Ukukhanyisa kudlala indima ebalulekileyo kwi-ambiance yendawo, nokuba kusekhaya, eofisini, okanye kwindawo kawonkewonke. Xa uthenga iiglowubhu, kubalulekile ukuqonda umahluko phakathi kwegama elithi “lumens” kunye ne “kelvin” ukwenza isigqibo esinolwazi.
Umahluko omkhulu phakathi kwe-kelvin kunye ne-lumens kukuba i-kelvin ibonisa okanye inoxanduva lombala wokukhanya oveliswa yibhalbhu yesibane. Ngokuchasene noko, i-lumens kukukhanya kweso sibane esinombala esiveliswa yiglobhu yesibane. Ngelixa u-Kelvin echaza umbala okhanyayo, i-lumens ichaza ukuba ukukhanya kuya kuqaqamba kangakanani.
Ukuqonda umahluko phakathi kwala magama mabini kungakunceda ukhethe ibhalbhu echanekileyo ukudala umoya ongqongileyo ofunekayo kunye nokuphucula ukusebenza kakuhle kwamandla. Kule bhlog, siza kuntywila kumahluko phakathi kwe-kelvin kunye ne-lumens kunye nokubaluleka kwazo ekukhetheni ibhalbhu yesibane echanekileyo kwiimfuno zakho.
Wachaza uKelvin
Ubushushu obuhlukeneyo bubonisa ubukho bokukhanya kofakelo lokukhanyisa. Le mbonakalo yokukhanya iqikelelwa kuKelvin (K) kwaye ivavanywa ukuba iphakathi kwe-1,000 ukuya kwi-10,000. Uluhlu lweebhalbhu ezisetyenziswa kushishino nakwiindawo zengingqi lusuka kwi-2000 K ukuya kwi-6500 K.
Uluhlu lwemigangatho yokukhanya lubonisa inkangeleko egqithisiweyo ngelixa ukhanyisa. Ukwabela ubushushu bebhalbhu kusetyenziswa iqondo lobushushu elinxulumeneyo (CCT). Umzekelo, ubukho bokukhanya bunokufumaneka emva kokufudumala kwesinyithi kumaqondo obushushu aphezulu.
Ukutshintsha kobushushu kulungelelanisa ukuhlukahluka kwembonakalo yentsimbi, efana neblue, i-orenji, okanye ityheli. Nokuba kusenokuba njalo, inzululwazi yangaphakathi yezibane ijongana nemizekelo ethile yezinto zesinyithi ezicinga malunga nobushushu bukaKelvin.
- Ubushushu bombala ukusuka ku-2000 K ukuya ku-3000 K kwaziwa ngokuba "bumhlophe obufudumeleyo."
- Ubume obubonakalayo bokukhanya bubonisa ukuya kuthi ga kwiqondo elithile phakathi kwe-orenji ukuya kumthubi-mhlophe. Kwaye kwakhona, ukuba ubushushu obuhlukeneyo buguquguquka phakathi kwe-3100 K kunye ne-4500 K buhlelwa "njengomhlophe oshushu."
Ukukhanya okudlulisiweyo kubonakala ngathi kuluhlaza okwesibhakabhaka okanye kumhlophe ocacileyo ophakathi. Ubushushu obahlukeneyo obungaphezulu kwe-4500 K bubizwa ngokuba “yimini epholileyo.” Nokuba kunjalo, inkuthazo yokuyibiza ngokuthi "ukukhanya kwemini" kungenxa yokuba ukukhanya kulinganisa ukukhanya kwaye emva koko kunika ukukhanya okuluhlaza okwesibhakabhaka-mhlophe.
Ubushushu obahlukeneyo be-2700 K bubonwa njengelona lilungele amagumbi osapho, iingingqi zesidlo, amakhitshi kunye namagumbi. Emva koko, i-3000 K inokuthathwa njengefanelekileyo kumagumbi kunye neendawo ezivulekileyo. Ukongeza, i-5000 K okanye ngaphezulu yeyona ilungele ukukhanyisa iigaraji kunye namagumbi angaphantsi.

