Uninzi lwabantu luyazi ukuba ukukhanya kunokubola kuthotho lokukhanya kwe-monochromatic ngokusasazeka.I-spectrum yibhanti yokukhanya apho ukukhanya okuntsonkothileyo kusasazwa yinkqubo ye-dispersive system (umz., iiprism, iigratings) kwaye emva koko ibole ibe luluhlu lokukhanya kwe-monochromatic, olucwangciswe ngokulandelelana kwe-wavelength.

Nangona kunjalo, ukukhanya okwahlukileyo kwi-spectrum kunokuhanjiswa kwamandla okwahlukileyo, i-wavelengths eyahlukeneyo yokubunjwa komlinganiso iya kwahluka.Ukukhanya kwelanga kunomlinganiselo obanzi kakhulu oqhubekayo, i-99.9% yamandla igxininiswe kwimimandla ye-infrared, ebonakalayo kunye ne-ultraviolet.

Izibane zokukhanyisa "kwi-full spectrum", zibhekisela ekukhanyeni okuphuma kwizibane kunye nezibane, i-spectrum isondele kwi-spectrum yelanga, ngokukodwa kwinxalenye ebonakalayo ye-wavelengths ehlukeneyo ngomlinganiselo wamacandelo afana nokukhanya kwelanga, ukukhanya. yesalathiso sombala sisondele kwisalathiso sombala sokukhanya kwelanga.

Enyanisweni, izibane ezipheleleyo azizange zibe ntsha ixesha elide;bekukho imithombo yokukhanya yenqanaba elipheleleyo ixesha elide.Kulungile, isizukulwana sokuqala semithombo yokukhanya yombane - izibane ze-incandescent.Umgaqo wokukhanya kwe-incandescent udlula kwi-voltage yangoku ukuya kwi-tungsten filament "evuthayo" eshushu, ukuze itshise i-incandescent ekukhanyeni.Ngenxa yokuba i-spectrum yokukhanya kwe-incandescent iyaqhubeka kwaye igubungela ummandla obonakalayo, ngoko izibane ze-incandescent zinesalathiso sombala ophezulu, zinokukhanyiswa ukuze zibonise umbala wokwenene.

Nangona kunjalo, ngenxa yokusebenza okuphantsi kokukhanya okukhanyayo kwezibane ze-incandescent kunye nobomi obufutshane beentsilelo ezimbini ezibulalayo ezinkulu zezibane ze-incandescent zikhokelela kwizibane ze-incandescent, "indleko", nokuba umbala okhanyayo ulungile kakhulu izibane ze-incandescent ziye zatshintshwa yisizukulwana esitsha. imithombo yokukhanya okuluhlaza.

Kwiminyaka yakutshanje, uphuhliso lwempumelelo ye-LED, ukwaphula isithintelo setekhnoloji engundoqo, abantu baya kuba yiblue LED excitation phosphor yetekhnoloji yemveli ye-LED ukuya kuthi ga kusetyenziso lwe-violet LED excitation phosphor ukufumana ukukhanya okubomvu, okuluhlaza kunye nombala oluhlaza okwesibhakabhaka, emva kombala. Ukukhanya okuxutywayo kunyanzeliswe ukuvelisa kunye nemitha yelanga yokukhanya okufanayo.

Le teknoloji idityaniswe neempawu zobugcisa ze-LED kunye neenzuzo zemveliso, okwenza i-LED egcweleyo ihambelane neemfuno kunye neendlela zemarike yokukhanyisa, ngoko ke i-LED egcweleyo iyathandwa kakhulu.

Emva kokuqonda intsingiselo kunye nesizukulwana se-spectrum epheleleyo, ndicinga ukuba sonke sinombono we-spectrum epheleleyo.Kodwa i-spectrum epheleleyo yale teknoloji kumsebenzisi kwaye luhlobo luni lweenzuzo, nokuba ngaba abathengi bathenge ukuthenga? 

Ukukhanya okunempilo

Impembelelo kwimpilo yabantu

Ngaphambi kokuba kubekho imithombo yokukhanya eyenziwe ngabantu, ukukhanya kwelanga kwakukuphela komthombo wokukhanya, yaye ookhokho bethu babexhomekeke elangeni ukuze baziphilise.Ukukhanya kwelanga akupheleli nje ekuboneleleni umhlaba ngomthombo wokukhanya namandla, kodwa ukukhanya kwelanga kukwalawula isingqi somzimba womntu kwaye kunempembelelo kwibhayoloji yomntu, kwingqondo nakumzimba womntu.

