Eziluzizi ngokuba strip LED kunye elawulwa-kude

imicu LED kuyanda kusetyenziswa kuyilo bezinto ezahlukeneyo, zombini ngaphakathi nangaphandle kwezakhiwo. Zinceda ukwenza zombini izibane buso kunye jikelele, sigxininise iinxalenye iyingenelo. Umdibaniso indlela ekhethekileyo. Ukuze wenze oku, sebenzisa nokuvula umbane eziluzizi ukuba zephetshana LED. Ulawula ngobunzulu ukukhanya kwaye enxulumene ekhaya. Ukuze entabeni ekhasethini oku, kufuneka uwazi ukufakela ubuchwepheshe kule nkqubela iintambo.

Control Iimpawu tape LED

Ukuze siqonde ukubeka indlela umbane eziluzizi ukuya iribhoni LED kufuneka babenolwazi kunye nomgaqo nkqubo. strip LED i semiconductor, kwaye inani iimpawu ezithile. Omnye wabo eziphatha njenge non-linear iimpawu zangoku-ombane ebalulekileyo (CVC). Yangoku ayahamba na iribhoni lukhula kakhulu ngamandla, ukuqala kwindawo embundwini ethile. Oku kunokubangela umzali kwefowuni izibane. Nokuba a encinane ngedrophu ombane kuso tape inokuba nokuba yonakele. Ngoko ke, lo uqhagamshelo kwinethiwekhi awukwazi ukwenziwa ngqo. Eziluzizi for strip LED - enye yezisombululo ezinokusebenza kule ngxaki.

Zizixhobo circuit yolawulo ngokuyimfuneko kubandakanya okulinganisela umbane, iyenza oluzinzileyo efanelekileyo ngokunokuba ukudibanisa i sixhobo. Ngamanye amaxesha ezi njongo basebenzisa resistors amandla. Kodwa ke kule meko iya kulahleka ukuba kungachitha igunya enkulu yombane. Ukuze le nkqubo isebenze kakuhle, kufuneka usebenzise amandla ombane aphantsi ngoku rhoqo, nto leyo nokuvula umbane eziluzizi xa zephetshana LED ngezandla zakho.

Umgaqo esebenza ngayo umbane eziluzizi

Eziluzizi for imicu LED eyenziweyo njengoko imodyuli eyahlukileyo 12 ombane igalelo, 24 volts. Ine- output limiter yangoku. Ukuze ukhethe icebo ulawulo ekunene, kuyimfuneko ukuba masihambelane kunye tape iinketho. Kufuneka ube ombane efanelekileyo igalelo. Utyando ngokupheleleyo LED ukubonelela ngelo resistors efanayo ixesha umda. ngokokwakheka Bona zixhonywe tape ngokwayo. Amandla unit yolawulo kunye namandla liyangqinelana nokuvula umbane eziluzizi kwinani LED EzisembindiniName tape.

Abavelisi benza izixhobo zokukhanyisa enjalo obude ethile, ongowona ngaphantsi kwe m-5. Ukuba kuyimfuneko, i-tape kukuncwina kokuyisika kwiindawo ezithile. Kodwa kwimeko imfuneko yokwandiswa intwana yayo elandelayo ongadibenanga ngokunxuseneyo, yaye ukuya unikezelo lwamandla ahambelanayo okanye umsindo. Eziluzizi kwakhona ikuvumela ukuba angegqithi kuphela nangaphandle izibane, kodwa kwakhona ukulawula ukukhanya kukona yayo.

Iintlobo indlela yolawulo dimmers

Ngaphandle kokuba ayahluka isixhobo yolawulo lwamandla (Kukhona nokuvula umbane eziluzizi kuba LED osisingela volts 12 volts 24), zahluke kunye nendlela yolawulo. Bona ntlobo zilandelayo:

• esinolawulo isikrini kude;
• esinolawulo push iqhosha-kude;
• ngaphandle ukulawula;
• ukuchukumisa ulawulo eveze;
• Kulungiselelwa Wi-Fi yefowuni.

Ukuze khetha inkqubo yolawulo ekunene, kufuneka ucinge uhlobo umbane eziluzizi, kwizikolo ezikude yayo evela kude (kuyimfuneko ukubala umgama ukusuka kwindawo yolawulo ukuze ulungise ukukhanya ifowuni). Kwakhona unalo ixabiso inani izixhobo ukuba ngaphakathi uluhlu okukude. Kukho imizekelo apho kunokwenzeka ukudibanisa ukuya dimmers-10. Ubukhulu console nazo ngamanye amaxesha badlala indima ebalulekileyo. Mini eziluzizi for strip LED rhoqo yeyona elula zonke iintlobo uhlengahlengiso.

Kuxhomekeka ukhetha ukukhetha umgangatho intuthuzelo kwebala, ulawulo push iqhosha-okanye izixhobo eziphathekayo.

features zolawulo

Eziluzizi ngaphandle ulawulo kulawulwa ngendlela efakwe kwi istili. Le yenye yeendlela ilula zokulawula. Inokuba i mini-dimmers, okusetyenziselwa zephetshana LED. Zibonakala ngathi eyenziwayo ezincinane.

Eziluzizi nge elawulwa kude for zephetshana LED ikuvumela ukulawula njengokukhazimla mveliso mgama. Le yindlela elula, ingakumbi kwimeko lokufumana i tape phezulu eluphahleni, phezu Inqwanqwa, njalo-njalo. D.

Ukuba uyilo isilawuli uyonyulwa ukuze balungele isimbo ophezulu zobugcisa, okanye imbonakalo yalo nomtsalane ngakumbi zomsebenzisi, bafumana touchpads ingontsi. Baya ayalingana ubungakanani utshintsho ukukhanya. Kodwa babe uluhlu lwemisebenzi eyongezelelweyo.

