Abantu abaningi bayazi ukuthi ukukhanya kungabola kube uchungechunge lokukhanya kwe-monochromatic ngokuhlakazeka.I-spectrum iyibhande lokukhanya lapho ukukhanya okuyinkimbinkimbi kuhlakazwa isistimu ehlakazekayo (isb., amaprism, ama-gratings) bese iboliswa ibe uchungechunge lokukhanya kwe-monochromatic, ehlelwa ngokulandelana kwe-wavelength.

Kodwa-ke, ukukhanya okuhlukile ku-spectrum kunokusabalalisa kwamandla okuhlukile, ubude be-wavelength obuhlukahlukene bokubunjwa kwesilinganiso buzohluka.Ukukhanya kwelanga kune-spectrum ebanzi kakhulu eqhubekayo, u-99.9% wamandla ugxile ezindaweni ze-infrared, ezibonakalayo kanye ne-ultraviolet.

Izinto zokukhanyisa "ku-spectrum egcwele", kubhekisela ekukhanyeni okukhishwa izibani nezibani, i-spectrum iseduze ne-solar spectrum, ikakhulukazi engxenyeni ebonakalayo yamaza ahlukahlukene ahlukene ngesilinganiso sezingxenye ezifana nokukhanya kwelanga, ukukhanya. inkomba yokunikeza umbala iseduze nenkomba yokunikeza umbala yokukhanya kwelanga.

Eqinisweni, izibani ze-spectrum ezigcwele azikabi zintsha isikhathi eside;sekunemithombo yokukhanya enezinga eligcwele isikhathi eside.Kulungile, isizukulwane sokuqala semithombo yokukhanya kagesi - izibani ze-incandescent.Umgomo wokukhanya kwe-incandescent udlula ku-voltage yamanje ukuya ku-tungsten filament "evuthayo" eshisayo, ukuze ishe ifinyelele ekukhanyeni.Ngenxa yokuthi i-spectrum yokukhanya kwe-incandescent iyaqhubeka futhi ihlanganisa isifunda esibonakalayo, ngakho-ke amalambu e-incandescent anenkomba ephezulu yokunikeza umbala, angakhanyiswa ukuze abonise umbala wangempela.

Kodwa-ke, ngenxa yokukhanya okuphansi kokusebenza kahle kwezibani ze-incandescent nokuphila okufushane kokushiyeka okukhulu okubulalayo okubili kwezibani ze-incandescent kuholela ezibanini ze-incandescent, "ezibizayo", noma ngabe umbala okhanyayo uhle kakhulu izibani ze-incandescent zithathelwe indawo yisizukulwane esisha. imithombo yokukhanya eluhlaza.

Eminyakeni yamuva, ukuthuthukiswa kokuphumelela kwe-LED, ukwephula umgoqo wobuchwepheshe obalulekile, abantu bazoba i-phosphor ye-LED ye-blue yendabuko yobuchwepheshe bendabuko be-LED kuze kusetshenziswe i-violet LED excitation phosphor ukuze uthole ukukhanya kombala obomvu, oluhlaza okwesibhakabhaka, emva kombala. ukuxubana okukhanyayo okubekwe phezulu ukuze kukhiqizwe kanye nobubanzi belanga bokukhanya okufanayo.

Lobu buchwepheshe buhlanganiswe nezici zobuchwepheshe ze-LED kanye nezinzuzo zomkhiqizo, okwenza i-LED ye-spectrum egcwele ihambisane nezidingo kanye nokuthambekela kwemakethe yokukhanyisa, ngakho-ke i-LED ye-spectrum egcwele nayo ithandwa kakhulu.

Ngemva kokuqonda incazelo nesizukulwane se-spectrum egcwele, ngicabanga ukuthi sonke sinombono we-spectrum egcwele.Kodwa i-spectrum egcwele yalobu buchwepheshe kumsebenzisi nokuthi hlobo luni lwezinzuzo, kungakhathaliseki ukuthi kufanelekile abathengi ukuthenga? 

Ukukhanya Okunempilo

Umthelela empilweni yomuntu

Ngaphambi kokuba kube khona imithombo yokukhanya eyenziwe umuntu, ukukhanya kwelanga kwakuwukuphela komthombo wokukhanya, futhi okhokho bethu babethembele elangeni ukuze baziphilise.Akukhona nje kuphela ukuthi ukukhanya kwelanga kunikeza umhlaba umthombo wokukhanya namandla, kodwa ukukhanya kwelanga futhi kulawula isigqi sokuphila komuntu futhi kunomthelela kubhayoloji yomuntu, kwengqondo, kanye nomzimba womuntu.

