Iilumens kunye neewatts. Ungayikhetha njani eyona bulb yokukhanya ilungileyo ekhayeni lakho

izibane kunye neewatts

Ubungakanani bokukhanya okukhutshwe yibhalbhu watts. Oku kwaphela ngokufika kwee-bulbs ze-LED. Namhlanje amandla elambu alinganiswa izibane kwaye ayikho enye into ngaphandle kobungakanani bokukhanya okuphumayo. IiWatt zisetyenziselwa ukulinganisa amandla asetyenzisiweyo. Xa sithatha isigqibo sokuthenga ibhalbhu yesibane okanye isibane kufuneka sazi la magama mabini ukuze sazi ukuba sinomdla okanye akunjalo. Kwelinye icala, kungakanani ukukhanya ezakusinika kona kuxhomekeke ekusebenziseni esifuna ukukunika kunye nokusetyenziswa kwamandla ukuze singafumani isimanga kwityala lombane.

Ke ngoko, kweli nqaku siza kukuxelela yonke into ekufuneka uyazi malunga ne-lumens kunye nendlela yokuthelekisa neewatts. Ngaba uyafuna ukufunda indlela yokukhetha kakuhle ukuba zeziphi iibhalbhu ozifunayo ekhayeni lakho? Qhubeka ufunda ukuba sikuxelela yonke into.

Yintoni i-lumens kwaye ilinganiswa njani?

iintlobo zebhalbhu kunye nokonga

Xa sithatha isigqibo sokuthenga ibhalbhu yesibane kufuneka sazi ukuba siza kusinika ukukhanya okungakanani kwaye siyisebenzisa njani. Ngaphambili bekufuneka siqikelele ukuba ngamandla alo. Ibhalbhu engama-60W ikhanya ngaphezulu kwama-25W, ngokucacileyo. Nangona kunjalo, ayingomlinganiso ngqo, kuba olinganisa i-watts ngamandla asetyenziswa ibhalbhu. Ukuba uthenga ibhalbhu ye-LED, sinokukhanyisa ngakumbi ngeewatts ezifanayo.

Ngezi zizathu ukukhanya kwazalwa. Ukwazi ubudlelwane phakathi kwe-lumens kunye ne-watts yebhalbhu yokukhanyisa ukwazi ukuba yintoni ekhanyayo kunye noko ikudlayo kunzima. Kuxhomekeka kakhulu kubuchwephesha obusetyenziselwa ukwenziwa kwayo. Iibhalbhu ezimbini ezinamanzi afanayo zinokuqaqamba ngokwahlukileyo ngenxa yendlela eziyilwe ngayo. Umzekelo, ibhalbhu yesibane esetyenziswa kancinci, i-LED okanye i-halogen ayifani nesiqhelo.

Kulapho sicelwa ukuba sifune ukwazi ukuba angakanani amandla ombane esiwafunayo kwigumbi elingenawo umbane obangela ukuba ityala lombane liphume. Nangona isifundo sokukhanyisa siyafuneka ukulungiselela ukusetyenziswa, kunokwenzeka ukuba idatha ethile ibekiwe kwikhaya lethu apho akunyanzelekanga ukuba uthathele ingqalelo ukusetyenziswa kwemilimitha.

Isifundo sokukhanyisa siqhutyelwa amaziko orhwebo, amabala ebhola ekhatywayo kunye nezinye iindawo zikawonke-wonke apho kufuneka khona ukuba kukhanyiselwe ukukhanya iiyure ezininzi ngosuku. Kulapho kufanelekileyo ukubalwa ukuya kwimilimitha inani lokukhanya okuyimfuneko ukuze uhlale kakuhle kwaye oko kunceda ukuba ungasebenzisi umbane omninzi.

Ekhaya lelinye ibali. Ke siza kufunda ukwahlula phakathi kwe-lux kunye ne-lumens kakuhle.

Yintoni i-lux xa ithelekiswa ne-lumen

izibane kunye neeluxes

Xa siza kuthenga isibane okanye ibhalbhu kufuneka sazi ukuba kungakanani ukukhanya okuya kufuneka kwigumbi esiza kulayita kulo ukuze singabinaso isibane esibi okanye singabinaso isibane esikhulu. Ubungakanani bokukhanya okufunwa ligumbi kukukhanya okuphakathi okanye i-lux. Njengesiqhelo, Amagumbi afuna ubunewunewu obuncinci ngamagumbi okulala ane150 kwaye elona linamagumbi okuhlala alikhulu elinama-300.