Nangona kunjalo, abantu basezidolophini bale mihla, ingakumbi abasebenzi baseofisini, bachitha ixesha elide bengaphakathi ezindlwini yaye abafane badibane nokukhanya kwelanga, yaye abakwazi ukufumana izibonelelo zempilo elangeni.Ukubaluleka kombala ogcweleyo kukuvelisa kwakhona ukukhanya kwelanga kwaye kusibuyisele kuthi inzuzo yefiziyoloji, yengqondo, kunye nomzimba womntu wokukhanya kwendalo okusebenza ebantwini. 

Numbala wendalo

Sonke siyazi ukuba into iya kubonisa umbala wayo xa ibonakaliswe ekukhanyeni, kodwa xa into ibonakaliswe kumthombo wokukhanya kunye ne-spectrum engaqhubekiyo kunye ne-spectrum engaphelelanga, umbala uya kugqwetheka kumazinga ahlukeneyo.IKomishoni yaMazwe ngaMazwe yoKhanyiso lweCIE kumthombo wokukhanya kwinto yombala oyinyani weqondo lokuboniswa kwenkcazelo yomthombo wokukhanya wonikezelo lombala.Ukuze uchaze ngokulula ngakumbi unikezelo lombala womthombo wokukhanya, kodwa kwakhona wazisa ingqikelelo yonikezelo lwesalathiso sombala, ngokusekwe kumthombo wokukhanya osemgangathweni, isalathiso sonikezelo sombala uRa simiselwe kwi-100.

Ngaba uninzi lweemveliso ze-LED zangoku ziye zakwazi ukwenza isalathisi sombala we-Ra> 80, kodwa kwezinye izicelo kwi-studio, studio, njl. , Umbala wenyama entsha i-reproducible scenarios, isalathisi esinikezela ngombala jikelele u-Ra akakwazanga ukwanelisa ukuvavanya amandla omthombo wokukhanya ukubuyisela umbala oyinyaniso.

Ngoko ke ukuvavanya amandla omthombo wokukhanya ukubuyisela umbala kokulungileyo okanye okubi akunakusekelwa kuphela kwisalathiso sombala jikelele wonikezelo ukuze sigwebe, kwimiboniso ekhethekileyo, sinokudinga kwakhona ukuqwalasela umthombo wokukhanya wesalathiso sombala okhethekileyo. I-R9, i-color saturation Rg, kunye nokunyaniseka kombala wexabiso le-Rf.Ukukhanya kwezibane ezigcweleyo kunombala wokukhanya kwebhanti nganye ye-wavelength kummandla obonakalayo weso lomntu, onokunika ingqiqo ecebileyo yombala kunye nokubuyisela eyona mibala yendalo kunye neyenyani yezinto ezikhanyisiweyo.

Ngaphandle koko, ukusebenza ixesha elide kwindawo yokusebenza ngokungabikho kombala kunye nethoni enye, abantu bathambekele ekudinweni okubonakalayo kunye noxinzelelo lwengqondo.I-spectrum ecebileyo yokukhanya okugcweleyo inokuvelisa umbala wangempela wento, inike ukukhanya okucacileyo, ikhuphe ukudinwa okubonakalayo kweliso lomntu, ukunciphisa ukungahambi kakuhle kwamehlo, kwaye ngaloo ndlela iphucule induduzo yendawo yokukhanya komsebenzisi.

Ukunyamekela amehlo akho

Kuba uninzi lwee-LED zemveli zisebenzisa ukukhanya okuluhlaza ukonwabisa iphosphor etyheli kunye nokuxuba ukukhanya kombala ukufumana ukukhanya okumhlophe.Ukuba icandelo lokukhanya okuluhlaza okwesibhakabhaka liphezulu kakhulu, kwimeko yokusetyenziswa ixesha elide, ukukhanya okuluhlaza okwesibhakabhaka kunokungena kwi-lens yeso lomntu kwi-retina, kukhawulezise i-oxidation yeeseli ze-macular, ezibangela umonakalo optical.

