Indlela yokuvimbela ukuxhopha kwesibani

I-"Glare" yinto embi yokukhanyisa. Uma ukukhanya komthombo wokukhanya kuphezulu kakhulu noma umehluko wokukhanya phakathi kwesizinda nenkaba yenkundla yokubuka mkhulu, "i-glare" izovela. "Glare" okwenzekayo akuthinti nje ukubuka, kodwa futhi kunomthelela empilweni ebonakalayo, engase ibangele ukunengeka, ukungakhululeki ngisho nokulahlekelwa kwamehlo.

Kubantu abavamile, ukucwayiza akuwona umuzwa ongavamile. I-glare ikhona yonke indawo. Amalambu aphansi, amalambu, amalambu aphezulu ezimoto ezizayo kanye nokukhanya kwelanga okuvela kolunye udonga lwamakhethini engilazi konke kungukukhanya. Ngamafuphi nje, ukukhanya okungakhululekile okwenza abantu bazizwe becwebezela kuwukubenyezela.

I-glare yakheka kanjani? Isizathu esiyinhloko ukuhlakazeka kokukhanya emehlweni.

Lapho ukukhanya kudlula esweni lomuntu, ngenxa ye-heterogeneity noma inkomba ehlukile ye-refractive yezingxenye ezenza i-refractive stroma, indlela yokusakazeka kokukhanya kwesigameko kuyashintsha, kanye nokukhanya okuphumayo okuxutshwe nokukhanya okuhlakazekile kukhishelwa ku-retina, okuholela ekutheni ukunciphisa umehluko wesithombe se-retina, okuholela ekwehleni kwekhwalithi ebonakalayo yeso lomuntu.

Ngokwemiphumela yokuxhopha, ingahlukaniswa ngezinhlobo ezintathu: ukuxhopha okuguquguqukayo, ukuxhopha okungakhululekile kanye nokuxhopha okungakwazi ukusebenza.

Ukukhanya okuguquguqukayo

Kubhekisela ekutheni lapho umuntu esuka endaweni emnyama (i-cinema noma umhubhe ongaphansi komhlaba, njll.) eya endaweni ekhanyayo, ngenxa yomthombo onamandla ocwebezelayo, kwakheka indawo emnyama ephakathi ne-retina yeso lomuntu, okuholela ekungacaci kahle. ukubona nokuncipha kokubona. Ngokuvamile, ingabuyiselwa ngemva kwesikhathi esifushane sokuzijwayeza.

Ukuxhopha okungaguquki

Okwaziwa nangokuthi "ukubenyezela kwengqondo", kubhekiselwa ekuphathekeni kabi okubukwayo okubangelwa ukusabalalisa ukukhanya okungafanele kanye nemithombo yokukhanya ekhanyayo ngaphakathi kwamehlo (njengokufunda elangeni elinamandla noma ukubuka i-TV egqamile endlini emnyama). Lokhu kungalungile, ngokuvamile sigwema ukulahlekelwa ukubona ngokuphunyuka okubonakalayo. Kodwa-ke, uma usendaweni engafanele ukuxhopha isikhathi eside, kuzodala ukukhathala okubonakalayo, ubuhlungu bamehlo, izinyembezi nokulahlekelwa umbono;

Ikhubaza i-Glare

Kubhekisela kwinto eyenza umehluko wesithombe se-retina wehla ngenxa yemithombo yokukhanya exhophayo ezungezile, okuholela ebunzimeni bokuhlaziya isithombe ngobuchopho, okuholela ekuncipheni kokusebenza kokubuka noma ubumpumputhe besikhashana. Okuhlangenwe nakho kokuba mnyama ngenxa yokubuka ilanga isikhathi eside noma ukukhanyiswa umsebe ophakeme wemoto ephambi kwakho kuwukukhanya okungenakukwazi ukusebenza.

Ipharamitha yezengqondo yokulinganisa amapharamitha okuxhopha kwesibani i-UGR (Isilinganiso sokuxhopha okuhlanganisiwe). Ngo-1995, i-CIE yamukela ngokusemthethweni inani le-UGR njengenkomba yokuhlola ukubenyezela okungakhululekile kwendawo yokukhanya. Ngo-2001, i-ISO (International Organization for Standardization) yafaka inani le-UGR ezingeni lokukhanyisa lasendaweni yokusebenza yasendlini.

Inani le-UGR lomkhiqizo wokukhanyisa lihlukaniswe ngale ndlela elandelayo:

25-28: ukubenyezela okukhulu okungabekezeleleki

I-22-25: iyakhazimula futhi ayikhululekile

19-22: ukukhanya okukhazimula kancane nokubekezelelekayo

16-19: izinga lokuxhopha elamukelekayo. Isibonelo, leli fayela lisebenza endaweni edinga ukukhanya isikhathi eside emahhovisi nasemakilasini.

