(一) Dulmarka horumarka iftiinka hoose ee LED
Komishanka Qaranka ee Horumarinta iyo Dib-u-habaynta Shiinaha ayaa soo saaray "Roadmap-ka loogu talagalay joojinta laambada shida ee Shiinaha", kaas oo dhigaya in laga bilaabo Oktoobar 1, 2012, soo dejinta iyo iibinta nalalka 100 watts iyo wixii ka sarreeya nalka guud la mamnuuci doono. Laga bilaabo Oktoobar 1, 2014, soo dejinta iyo iibinta 60 watts iyo wixii ka sareeya nalalka guud waa mamnuuc. Waxaa la filayaa in laga bilaabo Oktoobar 1, 2016, soo dejinta iyo iibinta 15 watts iyo wixii ka sareeya nalalka guud ee nalka la mamnuuci doono, taas oo ka dhigan in gebi ahaanba la soo afjaray nalalka guud ee nalalka Shiinaha. Iyada oo si tartiib tartiib ah ay u luminayaan nalalka iftiinka, nalalka horseedka ah sida xoogga cusub ee badbaadinta tamarta iyo ilaalinta deegaanka ayaa si tartiib tartiib ah u soo ifbaxday oo ay dadku yaqaaneen.
Marka la eego qiimaha kor u kaca ee budada fluorescent, qiimaha nalalka caadiga ah ee tamarta tamarta ayaa sii kordhaya, iyo nalalka cusub ee LED sida qalabka nalalka ayaa si tartiib tartiib ah u soo galay goobta aragtida dadweynaha. Tan iyo dhalashadii nalalka LED-ka, dhalaalkooda si joogto ah ayaa loo wanaajiyey, si tartiib tartiib ah uga soo tusaha LED-ka oo galay goobta iftiinka LED-ka. Nalalka LED-ka ayaa si tartiib tartiib ah uga beddelaya iftiinka-dhamaadka sare ee bilowga ilaa gacaliyaha cusub ee suuqa codsiga.
Falanqaynta heerka iftiinka LED
Sannado badan oo horumarineed ka dib, nalalka LED-yada ayaa si weyn loogu isticmaalay injineernimada iyo horumarinta guriga, asal ahaan beddelaya nalalka dhaqanka. Dhinaca nalalka LED-ka, nalalka hoose ayaa la odhan karaa waa qaybta ugu caansan, sababtoo ah nuxurka farsamada ma aha mid sare, asal ahaan warshadaha muraayadaha ayaa la soo saari karaa. Ma jiro meel laga soo galo, qof kastaa wuu soo saari karaa, ku qulquli karaa, taasoo keentay tayada aan sinnayn, qiimaha u dhexeeya dhowr doolar ilaa daraasiin doolar, markaa suuqa iftiinka LED-ka ee hadda jira ayaa weli ah mid fowdo ah. Isla mar ahaantaana, qiimaha hoose ee hadda jira waa mid aad u hufan, laga bilaabo chip, qolof ilaa baakadaha iyo qalabyada kale ee kharashka iibiyaasha ayaa si cad u fahmaya, sababtoo ah caqabadda soo gelista hoose, wax soosaarayaal badan, tartan adag, sidaas darteed faa'iidada iftiinka LED marka la barbar dhigo badeecadaha kale ee ganacsiga aad uga hooseeya.
Nalalka hoose ayaa guud ahaan loo adeegsadaa xarumaha dukaameysiga, xafiisyada, warshadaha, isbitaallada iyo nalalka kale ee gudaha, rakibiddu waa mid fudud oo ku habboon dadka inay jeclaadaan. Nalalka LED-yada waxay dhaxlaan dhammaan faa'iidooyinka iftiinka dhaqameed, kulayl yar, nolosha badbaadinta tamarta dheer, iyo kharashka dayactirka ugu yar. Nalalka LED-ka ee hore sababtoo ah qiimaha sarreeya ee tusmooyinka iftiinka LED, kharashka guud ma aqbalo macaamiisha. Iyada oo la dhimay qiimaha jajabyada iftiinka LED-ka iyo hagaajinta tignoolajiyada kuleylka kuleylka, waxay aasaas adag u dhigtay nalalka LED-yada si ay u galaan goobta ganacsiga.
Nalalka LED-yada waxay ka kooban yihiin kuul LED, guri iftiin leh, iyo sahay koronto ah. Kuulyada hoose, waxay ku habboon tahay in la isticmaalo nalalka tamarta sare leh sida hal laambad oo 1W ah, waa in aan la isticmaalin awood yar sida 5050,5630 iyo nalalka kale ee nalalka, sababta ayaa ah in iftiinka iftiinka iftiinka iftiinka iftiinka uu yahay mid dhalaalaya. Ku filan laakiin iftiinka iftiinka kuma filna, iyo iftiinka LED-ka guud ahaan wuxuu iftiiminayaa masaafada toosan waa 4-5 mitir, sababtoo ah xoogga iftiinka iftiinka hooseeya kuma filna sidaas darteed xoogga iftiinka dhulka kuma filna. Qurxinta laydhka sare, gaar ahaan xoogga iftiinka iftiinka iftiinka isku-dhafan, ayaa noqday kuwa ugu horreeya ee soo saara iftiinka iftiinka LED. Waqtigan xaadirka ah, waxa sida caadiga ah loo isticmaalo waa laambad awood sare leh sida hal laambad oo 1W ah, oo laga sameeyay iftiin hoose 1W, 3W, 5W, 7W, 9W, iwm, ugu badnaan waxaa guud ahaan laga dhigi karaa 25W, haddii la isticmaalo Nidaamka isku dhafka awoodda sare wuxuu kaloo sameyn karaa awood sare.
