Kwezinye izimo, lapho ukukhanya kucishiwe, ukukhanya okukhanyayo. Umcimbi awunakubi emehlweni, ngaphandle kokugcina impilo yamalambu. Kungani lokhu kwenzeka nokuthi ungabhekana kanjani nakho, ake sixoxe ngokuqhubekayo.
Imbangela Cha. 1 yokuqwayiza kwamalambu okulondolozwa kwamandla
Uma ushintsha nge-LED noma i-Neon Backlight, lapho ufaka amalambu ezomnotho (abizwa nangokuthi amalambu wokonga amandla noma ama-fluorescent acwebile) lapho ukukhanya kucishiwe, baqala ukugcwala. Isimo esifanayo sibonwa ngamalambu athile (Chinese Chinese) ahoxa. Ukufakwa kwesikhashana kwesikhashana kwenzeka - kumasekhondi ahlukene - nokuvalwa okusheshayo. Iphinda lokhu kaningi njalo ngemizuzwana embalwa.
Isizathu silula. I-LED LED noma i-Fluorescent Light Bulb lapho ukukhanya kuvaliwe ngenxa yokuba khona kwe-Backlight LED Power Partere kanye nezici zedivayisi yalezi zibani. Ngokungafani namalambu we-incandescent, amalambu wokonga amandla namandla aholwa yi-DC 12 v. Kepha axhumeke kwinethiwekhi ka-220 v, futhi ukuguqulwa kwenzeka ngaphansi kwesibani, lapho kufakwa khona i-diode Ukuguqula ama-220 v ukushintshana kwamanje ku-12 v.
Shintsha ukujikeleza kwe-backlight Power Supply kudala izimo zecala le-capacitor yesibani
Lapho uhumusha i-switch to the state "khubaza", kusekhona i-LED / Neon Lamp Power Supply Chain, yingakho ekhazimulayo. Kulesi sakha, ukugeleza kwe-microcorusent - akusadingeki ukubonwa. Bancane, kepha banele ukugcina i-capacitor esingutsheni ukuze baqongelele icala elanele lesi sibani (esifakwe kwisibani esingaphansi). Ngenxa yalokho, isibani sikhanyisa. Kepha, njengoba icala lisencane kakhulu futhi akukho okudla okujwayelekile, isibani sihamba ngokushesha. Ngakho-ke kuvela blink.
Kwesinye isikhathi - ngokushintshwa okuthile - amalambu awasho lutho, kepha ashise ekushiseni. Lokhu kungenxa yokuthi ukumelana okumi emjikelezweni wamandla we-backlight akwanele. Njengomphumela wesamanje, kwanele ukugcina imali encane ye-condenser. Ngakho-ke, kuvela ukuthi izibani zikhanyiswa lapho kuvaliwe ukukhanya. Izibani zeqhwa zihlupheka kaningi (kuholwa). Izindlela zokulwa nalesi simo ziyefana nokuqhafaza.
Isihloko ngesihloko: Ungayisebenzisa kanjani izimpumputhe
Isikhundla lapho ukukhanya kukhanya lapho ukukhanya kucishiwe akukubi nje kuphela kwamehlo. Kunomphumela owodwa owengeziwe: Isibani ngasinye senzelwe inani elithile lokuvalwa kokuvalwa. Lapho ufiphaza ukwahlukana kwesekhondi, lo mjikelezo wenzeka. Ngomzuzu lapho kungenzeka kube ngu-10 nokuningi. Kuyacaca ukuthi maduze nje isibani sehluleka. Ngakho-ke bhekana neqiniso lokuthi lapho ukukhanya kucishiwe, ukukhanya okukhanyayo, kuyadingeka ngokushesha ngemuva kokutholwa.
Susa inombolo yenkinga 1
Ngemuva kokuqonda ukuthi kungani ukukhanya okusindisa amandla kukhanya lapho inkinobho isicishiwe, kulula ukuphakamisa isixazululo senkinga:
- Shaya i-Microton Pass chain ngokususa isibani se-backlight ekushintsheni.
- Shintsha amapharamitha akwamandla e-backlight ahlinzeki ukuze amanje anele ngecala le-capacitor.
- Bopha imisinga ku-chain ngokumelana okuncane.
