Yintoni isibane se-LED Strip?
Izibane ze-LED zintsha kunye neendlela eziguquguqukayo zokukhanyisa. Kukho iinguqulelo ezininzi kunye nezingaphandle, kodwa ubukhulu becala, zineempawu ezilandelayo:
● Ziquka ii-emitters ezininzi ze-LED ezifakwe kwibhodi yesekethe emxinwa, eguquguqukayo
● Sebenza kumbane we-DC ophantsi-voltage
● Zifumaneka kuluhlu olubanzi olusisigxina kunye nombala oguquguqukayo kunye nokukhanya
● Inqanawa ekwireel ende (ngokuqhelekileyo i-16 feet / 5 metres), inokusikwa ibe yinde, kwaye iquka ukuncamatheliswa kwamacala amabini ukuze kuxhonywe.
I-Anatomy yomgca we-LED
Ukukhanya komcu we-LED kuqhelekile ukuba sisiqingatha se-intshi (10-12 mm) ububanzi, kwaye ukuya kuthi ga kwi-16 iinyawo (5 yeemitha) okanye ngaphezulu ubude. Banokunqunyulwa kubude obuthile besebenzisa isikere nje ecaleni kwendlela, ebekwe yonke i-intshi eyi-1-2.
Ii-LED zomntu ngamnye zixhonywe ecaleni komcu, ngokuqhelekileyo kuxinaniso lwe-18-36 LEDs ngenyawo (60-120 ngemitha). Umbala okhanyayo kunye nomgangatho wee-LED zomntu ngamnye umisela umbala wokukhanya ngokubanzi kunye nomgangatho we-strip ye-LED.
Icala elingasemva lomtya we-LED ubandakanya i-adhesive efakwe ngaphambili kabini. Sula ngokulula i-liner, kwaye unyuse umtya we-LED kuwo nawuphi na umphezulu. Ngenxa yokuba ibhodi yesekethe yenzelwe ukuba ibe bhetyebhetye, imichilo ye-LED inokufakwa kwiindawo ezigobileyo nezingalinganiyo.
Ukumisela ukukhanya kwe-LED Strip
Ukukhanya kwemichilo ye-LED kuchongwa ngokusebenzisa i-metriclumens. Ngokungafaniyo ne-incandescent bulbs, ii-strip ze-LED ezahlukeneyo zinokuba namanqanaba ahlukeneyo okusebenza, ngoko ke ukulinganiswa kwamanzi akusoloko kunentsingiselo ekumiseleni ukukhanya kokwenene.
Ukukhanya komcu we-LED ngokuqhelekileyo kuchazwa kwiilumens ngenyawo (okanye imitha). Umcu we-LED womgangatho olungileyo kufuneka unike ubuncinci i-450 lumens ngenyawo (1500 lumens ngemitha nganye), ebonelela malunga nomlinganiselo ofanayo wokukhanya ophumayo ngenyawo njengesibane esiqhelekileyo seT8 fluorescent. (Umzekelo 4-ft T8 fluorescent = 4-ft of LED strip = 1800 lumens).
Ukukhanya komcu we-LED kumiselwa ikakhulu ngezinto ezintathu:
● Ukukhanya okukhanyayo kunye nokusebenza kakuhle kwi-emitter ye-LED nganye
● Inani le-LED ngenyawo
● Umzobo wamandla wentambo ye-LED ngenyawo nganye
Isibane somcu we-LED ngaphandle kokucaciswa kokukhanya kwi-lumens yiflegi ebomvu. Uyakufuna kwakhona ukujonga ixabiso eliphantsi leentambo ze-LED ezibanga ukuqaqamba okuphezulu, njengoko zinokuqhuba ngaphezulu ii-LED ukuya kwinqanaba lokusilela kwangaphambi kwexesha.
Uxinaniso lwe-LED kunye noMzobo waMandla
Unokudibana namagama ahlukeneyo emitter ye-LED njenge-2835, 3528, 5050 okanye 5730. Musa ukuxhalaba kakhulu malunga nale nto, njengoko eyona nto ibaluleke kakhulu kwi-strip ye-LED yinani le-LED ngenyawo, kunye nokutsala amandla ngonyawo ngalunye.
Ubuninzi be-LED bubalulekile ekunqumeni umgama phakathi kwe-LED (i-pitch) kunye nokuba kuya kubakho iindawo ezibonakalayo ezibonakalayo kunye neendawo ezimnyama phakathi kwee-emitters ze-LED. Uxinzelelo oluphezulu lwee-LED ezingama-36 ngenyawo (ii-LED ezili-120 ngemitha nganye) ziya kubonelela ngeyona nto ingcono, isiphumo sokukhanya esisasazwe ngokulinganayo. I-LED emitters lelona candelo libiza kakhulu kwi-LED strip yokwenziwa, ke qiniseka ukuba ujonga umahluko phakathi koxinzelelo lwe-LED xa uthelekisa amaxabiso e-LED strip.
Okulandelayo, qwalasela umzobo wamandla wesibane sesibane se-LED ngenyawo nganye. Ukutsalwa kombane kusixelela ubungakanani bamandla eza kusetyenziswa yinkqubo, ngoko ke oku kubalulekile ukumisela iindleko zakho zombane kunye neemfuno zobonelelo lwamandla (jonga ngezantsi). I-strip ye-LED esemgangathweni kufuneka ikwazi ukubonelela ngeewathi ezi-4 ngenyawo okanye ngaphezulu (15 W / imitha).