Waxaa jira saddex qaybood oo waaweyn oo go'aamiya nolosha iftiinka hoose: laambada LED-ka, qaboojinta "naqshad qolof", iyo sahay koronto horseed u ah. Soosaarayaasha laambada LED-ka ayaa go'aamiya nolosha ugu weyn ee nalalka LED-ka, waqtigan xaadirka ah, soosaarayaasha tayada sare leh ee ajnabiga ah waxay leeyihiin US CREE, Japan Nichia (Nichia), West Iron City, iwm., soosaarayaasha Taiwan qaaliga ah Waxaa loola jeedaa iibsashada alaabada baakadaha loo yaqaan 'crystal led chip', inta badan Taiwan ama warshadaha baakadaha Cross-Strait ee Shiinaha), bilyan iftiinka, iwm.
Guud ahaan, soosaarayaasha tayada sare leh ee iftiinka iftiinka LED waxay isticmaali doonaan jajabyada CREELED ee ajnabiga ah, ugu yaraan mid ka mid ah badeecadaha aadka u xasilloon ee laga aqoonsaday suuqa. Nalalka lagu sameeyay habkan ayaa leh dhalaal dabiici ah oo sarreeya, nolol dheer, laakiin qiimihiisu maaha mid raqiis ah, iyo nolosha chip-ka ee soosaarayaasha Taiwan ayaa sidoo kale dheer, laakiin qiimuhu waa mid aad u hooseeya, taas oo asal ahaan la aqbali karo macaamiisha suuqa dhexe ee Shiinaha. . Nolosha Chine ee suuqa maxalliga ah waa mid gaaban, suuska iftiinka waa weyn yahay, laakiin qiimaha ugu hooseeya ayaa noqday doorashada koowaad ee tiro badan oo warshado yaryar ah si ay ula dagaalamaan qiimaha. Nooca nalalka LED-yada iyo chips-ka LED-ka ee loo isticmaalo ayaa sidoo kale si toos ah u go'aaminaya meelaynta soo-saarayaasha iftiinka LED-ka iyo mas'uuliyadda bulshada ee lagu soo bandhigay warshadaha.
Korontada LED-ku waa wadnaha nalalka LED-yada, taas oo saameyn weyn ku leh nolosha nalalka LED-ka. Guud ahaan, nalalka LED-ku waa koronto 110/220V, suuqa maxalliga ah ee Shiinaha waa sahay koronto oo 220V ah. Sababtoo ah wakhtiga horumarinta gaaban ee nalalka LED-ka, waddanku weli ma dejin heerarka tamarta korontada, sidaas darteed korontada LED-ka ee suuqa waa mid aan sinnayn, sawirka giraanta waa transverse, tiro badan oo ah qiimaha PF hoose, oo aan awoodin. Daadadka suuqa iyada oo loo marayo korontada EMC. Nolosha korantada korantada ee korantada ayaa sidoo kale si toos ah u go'aamisa nolosha tamarta korontada, sababtoo ah waxaan u nugulnahay qiimaha, waxaanan helnaa siyaabo lagu dhimo qiimaha tamarta korontada, taasoo keentay in beddelka awoodda hoose ee awoodda LED. sahayda, iyo nolosha adeeggu ma dheera, sidaa darteed iftiinka LED-ka ayaa laga beddelaa "laambad cimri dheer" oo loo beddelo "laambad gaaban".
Naqshadeynta kulaylka iftiinka iftiinka LED-ka ayaa sidoo kale muhiim u ah nolosheeda, kulaylka LED-ka waxaa laga soo qaadaa laambada laambada oo loo gudbiyo PCB gudaha ka dibna loo dhoofiyo guriga, ka dibna guriga waxaa loo gudbiyaa hawada iyada oo loo marayo convection ama convection. Kala-baxa kulaylka PCB waa inuu ahaado mid degdeg ah oo ku filan, waxqabadka kuleylka kuleylka ee dufanka kulaylka waa inuu ahaadaa mid ku filan, aagga kulaylka ee qolofku waa inuu ahaadaa mid weyn oo ku filan, iyo naqshadeynta macquulka ah ee dhowr arrimood ayaa go'aaminaya in heerkulka isku xirka PN uusan noqon karin. in ka badan 65 digrii marka nalka LED uu si caadi ah u shaqeeyo, si loo hubiyo in chip LED uu ku jiro heerkulka shaqada ee caadiga ah mana soo saari doono suus iftiin ah sababtoo ah heerkulku aad buu u sarreeyaa oo aad u dheereeyaa.
Hidiyeeriyaha LED wuxuu xalin karaa dhibaatooyinka la xiriira ee ay keentay awood la'aanta hiitarka inuu u dhoofiyo kulaylka tusaha laambada iyo PCB-ga gudaha: wuxuuna dalbaday shati qaran; Waxay ka samaysan tahay aluminium tayo sare leh oo 6063 ah, samaynta saamaynta kuleylka kulaylka iyo kuleylka mid ka mid ah, si loo gaaro hufnaanta kuleylka kuleylka iyo kuleylka kuleylka; Dusha sare ee hiitarka waxa loo qaabeeyey iyada oo leh godad badan oo kulaylka daadiya, iyo kulaylka ka baxsan hiitarka ayaa ah mid hagaya si loo gaadho isu-ururinta hawada. Sida tirada badan ee tuubooyinka qiiqa, kulaylka LED-ka ayaa kor loo sii daayaa, kulaylkana waxaa lagu kala daadiyaa weelka kulaylka, si loo gaaro kuleyl wax ku ool ah.
