Dab tsi yuav tsum tau them nyiaj mloog rau hauv kev tsim ntawm LED vaj huam sib luag lub teeb fais fab mov?
LED vaj huam sib luag teeb yog lub siab -kawg sab hauv tsev teeb pom kev zoo. Nws sab nrauv yog ua los ntawm aluminium alloy los ntawm anodizing. Lub teeb ci yog LED. kev xav zoo nkauj. Yog li dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum tau ua tib zoo saib rau hauv kev tsim ntawm LED vaj huam sib luag lub teeb hluav taws xob, cov editor hauv qab no yuav qhia koj txog peb lub ntsiab lus tseem ceeb ntawm LED vaj huam sib luag teeb lub zog tsim khoom.
1. Vim li cas LED vaj huam sib luag lub teeb hluav taws xob yuav tsum muaj qhov tam sim no tsis tu ncua?
Cov yam ntxwv ntawm LED semiconductor nyob rau hauv lub teeb vaj huam sib luag LED txiav txim siab tias nws cuam tshuam rau ib puag ncig. Piv txwv li, thaum kub nce, qhov tam sim no ntawm LED yuav nce; Thaum qhov voltage nce, tam sim no ntawm LED kuj yuav nce. Tshaj qhov ntsuas tam sim no rau lub sijhawm ntev yuav ua rau lub neej ua haujlwm luv ntawm LED. LED tsis tu ncua tam sim no yog los xyuas kom meej tias nws cov kev khiav hauj lwm tam sim no tseem tsis hloov thaum ib puag ncig yam xws li kub thiab voltage hloov.
2. Yuav ua li cas lub LED vaj huam sib luag teeb lub hwj huam mov haum lub teeb board?
Some customers first design the LED panel light board, and then look for the power supply, and find that it is difficult to have a suitable power supply, either the current is too large and the voltage is too small (such as I>350mA, V<40v); or="" the="" current="" is="" too="" small,="" the="" voltage="" is="" too="" high="" (="" such="" as=""><40ma, v="">180V), qhov tshwm sim yog qhov tsim hluav taws xob loj, kev ua haujlwm qis, lossis tsis txaus cov khoom siv hluav taws xob. Qhov tseeb, yog tias koj xaiv qhov zoo tshaj plaws series- txoj kev sib txuas sib txuas, qhov hluav taws xob thiab qhov tam sim no siv rau txhua qhov LED yog tib yam, thiab cov txiaj ntsig ntawm cov khoom siv hluav taws xob tuaj yeem ua tau zoo tshaj plaws. Txoj hauv kev zoo tshaj plaws yog kev sib txuas lus nrog cov chaw tsim khoom siv hluav taws xob ua ntej thiab kho nws.
3. Dab tsi yog qhov tsim nyog ua haujlwm tam sim no ntawm LED vaj huam sib luag lub teeb fais fab?
Qhov ntsuas ua haujlwm tam sim no ntawm LED vaj huam sib luag teeb yog feem ntau 20 mA. Qee lub tsev tsim khoom siv thaum pib thiab tsim 20 mA. Qhov tseeb, kev ua haujlwm kub yog qhov hnyav heev nyob rau hauv qhov tam sim no. Tom qab ntau qhov kev sib piv, nws yog tsim los ua 17-19 mA. Ib qho zoo tagnrho, thiab kev pom zoo tsim yog 18 mA.
Cov saum toj no yog tus yuam sij rau lub hwj huam mov tsim ntawm LED vaj huam sib luag teeb. Yog tias koj xav paub ntau ntxiv txog LED vaj huam sib luag teeb, thov hu rau peb lub tuam txhab kev sab laj dawb.
