Kutheni ezibengezelayo isibane LED kunye izibane? ezibangela kunokwenzeka kwaye kusonjululwe ingxaki le

Namhlanje, izibane ezonga umbane athandwa kakhulu ngenxa yobomi babo elide inkonzo nombane ephantsi. Noko ke, labenzela ithinzi, njengoko abathengi ngakumbi nangakumbi kukhetha LED izinto zokukhanya.

Kakade ke, wonk 'ufuna eninzi imali ezifunyenwe yi ifowuni ukuze isebenze kakuhle kwaye musa esingenakubangela naliphi na inkathazo. Noko ke, maxa wambi kuyenzeka na ukuba ukhanyiso odanyazayo kunye izibane. Yintoni na isizathu? Ngaba ndiya kuyishiya luminaire ngaphandle ingqalelo? Nayo yonke le mibuzo zama ukuqonda inqaku.

idanyaza isibane Kutheni LED: Isizathu ixhaphakileyo

Le ukusilela ngokuqhelekileyo kwenzeka abaninzi eneji-ugcino, kwaye uninzi LED wezibane. yonke Ingongoma kwefowuni. Ingxaki yeyokuba olu hlobo kwezixhobo anikwe amandla ombane ayi-12 V. nje yaziwa, ongachazwanga kule izindlu ze-network. Kwiimveliso ungakwazi ukusebenza ukususela AC amandla 220 V, eyakhiwe isibane converters isiseko ombane. Ziqulethe uluhlu capacitor, nesigxina-Ukugcinwa, ngoko ukuba kukho "ucinezelo", kwaye ukukhanya liyakhanya emva ngokunqakraza kwi iswitshi. Ngaloo ndlela, iyunithi Ukukhanyisa akasinikanga ngqo kodwa kuphela lokuguqulela.

Ukuze siqonde isizathu sokuba ezidanyazayo LED isibane izibane, kuyimfuneko ukuba siqwalasele siseko ukusebenza iswitshi.

Ilayithi luvuliwe ngaxeshanye kunye nayo, equka i-LED kunye resistor amandla eliphantsi. Ekubeni izibane iqhosha "licwangcisa" ukutya chandelier chain, kodwa kwangaxeshanye indlela enjalo Uyasiphumelela current encinane. ixabiso layo ayanelanga ukuba ityala ngokupheleleyo capacitor yokuqala elahliweyo kwi ibhalbhu Converter. Emva kwethutyana abanye kusekho lakha phezulu, kwaye kukho "ukuqala" isibane. Kodwa umlinganiselo wamandla incinane kakhulu, ngoko breaks isixhobo obunjengombane kwaoko uyacima, yaye yonke into kwakhona ngokuphindaphindiweyo. Oku kudla ichaza isizathu sokuba ezidanyazayo LED isibane izibane. Noko ke, kukho izizathu ezininzi kule ukusilela. Bona eziqhelekileyo, ngoko musa Ungabakhupheli ngaphandle.

izizathu Common

Siza kuqhubekeka ukuqwalasela asilotyala zalapho zokukhanya. Ukuze achaze isizathu sokuba lo ezidanyazayo LED isibane izibane, kufuneka sinikele ingqalelo oonobangela nandzu kunokwenzeka. Mhlawumbi le nto:

• uqhagamshelo engafanelekanga okanye ukufakelwa kwenkqubo izibane.
• Umsebenzi. Xa uthenga ngexabiso kakhulu ibhalbhu ukukhanya Chinese, akuyi kufuneka silindele lukhulu kuyo.
• LED iswitshi ukukhanyisa. Undoqo isoloko kakhulu ifakwe eyongezelelweyo "isibane" evumela ukuba ufumane umthombo ukukhanya ebumnyameni. Ingxaki kukuba LED sisebenzisa womnatha elinye kunye chandelier, nto leyo esisizathu sokuba amaxesha amaninzi ephindaphindayo yesekethe zenzeke.
• Sagcina ubomi inkonzo izibane LED.

Mhlawumbi oku ichaza isizathu sokuba idanyaza ukukhanya LED. Kwakhona ekufaneleke ukuba siyicinge ngaphantsi okuba ezibangela ukusilela. kwiimeko ezinjalo kwenzeka ngaphantsi rhoqo.

izinto kunokwenzeka

Kancane ukuba uphendule umbuzo othi, "Kutheni kubaneka LED isibane" uba enye yezi iziphene:

• Ukuze onakalise nayiphi na inkcukacha kwisixhobo chip.
• uphazamiseko womnatha kwenzeka kakhulu. Abavelisi akafanga ngenxa yokwanda ngamandla kakhulu. Oku kwenzeka kunqabile kakhulu, kodwa ukuba ukhe uye kwindlu ngaphandle zonke izibane, le ngxaki inokuba kuyo.
• It wazidiliza umbane eziluzizi. Esi sixhobo asetyenziselwa utshintsho kwamagingxi nokukhanya kwelo gumbi.

Abanye abantu neze okukruqulayo ukuba ukuqhwanyazaemva LED isibane izibane, kunye nabanye ukuhlawula ingqalelo kuyo. Kodwa ungacingi ukuba ezi zinto zokukhanya.

