Qee cov phooj ywg nug cov txheej txheem thiab kev kho mob ntawm Led teeb liab teeb ntsais ntsais vim li cas cov neeg vim li cas lub teeb liab teeb tsis pom kev. Dab tsi yog mus? Qhov tseeb, muaj peb qho kev ua tsis tiav thiab cov kev daws teeb meem rau cov teeb liab teeb.
Peb cov kev ua tsis tiav ntawm Led teeb liab teeb thiab cov kev daws teeb meem:
Ib qho txhaum ua txhaum yog Rectifier tsis ua hauj lwm. Mus rau lub nroog lub nroog thiab yuav ib qho thiab hloov nws. Tag nrho LED yog tsis tshua muaj kev puas ntsoog.
Ob. LED teeb liab teeb ntsais muag cov laj thawj:
1. Lub teeb hlaws dai thiab LED Drive zog tsis sib xws, ib txwm muaj 1W teeb liab, yog tias lub teeb app tam sim no thiab: 3.0-3.4V voltage tsis muaj zog txaus, yuav ua rau lub teeb ci txaus Qhov tshwm sim, yog tias tam sim no loj heev, teeb hlaws yuav tsis tuaj yeem tiv thaiv tus hloov. Thaum muaj mob hnyav, kub lossis luam xov tooj liab hauv cov hlaws dai tuaj yeem hlawv tawm, ua rau cov hlaws dai kom tsis ua haujlwm.
2. Lub zog tsav tsheb yuav raug puas ntsoog, ntev npaum li koj hloov nws nrog lwm lub zog tsav lub zog zoo, nws yuav tsis ntsais.
3. Yog tias tus tsav tsheb muaj txoj haujlwm ntawm kev tiv thaiv kev ua haujlwm dhau los, tiv thaiv tshav kub tsis tau ntawm tus tsav tsheb yuav ntsais muag thaum nws pib ua haujlwm. Piv txwv li, tus 20 wition nthuav tawm teeb tsa vaj tsev tau siv los sib dhos 30W teeb tsis ua txoj haujlwm zoo ntawm kev txias.
4. Yog tias lub teeb sab nraud kuj tseem muaj qhov tshwm sim strawboscopic, nws txhais tau tias cov teeb yog dej nyab. Raws li qhov tshwm sim, yog tias nws blinks, nws tsis muaj lub teeb. Lub beacon thiab tus tsav tsheb tawg. Yog tias tus neeg tsav tsheb ua haujlwm tau zoo ntawm kev ywg dej, lub teeb hlaws tawg yog tawg thiab lub teeb ci tuaj yeem hloov tau.
Peb. Ua ntawm LED Teeb Liab Teeb Kev:
1. Nyob rau hauv off-life-zog coj teeb pom kev zoo, cov hluav taws xob sib txawv yog cov flyback flyback todology. Lub teeb ntsuab ntsuab, muaj 8W tawm-Line LED Tsav Tsheb, ntsib lub zog hnub qub-lub xeev teeb pom kev zoo. Hauv cov ntaub ntawv tsim, vim hais tias cov Sinusoidal Square yoj lub zog hloov pauv ntawm lub zog uas muaj kev sib cav sib ceg tsis muaj zog rau thawj lub zog ntawm tus kheej, lub zog kev siv tus kheej sib txuas tau ua kom zoo thiab ua rau lub teeb taub hau. Txhawm rau zam qhov teeb meem no, nws yog ib qho tsim nyog los ua kev tawm thawj qhov tawm hauv txhua ib nrab hlis. Yog li ntawd, nws yog ib qho tsim nyog los xaiv qhov kev muaj peev xwm capacitance thiab kev tiv thaiv muaj nuj nqis ntawm lub teeb liab LED teeb tsa uas suav nrog Circuital.
2. Feem ntau tib neeg lub qhov muag tuaj yeem pom cov flicker ntawm lub teeb ntawm ib zaus ntawm 70 hz, tab sis saum toj no nws ua tsis tau. Yog li ntawd, hauv teeb pom kev teeb pom kev zoo, yog tias cov mem tes teeb pom kev muaj tsawg zaus nrog ib zaus hauv qab 70 hz, tib neeg lub qhov muag yuav hnov zoo nkauj. Ntawm chav kawm, muaj ntau ntau yam uas tuaj yeem ua rau LED teeb ntsais muag rau hauv ib daim ntawv thov tshwj xeeb.
3. EMI cov ntxaij lim dej txawm tias nyob rau hauv cov ntawv siv LED tsav uas muab kev txhawb nqa lub zog zoo ntawm peb-terminal bi-directional scriples. Cov kev ua txhaum tam sim no los ntawm cov kauj ruam ntawm tritherrchectional scripection Scripe lub ntuj resonance ntawm inductors thiab capacitors hauv lub lim EMI.
Yog tias qhov kev resonance yam ua rau cov tswv yim tam sim no kom muaj qis dua li tuav tam sim no ntawm peb-terminal bi-directional scracks yuav muab tua. Tom qab ncua sijhawm qeeb, peb-terminal Benirectional Scr Hloov lub zog feem ntau yuav tig rov los ua kom zoo ib yam li qub. Cov txheej txheem ntawm cov xwm txheej no yuav rov qab ua ntau zaus nyob rau ib nrab hlis ntawm lub zog tawm hluav taws xob Waveform, uas tshwm sim hauv pom coj los fliRaws.
