Yiziphi Izici Eziyinhloko Zemaski Yobuso Esebenzayo Ye-LED?

Isikhumba esikhanyayo nesikhanyayo singaphezu nje kwesitayela; kuyisibonakaliso sokuthi inqubo yakho yokunakekela isikhumba iyasebenza. Uma ubulokhu unesifiso sokufunda ngamaski obuso e-LED, awuwedwa. Lawa madivayisi athembisa indlela engahlaseli, yasekhaya eya ezinzuzweni eziningi zesikhumba ezazidinga ukuvakashelwa emtholampilo. Kodwa ngamamodeli amaningi kangaka kanye nezimangalo, ungazi kanjani ukuthi yiziphi izici ezibaluleke ngempela? Lesi sihloko sihlola izinto ezibalulekile ezihlukanisa imaski yobuso e-LED esebenza kahle kakhulu kumaqhinga, okukusiza ukuthi wenze isinqumo esinolwazi ngaphambi kokutshala isikhathi nemali.

Kungakhathaliseki ukuthi ungumuntu ozinikele ekunakekelweni kwesikhumba, usanda kuqala ukwelashwa ngokukhanya, noma umuntu ofuna ukwelashwa okuqondiswe ngqo kwezinduna, ukuguga, noma ukuguquka kwebala, imaski efanele ingashintsha indlela osebenza ngayo ekhaya. Qhubeka ufunda ukuze uthole ulwazi olujulile ngobuchwepheshe, izinto ezicatshangelwayo zokuklama, izici zokuphepha, kanye nemisebenzi elula ukuyisebenzisa echaza imaski yobuso ye-LED esebenzayo.

Ubude Bamagagasi Okukhanya Nokwelashwa Kombala

Imaski yobuso ye-LED esebenzayo incike kumaza okukhanya asekelwe ngokwesayensi ukuze kufezwe izinzuzo zesikhumba eziqondiwe. Imibala ehlukene yokukhanya ingena esikhumbeni ngokujula okuhlukahlukene futhi isebenzisana nezingxenye zamaseli kanye nama-chromophores ukuze kuvele izimpendulo ezithile zezinto eziphilayo. Isibonelo, ukukhanya okubomvu kuvame ukuwela ngaphakathi kobubanzi obungu-630-700 nm futhi kwaziwa ngokuvuselela i-mitochondria ngaphakathi kwamaseli esikhumba. Le nqubo ithuthukisa ukukhiqizwa kwe-ATP futhi isekela ukulungiswa kwamaseli kanye nokwakheka kwe-collagen, okungasiza ekunciphiseni imigqa emincane, kuthuthukise ukuthungwa kwesikhumba, futhi kukhuthaze ukubukeka kwentsha. Ukukhanya okuseduze kwe-infrared, okuvame ukuba cishe ngu-800-850 nm, kungena ngokujulile futhi kungasiza ekulungisweni kwezicubu ezijulile futhi kuthuthukise ukujikeleza kwegazi. Ukukhanya okuluhlaza okwesibhakabhaka, ngokuvamile okuphakathi kuka-405-420 nm, kunendlela ehlukile: kuhlasela ama-porphyrins akhiqizwa amabhaktheriya abangela induna, okuholela emphumeleni wokulwa namagciwane onganciphisa ukuqhekeka okusebenzayo kanye nama-pores avalekile.

Imaski esebenzayo ngeke ibe nombala owodwa nje kuphela; izonikeza ama-wavelength amaningi angasetshenziswa ngawodwana noma ngokuhlanganiswa ukubhekana nezinkinga ezahlukahlukene. Amadivayisi asezingeni eliphezulu avame ukunikeza amandla aqinisekisiwe ngokwezokwelapha ku-wavelength ngayinye. Ukuba nama-wavelength amaningi, ahlukile kuvumela abasebenzisi kanye nochwepheshe bezokunakekelwa kwesikhumba ukwenza ngezifiso ukwelashwa—ukuhlanganisa ukukhanya okuluhlaza okwesibhakabhaka nokubomvu kubantu abaphatha kokubili induna kanye nokuvuvukala, noma ukwengeza i-near-infrared kubasebenzisi abadinga ukuvuselelwa kwezicubu ezijulile. Ngaphezu kwalokho, ubumsulwa be-spectral kanye nokuvumelana kwama-LED kubalulekile: amadivayisi ashibhile ngezinye izikhathi asebenzisa ama-LED akhipha ububanzi obubanzi, obuncishisiwe, okunciphisa ukusebenza kahle. Funa abakhiqizi abacacisa ububanzi obuqondile be-wavelength futhi banikeze idatha yezokwelapha noma yelabhorethri esekela izimangalo zabo.

