Nkees ntawm tus txheej txheem teeb liab hauv qab koj nas? Hloov nws tawm!

txhua yam koj xav tau yog cov hlau txuas (thiab nyiam dua yog cov cuab yeej desoldering ib yam nkaus), lub multimeter, thiab xim coj koj xav tau (thiab tejzaum nws yog tus tiv thaiv). Kuv siv tus nqi pheej yig $ 10 Ativa hom nas los ntawm Office Depot, thiab xiav coj (3.4V 8000mcd). Qhov tshwj xeeb LED no yuav tsis muaj nyob ntawm koj lub xov tooj cua shack, Kuv tshwj xeeb xaj ib pob ib ntus rov qab vim nws yog qhov hluav taws xob qis xiav LED. (thiab ci heev ib yam nkaus) Koj tuaj yeem siv xim twg ntawm LED koj xav tau, tsuav yog qhov ntsuas hluav taws xob yog 4V lossis qis dua thiab qhov ci nyob ib puag ncig 4000 - 8000 mcd. Kuv tsis ntev los no (Mar-5-08) tso UV LED nyob rau hauv HP tus nas pheej yig Kuv tau txais ib pliag rov qab rau mod. Tom qab hla tus tiv thaiv, nas tso tawm 5 qhov hluav taws xob xav tau kom tawg 3.4v coj. Nws xav tau tus tiv thaiv me me, vim nws nquag pib ua kom sov thiab yuav tsum tsis teb ob peb vib nas this. Zoo li coj txawv txawv, txawm hais tias nws ua txij li nrog lub teeb UV, nas ua haujlwm tau zoo tsuav nws tsis nyob ntawm qhov dub. Raws li txhua tus menyuam yaus uas raug dag nyob ib puag ncig nrog lub teeb pom kev dub yuav paub, cov khoom dub tsis tshua pom tshwm yog tias txhua. Lawm, lub teeb tsis pom rau lub qhov muag, thiab nas yog dig muag ntawm qhov tsaus ntuj heev.

Kauj ruam 1: Disassembly

unscrew lub vaj huam sib luag sab saum toj los ntawm lub hauv paus.

Cov ntsia hlau feem ntau muab zais hauv qab tus nas "taw", lossis cov me me dub ncoo. Thaum lawv tawm mus, tej zaum yuav muaj lub tab xauv koj yuav tsum thawb mus rau pry lub vaj huam sib luag tawm. Yog tias koj tau txais tus nas pheej yig, cov khoom siv sab hauv yuav zoo thiab loj thiab yooj yim rau ua haujlwm nrog. qhov zoo nkauj yuav muaj cov capacitors thiab resistors uas ntsuas txog 2mm x 4mm x 1mm. Cov no tsis lom zem rau tso thiab rov ua dua.

