Ii-LED zamandla aphezulu njengemithombo yokukhanyisa sele zikhona kuyo yonke indawo, kodwa ungakanani owaziyo malunga nee-LED, kwaye oku kulandelayo kuya kukuthatha ukuba ufunde ulwazi oluthile malunga nee-LED.
Iimpawu zokukhupha ukukhanya kwee-LEDs
Ngokuqhubela phambili ngokukhawuleza kwethekhnoloji ye-LED, izikhombisi zokusebenza ziphuculwe kakhulu.Ngokukodwa, ukusebenza kwee-LED ezimhlophe ezinamandla aphezulu, okuyizona zikhanyisayo zesizukulwana sesine, ziphuculwe kakhulu.Ngokweemfuno ezahlukeneyo zokusetyenziswa, amandla epakethe enye ahlukanisiwe: ukusuka kwi-1 ~ 10W ukuya kumakhulu e-watts, amakhulu e-watts;Ukususela kukukhanya kokukhanya okukhupha ukukhanya kweempawu ze-lens yepakethe ye-LED, ezona ziphambili zezi: Uhlobo lwe-Lambertian, uhlobo lokukhanya kwecala, uhlobo lwe-bat wing, uhlobo lokugxila (i-collimation) kunye nezinye iintlobo, kunye ne-curve ye-output character iboniswe kumzobo.
Okwangoku, uhlobo lwamandla olumhlophe lwe-LED luphuhla kwicala le-single-chip yamandla aphezulu, kodwa ngenxa yemiqobo yebhodlela yokuphelisa ubushushu be-chip, ukutshatyalaliswa kobushushu be-chip enye ye-ultra-large yamandla e-LED usebenzisa i-multi-chip indibaniselwano yokupakisha. Kunzima kakhulu, kwaye ukukhanya okukhanyayo kuphantsi kakhulu. Kuyilo lwezibane zesitrato ze-LED ezinamandla aphezulu, ukukhethwa kwee-LED eziphezulu kufuneka kuthathelwe ingqalelo imiba emininzi efana neempawu zokupakisha eziphambili, ukukhanya okukhanyayo, iimfuno zenkqubo yokufakela, isibini kunye uyilo lokusasazwa kokukhanya okuphezulu, indawo yokusetyenziswa, iimeko zokulahla ubushushu, kunye neempawu zemveliso zomlawuli wokuqhuba.Ke ngoko, kudityaniswe nezi zinto zingasentla, kunye nokusetyenziswa okusebenzayo, eyona ndlela iphambili yokukhetha i-LED kwizibane zesitrato yile: amandla e-LED enye malunga ne-watt enye ukuya kwii-watts ezininzi, unikezelo lombala olungileyo, ubushushu bombala obungaguqukiyo, ukukhanya okukhanyayo 90. ~100 lm/W iimveliso ezikumgangatho ophezulu lolona khetho lulungileyo loyilo.Ngamandla esibane sesitalato, amandla akhanyayo afunekayo afunyanwa ngokuxuba iindidi ezininzi;Ngokumalunga neempawu zokuphuma kokukhanya, uhlobo lweLambertian, uhlobo lwe-batwing kunye nohlobo lwe-condenser lusetyenziswa ngakumbi, kodwa ngokuqhelekileyo alunakusetyenziswa ngokuthe ngqo kwizibane zesitrato, kufuneka lube ngoyilo lokusabalalisa ukukhanya kwakhona ukuhlangabezana neemfuno zokukhanya kwendlela yeempawu zokukhanya.
