Njengoba ukukhanya kukhuphuka futhi intengo iyancipha, amandla emakethe yokukhanya okumhlophe kwe-LED emkhakheni wokukhanya kwendawo yonke ayanda. Ukusetshenziswa kokukhanya okumhlophe kwe-LED embonini yokukhanyisa jikelele kuzoba nomthelela omuhle kumasu wamandla kanye namasu okuvikela imvelo yezwe noma isifunda. Ukukhanya okumhlophe kwe-L E d kunomthamo omncane, ukupakishwa kwendiza, noma ukusebenzisa izinhlanganisela eziningi noma eziningi ngokuya ngendawo noma isimo, futhi kunekhalori yokushisa ephansi, impilo ende ekhanyayo (ngaphezu kwamahora angu-50,000), akulula ukuphuka, ngokwedlulele. ukumelana nokuzamazama komhlaba kanye nokumelana nokushaqeka ngokwedlulele kanye nokumelana nokushaqeka ngokwedlulele kanye nokumelana nokushaqeka ngokwedlulele nokumelana nokushaqeka ngokwedlulele nokumelana nokushaqeka ngokwedlulele kanye nokumelana nokushaqeka ngokwedlulele kanye nokushaqeka ngokwedlulele ukumelana nokuguquguquka futhi ukumelana nokushaqeka ngokwedlulele futhi ukumelana nokushaqeka ngokwedlulele futhi ukumelana nokushaqeka kakhulu futhi kakhulu ukushaqeka -ukungazweli nokushaqeka kakhulu -iyamelana nokushaqeka kakhulu -iyamelana futhi ishaqeke kakhulu -iyamelana nokushaqeka kakhulu -iyamelana nokushaqeka kakhulu -iyamelana nokushaqeka kakhulu -iyamelana futhi nokushaqeka kakhulu -iyamelana futhi ishaqeke kakhulu -iyamelana futhi kakhulu ukushaqeka -ayizweli futhi ishaqeke kakhulu -iyamelana futhi ishaqeke kakhulu -iyamelana nokushaqeka kakhulu -iyamelana nokushaqeka kakhulu -iyamelana futhi imelana kakhulu t o ukwethuka. Ukumelana nesiguli kungasetshenziswa ezimweni eziyingozi nakwezinye izici. Ukusebenza kahle kokukhishwa kokukhanya okumhlophe kwe-LED kuphezulu, izinsimbi eziningi njengokonga amandla, imisebe engashisi, i-mercury engaqukethe, akukho zinkinga zokungcola kanye nokwelashwa kwemfucuza, njll., zithathwa njengenkanyezi yakusasa "ngokukhanya okuluhlaza." umthombo". Shintshanisa ama-incandescent amalambu kanye nezibani ze-fluorescence (nsuku zonke) emakethe yokukhanyisa okwamanje. Ukuthuthukiswa kwemboni yezibani zamalambu amhlophe e-LED kuzothinta amandla kanye namasu okuvikela imvelo yezwe nesifunda. Ngakho-ke, amazwe ahlukahlukene asekele isibonelo semboni yokukhanyisa i-semiconductor ye-LED njengentuthuko enkulu kazwelonke. Imakethe ye-LED ekhanyayo emhlophe inethemba elikhulu embonini ye-LED enemithombo eqinile yokukhanyisa engase ibe khona emakethe embonini ye-LED. Ngokuka-FROS & Izilinganiso zika-SULLIVAN, imakethe yomthombo wokukhanyisa womhlaba wonke ikhuphuke ngezinga elizinzile lokukhula lika-5% ngonyaka; okuyikhona, ama-LED amhlophe angase angene emakethe ye-incandescent kanye nemakethe yokukhanya kwe-fluorescent. Le mikhiqizo yomibili iwukukhanya kwabantu okudume kakhulu. Umthombo wokukhanya, amandla emakethe okukhanya okumhlophe kwe-LED esikhathini esizayo kungathiwa makhulu impela. 1. Ukukhanya okumhlophe kwe-LED ukukhanya -isimiso esikhipha ukukhanya okumhlophe ukukhanya kwe-LED indlela yokukhanyisa ihlukaniswe ikakhulukazi izinhlobo ezimbili: uhlobo lwekristalu olulodwa nohlobo lwe-polycrystalline olusebenzisa ukukhanya kwe-LED -emitting diode. Eyokuqala iwuhlobo olulodwa lwekristalu, okungukuthi, i-monochrome LED light -emitting diode kanye ne-fluorescent powder ehambisanayo, njengendlela yokukhanyisa yokukhanya kwelanga, kusetshenziswa i-LED light -emitting diode. Ngokuvamile kunezindlela ezimbili. Enye indlela ukuthi ukukhanya okuluhlaza okwesibhakabhaka kwe-LED ekhanyayo i-diode ivuselela impushana ye-fluorescent