Lub hauv paus ntsiab lus ua haujlwm ntawm LED teeb yog dab tsi?
LED (Lub Teeb Emitting Diode), lub teeb -emitting diode, yog ib qho khoom siv hluav taws xob- lub xeev semiconductor uas tuaj yeem hloov hluav taws xob hluav taws xob mus rau qhov pom pom, uas yog, lub teeb -emitting diode, uas tuaj yeem hloov hluav taws xob ncaj qha rau hauv lub teeb. Lub plawv ntawm LED yog semiconductor nti, ib kawg ntawm nti yog txuas mus rau lub bracket, ib kawg yog qhov tsis zoo electrode, thiab lwm kawg yog txuas nrog lub zoo electrode ntawm lub hwj chim mov, kom tag nrho cov nti yog encapsulated. los ntawm epoxy resin. Lub semiconductor wafer muaj ob feem, ib feem yog P-hom semiconductor, nyob rau hauv uas lub qhov dominate, thiab lwm kawg yog N-hom semiconductor, qhov twg electrons feem ntau. Thaum ob lub semiconductors txuas nrog, P-N kev sib tshuam yog tsim los ntawm lawv. Thaum cov tam sim no ua rau lub wafer los ntawm cov hlau, cov electrons yuav raug thawb mus rau thaj tsam P, qhov twg cov electrons thiab qhov recombine, thiab ces emit zog nyob rau hauv daim ntawv ntawm photons, uas yog lub hauv paus ntsiab lus ntawm LED teeb. Lub wavelength ntawm lub teeb, uas kuj yog xim ntawm lub teeb, yog txiav txim los ntawm cov khoom uas tsim P-N hlws ris.
Ib lub teeb ci LED tsuas tuaj yeem ua haujlwm ntawm qhov tsis tshua muaj hluav taws xob (txog 3V) thiab qis tam sim no (kwv yees li ob peb milliamps), thiab lub teeb tawm tsis muaj zog heev. Ntau LED teeb hlaws yuav tsum tau txuas nrog hauv series los yog nyob rau hauv parallel; Nyob rau tib lub sijhawm, ib leeg LED teeb hlaws yog unidirectionally conductive. Txhawm rau kom ua tiav kev siv tag nrho ntawm qhov zoo thiab qhov tsis zoo ib nrab- lub voj voog tam sim no ntawm qhov hloov pauv tam sim no, ib qho kev sib txuas ua ke yuav tsum tau hloov pauv 220V fais fab mov hloov mus rau qhov hluav taws xob thiab lub zog tam sim no. Qhov ncaj qha tam sim no uas phim cov LED sau tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm LED teeb hlaws sau, kom nws tuaj yeem tawm lub teeb ib txwm.
Shenzhen Benwei Teeb pom kev zoo Technology Co., Ltd yog cov chaw tsim khoom lag luam hauv kev tsim cov khoom siv teeb pom kev zoo, Peb cov khoom tseem ceeb T8 T5 LED Tube, LED Loj Hlob Teeb, Nqaij qaib LED Teeb, Tri- pov thawj LED Teeb, LED Dej nyab lub teeb, LED vaj huam sib luag , LED Stadium Teeb, LED High Bay, LED Sawb teeb, Yog tias koj xav yuav ib lub siab -cov khoom siv teeb pom kev zoo LED lossis muaj kev nkag siab ntau ntxiv hauv - qhov tob tob ntawm daim ntawv thov ntawm LED teeb, thov hu rau xa peb nug.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm tseem ceeb ntawm tag nrho -xim LED yog: kev hloov ntawm xya xim yog pom tau los ntawm peb lub ntsiab xim ntawm liab, ntsuab thiab xiav, thiab cov mem tes dav modulation ntawm cov zis waveform yog siv, uas yog, Lub voj voog lub luag haujlwm ntawm lub teeb ci LED tau hloov kho, thiab qhov ntsuas nrawm nrawm heev. Nws siv qhov pom kev inertia ntawm tib neeg lub qhov muag kom ua tiav cov nyhuv gradient.