Kauj Ruam 2: Kuaj Koj Li LED

Ua ntej tearing ib yam dab tsi tawm, xyuas kom tseeb tias LED yuav ua haujlwm. Txhawm rau ua qhov no, ntsaws rau hauv nas thiab tsuas yog kov cov coj los ntawm koj li LED mus rau tib qho kev coj ua ntawm ib qho uas twb tau teeb tsa lawm. nws yog ib qho diode thiab tsuas yog ua haujlwm ib txoj kev. Qhov liab liab pom nyob rau hauv feem ntau cov nas yog 1.7V ntsuas cov diode, thiab tus tiv thaiv tau tuav lub zog qis rau qib ntawd kom LED tsis kub thiab hlawv tawm yog tias koj LED tsis pom kev, thiab koj tau teeb tsa nws kom raug, tom qab ntawd nws tsis tau txais lub zog txaus. Mine tsis tau txais lub zog txaus siv txoj hauv kev no. Txuas ib lub xov tooj cua mus rau qhov txuas ntawm LED teeb kom pom ntau npaum li cas qhov hluav taws xob tau mus hla nws -ob qho tib si ntawm qhov tsis ua haujlwm thiab thaum nas txav mus. Yog tias koj tsis tau txais lub zog txaus rau LED koj xav muab tso rau hauv, siv lub multimeter los saib seb koj yuav muaj zog npaum li cas yog tias koj hla tus tiv thaiv. Ua li no, tso lub cov khoom dub los ntawm lub ntsuas cua ntawm qhov anode ntawm tus coj (tsis zoo sab) thiab cov liab liab ntawm lwm sab ntawm tus tiv thaiv dua li LED tau txuas nrog. Kev yooj yim txaus nrog tus nas no, qhov hluav taws xob tau (Kuv ntseeg) txog 3.2V ntawm tsis ua haujlwm thiab 5V thaum txav mus. Kev ntsuas qhov kev thim rov qab, hloov chaw koj lub LED nyob rau tib qhov chaw Koj tsuas yog tso lub multimeter. As raws li koj tuaj yeem pom, ob lub LEDs muaj cov teeb pom kev zoo ib yam yog tias koj lub LED tseem tsis pom kev, pom qis dua LED. Yog tias koj lub teeb ci dhau, xav txog qee qhov me me tiv thaiv kom hloov qhov teeb tsa ib qho. nrog. Ultraviolet LEDs muaj qhov qis tshaj plaws, thiab yog li qhov siab tshaj qhov yuav tsum tau ua kom pom kev em. Blue LEDs yog qhov txuas ntxiv mus rau ntawm daim ntawv Ua raws los ntawm Ntsuab thiab qhov seem ntawm pom lub teeb pom kev zoo hauv nws qhov kev txiav txim. Red tsuas yog siv feem ntau vim tias lawv siv lub zog tsawg tshaj li lwm yam Infrared. Kuv tsis ntseeg tias lub teeb infrared tuaj yeem hnov los ntawm tus qauv nas qhov muag txawm hais tias. (qee qhov siab dua nas muaj infrared LEDs) Txhawm rau nrhiav qhov tiv thaiv tsis raug kwv yees, koj yuav xav tau qee qhov tsis zoo- kuv txhais tau tias … lej koj muaj qhov tsis kam (r), voltage (V), thiab tam sim no (Kuv, uppercase "i") Kev tiv thaiv yog ntsuas hauv ohms, qhov hluav taws xob hauv volts, thiab tam sim no hauv amps. Current = Voltage / resistance -or- I = V / rthe Circuit hauv nas feem ntau yuav khiav ntawm.02 amps. Yog li qhov tsis kam koj yuav tsum tso qhov hluav taws xob los ntawm ib nrab volt (.5V) tuaj yeem hais los ntawm qhov sib npaug: r = V / Ir =.5 /.02r = 25 ohms yog li koj yuav xav tau 25 ohm resistor hauv qhov no. Ntawm no lub laij lej yooj yim rau lub zog thiab tiv taus thiab xws li:

Kauj ruam 3: Hloov

Thaum koj muaj qhov tiv thaiv raug (yog xav tau), mus tom ntej thiab tshem tawm lub pcb (cov xim av lossis xim ntsuab tuav tag nrho cov khoom siv). Nws tau nyob hauv feem ntau los ntawm ob peb lub screws thiab tejzaum nws ob peb lub xauv ntxiv tabs.

Nws yuav tsum yooj yim yooj yim, tshwj xeeb tshaj yog nrog cov khoom loj, txhawm rau nrhiav LED thiab tus tiv thaiv uas txhuam lub zog mus rau nws. Siv cov cuab yeej desoldering kom sov thiab nqus cov laug tawm ntawm cov coj mus rau LED thiab tiv thaiv (los ntawm sab hauv qab). Khoov thiab kaw koj cov LED coj ua kom phim cov LED liab. ZOO TSHAJ PLAWS ZOO TSHAJ PLAWS ZOO TSHAJ PLAWS ZOO TSHAJ PLAWS !!! Yog tias koj xav tau kev thim rov qab rau tus tiv thaiv qhov chaw, cov tshiab coj los txiav LED yuav ua haujlwm zoo xwb. Muab koj daim tso rau hauv qhov yog thiab muab lawv tso rau hauv. Cov cuab yeej tshem tawm tuaj yeem ua haujlwm rau qhov no, tab sis siv cov hlau sib txuas ib txwm yuav ua haujlwm zoo dua.

Kauj Ruam 4: Kuaj thiab Rov Sib Dua

Mus tom ntej thiab ntsaws tus nas rau hauv thiab yog tias lub teeb tawm los, teeb lub pcb rov qab rau hauv lub hauv paus.

Tau txais txoj hlua rov qab rau hauv nws lub qhov los ntawm lub hauv paus, thiab ntsia hlau sab saum toj rov qab rau. Yog tias tus nas taw yuav tsis lo rov qab hla cov ntsia hlau zais cia, cov cim ua ntu zus, cov kua nplaum zoo, lossis txawm tias cov nplaum silicone yuav ua haujlwm los lo lawv rov rau lawv qhov chaw. Lub teeb yog ib qho tsis ua haujlwm thib 2 los ntawm daim duab kawg, thiab ua haujlwm nyob rau hauv qhov kawg.
