Vanhu vanoyera mwenje vachishandisa zvikamu zvakasiyana seCandela, Lux, neLumens. Wakambofunga nezve yekuongorora mwenje uchishandisa chero yeaya mayunitsi?
Unogona kupinda mudambudziko kuita kudaro nekuti mayunitsi ekuyeresa mwenje Candela, Lux, uye Lumens anowanzo chinjana. Saka ndafunga kuti ndikuponesei kubva mukukangaidzika uku nokuuyisa kusiyana kwavo.
Iwo mayunitsi Candela, Lux, uye Lumens anoyera kusimba kwechiedza. Lux zvinoreva huwandu hwechiedza chinosvika pachinhu. Uye Lumens neCandela ndiwo metrics anoshandiswa kutarisa huwandu hwekubuda kwechiedza.
Asi, mazwi matatu aya anowanzo shandiswa zvisizvo pakusarudza kupenya kwechiedza. Ndokusaka iwe uchifanira kuziva zvavanoreva uye kuti ndezvipi zvinhu zvinoparadzanisa mayunitsi kubva kune mumwe nemumwe.
Ngatinyure muhurukuro tizive zvimwe.
Chii chinonzi Candela?
Candela inotaura iyo Luminous Intensity yechiedza sosi. Iri izwi rakabva paizwi rechiLatini rekuti 'Candela' uye rinoenderana nekusimba kwekenduru. Semuenzaniso, imwe Candela inenge yakaenzana nekupenya kwekenduru.
Mukutaura, Candela inoyera kusimba kwechiedza mune imwe nzira kana kona. Hazvina kujeka? Funga nezveraser light; rinotungamirira chiedza munzira chaiyo. Ndosaka chiyero cheCandela chiri chepamusoro-soro mune laser kana mavara.
Chii chinonzi Lux?
Lux (lx) ndiyo yekuyera chikamu chekuvhenekera. Inoratidza huwandu hwechiedza chinotaridzwa paskweya mita.
Saka, kune chiyero cheLux, iwe unofanirwa kufunga nezve nzvimbo yekamuri kana chinhambwe chemwenje sosi kubva pane imwe nzvimbo. Muchiitiko ichi, kukosha kweLux kwakapesana kune mativi pakureba. Ndiko kuti, sezvo chinhambwe chinowedzera, kukosha kweLux kunoderera. Nokudaro, chiedza chinoratidzika chakajeka muimba duku hachizotaridziki chakajeka kana chikaiswa muimba huru.
Mumashoko ebhuku, Lux inoratidzwa se- 1 lx yakaenzana ne1lm/m^2. Kureva kuti kukosha kweLux kunoenderana neLumens (lm). Saka, ngatisvetukira muLumens kuti tidzidze Lux zvirinani-
Chii chinonzi Lumen?
Kukosha kweLuminous Flux kunoyerwa neLumen (lm). Ndiro izwi rinonyanya kushandiswa kuratidza kusimba kwemwenje.
Lumens inotaura huwandu hwehuwandu hwechiedza. Kureva, kupenya kwese kunoburitswa nechiedza iLumens. Kusiyana neCandela (cd), Lumens haiverenge kuvhenekera kubva kune imwe nzira. Asi inoratidza lumens mbishi.
Iyi Lumen mbishi inoyera kupenya kwechiedza kubva kumativi ese. Somugumisiro, pasinei nechiedza chekubuda kwekona, kukosha kweLumen kunoramba kuripo.
Uyezve, kukosha kweLumen kunosiyana nerudzi rwechiedza, ruvara, uye sosi yemagetsi.
Candela vs Lux vs Lumens - Ndeipi Misiyano?
Misiyano yekutanga pakati peCandela, Lux, neLumens ndeyotevera patafura iri pazasi-
| Magadzirirwo | Candela | Lumens | Lux |
| tsananguro | Candela ndiyo chiyero chekupenya kwechiedza chechiedza pane imwe kona uye nzira. | Lumen inoratidza kubuda kwechiedza kumativi ese. | Huwandu hwekuvhenekera hunorova pa square metre nharaunda iLux. |
| Kuyera Chikamu che | Luminous Intensity | Kuvhenekesa Flux | Chiedza |
| Mucherechedzo (SI) | cd | lm | lx |
Candela ndiyo yekuyera chikamu cheLuminous Intensity. Zvichakadaro, Lumen neLux ndiwo mayuniti eLuminous Flux uye Kupenya.
Nemashoko akapfava, Candela anoratidza kuti chiedza chinopenya sei; Lux inoyera kuti chinhu chinoratidzika sei chakajeka muchiedza. Uye Lumen inoratidza iyo yakazara kuburitsa iyo mwenje sosi inopa.
Kuchinja kwechinhambwe kunokanganisa kukosha kweLumen neLux, asi Candela inoramba iripo. Izvi zvinodaro nekuti kukosha kwaCandela kunoenderana nemakona pane kureba.
