Kungani Ama-Lumens Ebalulekile Ezicelweni Zokukhanyisa Emgwaqweni?

Uma ukhetha izibani zasemgwaqweni, ukuphuma kwe-lumen kungenye yezindlela zobuchwepheshe ezibaluleke kakhulu okufanele uziqonde. Ama-lumen alinganisa inani eliphelele lokukhanya okubonakalayo okukhishwa umthombo wokukhanya. Ngokungafani ne-wattage, ekhombisa ukusetshenziswa kwamandla kuphela, ama-lumen abonisa ngqo ukuthi ukukhanya komgwaqo kukhanya kangakanani ngempela.

Esikhathini esidlule, amandla okukhanya ayevame ukusetshenziswa njengereferensi yokukhanya. Kodwa-ke, ngokusetshenziswa kabanzi kwezibani zasemgwaqweni ze-LED, le ndlela ayisanembile. Ubuchwepheshe be-LED bungakhiqiza ukukhanya okukhulu kakhulu ngokusetshenziswa kwamandla okuphansi. Ngakho-ke, izibani zasemgwaqweni ezimbili ezinamandla okukhanya afanayo zingase zibe nemiphumela ehlukene kakhulu ye-lumen kanye nokusebenza kokukhanya.

Ekusetshenzisweni kokukhanyisa emgwaqweni, izidingo ze-lumen ziyahlukahluka kuye ngohlobo lomgwaqo, ukuphakama kokufakwa, kanye nesikhala phakathi kwezinsika. Imigwaqo yokuhlala ngokuvamile idinga ukuphuma kwe-lumen okuphansi ukuze inikeze ukukhanya okukhululekile nokulinganayo ngaphandle kokukhanya okukhanyayo, kuyilapho imigwaqo emikhulu, imigwaqo emikhulu, kanye nezindawo zezimboni zidinga amazinga aphezulu e-lumen ukuqinisekisa ukubonakala nokuphepha kwezimoto nabahamba ngezinyawo. Ukukhetha i-lumen efanele kusiza ekufinyeleleni ukukhanya okwanele ngenkathi kugwenywa ukungcola kokukhanya ngokweqile kanye nokusetshenziswa kwamandla okungadingekile.

Kubalulekile futhi ukuhlukanisa phakathi kwama-lumen enkolelo-mbono nama-lumen asebenzayo. Eminye imikhiqizo emakethe ithi amanani aphezulu kakhulu e-lumen abalwa ngokusekelwe kudatha ye-chip ye-LED kuphela, ngaphandle kokucabangela ukulahlekelwa okuvela kumshayeli, ilensi yokukhanya, kanye nokushabalaliswa kokushisa. Ezimweni zangempela zokusebenza, ama-lumen angempela angasetshenziswa angaba phansi kakhulu. Abakhiqizi abathembekile banikeza idatha ye-lumen ngokusekelwe ekuhlolweni kwangempela, okubonisa kangcono ukusebenza kwasendaweni.

Ukusebenza kahle kwe-Lumen, okuvame ukuvezwa njenge-lumens nge-watt (lm/W), kungenye into ebalulekile. Inani eliphakeme le-lm/W lisho ukuthi ukukhanya komgwaqo kukhiqiza ukukhanya okwengeziwe ngamandla amancane. Izibani zomgwaqo ze-LED ezisebenza kahle kakhulu azigcini nje ngokunciphisa izindleko zikagesi kodwa futhi zivumela amaphaneli elanga amancane namabhethri ezinhlelweni zokukhanyisa komgwaqo welanga, okuthuthukisa ukuzinza kohlelo lonke kanye nokusebenza kahle kwezindleko.

Ngokuqondene nezibani zasemgwaqweni zelanga, ukwakheka kwe-lumen efanele kubalulekile. Ukukhishwa kwe-lumen okukhulu kakhulu kungabangela ukusetshenziswa kwamandla ngokweqile kanye nokuzimela okwanele kwebhethri phakathi nezinsuku ezinamafu noma zemvula. Uhlelo oluklanywe kahle lulinganisela ukuphuma kwe-lumen kanye nomthamo wephaneli yelanga, isitoreji sebhethri, kanye nezimo zokukhanya kwelanga zendawo ukuqinisekisa ukusebenza okuthembekile nokwesikhathi eside.

Ekuphetheni, ama-lumen ayinkomba enembile nenenjongo yokusebenza kwezibani zasemgwaqweni kune-wattage. Ukuqonda ukuphuma kwe-lumen, ukusebenza kahle, kanye namanani angempela avivinyiwe kusiza abathengi nabanikazi bephrojekthi ukuthi benze izinqumo ezinolwazi, bafinyelele ukukhanya komgwaqo okufanele, futhi bagweme izimangalo zomkhiqizo ezidukisayo. Ukukhetha izibani zasemgwaqweni ezinemininingwane efanele neqinisekisiwe ye-lumen kuqinisekisa ikhwalithi yokukhanya engcono, isikhathi eside sokuphila, kanye nenani eliphakeme lephrojekthi iyonke.
