Yintoni umahluko phakathi kwe-LED ephezulu-amandla kunye namandla amancinci?

Amandla omnye wokukhanya kwe-LED aphezulu aphezulu, ukuqaqamba kuqaqambile, kwaye ixabiso liphezulu. Umlinganiselo wangoku wamandla amancinci we-LED izibane ze-20mA, kwaye i-current rated current ingabalwa njengamandla aphezulu kunye ne-current rated over than 20mA. Inombolo yamandla ngokubanzi: 0.25W, 0.5W, 1W, 3W, 5W, 8W, 10W, njl. Iyunithi enkulu yokukhanya yi-LM (lumen), kunye neyunithi yokukhanya kwamandla amancinci ngokubanzi i-MCD. Ezi yunithi zimbini azinakuguqulwa. Okwangoku, njengohlaza olusakhulayo, ukhuseleko lokusingqongileyo, umthombo wokukhanya wokonga amandla usetyenziswa kakhulu kwizibane zemoto, iitotshi, izibane kunye nezinye iindawo. Isizathu sokuba izibane eziphezulu ze-LED zibizwa ngokuba zezi zikhanyiso ezincinci ze-LED. Kukho iintlobo ezintathu zemigangatho yokuhlela: eyokuqala kufuneka yahlulwe ibe yi-0.5W, 1W, 3W, 5W, 10W. .100W ihluke, ngokwamandla onke emveliso yokubumba emva kokupakishwa. Uhlobo lwesibini lunokwahlulwa lube: ubungakanani obukhulu be-epoxy resin packaging, ukulinganisa i-mermaid epoxy resin packaging, ukupakishwa kwe-aluminium, i-aluminiyam, i-aluminiyam, kunye ne-aluminiyam. Uhlobo lwesithathu lwe-substrate (MCPCB) encapsulation, Ukupakisha, amandla-uhlobo lwephakheji ye-SMD, iphakheji edibeneyo ye-MCPCB, njl. Uhlobo lwesithathu lunokwahlulwa lube yimveliso yamandla eguga ephantsi kunye nemveliso yamandla egugayo engekho phantsi-phantsi ngokweqondo layo lokuguga kokukhanya. Kakade ke, ngenxa yokuba zininzi iiparameters ze-high-power LED ukukhanya ngokwayo, kuya kubakho imigangatho yokuhlela eyahlukeneyo ngokweeparamitha ezahlukeneyo. Izibane eziphezulu ze-LED zisezenye yeemveliso zokupakisha ze-LED, eyona nxalenye ibalulekileyo yokukhanya kwe-semiconductor ukuya kwindawo yokukhanya okuqhelekileyo. Xa usebenzisa izibane ze-LED eziphezulu, kufuneka uqonde ukuhanjiswa kokukhanya kokusabalalisa ukukhanya, ukusabalalisa ubushushu bombala, ukuxhathisa kwe-thermal kunye nokunikezelwa kombala ukuze uphumelele imephu yokusabalalisa ukukhanya kwe-W -class high -power LED ukukhanya. Kuyimfuneko ukusebenzisa ngokuchanekileyo ukukhanya kwe-LED yamandla aphezulu. Abavelisi kufuneka banikeze abathengi ngezibonakaliso ezahlukeneyo zeparameter yezixhobo ze-LED nokuba ukuhanjiswa kokushisa kombala kwezibane ze-LED eziphezulu zisasazwa ngokulinganayo, eziza kuchaphazela ngokuthe ngqo umphumo wokukhanyisa; kunye nobushushu bombala kunye nesalathiso sombala sonikezelo ziqhakamshelene, kwaye utshintsho lobushushu bombala luya kubangela utshintsho kwisalathiso sombala wonikezelo. Ukumelana ne-thermal yokukhanya kwe-LED ephezulu kuchaphazela ngokuthe ngqo ukutshatyalaliswa kobushushu bezixhobo ze-LED. Ukuchasana kwe-thermal ephantsi, ngcono ukutshatyalaliswa kobushushu; ukumelana nobushushu kubi, ukuze ubushushu besixhobo bunyuke, nto leyo eya kuchaphazela ukukhukuliseka kwamaza okukhanya. Ngokwamava, iqondo lobushushu liyenyuka kube kanye, kwaye ubude bokukhanya kufuneka bukhukuliseke nge-0.2 0.3nm, nto leyo eya kuthi ichaphazele ngokuthe ngqo umgangatho oqaqambileyo wesixhobo. Ukunyuka kokushisa okugqithisileyo kuchaphazela ngqo ubomi benkonzo ye-W -level high -power LED isibane sokugcina amandla. Umbala luphawu olubalulekileyo lokukhanya okumhlophe kwe-LED. Umbala wokukhanya okumhlophe kwe-LED yokukhanyisa kufuneka ube ngaphezu kwe-80 okanye ngaphezulu.