Candela vs Lux vs Lumens - Vanobatana Sei?
Hukama hunonyanyozivikanwa pakati pematemu matatu aya ndewekuti ose ndiwo chiyero chekuyeresa chechiedza. Kuti tijekese pfungwa, ngatisvike pamudzi wemazwi aya-
Lumens imhando yerudzi rweCandela. Ose mazwi anoyera kupenya; kureva kuti vanotaura kupenya kwechiedza. Musiyano ndewekuti lumens inotora nhoroondo yemwenje yemwenje kubva kumativi ese. Mukupesana, Candela anofunga kuti kune imwe nzira.
Zvekare, iyo unit Lux kuyerwa kweLumen pa square mita. Icho chimiro chekutorwa kweLumens. Mumashoko esvomhu, 1 lx = 1lm/m^2. Equation iyi inopa tarisiro yechokwadi yekupenya kwechiedza kupfuura Lumens.
Uye chimwe chinhu chinonakidza ndechekuti Lux ndiyo metric vhezheni yemakenduru etsoka (izwi rekare rinoreva Candela).
| Yakatorwa kubva Kubva Lux ———————→ Lumens ——————–→ Candela 1 lx = 1 lm/m2 = 1 cd·sr/m2 |
Saka, Candela, Lux, uye Lumens zvakabatana. Asi, vanotaura zvitatu zvakasiyana, asi zvakabatana uye zvinoshandurwa.
Chikamu chakazara chine kona yakasimba ye 4π steradians, saka sosi yemwenje inopenya zvakafanana candela mumativi ese ine inopenya inopenya inoyerera.
1 cd × 4πsr = 4π cd · sr ≈12.57 lm.
Zvinhu Zvinokanganisa Kukosha KweCandela Vs. Lux Vs. Lumens
Hunhu hweCandela, Lux, uye Lumens hunochinja nekuda kwezvinhu zvinotevera:
mufambo
Nhambwe pakati pechinhu nemwenje sosi inokanganisa kukosha kweLux neLumens. Izvi zvinodaro nekuti sikweya yechinhambwe inoenzana nezvikamu izvi.
Kuwedzera hurefu nekaviri, kukosha kwelx kunoderedza kusvika 1/4th yezvakakosha zvekutanga. Asi chinhambwe hachikanganisa kukosha kweCandela, sezvo ichitamba nemakona kwete chinhambwe.
Angle Of Radiance
Kona inogadzirwa nechiedza inokanganisa kuvhenekera. Iyo idiki kona iri, iyo yakawanda kukosha kweCandela neLux; chiedza chinowedzera kupenya.
Uyezve, nzvimbo yekuvhenekera inowedzera kumakona makuru ekupenya, ichichengeta kukosha kwelm kusingachinji.
Luminous Efficiency
Kupenya kwakanaka kunoyera kugona kwechivheneko kuburitsa mwenje wakajeka. Izvo zvinoenderana neiyo simba sosi yeWattage uye Lumens chiyero. Iko kushanda kunopenya kunowedzera sezvo kukosha kweWatt kunoderera.
Ndiko kuti, iyo yakakura iyo inovhenekera kushanda zvakanaka, iyo inopenya zvakanyanya chiedza.
Ndeipi Iyo Yakajairwa Chiedza Measuring Unit Ye LED Strip?
Iyo yakajairwa mwenje yekuyeresa unit ye LED Stipe ndeye Lumens. Asi, isu tinowanzo kanganisa kuyera kupenya kwe LED mitsetse neWattage. Iyoyo itsika isina kunaka sezvo mwenje wakasiyana uine mwenje wakasiyana unoshanda.
Saka, nzira chaiyo yekutonga mashandiro emutsetse we LED ine Lumen patsoka/mita.
Nekudaro, kukosha kweLumen kunosiyana nemuvara weiyo LED mutsara. Semuenzaniso, machena e LED mitsetse ine yakakwira Lumen kukosha pane ine mavara e LED mitsetse.
MaLumens & Wattage Anoenderana Sei?
MaLumens anoratidza kuburitsa kwese kuburitswa nechiedza, nepo Wattage riri iro simba rinoshandiswa kumhanyisa mwenje. Zvakadaro, kutonga kushanda kwechiedza, iwe unofanirwa kufunga nezve kugona kwechiedza nekuziva lumen uye Wattage kukosha.
Muchiitiko ichi, magetsi ekuchengetedza magetsi ndiwo anonyanya kushanda. Nekuti ivo vanogadzira yakakwira lumen rate vachishandisa shoma simba (Wattage). Ndosaka ichinzi magirobhu ekuchengetedza simba.
Kushanda kwechiedza kunoverengerwa seLumen Per Watt. Ndizvozvo
Kushanda Kwechiedza, E = lm/W
Saka, kushanda kwechiedza kunowedzera kana kushanda kwacho kuchivandudza. Panguva imwecheteyo, mwenje wepamusoro-soro unoderedza mari yako yemagetsi.
