Ukwelashwa kokukhanya kwe-LED kusebenza kanjani futhi yiziphi izibani zamaza ezibalulekile?

Ukwelashwa ngokukhanya kwe-LED kuncike esimisweni sokuthi amaza athile okukhanya angamuncwa amaseli futhi abangele izimpendulo zezinto eziphilayo. Isikhumba nezinye izicubu ziqukethe ama-chromophores, ama-molecule amunca ukukhanya kumaza athile. Lapho la ma-chromophores amunca ama-photon, abhekana nezinguquko ezingathinta imetabolism yamaseli, izindlela zokubonisa izimpawu, kanye nokubonakaliswa kwezakhi zofuzo. Ama-chromophores amabili avame ukuxoxwa ngawo yi-cytochrome c oxidase kuma-mitochondria kanye ne-melanin kumaseli akhiqiza umbala; lawa kanye namanye ama-chromophores anquma ukuthi amaza ahlukene awuthinta kanjani umzimba.

Ukukhanya okubomvu nokuseduze kwe-infrared (NIR) yiwona maza amakhulu asetshenziswa kumaphaneli okwelapha. Ukukhanya okubomvu, ngokuvamile okuphakathi kwama-nanometer angu-620 kuya kwangu-700, kungena ku-epidermis kanye nengxenye ye-dermis futhi kuvame ukuhlotshaniswa nemiphumela efana nokukhuthaza ukukhiqizwa kwe-collagen, ukuthuthukisa ithoni yesikhumba, kanye nokunciphisa ukuvuvukala. Ukukhanya okuseduze kwe-infrared, okuvame ukuba phakathi kwama-nanometer angu-800 kuya kwangu-880, kungena ngokujulile ezicutshini futhi kungafinyelela izakhiwo ezingaphansi kwesikhumba, okwenza kube okubaluleke kakhulu ekuvuseleleni imisipha, ukuqeda ubuhlungu bamalunga, kanye nokuthuthukisa ukujikeleza kwegazi. Ukukhanya okuluhlaza okwesibhakabhaka, okuphakathi kwama-nanometer angu-415 kuya kwangu-450, kunesenzo esihlukile: kumuncwa kakhulu ama-porphyrins akhiqizwa amabhaktheriya abangela i-acne futhi kunganciphisa umthwalo wamagciwane esikhumbeni, okwenza kube usizo ekulawuleni i-acne. Kukhona futhi izinhlobo eziluhlaza neziphuzi ezithengiswayo zokulawula umbala kanye nokuzola isikhumba, kodwa ubufakazi bezokwelapha balokhu abuqinile kangako kunobomvu, i-NIR, kanye nohlaza okwesibhakabhaka.

Ubukhulu kanye nomthamo wamandla kubalulekile njengobude besikhathi. Ubukhulu bokukhanya (ukukhazimula) kulinganiswa ngama-milliwatts ngesentimitha lesikwele, futhi amandla aphelele alethwayo avame ukuvezwa njengama-joules ngesentimitha lesikwele. Kokubili kuthinta izinga lokuvuselelwa kwamaseli. Amandla amancane kakhulu angase angabi namphumela obonakalayo, kuyilapho amaningi kakhulu anganciphisa ukusebenza kahle noma akhiqize ukushisa ngaphandle kwenzuzo eyengeziwe yokwelapha. Ukukhishwa kwamagagasi okucindezelayo ngokumelene nokuqhubeka kungenye into eguquguqukayo; amanye amadivayisi ashaya ukukhanya ukuze avumele izicubu ukuba ziphumule phakathi kokuqhuma, okungase kuthonye imiphumela kwezinye izindlela.

Ukuqonda ukusebenzisana kobude be-wavelength, ukuqina, kanye nobude bokwelashwa kubalulekile. Ukuze kubuyiselwe isikhumba, ukukhanya okubomvu okunamandla aphansi okusetshenziswa isikhathi eside kungakhuthaza ukuvuselelwa kwe-collagen. Ukuze kutholakale izicubu ezijulile, i-NIR enamandla aphezulu enezikhathi ezimfushane ingakhethwa. Ukwelashwa kokukhanya okuluhlaza okwesibhakabhaka kwama-acne ngokuvamile kudinga imithamo elawulwayo kanye nokunaka ukuphepha kwamehlo njengoba ubude be-wavelength obuluhlaza busakazeka kakhulu ezicutshini futhi kungathinta i-retina. Ekugcineni, lapho uhlola iphaneli, funa imininingwane ecacile ngama-wavelength asetshenzisiwe, ukukhanya okukhanyayo ebangeni elithile, kanye nezikhathi zokwelapha ezinconywayo, ngoba lezo zibalo zinquma imiphumela yezinto eziphilayo ongayilindela.

