Compact Fluorescent Light Bulbs (CFLs) tau nrov dua raws li txoj hauv kev los cawm qee lub zog. Thaum kawg, lawv hlawv tawm. Qee qhov zoo li hlawv tawm nrawm nrawm:-(Txawm hais tias tsis tau hlawv tawm, CFL qhov muag tau dhau los ua qhov pheej yig heev, tshwj xeeb tshaj yog tias koj nyob hauv ib cheeb tsam uas lawv tau txais nyiaj pab los ntawm koj lub chaw siv hluav taws xob hauv zej zog. Koj puas muaj cov nyiam nyiam siv cov khoom siv hluav taws xob sab hauv CFL Lawv ua haujlwm li cas, txawm li cas los xij? Thiab thaum lawv hlawv tawm, vim li cas lawv thiaj hlawv tag? Cia wb sib nrug thiab pom! t muaj kuv tus kws lij choj tshuaj xyuas Gnu Daim Ntawv Tso Cai Pub Dawb)

Kauj Ruam 1: Coj Nws Sib nrug 1: Txiav Pry-slot

Feem ntau ntawm CFLs kuv tau pom muaj qhov sib khi uas lawv tuaj yeem raug sib cais yam tsis muaj teeb meem ntau dhau. Qee lub sij hawm cov hlua txuas los yog "txuas" ua ke, lwm lub sijhawm nws tsuas yog qhov uas ob daim tau "nias haum" ua ke. txhais tes, yog tias tsuas yog vim ib qho ntawm ib nrab tsuas muaj cov iav raj kom tuav tau. Qee lub sij hawm qhov sib koom ua ke yog xoob thiab/lossis loj txaus kom haum rau hauv lub taub hau ntswj ntsia hlau, tab sis nws yog qhov yooj yim tshaj plaws (piv txwv tias koj tsis xav rov siv lub teeb roj teeb rov qab) los txiav qhov ntiav ntiav ntawm txoj hlua nrog hacksaw. Tsuas yog tuav lub tsev kom ruaj ntseg (hauv lub vise me me zoo li daim duab, lossis tsis yog), thiab pom lub qhov tsuas yog nyuam qhuav dhau los ntawm lub casing - txog 4 hli. Ib cag los ntawm cov ntug ntse, lub teeb fluorescent muaj cov phosphors ntawm qhov tsis paub thiab muaj peev xwm ua rau muaj pes tsawg leeg, thiab cov tshuaj mercury me me uas koj tsis xav tso tawm hauv koj lub tsev lossis chaw ua haujlwm.

Kauj Ruam 2: Muab Nws Sib nrug 2: Pry Nws Sib nrug

Tam sim no koj muaj lub qhov, koj yuav tsum muaj peev xwm ntxig lub hau ntswj ntsia hlau. Nrog kev sib tw me ntsis, qhov seem ntawm qhov nqes yuav sib cais (txawm tias glued lossis welded.) (Tuav ntawm lub raj iav, lossis nws yuav poob thiab tsoo qee yam thiab tawg.) (Qhov txaus ntshai (?) Mercury muaj nyob nrog ib feem ntawm cov iav raj, uas tau muab sib cais tag nrho los ntawm cov khoom siv hluav taws xob. Tsuav koj tsis tawg lub iav, cov tshuaj mercury nyob qis qis kom raug kaw …)

Kauj Ruam 3: Yog li Peb Tau Txais Dab Tsi?

Kuv xav tias peb CFL "Ballasts" qhia ntawm no yog los ntawm 60W-sib npaug IKEA plaub-raj teeb, tsis qhia npe 75W-sib npaug teeb teeb, thiab 100W-sib npaug teeb teeb. Cov kab hluav taws xob zoo li zoo sib xws (saib nplooj ntawv tom ntej), thiab lawv muaj cov khoom sib xws. Lwm CFLs yuav muaj qhov sib txawv sab hauv; Cov neeg muag khoom tab tom ua IC-raws CFL Ballast circuits nrog ntau yam kev txhim kho zoo. Cov peb no zoo li muaj cov kab lus "ruam" zoo nkauj. (nruab nrab) High Voltage diodes (nruab nrab) Cov khoom siv hluav taws xob muaj zog - qee qhov ntawm no muaj cov coj zoo ntev yog li lawv tuaj yeem raug txiav tawm yam tsis tas yuav tsum tau muab tshem tawm. Loj Inductor - ntawm qhov kev txiav txim ntawm 2.5 milli -Henries rau lub teeb 20W. Me Inductor - tus nqi tseeb tsis paub. Toroidal Transformer (muaj txiaj ntsig zoo rau Joule Thief!) High Voltage Transistors lossis Mosfets Assorted resistors. High-voltage, High-temp "spaghetti"-qhov no feem ntau yog silicone coated fiberglass; cov khoom muaj txiaj ntsig hauv qee qhov kev thov, thiab nyuaj rau nrhiav thiab kim yog tias koj yuav tsum yuav nws. Lub Fluorescent Tube nws tus kheej - yog tias qhov no tseem zoo, koj tuaj yeem ua tej yam xws li hloov lub ballast nrog DC inverter thiab muaj lub roj teeb siv CFL.