Ukulawula ukukhanya mgama, usebenzisa i software eyodwa efakwe kwifowuni yakho okanye tablet. Oku kuluncedo kakhulu izinto eziqulathe inani elikhulu iiteyiphu ukuba ubude omkhulu lwefacade zokwakha, iimpawu zentengiso.

Iindidi dimmers yi indlela yolawulo ombane

Ngokulungisa indlela utshintsho ombane bahlule dimmers abalawula ezikhoyo umthwalo amandla, kunye nezinye - ngokusebenzisa ububanzi ukubetha kwezwi (PWM).

Kuyabiza kwaye isixhobo kolawulo litshintsha ombane ngapha umthwalo. Zisetyenziswa kunqabile kakhulu ngezithandelo LED, ekubeni nako ukusebenza umbane ophantsi.

Eyona lisetyenziswa kumaxesha amaninzi inkqubo dimmers esekelwe PWM. Ba compact aze enze umsebenzi wayo ngendlela eyiyo. Ekhaya, ukuphumeza ulawulo strip LED kumgaqo PWM ilula. Oku amandla kwanomntu kunye namava. Ukuze wenze oku, sebenzisa i uhlanganiso chip encinane.

Ukuthobela kunye nokuvula umbane eziluzizi uhlobo tape

Eziluzizi for imicu LED enxulumene ngokungqinelana kunye nohlobo yesixhobo. Kukho single-channel cebo uqhagamshelwano ngentambo multi-channel, leyo bahambelana imisebenzi ngokukhanyisa. Ukwenza iziphumo ezahlukeneyo Izibane kusetyenziswa dimmers emithathu nomzila-anababini.

Ukuze ilungele RGB channel-amathathu unit uhlobo lolawulo tape. Olu hlobo intambo iye LED ezintathu imibala ezahlukeneyo, xa ixutywe ukunika ukukhanya emhlophe. Ukukhanyisa multi-bala, ukuba asebenze ngokwahlukeneyo. dimmers siteshi-ezimbini esetyenziselwa ubumba phosphor. Kwezi umaleko ekhethekileyo emthubi axutywe oluhlaza eyomeleleyo LED.

Ngeeribhoni ezimhlophe-ukukhanya monocrystalline single- kusetyenziswa nabalawuli ukukhanya, ezifakwe kwisekethe emva kokuba unikezelo lombane.

Izinto eziluncedo nezingeloncedo of abalawuli PWM

Ukuze siqonde indlela ukudibanisa kwi LED umcu nokuvula umbane eziluzizi, kufuneka uziqhelanise wena kunye iimpawu regulyatorv PWM.

Ngapha koko, olu hlobo amaninzi kusetyenziswa ulawulo iintambo self-kokuxhuma.

Engxakini olu hlobo nokuvula umbane eziluzizi igqalwa yokudanyaza ngakumbi kumanqanaba ukukhanya eliphantsi. Eye kule imo ibhaqa oscillations chweba. Le isiphumo kunokubangela yintloko kunye nesimo ngokwasengqondweni komzimba, ngokonakala umbono.

Ukuze siphephe le ngxaki, kufuneka usebenzise inkqubo ekhethekileyo microcontrollers. Zisebenza analog-to-digital mode.

Ukufakelwa umbane eziluzizi ekhaya

To ngokufanelekileyo ukudibanisa i nokuvula umbane eziluzizi ukuba zephetshana LED kunye izandla zenu, sebenzisa ibhodi yesekethe eziprintiweyo, nto leyo yenziwa fiberglass nge alumuniyam eliqinileyo. It has a ubukhulu 35x50 mm.

Ekuqaleni beka isinxibelelanisi ngenxa iziphaluka angaphandle, kunye resistors. Emva koko, lo uhlelo ode, capacitors, chip apha. Ekupheleni kwale nkqubo kufuneka soldered FET. Emva koko, qiniseka ukuba asuse Oxhumayo, leyo kwi iiterminal transistor. Kungenjalo, inkqubo yonke alitshise ngoko nangoko emva amandla-up!

Eziluzizi ise kwityala yeplastiki okhethekileyo. Ukulungiselela le njongo, isitya isepha ezifanelekileyo, apho imigodi eweva ngenxa intambo kunye resistor elitshintshayo.

isicelo

Abizelwa nokuvula umbane eziluzizi ngenxa strip LED ingasetyenziselwa iinjongo ezininzi. Yena ifanele kakuhle ukuba ulungise ukukhanya intambo, nto leyo ibekwe kwindawo yokusebenza-workshop, ikhitshi okanye ezinye izakhiwo. Kuyinto nje kuyimfuneko emva ukusetyenziswa ixesha elide. Emva ukukhanya okuqaqambileyo zenzi amehlo akho yaye ekugqibeleni zibulale umbono.

Xa izibane likaxakeka into kuxhaswa ibhetri, izidenge tape ukuvutha nga ngokubonakalayo ukwandisa ixesha le generator.

Kuba RGB-tapes ezenziwe isixhobo ezintathu ezahlukeneyo ulawulo. Oku kuya kudala naliphi umthunzi ukunika into image yokuqala. Iza kuthatha indawo, umzekelo, ukuze ndibutshitshise esisebenza endala.

Emva isixhobo kokufunda ezifana nokuvula umbane eziluzizi ngenxa LED strip, ungenza ngokulula bahlanganisane ngayo ekhaya. Ngokusekelwe iingcebiso ezidweliswe nqaku, ukudala iziphumo zokukhanyisa ekhethekileyo nayiphi na into okanye ngaphakathi kwisakhiwo kuya kuba lula.
