Cov lus qhia ib qib zuj zus rau kev tsim kho thiab siv qhov hloov pauv hloov lub teeb roj teeb siv lub teeb hluav taws xob LED tsim los ntawm Mohammed Shafir thiab Zoe Englander ua ib feem ntawm chav kawm BME 262-Tsim rau Kev Tsim Kho Ntiaj Teb ntawm Pratt Tsev Kawm Ntawv ntawm Engineering, Duke University.

Cov kab ke no yuav muab tus nqi qis thiab hloov pauv mus ntev rau qhov nyuaj kom tau txais cov teeb pom kev phais hauv kev tsim kho ntiaj teb. Cov lus qhia no piav qhia yuav siv lub tshuab hloov roj teeb li cas nrog cov khoom siv thiab cov cuab yeej suav nrog hauv cov khoom siv. Cov cuab yeej siv hauv ntiaj teb kev tsim kho uas xav tau lub teeb pom kev zoo los ua lawv txoj haujlwm yog qhov tseem ceeb hauv kev muab kev kho mob. Txawm li cas los xij, teeb meem loj nrog kev siv cov cuab yeej no hauv kev tsim kho lub ntiaj teb yog tias thaum lub teeb pom kev tawg los yog hlawv tawm, hloov qhov muag teev yog kim heev lossis nyuaj rau tau txais. Yog li, ntau yam khoom siv uas ua haujlwm tau zoo ib yam yog tsis tau siv vim tias lawv tsis muaj qhov muag teev ua haujlwm. Ib qho cuab yeej kho mob tseem ceeb uas raug teeb meem los ntawm qhov teeb meem no yog teeb teeb phais uas siv hauv chav kho mob. Cov teeb no yog qhov tseem ceeb siv rau tus kws phais kom pom qhov chaw txaus siab thaum phais. Qhov tsis muaj cov teeb no cuam tshuam loj heev rau cov kws phais neeg lub peev xwm los txiav txim siab paub thiab tseem txwv kev ua haujlwm ntawm kev phais mus rau ib ntus nyob rau ib hnub thaum muaj lub teeb txaus los ua kom pom chav. Peb tau kho qhov teeb meem no nrog kev hloov lub teeb uas yuav tso cai rau tus neeg siv hloov lub teeb pom kev zoo ib txwm siv lub teeb phais nrog lub teeb pom kev tshiab tsim los ntawm Lub Teeb Emitting Diode (LED) qhov muag teev. Cov qij LED muaj txiaj ntsig ntau dua li cov tungsten lossis cov qij halogen, siv hluav taws xob tsawg dua, nruj dua (vim tsis muaj qhov txav chaw) thiab tseem muaj lub neej nyob ntev dua. Yog li ntawd, lub teeb pom kev zoo ntawm LED yuav muaj lub neej ntev dua, tsis kim kom khiav, thiab yuav tsis tawg yooj yim li. LED teeb pom kev zoo tsuas yog yuav tsum tau teeb tsa ib zaug, thiab yuav tsis hloov pauv ntau xyoo. Ib qho ntxiv, cov kab ke no sib xws nrog ntau hom teeb sib txawv, nrog rau ntau qhov sib txawv ntawm qhov muag teeb. Cov kab ke no siv lub hauv paus tseem ceeb ntawm lub teeb ci, yog li lub Circuit Court tuaj yeem ua kom haum nrog yuav luag txhua qhov loj thiab cov duab ntawm lub teeb. Lub kaw lus yuav ua haujlwm rau txhua lub teeb uas siv ntawm 7 thiab 24 volts DC.

