Kuullaha Laydhka LED Hababka Isku Xidhka Inta Badan La Isticmaalo

Qaabka qaabeynta LED-ka ee codsigu wuxuu ku xiran yahay arrimo badan, oo ay ku jiraan cabbirada LED-ka iyo tirada, korantada gelinta, hufnaanta, maaraynta kuleylka kuleylka, xaddidaadaha cabbirka iyo qaabeynta iyo muuqaallada, iwm. Qaabka qaabeynta ugu fudud waa hal LED. Sababtoo ah diyaaradaha waxaa badanaa looga baahan yahay munaasabadaha codsiga dhabta ah, LEDs badan ayaa loo baahan yahay in la habeeyo oo la isku daro marka loo baahdo si loo buuxiyo shuruudaha codsiga ee cabbirka weyn, dhalaalka sare, bandhig firfircoon, isbeddel midab, iyo shuruudaha u dhigma ee LED iyo darawallada taageeraya. I. Foomka xiriirka 1. Foomamka taxanaha fudud ayaa guud ahaan ku xiran LED1 LEDN qaab fudud oo xiriirin taxane ah, iyo socodka hadda socda inta lagu jiro LED waa siman yahay. Nalalka LED-yada leh astaamo isku mid ah iyo dufcooyin isku mid ah, in kasta oo korantada hal LED ay yeelan karto farqi yar, sababtoo ah LED-ku waa aalad hadda jirta, waxay hubin kartaa in xoogga iftiinka iftiinka uu yahay mid joogto ah. Sidaa darteed, taxanaha fudud ee LED-yada waxay leeyihiin sifooyinka wareegyada fudud iyo isku xirka habboon iyo sifooyinka kale. (Dhibaatada: Isticmaalka taxanaha, marka mid ka mid ah LED-ku guuldareysto, dhammaan nalalka LED-yada ayaa damin doona, taas oo saameyn doonta kalsoonida isticmaalka. ) 2. Foomamka taxanaha ah ee diodka-labada-cirifka leh ee isku-dhafka ah ee Qina diode waxay ku xiran yihiin qaabka isku xirka taxanaha ee la roonaaday ee diode Qina oo is barbar socda. Habkan isku xirka, korantada burburka ee diode kasta oo Zina ah ayaa ka sarreeya tamarta shaqada ee LED. Markaad si caadi ah u shaqeyso, sababtoo ah diode Qina VD1 VDN ma wado, hadda inta badan wuxuu dhex maraa LED1 LEDN. Marka LED-ga waxyeellada leh ee xadhigga LED-ka uu keeno Marka lagu daro LED-yada, LED-yada kale ayaa weli leh qulqulo gudbaya oo dhalaalaya. WeChat xisaabta dadweynaha: Shenzhen LED Chamber of Commerce (habkan isku xirka iyo foomka taxanaha fudud ayaa si weyn u hagaajiyay isku halaynta marka la eego isku halaynta. Labaad, guud ahaan qaabka isbarbardhigga 1. Foomka isku midka ah ee fudud, fudud oo ku xiran LED1 LEDN madaxa dabada isbarbardhigga, LED kasta wuxuu la mid yahay koronto la mid ah, koronto siman. Waxaa laga arki karaa sifooyinka LED. Waxay ka tirsan tahay aaladda hadda jirta, isbeddellada yaryar ee korantada lagu daray LED waxay keeni doontaa isbeddel weyn oo hadda ah. Intaa waxaa dheer, iyada oo ay ugu wacan tahay xaddidaadda tignoolajiyada wax soo saarka LED, xitaa dufcaddii isku midka ah ee LED-yada, waxaa jira kala duwanaansho waxqabad. Sidaa darteed, marka LED1 LEDN uu shaqeeyo, hadda socodka dhex socda LED kasta ma aha mid siman. Waxaa la arki karaa in sinnaan la'aanta qaybinta LED kasta oo hadda jirta ay keeni karto nolosha LED-ka ee hadda inay aad u weynaato, oo xitaa gubato. ( Khasaaraha: Inkasta oo habkan isku xirka uu yahay mid fudud, laakiin isku halaynta maaha mid sarreeya, gaar ahaan codsiyada kiisaska tirada badan ee LED-yada. ) 2. Qaabka isku midka ah ee isbarbardhigga madaxbannaan ayaa loogu talagalay isku halaynta isbarbardhigga fudud. Qaabka isbar-bar yaaca ee madaxbannaan ayaa ah hab wanaagsan. Mid kasta oo LED sidaan oo kale ah wuxuu leeyahay hadda la hagaajin karo (drive Voutput terminal waa L1 Ln) si loo hubiyo in hadda ku qulqulaya LED kasta waa gudaha xadka shuruudaha, oo leh saameyn wanaagsan oo wadista, hal ilaalin LED ah oo dhameystiran, ma saameynayso LED kale. shaqeeyaan marka ay cillado, oo la jaan qaadi kara sifooyinka LEDs kala duwanaansho weyn. ( Khasaaraha: Halabuurka wareegga darawalka oo dhan waa mid dhib badan, qiimaha qalabku waa sarreeyaa, mugga ayaa aad u badan, kuma habboona tirada badan ee wareegyada LED. Saddexaad, qaabka isku-dhafka ah ee isku-dhafka ah ayaa la soo jeediyay iyadoo la isku darayo faa'iidooyinka ay kala leeyihiin qaababka taxanaha ah iyo kuwa isbarbar socda. Foomamka ugu muhiimsan waa labada soo socda. 