Ukufumana umbono wobungakanani bezinto zobumnandi ilanga elizithelekisileyo kunye nokukhanya okungekuko, sinokubona ukuba lisikhanyisela njani ngamandla phakathi kwama-32.000 kunye ne-100.000 yeelofi xa kuthelekiswa neeluxes zethu ezibuhlungu ezingama-300 kwigumbi lokuhlala.

Kwelinye icala, sinokuhamba kwamandla okusetyenziswa kwebhalbhu yesibane kwaye yile nto ilinganiswa kwizikhanyiso. Kunokuthiwa i-lux enye yenye yeemitha zesikwere somhlaba okhanyayo. Ngala maxabiso kulula ukucinga ukuba singalinganisa igumbi kwaye sazi umphezulu walo, kwaye ngenxa yoko, sithenge ibhalbhu yokukhanyisa enesibane esiyimfuneko. Nangona kunjalo, oku akulula kangako, kuba kufuneka sithathele ingqalelo ukuphakama apho siza kubeka khona ibhalbhu.

Into yokuqala ekufuneka siyazi yimfuno yegumbi lokukhanya kunye nokubeka phambili intuthuzelo. Kulilize ukuthenga ibhalbhu enesikhanyiso esisezantsi ukuze ugcine ukukhanya ukuba asizukuphila ngayo. Imibala yegumbi ikwachonga izinto xa ukhetha ukukhanya kwebhalbhu. Kwimibala ekhanyayo, siya kufuna ukukhanya okuncinci kwaye ngokuchaseneyo.

Indlela yokukhetha ibhalbhu yethu

indlela yokukhetha iibhalbhu ezikhokelwayo ekhaya

Ibhalbhu yokukhanyisa inokuza nesalathiso se "60 lumens". Ukugqibelela kodwa kubonisa ntoni oku? Abavelisi abakaqapheli ngokungazi kwabantu ngokujongana notshintsho lwamva nje kumlinganiso. Amasiko asenza sijonge kwii-watts zebhalbhu, xa ngoku sifumanise ukuba silinganisela ukusetyenziswa kwaye hayi ukuba sikhanyisa kangakanani.

Ukunceda ukufezekisa ibhalbhu efanelekileyo kufuneka siyazi loo nto Ibhalbhu ye-LED ihlala ivelisa phakathi kwe-60 kunye ne-90 lumens. Ukwazi ngakumbi okanye ngaphantsi kwe-priori ukuba leliphi ibane lokukhanya eliza kusinika ibhalbhu ye-LED ngaphambi kokuyithenga, sisebenzisa le fomyula ilandelayo:

Izibane zokwenyani = inani leewatts x 70.

70 lixabiso eliphakathi elilingana uninzi lweebhalbhu ezithengiswa kwiimarike. Le yindlela esinokuthi sigqibe ngayo Ikhoyili ye-12W ye-LED iya kuba nemveliso ekhanyayo ye-840 lumens. Iyafana nebhalbhu ye-60W incandescent eqhelekileyo. Ngelixa eliqhelekileyo lisebenzisa amandla angama-60W, i-LED ikhanya ngokufanayo, inamandla e-12 W.

Ukuba sithathe isigqibo sokutshintsha iibhalbhu zokukhanya endlwini yethu, siza konga i-48W ngebhalbhu nganye, malunga. Enye yeengxaki ezibonelelwa kukukhanyisa kwe-LED yindawo yokuvula enikezelwa kukukhanya. Ukwazi konke oku kungcono ukuba ujonge kwinkcazo kunye nokusetyenziswa okucetyiswayo ngumvelisi oza kwibhokisi yokuthenga. Ngale ndlela sinokuziqhelanisa ngcono neemeko ezilungele thina okanye hayi.

Iindaba ezimnandi zezokuba itekhnoloji ye-LED iphucula yonke imihla, ke sele bekwazi ukukhanyisa amagumbi amakhulu ngebhalbhu enye yokukhanya.

Ndiyathemba ukuba ezi ngcebiso zikunceda ukuba ukhethe ngcono ibhalbhu efanelekileyo yokusebenzisa ikhaya.
