Ukuthintela njani ilitha lesibane

"Ilitha" yinto embi yokukhanyisa.Xa ukukhanya komthombo wokukhanya kuphezulu kakhulu okanye ukuhluka kokukhanya phakathi kwemvelaphi kunye nombindi webala lokujonga likhulu, "i-glare" iya kuvela."I-Glare" isiganeko asichaphazeli nje ukujonga, kodwa sinempembelelo kwimpilo ebonakalayo, enokubangela ukuzonda, ukungahambi kakuhle kunye nokulahlekelwa kwamehlo.

Kubantu abaqhelekileyo, ilitha asiyomvakalelo engaqhelekanga.Ilitha likuyo yonke indawo.Izibane ezisezantsi, izibane ezikhanyayo, izibane eziphakamileyo zeemoto ezizayo kunye nokukhanya kwelanga okuvezwa kolunye udonga lomkhusane weglasi yonke ilitha.Lilonke, ukukhanya okungakhululekanga okwenza abantu bazive bemenyezele kukubengezela.

Lenziwa njani ilitha?Esona sizathu siphambili kukusasazeka kokukhanya emehlweni.

Xa ukukhanya kudlula kwiliso lomntu, ngenxa ye-heterogeneity okanye isalathiso esahlukileyo se-refractive samacandelo abandakanya i-stroma ye-refractive, i-propagation direction ye-event light light iyatshintsha, kunye nokukhanya okuphumayo okuxutywe nokukhanya okusasaziweyo kuqikelelwa kwi-retina, okukhokelela ekubeni ukunciphisa ukungafani komfanekiso we-retinal, okukhokelela ekunciphiseni komgangatho obonakalayo weliso lomntu.

Ngokwemiphumo yokumenyezela, inokwahlulwa ibe ziindidi ezintathu: ilitha eliguquguqukayo, ilitha elingemnandanga kunye ne-incapacitated glare.

Ilitha eliguqukayo

Ibhekisela kwinto yokuba xa umntu ehamba kwindawo emnyama (i-cinema okanye itonela engaphantsi komhlaba, njl.njl.) ukuya kwindawo eqaqambileyo, ngenxa yomthombo oqinileyo we-glare, indawo ephakathi emnyama yenziwa kwi-retina yeliso lomntu, okubangela ukuba kungabonakali. umbono kunye nokuncipha kokubona.Ngokuqhelekileyo, inokubuyiselwa emva kwexesha elifutshane lokuziqhelanisa.

Ilitha elingaguqukiyo

Ikwabizwa ngokuba yi "psychological glare", ibhekisa ekungonwabini okubonakalayo okubangelwa kukusasazwa kokukhanya okungafanelekanga kunye nemithombo yokukhanya eqaqambileyo ngaphakathi kwamehlo (njengokufunda kwilanga elinamandla okanye ukubukela umabonakude oqaqambileyo kwindlu emnyama).Oku kungahambi kakuhle, siqhele ukuphepha ukulahleka kombono ngokubaleka okubonakalayo.Nangona kunjalo, ukuba uhlala kwindawo engafanelekanga kwi-glare ixesha elide, kuya kubangela ukukhathala okubonakalayo, intlungu yamehlo, iinyembezi kunye nokulahleka kombono;

Ikhubaza i-Gree

Ibhekisela kwinto yokuba ukungafani komfanekiso we-retina wehla ngenxa yemithombo yokukhanya ye-glare ephazamisayo ngeenxa zonke, ekhokelela kubunzima bokuhlalutya komfanekiso yingqondo, okukhokelela ekunciphiseni umsebenzi obonakalayo okanye ubumfama bexeshana.Amava okuba mnyama ngenxa yokujonga ilanga ixesha elide okanye ukhanyiswa ngumtha ophakamileyo wemoto ephambi kwakho litha elingenakukwazi ukwenza.

Iparamitha yengqondo yokulinganisa iiparamitha ze-glare yesibane yi-UGR (Umlinganiselo odibeneyo we-glare).Ngo-1995, i-CIE yamkela ngokusesikweni ixabiso le-UGR njengesalathiso sokuvavanya ilitha elingathandekiyo lokusingqongileyo kokukhanya.Ngo-2001, i-ISO (International Organisation for Standardization) ifake ixabiso le-UGR kumgangatho wokukhanyisa kwindawo yokusebenza yangaphakathi.

Ixabiso le-UGR yemveliso yokukhanyisa yahlulwe ngolu hlobo lulandelayo:

25-28: ilitha elibukhali elinganyamezelekiyo

I-22-25: iyakhazimla kwaye ayikhululeki

19-22: ilitha eliqaqambileyo nelinyamezelekayo

I-16-19: inqanaba lokubengezela elamkelekileyo.Umzekelo, le fayile isebenza kwindawo efuna ukukhanya ixesha elide kwiiofisi nakwiiklasi.