Kauj Ruam 4: Txhua Yam Uas Ua Li Cas - Lub Teeb Pom Teeb Ua Haujlwm Li Cas, Xijpeem?

Lub teeb fluorescent yog lub raj tso pa tawm. Nws ua haujlwm me ntsis zoo li lub raj strobe, thiab me ntsis zoo li LED. Thaum nws tau ua haujlwm, nws yuav zoo siab tso cov hluav taws xob loj heev ntws los ntawm qee cov pa roj ionized. Txhawm rau tiv thaiv nws ua hluav taws xob ntau heev uas nws hlawv tawm lossis tshuab fuses, koj yuav tsum txwv qhov tam sim no nrog qee yam ntawm cov hluav taws xob sab nraud (qhov no yog ib feem uas zoo ib yam li LEDs.) Qhov no yog lub hom phiaj tseem ceeb ntawm cov teeb hluav taws xob. (Lwm txoj haujlwm ntawm ballast yog mus rau qhov ntawd "ib zaug nws tau ua haujlwm" lub xeev. Koj yuav pom tias qhov ballast yog tus inductor. Qhov no vim tias tus inductor tuaj yeem ua tus txwv tam sim no 'rau AC tam sim no yam tsis tau siv lub zog li txoj kev tiv thaiv (raws li siv rau LEDs) yuav. Ib qho ua kom zoo. Tam sim no dhau los ntawm tus inductor (thiab yog li lub teeb, txij li nws yog ib qho kev sib txuas hauv Circuit Court) yog sib piv rau AC zaus, thiab qhov inductance ntawm tus inductor. Yog tias koj puas tau pom qhov sib nqus nkaus xwb ballast los ntawm tus qauv teeb pom kev zoo, koj yuav muaj lub tswv yim loj npaum li cas inductor xav tau ntawm 60Hz AC uas tawm ntawm phab ntsa.

Kauj Ruam 5: Tus Compact Fluoresent txawv li cas?

Yog li dab tsi txawv ntawm Compact fluorescent? Ib lub raj CFL zoo nkauj npaum li ib yam li lub teeb fluorescent ncaj; nws cia li quav. Txhawm rau ua kom ballast me dua, peb yuav tsum txo qhov inductor li cas. Txij li tam sim no yog sib piv rau qhov inductance THIAB qhov zaus, peb tuaj yeem ua tus inductor me dua los ntawm kev nce zaus! Yeej, cov khoom siv hluav taws xob hauv CFL (lossis hauv "hluav taws xob hluav taws xob" rau cov pa roj fluorescents) muaj cov kab hluav taws xob uas yuav ua rau HIGHER FREQUENCY AC los ntawm qhov ib txwm siv 60Hz. Feem ntau, AC cov tswv yim raug kho thiab lim mus rau High Voltage DC (HV diodes, lub tshuab hluav taws xob), thiab tom qab ntawd qee qhov oscillator (lwm lub kaus mom, toroid, me me inductor) tau siv los tsav qee qhov HV transistors los tsim qhov kawg uas yog tseem hais txog tib qhov hluav taws xob, tab sis ntawm qhov ntau zaus ntau dua li qhov qub. Txoj hauv kev no, qhov kawg tam sim no-txwv inductor ("loj inductor") tuaj yeem me dua.

Kauj Ruam 6: Dab Tsi Yog Dab Tsi?

Tau saib ntawm lub siab heev ob peb lub qhov muag tuag CFL, Kuv xav tias muaj peev xwm tsim nyog los taw qhia qee qhov laj thawj uas lawv mus tsis zoo.

Ua ntej, tau kawg, lub raj nws tus kheej tuaj yeem mus rau qhov tsis zoo, tau xau ntau dhau lub tshuab nqus tsev, lossis ua kom cov hlau ntau dhau sab hauv, lawv tsuas yog ua haujlwm. Thaum cov neeg tsim khoom hais koj lub neej dhau los rau qhov muag teeb CFL, qhov no yog hom tsis ua haujlwm uas lawv muaj hauv siab.

