Izinkinga Ezintathu Ezinkulu Zomkhakha Womthombo Wokukhanya We-LED kanye Nokungaqondi kahle Okuthathu Okukhulu

Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, imithombo yokukhanya ye-LED futhi kancane kancane ayihlukaniseki ezimpilweni zethu. Namuhla, ukushintshashintsha okusha nokudala, ngokungangabazeki isikhundla esiphezulu semithombo yokukhanya ye-LED ethatha izibani zansuku zonke, okuyizinkinga zemboni ye-LED kanye nokuthengwa kwe-LED. Umbuzo, yabelana nawe ngokungabaza okulethwa yilezi zinkinga: Imboni yomthombo wokukhanya we-LED izinto ezintathu ezinkulu Izinkinga zomthombo wokukhanya we-LED 1: inani. Inkinga yentengo yemikhiqizo ye-LED ibilokhu ingenye yezinkinga ezidonse ukunakwa okuningi embonini. Uma uphakeme, uzothathwa njengomuntu ongasondelene nabantu. Uma uphansi, kuzothiwa ungumuntu ozehlisayo. Ngakho-ke, imboni ayinalo izinga elicacile nelicacile. “Ukuphakama noma cha. ”Esimeni esibangela amahloni, kuyilapho intengo yomkhiqizo ikhawulelwe izindleko kanye nemakethe, isiphenduke intengo. “Ngokushesha ngangokunoka ”Umbuzo, umnikazi webhizinisi uzothengisa ngangokunokwenzeka, futhi emakethe yabathengi, kubonakala sengathi kunabantu abasebenzisa imali ukuthenga imikhiqizo. Inkinga yomthombo wokukhanya we-LED 2: inqubomgomo. I-United States isiqalile ukuvimbela ngokuphelele izibani ze-incandescent, okuzoba yithuba elikhulu lemikhiqizo ye-LED ukuncintisana endaweni yemakethe, futhi le nqubomgomo yokuvuma noma efihliwe embonini ye-LED iye yavela ngokungapheli eminyakeni yamuva. “Ubuthi benqubomgomo ”Yenza imboni ye-LED incike kakhulu ekusekelweni kukahulumeni. Nakuba wonke umuntu eqonda ukuthi imboni izothembela emakethe yamabhizinisi esikhathini esizayo, izinkampani eziningi zisalindile futhi zibone ukuthambekela kukahulumeni ekuthuthukisweni, futhi ziguqule ngokushesha ukugxila kwebhizinisi. Iningi lezinkampani ze-LED zine “Ukubutha ”Izimpawu, zicabange ukuthi ungama ehlombe lomdondoshiya, ongeke azimisele ukuma? Inkinga yesithathu yomthombo wokukhanya we-LED: umqondo. Umqondo ubuyela emuva uhileleke ezicini eziningi. Isiteshi, idizayini, umkhiqizo, ukumaketha nezinye izici azisakwazi ukulinganisa nokucabanga ngemiqondo emidala. Izinkampani eziye zashintsha kusukela ezibani zendabuko zinezinzuzo zesiteshi, kodwa eziteshini noma kumaphrojekthi okuqala, zinezinzuzo zamashaneli noma amaphrojekthi okuqala. Ukuguqulwa kwe-adaptive nakho kuyadingeka. Yibaphi abathengi esibhekene nabo? Yiziphi iziteshi abazi ngazo ngemikhiqizo? Yiziphi iziteshi abathenga ngazo imikhiqizo? Namuhla, ngokuthuthukiswa okuqhubekayo kobuchwepheshe obuhlukahlukene, sinegama lale mboni yobuchwepheshe obuphezulu. Ngaphambi komthombo wokukhanya we-LED ukuthenga ukungaqondi kahle okukhulu okuthathu, imithombo yokukhanya kwe-LED, okukodwa, futhi ukulindela impilo yesevisi yangempela kuphezulu kakhulu. Umkhiqizi we-LED ulindele ukuthi impilo ye-LED izofinyelela amahora angu-100,000 i-MTBF (isikhathi sokuhluleka esijwayelekile, indinganiso yokulinganisa ukukhanya kubakhiqizi bezibani bendabuko). Kodwa-ke, njengayo yonke imithombo yokukhanya eyisisekelo, ukugeleza kokukhanya kwe-LED nakho kubola ngokuhamba kwesikhathi. Ngakho-ke, nakuba isikhathi sokukhipha ukukhanya kwe-LED singaba side, i-MTBF akuyona ukuphela kokucatshangelwa kokunquma impilo yesevisi. Ukubola kwe-lumens ye-LED kuthinteka yizimo eziningi zemvelo ezifana nezinga lokushisa lemvelo, umswakama kanye nokukhipha umoya. Umthelela wokuncishiswa isikhathi eside nawo uyathinteka ekulawuleni, ukuphatha okushisayo, izinga lamanje, nokunye okuningi okucatshangelwayo komklamo kagesi. Abathengisi abaningi bangase banikeze amakhasimende ulwazi oluthile olungacacile ngezizathu ezithile lapho bethengisa ama-LED, okubangela ukudukisa. Isibonelo, impilo yesevisi