Cov tsav tsheb LED yog ib qho khoom siv hluav taws xob uas tswj hwm lub zog rau LED lossis ib txoj hlua ntawm LED. Nws yog qhov tseem ceeb rau daim LED Circuit Court thiab kev ua haujlwm tsis muaj ib qho yuav ua rau lub kaw lus tsis ua haujlwm.
Hauv tshuab hluav taws xob, tus tsav tsheb LED yog hluav taws xob siv hluav taws xob los siv hluav taws xob tso hluav taws xob (LED). Tus tsav tsheb LED yuav tsum muab qhov tam sim no txaus rau lub teeb ci ntawm LED thaum yuav tsum muaj qhov ci, tab sis yuav tsum txwv qhov tam sim no kom tsis txhob ua rau lub LED tawg. Lub voltage poob hla ib qho LED yog kwv yees tsis tu ncua dhau ntawm ntau qhov kev ua haujlwm tam sim no; yog li ntawd, nce me me ntawm kev thov voltage zoo heev nce qhov tam sim no. Lub voj voog yooj yim heev yog siv rau qhov ntsuas hluav taws xob muaj zog LED. Ntau cov nyom, qhov hluav taws xob tam sim no yuav tsum muaj thaum tsav hluav taws xob siab LED rau lub teeb pom kev zoo kom ua tiav cov kev cai tam sim no.
Hauv qab no yog yuav ua li cas xav txog ua ntej xaiv tsav tsheb LED
1. Dab tsi ntawm LEDs siv thiab ntau npaum li cas?
2. Tshawb xyuas qhov hluav taws xob rau pem hauv ntej, kev pom zoo tsav tsheb tam sim no, thiab lwm yam.
3. Kuv puas xav tau tus tsav tsheb LED hluav taws xob tas mus li lossis ib qhov txuas hluav taws xob LED tsav tas mus li?
4. Peb mus dhau qhov tam sim no thiab qhov hluav taws xob tas li ntawm no.
5. Lub zog yuav siv qhov twg? (DC, AC, roj teeb, thiab lwm yam)
6. Khiav los ntawm AC? Saib seb AC tsav tsheb yuav pab tau koj li cas!
7. Dab tsi yog qhov chaw txwv?
8. Ua haujlwm hauv thaj chaw nruj? Tsis muaj ntau qhov voltage los ua haujlwm nrog?
9. Cov hom phiaj tseem ceeb ntawm daim ntawv thov yog dab tsi?
10. Qhov loj me, nqi, ua haujlwm, ua haujlwm, thiab lwm yam
11. Puas muaj qhov tshwj xeeb tshwj xeeb? Dimming, pulsing, microprocessor tswj, thiab lwm yam.
