Ngenxa yempembelelo ebalulekileyo yokukhanya okusingqongileyo kwimpilo yabantu, i-photohealth, njengentsimi evelisa izinto ezintsha kwishishini lezempilo elikhulu, iya isanda kakhulu kwaye ibe yimarike evelayo yehlabathi. Iimveliso zempilo ezikhanyayo ziye zasetyenziswa ngokuthe ngcembe kumacandelo ahlukeneyo afana nokukhanya, ukhathalelo lwempilo, unyango kunye neenkonzo. Phakathi kwabo, ukukhuthaza "ukukhanya okunempilo" ukuphucula umgangatho wokukhanya kunye nokuthuthuzela kunokubaluleka okubonakalayo, kunye nobukhulu bemarike obudlula i-yuan yetriliyoni enye.
I-spectrum epheleleyo ibhekiselele ekufaniseni ukukhanya kwendalo (kunye nobushushu obufanayo bombala) kunye nokususa i-ultraviolet eyingozi kunye nemitha ye-infrared ekukhanyeni kwendalo. Xa kuthelekiswa nokukhanya kwendalo, ingqibelelo yoluhlu olupheleleyo isondele ekufaniseni ukukhanya kwendalo. I-LED ye-spectrum epheleleyo inciphisa ukukhanya okuluhlaza okwesibhakabhaka xa kuthelekiswa ne-LED eqhelekileyo, iphucula ukuqhubeka kwebhendi yokukhanya ebonakalayo, kwaye iphucula ngokufanelekileyo umgangatho wokukhanya kwe-LED. Ithiyori ephambili yempilo yokukhanya kukuba "ukukhanya kwelanga kokona kukhanya okunempilo", kwaye iitekhnoloji zayo ezintathu ezingundoqo ziyinhlanganisela esebenzayo yekhowudi yokukhanya, ifomula yokukhanya, kunye nokulawula ukukhanya, okwenza ukubonakaliswa kweenzuzo ezifana nokugcwala kombala, ukuzala kombala, kunye nokukhanya okuluhlaza okuphantsi kwimiboniso yokukhanyisa. Ngokusekwe kwezi zibonelelo, i-LED ye-spectrum epheleleyo ngokungathandabuzekiyo ngowona mthombo wokukhanya owenziweyo ufanelekileyo kwiimfuno "zezempilo ezikhanyayo" okwangoku.
Okubaluleke ngakumbi, impilo ekhanyayo inokuphinda ichaze kwakhona ukukhanya okugcweleyo. Nangona i-spectrum epheleleyo esixoxa ngayo ngoku kwintsimi yokukhanyisa kwe-LED ikakhulu ibhekiselele kwi-spectrum epheleleyo yokukhanya okubonakalayo, oku kuthetha ukuba umlinganiselo wecandelo ngalinye le-wavelength ekukhanyeni okubonakalayo ufana nokukhanya kwelanga, kunye nesalathiso sombala wokunikezela. Ukukhanya kokukhanya kusondele koko kukhanya kwelanga. Ngophuhliso oluqhubekayo lwetekhnoloji kunye nemfuno yentengiso, ulwalathiso lophuhliso lwexesha elizayo lwe-LED egcweleyo ngokuqinisekileyo lulungelelaniswa nokukhanya kwelanga, kubandakanya indibaniselwano yembonakalo yokukhanya engabonakaliyo. Ayinakusetyenziswa kuphela ekukhanyeni, kodwa nakwintsimi yempilo ekhanyayo, kwaye ingasetyenziselwa ngokubanzi kwiinkalo ezifana nempilo elula kunye neyeza elilula.

Izibane ezigcweleyo ze-LED zifaneleke ngakumbi kwimiboniso efuna ukumelwa kombala ochanekileyo. Xa kuthelekiswa nee-LED eziqhelekileyo, ii-LED ze-spectrum ezigcweleyo zinoluhlu olubanzi lwamathemba okusebenza. Ukongeza kokusetyenziswa ekukhanyeni kwezemfundo, izibane zetafile zokukhusela amehlo, kunye nokukhanya kwekhaya, zinokusetyenziswa nakwiindawo ezifuna umgangatho ophezulu we-spectral, njengezibane zokuhlinzwa, izibane zokukhusela amehlo, ukukhanya kwemyuziyam, kunye nokukhanya kwendawo ephezulu. Nangona kunjalo, emva kweminyaka yokulima kwimarike, iinkampani ezininzi ziye zangena ekukhanyeni okugcweleyo kwezempilo, kodwa ukuthandwa kweemarike zokukhanya okugcweleyo akukabi phezulu, kwaye ukunyusa kusenzima. Ngoba?
Kwelinye icala, itekhnoloji ye-spectrum epheleleyo yeyona teknoloji yesicelo sokukhanyisa impilo, kwaye iinkampani ezininzi ziyithatha njenge "BMW". Ixabiso layo alifikeleleki kwaye kunzima kubathengi abaninzi ukuba bamkele. Ngokukodwa, imarike yokukhanyisa yangoku inomgangatho wemveliso ongalinganiyo kunye namaxabiso ahlukeneyo, okwenza kube nzima kubathengi ukwahlula kunye nokuphenjelelwa lula ngamaxabiso. Ngakolunye uhlangothi, uphuhliso loshishino lokukhanyisa olunempilo luye lwacotha, kwaye ishishini elikhuthazwayo kwiimarike lisakhula.
Okwangoku, i-LED ye-spectrum epheleleyo isekho kwinqanaba elikhulayo, njengoko ixabiso layo liphezulu okwethutyana kune-LED eqhelekileyo, kwaye ngenxa yokunyanzeliswa kwexabiso, isabelo semarike ye-LED epheleleyo kwimarike yokukhanyisa incinci kakhulu. Kodwa ngokuphuculwa kwetheknoloji kunye nokuthandwa kolwazi lokukhanyisa impilo, kukholelwa ukuba abasebenzisi abaninzi baya kuqonda ukubaluleka komgangatho wokukhanya kwemveliso yokukhanyisa i-spectrum epheleleyo, kwaye isabelo sabo semarike siya kukhula ngokukhawuleza. Ngaphezu koko, iskimu sokukhanyisa esidibanisa i-LED egcweleyo kunye nolawulo oluhlakaniphile lunokusetyenziswa ngcono kwiimeko ezahlukeneyo, ukuxhamla ngokupheleleyo kwiinzuzo ze-LED egcweleyo ekuphuculeni umgangatho wokukhanyisa kunye nokuphucula ukuqatshelwa kwabantu kokuthuthuzela ukukhanya.
