Ukuthenga iibhalbhu zokukhanya ezazisetyenziselwa ukuba kube lula kakhulu: izixhobo zokukhanya zibhalwe kuluhlu olunamanzi amaninzi kwaye abathengi banokuthenga nje ibhalbhu ehambelanayo. Hayi kwakhona. Ukukhanya okutsha kwe-LED, i-CFL, kunye nokunye ukukhanya okusebenzayo kwamandla kutshintshe ngokupheleleyo amaxabiso ombane okanye ukujonga inkqubo yokulinganisa ngokupheleleyo. Nasi isikhokelo esiluncedo sokukhanyisa ukukhanya ngendlela yokukhetha ibhalbhu efanelekileyo yokukhanya kule minyaka intsha.
Ngokwesiko iibhalbhu zesibane se-incandescent zilinganiswe phakathi kwe-40 ukuya kwi-100 watts. Xa kuthelekiswa, i-bulb entsha ye-LED okanye ibhalbhu ye-CFL iza ixhotyiselwe i-watts ezintlanu ukuya kwezi-15. Inkqubo ye- Umbutho wezibane zaseMelika (I-ALA) icacisa ngokulula ukuba kutheni kukho ukungangqinelani kwindlela iibhalbhu zokukhanya ezibhalwe ukuba zinamanzi ombane:
Ithetha ntoni i-10-10
Isizathu soku kungangqinelani kukuhamba kwamanzi kukuxelela ukuba ibhalbhu isebenzisa amandla angakanani. Kwaye ekubeni ii-bulbs ze-LED ezintsha kunye ne-CFL zisebenzisa amandla amancinci, amanzi ombane asezantsi kakhulu.
Ke ngoko, iilebheli ezidweliswe kwizibane ezindala ezingasasebenziyo azihambelani ngokuthe ngqo kunye nokulinganiswa kwebhalbhu yokukhanya yamandla amatsha asebenza ngamandla. Ke, yeyiphi indlela echanekileyo yokutshatisa ibhalbhu entsha enezibane kunye nezinto ezilungisiweyo namhlanje? Izibane .
Izibane Yimitha yokuqaqamba, ebonelela ngemilinganiselo esebenzayo ngakumbi ekubhekiseni kuyo ngokwemigangatho yangoku. Nantsi itshathi efanelekileyo evela kwi-ALA ebonelela ngokuthelekisa ngokuthe ngqo phakathi kokukhanya kwe-LED okanye ibhalbhu yesibane yeCFL xa kuthelekiswa neebhalbhu ezindala ze-incandescent.
Gcina Ncamathisela (Ityala lemifanekiso: Unyango lweNdlu)
Uguquko oludweliswe apha ngasentla ayizizo ezona zilula ukuzibophelela kwimemori. Ngethamsanqa, abavelisi ngokubanzi baphawula iibhalbhu ezintsha ze-LED kunye ne-CFL ngokuguqula amanzi ngaphambili okanye ngasemva ekupakisheni. Gcina ukhumbula nangona uguquko ludibene nemveliso yokukhanya.
Amanani amaninzi, ngoko ke sincoma ngokubanzi ukucinga nge-1,000 lumens njengesiseko, esilingana nebhalbhu yemveli ye-60 watt. Nawuphi na umgangatho ophakamileyo okanye osezantsi uhlengahlengisa ukuqaqamba, ke khetha ngokufanelekileyo.
