Ukukhetha izibane: zingaphi lumens watt eewathi ibhalbhu 100 nganye?

Mithambo (ekubhobhozeni ezikhanyayo) yi iyunithi lomlinganiselo SI - International System of Units. Eli xabiso ukukhanya, zibonakaliswe "lumens" okanye lm.

izibane replacement

Ukubala Kudala lubonise ukuba isibane yale igqengezelayo - akukho ndlela inokusetyenziswa ngokukuko ukukhanyisa, ingakumbi xa kufikwa iindawo ezinkulu. isabelo yengonyama lwamandla alukho zokukhanya kunye ngokushushubeza olu cingwana, nto leyo eyenza ukuba ibhalbhu ilayite ngakumbi njenge heater.

Ngoku umbuzo lwamandla elinemveliso kubaluleke kakhulu, kwisithuba yokusebenzisa ophezulu lwezibonelelo kunye, okubaluleke kakhulu ukuba abathengi, amaxabiso aphezulu kakhulu eziluncedo. Ngoko ke, xa uthenga kufuneka sinikele ingqalelo ukuba amandla, kulinganiswa Watts, yaye uyabukhanyisela njani ukukhanya okukhulu. Kwaye nje le iparameter kwatshintsha lumens.

lumens Zingaphi watt eewathi bulb 100 nganye

izibane ezinjalo ezininzi eziqhele ukusetyenziswa kwezakhiwo zokuhlala. Balirhola izibane omhle elungileyo nezisemgangathweni umbala wamehlo. Ekubeni Lumens abonisa njani ukukhanya okukhulu ukhutshiwe yi umthombo, kokukhona ixabiso, i mhlophe ukukhanya. Nangona kunjalo, la manani zisenokwahluka ngokubanzi, ingakumbi xa kufikwa iintlobo ezahlukeneyo, kwanezibane. Kunzima ukubala ukuba zingaphi lumens kwi yale igqengezelayo isibane 100 watts. Umzekelo, isibane watt-20 inika ekubhobhozeni ukukhanya lumens 250, kwaye xa kabini amandla, la manzi aya kufikelela 400 lm. Kodwa ibhalbhu eneewatt-60 ngesantya 700 lumens, 900 lumens alinganayo amandla 75 watts. I-flow amandla 1200 lumens yokukhanya kuyafikelelwa ukuba amandla izibane ntambo watts 100.

Maxa wambi, abantu sebeqala ukuba bacinge malunga nendlela ukonga umbane, ngokuba inkqubela na ukuma. Okokuqala zeza kwezibane ezonga umbane, apho, ngokutsho kumenzi, kunciphisa ukusetyenziswa amandla amaxesha amabini okanye amathathu. Ke ngoku kukho iibhalbhu kakhulu amafutha-efanelekileyo - LED. Zabo kuphela ezimbi - ixabiso kakhulu phezulu, ngoko loo ngxaki iphambili kukuba isibane entsha ibandakanyiwe kwaye power amancinane, kwaye ukukhanya kwesibane zigqengezelayo.

nenkohliso

lights LED Ndawaphelisa amandla izihlandlo ezininzi kangako, kodwa ulwazi kumenzi, ngokufuthi kuphazamisa umthengi. Umzekelo, ndithi isibane efana watt-70 ibhalbhu ukukhanya kunye lumens 500, kodwa ayikwazi yinyaniso. Ukuze ukuba iphutha kunye ukhetho, kufuneka sikhumbule lumens ezininzi njani i isibane yale igqengezelayo 100 watts.

Emva kokuba kuthengwe le nto umntu badanile, ngokuba ukukhanya kungekho ngokwaneleyo kwaye kufuneka utshintshe kwi isixhobo esinamandla ngakumbi, nto leyo ehambisana kunye neendleko ezongezelelweyo, ingakumbi ukuba kusetyenziswa ibhalbhu zaye zathengwa ukuze yonke chandelier. Noko ke, xa utshintsho kuyimfuneko ukunikela ingqalelo kuphela ubungakanani efana lumens. ekubhobhozeni liqaqambileyo / amandla - oku ratio kwi-International System of Units (SI), ekuthiwa ukusebenza ezikhanyayo. Ngamafutshane, le parameter ibonisa indlela ukukhanya iziphumo 1 Watt komthombo ukukhanya. Ulinganiswa lumens watt nganye.

Indlela ukukhetha?

Kuthathelwa ingqalelo zonke parameters, kufuneka ucinge nje kuphela zingaphi lumens watt eewathi isibane 100 nganye, kodwa imveliso ukukhanya, nto leyo ilingana 100 watt 13.8 lm / W. Umzekelo: i parameter inye iibhalbhu LED nga ukusuka 10 ukuya 300 LM / W (!).

Enye inzuzo ambiwa ke elubala le glasi cingwana isibane kunye engile beam ukunwenwa degrees 360. Ngoko, xa utshintsha kwezinye iintlobo (umzekelo, i-engile LED isibane kabini ngaphantsi) ukuze bokugcinwa ukuthotywa sokukhanyisa. Ngaphezu koko, yinto isibane yale igqengezelayo ezilungele dimmers ukuba ukwazi ukulawula nje kuphela ukukhanya, kodwa ukusetyenziswa yamandla.

iilebhile

Njengomgaqo, ulwazi lumens ezininzi kangakanani watt eewathi isibane 100 nganye, lungafumaneka kwi kwiipakethe. Ukongeza, kukho zibhalwe kwakhona iparameters ezibalulekileyo ezifana isalathisi lobushushu umbala kunye nombala weklayenti (liqu), ilungelo lokukhetha kulo, ungafumana i ingenankathazo amehlo ngumthunzi ukukhanya.

lobushushu Umbala yale igqengezelayo wesiNtu Isibane 2800 K (kulinganiswa ngokwamazinga Kelvin). Eli xabiso kwaye kufuneka bakhokelwe kakhulu ekukhetheni umbala ukukhanya, Kakade, ukuba yokuhlala. Kuba izithuba zokusebenza (ii-ofisi, izibhedlele, kwiikhemesti, ezivenkileni) iithowuni afanelekileyo cala kunye lobushushu umbala we-4000 ukuya 5000 K, neegalari kunye namaholo mboniso Kucetyiswa ukuba agubungele ukukhanya ezibengezelayo (5000 K kunye nangaphezulu).

ukuchana

Ukuba nangasiphi na isizathu kubalulekile ukuba izibane xa indawo isibane uhlala kanye kwinqanaba elifanayo, ingaba imveliso ukukhanya pre-kulinganiswa isixhobo ezikhethekileyo - imitha ukukhanya. Suite - umlinganiselo umlinganiselo lumens kunye Area (1 spiderman ilingana mithambo omnye kwi square metre nganye). Ngokuqhelekileyo oku kusebenza kumaziko ahlukeneyo, apho kuyimfuneko ukuba esweni ukuthotyelwa kwemimiselo izibane karhulumente.

Namasu Efficiency Energy

Enye amacebiso umdla ukusuka iingcali kukuba ukusebenzisa izibane kwamandla ezahlukeneyo. Umzekelo, ukuba ukhanyiso enamandla ngaphezu efunekayo kwindawo yokusebenza kwelo gumbi, kwaye kwezinye iindawo kunokwenzeka ukulawula inani elingaphantsi abandwendweli. alunywe Second - utshintshe nje Yahlula ze izibane. Le iqhinga akuyi kuphela sebenzisa amandla encinane, kodwa kwakhona ukuba ukwabelana band kwi kwigumbi studio okanye amagumbi amakhulu.
