Yize imisebe ye-UV ingaba yingozi ezintweni eziphilayo empilweni yansuku zonke, njengokushiswa yilanga, imisebe ye-UV izonikeza imiphumela eminingi ezuzisayo emikhakheni ehlukahlukene. Njenge-LED ebonakalayo ebonakalayo ebonakalayo, ukuthuthukiswa kwama-UV LEDs kuzoletha lula kakhulu kwizicelo eziningi ezahlukahlukene.
Intuthuko yakamuva yezobuchwepheshe ikhulisa izingxenye zemakethe ye-UV eholwa ekuphakameni okusha kokuqamba komkhiqizo nokusebenza. Onjiniyela Abaklami babona ukuthi ubuchwepheshe obusha be-UV LED bungakhiqiza inzuzo enkulu, amandla kanye nokonga isikhala ngokuqhathaniswa nobunye ubuchwepheshe obuhlukile. Ubuchwepheshe be-UV LED elandelayo bunezinzuzo ezinhlanu ezibalulekile, yingakho imakethe yalobu buchwepheshe kulindeleke ukuthi ikhule ngama-31% eminyakeni emihlanu ezayo.
Uhla olubanzi lokusetshenziswa
I-spectrum yokukhanya kwe-ultraviolet iqukethe wonke ama-wavelength kusuka ku-100nm kuya ku-400nm ubude futhi ngokuvamile ahlukaniswe ngama-ultraviolet amade, abizwa nangokuthi ama-medium wave), UV-C (100-280 Nanometers, futhi eyaziwa ngokuthi iDemo-wave ultraviolet).
Ukusetshenziswa kwamazinyo kanye nezicelo zokuhlonza bekuyizinhlelo zokuqala ze-UV LEDs, kepha ukusebenza, izindleko nokuqina kwezinzuzo, kanye nokukhuphuka komkhiqizo, kwanda ngokushesha ukusetshenziswa kwe-UV LEDs. Ukusetshenziswa kwamanje kwe-UV LEDs kufaka phakathi: Izinzwa ze-Optical and Millengs (230-400nm), ukuqinisekiswa kwe-UV (ama-barcode (230-205nm), Ukuhlaziywa kwama-Proten Ukuphrinta kwe-Ink (300-365nm), okukhohlisayo (375-395nm), inzalo engaphezulu / inzalo yezimonyo (390-410NM).
Umthelela wezemvelo - Ukusetshenziswa kwamandla okuphansi, imfucuza engaphansi futhi akukho zinto eziyingozi
Uma kuqhathaniswa nolunye ubuchwepheshe obuhlukile, ama-UV LED anezinzuzo ezicacile zemvelo. Uma kuqhathaniswa namalambu we-fluorescent (CCFL), ama-UV LED anokusebenzisa amandla angama-70%. Ngaphezu kwalokho, i-UV LED yi-rohs eqinisekisiwe futhi ayinayo iMercury, into eyingozi evame ukutholakala kubuchwepheshe be-CCFL.
Ama-UV LED amancane ngosayizi futhi ahlala isikhathi eside kunama-CCFL. Ngoba ama-UV LEDs ahamba nge-vibrate- futhi amelana nokwethuka, ukuqhekeka akuvamile, kunciphisa imfucuza kanye nezindleko.
Increase isikhathietity
Eminyakeni eyishumi edlule, ama-UV LED aphonswe inselelo ngokwemibandela yempilo yonke. Naphezu kwezinzuzo zayo eziningi, ukusetshenziswa kwe-UV LED kwehle kakhulu ngoba ugongolo lwe-UV luvame ukubhidliza i-resin ye-epoxy ye-LED, ukunciphisa impilo ye-UV eholwa emahoreni angaphansi kwama-5,000.
Isizukulwane esilandelayo sobuchwepheshe be-UV LED sibonisa i-epoxy endoxy "noma" evinjelwe "noma" ukumelana ne-UV ", ngenkathi enikela ngesikhathi sokuphila amahora angama-10,000, namanje kude nokwanele kwezicelo eziningi.
Ezinyangeni ezimbalwa ezedlule, ubuchwepheshe obusha buxazulule le nselelo yobunjiniyela. Isibonelo, iphakethe elinama-to-46 elinama-lens engilazi lalisetshenziselwa ukufaka esikhundleni selensi ye-epoxy, edlulisela impilo yayo yenkonzo okungenani amahora ayishumi kuya kwayishumi kuya ku-50,000. Ngale nselelo enkulu yobunjiniyela nezinkinga ezihlobene nokuzinza ngokuphelele kwe-wavelength exazululwe, ubuchwepheshe be-UV LED buye baba inketho ekhangayo yenombolo ekhulayo yezicelo.
