Ngesikhathi sokukhuphuka kwezindleko zezinsizakusebenza, abantu abavamile bezindlunkulu bazibuza ukuthi bangakanani ugesi 'abadla' izinto ezivamile nezindlu ezijwayelekile: i- efrijini , i-oven microwave, umshini wokuwasha, insimbi, ikhompyutha. Kodwa, ubona, idivayisi ethandwa kakhulu iveza isithakazelo esikhethekile, umngane wasemanzini wemindeni eminingi - i-TV. Akuyona imfihlo ukuthi emikhayeni eminingi "isikrini esibhakabhaka" sisebenza kusukela ekuseni kuze kube kusihlwa / ebusuku. Ngaphezu kwalokho, amakhaya amaningi awasebenzisi ngisho ne-TV eyodwa, kodwa amaningana: ekhishini, ekamelweni lokulala.
Kufanelekile ukuphawula ukuthi ama-TV anesiphakamitha esichaza inani lombane ukuthi idivayisi isebenzisa ngehora lokusebenza okuqhubekayo, ukusetshenziswa kwamandla, noma ukusetshenziswa kwamandla. Ngakho-ke, sizokutshela ukuthi i-TV yezinhlobo ezahlukene idla amandla kangakanani.
Iyini ukusetshenziswa amandla kwe-TV?
Kunengqondo ukuthi ukusetshenziswa kwamandla kwe-TV kuncike ezimeni eziningi. Lokhu, isibonelo, ubukhulu bedivayisi, ukubukeka kwayo, imisebenzi eyengeziwe nezinketho, kanye nokukhanya kwesithombe esiboniswe ngumnikazi.
Ngendlela, amandla we-TV ibalwa ku-watts, noma i-W encane, inwetshwe yisikhathi sokusebenza - W / h.
Ngokwezinga elikhulu, ukusetshenziswa kwamandla kunqunywa uhlobo lwe "idivayisi eluhlaza okwesibhakabhaka". I-CRT yanamuhla ene-cathode ray tube idla ama-watts angu-60 kuya kwangu-100 ngehora (kuye ngokuthi ubukhulu be-kinescope). Uma, isibonelo, ubukela i-TV enjalo nsuku zonke amahora amahlanu ngosuku, njalo usuku olutshiswa yile divayisi luzoba yi-0.5 kW / h, nenyanga - 15 kW / h.
Manje ake sikhulume ngezinye izinhlobo zeTVs zanamuhla.
Okukhulu kunabo bonke abavela "abafowethu" abancane amandla e- TV yama- plasma. Ukusebenzisa amandla kwedivaysi nge-diagonal enkulu kufinyelela ku-300-500 watts ngehora. Njengoba ubona, isikrini se-plasma sidla i-1, 5-2.5 kW ngosuku ngokubuka amahora amahlanu, futhi, ngokufanayo, i-45-75 kW ngenyanga. Vumelana, okuningi. Kodwa, izinga lokukhiqiza umbala we-TV ye-plasma ezingeni eliphakeme kakhulu!
Uma sikhuluma mayelana nokusetshenziswa kwamandla kwe- LCD TV , lesi sibalo sincane kakhulu. Idivaysi ene-20-21 diagonal idla 50-80 W kuphela ngehora, futhi, ngokufanayo, i-0, 25 kW / h ne-7.5 kW ngenyanga. Ukulondoloza kusobala! Noma kunjalo, amadivaysi ane-diagonal enkulu asebenzisa ugesi amaningi - 200-250 watts ngehora.
Ngendlela, ukusetshenziswa kwamandla kwe- TV ye- LED ngenxa yokusetshenziswa kwe-diodes e-backlight ngokuvamile ku-30-40% ephansi kunayo ye-TV ejwayelekile ye-LCD.
