Inani lokukhanya elikhishwe isibani ama-watts. Lokhu kuphele ngokufika kwama-LED. Namuhla amandla elambu alinganiswa ngo amalambu futhi akukho okungaphezu kokukhanya okukhiphayo. Ama-Watts asetshenziselwa ukukala amandla asetshenzisiwe. Lapho sinquma ukuthenga isibani noma ilambu kudingeka sazi lemiqondo emibili ukuze sazi ukuthi sinentshisekelo noma cha. Ngakolunye uhlangothi, kuzosinikeza ukukhanya okungakanani kuye ngokusetshenziswa esifuna ukukunika kona nokusetshenziswa kwamandla ukuze singatholi isimanga enkokhelweni kagesi.
Ngakho-ke, kule ndatshana sizokutshela konke odinga ukukwazi ngamalambu nokuthi ungawaqhathanisa kanjani nama-watts. Ngabe ufuna ukufunda ukuthi ukhetha kanjani kahle ukuthi yimaphi ama-bulb owadingayo ekhaya lakho? Qhubeka ufunde ukuthi sikutshela konke.
Ayini amalambu futhi alinganiswa kanjani?
Lapho sithatha isinqumo sokuthenga isibani esikhanyisayo kudingeka sazi ukuthi sizosinika ukukhanya okungakanani nokuthi sidla malini. Phambilini, bekufanele silinganise lokho ngamandla ayo. Isibani esingu-60W sikhanya ngaphezu kuka-25W, kusobala. Kodwa-ke, akusona isilinganiso ngqo, ngoba empeleni ama-watts angalinganisa amandla asetshenziswa yi-bulb. Uma uthenga isibani se-LED, singakhanyisa kakhulu ngama-watts afanayo.
Ngalezi zizathu amalambu azalwa. Ukwazi ubudlelwano phakathi kwamalambu kanye nama-watts ebhalbhu elikhanyayo ukwazi kokubili ukuthi kukhanya ini nokuthi kudlani kuyinkimbinkimbi ngandlela thile. Kuya kakhulu kubuchwepheshe obusetshenziselwa ukwenziwa kwabo. Ama-bulb amabili ane-wattage efanayo angakhanya ngokuhlukile ngenxa nje yendlela aklanywe ngayo. Isibonelo, isibani sokukhanya esisebenzisa kancane, i-LED noma i-halogen ayifani nejwayelekile.
Yilapho sicelwa khona ukuthi sifune ukwazi ukuthi singakanani amandla kagesi esiwadingayo ekamelweni elingenawo ugesi okudala ukuthi isikweletu sikagesi sikhuphuke kakhulu. Yize isifundo sokukhanyisa sidingeka ukukhulisa ukusetshenziswa, kungenzeka ukukhipha enye idatha ekhaya lethu lapho akudingekile kangako ukucabangela ukusetshenziswa kumamilimitha.
Ucwaningo lokukhanyisa lwenzelwa izindawo zezentengiso, izinkundla zebhola nezinye izindawo zomphakathi lapho kudingeka khona ukuthi kube nokukhanya kokuzenzela amahora amaningi ngosuku. Yilapho-ke lapho kufanelekile ukubala kumamilimitha inani lokukhanya okudingekayo ukuze uhlale kahle futhi okusiza ukungasebenzisi ugesi omningi.
Ekhaya kungenye indaba. Ngakho-ke sizofunda ukuhlukanisa phakathi kwe-lux ne-lumens kahle.
Yini i-lux kuqhathaniswa ne-lumen
Uma sizothenga isibani noma isibani sidinga ukwazi ukuthi kungakanani ukukhanya okuzodingeka egumbini esizolikhanyisa ukuze singabi nokukhanya okubi noma singabi nokuningi kakhulu. Inani lokukhanya igumbi elikudingayo ukukhanyisa okujwayelekile noma i-lux. Njengenjwayelo, Amakamelo adinga ukunethezeka okuncane amakamelo okulala anama-150 kanti elinegumbi lokuhlala elinama-300.
