Wekhadi Ukukhanya: Theory and Practice

Ukhanyiso - le Ubukhulu balo, luphawulwa lulwahlulo yesehlo ukukhanya obhobhozayo phezu komhlaba ukuya kwindawo yayo. Kube nokuqodwa ukuba moya umphezulu kufuneka aa Incopho esqwini ukukhanya kwemali.

Ngaphandle amaxabiso ucoceko ngqo kwabantu womlinganiselo kakhulu ukukhanya esetyenziswa lulimo yezilwanyana ngokudala efanelekileyo microclimate zoPhuculo, xa lwemfuyo intlanzi akwariyam ne zityalo ukulinywa kwezityalo potted, ukuchaza iimpawu Izixhobo zokufota neevidiyo, kubandakanywa ividiyo camera esweni.

imithombo sokukhanyisa

Yinto eyaziwayo ukuba kukho izibane yendalo neyenziweyo. Oku kudala imithombo ukukhanya efanelekileyo: libhekisela zendalo kokugquma ukukhanya esibhakabhakeni, Kakade ke, ilanga nokukhanya iboniswe kwenyanga. imithombo Lamalungu - izibane ezahlukeneyo (izibane ezingqengezelayo, izibane obhobhozayo, ezibengezelayo), TV kunye neekhompyutha.

Kutheni kufuneka ukulinganisa illuminance

Ukukhanyisa - enye zezempilo ibalulekileyo, nto leyo kuxhomekeke ngqo kwimpilo yabantu. nomlinganiselo ukukhanya - le nkqubo lubandakanyiwe SanPin (imimiselo zangasese kunye nezithethe), ngenyameko senziwe kwi par emsebenzini kunye imilinganiselo amanqanaba ingxolo, ukungcangcazela, uthuli kunye nongcoliseko negesi.

Oogqirha bathi ukuba ukunqongophala coverage ibandakanya ukwehliswa acuity ezibonwayo, ukudinwa, kunciphise yoxinaniso kunye lulonke nemveliso unokude kunokubangela ingozi. Ukuswela izilwanyana neentaka ukhanyiso ebangela ukuphazamiseka ukukhula, uphuhliso embi iseti ubunzima lomzimba, ukulahlekelwa kwimveliso (izilwanyana basezifama) kunye nesakhono ukuze ukuzala.

lulinganiselwa njani kwaye yintoni iiyunithi, le ubuninzi emzimbeni

isixhobo Light sokulinganisa wenziwa, leyo kuthiwa imitha ukukhanya, isixhobo ephathekayo nto leyo uhlobo photometer. Modern isiphelo eliphezulu-cell phones baye izihluzi. Unit ukhanyiso silinganiso kwinkqubo ngamazwe leeyunithi (SI) - Suite, nto leyo ekhokelele kwireshiyo yama square 1 imitha ukuba le mithambo indawo ngaphezulu. Le lumens kulinganiswa mali ukukhanya ukubhobhoza. Iinkqubo yaseMelika kunye British zisebenzisa loo iyunithi yokulinganisa yokulinganisa illuminance njengoko lumens ngeenyawo square nganye, unyawo-candela (degree of ukhanyiso ukusuka ukukhanya umthombo wamandla 1 candela, bebekwe 1 unyawo ukusuka kumphezulu).

Njani na isikali ukukhanya? Oku kwenziwa ngokusebenzisa imitha ukukhanya, imitha kufuneka abe lokugqibela ngokuxwesileyo, uyibeke kwindawo wacela gumbi. Kwezakhiwo kunye nezibonelelo nemfuyo, kukho ezizodwa emiselweyo imigangatho karhulumente nemiqathango yolawulo ndawo. Sebenzisa umyalelo kwifowuni xa efaka amanzi esatsiba kufuneka ingqalelo eziphango factor apho japan iyanda. Emva koko, iifomyula ezahlukeneyo zibalwa ubuncinane, ngokomlinganiselo, ukhanyiso ophezulu, kwakunye umlinganiselo ukukhanya bendalo.
