Amaso esibane sesibane se-LED Thenga ukungaqondi kakuhle okuNtathu

Ukungaqondi kakuhle 1, ukulindela ubomi benkonzo yokwenyani kuphezulu kakhulu umenzi wesibane sesibane se-LED ulindele ukuba ubomi bentsimbi yesibane se-LED bufikelele kwiiyure ezingama-100,000. Nangona kunjalo, njengayo yonke imithombo yokukhanya esisiseko, ukuhamba kokukhanya kokukhanya kwesibane se-LED kuye kwehlile ngokuhamba kwexesha. Ngoko ke, nangona ixesha lokukhanyisa izibane zesibane se-LED linokuba lide, 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 iphinda ichaphazeleke kulawulo, ulawulo lwe-thermal, inqanaba langoku, kunye nezinye izinto ezininzi zokuqwalaselwa koyilo lombane. Abathengisi abaninzi banokubonelela abathengi ngolwazi olungenangqondo ngezizathu ezithile xa bethengisa amaso esibane se-LED, okubangela ukulahlekisa. Ngokomzekelo, ubomi benkonzo yezibane ze-LED malunga neeyure ze-100,000. Iiyure ze-100,000 apha zibhekiselele kubomi obulindelekileyo bokukhanya kwe-LED kumenzi. Nangona kunjalo, njengomthombo wokukhanya wokukhanya, ukukhanya kwezibane kunenkqubo yokubola ngokuthe ngcembe kumnyama (njengokukhanya kwelanga, izibane zokulondoloza amandla). Le nkqubo ibizwa ngokuba kukubola kokukhanya. Ke ngoko, abathengi kufuneka banikele ingqalelo kwisantya sokubola kokukhanya xa kuthengwa amaso esibane se-LED, ungasebenzisi ixesha. Abathengi abayi kulindela elona xesha lilindelekileyo lokuphila. Yahlula i-engile yokukhanya yokwenyani njenge-engile esebenzayo yamaso wesibane se-LED kwi-engile esebenzayo kunye ne-engile yokukhanya yokukhanya yokwenyani njenge-engile esebenzayo yamaso wesibane se-LED. I-angle phakathi kwe-angle phakathi kolwalathiso lwamandla okukhupha isiqingatha solwalathiso lwamandla e-axial kunye ne-axial ekhupha ukukhanya (indlela) i-angle esebenzayo. Izihlandlo ezibini i-engile (okanye i-semi-power angle) yesiqingatha-i-engile yexabiso yeyona engile yokukhanyisa. I-angle ngaphaya kwe-angle yamandla e-axial, ngenxa yokuba ukukhanya kubuthathaka kakhulu kwisicelo sangempela, akubaleli kwi-angle esebenzayo. Ngoko ke, abathengi kufuneka banikele ingqalelo kwi-angle yokukhanya yangempela yemveliso xa kuthengwa iimveliso. Xa kubalwa inani leemveliso ezisetyenzisiweyo kwiprojekthi yokubala, eyona engile yokukhanyisa iya kulawula. Ukungaqondi izinto ezintathu, amandla amakhulu, kokukhona ukuqaqamba kwamaso wesibane se-LED alinganiswa ngokukhanya okukhuphayo. Ukukhanya okukhupha ukukhanya kubhekiselele ekukhanyeni okukhupha ukukhanya kwindlela yomgca wendlela (kwi-cylindrical luminous pipe ibhekisela kwi-axis yayo) Ukukhanya okukhanyayo, iyunithi yikhandlela (CDLA, CD). Ngenxa yokuba ukukhanya okukhanyayo kwezibane eziqhelekileyo ze-LED zincinci, ukukhanya okukhanyayo kudla ngokusetyenziswa kwiiyunithi zelizwe. Ngokubanzi, umthombo wokukhanya uya kukhupha ukukhanya kwawo kumacala ahlukeneyo kumacala ahlukeneyo. Ukukhanya okubonakalayo kwemitha yokukhanya ekhutshwe kwi-engile ye-dimensional emithathu yeyunithi kwicala elithile kuthiwa yi-intensity yokukhanya, ekubhekiswa kuyo njengokukhanya kwe-axis. Ukususela kwingcamango yamandla ukuya kumandla ombane ngexesha elifanayo, i-current ikhawuleza, i-current ikhawuleza, umbane mkhulu; umsinga uyacotha, amandla ombane mancinci, okanye ngexesha elilinganayo, okukhona umsinga usenza umsinga, umbane mkhulu. Kwizibane zezibane ze-LED, amandla amakhulu, aphezulu ukuqaqamba 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; izibane ezintathu ezimhlophe zesibane se-LED ziphantsi kokukhanya okufanayo, okwangoku yi-18mA, amandla yi-0.24W kuphela yi-0.24w Kuyabonakala ukuba amandla ezibane zombini phantsi kokukhanya okufanayo ahlukile. Ke ngoko, abathengi kufuneka bathathele ingqalelo ukuqaqamba kwayo xa uthenga amaso isibane LED, hayi amandla.