Ukwelashwa kokukhanya kwe-LED kusebenza kangakanani ezimweni zesikhumba futhi yimiphi imiphumela ongayilindela?

Ukusebenza kahle kokwelashwa kokukhanya kwe-LED kuyahlukahluka kuye ngesimo eselashwayo, ubude bamaza asetshenziswayo, kanye nokunamathela ohlelweni lokwelashwa olufanele. Ngezinkinga eziningi ezihlobene nesikhumba, kunobufakazi obuhloniphekile obusekela ukuthuthuka okunenjongo, yize izimpendulo zomuntu ngamunye zingahluka. Lapho okulindelwe kungokoqobo futhi kulandelwa izinqubo, ukwelashwa kwe-LED kuvame ukukhiqiza izinzuzo eziqhubekayo kancane kancane kunezinguquko ezisheshayo.

Ukuze kubuyiselwe isikhumba, ukwelashwa ngokukhanya okubomvu kuphakathi kwezicelo ezisekelwa kakhulu. Izifundo kanye nokuhlangenwe nakho kwezokwelapha kubonisa ukuthi izikhathi eziqhubekayo emavikini amaningana zingandisa ukuminyana kwe-collagen, zinciphise imigqa emincane kanye nemibimbi, futhi zithuthukise ukuthungwa kwesikhumba kanye nethoni. Ukuthuthuka kuvame ukubonwa ngemva kwamasonto ambalwa okusetshenziswa njalo—ngokuvamile cishe amasonto amane kuya kwayisishiyagalombili—futhi kuqhubeke nokuqongelela ngokwelashwa okuqhubekayo. Imiphumela incane futhi iyaqhubeka; ukukhanya okubomvu kanye ne-NIR akunikezi ukuqina okukhulu kwezinqubo ezihlaselayo, kodwa kukhuthaza isikhumba esinempilo nesiqinile futhi kungahambisana nezinye izindlela ezifana ne-retinoids noma i-microneedling.

Ngezinduna, ukwelashwa ngokukhanya okuluhlaza okwesibhakabhaka kube yimpumelelo ekunciphiseni ukuqubuka kokuvuvukala ngokugxila kuma-porphyrins ebhaktheriya, kuyilapho ukukhanya okubomvu kungasiza ukuzola ukuvuvukala nokusekela ukuphulukiswa. Izinqubo ezihlanganisiwe eziluhlaza okwesibhakabhaka nokubomvu zivame ukusetshenziswa emitholampilo namadivayisi asekhaya ukubhekana nomthwalo wamagciwane kanye nempendulo yokuvuvukala. Iziguli zivame ukubona ukuqubuka okuncane nokungathí sina ngemva kwamasonto ambalwa, futhi ukusetshenziswa okuqhubekayo kunganciphisa ukuphindaphinda kwabantu abaningi. Kodwa-ke, izinduna ezithonywe ama-hormone noma izici zomzimba zingadinga ukwelashwa okwengeziwe kwezokwelapha.

Ukushintshashintsha kombala kanye nokushintsha kombala kusabela ngokuguquguquka. Amanye ama-wavelength abizwa ngokuthi “luhlaza” noma “ophuzi” athengiswa ngokushintshashintsha kombala, kodwa ukuvumelana kwesayensi akunamandla kangako kunokukhanya okubomvu nokuluhlaza okwesibhakabhaka. Kwezinye izimo, ukwelashwa kokukhanya kungathuthukisa ukubonakala kokushintshashintsha kombala ngemva kokuvuvukala ngokushintshashintsha kokuvuvukala kanye nokuguquka kwamaseli, kodwa imiphumela ngokuvamile iyancipha futhi incane.

Ukuze kuphulukiswe amanxeba kanye nokunciphisa izibazi, i-NIR kanye nokukhanya okubomvu kubonise imiphumela ethembisayo ekukhuthazeni ukulungiswa kwezicubu, ukuthuthukisa ukujikeleza kwegazi, kanye nokunciphisa ukujiya kwezibazi ngokuhamba kwesikhathi. Ukululama kwezemidlalo kanye nokuqeda ubuhlungu nakho kuyazuza kumaza e-NIR angena ngokujulile, akhuthaza ukujikeleza kwegazi okuncane kanye nokunciphisa ukuvuvukala. Abasubathi bavame ukubika izikhathi zokululama ezisheshayo kanye nobuhlungu obuncane ngemva kwezikhathi ze-NIR eziqondiwe.

Kubalulekile ukulawula okulindelwe: Ukwelashwa nge-LED akuyona ikhambi lazo zonke izinto. Imiphumela emihle kakhulu ivela ekusetshenzisweni njalo kanye nokunakekelwa kwesikhumba okuhle, imikhuba yokuphila, futhi, uma kufaneleka, ukwelashwa okwengeziwe. Uma ulandela izinqubo ezinconywayo—amaza okukhanya afanele, ukukhanya okwanele, kanye nokuhlela okuqhubekayo—ungalindela izinzuzo zobuhle nokusebenza kancane kancane, yize isikhathi kanye nobukhulu kuzohluka kumuntu nomuntu.