- Faka esikhundleni sokushintshela kwimodeli ngaphandle kokukhanyisa noma ukubeka amanye amalambu.
Kungani ama-blinks ahole isibani esikhanyayo lapho ukukhanya kucishiwe
Uma sikhuluma nge-chandelier enezimpondo eziningana, kunenye indlela - ungabeka isibani se-incandescent kwenye yezimpondo. Indlela ilula, kepha iyasebenza. Uma ukukhanya okukodwa kufiphala i-flicker, nalesi simo kuzofanela silwe ezinye izindlela. Ngokufakwa esikhundleni kwezibani namalambu, mhlawumbe akukho mibuzo okuzophakama, kepha ngezinye izindlela abangaba ngazo.
Sisusa i-backlight
Ekushintsheni nge-backlight eyakhelwe ngaphakathi, kunebhodi lapho i-LED itholakala khona noma isibani esincane se-neon, ukumelana noxhumana nabo (imvamisa njengentwasahlobo). Le mali ingaphansi kwe-cap cap encane yepulasitiki ngemuva kokushintshwa kokushintsha. Ukuze ufike kukho, udinga ukuhlukanisa ukushintshwa.
Sinqamula ukushintshwa ukuze sifike kwisembozo
Isembozo singenza isipikili noma isikulufa. Ngemuva kokuyisusa, ohlangothini olubuyela emuva, sithola imali.
Ngemuva kwesembozo kufakwe ibhodi elincane le-backlight
Thatha le mali. Akanamathelwe kunoma yini, avele alungiselele futhi asuse kusuka kukhiye. Mboza ngaphandle kokukhulisa ukufaka indawo, siqoqa ukushintshwa hlola ukusebenza. Konke kufanele kusebenze, ngaphandle kwezinto ezimbili: i-baclight ayishisi lapho ukukhanya kucishiwe kanye namalambu wezomnotho noma aholayo awashintshi.
Shiya ukukhanya okukhamuleni ngokushintsha amapharamitha we-Power Chain
Akuwona wonke ama-swaylit angenziwa asetshenziswa amabhodi. Amamodeli wesabelomali amaningi enziwa lula: Ukumelana nakho kuthengiselwa i-diode futhi lesi sifunda sisethwe ngokufana nezinkinobho zokushintsha (njengasesithombeni ngezansi).
Isibani se-backlight ekushintsheni singaqoqwa kanjalo
Kulokhu, ungaphonsa / uthenge i-LED ne-Resior bese uthola ukushintshwa okujwayelekile ngaphandle kwe-backlight. Kepha ungashintsha amapharamitha wale ntengo ukuze ubukhazikhazi basebenze, futhi izibani ziyahlanya noma zishise lapho ukukhanya kucishiwe ngeke. Ukuze wenze lokhu, kuzodingeka ungene esikhundleni sokuphikiswa - ukubeka ukumelana:
- Okungenani ama-220 kω, uma isibani esikhange nge-neon lamp;
- Okungenani i-470 com noma i-680 com nge-backlight kwi-LED (ekhethiwe endaweni).
Ngaphezu kwalokho, i-In4007 Diode ifakwe ku-chain yokumelana, i-cathode iye kumphikisi. Ukufakwa kwesibili kwe-diode kuthengiselwa isibani se-backlight. Ngenxa yalokho, ukuhlinzekwa kwempahla kuzobukeka ku-Photo.
Isikimu sokukhanya okuthuthukile
Ukuqeda ukufiphala kwamalambu bese ugcine ukukhanya okukhazimulayo ku-switch, siphonsa umphikisi wakudala, sibeka entsha nge-diode. Ngemuva kwalokho, ukushintshwa kungaqoqwa bese kufakwa endaweni.
Susa izibani ezifiphele lapho ukukhanya kucishiwe
Ezimweni eziningi, inkinga inyamalala. Uma isibani sisakhanya, kuyadingeka ukufaka esikhundleni sokumelana nokukhulu. Lokhu akuvamile, kepha ...
Dala i-Parallel Lamp Chain ngokumelana okuncane
Uma uxhuma umphikisi ngokufana nesibani, okukhona manje kuzoqhubeka nokushisa kwalo, i-capacitor yesibani izohlala ngaphandle kwenkokhiso yokukhanya. I-Resistor imvamisa ithathwa ku-50 kω namandla ka-2 W, izintambo zifafazwa, bese zihlukaniswa, zishiya izintambo ezimbili kuphela zokuxhuma. Ingapholiswa ngetheyipu, ingaba yi-shrunk tube.
