb flickering?
Tom qab lub teeb ci LED tau qhib, nws yuav tsis teeb tom qab flash. Qhov kev ua txhaum ntau yog kev puas tsuaj ntawm lub teeb hlaws lossis kev puas tsuaj ntawm lub hwj chim lim capacitor. Lub teeb hlaws ntawm LED teeb feem ntau yog tsim los ntawm ntau lub teeb hlaws hauv series. Yog tias ib qho ntawm lub teeb hlaws raug puas lawm thiab nyob rau hauv lub xeev qhib, txoj hlua ntawm cov hlaws teeb yuav tsis teeb. Yog tias lub teeb ci LED yog tsim los ntawm ntau txoj hlua ntawm lub teeb hlaws txuas nrog hauv cov koob, tom qab ntawd kev puas tsuaj rau ib lub teeb hlaws yuav tsuas ua rau qee lub teeb hlaws ntawm LED teeb tawm.
Yog tias lub teeb ci LED tsis teeb, koj tuaj yeem disassemble rooj plaub kom pom tias muaj kev puas tsuaj rau lub teeb hlaws. Feem ntau, cov khoom siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob muaj qhov chaw dub ntawm lub teeb hlaws. Nrhiav hom teeb pom kev zoo no thiab hloov nws nrog lub teeb hlaws ntawm tib lub ntsiab lus. Yog tias koj tsis tuaj yeem pom cov teeb pom kev tsis zoo ntawm lub ntsej muag, koj tuaj yeem siv lub ntsuas ntsuas diode iav kom pom cov hlaws tsis zoo.
Yog tias lub teeb ci LED muaj ntau txoj hlua ntawm cov hlaws dai txuas nrog hauv cov koob, tom qab tig lub teeb, nws yuav flicker thiab tsis teeb. Nyob rau hauv cov ntaub ntawv no, muaj peev xwm tsis ua hauj lwm ntawm qhov tam sim no tsav Circuit Court yog feem ntau siab dua. Thaum lub sij hawm tu, koj tuaj yeem disassemble tus tsav tsheb tam sim no ntawm LED teeb, thiab tsom mus rau kev kuaj xyuas ob lub electrolytic capacitors hauv tus tsav tsheb. Lub capacitor C2 hauv daim duab saum toj no yog lub hwj chim lim capacitor. Yog hais tias qhov hluav taws xob tiv taus ntawm lub capacitor tsis siab txaus, nws yooj yim rau kev tawg thiab kev puas tsuaj, ua rau tus neeg tsav tsheb tsis muaj qhov hluav taws xob tso tawm, kom lub teeb LED tsis tuaj yeem teeb. Capacitor C1 txuas nrog rau qhov sib npaug nrog cov zis kawg ntawm tus tsav tsheb (piv txwv li, ob qhov kawg ntawm LED teeb hlaws). Yog tias lub capacitor tawg, LED teeb yuav tsis teeb. Tsis tas li ntawd, qee tus tsav tsheb LED muaj lub fuse ntawm qhov kawg ntawm cov khoom siv. Yog tias lub fuse tawg, LED teeb yuav tsis teeb.
Benwei Teeb pom kev zoo yog LED Tube, LED dej nyab teeb, LED Vaj Huam Sib Luag Teeb, LED High Bay, LED chaw tsim tshuaj paus nrog 12 xyoo kev paub.