Ingabe ukwelashwa ngokukhanya kwe-LED kuphephile, futhi yiziphi izingozi noma iziphazamiso ezingaba khona?

Sekukonke, ukwelashwa ngokukhanya kwe-LED kubhekwa njengokwelashwa okunengozi ephansi, okungangenisi ingozi uma kuqhathaniswa nama-laser kanye nezinqubo eziningi zesikhumba ezihlaselayo. Ngenxa yokuthi ama-LED akhipha ukukhanya okungeyona i-ionizing, awathwali izingozi ezifanayo zomonakalo we-DNA ohlotshaniswa nemisebe ye-ultraviolet. Lokho kusho ukuthi, ukuphepha kuncike ekusetshenzisweni okufanele, ikhwalithi yedivayisi, kanye nezici ezithile zesiguli. Ukuqonda izingozi ezaziwayo kanye neziphambeko kusiza abasebenzisi ukuthi benze izinqumo ezinolwazi futhi bagweme izinkinga ezingavinjelwa.

Imiphumela emincane evame kakhulu ingeyesikhashana futhi ifaka phakathi ukubomvu, ukuqina okuncane, noma ukucasuka kwesikhashana ngokushesha ngemva kokwelashwa, ikakhulukazi uma kunamandla aphezulu noma uma kusetshenziswa kaningi. Amehlo angaba nomuzwa wokukhanya okukhanyayo, futhi ukuchayeka ngokungavikelekile ekukhanyeni okuluhlaza okwesibhakabhaka noma okuseduze ne-infrared kungase kungakhululeki; amaphaneli amaningi eza noma ancoma izibuko. Abantu abazwela ukukhanya—kungaba ngenxa yemithi efana nama-antibiotic athile, ama-retinoids, noma izithasiselo zamakhambi, noma izimo ezingaphansi njenge-lupus—kufanele babonisane nochwepheshe wezempilo ngaphambi kokuqala ukwelashwa. Ama-photosensitizing agents andisa ingozi yokucasuka kwesikhumba noma ukusabela okubi uma kuhlanganiswa nokuchayeka ekukhanyeni.

Amanye amadivayisi akhiqiza ukushisa noma ukukhanya okunamandla okungadala izimo zibe zimbi kakhulu uma kusetshenziswa kabi. Ukuchayeka ngokweqile—ukukhanya okukhulu kakhulu uma useduze noma ukuvezwa isikhathi eside kakhulu—kungaholela ekushiseni noma ekuvuvukeni okukhulu, yize imiphumela enjalo ingavamile ngamaphaneli ekhwalithi aklanyelwe ukusetshenziswa ngabathengi. Landela njalo imiyalelo yomkhiqizi mayelana nebanga, ubude besikhathi, kanye nokuchayeka okuvamile masonto onke.

Kunezimo ezithile eziphikisana nezokwelapha okufanele uziqaphele. Abantu abanomdlavuza wesikhumba osebenzayo noma izilonda ezisolisayo akufanele bazenzele lezo zindawo ngaphandle kwemvume yezokwelapha. Abantu abanesifo sokuwa okubangelwa ukukhanya okukhanyayo bangase babe sengozini ngamadivayisi asebenzisa ukukhanya okushukunyiswa yi-pulsed; amadivayisi aqhubeka nokukhanya ngokuvamile aphephile ezimweni ezinjalo. Abantu abakhulelwe bavame ukwelulekwa ukuthi bafune iseluleko sezokwelapha ngaphambi kokuqala ukwelashwa okusha, yize ukukhanya okubomvu kanye nokukhanya kwe-NIR okusetshenziswa esikhumbeni ngokuvamile kubhekwa njengengozi ephansi uma kungafakwanga ngqo esiswini; noma kunjalo, isiqondiso sochwepheshe siwukuhlakanipha.

Amadivayisi athile afakelwa noma imithi ezwela ukukhanya adinga ukuqaphela. Nakuba ukukhanya kwe-LED ngokuvamile kungaphazamisi i-pacemaker noma i-implants, noma ubani onamadivayisi kagesi afakelwe kufanele axoxe ngokusetshenziswa nodokotela wakhe. Ngaphezu kwalokho, ochwepheshe bobuhle ngezinye izikhathi bacebisa ukuqaphela lapho behlanganisa ukwelashwa kokukhanya nezinqubo ezinciphisa isikhumba noma ezinciphisa isithiyo saso okwesikhashana, njengezikhumba zamakhemikhali ezinamandla, kuze kube yilapho isikhumba sesipholile.