I-13-16: musa ukuziva udangele

10-13: akukho ilitha

< 10: iimveliso zebakala lobungcali, zisebenza kwigumbi lokusebenza esibhedlele

Ukulungiswa kwezibane, ilitha elingaguqukiyo kunye nokukhubaza ukuqaqamba kunokwenzeka ngexesha elinye okanye lodwa.Ngokufanayo, i-UGR ayisiyophazili ebonakalayo kuphela, kodwa ikwayipuzzle kuyilo kunye nokusetyenziswa.Ngokwenyani, ungayinciphisa njani i-UGR ukuthuthuzela ixabiso kangangoko kunokwenzeka?Kwizibane, ixabiso eliphantsi le-UGR lexabiso alithethi ukususa ukukhanya xa ujonge ngqo kwizibane, kodwa ukunciphisa ukukhanya kwi-engile ethile.

1.Eyokuqala kuyilo

Izibane zenziwe ngeqokobhe, umbane, umthombo wokukhanya, ilensi okanye iglasi.Kwinqanaba lokuqala loyilo, kukho iindlela ezininzi zokulawula ixabiso le-UGR, njengokulawula ukuqaqamba komthombo wokukhanya, okanye ukwenza uyilo oluchasene nokukhazimla kwilensi nakwiglasi, njengoko kubonisiwe kulo mfanekiso ulandelayo:

2. Iseyingxaki yoyilo

Kwishishini, kuvunyelwene ngokubanzi ukuba akukho UGR xa izibane zihlangabezana nale miqathango ilandelayo:

① VCP (ithuba lokuthuthuzela okubonwayo) ≥ 70;

② Xa ijongwa ngobude okanye ngokunqamlezileyo kwigumbi, umlinganiselo wokukhanya kwesibane ukuya kumndilili wokukhanya kwesibane kwii-engile ezingama-45 °, 55 °, 65 °, 75 ° kunye nama-85 ° ukusuka nkqo ≤ 5:1;

③ Ukunqanda ilitha elingathandekiyo, obona kukhanya buphezulu kwi-engile nganye yesibane kunye nomgca othe nkqo awuzukugqithisa amalungiselelo etheyibhile ilandelayo xa ijongwe ngobude okanye ngokunqamlezileyo:

3. Iindlela zokulawula i-UGR kwixesha elizayo

1) Gwema ukufaka izibane kwindawo yokuphazamiseka;

2) Izinto zokuhlobisa umphezulu we-gloss ephantsi ziya kwamkelwa, kwaye i-coefficient yokubonisa iya kulawulwa phakathi kwe-0.3 ~ 0.5, engayi kuba phezulu kakhulu;

3) Nciphisa ukukhanya kwezibane.

Ebomini, sinokuhlengahlengisa ezinye iimeko zokusingqongileyo ukuze sizame ukugcina ukuqaqamba kwezibane ezahlukahlukeneyo kwintsimi yombono ngokungaguquguqukiyo, ukuze kuncitshiswe impembelelo yalo litha kuthi.

Ayiyonyani into yokuba okukhona ukukhanya kuqaqamba, kokukhona kungcono.Ukukhanya okuphezulu okunokuthi kuthwale amehlo abantu malunga ne-106cd / ㎡.Ngaphaya kweli xabiso, iretina inokonakala.Ngokomgaqo, ukukhanya okufanelekileyo emehlweni abantu kufuneka kulawulwe ngaphakathi kwe-300lux, kwaye umlinganiselo wokukhanya kufuneka ulawulwe malunga ne-1: 5.

I-glare yenye yezona zinto zibalulekileyo ezichaphazela umgangatho wokukhanyisa.Ukuze kuphuculwe umgangatho wendawo yokukhanya kwekhaya, iofisi kunye nezorhwebo, amanyathelo afanelekileyo kufuneka athathwe ukunciphisa okanye ukuthintela ukukhanya.I-Wellway inokunqanda ngokufanelekileyo ilitha kwaye ibonelele abathengi ngendawo epholileyo kunye nenempilo yokukhanya ngoyilo lokukhanyisa kwangaphambili, ukhetho lwesibane kunye nezinye iindlela.

UkuthathakakuhleI-LED louver fitting, i-ELS series njengomzekelo, sithatha i-lens ephezulu kunye ne-aluminium reflector, i-grille egqwesileyo yoyilo kunye nokukhanya okukhanyayo okukhanyayo ukwenza i-UGR yemveliso ifikelele kwi-16, enokuthi ihlangabezane neemfuno zokukhanyisa kumagumbi okufundela, izibhedlele. , ii-ofisi kunye nezinye iindawo ezingqongileyo, kunye nokudala ukukhanya okukhanyayo nokunempilo okusingqongileyo kwiqela elikhethekileyo labantu.