Kwiliso lomntu, abantu emva kwexesha elide lokuziphendukela kwemvelo, iliso lomntu liziqhelanise nokukhanya kwelanga, ukukhanya kufutshane nokukhanya kwendalo, ngakumbi iliso lomntu liziva likhululekile.I-LED ye-Spectrum epheleleyo ithatha i-violet LED excitation, enciphisa icandelo lokukhanya okuluhlaza okwesibhakabhaka ukusuka kwingcambu yomthombo wokukhanya ukunciphisa umonakalo wamehlo.

Ngelo xesha, i-spectral curve ye-spectrum epheleleyo isondele kwi-curve ye-spectral yelanga, enokuphucula ngokufanelekileyo induduzo yamehlo omsebenzisi.Ukongeza, i-spectrum epheleleyo inokunciphisa i-retinal microcirculation imiqobo yexesha elifutshane, kunye nokucothisa imiqobo yokubonelela ngegazi okubangelwa ukomisa kwamehlo kunye nokukhathala, ukuze kuphunyezwe ukukhuselwa kwamehlo okwenyani.

Lungisa umsebenzi wakho wesiqhelo

Ngokomthetho wewotshi yebhayoloji yomntu, ingqondo yomntu idla ngokuqalisa ukukhupha imelatonin ngentsimbi yesi-9 okanye eye-10 ebusuku Njengoko imelatonin engakumbi ikhutshwa lidlala lobuchopho bomntu, ngokuthe ngcembe umzimba wethu uye uqonde ukuba kufuneka uphumle kwaye ulale.I-Melatonin yinto enceda ukunciphisa ixesha lokuvuka ngaphambi kokulala kunye nexesha lokulala, elinokuphucula umgangatho wokulala.Kwaye le nto inobudlelwane obusondeleyo kunye nokukhanya okubonakaliswa ngabantu, ngokukodwa ukukhanya okuluhlaza okwesibhakabhaka, ukukhanya okuluhlaza okwesibhakabhaka kuya kuba nefuthe elithintelayo kwi-melatonin eveliswa yi-pineal gland yobuchopho bomntu, ixesha elide ekukhanyeni okuluhlaza okwesibhakabhaka. indawo ekhanyayo, kwaye ivelisa ukuphazamiseka kokulala.

Kwaye ukuvela kwe-spectrum epheleleyo kunokubonelela ngokukhanya okusemgangathweni kunye nokuphucula indawo yokukhanya yobomi babantu.Amacandelo ambalwa okukhanya okuluhlaza okwesibhakabhaka anokwenza indawo yokukhanya esebenzayo yasebusuku ibe nengqiqo ngakumbi, kwaye indawo yokukhanya efanelekileyo inokunceda abantu bakhuthaze ukulala, bakhulise imveliso kunye nokuphucula isimo sengqondo.

Ukuba inkqubo yokukhanyisa i-spectrum epheleleyo inokudibaniswa kunye nokulinganisa kokutshintsha kombala welanga wokushisa unyaka wonke kunye namaxesha ahlukeneyo emini nasebusuku, ukubonelela ngakumbi njengokukhanya kwendalo kwangempela.Ukudityaniswa kwezi zimbini kuya kuhambisa ngokwenene ukukhanya kwelanga kwindlu yangaphakathi, ukuze "bangaliboni ilanga" abasebenzi banokuziva bekhululekile ukukhanya kwelanga ngaphandle kokushiya ikhaya.

Okwangoku, i-spectrum epheleleyo isekho kwinqanaba elikhulayo, ngenxa yokuba ixabiso layo liphezulu xa lithelekiswa ne-LED eqhelekileyo, ngokuthintelwa kwexabiso, ngoko ke i-spectrum epheleleyo ye-LED ye-market share kwi-market market ibalwa njengenxalenye encinci kakhulu.Kodwa ngokuphuculwa kwetekhnoloji kunye nokwazisa kokukhanya kokuthandwa, ndiyakholelwa ukuba kuya kubakho abasebenzisi abaninzi abakuqondayo ukubaluleka komgangatho ogcweleyo kwaye bakhethe ukusebenzisa izibane ezigcweleyo kunye neemveliso zezibane, iinkampani zokukhanyisa ziya kusekelwa kwiimfuno imakethi ukwenza iimveliso ezibalaseleyo ezigcweleyo.
