Qeexida aasaasiga ah ee Bixinta Korontada Darawalka LED
Korontadu waa qalab ama qalab u beddela awoodda korantada aasaasiga ah iyada oo loo marayo farsamooyinka u beddelashada awoodda korantada ee loo baahan yahay qalabka korontada. Tamarta korantada ee aynu sida caadiga ah u isticmaalno nolol maalmeedkeena waxa ay ugu horayn ka timaadaa tamar koronto oo beddeshay, tamarta kulaylka, tamarta kiimikada, iwm. Caadi ahaan, tamarta korantada aasaasiga ah ma buuxinayso shuruudaha isticmaalaha. Tani waa halka ay korontadu ka soo gasho ciyaarta, u beddeleysa tamarta korantada aasaasiga ah tamarta koronto ee gaarka ah ee loo baahan yahay.
Qeexid: Korontada darawalka LED waa nooc ka mid ah sahay koronto oo u beddela tamarta korantada aasaasiga ah ilaha dibadda una beddelo tamarta korantada ee labaad ee loo baahan yahay LEDs. Waa unug koronto oo u beddela sahayda koronto gaar ah iyo hadda si ay u kaxeyso qiiqa iftiinka LED. Tamarta wax gelinta ee sahayda korantada darawalka LED waxaa ka mid ah AC iyo DC labadaba, halka tamarta wax soo saarka guud ahaan ay ilaaliso socodka joogtada ah ee kala duwanaan kara korontada isbeddelada korantada hore ee LED. Qaybaheeda asaasiga ah waxaa ka mid ah qalabka shaandhaynta gelinta, kontaroolayaasha beddelka, inductors, tuubooyinka beddelka MOS, iska caabiyeyaasha jawaab-celinta, qalabka shaandhaynta, iwm.
Qaybaha kala duwan ee Alaabta Korontada Darawalka LED
Qalabka korontada ee darawalka LED waxaa loo kala saari karaa siyaabo kala duwan. Caadi ahaan, waxaa loo qaybin karaa saddex nooc oo waaweyn: beddel ilo joogto ah, sahayda korantada ee tooska ah ee IC, iyo hoos u dhigista awoodda iska caabinta. Intaa waxaa dheer, oo ku saleysan qiimeynta korantada, sahayda korantada darawalka LED waxay sii kala saari kartaa awoodda sare, awoodda dhexdhexaadka ah, iyo sahayda darawalnimada. Marka la eego hababka wadista, sahayda korantada darawalka LED waxay noqon kartaa nooc koronto joogto ah ama joogto ah. Iyada oo ku saleysan qaab dhismeedka wareegga, sahayda korantada darawalka LED waxaa loo kala saari karaa sida dhimista awoodda, dhimista beddelka, dhimista iska caabinta, dhimista RCC, iyo noocyada xakamaynta PWM.
Iibka Awoodda Darawalka LED-Qaybaha Muhiimka ah ee Qalabka Iftiinka
Sida qayb lama huraan ah oo ka mid ah qalabka nalalka LED-ka, sahayda korantada darawalka LED waxay xisaabineysaa 20% -40% qiimaha guud ee qalabka LED-ka, gaar ahaan kuwa dhexdhexaadka ah iyo kuwa awoodda sare leh. Nalalka LED-ku waxay u isticmaalaan chips semiconductor sida walxo iftiin leh waxayna leeyihiin faa'iidooyin sida waxtarka tamarta, saaxiibtinimada deegaanka, samaynta midab wanaagsan, iyo waqtiga jawaabta degdega ah. Sida nooca caadiga ah loo isticmaalo ee qalabka nalka ee bulshada casriga ah, hababka wax soo saarka nalalka LED waxay ku lug leeyihiin 13 tillaabo muhiim ah, oo ay ku jiraan goynta silig, iibinta chips LED, samaynta looxyada laambada, tijaabinta looxyada laambada, codsanaya silikoon conductive kulaylka, iwm. tallaabo kasta oo wax soo saarka ayaa dalbanaya. heerarka tayada adag.
