Kupenya, kutsungirira, uremu, kuramba kudonha uye kutakura zvinhu zviri pachena uye zvinonyatsozivikanwa zvemwenje wekunze.Naizvozvo, iwowo ndiwo ekutanga kufunga kune vakawanda vashandisi kana uchitenga.Dzinongodiwa.Nhasi, ngatitaure nezve zvimwe zvakakosha asi zvisinganyanyi kuzivikanwa zvemwenje wekunze, seCRI, mwenje weruvara uye tembiricha yeruvara.
Nezve CRI
CRI ndiko kudimburirwa kwechiRungu colour rendering index, zvinoreva kuti color rendering index muchiChinese.Chiyero chekupa cheruvara chairwo rwechinhu nechinobva pachiedza chinova chiratidziro cheruvara rwechiedza.CRI ndiyo quantification yekupa ruvara.Indekisi yeruvara inoburitsa yechiedza chemazuva ese (sechiedza chezuva) chinotsanangurwa se 100, uye indekisi yeruvara yezvimwe zvivheneko yakaderera pane 100 Kukwirisa kweruvara kunopa, ndiko kuswedera kweindekisi yeruvara kunosvika zana, ndiko kusimba. kukwanisa kudzorera ruvara rwechinhu chacho, uye zviri nyore kuti ziso remunhu riparadzanise ruvara rwechinhu, saka manzwiro ekuona ari nani.

Kunze, kupenya kwakanyanya kwetochi kunogona kutonga mamiriro echinhu, asi iwo mameseji nematanho anofanirwa kutsigirwa nemavara akanaka ekupa.Kureva kuti, kana iwe uchida kuona chinyorwa chechinhu, iwe unongoda kutarisa chiratidzo chekupenya.Ingave chiri chechiedza chinopisa chine 100 color rendering kana mwenje wemonochromatic usina mavara anoburitsa, kupenya kwakafanana.Kana tichida kutonga ruvara, hudzamu uye mwero wechinhu chacho, 75 ruvara runopa chiedza sosi inoda kupenya kwepamusoro kuti uwane ruzivo rwemavara zana anoburitsa mwenje sosi.
Saka ndedzipi mabhenefiti emhando yepamusoro inopa magetsi masosi?Zviripachena, kutanga kwezvose, regai vanhu vaone zvinhu zvakajeka, izvo zvinonyanya kubatsira kunze.Nekuti haugone kuona zvakajeka, dzimwe nguva harisi dambudziko rekutadza kuona kwekuona chete, asiwo rinogona kukonzera njodzi.Semuyenzaniso, nekuti hauone zvakajeka, unongoerekana wasangana nezvipembenene zvine chepfu, kana kuti hauone nyoka, hauone gomba riri pamberi pako, uye unomhanyira mumugwagwa kwechinguva, zvichingodaro. .Mamwe mabhureki, akadai saKnight Cole, pamwe anofunga izvi, saka ivo vanopa sarudzo yeCRI vhezheni ine yakakwira mavara ekupa mumitsetse yakawanda yechigadzirwa.
Pamusoro pekushisa kwemavara
Nheyo yewhite LED ndeyekuti erekitironi inoburitsa mwenje weblue kuburikidza nechip, uye yobva yafadza phosphor kuburitsa yero mwenje, iyo yakasanganiswa muchena mwenje.Ruvara rwekupihwa kweyero mwenje unonakidzwa nephosphor wakakwira, nepo bhuruu mwenje wemonochromatic.Nokudaro, kuti tivandudze kupa kwemavara, tinofanira kuwedzera chikamu chechiedza cheyero.
Kubva pakuona uku, kudziya kweruvara rwechiedza, zviri nani kupa kwemavara, uye zvakanyanya kukodzera kumitambo yekunze.Pamusoro pezvo, tembiricha yeruvara rwemwenje inodziya yakadzikira, kureba kwewavelength, kupinda kwakasimba mukunaya uye mhute mamiriro ekunze, uye irradiation yakareba.Aya maitiro akabatana anoona kudiwa kwekudziya kwemavara mwenje LED yemitambo yekunze.
Zvisinei, kune rumwe rutivi, kushanda kwefluorescence inofadza kwakaderera.Kupenya kwakazara kweinodziya chena LED kunenge kwakadzikira, uye iwo mwenje ruvara ruchaita serishoma uye yero, iyo inodhaya chinhu chine irradiation semwenje-simba-incandescent rambi.Naizvozvo, pazere, zvakanyanya kukodzera kusarudza zvepakati chena zvigadzirwa zve LED mumitambo yekunze, iyo isina kungoita yakanaka kupa kwemavara uye kupinda mukati, asi zvakare inodzivirira kupenya kwakanyanya kuderedzwa uye dhayi.
