Ordinary emitting diodes (LED teeb) tsuas yog ob lub raj taw, ib ko taw ntev thiab ib ko taw luv, uas ntev ko taw txuas nrog lub hwj chim, thiab ko taw luv yog txuas nrog lub hwj huam mov. Puas muaj LED teeb nrog plaub lub raj taw? Muaj tiag tiag li RGBLED teeb nyob rau hauv kev ua lag luam. Txij li ob ko taw txaus, vim li cas thiaj muaj plaub taw? Cov chaw tsim khoom yuav coj koj los txhais nws ntxiv. Tsis txhob saib nws plaub lub raj taw. Qhov tseeb, muaj peb lub RGBLED teeb, ib qho yog pej xeem ntawm peb lub teeb LED, thiab lwm yam peb taw yog ob lub raj ntawm txhua lub teeb LED. Lub teeb kuj muaj ib qho cathode thiab ntau anode. Rau RGBLED teeb nrog ntau anode, lub raj ntev ntawm plaub lub raj taw yog anode, uas yog, qhov zoo electrode ntawm lub hwj chim mov. Ntawm lub anode, lub rooj lus dub yog raug rau ib qho ntawm peb lub raj taw. Yog tias lub teeb ci LED no zoo li qub, koj tseem yuav pom tias lub teeb LED no yog lub teeb, thiab qhov hluav taws xob poob yuav tshwm sim ntawm lub multimeter. Cov teeb pom kev zoo tib yam LED, cov txiaj ntsig ntawm kev nthuav qhia tsis txawv. Tom qab LED teeb yog hluav taws xob, lub teeb liab yog tawm. Yog hais tias lub rooj liab yog motionless, lub rooj dub cwj mem yog raug rau lwm ob lub raj taw, thiab koj yuav pom tias yuav muaj lub teeb ntawm lwm yam xim. Ntxiv nrog rau xim liab thiab ntsuab thiab xiav, qhov no yog vim li cas nws hu ua Qhov laj thawj rau nws lub teeb RGB LED, qhov twg R sawv cev rau xim liab, los ntawm thawj tsab ntawv ntawm lus Askiv Liab (Suav lub ntsiab lus: liab); G sawv cev rau ntsuab ntawm lus Askiv Green (Suav lub ntsiab lus: ntsuab) thawj tsab ntawv; Nws yog xiav, los ntawm lus Askiv BLUE (Suav lub ntsiab lus: xiav) thawj tsab ntawv. Yog tias koj saib ntawm qhov kev poob siab thaum lub sijhawm ntsuas, koj yuav pom tias cov xim sib txawv ntawm lub teeb yuav raug tso tawm, thiab lub siab poob yuav txawv. Los ntawm daim duab saum toj no, koj tuaj yeem pom. Hauv kev xyaum, lub teeb ntawm peb xim kuj yog peb lub ntsiab xim ntawm lub teeb. Yog tias ob lub xim ntawm lub teeb LED tau teeb rau tib lub sijhawm, lub teeb ntawm lwm cov xim tuaj yeem raug tso tawm, xws li cov teeb liab thiab ntsuab LED teeb rau tib lub sijhawm. Thaum lub teeb ci LED tib lub sijhawm, lub teeb sib xyaw yuav raug tawm: lub teeb dawb. Cov tsim plaub-legged RGBLED teeb kuj muaj nws cov txiaj ntsig. Tom qab tswj hwm plaub lub raj taw no, koj tuaj yeem tswj cov teeb ci LED kom xa ntau yam xim ntawm lub teeb. Tau kawg, nws yog qhov teeb meem heev los tswj nws. Lawv. Tau kawg, koj tuaj yeem tshawb xyuas qhov zoo ntawm RGBLED lub teeb nrog txoj kev no. Yog tias koj pom tias qee cov xim (peb hom xim liab thiab xiav) pom thaum lub sijhawm kuaj pom, tom qab ntawd lub teeb ci LED uas tawm cov xim zoo li yuav tawg rau cov tib neeg, nws tsis tuaj yeem kho nws. Nws yuav tsum tau hloov. Cov chaw tsim khoom tshwj xeeb hauv kev tsim cov RGBLED teeb hlaws, thaj RGB, thiab ntsaws-hauv RGB ntau lawm. Cov phooj ywg uas xav tau tuaj yeem tiv tauj peb cov neeg ua haujlwm pabcuam hauv online.