Kutheni indiva Morgan isibane

Ukuba ifowuni isetyenziswa ukukhanyisa izakhiwo zobugcisa, inokukuzisela yingozi kakhulu. Kulo mzekelo, ungenza ushiye yonke into njengoko kunjalo. Noko ke, xa kufikwa kwigumbi lokutyela, ngoko ukukhanya zidanyaza kungadala ingxaki enkulu.

Isibakala sokuba yokudanyaza luyingozi kakhulu iliso. Ukuba igumbi lonke ixesha odanyazayo ukukhanya, amehlo uya kufumana udinwe kakhulu ngokukhawuleza, yaye umsebenzi ngokwasengqondweni uza ingathinteleki. Oku yingozi ingakumbi kubantwana abaselula.

Kwakhona uqhambuko ngokuphindaphindiweyo angadala nokuhlutha unesathuthwane xa umntu onesifo kwesi sifo kakhulu. izibane ukuqhwanyazaemva ibe nefuthe elibi izilwanyana, ingakumbi iikati. Ezine-enemilenze baqalise ukuba siziphathe ndikungxamele ngakumbi kwaye uqale ukubonisa ndlongo.

Ngoko ke, ukuba LED idanyaza ukukhanya emva kokutshintshela off, kuyimfuneko ukulungisa le ngxaki. Kwaye ukuba zenjenjalo ngokukhawuleza kangangoko kunokwenzeka. Kwakhona, kufuneka kuthathwe ukuba idanyaze neendawo lomlingani ayidluli-20%. Akwanelanga ukuba athenge imitha ukukhanya.

Ngoku kuziguqulela izindululo malunga nolungiso kwezibane olungachananga.

Ezibengezelayo ukukhanya LED: ntoni ukwenza ntoni?

Indlela yokuqala - utshintsho kwi parameters wokusetyenzwa amandla ilayithi wesekethe. Kukho iindlela ezimbini lungalungiselelwa ngayo:

• Kunye nokusetyenziswa ibhodi apho ibekwe resistor compact kunye LED.
• Xa uqhagamshele ngaxeshanye, le resistor standard LED-elements.

Kwimeko yokuqala siza kuba ixesha elide kakhulu silungise. Bekuya kuba lula nje ukususa isigxina. Kwimeko yesibini, yonke into lula kakhulu. Ungazama ukutshintsha resistor endaweni unamandla ngakumbi. Ngenxa oku kunciphisa yangoku iphuma ekondensa, kunjalo nje kuya angemi.

Xa indawo resistor kuyimfuneko ukuqwalasela amandla alo kunye nohlobo isixhobo ukukhanyisa. Kuba LED izinto kwemali ezifanelekileyo zalathisi 470 okanye 680 ohms.

indlela 2

Kule meko kuyimfuneko ukuze kuphunyezwe le uxhulumaniso engumzekelo izibane kunye neziphaluka kunye nokumelana eliphantsi. Ngenxa imisinga ayahamba ilayithi akayi eziyintlanganisela kwi ekondensa. Endaweni yoko, baya kungena umxokelelwane, nokukhanya, okha ayeke ezibengezelayo.

Ukuze wenze oku, kufuneka ukuthenga resistor umthamo ongekho ngaphezu kwe-2 watts kunye ukuvimba ababezibiza ngayo ohms 50. Ukwenza kube lula ukudibanisa kuyo, kufuneka ukuba solder kwiingcingo ukuya iziphumo zawo. Emva koko, kuyimfuneko ukuba ikheswa resistor. Ngenxa yoko, kuqala ukuba lumakishwe siyehla ingongoma nganye ngelotha, emva koko resistor tsala shrinkable tube (kulapho ngcono) bokuxhathisa kwaye uvale lwezindlu.

Ilungiswe yi nomxokelelwane enxulumene ngokunxuseneyo ukuya isibane. Kucetyiswa ukuba basebenzise ibhokisi kuhlangana.

indlela 3

Abanye abantu basebenzisa capacitor endaweni resistor. Kulo mzekelo, kufuneka uthenge le yunithi, ogama amandla 400 V. Le xhulumaniso lwenziweyo ngendlela efanayo - ngaxeshanye. Kulungile ukusebenzisa ibhokisi kuhlangana.

Le isisombululo elula nesebenzayo ukunceda ukulawula umsebenzi izibane Morgan.

Ukuba iingxaki usambathisa

Ukuba kukho ukuvuza ngoku, kuba yingxaki ngakumbi kakhulu. Kulo mzekelo, kufuneka ukufumana umqhubi oxides pad kwaye uhlambe ngawo. Kwakhona, kuyimfuneko ukuba solder udibaniso.

Kwezinye iimeko, le langoku 'ukuya' ngenxa yokugquma amahlwempu, ngoko kufuneka achithe ixesha elininzi ukufuna ukuvuza. Xa umgca sifanele matshini, kuba nalo rhoqo "inkqonkqoza". Ukuba oku kuyenzeka, ngoko inokuba ingxaki ilele kweentambo embi. Ukuze ubone "ikhefu" yayo indlela elula yokusebenzisa i multimeter.

Ukwazi isizathu sokuba ezibengezelayo isibane LED kunye izibane, ungenza ukusombulula ingxaki ngokwakho. Noko ke, abo "na" kunye umbane, ayikhuthazwa ukuba kunjani. Kubhetele ukuba ukubiza inkosi. Lomntu ke onobu bugcisa abanezakhono iya kuqinisekisa ngeliso lenyama, yintoni isizathu sokuba ukusilela.
