Chiremba wese akamira pasi pechiedza chinoita kuti nyama iite seisina kunaka. Kwete kungoti rima - ruvara rwakashata. Utumbo hunofanira kunge hwakaita seruvara rwepingi hunotaridzika kunge grey, uye ropa remutsinga rinova rakaoma kuona kubva mutsinga. Chikonzero hachiwanzo kuve kusimba. Kazhinji kacho inhamba mbiri dziri padatasheet: indekisi yekuratidza ruvara (CRI) uye tembiricha yeruvara. Kunzwisisa maparamita maviri aya ndiko musiyano uripo pakati pekutenga chiedza chinobata mufananidzo webhurocha nekutenga chinoratidza nyama sezvazviri chaizvo.
Zvinonyatsoonekwa neCRI
CRI, inowanzo nyorwa seRa, chikero che 0–100 chinoenzanisa kuti chiedza chinoburitsa sei mavara nemazvo zvichienderana nereferensi — chiedza chezuva kana radiator yemuviri mutema — iyo inowana 100. Hazvina chekuita nekupenya. Chiedza chinogona kuva chakasimba asi chichiita kuti mavara asashande zvakanaka.
Rudzi urwu runoratidza avhareji yekuvimbika kwemavara masere emhando yepamusoro ekuyedza. Mhando dzakareba dzinowedzera samples dzakaguta, uye chinonyanya kukosha mukuvhiyiwa iR9, tsvuku yakadzama. Ropa, tsandanyama nemukati zvakazara netsvuku dzakanyanya kunaka kupfuura magadzirirwo ekutanga eLED. Chinhu chinogona kuwana Ra 95 asi chisina simba paR9, saka nhamba yemusoro wenyaya yakakodzera kuverengwa neziso rimwe chete papepa diki.
Nei CRI Yakanyanya Kukosha Mukamuri Rekuvhiya
Sarudzo dzekuvhiya dzinoitwa pakusarudza kusiyana kwemavara kudiki. Kusiyanisa kubuda ropa mutsinga dzeropa kubva mutsinga, kuona mucheto wenyama yakafa uye kuongorora kuyerera kweropa zvese zvinoenderana nekuona matsvuku chaiwo. Kusagadzirwa zvakanaka kunobvisa musiyano iwoyo. Chinoita se "chakasviba zvishoma" pasi pechiedza cheCRI chidiki chinowanzova ruvara rwakasiyana rwetsvuku zvachose.
Vanachiremba vazhinji vanovhiya vanoyeuka nyaya chaiyo. Ura hwacho hwairatidzika kunge hwakasviba, chikwata hachina kukwanisa kubvumirana kuti yaive ischemia here kana kuti rambi chete, uye kugadzirisa musoro hakuna chakwakaita - nekuti dambudziko raive risiri kona asi spectrum. Kuchinja kwakabva chiedza uye nyama imwe chete inoverenga zvakasiyana. Ndiyo nzira chaiyo yekuedza chiedza chekuvhiya.
Mitemo inotora izvi zvakakomba. IEC 60601-2-41, chiyero chekuchengetedza uye mashandiro emagetsi ekuvhiya, inoisa CRI shoma yeRa 85, uye gwara rekiriniki rinowanzo kurudzira Ra 90 kana kupfuura kuti pave nekusiyanisa kwenyama kwakavimbika.Mwenje yekuvhiya ye LEDnguva dzose kuendesa Ra 95 kana kupfuura. Kana mutengesi akataura CRI yakakwira, bvunzawo kukosha kweR9 - ndipo panogara matsvuku.
Kupisa Kwemavara uye Maverengero Eziso Matishu
Kupisa kwemavara, tembiricha yemavara yakabatana (CCT), inotsanangura kuti chiedza chichena chinoonekwa sei. Chinoda kusvika 3,000–3,800K chinotaridzika sechinodziya uye cheyero; pedyo ne5,000 K chinosvika pachiedza chezuva; pamusoro pe5,400 K chinoshanduka kuita bhuruu. Mwenje yekuvhiya iri mukati mebhendi re3,000–6,700K rinobvumirwa nemutemo, uye midziyo yakawanda yemukamuri rekuvhiyira inoshanda pa4,000–5,000 K.
Sarudzo yacho haisi yekunaka. Chiedza chinodziya chiri pedyo ne3,800K chinonyorova panyama tsvuku uye chinozorodza panguva refu, asi chinogona kufukidza cyanosis. Chiedza chakaita sechiedza chemasikati pa4,500–5,000K chinorodza musiyano uripo pakati pemagadzirirwo akanaka nenyama - chinobatsira kana uchishanda mukati megomba umo musiyano ndiwo wega wauinawo. Zvimwe zvinhu zvemazuva ano zvinopa tembiricha inogadziriswa yemavara, zvichiita kuti timu ichinje maitiro pasina kuchinja musoro wechiedza.
CRI neKupisa Kwemavara Hazvina Kufanana
Uku ndiko kuvhiringidzika kunowanzoitika muOR corridor. CRI inokuudza kuti mavara anogadzirwa sei; tembiricha yemavara inokuudza kuti chiedza chinodziya kana kuti chinotonhorera sei. Iwo ma axes akazvimiririra. Balbu re halogen rinoita ruvara zvakanaka kwazvo - itsime remuviri mutema nekugadzirwa - asi rinogara pa3,200K yakaderera, yeyero. Ma LED ekutanga aibata tembiricha yemavara zvakanaka asi pakutanga ainetseka nekuita, kunyanya matsvuku akadzika. Mwenje miviri inogona kugovana tembiricha yemavara uye ichiri kusiyana zvakanyanya mukuvimbika kwemavara, saka nhamba imwe chete inokuudza zvishoma.
Zvekutarisa Usati Wasarudza
Verenga pepa redata semuongorori wezvirwere, kwete mutengi. Tarisa CRI Ra kutanga - ndiyo nzira yekuyera mavara - wobva watarisa R9, wobva watarisa tembiricha yemavara, wobva watarisa chiedza semubvunzo wakasiyana. Edza chiedza chiri panzvimbo kana uchikwanisa - isa ruoko rwakaputirwa magiravhu pasi pacho woverenga mavara eganda. Simbisa kuti chigadzirwa chacho chakatenderwa neIEC 60601-2-41 chisati chasvika kuOR yako.
Nheyo dzakafanana dzinoshanda kana uri kure kure.Mwenje yekuvhiya ye LEDuye ma loupe anoshanda mukati menzvimbo yakatarwa yekushanda, uko chiedza chinofanira kuva chakarurama serambi repadenga - uye kazhinji, nekuti nzvimbo yacho idiki uye kuchinja kwemavara kwese kunowedzerwa. Kune mwenje wepamberi, CRI nekupisa kwemavara zvakakosha semufananidzo wemwenje.
KuMicare, tinotsanangura marambi edu ekuvhiya e LED nema loupes akatenderedza nhamba idzi mbiri pane kungotenderedza kupenya chete, uye tinogovana data rakazara re photometric — CRI, R9 uye tembiricha yemavara — usati waedza imwe unit. Kana chiedza chikaratidza tishu zvechokwadi, timu yese inoshanda zviri nani. Iro ipepa reruzivo risingafaniri kudziviswa nachiremba.
