Yog tias LEDs siv nyob rau hauv ib qho qauv tsim rau qhov ntsuas, backlight lossis teeb pom kev zoo, lawv yuav tsum raug xaiv kom raug. Cov twj paj nruag no muaj ntau txoj hauv kev thiab muaj nyob hauv ntau yam kev sib txuas.
Cov Lus Qhia

Xaiv yam dab tsi yoj lub LED yuav tsum muaj. Cov xim liab sib xws rau nthwv dej ntawm kwv yees li 635 nanometers, daj - 570, lub teeb ntsuab - 550, kab tho - 520, xiav - 500, violet - 430. Dawb LED muaj lub dav hluav taws xob thiab suav nrog hluav taws xob nrog ntau lub yoj yoj. Qhov xaiv cov xim raws nrog koj nyiam los yog nyiam ntawm cov neeg siv khoom. Nco ntsoov tias tsuas yog liab tuaj yeem siv los ua lub cim qhia txog kev phom sij, thiab xiav thiab violet tsis haum rau qhov pom nplai qhov ntsuas thiab ntsuas, thaum nyeem lawv, koj yuav tsum ua kom lub ntsej muag nyom Cov xim ntawm cov cuab yeej siv hluav taws xob teeb pom kev zoo yuav tsum sib haum nrog cov kev cai hauv cov ntaub ntawv tswj kev cai.

Tau txiav txim siab ntawm lub nthwv dej, txuas mus rau kev xaiv ntawm cov duab ntsuas thiab ntsuas qhov teeb meem ntawm lub diode. Siv puag ncig rau lub teeb pom kev thiab qhov taw qhia. Rau lub hom phiaj thib ob, koj kuj tuaj yeem siv cov duab sib dhos LEDs, tab sis nws nyuaj rau qhov ua qhov hauv qhov xwm txheej rau lawv - koj yuav tsis tuaj yeem tho lawv. Yog li ntawd, cov diodes zoo li hauv cov nplai yog tsim nyog dua. Rau kev taw qhia teeb pom kev zoo, siv cov khoom siv nrog cov lo ntsiab muag, rau qhov sib txawv ntawm lub teeb pom kev zoo - hauv cov vaj tsev matte. Rau cov hlua qhov twg nws yog ib qho tseem ceeb uas lub diode pom tau pom los ntawm ib lub kaum ntse ntse, siv ntaub nplaum tsis zoo. Yog tias kev teeb tsa ntawm lub LED hluav taws xob tsis tshua muaj zog yuav tsum tau nqa tawm ntawm lub rooj tsavxwm uas siv cov khoom siv thev naus laus zis, nws yog qhov zoo dua los siv SMD diode.

Tom qab ntawd txiav txim siab ua haujlwm tam sim no ntawm lub diode. Nco ntsoov tias kev siv fais fab yog sib npaug nrog cov khoom ntawm qhov tam sim no thiab qhov ntsuas hluav taws xob. Cov hluav taws xob tso hluav taws xob hla lub teeb liab dawb yog los ntawm 3 mus rau 4 V. Lub zog hluav taws xob yog sib npaug ntawm cov khoom lag luam ntawm cov khoom noj thiab qhov ua kom zoo. Rau qhov taw qhia LEDs, nws yog kwv yees li 20 feem pua, rau lub teeb pom kev zoo ntawm LED, nws tuaj yeem ncav cuag 50. Thov nco ntsoov tias qee qhov xwm txheej, kev siv ntawm ob peb lub zog hluav taws xob LED muaj kev lag luam ntau dua li siv ib qho ib qho sib piv hauv qhov ci ci.

Muaj qee kis, kev siv cov hom tshwj xeeb ntawm LED pom kev ncaj ncees. Yog li, ob- thiab peb-kua siv diodes muaj peev xwm hloov xim sai raws lub teeb liab los ntawm kev tswj kav. LED nrog cov tswj kev tsim hluav taws xob pib pib ntsais lossis hloov xim (sib luag lossis maj nrawm, nyob ntawm seb hom) thaum lub zog siv. Qhov no tso cai rau ntau qhov ua tau zoo hloov kom tau yam tsis muaj kev cuam tshuam cov qauv hauv cov diodes tau raug ntsia.

Muaj xaiv tag nrho cov kev ntsuas, xaiv cov LED raws li phau ntawv qhia lossis phau ntawv teev npe, lossis hauv kev sab laj nrog tus muag. Yog tias lub vev xaib ntawm kev tsim kev lag luam yog nruab nrog txoj haujlwm ua haujlwm, nkag mus rau qhov xav tau ntawm cov diode nyob hauv daim ntawv ntawm nws, tom qab ntawd tsuas yog cov npe uas haum koj yuav cia li lim.
Kauj Ruam 6
Thaum nriav diodes, tig lawv nrog qhov tseeb polarity. Kev ua haujlwm rau lawv tsuas yog ntawm lub sijhawm tam sim no tsis tau dhau ntawm qhov ntsuas rated.
