CRI (spalv\u0173 perteikimo indeksas) - tai \u0161viesos \u0161altinio spalv\u0173 perteikimo kokyb\u0117s matas. Jis rodo, kaip gerai \u0161viesos \u0161altinis atkuria objekt\u0173 spalvas, palyginti su etaloniniu \u0161viesos \u0161altiniu, pvz., dienos \u0161viesosspektru<\/a>.<\/p>\n

Spalv\u0173 perteikimo indeksas matuojamas skal\u0117je nuo 0 iki 100. Vert\u0117 100 rei\u0161kia, kad \u0161viesos \u0161altinis puikiai atkuria objekt\u0173 spalvas. 0 reik\u0161m\u0117 rei\u0161kia, kad \u0161viesos \u0161altinis visi\u0161kai neatspindi objekt\u0173 spalv\u0173.<\/p>\n

LED<\/a>LED lemp\u0173 CRI paprastai b\u016bna 80-95, o tai rei\u0161kia, kad jos gerai atkuria objekt\u0173 spalvas. Ta\u010diau pastaruoju metu toki\u0173 gamintoj\u0173 kaip YUJILEDS galima \u012fsigyti \u0161viesos diod\u0173 lemp\u0173, kuri\u0173 spalv\u0173 perteikimo indeksas yra 100. \u0160ios lempos ypa\u010d tinka naudoti ten, kur svarbu kokybi\u0161kai perteikti spalvas, pavyzd\u017eiui, fotostudijose ar muziejuose.<\/p>\n

Poligrafijos pramon\u0117je D50<\/a> standartin\u0117 \u0161viesa<\/a> yra Europoje paplitusi standartin\u0117 \u0161viesa. Ar jums reikia D50 standartin\u0117s \u0161viesos, priklauso nuo reikalavim\u0173. Jei daikt\u0173 ir spaudini\u0173 spalvas reikia atkurti labai tiksliai, D50 standartin\u0117 \u0161viesa yra geriausias pasirinkimas.<\/p>\n

Ta\u010diau jei spalv\u0173 perteikimo kokyb\u0117s reikalavimai n\u0117ra tokie auk\u0161ti, galima tiesiog naudoti \u0161viesos diod\u0105 su auk\u0161tu CRI. \u0160viesos diod\u0173 lempos, turin\u010dios auk\u0161t\u0105 spalv\u0173 perteikimo indeks\u0105, paprastai yra pigesn\u0117s nei D50 lempos ir jas lengviau rasti.<\/p>\n

Bendrov\u0117je \"Proof<\/a> GmbH\" standartizavome lengv\u0105sias kabinas i\u0161 Just<\/a> su D50 standartine \u0161viesa, bet da\u017enai tik su vienu 500 Kelvin\u0173<\/a> \u0161viesos diodu ir auk\u0161\u010diausiu \u012fmanomu 90+ CRI ant v\u0117jalent\u0117s. Nepaisant to, \u010dia da\u017enai pasitaiko dideli\u0173 spalv\u0173 skirtum\u0173 ir metamerizmo<\/a> efekt\u0173, jei \u012frodymai<\/a> per\u017ei\u016brimi tik ant redagavimo stalo. Tod\u0117l i\u0161samiam spalv\u0173 \u012fvertinimui visada naudojame standartines \u0161viesos kabinas.<\/p>\n

Deja, \u0161iuo metu nesi\u016blomi jokie modernizavimo sprendimai, pavyzd\u017eiui, kaip tiesiog pakeisti \"senas\" D50 standartines neonines lemputes LED lempomis. Kadangi nuo 2024 m. neonin\u0117s lempos bus u\u017edraustos, kei\u010diant sen\u0105sias D50 standartin\u0117s \u0161viesos neonines lempas reikia \u012fsigyti ir sumontuoti visi\u0161kai naujus LED \u012frenginius, pavyzd\u017eiui, \"Just\". \u0160iuo metu pakeitimas vis dar gana brangus - keli t\u016bkstan\u010diai eur\u0173.<\/p>","protected":false},"excerpt":{"rendered":"