Luam tawm cov txheej txheem PCB muab rau ntawm no kom pom tseeb. Tau txais PCB pawg thawj coj, txiav nws kom raug rau qhov loj me, thiab tso lub pob tshab ntawm pawg thawj coj saib thiab lub teeb nyob hauv chav tsaus ntuj. Muab ib daim iav tso rau ntawm pob tshab kom ua kom cov qauv tsim thiab pom kev zoo ib yam. Ua kom ntseeg tau tias qhov kev tsom mus rau qhov yog, thiab daim ntawv tiv thaiv yog tev tawm. Tom qab li 7 feeb nyob rau hauv qhov pom kev, tso lub rooj tsavxwm hauv da dej ntawm cov dej tsim tawm. Nco ntsoov hnav hnab looj tes los tiv thaiv koj txhais tes, thiab ceev faj kom tsis txhob txau cov kua hauv koj cov khaub ncaws. Cov dej tsim tawm yuav tsum yog 1 feem tsim tawm mus rau 10 ntu dej.

Tom ntej no, tso PCB rau hauv lub lauj kaub ntawm cov tshuaj tov. Ua kom lub lauj kaub ua kom cov txheej txheem ua kom nrawm dua. Nws kuj tseem pab kom sov cov tshuaj me ntsis. Khaws PCB hauv kev daws kom txog thaum tag nrho cov tooj liab raug tshem tawm tshwj tsis yog tias qhov tsim qauv tsim hluav taws xob luam tawm ntawm lub rooj tsavxwm. Kev daws teeb meem yuav ua rau koj cov khaub ncaws tsis huv, yog li ceev faj heev kom tsis txhob txaws rau ntawm koj tus kheej. Yaug daim ntawv luam tawm kom huv kom tshem tag nrho cov kua. Cov txheej txheem luam tawm tau tsim los kom ob lub vojvoog thiab ob daim LED tuaj yeem haum rau hauv ib lub rooj tsav xwm PCB. Cais plaub daim no siv lub saw. Txiav tawm ib lub rooj tsav xwm ntau dhau los ua kom lub Circuit Court me me li sai tau. Thaum kawg, laum lub qhov uas cov khoom sib txuas yuav txuas nrog siv lub laum me me. Cov chaw uas koj xav tau los laum tau pom ua cov voj voog me me ntawm PCB txheej txheem. Peb siv ExpressPCB los tsim lub rooj tsavxwm no. Txij li qhov kev siv hluav taws xob no siv cov khoom siv saum npoo av, cov txheej txheem tsim cov laug yuav tsum tau ua tiav rau txhua tus neeg.

Thawj kauj ruam tsim nyog hauv kev ua haujlwm ntawm cov txheej txheem no yog tshem cov iav los ntawm lub teeb tawg kom nthuav tawm cov neeg sib cuag uas coj mus rau qhov tawg tawg.

Tshem lub teeb tawg los ntawm nws lub qhov (socket). Muab lub qhov tawg tawg tso rau hauv lub hnab yas (muab) thiab tuav lub teeb los ntawm sab nraud ntawm lub hauv paus. Ceev faj tsis txhob txiav koj tus kheej nrog iav lossis ntaus koj cov ntiv tes nrog rauj. Tawm sab saum toj ntawm lub teeb phais phais tawg nrog me me rauj. Ceev faj tsis txhob ntaus lub teeb nrog lub zog ntau dhau. Lub hom phiaj yog tshem tawm cov iav thiab nthuav tawm cov neeg sib txuas uas thaum xub thawj txuas nrog cov kab tawg tawg mus rau qhov seem ntawm lub teeb.

Cov kauj ruam tom ntej yog txhawm rau txuas lub Circuit Court nrog LED rau lub teeb. Muab cov neeg sib txuas rau cov xov hlau uas tawm ntawm lub Circuit Court.

Ua kom sov cov hlau txuas los ntawm kev ntsaws rau hauv. Qhov no yuav ua rau cov hlau yaj. Ua tib zoo xa cov kua nplaum yaj mus rau cov neeg sib txuas thaum tuav cov xov hlau los ntawm kab hluav taws xob hauv cov laug yaj. Luv luv tso cai rau kev sib txuas kom txias thiab ua kom ntseeg tau tias qhov kev sib txuas muaj zog txaus. Koj yuav xav tau tuav cov khoom sib xyaw ua ke siv tus tweezers thaum koj ua tiav cov txheej txheem no. ** Ceev faj: Soldering Hlau kub heev, tsis txhob hlawv koj tus kheej!
