Ndinotenda kuti munhu wese ari muindasitiri yekuvhenekesa akadzidza nezveruzivo rwekutanga rwekupisa kwemavara: tembiricha yakaderera yeruvara inoita kuti vanhu vanzwe vakasununguka uye vachidziya, tembiricha yemhando yepamusoro yakadzikama uye inonakidza, mukuita dhizaini ichateverawo pfungwa iyi.

Nekudaro, hutano chaihwo hwenzvimbo yechiedza, kwete chete haina kupenya, hapana strobe, kungotarisa kupenya, tembiricha yemavara, kufanana hakuna kukwana, isu tinodawo kutarisisa kune "yakaenzana rima pixel illuminance" kukosha kuri mumutsara. nechiyero.

Munzira yekuyera kukosha uku tisati tatanga kuziva pfungwa ye "melatonin".

Melatonin

Kwemabhiriyoni emakore, chiedza chezuva chakashanda sechinhu chekutanga uye chega chechiedza chakaumba endogenous circadian rhythms yezvipenyu zvese.

Chikonzero nei vanhu vachizotevedzera "kubuda kwezuva kushanda, kuvira kwezuva kuti vazorore", mitemo yehupenyu, nekuti pineal gland yehuropi hwemunhu inoburitsa hormone: melatonin, inova "mapiritsi ekurara echisikigo", ndeyemuviri wedu. pakarepo "chiratidzo chekuzorora".“Piritsi rekukotsirisa chairo”, rinova “chiratidzo chekuzorora” chemuviri wedu.Kana muviri uine melatonin yakawanda, tinozobatwa nehope;kana iyo melatonin yemukati iri shoma, isu tichava nesimba.

Uye huwandu hwe melatonin hunovanzwa hune hukama nekusimba kwechiedza.Nekuti kune yakazvimirira photosensitive retinal ganglion masero (ipRGCs) muretina yedu, iyo inogona kugadzira iyo photoreceptor protein, melanopsin, iyo inonzwa kusimba kwechiedza uye kutumira masaini kune pineal gland, zvichikanganisa kugadzirwa kwe melatonin: zvakanyanya murima, zvishoma mu chiedza chakajeka.kune pineal gland, iyo inobata melatonin secretion: yakawanda murima uye zvishoma muchiedza chakajeka.Ichi ndicho chikonzero zviri nyore kurara murima.

Kutora yekutanga "mwenje wekugadzira" - mwenje wemoto semuenzaniso, tembiricha yeruvara rwayo yaive ye2000K, ine shoma shoma yebhuruu uye yakawanda tsvuku mwenje.Iyi yakaderera ruvara tembiricha inodziya mwenje, inoita kuti vanhu vanzwe kugadzikana, inogona kukurumidza kupinda munzvimbo yekurara.

Zvichienderana neizvi, tinogona kuongorora akawanda mapoinzi:

a.Vanhu vanoda marudzi akasiyana echiedza pazvido zvakasiyana;

b.Chiedza chichena chinoita kuti vanhu vamuke uye vafare, uye chiedza cheyero chinoita kuti vanhu vasununguke uye vagadzikane;

c.Izvo zvakakosha kuseri ndiko kuburitswa kwe "natural sleeping pill" melatonin;

d.Chiedza chebhuruu chinomutsa "melatonin photoreceptor masero" uye chinodzivisa kubudiswa kwe melatonin.

Aya ndiwo zvakare hwaro hwehupenyu hweHuman Centric Lighting. 

Tsanangudzo uye maitiro e melatonin illuminance

Manera ekushanduka kwehupenyu anoyerwa mumazana ezviuru zvemakore, nepo nhoroondo yebudiriro yemunhu isingasviki makore gumi.Vanhu vakashandura kumararamiro emazuva ano maererano ne "software" yepfungwa uye yetsika, asi "hardware" yehutano hwepanyama haina kuramba ichienderana nekuchinja.Iyo "biological wachi" mumuviri wedu inzvimbo yakadaro "hardware" isingakwanise kuenderana nekuchinja.Kuvhiringidzwa kwewachi yebhayoloji kunokanganisa zvakananga kurara, asi zvakare kunotungamirira kuhurombo, zvichikonzera kufutisa, chirwere cheshuga uye zvimwe zvirwere zvemetabolism.

Asi ikozvino kuda kudzikisira kuvhenekera kwehusiku hazvigoneke, saka isu tinofanirwa kufunga: rudzii rwemwenje sisitimu isingakonzerese biological clock disorder?

Taida kugadzira sisitimu yekuvhenekesa iyo yaizopa kurudziro yakakwana mukati mezuva kuti tirambe takamuka, uye mwenje wehusiku waizogutsa zvido zvekuona pasina kudzvanyirira melatonin secretion yakawandisa kuvhiringa kunaka kwekurara.