1. Marka foomamka isku dhafan ee isku dhafan ay yihiin marka hore, marka tirada codsiyada LED ay weyn yihiin, taxane fudud ama isku xirnaanta isbarbardhigga waa mid aan macquul ahayn, sababtoo ah kii hore wuxuu u baahan yahay darawalka inuu soo saaro koronto sare (N times of hal volt LED VF), iyo kan dambe. waxay u baahan tahay darawalku inuu u baahdo darawalka Soo saarida qulqulka weyn (N times of hal LED current if). Tani waxay dhibaato ku keenaysaa naqshadaynta iyo samaynta darawalka, sidoo kale waxay ku lug leedahay dhibaatooyinka qaabdhismeedka iyo guud ahaan waxtarka wareegga wadista. Korontada tirada LED-yada ee taxanaha ah iyo korantada shaqada ee hal LED VF ayaa go'aamisa tamarta wax soo saarka ee aaladda wadista; Qiimaha ayaa go'aamiya awoodda wax soo saarka darawalka. Sidaa darteed, habka isku dhafka ka dib marka la isku daro inta badan waa in la hubiyo in ay jirto wax la isku halleyn karo (khaladka LED-ka ee xadhig kasta wuxuu saameeyaa iftiinka caadiga ah ee xadhigga), iyo isbarbardhigga wareegga wadista ), Waxay hagaajinaysaa kalsoonida marka loo eego foomamka taxanaha fudud. . WeChat xisaabta dadweynaha: Shenzhen LED Chamber of Commerce (wareeg dhan ayaa leh sifooyinka qaab-dhismeedka fudud, isku xirka habboon, hufnaan sare, iwm, ku habboon codsiyada leh tiro badan oo LEDs. ) 2. Dhowr LEDs ah oo lagu qaso xadhig marka hore, iyo qaababka isku dhafan ee isku dhafka ah ee isku dhafka ah ee ka horreeya xadhigga. Maaddaama LED1-N LEDM-N ay marka hore ku xiran tahay isku xirka, taas oo hagaajinaysa kalsoonida koox kasta oo LEDs ah, laakiin tani waa muhiim. Sababtan awgeed, waxaad dooran kartaa korantada shaqada iyo hadda inta ugu badan ee suurtogalka ah sida koox isku mid ah adoo isku xiraya, ama si aad u xalliso caabbinta yar ee hadda jirta ee LED kasta. (Sifada kale ee qaabkan isku dhafan ee isku dhafan iyo dhibaatooyinka jira waa isku mid. ) Afaraad, qaababka iskutallaabta ee iskutallaabta iskutallaabta ah ayaa inta badan ah si loo hagaajiyo isku halaynta shaqada LED-ka iyo in la yareeyo heerka guul-darrida. Qaabka ugu muhiimsan ee ka kooban yahay waa: taxane kasta oo 3 LEDs koox ahaan, iyo VA, VB, iyo VC wax soo saarka terminal kuwaas oo ku xiran wax soo saarka drive ee drive. Marka 3 LEDs ee taxane ah ay caadi yihiin, 3 LEDs ayaa dhalaalaya isku mar; marka hal ama laba LEDs ay xumaadaan, waxay hubin kartaa in ugu yaraan hal LED uu si caadi ah u shaqeeyo. Sidan, waxay si weyn u wanaajin kartaa isku halaynta koox kasta oo iftiinka LD ah, waxayna hagaajin kartaa isku halaynta guud ee iftiinka LED-ga oo dhan. Soo koobid: Foomamka isku xirka kala duwan ayaa leh astaamo u gaar ah, shuruudaha darawalkuna way kala duwan yihiin, gaar ahaan marka hal LED uu ku guuldareysto inuu ku guuldareysto shaqada wareegga, isku hallaynta iftiinka guud, awoodda lagu hubinayo LED-ga guud ee suurtogalka ah, awood u leh in ay sii wadato shaqada sida ugu badan ee suurtogalka ah, awoodda ay ku sii wadi karto shaqada, Waxaa si gaar ah muhiim u ah in la yareeyo waxtarka guud ee LED-ga, iwm. Dhammaan, codsiyada kooxda LED waa hab muhiim u ah codsiyada dhabta ah ee LED. Xidhiidhada LEDs ee kala duwan ayaa lagama maarmaan u ah LED-yada baaxadda leh iyo shuruudaha naqshadaynta wareegyada wadista. Sidaa darteed, marka la isku daro wareegyada dhabta ah, xulashada saxda ah ee habka isku xirka LED-ga ee ku habboon ayaa ah mid muhiim u ah hagaajinta saameynta saameynteeda iftiinka, kalsoonida shaqada, ku habboonaanta naqshadeynta darawalka iyo wax soo saarka, iyo hufnaanta wareegga oo dhan.
