Ngokuqhelekileyo, ilitha lisiganeko apho ukukhanya kukhazimla kwaye kukhwankqisa, okubangela ukuba iliso lomntu libone izinto ngokucacileyo, ezingathandekiyo kwiliso lomntu, okanye zingabonakali kwaphela.Ke ngoko, uyilo lokukhanyisa kufuneka lunciphise ilitha.
Inkcazo esemgangathweni yelitha yile:
Isenzeko esibonwayo esibangela ukungonwabi okanye sinciphise ukukwazi ukujonga iinkcukacha okanye izinto ngenxa yokwabiwa kokuqaqamba okungafanelekanga okanye uluhlu lokukhanya kwibala lokujonga, okanye ubukho bokuchasana kokukhanya okugqithisileyo.-”Isigama soMgangatho wokuLayina koLwakhiwo” JGJ/T 119-2008
Ukukhanya kwezemidlalo kusebenzisa isalathisi se-glare (GR) ukuvavanya iqondo le-glare, eyiparameter yengqondo ukulinganisa impendulo ezimeleyo yeendawo zemidlalo yangaphandle kunye nezinye iindawo zangaphandle izixhobo zokukhanyisa ekunciphiseni ukubonakala kunye nokuziva ungakhululekile okubangelwa ngamehlo abantu.Isuka kumgangatho weCIE.
Kwifomula:
I-Lvi-ukukhanya kwekhethini elikhanyayo (cd / m2) eveliswa ngokukhanya okukhutshwe sisibane esibetha ngokuthe ngqo emehlweni;
Lve-ukukhanya komkhusane wokukhanya (cd/m2) okubangelwa sisiganeko sokukhanya ngokuthe ngqo kwiso esibangelwa yimekobume.
Amaxabiso awohlukeneyo e-GR abonisa idigri ezahlukeneyo zokubengezela, njengoko kubonisiwe kwiTheyibhile yoku-1.
Itheyibhile ye-1 ye-Glare Index kunye ne-Glare Degree
| Glare Quality Class GF | Inqanaba lokuKhanya | Ixabiso le-GR |
| 1 | Ayimkelekanga | 90 |
| 2 | - | 80 |
| 3 | Ungenelelo | 70 |
| 4 | - | 60 |
| 5 | Akwamkelekanga | 50 |
| 6 | - | 40 |
| 7 | Kuyaqondakala | 30 |
| 8 | - | 21 |
| 9 | ND | 10 |
I-GR=50 eyaziwayo ngamazwe ilitha eyamkelekileyo ebantwini, ngoko umgangatho wamazwe ngamazwe ufuna ukuba iGR yokukhanyisa kwezemidlalo kwiindawo ezisesikweni zokhuphiswano ingabi ngaphezu kwama-50.
Ukuthetha ngokuthe ngqo, le fomyula ingentla ifanelekile ukukhanyisa indawo yangaphandle, kwaye ilizwe lam liye landisa esi sicelo kwiindawo zangaphakathi, kwaye isetyenziswe ukususela ngo-2007. Nangona kunjalo, ixabiso le-GR lokukhanyisa indawo yangaphakathi kufuneka lingabi ngaphezu kwe-30.
Ngokuqhelekileyo ilitha leleliso lomntu, elinokubonwa kwingcaciso yelitha.Nangona kunjalo, ngophuhliso losasazo lwezemidlalo, ukhuphiswano olukhulu lukwabeka phambili iimfuno zekhamera.Umzekelo, iMidlalo yeOlimpiki ifuna ukuba i-GR yekhamera ingabikho ngaphezu kwe-40. Ngeenkcukacha, nceda ubhekiselele kwi-monograph yombhali "I-Sports Lighting Design Manual" (i-Sports Lighting Design Manual) (epapashwe yiChina Electric Power Press).
