Isingeniso
I-LED njengoba sazi ukuthi isineminyaka engaphezu kwengu-50 ikhona.Ukuthuthukiswa kwakamuva kwama-LED amhlophe yikho okulethe emehlweni omphakathi njengokuthatha indawo yeminye imithombo yokukhanya okumhlophe.Uma kuqhathaniswa nemithombo yokukhanya yendabuko,I-LED ayivezi nje kuphela izinzuzo zokonga amandla nokuphila isikhathi eside, kodwa futhi ivula umnyango idizayini entsha evumelana nezimo yokufaka amadijithali nokushuna umbala.Kunezindlela ezimbili eziyinhloko zokukhiqiza ama-diode amhlophe akhipha ukukhanya (ama-WLED) akhiqiza ukukhanya okumhlophe okunamandla.Eyodwa iwukusebenzisa ama-LED angawodwana akhipha imibala emithathu eyinhloko—obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka. —bese uhlanganisa imibala emithathu ukuze wenze ukukhanya okumhlophe.Okunye ukusebenzisa izinto ze-phosphor ukuze uguqule ukukhanya kwe-LED okuluhlaza okwesibhakabhaka oku monochromatic noma oku-violet kube ukukhanya okumhlophe okubanzi,, ngendlela efanayo nesibani se-fluorescent esisebenza ngayo.Kubalulekile ukuqaphela ukuthi 'ubumhlophe' bokukhanya okukhiqizwayo empeleni kwakhiwe ukuze kuhambisane neso lomuntu, futhi kuye ngesimo kungase kungafaneleki ngaso sonke isikhathi ukucabanga ngakho njengokukhanya okumhlophe.
Ukukhanyisa okuhlakaniphile kuyindawo ebalulekile esakhiweni esihlakaniphile kanye nedolobha elihlakaniphile namuhla.Inani elandayo labakhiqizi libamba iqhaza ekwakhiweni nasekufakweni kwezibani ezihlakaniphile ekwakhiweni okusha.Umphumela uwukuthi inani elikhulu lamaphethini okuxhumana liyasetshenziswa emikhiqizweni ehlukahlukene. ,ezifana ne-KNx ) BACnetP',DALI，ZigBee-ZHAZBA'，PLC-Lonworks, njll.Inkinga eyodwa ebalulekile kuyo yonke le mikhiqizo ukuthi ayikwazi ukusebenzisana (okungukuthi, ukusebenzisana okuphansi nokunwebeka).
Izibani ze-LED ezinekhono lokuletha imibala ehlukahlukene yokukhanya bezilokhu zisemakethe yokukhanyisa yezakhiwo kusukela ezinsukwini zakuqala zokukhanya okuqinile kombuso (SSL). Yize, ukukhanyisa okuguqulekayo ngemibala kusawumsebenzi oqhubekayo futhi kudinga inani elithile lomsebenzi wesikole owenziwa yi isicacisi uma ukufaka kuzophumelela.Kunezigaba ezintathu eziyisisekelo zezinhlobo zokushuna imibala ezikhanyisini ze-LED: ukushuna okumhlophe, ukufiphala kuya kukufudumala, nokushuna kombala ogcwele.Zontathu lezi zigaba zingalawulwa isidlulisi esingenantambo kusetshenziswa i-Zigbee, i-Wi-Fi, i-Bluetooth noma ezinye izimiso, futhi zifakwe ngokuqinile ekwakheni amandla.Ngenxa yalezi zinketho, i-LED inikeza izixazululo ezingaba khona zokushintsha umbala noma i-CCT ukuze ihlangabezane nesigqi sokujikeleza komuntu.
I-Circadian Rhythms
Izitshalo nezilwane zibonisa amaphethini ezinguquko zokuziphatha nezokuphila cishe ngomjikelezo wamahora angu-24 ophinda ezinsukwini ezilandelanayo-lezi izigqi ze-circadian.Izigqi ze-Circadian zithonywa isigqi sangaphandle kanye ne-endogenous.
I-circadian rhythm ilawulwa yi-Melatonin okungenye yamahomoni amakhulu akhiqizwa ebuchosheni.Futhi kubangela ubuthongo.Izamukeli ze-Melanopsin zisetha isigaba sokujikeleza ngokukhanya okuluhlaza okwesibhakabhaka ekuvukeni ngokuvala ukukhiqizwa kwe-melatonin".Ukuchayeka kumaza okukhanya afanayo aluhlaza kusihlwa kuzophazamisa ukulala futhi kuphazamise isigqi se-circadian. Ukukhishwa kwe-Circadian kuvimbela umzimba ekukhanyeni ukungena ngokugcwele ezigabeni ezihlukahlukene zokulala, okuyisikhathi esibalulekile sokubuyisela emzimbeni womuntu. Ngaphezu kwalokho, umthelela wokuphazamiseka kokujikeleza udlulela ngalé kokucabangela phakathi nosuku nokulala ebusuku.
Mayelana nesigqi sebhayoloji kubantu singakalwa ngezindlela ezimbalwa ngokuvamile, umjikelezo wokulala/ukuvuka, izinga lokushisa lomzimba eliwumgogodla, i-melatoninconcentration, ukugxilisa ingqondo kwe-cortisol, nokugxilisa ingqondo kwe-Alpha amylase8.Kodwa ukukhanya ama-synchronizers ayinhloko wesigqi se-circadian endaweni yendawo emhlabeni, ngenxa yokuthi ukukhanya, ukusatshalaliswa kwe-spectrum, isikhathi nobude besikhathi kungaba nomthelela ohlelweni lomuntu lwe-circadian.Lokho kuthinta newashi langaphakathi lansuku zonke.Isikhathi sokuchayeka kokukhanya singaqhubekela phambili noma sibambezele iwashi langaphakathi".Isigqi se-circadian sizoba nomthelela ekusebenzeni komuntu nokunethezeka njll.Isistimu ye-human circadian izwela kakhulu ekukhanyeni kokuthi 460nm (isifunda esiluhlaza okwesibhakabhaka se-spectrum ebonakalayo), kuyilapho isistimu yokubuka izwela kakhulu. kuya ku-555nm (isifunda esiluhlaza).Ngakho-ke indlela yokusebenzisa i-CCT efundekayo kanye namandla ukuze kuthuthukiswe izinga lempilo kuya ngokuya kubaluleke kakhulu.Ama-LED aguqulekayo ngombala anesistimu ehlanganisiwe yokuzwa nokulawula angathuthukiswa ukuze ahlangabezane nokusebenza okuphezulu okungaka,izidingo zokukhanyisa ezinempilo. .