ephuzi ukukhiqiza ukukhanya okumhlophe. Okunye ukukhanya kwe-ultraviolet LED evuselela i-RGB three -wave long fluorescent powder ukukhiqiza ukukhanya okumhlophe. Abakhiqizi abaningi babambe iqhaza kakhulu ocwaningweni lwama-LED akhanyayo amhlophe. Ngokuvamile baqala ukuthuthukisa kanye nokukhiqizwa ngobuningi kusuka ku-Blu -ray LED. Ngobuchwepheshe bobuchwepheshe be-Blu -ray LED, i-Baiguang LED iyathuthukiswa. Nokho Ukusebenza kahle kokukhanyisa kwe-LED ukukhanya okuluhlaza akwanele. Abakhiqizi abaningi baqala ukuthuthukisa ngenye indlela ukuthuthukisa ukukhanya kwe-ultraviolet LED. Ukukhanya okuluhlaza kungcono. Futhi indlela ye-UV LED kanye ne-RGB amagagasi amathathu empushana ye-fluorescent, ubuchwepheshe obuyinhloko ku-high-efficiency fluorescence synthesis, okungukuthi, indlela yokunamathisela ngempumelelo impushana ye-fluorescent kubuchwepheshe. Enye i-polycrystalline, ngisho noma i-2 noma ngaphezulu ehambisanayo engu-2 -color LED light -emitting diode noma i-3 primary LED light -emitting diode ixutshwa ukwenza ukukhanya okumhlophe. Kusetshenziswa uhlobo lwe-multi-crystalline lokukhanya okumhlophe, ngoba amandla kagesi okushayela, ukuphuma kokukhanya, izici zokushisa nempilo yemibala ehlukene ye-LED light -emitting diode kuhlukile. Indlela yokukhiqiza ukukhanya okumhlophe ohlotsheni lwe-LED iyinkimbinkimbi. Ngenxa yenani elikhulu lama-LED light -emitting diode, izindleko ze-polycrystalline LED nazo ziphezulu. Uma kusetshenziswa uhlobo olulodwa lwekristalu Idizayini kumjikelezo wedrayivu izoba lula. Ngakho-ke, abakhiqizi abaningi manje basebenzisa ama-LED e-crystal eyodwa njengendlela yokuthuthukiswa kokukhanya okumhlophe kwe-LED. 2. Ukuthengisa: Ubuchwepheshe be-LED buye bathuthuka ngokushesha eminyakeni yamuva, ukukhanya kuye kwaqhubeka nokwanda, futhi amanani aqhubeka ehla. Ngaphezu kwemakethe yokuqala ye-LED, imakethe iqhubekile nokukhula ekukhanyeni okuvamile. Kokubili ukukhanya nentengo kuye kancane kancane kusondele emthonjeni wendabuko. Ngenxa yeziyaluyalu ezindaweni ezikhiqiza uwoyela emhlabeni, inkinga yokushoda kwamandla emhlabeni isiphinde yaba into egxilwa kakhulu kuyo. Ukuthuthukiswa kwemboni ye-LED kuzoba nomthelela omkhulu kumgomo wamandla kanye nokuvikelwa kwemvelo esifundeni. I-United States, Japan, Europe, kanye neSouth Korea bonke basungule i-R & D izinhlangano zokusheshisa ukuthuthukiswa kobuchwepheshe nokukhiqiza ngobuningi. Kulesi sigaba, kusenebanga elide ukusuka esikhathini sokungena enkathini yokukhanyisa kwe-LED okumhlophe. Ngenxa yokucatshangelwa kanye nezindleko zokucatshangelwa kokukhanya okumhlophe kwe-LED kanye nezindleko, cishe u-100LM/W wokukhanya okumhlophe kwe-LED ngo-2010, kanye no-200LM/W ngo-2020. Uma inqubo yokukhanya okumhlophe kwe-LED ishesha, ingavela kancane imikhiqizo edayiswa ngo-2005, nangemuva kuka-2010. Ngokwemakethe yokukhanyisa, ngokusho kwe-FROST & Izilinganiso zika-SULLIVAN, usayizi wemakethe yomhlaba wonke we-incandescent light bulb kanye nezibani zelanga ngo-2000 wawucishe ube ngama-dollar ayizigidi eziyizinkulungwane ezingama-4.3, kanti izinga lokukhula konyaka lalicishe libe ngama-5%. Kwakucishe kube izikhathi ezi-2.5 kunosayizi wemakethe ye-LED ebonakalayo emhlabeni wonke ngo-2000. Ngakho-ke, indawo yokuthuthukiswa kwemakethe yokukhanyisa sikhulu impela. I-Reed Electronics Research Global White -ray LED ilinganiselwa ukuthi izokhula ibe usayizi wemakethe wama- $ 118 wezigidi ngo-2000. Eminyakeni emithathu ezayo, izogcina izinga lokukhula elilinganiselwa ku-40%. Ngo-2003, yafinyelela usayizi