Ukuthola umbono wenani likanokusho ilanga eliqhathanise nokukhanya okufakelwayo, siyabona ukuthi lisikhanyisa kanjani ngamandla aphakathi kwamalobolo angama-32.000 kuya ku-100.000 uma kuqhathaniswa namalobolo ethu adabukisayo angama-300 asendlini yokuphumula.
Ngakolunye uhlangothi, sinokuhamba kwamandla okusetshenziswa isibani sokukhanya futhi yilokho okulinganiswa ngamalambu. Kungashiwo ukuthi i-lux eyodwa iyinkanyiso eyodwa ngemitha eyisikwele ngayinye ekhanyayo. Ngalezi zindinganiso kulula ukucabanga ukuthi singalinganisa igumbi futhi sazi ingaphezulu lalo futhi, ngenxa yalokho, sithenge isibani esikhanyayo esinokukhanyisa okudingekayo. Kodwa-ke, lokhu akulula kangako, ngoba kufanele futhi sicabangele ukuphakama esizobeka khona isibani.
Into yokuqala okufanele siyazi isidingo segumbi lokukhanya nokubeka phambili induduzo. Akusizi ngalutho ukuthenga isibani esinokukhanyisa okuphansi ukuze wonge isibani uma singeke siphile kahle ngaso. Imibala yegumbi nayo inquma izinto lapho ukhetha ukukhanyisa kwesibani. Ngemibala elula, sizodinga amalambu amancane futhi okuphambene nalokho.
Ungayikhetha kanjani isibani sethu
Igilobhu yokukhanyisa ingahle ifike ngesibonisi se- "60 lumens". Iphelele kepha lokhu kukhombisani? Abakhiqizi abakaqapheli ukungazi kwabantu okungenzeka babheke ushintsho lwamuva nje kukalo. Amasiko asenza sibheke ama-watts ebhalbhu, lapho manje sesithole ukuthi sikala ukusetshenziswa kuphela hhayi ukuthi sikhanyisa kangakanani.
Ukusiza ukufeza isibani esiphelele kufanele sikwazi lokho Isibani se-LED ngokuvamile sakha amalambu aphakathi kuka-60 no-90. Ukwazi okungaphezulu noma okuncane i-priori ukuthi yimaphi amandla amancane isibani se-LED esizosinika wona ngaphambi kokuwathenga, sisebenzisa ifomula elandelayo:
Amalambu wangempela = inani lama-watts x 70.
70 inani elilinganisiwe elifana neningi lama-bulb athengiswa ezimakethe. Le yindlela esingakuqonda ngayo lokho ikhoyili ye-12W ye-LED izoba nokukhipha okukhanyayo kwamalambu angama-840. Lokhu kuyefana nebhalbhu ejwayelekile ye-60W incandescent. Ngenkathi okujwayelekile kudla amandla angama-60W, i-LED ikhanya ngokufanayo, ngamandla we-12 W.
Uma sinquma ukushintsha ama-light endlini yethu, sizokonga ama-48W ngebhalbhu ngayinye, cishe. Enye yezinkinga ezinikezwa ukukhanya kwe-LED yi-angle yokuvula enikezwa ukukhanya. Ukwazi kahle konke lokhu, kungcono ukubheka imininingwane nokusetshenziswa okunconywe ngumenzi oza ebhokisini lokuthenga. Ngale ndlela sizokwazi ukuziqondisa kangcono ezimeni lapho kusilungele khona noma cha.
Izindaba ezimnandi ukuthi ubuchwepheshe be-LED buyathuthuka nsuku zonke, ngakho-ke sebevele bekwazi ukukhanyisa amakamelo amakhulu ngebhalbhu elilodwa nje lokukhanya.
Ngiyethemba lawa macebiso akusiza ukuthi ukhethe kangcono isibani esilungile sokusetshenziswa kwasekhaya.