Okunye okucatshangelwayo ibhalansi phakathi kobude besikhathi nesikhathi sokuvezwa. Ngisho noma ubude besikhathi bufanele, ukuvezwa okunganele noma ukukhanya okuphansi kakhulu kungenza ukwelashwa kungasebenzi. Ngokuphambene nalokho, ukuqina okuphezulu kakhulu ngaphandle komklamo ofanele wokuphepha kungabangela ukungakhululeki noma imiphumela emibi. Amamaski asebenza kahle kakhulu alinganisa ubude besikhathi kanye nomphumela ukuze alethe imithamo yokwelapha ehlala ngaphakathi kwemingcele ephephile. Ngamafuphi, amakhono okwelapha ngombala wemaski ayisisekelo; kumele abe aqondile, asekelwe ebufakazini, futhi aguquguquke ukuze anikeze imiphumela enenjongo kuzo zonke izinkinga zesikhumba nezinhlobo ezahlukene.

Ukuqina, Ukufana, kanye Nesikhathi Sokwelashwa

Ukuqina kanye nokufana kuyizinto ezimbili ezinquma ukuthi ukukhanya okulethwa yimaski yobuso kuzosebenzisana kahle yini nezicubu zesikhumba. Ukuqina, okuvame ukulinganiswa njengokukhanya (mW/cm²), kunquma ukuthi amandla angakanani afinyelela amaseli ngesikhathi esithile. Ukuqina okuphansi kakhulu kungasho izikhathi ezinde ezinezinzuzo ezincane, kuyilapho ukuqina okuphezulu kuqinisekisa ukuthi imikhawulo yokwelapha ihlangatshezwa ngaphakathi kwesikhathi sokwelashwa esifanele. Izifundo zesayensi zibonisa ukuthi ubuningi bamandla athile—okuvezwa njengama-joules ngesentimitha lesikwele—buvame ukudingeka ukuze kufezwe izimpendulo zamaseli ezifiselekayo. Ama-masks asebenzayo alinganisa ukuphuma kwe-LED ukuze kufinyelelwe kulezi zigaba ngezikhathi ezilungele ukusetshenziswa ekhaya njalo, ngokuvamile kusukela emizuzwini embalwa kuya kwesigamu sehora kuye ngendlela yokwelapha.

Ukufana kubhekisela ekutheni ukukhanya kusatshalaliswa ngokulinganayo kangakanani ebusweni bemaski. Ukusatshalaliswa okungaguquki kudala izindawo ezishisayo nezindawo ezibandayo: ezinye izingxenye zobuso zingase zithole imithamo yokwelapha kanti ezinye zithola amandla anele. Lokhu kungalingani kwenza imiphumela ingabikezeleki futhi kungadikibalisa abasebenzisi abalindele ukuthuthuka okuqhubekayo. Amamaski asezingeni eliphezulu asebenzisa ama-LED amaningi abekwe futhi asatshalaliswa ukuqinisekisa ukumbozwa okufanayo, ngokuvamile afaka izendlalelo ezibonisa ukukhanya, amaphaneli okusabalalisa, noma izinhlangano zamalensi amancane ukusabalalisa ukukhanya ngokulinganayo. Ukulingana nesimo semaski nakho kudlala indima ebalulekile ekuqinisekiseni ukulethwa okufanayo; umklamo oqinile, onemiphetho obamba ama-LED eduze kwesikhumba ngokuvamile uzohlinzeka ngokudluliselwa kwamandla okungcono kuneshidi eligoqekayo, elifakwe kalula.

Isikhathi sokwelashwa sihlotshaniswa ngokwemvelo kokubili ukuqina kanye nokufana. Amamaski anikeza ukukhanya okuphezulu, okusatshalaliswa ngokulinganayo angafeza ubuningi bamandla obusebenzayo ngezikhathi ezimfushane.
