Ihlola Isimiso Esisebenzayo Somshini we-PDT we-LED ngemininingwane

Umshini we-PDT LED iyidivayisi eyinkimbinkimbi ehlanganisa ubuchwepheshe be-LED obuphambili nezinhlelo zokulawula ezinembile. I-LED, noma i-Light Emitting Diode, iyisemiconductor ekhipha ukukhanya lapho amandla kagesi edlula kuyo. I-PDT egameni kungenzeka imele i-Photo-Thermally Activated Diode Technology, ekhombisa indlela ehlukile yokwenza kusebenze ehlanganisa ukukhanya nokushisa ukuze kusebenze okuthuthukisiwe.

Umgomo Wokusebenza Womshini we-PDT we-LED

Ukusebenza komshini we-PDT LED kuzungeza izingxenye ezibalulekile ezimbalwa, kuqinisekisa ukusebenza kahle.
- I-Photon Emission: Inqubo eyisisekelo kunoma yimuphi umshini we-LED ukukhishwa kwe-photon. Emshinini we-PDT LED, lokhu kukhishwa kulawulwa ngokucophelela ukuze kuqinisekiswe ukuphuma kokukhanya okufanayo. Ama-LED, noma ama-light-emitting diode, ahlelwa ngohlelo, okuvumela ukulawula okunembile phezu komthombo wokukhanya. Lolu hlelo lubalulekile ezinhlelweni zokusebenza ezidinga ukukhanya okungaguquki, njengokukhanya kwemboni noma izithombe zezokwelapha ezinembayo.
- I-Control Circuitry: I-control circuitry yomshini we-PDT LED isistimu eyinkimbinkimbi eklanyelwe ukulawula inqubo yokuguqulwa kwamandla. Ilawula ukusebenza kwamanje kanye ne-voltage, ivimbela ukushisa ngokweqile nokwelula isikhathi sokuphila sama-LED. Ama-algorithms athuthukisiwe ohlelweni lokulawula akhulisa ukusetshenziswa kwamandla, okwenza umshini usebenze kahle kakhulu. Lesi sici sibaluleke kakhulu ezinhlelweni ezizwelayo amandla njengezikhungo zedatha, lapho ukwethembeka nokusebenza kahle kubaluleke kakhulu.
- Ukuguqulwa kwamandla: Umshini uguqula kahle amandla kagesi abe ukukhanya, inqubo eshunwe kahle ukuze kwandiswe ukukhanya kuyilapho unciphisa ukumosheka kwamandla. Lokhu kufinyelelwa ngokuvumelanisa ngokunembile ukusebenza kwama-LED angawodwana. I-control circuitry iqinisekisa ukuthi i-LED ngayinye isebenza ngezimo ezifanele, okuholela kumthombo wokukhanya osebenza kahle futhi onokwethenjelwa.

Izicelo Ezindaweni Ezihlukahlukene

Ukuguquguquka komshini we-PDT LED kudlulela ngalé kokukhanya nje, okuwenza ube ithuluzi elibalulekile ezimbonini ezihlukahlukene.
- Ukulawula Ukukhanyisa: Ikhono layo lokulungisa ukukhanya nombala liyenza ilungele izinhlelo zokusebenza zokukhanyisa ezimbonini, ithuthukisa kokubili ukuphepha nokusebenza kahle. Umshini ungahlelwa ukuthi uvumelane nezimo ezihlukahlukene, njengokushintsha amaleveli okukhanya ngokusekelwe kokuhlala noma isikhathi sosuku.
- Izikhungo Zedatha: Ezindaweni ezinamandla amakhulu, lapho ukuthembeka nokusebenza kahle kubalulekile, umshini we-PDT LED uyaphumelela. Ingakwazi ukubhekana nezidingo zamandla ezidingekayo zezikhungo zedatha kuyilapho igcina ukusebenza okuphezulu. Ukulawula ukunemba kuqinisekisa ukuthi yonke i-LED isebenza kahle kakhulu, inciphisa ukukhiqizwa kokushisa nokumoshakala kwamandla.
- Imifanekiso Yezokwelapha: Ukulawula okunembile komshini phezu kokukhanya kunenzuzo ezinhlelweni zezokwelapha. Isibonelo, emfanekisweni we-fluorescence, lapho isilawuli sokukhanya esinembile sibalulekile ngezinjongo zokuxilonga, umshini we-PDT LED unganikeza amandla adingekayo nokulawula amaza. Lokhu kuthuthukisa ukunemba kokuxilonga nokwelashwa, kukwenze kube ithuluzi elibalulekile ekunakekelweni kwezempilo kwesimanje.

Izinselele kanye Nezitayela Zesikhathi esizayo

Naphezu kwezinzuzo zayo eziningi, umshini we-PDT we-LED ubhekana nezinselele ezimbalwa ekusebenziseni okungokoqobo.
- Ukuphathwa Kwezishisayo: Enye yezinselelo ezinkulu ukuphatha ukukhiqizwa kokushisa. Ama-LED akhiqiza ukushisa ngesikhathi sokusebenza, futhi umshini kufanele uvimbele ukushisa ngokweqile ukuze ulondoloze ukusebenza futhi wandise isikhathi sokuphila sama-LED. Amasu amasha obuchwepheshe bokukhipha ukushisa abalulekile ekunqobeni lesi sithiyo.
- Ukusebenza Kwezindleko: Nakuba ukutshalwa kwezimali kokuqala emshinini we-PDT LED kungase kube phezulu uma kuqhathaniswa nezinhlelo zokukhanyisa ezivamile, ukonga izindleko okuqhubekayo nokusebenza kahle kwamandla kungavala lezi zindleko zokuqala. Kodwa-ke, ukunciphisa izindleko nokuthuthukisa ukusebenza kuyimigomo eqhubekayo yabakhiqizi.

Isiphetho

Ukukufingqa, umshini we-PDT LED uyisibonelo esihle sobuchwepheshe obuthuthukisiwe obusebenza. Isebenza kusukela ekuthuthukiseni izindawo zokukhanyisa kuya ekusizeni ukwelashwa. Njengoba siqhubekela phambili, umshini we-PDT LED uzoqhubeka nokubumba kabusha ikusasa lobuchwepheshe bokukhanya nokuguqulwa kwamandla.
Sengiphetha, umshini we-PDT LED iyithuluzi eliphawulekayo elihlanganisa ukunemba nokusebenza kahle, okwenza kube okuvelele emkhakheni wobuchwepheshe be-LED. Ukuguquguquka kwayo nokusebenza kwayo kuyenza ibe yimpahla ebalulekile ezimbonini ezihlukahlukene, futhi intuthuko eqhubekayo ithembisa ukuthuthukisa amakhono ayo nakakhulu.