Lumens Icacisiwe
Izixhobo zokukhanyisa zihlala zifunyanwa emva kokujonga ukukhanya kwazo. I-Lumens ilinganisa umda wobukhazikhazi bofakelo lokukhanyisa. Igama elithi “Lumen” lithetha ukukhanya, kwaye libonakala ngokuphakathi xa umntu ezama ukuseta isifaniso ngezibane. Nokuba kunjalo, ukuqikelela isimbuku kunye nomda wezibane ze-LED ezibekwe phambili kwaziwa ngokuba yi-lumen. Okukhona i-lumen, kokukhona izixhobo zokukhanyisa ziya kuba ntle kakhulu.
Kubalulekile ukuqonda ukuba angakanani amandla asetyenziswa yi-LED okanye malunga ne-lumen. Zombini zibalulekile kwiindawo zazo. Kwimeko nayiphi na into, kubalulekile ukujonga isenzeko sokukhanya ngaphambi kokukufumana. Ukugqiba amandla ee-bulbs eziqhelekileyo, "i-wattage" yayicatshangelwa. Umbane ubonisa umda wokusetyenziswa kombane wesibane. Emva koko, yaphucula ulwazi malunga nokuqaqamba kwezixhobo. Amanzi angcono abonisa ukukhanya okuqaqambileyo.
Nangona kunjalo, umbono wobungangamsha kunye nentelekelelo yokusetyenziswa kwamandla itshintshile ngeengcango ezahlukeneyo zokukhanyisa ezivelisayo. Ngaphandle koko, i-wattage ayibonisi nto malunga nokuqaqamba kokukhanya, njengoko iilumens zinobuchule bokucacisa lo mbandela.
Ngokusebenzisa i-lumens, umntu unokugqiba ngokukhawuleza isiqwenga esipheleleyo sezibane ezifundiswe ngonyawo lwesikwere. Umzekelo, ibhalbhu eqhelekileyo inokuhambisa i-lumens eyi-1600 ngokuchaseneyo, kunye ne-100 watts, ngelixa i-LED inokufikelela kwi-lumens efanayo kunye ne-26 watts. Kungenxa yoko le nto ii-LED zithandwa ngaphezu kweebhalbhu ezikhanyayo.

Unxulumano phakathi kweLumen kunye noKelvin- Intsomi
I-Lumens kunye neKelvin zixhunyiwe; yaziwa ngumntu wonke! Inene, lowo ngumgwebo ogwenxa. Kukho unxibelelwano phakathi kwelumen kunye noKelvin, kodwa ayilulo ulungelelwaniso oluthe ngqo.
Inani eliphezulu le-lumens alithethi ukuba ubushushu beKelvin buphezulu kwaye ngokuphambeneyo. Nangona kunjalo, ubushushu bombala bokukhanya bunokuchaphazela indlela okubonakala kuqaqamba ngayo kwiliso lomntu. Ngokomzekelo, ukukhanya okupholileyo, okuluhlaza okwesibhakabhaka kunokubonakala kuqaqambile iliso kunokufudumala, ukukhanya okuphuzi kunye nenani elifanayo le-lumens.
Yintoni ebalulekileyo xa uthenga ibhalbhu- Kelvin okanye iLumen?
Xa uthenga ibhalbhu, zombini uKelvin kunye neLumen zizinto ezibalulekileyo ekufuneka ziqwalaselwe. I-Kelvin (K) ngumlinganiselo wobushushu bombala wokukhanya, ngoxa iLumen (lm) ingumlinganiselo wokuqaqamba kokukhanya.
I-Kelvin ibalulekile kuba ichaphazela i-ambience kunye nomoya wegumbi. Iibhalbhu ezinamaxabiso asezantsi e-Kelvin (2700K-3000K) zivelisa ukukhanya okufudumeleyo, okupholileyo, okutyheli okugqibelele kumagumbi okulala, amagumbi okuhlala, kunye neendawo zokutyela. Iibhalbhu ezinamaxabiso aphezulu e-Kelvin (3500K-5000K) zivelisa ukukhanya okupholileyo, okuqaqambileyo, okuluhlaza-mhlophe okulunge ngakumbi iindawo zokusebenza, amakhitshi kunye nezindlu zangasese.
ILumen ibalulekile kuba imisela ukuqaqamba kokukhanya. Ukuphakama kwe-lumen rating, kokukhona ukukhanya kuqaqambile. Isixa se-lumens oyifunayo siya kuxhomekeka kubukhulu begumbi kunye nenjongo yokukhanya. Ngokomzekelo, isibane sokufunda sinokudinga kuphela i-300-500 lumens, ngelixa igumbi elikhulu lokuhlala lingadinga i-1500-3000 lumens.
