Waa maxay Waxyaabaha Saameeya Qulqulka Iftiinka LED-ka ee AC?

1. LED-free AC laftiisa dhibaatada tayada: 1. Chip-ka LED-ka ee la isticmaalay ma fiicna, oo iftiinka dhalaalku wuu dheereeyaa. 2. Waxaa jira cillado ku jira habka wax soo saarka. Kala-baxa kulaylka ee chip-ka LED si fiican loogama qaban karo lugta PIN, taasoo keentay heerkulka xad-dhaafka ah ee chip-ka LED-ka kaas oo ka sii daraya hoos u dhaca chip-ka. 2. Shuruudaha ku isticmaala: 1. LED waa wadida qulqulka joogtada ah. Qaar ka mid ah LED-yada waxay isticmaalaan darawalada danabka si ay u sameeyaan attenuation LED. 2. Hadda darawalku wuu ka weyn yahay xaaladda darawalka ee la qiimeeyay. Dhab ahaantii, waxaa jira sababo badan oo suuska iftiinka ee alaabta LED-free AC. Furaha waa dhibaatada kulaylka. Inkasta oo warshado badan oo aan fiiro gaar ah siinin dhibaatada kuleylka kuleylka, alaabooyinkan LED-yada labaad ayaa loo isticmaali doonaa waqti dheer. Alaabooyinka LED-ka ee diiradda saaraya kuleylka kuleylka waa inay ahaadaan kuwo sarreeya. Iska caabbinta kulaylka ee chip LED laftiisa, saamaynta koollada lacagta, saamaynta kulaylka ee substrate, iyo dhinaca kolloid iyo line dahab ah ayaa sidoo kale la xidhiidha suuska iftiinka. Saddex arrimood oo saameeya tayada iftiinka iftiinka ee nalalka LED, marka hore, nooca nalalka cad ee LED ayaa dooranaya. Tani waa muhiim. Tayada LED-free AC waxaa la odhan karaa waa arrin aad u muhiim ah. Tusaale ahaan, isku mid ah waxaa ka muuqda chip of chip of chip 14mil ah, iyo nalalka cad cad LED koobay by xanjo hoose iyo xabagta cad iyo koollada baakadaha ka samaysan xabagta epoxy caadiga ah waxaa shid in a deegaanka 30-degree ah. Kumanaan saacadood ka dib, xogta la dhimay waa 70% suuska iftiinka; Haddii nooca D nooca D ee koollada hooseysa ee hooseysa lagu duubo, isla deegaanka gabowga, suuska iftiinka 1,000-saac waa 45%; , Qulqulka iftiinka 1,000-saac waa 12%; haddii qaybta B ay ku jirto xabag-yar oo hooseysa, isla deegaanka gabowga, kumanaan saacadood oo iftiin ah -3%; haddii Class A xabagta suuska hooseeya, isla deegaanka gabowga, kumanaan saacadood oo iftiin ah, kumanaan saacadood oo iftiin ah Dechat waa -6%. Marka labaad, heerkulka deegaanka shaqada ee kuul nalalka LED. Marka loo eego xogta marka hal nalka cad ee LED uu gabow yahay, haddii nalka cad ee LED uu leeyahay hal shaqo oo iftiin ah, isla markaana, heerkulka deegaanka ee uu ku yaal waa 30 digrii, ka dibna heerkulka bracket ee LED-free AC ah. ma wado shaqada LED. Waxaa ka badnaa 45 shahaado. Waqtigaan, nolosha LED-kan ayaa noqon doona mid ku habboon. Haddii ay jiraan 100 nalal cad oo LED ah oo isku mid ah isla waqti isku mid ah, farqiga u dhexeeya iyaga waa 11.4mm oo keliya, ka dibna heerkulka heerkulka bracket ee nalalka cad cad ee LED-ka ah ee ku wareegsan tuubada laambada ayaa laga yaabaa inaanay ka badnayn 45 digrii, laakiin dhexe Tusmada laambaddu waxay ku taal badhtamaha laambadda. Nalalka cad cad ee LED waxa laga yaabaa inay gaadhaan 65 darajo heerkul sare. Waqtigaan, tusaha nalka LED waa tijaabo. Dabadeed, nalalka cad cad ee LED-ka ah ee lagu soo ururiyay aragti ahaan waxay u dhaq-dhaqaaqi doonaan iftiinka si dhakhso ah, iyo