Okokugqibela, jonga ngokukhawuleza ukufumanisa ukuba ii-LED zomntu ngamnye ziqhutywa ngokugqithisileyo ngokwahlula amanzi ngonyawo ngalunye ngoxinaniso lwe-LED ngenyawo. Kwimveliso ye-LED strip, idla ngokuba luphawu oluhle ukuba ii-LED aziqhutywa ngaphezu kwe-0.2 watts nganye.
Izinketho zoMbala we-LED Strip: Mhlophe
Izibane ze-LED strip ziyafumaneka kwimibala eyahlukeneyo emhlophe okanye imibala. Ngokubanzi, ukukhanya okumhlophe lolona khetho luluncedo kwaye ludumileyo kwizicelo zokukhanyisa ngaphakathi.
Ekuchazeni i-shades eyahlukeneyo kunye neempawu ezimhlophe, ukushisa kombala (CCT) kunye nesalathisi sombala (CRI) zimbini iimetriki ezibalulekileyo ukuba zigcinwe engqondweni.
Ubushushu bombala ngumlinganiselo wendlela "ukufudumala" okanye "kupholile" umbala wokukhanya ubonakala ngayo. Ukukhanya okuthambileyo kwebhalbhu yesiqhelo ekhanyayo inobushushu obuphantsi bombala (2700K), ngelixa i-crisp, emhlophe eqaqambileyo yemini yendalo inobushushu obuphezulu bombala (6500K).
Ukwenziwa kombala ngumlinganiselo wendlela imibala echanileyo ebonakala ngayo phantsi komthombo wokukhanya. Ngaphantsi komgca we-LED ophantsi we-CRI, imibala inokuvela igqwethiwe, ihlanjwe, okanye ingabonakali. Iimveliso ze-LED eziphezulu ze-CRI zibonelela ngokukhanya okuvumela izinto ukuba zibonakale ngendlela ezinokuthi zibonakale ngayo phantsi komthombo wokukhanya ofanelekileyo njengesibane se-halogen, okanye ukukhanya kwemini yendalo. Khangela kwakhona ixabiso le-R9 lomthombo wokukhanya, elibonelela ngolwazi olungakumbi malunga nendlela imibala ebomvu eyenziwa ngayo.
Izinketho zoMbala we-strip ye-LED: Umbala osisigxina kunye noGuquguqukayo
Ngamanye amaxesha, unokufuna i-punchy, umbala ogcweleyo. Kwezi meko, imichilo ye-LED enemibala inokunika i-accent enkulu kunye neziphumo zokukhanya kwethiyetha. Imibala kuyo yonke i-spectrum ebonakalayo iyafumaneka-i-violet, ibhlowu, eluhlaza, i-amber, ebomvu-kunye ne-ultraviolet okanye i-infrared.
Kukho iintlobo ezimbini eziphambili zomtya we-LED onemibala: umbala omnye osisigxina, kunye nokutshintsha umbala. Umbala osisigxina we-LED strip ukhupha umbala omnye, kwaye umgaqo wokusebenza ufana nje nemicu ye-LED emhlophe esixubushe ngayo ngasentla. I-strip ye-LED etshintsha umbala iqulathe amajelo anemibala emininzi kumtya we-LED omnye. Olona hlobo lusisiseko luya kubandakanya iitshaneli ezibomvu, eziluhlaza kunye nebhlowu (RGB), ekuvumela ukuba udibanise ngokuguquguqukayo amacandelo ombala ohlukeneyo kwimpukane ukufezekisa phantse nawuphi na umbala.
Abanye baya kuvumela ulawulo oluguqukayo lokutshintsha kobushushu bombala omhlophe okanye zombini ubushushu bombala kunye nemibala ye-RGB.
Igalelo lombane kunye noBonelelo lwaMandla
Uninzi lwemicu ye-LED ilungiselelwe ukuba isebenze kwi-12V okanye i-24V DC. Xa ucima umthombo oqhelekileyo wobonelelo lombane oyintloko (umz. indawo yokuphuma eludongeni lwendlu) kwi-120/240V AC, umbane kufuneka uguqulelwe kumqondiso ofanelekileyo wombane ophantsi we-DC. Oku kwenzeka rhoqo kwaye kufezekiswa ngokulula kusetyenziswa unikezelo lombane lweDC.
Qinisekisa ukuba umbane wakho waneleumthamo wamandlaukunika amandla imichilo ye-LED. Unikezelo lwamandla ngalunye lwe-DC luya kudwelisa ubuninzi balo bangoku (kwi-Amps) okanye amandla (kwi-Watts). Qinisekisa umzobo wamandla ewonke wentambo ye-LED usebenzisa le fomula ilandelayo:
● Amandla = Amandla e-LED (ngeft) x ubude bomgca we-LED (nge-ft)
Umzekelo wemeko yokudibanisa i-5 ft yomgca we-LED apho ukusetyenziswa kwamandla komcu we-LED ziiWatts ezi-4 ngenyawo:
● Amandla = 4 Watts ngeft x 5 ft =20 Watts
Umzobo wamandla ngenyawo nganye (okanye imitha) uphantse wasoloko udweliswe kuluhlu lwedatha ye-LED.
Awuqinisekanga ukuba kufuneka ukhethe phakathi kwe-12V kunye ne-24V? Yonke enye into iyalingana, i-24V yeyona nto ingcono yokubheja kwakho.
