Light metering: Dzidziso uye Practice

Jekeso - ichi panyama nokukura, dzinoratidzwa nhamba chiedza nekubudisa chiitiko pamusoro pemvura kuti munharaunda yacho. Chichitsveneswa vakanzwisisa kuti pose ndege inofanira kuva perpendicular kuti chiedza akabatana kuyerera.

Kunze Utsanana tsika zvakananga munhu substantially chiedza chipimo kushandiswa mhuka minda kusika zvakafanira. microclimate Improvement, mu ruminant hove akwariyamu uye miti kuti kurima mumaruva zvinomera, kutsanangura hunhu Photographic uye nemavhidhiyo zvokushandisa, kusanganisira vhidhiyo kamera nokuongororwa.

manyuko okuvhenekesa

Zvinozivikanwa kuti pane zvakasikwa uye chakagadzirwa chiedza. Zvinoita yakakodzera chiedza zvinyorwa: rinoreva kwomuzvarirwo ambient chiedza dzedenga, Chokwadi, zuva uye chiedza chemwedzi. Chakagadzirwa mabhuku - dzakasiyana mwenje (incandescent mwenje, zvinoyerera marambi, fluorescent), TV sefa uye makombiyuta.

Nei tichifanira kuyera illuminance

Lighting - chimwe chezvinhu zvinokosha utano zviratidzo, iyo inobva zvakananga utano hwevanhu. chiedza chipimo - muitiro kunobatanidzwa SanPin (mirayiro utsanana uye dzemunharaunda), vachinyatsoongorora akaita pamusoro kumabasa ndima chete kuyerwa kwevari ruzha, vibration, huruva uye gasi pakusvibiswa.

Vanachiremba vanoti kushaya nhau rinobatanidza zvinoderedza kutarisana acuity, kurukutika, akaderedza yevasungwa uye kunopindirana zvibereko Zvingatovaita tsaona. Mhuka neshiri jekeso kushaikwa kunokonzera kukura kwepfungwa, kukura zvakaipa akagadzirwa vakawanda womuviri, kurasikirwa negoho (nokuti mhuka purazi) uye kukwanisa bereka.

Sei uye chii zviyero kunoyerwa, panyama uwandu ichi

Light metering mudziyo rinoitwa, unonzi chiedza meter, inotakurika zano iri mhando photometer. Modern mukuru-magumo mafoni zvinosanganisira filters. Unit jekeso kuyerwa munyika dzakawanda ino vezvikwata (SI) - Suite, inova nhamba 1 mativi mita kuti lumen pamusoro nharaunda. The lumens akayera chiedza nekubudisa mari. The American uye British nehurongwa anoshandisa vakadaro tambo chikwata tambo illuminance sezvo lumens por rutsoka sikweya, rutsoka-candela (dhigirii okuvhenekesa kubva chiedza tsime simba 1 candela, munzvimbo dzokuzororera dzaiva 1 rutsoka pachiso).

Sei chiedza kuyerwa? Izvi zvinoitwa kushandisa chiedza meter, kuti mita anofanira kuva wokupedzisira pane chinjikira chinzvimbo, muriise iri kutsvakwa yacho mukamuri. For nezvivakwa uye zvipfuwo zvivako, pane chinokosha chairayirwa ehurumende mitemo panzvimbo achidzora matanho. Shandisa mirayiridzo mudziyo kana kushandisa kamwene zvinofanira kufungwa attenuation chinoita naro mugumisiro zvikawanda. Zvadaro, Masvomhu siyana vari nokuenzanisa shoma, paavhareji, kunonyanyisa jekeso, uyewo reshiyo rwokuzvarwa chiedza.