Hmoov tsis zoo, ntau ntawm CFLs zoo li mus rau qhov tsis zoo hauv cov khoom siv hluav taws xob. Kuv tau pom lawv haus luam yeeb, tso cov ntxhiab tsw phem, thiab txawm tias muaj txim (txaus ntshai, ua rau muaj qhov tshwm sim tuaj yeem ua rau tawg ntawm lub teeb ci.) Kuv tau coj lawv sib nrug thiab pom tseeb tias muaj cov khoom siv hlawv. Kuv xav liam qhov no ntawm "kev xa khoom pheej yig", tab sis kuv tau muaj tus lej ncaj ncees ntawm lub npe CFLs nrog cov teeb meem zoo sib xws. Txawm tias qee qhov hluav taws xob hluav taws xob hauv cov khoom siv hluav taws xob fluorescent. Hnov. (Nws zoo li yuav zoo dua.)

Hmoov tsis zoo, tsuas yog vim tias ib feem ntawm lub rooj tsav xwm hluav taws xob tau hlawv, tsis txhais tau tias yog qhov tivthaiv uas ua rau tsis zoo thaum pib.

Tus neeg ua phem loj zoo li yog cov khoom siv hluav taws xob uas lim HV DC. Kuv tau pom cov no nrog bulging thiab txawm tias tawg. Yog tias koj nyeem cov ntawv tshwj xeeb capacitor, koj yuav pom tias cov khoom siv hluav taws xob no muaj qhov kawg lub neej los pib nrog, thiab lub neej ntawd poob qis dua qhov ua haujlwm kub nce. Sab hauv lub qhov cua nkag tsis zoo nrog 20W ntawm lub zog tau tawg tawm nyob ze ua rau qee qhov kub zoo nkauj. Muaj YUAV TSHUAJ kub siab, tab sis kuv tsis tau pom dua ib qho hauv CFL:-(Thaum lub hau tawm mus, HV oscillator tau txais lub zog tam sim no tsis siv DC, uas kuv xav tias nws tsis nyiam, thiab nws tsis xav tsis thoob tias lwm yam tsis raug ib yam nkaus. Qee qhov, tab sis tsis yog txhua yam, CFLs muaj lub fuse …

Cov inductors yog cov khoom zoo nkauj heev; tej zaum lawv yuav zoo tshwj tsis yog lawv qhia pom tseeb tias raug hlawv. Lub kaus mom uas tsis siv hluav taws xob yog tej zaum zoo ib yam, thiab koj tuaj yeem yooj yim sim lawv rau luv nrog siv lub multimeter. Kuv tsis tau sim ib qho ntawm cov transistors …

Kauj Ruam 7: Kuv Yuav Ua Li Cas Nrog Qhov?

Yog tias lub raj tseem zoo, koj tuaj yeem siv nws nrog lwm hom ballasts lossis inverters. Daim duab qhia pom qhov pheej yig tshaj CCFL inverter tau teeb tsa sab hauv lub kauv ntawm CFL; lub teeb tam sim no ua haujlwm ntawm 5V (thiab ua haujlwm txog 3W …) Tshawb nrhiav hauv internet kom paub cov lus qhia ntxaws ntxiv. Qhov capacitors, resistors, thiab diodes yuav muaj daim ntawv thov dav dav, yog tias lawv zoo. Rau kuv, cov khoom muaj txiaj ntsig yog cov inductors; nws tuaj yeem nyuaj nrhiav inductors hauv kev nyiam ua lag luam hauv khw, tshwj xeeb tshaj yog nyob rau hauv qhov kev hloov pauv tam sim no muaj nyob hauv CFLs. Lub toroid tuaj yeem yooj yim tshem tawm ntawm nws cov cua qub thiab rov ua haujlwm rau lwm lub hom phiaj, xws li tus qub Joule Thief ib leeg-cell LED tsav tsheb. Qhov me me inductor zoo li nws yuav haum rau ntau qhov "thev naus laus zis qis" hloov pauv daim ntawv thov siv hluav taws xob, xws li Roman Dub Hloov tus tswj hwm lossis lwm tus tsav tsheb LED dawb. Tus loj inductor kuv tsis paub tseeb; hauv qhov xwm txheej tsis zoo nws tseem muab cov tub ntxhais me me uas tuaj yeem rov ua haujlwm rau lub hom phiaj tshwj xeeb. Yog tias koj tsis siv lub raj, sim muab nws pov tseg ntawm qhov chaw rov ua dua tshiab uas lees txais lub teeb ci. Tej zaum lawv yuav tsis zoo siab heev kom tau txais … daim, tab sis lawv yuav tsum tsis txhob mloog TOO ntau li ntev tau yog iav tsis khov.
