High CRI LED Lighting Products
Pali zinthu zambiri zomwe muyenera kuziganizira pogula zowunikira za LED kuposa mababu a incandescent, makamaka pamene mababu a incandescent ndiye ukadaulo wokhawo pamsika. Chimodzi mwazinthu izi ndi kuyeza kwa zinthu zowunikira zapamwamba za CRI LED.
I. Kodi CRI mu kuyatsa kwa LED ndi chiyani?
Mfundo zambiri zimagogomezera kwambiri colour rendering index (CRI), yomwe imayesa mphamvu ya kuwala kutulutsa mitundu molondola komanso kufanana ndi mitundu yachilengedwe ya kuwala kwadzuwa. Pamene CRI ya nyali ya LED ndi yayikulu kuposa 90, imatengedwa ngati CRI LED yapamwamba.
CRI imawerengedwa ngati mtengo wokhala ndi chiwerengero chokwanira cha 100. Chiwerengero cha CRI choposa 90 chimatanthauza kuti gwero la kuwala limapangitsa chinthucho kukhala chofanana kwambiri ndi maonekedwe pansi pa kuwala kwachilengedwe. Zowunikira zapamwamba za CRI LED zimakonda kuwonetsa mitundu yodzaza kwambiri kuposa zinthu zomwe zili pansi pa 90 CRI, ndipo zimakondedwa ndi akatswiri ambiri amakamera pazochitika zapa TV ndi wailesi, omwe amakhulupirira kuti kuunikira kwapamwamba kwa CRI LED ndikowunikira kwambiri komanso kotsogola kwamasewera a LED masiku ano.
Kuti muwone kusiyana pakati pa magawo osiyanasiyana a CRI, mutha kulozera ku chithunzi chomwe chili pansipa.
II. Kodi pali ubale wotani pakati pa CRI ndi Lumen pakuwunikira kwa LED?
Monga mukuwonera, ma toni a CRI ndi owoneka bwino komanso achilengedwe pachithunzi pamwambapa. Komabe, kuoneka bwino ndi chiyero zimabwera pamtengo. Kukwera kwa CRI, kuwala kwa lumen kumatsika pang'onopang'ono kuchokera ku kuwala kwa LED. Kuti ndikupatseni zambiri, nazi kuchepetsedwa kwa lumen komwe mungafune kuwona kutsika kwa lumen poyerekeza ndi CRI 70 wamba:
CRI 80 -> -10%
CRI 85 -> -15%
CRI 90 -> -20%
CRI 95 -> -25%
Chifukwa chake, ngati projekiti yanu yamasewera kapena mafakitale ikufuna CRI95, mudzagula 20% ya mphamvu zowonjezera kuti mukhalebe ndi milingo ya lumen yokhazikika ndikusunga kuwala kowerengera.
III. Zimawononga ndalama zingati kukhala ndi nyali yayikulu ya CRI?
Kwa masewera apamwamba kwambiri kapena mabwalo amasewera pa mlungu uliwonse HD TV kapena kuwulutsa kwa 4K, ma CRI LED apamwamba angafunike kuyambira 90 mpaka 95. mulingo wapamwamba kwambiri pamtunda pafupifupi 800 lux.
Kotero ngati mukufunikira kugwiritsa ntchito zowunikira zapamwamba za CRI LED pulojekiti yanu, mtengo wapamwamba wa CRI LED wowunikira umagwirizana ndi mphamvu ya nyali za LED ndi chiwerengero cha nyali za LED zomwe munagwiritsa ntchito polojekitiyi. Takulandirani kuti mukambirane ndi OAK LED Ngati mukufuna ndondomeko yamtengo wapatali yazitsulo zapamwamba za CRI LED.