Nokho, abantu basemadolobheni banamuhla, ikakhulukazi abasebenzi basemahhovisi, bachitha amahora amaningi besendlini futhi abavamile ukuthintana nokukhanya kwelanga, futhi abakwazi ukuthola izinzuzo zezempilo elangeni.Ukubaluleka kwe-spectrum egcwele ukukhiqiza kabusha ukukhanya kwelanga futhi ubuyisele kithi izinzuzo zomzimba, ezengqondo, nezomzimba womuntu zokukhanya kwemvelo okusebenza kubantu. 

Numbala wendawo

Sonke siyazi ukuthi into izobonisa umbala wayo lapho ivezwe ekukhanyeni, kodwa uma into ivezwa kumthombo wokukhanya one-spectrum engaqhubeki nengaphelele, umbala uzohlanekezelwa ngamadigri ahlukahlukene.I-International Commission on Illumination CIE emthonjeni wokukhanya entweni yombala wangempela wezinga lokwethulwa kwencazelo yomthombo wokukhanya wokunikezwa kombala.Ukuze uchaze kalula ukunikezwa kombala komthombo wokukhanya, kodwa futhi wethule umqondo wenkomba yokunikeza umbala, ngokusekelwe kumthombo wokukhanya ojwayelekile, inkomba yokunikeza umbala u-Ra isethwe kokuthi 100.

Kungaba iningi lemikhiqizo yamanje ye-LED ikwazile ukwenza inkomba yokunikeza umbala u-Ra>80, kodwa kwezinye izinhlelo zokusebenza ku-studio, studio, njll. kudingeka kube ukukhiqizwa kweqiniso kwezikhathi zombala wesikhumba, kanye nezithelo nemifino. , umbala wenyama entsha izimo ezikwazi ukukhiqizwa kabusha, inkomba evamile yokunikeza umbala u-Ra ayikwazanga ukwanelisa ukuhlolwa kwekhono lomthombo wokukhanya lokubuyisela umbala wangempela.

Ngakho-ke ukuhlola ikhono lomthombo wokukhanya lokubuyisela umbala wokuhle noma okubi akukwazi ukusekelwe kuphela kunkomba evamile yokunikeza umbala ukuze kwahlulelwe, ngezigcawu ezikhethekile, kungase kudingeke futhi sicabangele umthombo wokukhanya wenkomba ekhethekile yokunikeza umbala. I-R9, ukugcwaliswa kwesikhala kombala Rg, kanye nenani le-Rf le-color fidelity.Ukukhanya kwezibani ze-spectrum egcwele kunokukhanya kombala kwebhande le-wavelength ngalinye endaweni ebonakalayo yeso lomuntu, okunganikeza umqondo ocebile wombala futhi kubuyisele imibala yemvelo neyiqiniso kakhulu yezinto ezikhanyisiwe.

Ngaphandle kwalokho, ukusebenza isikhathi eside endaweni yokusebenza engenambala nethoni eyodwa, abantu bathambekele ekukhathaleni okubukwayo nokucindezela kwengqondo.I-spectrum ecebile yokukhanya kwe-spectrum egcwele ingakhiqiza kabusha umbala wangempela wento, inikeze ukukhanya okucacile, ikhulule ukukhathala okubonakalayo kweso lomuntu, inciphise ukungaphatheki kahle kwamehlo, futhi ngaleyo ndlela ithuthukise ukunethezeka kwendawo yokukhanya komsebenzisi.

Ukunakekela amehlo akho

Njengoba ama-LED amaningi endabuko esebenzisa ukukhanya okuluhlaza okwesibhakabhaka ukuze ajabulise i-phosphor ephuzi futhi axube ukukhanya kombala ukuze athole ukukhanya okumhlophe.Uma ingxenye yokukhanya okuluhlaza okwesibhakabhaka iphezulu kakhulu, esimweni sokusetshenziswa isikhathi eside, ukukhanya okuluhlaza okwesibhakabhaka kungangena kwi-lens yeso lomuntu ku-retina, kusheshise i-oxidation yamangqamuzana e-macular, okubangela ukulimala kokubona.