wemakethe wama- $ 270 wezigidi. Ngokuzayo, izindleko zokukhanya okumhlophe kwe-LED zizokwehliswa nakakhulu. Ngaphandle kwe-backlight yeselula ekhona kanye ne-backlight ye-LCD encane, uma imakethe yokukhanyisa kwendawo yonke iqala, imakethe ye-LED ekhanyayo izoba namandla amakhulu emakethe. Ukukhanya okumhlophe kwe-LED kulinganiselwa ukuthi bekukhona Ekuqaleni, amandla emakethe azokhishwa kancane kancane, futhi isidingo sizokhula kancane kancane. Kulesi sigaba, ukusetshenziswa kokukhanya okumhlophe kwe-LED kusetshenziselwa ikakhulukazi izibani zokufunda, izibani zokuhlobisa, njll. mayelana nokukhanyisa, futhi cishe u-95% wama-95% asele awemithombo emincane yokukhanyisa i-LCD. 1. Imakethe enomthombo wokukhanya ongemuva kwesikrini weselula enombala emakethe ye-LED emhlophe inkulu kakhulu. Nakuba ukusetshenziswa okuphezulu kwe-LED emhlophe kungase kufike emahoreni angu-100,000, kufanele kusetshenziswe endaweni yamanje ephansi. Njengamanje, lo mkhiqizo usetshenziswa kakhulu emithonjeni yokukhanya yangemuva emincane. Ngokombono wezimakethe zezicelo ezihlukahlukene, ngoba isikrini sombala amafoni omakhalekhukhwini adinga ukubhangqwa nokukhanya okumhlophe kwe-LED njengomthombo we-backlight, futhi amafoni omakhalekhukhwini wesikrini sombala azoba umkhuba wokuthuthukiswa kwemakethe yamaselula eminyakeni embalwa ezayo. Ngokwesibikezelo semakethe yemboni yomakhalekhukhwini besikrini sombala, ingxenye yomakhalekhukhwini bemibala ngo-2004 ilinganiselwa ku-40 % Ngo-2005, ilinganiselwa ukuthi izofinyelela ku-55% kuya ku-60%. Cishe izingcezu eziyizigidi eziyizinkulungwane ezingama-5-1, ngaphezu kwalokho, ngenxa yokuthi ukukhanya okumhlophe kwe-LED sekuqalile ukusebenzisa ukukhanya kwekhamera yedijithali enamathiselwe umakhalekhukhwini, ingxenye yomakhalekhukhwini enamathiselwe ikhamera yedijithali kulo nyaka imayelana ne-15%, futhi kulindeleke ukuthi inyuke ibe ngu-20% ngonyaka ozayo. 4, isidingo sonyaka singaba yizigidi ezingama-400. Okwesibili, ngokwemithombo ye-backlight ku-PDA kanye namakhamera edijithali, ngokusho kokulinganisa okulinganiselwe kwe-Economic Capital Center ye-Zhuhai Industry Research Institute, i-PDA yathumela cishe amayunithi ayizigidi ezingu-25 ngo-2003, futhi ukusetshenziswa ngakunye kwama-LED amhlophe angaba ngu-6-8 iyunithi. Kulinganiselwa ukuthi kudingeka izingcezu ezingaba yizigidi ezingu-50; uma kusetshenziswa ikhamera yedijithali, inani lamakhamera edijithali ngo-2003 emhlabeni lilinganiselwa ezigidini ezingama-30. Ngokwaleli phuzu lokubuka, isidingo sokukhanya okumhlophe kwe-LED sisazoncika emakethe yomthombo wokukhanyisa wamafoni omakhalekhukhwini esikrini sombala. 2. I-White -light LED okwamanje isebenzisa ukukhanya okungemuva kwe-LCD okunosayizi omncane njengokukhanya kwayo okuyinhloko okubandayo kwe-cathode fluorescent (CCFL) uma kuqhathaniswa nobunye ubuchwepheshe bobuchwepheshe be-backlight inezinzuzo zokukhanya nokusebenza okuphezulu kokukhanya. Kuqinile, kodwa ngenxa yokuthi ukukhanya okubandayo kwe-cathode fluorescent ye-diameter encane yeshubhu kunzima kakhulu futhi izindleko azikho inzuzo enkulu, isibani esibandayo se-cathode fluorescent sisetshenziswa kakhulu ngamayintshi angu-4 noma ngaphezulu (futhi ubukhulu befoni ephathekayo bungaphezulu. ngaphezu kwamayintshi angu-1.5 ukuya ku-2.2. Kuyintshi, ikhamera yedijithali ibhekwa kancane futhi usayizi uphakathi kwalapha). Ngokuya ngemithombo yokukhanya kwe-backlight ye-LCD enkulu, isibani samanje esibandayo se-cathode fluorescent sinenzuzo ephelele ngokuya ngosayizi omkhulu kanye nentengo.
