Amaso ezibane zesibane se-LED Thenga amaso eZibane ze-LED eziThathu ukwenzela ukungaqondi kakuhle

Ukungaqondi kakuhle kuqala, ithemba lobomi bokwenene benkonzo liphezulu, umenzi wesibane sesibane se-LED ulindele ukuba ubomi besibane sesibane se-LED bufikelele kwiiyure ze-100,000. Nangona kunjalo, njengayo yonke imithombo yokukhanya esisiseko, ukukhanya kokukhanya kwezibane ze-LED kuye kwehlile ngokuhamba kwexesha. Ngoko ke, nangona ixesha lokukhanyisa izibane ze-LED linokuba lide kakhulu, i-MTBF ayilona qwalaselo kuphela lokumisela ubomi benkonzo. Ukubola kwezibane zesibane se-LED kuchaphazeleka kwiimeko ezininzi zokusingqongileyo ezifana nobushushu bendalo, ukufuma kunye nomoya. Impembelelo ye-attenuation engapheliyo ikwachatshazelwa kulawulo, ulawulo lwesayensi ye-thermal, iqondo langoku, kunye nokuqwalaselwa kolunye uyilo oluninzi lombane. Abathengisi abaninzi banokunikezela ngolwazi oluthile kubathengi xa bethengisa izibane zesibane se-LED, ezibangela ukulahlekisa, njengobomi benkonzo yezibane ze-LED kwiiyure ze-100,000. Iiyure ze-100,000 apha zithetha ukuba umenzi ulindele ubomi bokukhanya kwe-LED. Nangona kunjalo, njengomthombo wokukhanya wokukhanya, ukukhanya kwezibane kunenkqubo yokubola ngokuthe ngcembe kumnyama (njengokukhanya kwelanga, izibane zokulondoloza amandla). Le nkqubo ibizwa ngokuba kukubola kokukhanya. Ngoko ke, xa abathengi bethenga izibane zesibane se-LED, kufuneka bahlawule ingqalelo ekukhanyeni kwayo, bangasebenzisi ixesha, kwaye abathengi abayi kulindela ubomi bokwenene. Ukungaqondi kakuhle 2, yahlula i-engile yokukhanya yokwenyani njenge-engile eluncedo yamaso wesibane se-LED kwi-engile eluncedo kunye ne-engile yokukhanya-emitting yokwenene. Injongo yexabiso lethagethi yexabiso le-axial yamandla okukhanya-okukhupha amandla yi-angle eluncedo kunye ne-angle ye-axial ephumayo yokukhanya (indlela). Izihlandlo ezibini i-engile yesiqingatha-i-engile yexabiso yimbono (okanye i-angle ye-semi-power) yeyona angle yokukhanyisa. Ukusuka kwi-engile yesiqingatha samandla e-axial ngenxa yokuba ukukhanya kubuthathaka kakhulu kwisicelo sokwenyani, alibalanga kwi-engile eluncedo. Ngoko ke, abathengi kufuneka banikele ingqalelo kwi-angle yokukhanya yangempela yemveliso xa kuthengwa iimveliso. Xa ubala inani leemveliso ezisetyenzisiweyo kwiprojekthi, isekelwe kwi-angle yokukhanya yokwenene. Ukungaqondi kakuhle i-3, okukhona ukuqaqamba okuphezulu, kokukhona ukuqaqamba okuphezulu kwamaso wesibane se-LED kunye nokuqina kokukhanya, kunye nokukhanya okukhuphayo kubhekisa kukukhanya okukhuphayo okujoliswe kuko komgca wendlela (kumbhobho wecylindrical okhanyayo ubhekisa i-axis) Ukukhanya kokukhanya kukukhanya kwekhandlela (CD). Ngenxa yokuba ubukhulu obukhanyayo bamaso esibane ngokubanzi se-LED buncinci, ukukhanya okukhupha ukukhanya kuhlala kusebenzisa iiyunithi. Ngokuqhelekileyo, umthombo wokukhanya uya kukhanyisa ukukhanya kwawo kwithagethi eyahlukileyo ye-Domestic LED amaso anamandla ahlukeneyo. Ukususela kumbono wokuba bangaphi umsebenzi owenza amandla ngexesha elifanayo, i-current ikhawuleza, ikhoyo ngoku, umbane uneminyaka yobudala; umsinga uyacotha, amandla ombane mancinci, okanye okukhona umsinga usenza umsinga, kokukhona umbane usiba, kokukhona usiba nombane. Kwizibane zezibane ze-LED, ukuphakama kwamandla, ukuphakama kokukhazimula kwemveliso. Ukuthatha amaso amathathu ezibane ezibomvu ezikhanyayo ze-Yimei Electronics njengomzekelo, xa ukukhanya kwe-axial yi-1200mcd, okwangoku yi-40mA kunye namandla yi-0.48W; Kuyabonakala ukuba amandla ezibane ezibini phantsi kokukhanya kokukhanya ahlukile. Ke ngoko, xa abathengi bethenga amaso isibane se-LED, kufuneka bathathele ingqalelo ukuqaqamba kwayo, hayi amandla. Inqaku livela kwiintsimbi zesibane se-LED http://.