Okokuqala, faka indawo yokuxhumana yabaqhubi kanye nemilenze yokumelana, ngemuva kolunye ungqimba lokufakelwa, okubuye kuvale ukumelana. Ama-Currents mancane, afudumele, uma kunjalo, angasho lutho kakhulu, kodwa ngokufakwa okuhlosiwe okunjalo, lokhu kuguqulwa kuphephile.
Faka ngokucophelela zonke izindawo ngaphandle kokuzehlukanisa
Kunezindlela ezimbili zokufaka le proniser: ebhokisini lokuhlangana noma ngqo esibani. Kubalulekile kuphela ukuthi ixhumeke ngokufana nesibani.
Kungabonakala lapho i-resistor kumele ixhunywe khona, kepha akudingekile ukwenza esithombeni: kulula ukufushane
Ngezindawo ezifanayo, xhuma umphikisi olungiselelwe ngaphambilini. Kuphephe kakhulu. Ebhokisini lokuhlangana, ukuxhumana kwenzeka ngendlela efanayo. Udinga ukuthola izintambo ezimbili eziya esithangeni, nakulabo oxhumana nabo abazoxhumana nabaqhubi abengeziwe. Ngemuva kokuhlelwa kabusha okunjalo, ukukhanya okukhanyayo ngeke kube. Kepha uma unamandla kugesi, yinhle kakhulu. Futhi siphinde sikukhumbuze ukuthi yonke le misebenzi kufanele yenziwe ngesihlangu se-Power-off-off.
Imbangela # 2 nokuqedwa kwayo
Uma une-switch ngaphandle kwe-backlight, futhi isibani se-LED noma umnotho siyavuka lapho ukukhanya kucishiwe, khona-ke kukhona iphutha ekuxhumekeni. Ngokunokwenzeka, ukushintshwa akuphukile ekushintsheni, njengoba kufanele kube khona, kepha zero. Ngaphezu kwalokho, kuyingozi enkulu, kuholela kulesi simo - ukuqwayiza kwezibani ezithile.
Lapho i-switch ixhumeke kahle, isigaba sephula ukhiye.
Kuqedwa ngokulungisa iphutha - kuyadingeka ukubheka ukuthi yiziphi izintambo zesigaba futhi xhuma kahle inkinobho. Uma kulayini wonke ama-switches axhumeke ngokungalungile, ungawela izintambo kusihlangu. Uma ingxenye kuphela - kufanele ukwenze lokhu ku-switch exhunywe ngokungalungile.
Imbangela # 3: Kungani ukukhanya kukhanya uma konke kuxhunyiwe kahle
Kwesinye isikhathi ukushintshwa ngaphandle kokukhanya okukhazimulayo, futhi isigaba sivele, futhi ukukhanya kukhanya ngokukhanya lapho ukukhanya kucishiwe. Lapho-ke isizathu sisesimweni esingesihle se-wiring. Kungenzeka ukuthintwa, futhi mhlawumbe ezinkingeni ngokwahlukana. Uma oxhumana nabo bengaqiniswa, babuyiselwa, babuyisela emuva, khona-ke izinkinga nokufakelwa kuxazululwa kuphela ngokubuyiselwa okuphelele kwe-wiring.
Umzuzu owodwa: Izinkinga zokufakwa - kusho ukuvuza okuphezulu kwamanje. Uma unakho kulayini we-RCO, kuzovamisa umugqa. Uma i-UZO ingeyona futhi i-wiring indala, awuyichazi. Esikhundleni salokho, kungenzeka ukuthi unqume ukusebenzisa i-Ohmmeter futhi uhehe ochwepheshe. Uma kwenzeka kulimala okukhulu, ungaqiniseka ukuthi le nkinga ingalungiswa nge-multimeter kanye nezintambo zezintambo emhlabeni. Hhayi-ke, futhi uBlunsa isibani ngukubonakaliswa okuyimfihlo ukuthi ukufakwa konakaliswe futhi kunemisinga evuvukala ebalulekile.