Pisivikelo
I-UV LED futhi inikezela ngezinzuzo zokusebenza okubalulekile ngaphezulu kwenye ubuchwepheshe obunye. Ama-UV LED ahlinzeka nge-angle encane e-angle kanye nogongolo oluyunifomu. Ngenxa yokusebenza kahle okuphansi kwe-UV LEDs, Onjiniyela abaningi be-Design bafuna i-beam angle ekhulisa amandla okukhipha endaweni ethile okuhlosiwe. Ngamalambu ajwayelekile we-UV, onjiniyela kufanele bathembele ekusebenziseni ukukhanya okwenele ukukhanyisa indawo ngokufana nokuhlangana. Okwe-UV LEDs, isenzo selensi sivumela iningi lamandla okukhipha we-UV aholwa lapho kudingeka khona, okuvumela i-angle yokuphuma.
Ukufanisa lokhu kusebenza, abanye ubuchwepheshe obuhlukile bangadinga ukusetshenziswa kwamanye ama-lens, bengeza izindleko ezengeziwe kanye nezidingo zesikhala. Ngoba ama-UV LEDs awadingi ama-lens angeziwe ukufeza ama-beam anger aqine kanye namaphethini we-beam afanayo, ukusetshenziswa kwamandla okuphansi, ukuqina kwamandla, ukuqina kwamandla, ukukhuphuka kwezindleko, izindleko ze-UV zibiza uhhafu wokuqhathanisa nobuchwepheshe be-CCFL.
Izinketho ezizinikezele ezisebenzayo zakha isixazululo se-UV se-LED sohlelo oluthile noma usebenzise ubuchwepheshe obujwayelekile, obekulokhu kusebenza ngokwengeziwe ngokuya ngezindleko nokusebenza. Ama-UV LED asetshenziswa ezinhlwini eziningi ezimweni eziningi, kanye nokuvumelana kwephethini ye-beam kanye namandla kulo lonke uhlu kubalulekile. Uma umphakeli oyedwa ehlinzeka lonke uhlu oluhlanganisiwe oludingekayo kwisicelo esithile, inani lezosebenzi lezinto zokwenziwa lincishisiwe, inani labaphakeli liyancishiswa, futhi i-array ingahlolwa ngaphambi kokuthumela unjiniyela wokuqamba. Ngale ndlela, ukuthengiselana okumbalwa kungagcina izindleko zobunjiniyela nokuthengwa kwempahla futhi kunikeze izixazululo ezisebenzayo ezihambisana nezidingo zohlelo lokusebenza lokugcina.
Qinisekisa ukuthola umphakeli onganikeza izixazululo ezisebenza ngempumelelo yangokwezifiso futhi angakwazi ukuklama izixazululo ngokukhethekile izidingo zakho zohlelo lokusebenza. Isibonelo, umphakeli oneminyaka eyishumi yokuhlangenwe nakho ku-PCB Design, ama-Optics ngokwezifiso, ukulandelela kwangokwezifiso nokubumba kuzokwazi ukunikela ngezinketho eziningi ezingezindleko nezimali ezisebenza kahle kakhulu.
Ekuphetheni, ukuthuthuka kwakamuva kwezobuchwepheshe kuma-UV LEDs kuxazulule inkinga yokuzinza ngokuphelele futhi kwandiswa kakhulu isikhathi sabo sokuphila kuze kube amahora angama-50,000. Ngenxa yezinzuzo eziningi ze-UV LEDs ezifana nokuqina okuthuthukile, azikho izinto eziyingozi, ukusetshenziswa kwamandla okuphansi, ukulungiswa kwezindleko, ubuchwepheshe obusebenzayo, ubuchwepheshe buthola ukuthengiswa ngezinto ezimakethe, izimboni futhi eziningi zisebenzisa inketho ekhangayo.
Ezinyangeni naseminyakeni ezayo, kuzoba nokuthuthuka okwengeziwe, ikakhulukazi ohlelweni olusebenzayo. Ukusetshenziswa kwama-UV LEDs kuzokhula ngokushesha okukhulu.
Inselelo enkulu elandelayo ye-UV LED Technology isebenza kahle. Ukuze uthole izinhlelo zokusebenza eziningi usebenzisa ama-wavelength angaphansi kwama-365nm, njenge-Phototherapy, ama-distinfection wamanzi kanye nokwelashwa kwama-polymer, amandla okukhipha ama-UV ama-LED angama-5% -8% wamandla okufaka kuphela. Lapho i-wavelength ingu-385NM nangaphezulu, ukusebenza kahle kwe-UV LED kukhuphuka, kepha futhi kungu-15% kuphela wamandla okufaka. Njengoba ubuchwepheshe obuqhamukayo buqhubeka ukubhekana nezinkinga ezisebenzayo, izinhlelo eziningi zizoqala ukwamukela ubuchwepheshe be-UV LED.