ye-LED cishe amahora angu-100,000. Amahora angu-100,000 lapha abhekisela kuwo. Kodwa-ke, njengomthombo wokukhanya wokukhanyisa, ukukhanya kwezibani kunenqubo yokubola kancane kancane ibe mnyama (njengokukhanya kwelanga, izibani zokulondoloza amandla). Le nqubo ibizwa ngokuthi ukubola kokukhanya. Ngakho-ke, lapho uthenga i-LED, abathengi kufanele banake ijubane layo lokubola kokukhanya, bangasebenzisi isikhathi, futhi abathengi ngeke balindele okuningi mayelana nempilo yenkonzo yangempela. Umthombo wokukhanya we-LED ongaqondi kahle kokubili, thatha i-engeli yokukhanya yangempela njenge-engeli ephumelelayo. I-angle ekhanyayo ye-LED ihlukaniswe ngama-engeli asebenzayo nama-engeli okukhanyisa angempela. I-engeli ephakathi kwe-engeli ephakathi kwesiqondiso samandla aphumayo iyingxenye yesiqondiso samandla e-axial kanye ne-axial ekhipha ukukhanya (indlela) i-engeli evumelekile. Iphinda kabili i-engeli (noma i-semi -power angle) ye-engeli enguhhafu -value i-engeli yokukhanyisa yangempela. I-engeli engaphezu kwe-engeli yamandla e-axial, ngenxa yokuthi ukukhanya kubuthakathaka kakhulu ekusetshenzisweni kwangempela, akubalwa ku-engeli evumelekile. Ngakho-ke, abathengi kufanele banake i-angle yokukhanyisa yangempela yomkhiqizo lapho bethenga imikhiqizo. Lapho ubala inani lemikhiqizo esetshenziswe kuphrojekthi, isekelwe engeli langempela lokukhanyisa. Umthombo wokukhanya we-LED ukungaqondi kahle kokuthathu, amandla amakhulu, ukukhanya okuphezulu. Ukukhanya kwe-LED kukalwa ngokuqina kokukhanya. Amandla okukhipha ukukhanya abhekisela ekukhanyeni okuphumayo obheke ngakulayini wendlela (epayipini elikhanyayo eliyicylindrical libhekisela eksisi yalo), okungukuthi, ivolumu ye-optical flux ekhishwa i-engeli enezinhlangothi ezintathu zeyunithi. Ngenxa yamandla amancane akhanyayo e-LED evamile, amandla okukhipha ukukhanya kuvame ukusetshenziswa kumayunithi ezwe. Ngokuvamile, umthombo wokukhanya uzokhipha ukukhanya kwawo ngezindlela ezihlukene ngezindlela ezihlukene. Ubukhulu bemisebe yokukhanya obubonakalayo obukhishwe ku-engeli enezinhlangothi ezintathu zeyunithi ohlangothini oluthile bubizwa ngokuthi ukuqina kokukhanya, okubizwa ngokuthi ukukhanya kwe-eksisi. Kusukela emcabangweni wamandla kuya emandleni amandla ngesikhathi esifanayo, i-current iyashesha, yamanje iyashesha, ugesi mkhulu; i-current ihamba kancane, amandla kagesi mancane, noma ngesikhathi esilinganayo, lapho i-current yenza umsinga, ugesi mkhulu. Ku-LED, amandla amakhulu, ayanda ukukhanya komkhiqizo. Ukuthatha i-LED ebomvu ekhanyayo emithathu yenkampani ethile ye-elekthronikhi njengesibonelo, lapho ukukhanya kwe-axial kungu-1200mcd, okwamanje kungu-40mA futhi amandla angu-0.48W; ama-LED amathathu amhlophe akhanyayo asekukhanyeni okufanayo, yamanje ingu-18mA, futhi amandla angu-0.24W kuphela; kuyabonakala ukuthi kuyabonakala ukuthi kuyabonakala Amandla ezibani ezimbili ngaphansi kokukhanya okufanayo ahlukile. Ngakho-ke, abathengi kufanele banake ukukhanya kwe-axis yayo lapho bethenga izibani ze-LED, hhayi amandla. UZhuhai Co., Ltd. ingumkhiqizi wobuhlalu besibani se-LED onamalungelo obunikazi amaningi kazwelonke. Imikhiqizo eyinhloko ihlanganisa ukukhanya okunsomi kwe-LED, ubuhlalu besibani se-infrared LED, ubuhlalu besibani se-ultraviolet LED, ubuhlalu besibani se-LED obunemibala, njll. Ukumelana nokushisa okuphezulu, amandla aphezulu. Sineminyaka engu-16 yokuhlangenwe nakho kwesichibi se-LED. Umthamo wokukhiqiza wanyanga zonke ucishe ube yizigidi ezingama-60 zama-PC, kanti okukhiphayo ngonyaka cishe kungama-PCS ayizigidi ezingama-500. Ihlanganisa uR & D, ukukhiqizwa nokuthengisa. Uma udinga ukwazi okwengeziwe ngobuhlalu besibani se-LED, ungabonisana nensizakalo yethu yamakhasimende kuwe “Ubuhlalu belambu be-LED obufanele bokwenziwe ”Essence