Kuti uite izvi, parameter yekuyera kuyerwa kwaidiwa, saka masayendisiti akatsanangura kukosha uku kutsva kwekuvhenekera: EML (Equivalent Melanopic Lux), Equivalent Melanopic Illuminance, inozivikanwawo seRetinotopic Equivalent Lux.zvinoreva chiyero chephotometric chinoshandiswa kuyera mwero wekukurudzira kwephotopic mhinduro yechiedza chechiedza kune nhema opsins.(Tsanangudzo yakatorwa kubva kuWELL Building Standards)

Conventional illuminance lux (lx) inoshandiswa kuyera kunzwisiswa kwechiedza chemasero ekoni, kutsanangura zvakanyanya mwenje unobvumira ziso remunhu kuona zvinhu.

Equivalent melanopic illuminance (EML), kune rumwe rutivi, inoshandura iyo spectral stimulus yechiedza sosi nekuirema nemhinduro yeIPRGCs kuti ijekese senzira yekutsanangura muhuwandu mhedzisiro yehupenyu hwechiedza pamunhu senzira yekupa rutsigiro. kuitira hutano hwe circadian rhythms.

Chiedza chine EML yakakwira chinowedzera kusvinura, uye chiedza chine yakaderera EML chinosimudzira kubuda kwemelatonin yemuviri uye kuderedza kusvinura.Naizvozvo, zvisinei kuti unoshanda pakubuda kwezuva kana kubuda masikati, unofanira kusarudza chiedza chine EML yakakwirira paunenge uchishanda uye uchishingaira, uye chinja kuchiedza chine EML yakaderera paunozorora uye usati waenda kunorara.

Iyo yakamboburitswa uye ine chiremera sosi yehuwandu hwemirau paEML ndiyo WELL Building Standard.

Kuyerwa kweyakaenzana melatonin illuminance level

Iye zvino zvatava kuziva basa reEML nemitemo yakakodzera, tingaziva sei kukosha kweEML chaiko?

Pane nzira nhatu dzekuita izvi: ① kuyerwa uchishandisa chiridzwa chephotometric; ②kushandurwa kuri nyore kwereshiyo; uye③kunyatso kutendeuka.

Kungave kuyerwa kwemazuva ese, kugamuchirwa kweprojekiti, kana vatengi vanogutsa, vagadziri vanofanirwa kushandisa hunyanzvi mafotometric zviridzwa kuyedza uye kutaura nedata.

Pamusoro pezviratidziro zvina zvakakosha zvechiedza, tembiricha yeruvara, kusiyanisa kwekuona, uye kufanana, chiridzwa chefotometric chakawedzerawo chiyero che melatonin chekuvhenekera, icho chinoenderana nepasi rose WELL Healthy Building Standard ™ mwenje nharaunda paramita, ine kuyerwa kukanganisa kwe <5%.

The simple ratio conversion method inoreva kuyera kana kuverenga zvakajairwa "standard visual illuminance" values ​​using illuminance meters, DIALux simulation software, etc. Illuminance values ​​dzinobva dzashandurwa kuita EML.lx uye EML conversion ratios inosiyana kune akasiyana magetsi masosi.

Semuenzaniso, kana mwenje we incandescent ukavhenekera nzvimbo pa 200 lx, mwenje we melatonin panguva iyoyo i200 x 0.54 = 108 EML.

Ehezve, kunyangwe iine mamwe mwenje masosi uye yakafanana tembiricha yemavara, iyo EML kukosha inofanira kunge yakasiyana kana spectral kugoverwa kwakasiyana.

Kana imwe mwenje sosi isingawanikwe muTafura L1, ndinoishandura sei?Apa ndipo panouya yechipiri nzira yekutendeuka: chaiyo spectral shanduko.

Kusimba kwehumwe pawavelength yega yega kunotanga kuyerwa uye nekuyerwa neformula yakatsanangurwa kuverenga iyo chaiyo EML reshiyo.

Semuyenzaniso, kana ndichida kushandisa BLV 4000K kapu yekuvheneka muimba yangu yekurara, ndofanira kuidzima sei husiku?

Zvinoenderana neiyo WELL yekuvaka chiyero chemakamuri ekurara: iyo EML inofanirwa kunge iri pasi pemakumi mashanu husiku, ipapo kuvhenekera mukamuri kunofanirwa kudzorwa pazasi 50 ÷ 0.87 = 58 lx muDIALux simulation.

Izvo zviri pamusoro ndiyo "yakaenzana melatonin illuminance" yezvakasikwa, sosi, kuyerwa kwezviri mukati, ndinotenda kuti une imwe nzwisiso yezvinhu zvevanhu mwenje, uyezve inogona kushandiswa mukugadzira pfungwa iyi.