iftiinka cad ee LED ee ku wareegsan nalalka ayaa noqon doona mid gaabis ah. Si kastaba ha ahaatee, qof kastaa waa inuu ogaadaa in LED-ku uu ka baqo kulaylka. Markasta oo heerkulku sarreeyo, nolosha LED-ku waa sii yaraanaysaa, heerkulku wuu hooseeyaa, iyo cimriga LED-ka ayaa sii dheeraada. Heerkulka shaqada ee ku habboon LED waa dabcan inta u dhaxaysa 5 ama eber darajo taban. Laakiin tani asal ahaan waa wax aan macquul aheyn. Sidaa darteed, ka dib markaan fahamno cabbirrada shaqada ee ugu habboon ee kuulka nalalka LED-ka, waa inaan xoojinaa shaqada kulaylka kuleylka iyo kulaylka marka la naqshadeynayo nalalka sida ugu macquulsan marka la naqshadeynayo nalalka sida ugu macquulsan. Si kastaba ha noqotee, heerkulku hooseeyo, waa sii dheeraanayaa cimriga LED-ka. Saddexaad, Naqshadaynta cabbirka elektiroonigga ah ee LED-free AC-free. Isha nalka LED-side Module qaabaynta duritaanka nalka LED-ka LED-ka koollada waraabka aan biyuhu lahayn ee Hongyan kab saddexle-in-cab. Saddex-hal qalab shaqo oo culus Sida laga soo xigtay natiijooyinka tijaabada, hoos u dhaca iftiinka cad ee LED, kulaylka yar ee soo baxaya, yar, dabcan, iftiinka yar waa. Sida laga soo xigtay sahanka, naqshadeynta wareegga iftiinka qorraxda ee LED, darawalka hadda ee LED guud ahaan waa 5-10mA; tirada badan ee laambadaha loo isticmaalo in laambadihii, sida in ka badan 500 ama in ka badan Iyo guud ahaan codsiga LED-ka caanka ah ee nalalka wadista socodka waa kaliya 15-18mA, iyo dad yar ayaa naqshadeeyay hadda in ka badan 20mA. Natiijooyinka tijaabada ah ayaa sidoo kale muujiyay in hoos darawalka hadda ee 14mA, iyo daboolka aan la hawo lahayn, heerkulka hawadu wuxuu gaadhay 71 darajo, alaabooyinka hoos u dhaca, 1,000 -saac iftiin leh, 2000 saacadood oo iftiin ah 3% ilaa 3% , 3% qudhuntay waa 3%. Tani waxay muujinaysaa in iftiinka cad ee LED-ka hooseeya ee hoos u dhacaya uu gaadhay xadka ugu wanaagsan ee deegaankan. Si kasta oo ay u weyn tahay, waa dhaawac. Sababtoo ah guddiga gabowga ee gabowga ma laha shaqada kulaylka, kulaylka ay dhaliso LED-free AC asal ahaan ma awoodo inay u gudbiso dibadda. Arinta-jiraabay muujiyey. Heerkulka hawada ee guddidii hore ayaa gaadhay heerkul sare oo ah 101 digrii. Heerkulka dusha sare ee daboolka daboolka hore waa kaliya 53 darajo, taas oo ah daraasiin darajo. Tani waxay muujinaysaa in daboolka caagga ah ee nashqadeysan uusan asal ahaan lahayn shaqada qabashada kulaylka iyo kulaylka. Laakiin naqshadeynta nalka guud, iyadoo la tixgelinayo shaqada samaynta kuleylka iyo kuleylka kuleylka. Sidaa darteed, marka la soo koobo, naqshadeynta xuduudaha korantada ee shaqeynaya ee nalalka LED-yada waa in lagu saleeyaa xaaladda dhabta ah. Haddii shaqada kulaylka-gudbinta kulaylka ee laambaddu aad u fiican tahay, waa caadi in la kordhiyo wakhtiga wadista ee nalalka cadcad ee LED, sababtoo ah nalalka nalalka LED-ku waxay shaqeeyaan. Kuleylka waxaa loo dhoofin karaa dibadda, mana jiraan wax dhaawac ah oo soo gaaray LED-ka, kaas oo ah daryeelka LED-ka. Taas lidkeeda, haddii kuleyliyaha-ku-gudbinta kuleylka kulaylka ee nalka uu yahay mid jilicsan, wareegga waxaa loo qaabeeyey mid yar, si uu u dhigo kulayl yar.