13-16: ungazizwa ukhazimula

10-13: akukho ukukhanya

< 10: imikhiqizo yezinga lochwepheshe, esebenza egumbini lokuhlinzela esibhedlela

Ngezinto zokukhanyisa, ukuxhopha okungaguquki kanye nokucwayiza okukhubazayo kungenzeka ngesikhathi esisodwa noma sodwa. Ngokufanayo, i-UGR ayiyona nje iphazili ebonakalayo kuphela, kodwa futhi iyindida ekuklanyweni nasekusetshenzisweni kwayo. Empeleni, ungayinciphisa kanjani i-UGR ukuze iduduze inani ngangokunokwenzeka? Ezibanini, umthamo wenani eliphansi le-UGR awusho ukususa ukukhanya lapho ubheka amalambu ngokuqondile, kodwa ukunciphisa ukukhanya nge-engeli ethile.

1.Okokuqala wumklamo

Amalambu akhiwe ngegobolondo, amandla kagesi, umthombo wokukhanya, ilensi noma ingilazi. Esigabeni sokuqala sokuklama, kunezindlela eziningi zokulawula inani le-UGR, njengokulawula ukukhanya komthombo wokukhanya, noma ukwenza idizayini emelene nokucwebezela kumalensi nengilazi, njengoba kuboniswe esithombeni esilandelayo:

2. Kuseyinkinga yokuklama

Embonini, ngokuvamile kuvunyelwana ngokuthi ayikho i-UGR lapho izibani zihlangabezana nalezi zimo ezilandelayo:

① VCP (amathuba okunethezeka okubonakalayo) ≥ 70;

② Uma ibhekwa ngobude noma ngokuphambeneyo ekamelweni, isilinganiso sokukhanya kwesibani esiphezulu kuya ekukhanyeni kwesibani okumaphakathi kuma-engeli angu-45 °, 55 °, 65 °, 75 ° no-85 ° ukusuka mpo ngu-≤ 5:1;

③ Ukuze ugweme ukuxhopha okungajabulisi, ukukhanya okuphezulu ku-engeli ngayinye yesibani nomugqa oqondile akumele kudlule ukunikezwa kwethebula elilandelayo uma kubhekwa ngobude noma ngokuphambene:

3. Izindlela zokulawula i-UGR esikhathini esizayo

1) Gwema ukufaka izibani endaweni yokuphazamiseka;

2) Izinto zokuhlobisa ezingaphezulu ezine-gloss ephansi zizokwamukelwa, futhi i-reflection coefficient izolawulwa phakathi kuka-0.3 ~ 0.5, okungeke kube phezulu kakhulu;

3) Nciphisa ukukhanya kwezibani.

Empilweni, singakwazi ukulungisa ezinye izici zemvelo ukuze sizame ukugcina ukukhanya kwezibani ezihlukahlukene emkhakheni wokubona kungaguquki, ukuze sinciphise umthelela walokhu kuxhopha kithi.

Akulona iqiniso ukuthi ukukhanya kukhanya, kungcono. Ukukhanya okuphezulu okungakuthwala amehlo omuntu cishe ku-106cd / ㎡. Ngale kwaleli nani, i-retina ingase yonakaliswe. Empeleni, ukukhanya okufanele amehlo omuntu kufanele kulawulwe ku-300lux, futhi isilinganiso sokukhanya kufanele silawulwe cishe ku-1:5.

I-glare ingenye yezinto ezibaluleke kakhulu ezithinta ikhwalithi yokukhanyisa. Ukuze kuthuthukiswe ikhwalithi yendawo yokukhanya yekhaya, ihhovisi kanye nezohwebo, izinyathelo ezifanele kufanele zithathwe ukukhawulela noma ukuvimbela ukuxhopha. I-Wellway ingagwema ngokuphumelelayo ukuxhopha futhi inikeze amakhasimende indawo yokukhanya enethezekile nenempilo ngokuklama ukukhanya kwangaphambi kwesikhathi, ukukhetha izibani nezinye izindlela.

UkuthathakahleI-LED louver fitting, uchungechunge lwe-ELS njengesibonelo, sisebenzisa ilensi yekhwalithi ephezulu kanye nesibonisi se-aluminium, idizayini enhle kakhulu yegrille kanye nokukhanya okukhanyayo okwenza i-UGR yomkhiqizo ifinyelele cishe ku-16, engahlangabezana nezidingo zokukhanya kwamakilasi, izibhedlela. , amahhovisi nezinye izindawo, futhi adale ukukhanya kwemvelo okukhanyayo nokunempilo kweqembu elikhethekile labantu.
