Umhlahlandlela Wokuthenga Wakamuva Wokukhanya Okuphansi

Uma kuziwa ekukhanyeni, kunezinketho eziningi ezahlukene laphaya emakethe. Omunye wemithombo yokukhanya edume kakhulu amalambu aphansi. Ukukhanya okuphansi kuyahlukahluka ngokuya ngesicelo, izinto ezibonakalayo, kanye nokucaciswa. Abathengisi kudingeka babe nolwazi futhi banikeze izeluleko ezifanele ngokusekelwe ezidingweni zamakhasimende. Lesi sihloko sizohlomisa abathengi bebhizinisi ngalokho okudingeka bakwazi ngokuthengisa izibani ezifanele.

Ayini ama-downlights?

Amalambu aphansi ayaziwa nangokuthi amalambu aphelile, amalambu asebhodweni, noma amalambu e-can. Ziyisinqumo esihle sokusebenzisa njengezibani zophahla emakhishini okuhlala nasezindlini zokugezela; noma ezindaweni zezentengiselwano, njengasemahhovisi, ezitolo, nasemahhotela. Ziyakwazi ukuzivumelanisa nezimo futhi zingasetshenziselwa kokubili izikhala zangaphakathi nezangaphandle. Zithandwa kakhulu njengoba zinikeza ukukhanya okujwayelekile okufudumele, zingasebenza ukukhanya kwe-ambient, zonga isikhala ngenxa yobukhulu bazo, futhi zivumelane nophahla oluphansi.

Ungakhetha kanjani ama-downlights angcono kakhulu ongawathengisa?

Color lokushisa

Nawa amathiphu aphezulu abathengi okudingeka bawacabangele lapho bekhetha umbala wezibani eziphansi ekhaya. Ezindaweni ezivame ukushisa (isb. ikhishi negumbi lokuwasha), nikeza amakhasimende ukuthi azifake izibani ezipholile ezinombala omhlophe. Ngakolunye uhlangothi, ezindaweni lapho ufuna ukwakha umuzwa ofudumele nosondelene, njengegumbi lokuphumula namagumbi okulala, ukukhanya okufudumele kombala omhlophe kufanele kube inketho enkulu.

Ezindaweni zezentengiselwano ezifana namahhovisi, kungcono ukuthola umbala omhlophe opholile wemizwa ekhanyayo nenamandla. Phakathi naleso sikhathi, amahhotela, lapho abantu bangathanda khona umuzwa ofudumele, kufanele bathole ukukhanya okufudumele noma umbala omhlophe ofudumele. Noma nini lapho ungabaza, ukubheja okuphephile ukuthola okumhlophe kwemvelo 4000K, ngokuvamile elungele zonke izinhlobo zezindawo.

I-angle ye-Beam

I-engeli ye-beam ye-bulb isho ukuthi umsebe wayo wokukhanya ubanzi noma uncane kangakanani. A ugongolo oluncane (ama-20-40 degrees) afanele ukugqamisa indawo noma into, ikakhulukazi ukukhanyisa kwe-accent. Ilungele amahhotela, izitolo, kanye amahhovisi lapho abantu befuna ukugqamisa umkhiqizo noma umhlobiso.

Amalambu aphansi ane-engeli engu-25 degree beam afanele amakhishi njengoba anganikeza abantu ukukhanya okugxilile ngenkathi bepheka. Ukuze uthole ukukhanya okuthambile okusabalalisayo egumbini lokuhlala, ama-degree angama-60 we-engeli ye-boam alungile. Ngokuphambene, a ugongolo olubanzi, ngokuvamile ebhekisela kumadigri angu-100-120, ifanele izinjongo ezijwayelekile.

I-lumens kanye ne-wattage

Ngokufanayo nezinga lokushisa lombala, izinga lokukhanya lesibani lingenza umehluko omkhulu ekubukekeni nasekuzizweni kwegumbi. I-Lumen (lm) iyunithi yokulinganisa ukukhanya kwelambu lokukhanya. Isibani se-incandescent esingu-60-watt siyafana nesibani se-LED esinama-watts angu-8-12 no-800 lm. Ngokusetshenziswa okuvamile ekhaya noma ezindaweni zentengiso, i-lumen ibalwa phakathi 300 futhi 800 lm kufanele kube ukukhetha okuphephile.

Ukubekwa

Ngemva kokuhlola ukukhanya kokukhanya, okunye okucatshangelwayo yibanga eliphakathi kokukhanya ngakunye. Ukuzibeka eduze kakhulu kungaholela ekukhanyeni okungahambisani. Ukuhlukanisa amalambu aphansi ngokulinganayo kuqinisekisa ukuthi ukukhanya kukhululekile futhi akuphazamiseki.

Futhi, cabangela ama-engeli e-beam lapho unquma isikhala phakathi kwawo. Uma usebenzisa i-beam ebanzi, beka ukukhanya okuphansi ngo-1.2 kuya ku-1.5 m ngokuhlukana (cishe amafidi angu-3 amayintshi angu-11 ukuya ku-5); uma usebenzisa ugongolo oluwumngcingo, zama ukuzibeka endaweni eyi-1 m (cishe amafidi amathathu namayintshi amathathu) ukusuka kwenye.

Inkomba yokunikeza umbala (CRI)

Inkomba yokunikeza umbala (CRI) isho ikhono lomthombo wokukhanya lokubonisa imibala yezinto ngokwethembeka uma kuqhathaniswa nokukhanya kwelanga okungokwemvelo. Ikalwa ukusuka ku-0 kuye ku-100. I-100 isho ukuthi imibala engaphansi kokukhanya iyafana njengoba ibingenza uma ingaphansi kokukhanya kwelanga okungokwemvelo. Ngokuvamile, 80 kuya ku-90 CRI ingabonisa ukunikezwa kombala okunembile.

Izibani ezilinganiselwe ngomlilo

Kungakhathaliseki ukuthi izibani eziphansi zifakwa kuphi, umthetho wesithupha uthi: ukuphepha kubaluleke kakhulu. Ngokuvamile, zonke izibani ezikhanyayo ziyahlolwa futhi zihlangabezane nezindinganiso zokuphepha komlilo. Ukuvikelwa okwengeziwe kungenza umehluko omkhulu uma kwenzeka umlilo, ngakho ukukhetha ukukhanya okulinganiselwe ngomlilo Kunconywa.

Isiphetho

Kukhona ezinye izinto eziningi okufanele uzicabangele lapho unikeza abathengi iseluleko ngokukhetha ukukhanya okuphelele. Isibonelo, izindonga ezinemibala emincane zibonakala zikhanya futhi zikhanya kangcono kunezindawo ezimnyama nezimunca ukukhanya. Elinye icebiso liwukucabangela ama-dimmers aneleveli yokukhanya anezibani eziphansi ukuze wonge ugesi. Qiniseka ukuthi ziyahambisana nezinye futhi usebenzise i-push-button dimmer.

Ukuthenga ngezinhlobo ezifanele zokukhanya phansi kwekhwalithi nokunikeza iseluleko esinolwazi kuzosiza ukuheha amakhasimende futhi kuthuthukise ibhizinisi lakho. Ukuze uthole ulwazi olwengeziwe mayelana nezibani eziphansi zekhwalithi, shaya u- Chovm iwebhusayithi ukuthola abathengisi nabakhiqizi abaqinisekisiwe.