Saamaynta qotodheer ee Alaabta Korontada Darawalka LED ee Warshadaha Iftiinka LED
Sahayda korantada darawalka LED waxay la socotaa ilaha iftiinka LED iyo guriyeynta si ay u sameeyaan alaabta iftiinka LED, oo u adeegaya sida qaybahooda asaasiga ah. Caadi ahaan, nal kasta oo LED wuxuu u baahan yahay sahay koronto oo darawalka LED ah. Hawsha aasaasiga ah ee sahayda korantada darawalka LED waa in loo beddelo korantada dibadda ee danab gaar ah iyo hadda si loo kaxeeyo alaabta iftiinka LED si loo iftiimiyo iyo xakamaynta u dhiganta. Waxay door muhiim ah ka ciyaaraan kor u qaadista waxtarka, xasiloonida, isku halaynta, iyo cimriga alaabta iftiinka LED, si qoto dheer u saameeya waxqabadkooda iyo tayada. Marka loo eego tirokoobyada inta badan warshadeeyayaasha nalalka waddooyinka, ku dhawaad 90% guuldarrooyinka ku yimaadda nalalka LED-yada iyo nalalka tunnel-ka waxaa loo aaneynayaa cilladaha sahayda korontadda darawalnimada iyo isku halayn la'aanta. Markaa, sahayda korantada darawalka LED waxay ka dhigan tahay mid ka mid ah qodobbada muhiimka ah ee saameeya horumarinta warshadaha iftiinka LED.
Nalalka LED waxay si qoto dheer ula jaanqaadaan isbeddelka horumarka cagaaran
LED-yadu waxay ku faanaan wax qabad aad u wanaagsan, rajooyinkooda mustaqbalka fogna waa kuwo rajo leh. Sanadihii ugu dambeeyay, iyadoo dhibaatada cimiladu ay sii kordhayso, wacyiga deegaanka ee bulshada ayaa sii kordhayay. Dhaqaalaha kaarboon-ku-hooseeya wuxuu noqday heshiis la isku raacsan yahay horumarka bulshada. Qaybta iftiinka, wadamada adduunka oo dhan waxay si firfircoon u sahamiyaan badeecado iyo habab waxtar leh si loo gaaro ilaalinta tamarta iyo dhimista qiiqa. Marka la barbardhigo ilaha kale ee iftiinka sida nalalka iftiinka iyo halogen, nalalka LED waa il cagaaran oo leh faa'iidooyin sida waxtarka tamarta, saaxiibtinimada deegaanka, cimriga dheer, jawaab celinta degdega ah, iyo nadiifnimada midabka sare. Mustaqbalka fog, nalalka LED waxay si qoto dheer ula jaan qaadayaan isbeddelka xilliga horumarka cagaaran iyo fikradda horumar waara, oo diyaar u ah inay sugaan boos waara ee suuqa iftiinka cagaaran iyo caafimaadka leh.
Soo-Bixinta Siyaasadaha Wershadaha ee Kobcinaya Horumarka Mustaqbalka Dheer ee Warshadaha Darawaliinta
Marka la eego siyaasadaha xoojinaya qaybta, beddelka nalka LED waa fursad. Iyada oo ay ugu wacan tahay waxtarkeeda sare iyo sifooyinka tamarta-badbaadinta, iftiinka LED wuxuu u adeegaa sidii beddelka ugu wanaagsan ee ilaha tamarta sare ee dhaqanka ah. Xagga dambe ee arrimaha deegaanka ee sii kordhaya, waddamada adduunka oo dhan ayaa si isa soo taraya diiradda u saaraya ilaalinta tamarta iyo dhimista qiiqa, iyagoo si joogto ah u siidaaya siyaasadaha la xidhiidha iftiinka cagaaran. Warshadaha LED-ka ayaa noqday mid ka mid ah warshadaha istiraatiijiga ah ee dalkeena. Sahayda korantada darawalka LED-ka ayaa la filayaa inay si weyn uga faa'iidaysato taageerada siyaasadda, taasoo keenaysa weji cusub oo korriin ah. Soo-bandhigista siyaasadaha warshadaha waxay siinaya dammaanad horumarinta mustaqbalka fog ee sahayda korantada darawalka LED.