Esweni lomuntu, abantu ngemva kwesikhathi eside sokuziphendukela kwemvelo, iso lomuntu liye lajwayela ukukhanya kwelanga, lapho ukukhanya kusondela ekukhanyeni kwemvelo, yilapho iso lomuntu lizizwa likhululeke ngokwengeziwe.I-Full Spectrum LED isebenzisa i-violet LED excitation, enciphisa ingxenye yokukhanya okuluhlaza okwesibhakabhaka kusuka empandeni yomthombo wokukhanya ukuze kuncishiswe umonakalo emehlweni.

Ngesikhathi esifanayo, ijika le-spectral le-spectrum eligcwele liseduze nejika le-spectral lokukhanya kwelanga, elingathuthukisa ngokuphumelelayo ukunethezeka kwamehlo omsebenzisi.Ngaphezu kwalokho, i-spectrum egcwele inganciphisa futhi izithiyo zesikhashana ze-retinal microcirculation, futhi ibambezele izithiyo zokuhlinzeka ngegazi ezibangelwa ukomisa kwamehlo nokukhathala, ukuze kuzuzwe ukuvikelwa kwangempela kwamehlo.

Lungisa isimiso sakho somsebenzi

Ngokomthetho wewashi lomuntu lezinto eziphilayo, ubuchopho bomuntu ngokuvamile buqala ukukhiqiza i-melatonin ngo-9 noma 10 ebusuku Njengoba i-melatonin eyengeziwe ikhishwa indlala yobuchopho bomuntu, umzimba wethu uyaqaphela kancane kancane ukuthi udinga ukuphumula nokulala.I-Melatonin iyinto esiza ukunciphisa isikhathi sokuvuka ngaphambi kokulala kanye nesikhathi sokulala, okungathuthukisa izinga lokulala.Futhi le nto inobudlelwane obuseduze nokukhanya abantu abavezwa kukho, ikakhulukazi okuzwela ukukhanya okuluhlaza okwesibhakabhaka, ukukhanya okuluhlaza okwesibhakabhaka kuzoba nomthelela ovimbelayo ku-melatonin ekhiqizwa i-pineal gland yobuchopho bomuntu, isikhathi eside ekukhanyeni okuluhlaza okwesibhakabhaka okuphezulu. imvelo ekhanyayo, futhi iveze nokuphazamiseka kokulala.

Futhi ukuvela kwe-spectrum egcwele kunganikeza ukukhanya kwekhwalithi engcono futhi kuthuthukise indawo yokukhanya yokuphila kwabantu.Izingxenye ezimbalwa zokukhanya okuluhlaza okwesibhakabhaka zingenza indawo yokukhanya esebenza ebusuku yabantu ibe nengqondo, futhi indawo yokukhanya enengqondo ingasiza abantu bakhuthaze ukulala, bakhulise ukukhiqiza futhi bathuthukise isimo sengqondo.

Uma isistimu yokukhanyisa egcwele i-spectrum ingahlanganiswa nokulingisa izinga lokushisa lombala welanga unyaka wonke nangezikhathi ezihlukene zemini nobusuku, ukuze kuhlinzekwe njengokukhanya kwemvelo kwangempela.Ukuhlanganiswa okubili kokubili kuzohambisa ngempela ukukhanya kwelanga endlini, ukuze abasebenzi "bangaliboni ilanga" nabo bakwazi ukuzwa ukunethezeka kokukhanya kwelanga kwemvelo ngaphandle kokushiya ikhaya.

Njengamanje, i-spectrum egcwele isesigabeni esikhulayo, ngenxa yokuthi izindleko zayo ziphakeme kakhulu uma kuqhathaniswa ne-LED evamile, ngezingqinamba zamanani, ngakho-ke i-spectrum egcwele yesabelo semakethe ye-LED emakethe yokukhanyisa ibalwa ngengxenye encane kakhulu.Kodwa ngokuthuthukiswa kobuchwepheshe kanye nokuqwashisa kokukhanyisa ngokuduma, ngikholwa ukuthi kuzoba nabasebenzisi abaningi ababona ukubaluleka kwekhwalithi ye-spectrum egcwele futhi bakhethe ukusebenzisa amalambu agcwele-spectrum kanye nemikhiqizo yezibani, izinkampani ezikhanyisayo zizosekelwe ezidingweni ze imakethe ukwenza imikhiqizo emihle kakhulu egcwele i-spectrum.
