Izindleko Ezifihliwe: Kungani Amadivayisi Abomvu Ashibhile Egcina Ebiza Kakhulu

Lokho Amadivayisi Ashibhile Angakutsheli Khona

Ukwelashwa kokukhanya okubomvu kwezokwelapha kudinga ubude obuqondile bamaza—ngokuvamile okungu-630-670nm kokukhanya okubomvu kanye no-810-850nm kokukhanya okuseduze kwe-infrared. Amadivayisi ashibhile asebenzisa ama-LED ajwayelekile abonakala ebomvu kodwa angenabo ubumsulwa be-spectral amangqamuzana akho adinga ukusabela. Emehlweni akho, kubukeka kufana. Emaseli akho, akubonakali.

I-Power Mirage

Ubuningi bamandla bunquma ukuthi ukukhanya kufinyelela yini ekuhlosweni kwakho—isikhumba, imisipha, noma izicubu ezijulile. Abakhiqizi abangabizi kakhulu bavame ukufutha imininingwane yabo, ngezinye izikhathi ngesilinganiso seshumi. Okubi nakakhulu, ama-LED ashibhile ayancipha ngemva kwamahora angu-500 kuya ku-1,000 okusetshenziswa. Iphaneli yokwelapha yokukhanya okubomvu yobungcweti evela kumkhiqizi odumile igcina umkhiqizo ozinzile amahora angu-30,000 kuya ku-50,000.

Ukugembula Kokuphepha

Izitifiketi ezifana ne-IEC 60601-1 zemishini kagesi yezokwelapha zibiza imali ukuzithola. Abakhiqizi abashibhile bayazeqa. Ngeke wazi kuze kube yilapho idivayisi ikhubeka ku-circuit breaker yakho, ikhiphe iphunga elivuthayo, noma, ezimweni ezimbi kakhulu, iba yingozi yomlilo yangempela.

Ukwesekwa Okungenalutho

Uma idivayisi eshibhile ihluleka—futhi ihluleka ngamanani aphezulu—umthengisi uvame ukunyamalala. Akukho siqinisekiso. Akukho okunye. Iphepha elibizayo nje.

Izibalo Zezindleko Zangempela

Cabanga ngezinombolo. Idivayisi eshibhile engu-$200 ingase ihlale amahora angu-500 ngaphambi kokuwohloka okukhulu. Emihlanganweni yemizuzu engu-15, lokho kungama-2,000 okwelashwa. Izindleko zokwelashwa ngakunye okusebenzayo? Cishe amasenti ayishumi.

Iphaneli yobungcweti engu-$800, ngokuphambene nalokho, yakhelwe ukuletha amahora angu-30,000 omkhiqizo ozinzile. Lokho kungukwelashwa okungu-120,000. Izindleko zokwelashwa ngakunye zehla zibe ngaphansi kwesenti elilodwa.

Kodwa lokhu kubalwa kucabanga ukuthi idivayisi eshibhile iletha noma yiluphi ukwelashwa okuphumelelayo nhlobo. Uma ubude bamaza bungalungile noma amandla enganele kusukela ngosuku lokuqala, izindleko zokwelashwa ngakunye okuphumelelayo ziba zingenamkhawulo. Awukhokheli lutho.

Izindleko Ezifihliwe Ongakwazi Ukuzibala

Isikhathi. Isonto ngalinye ukusebenzisa idivayisi engasebenzi kahle kuyisonto ongapholi. Ngobuhlungu obungapheli, izinkinga zesikhumba, noma ukululama ngemva kokuhlinzwa, lokho kubambezeleka kunezindleko zako. Isikhathi esilahlekile asikwazi ukubuyiselwa.

Ukukhungatheka. Ukungabaza okufika lapho ungaboni imiphumela—uzibuza ukuthi ingabe ukwelashwa ngokwako kukhulu kakhulu—lapho inkinga kwakuyithuluzi nje. Lokho kungabaza kuqeda ukwethemba ubuchwepheshe obusebenza ngempela.

Ukuthengwa Kwesibili. Iningi labathengi bamadivayisi ashibhile liba abafundi. Bachitha u-$200 befunda ukuthi u-$800 kwakuyintengo yangempela yento esebenzayo. Engeza ukuthenga kwesibili kokuqala, bese "isivumelwano" siba inketho ebiza kakhulu etholakalayo.

Umqondo Wokutshalwa Kwezimali

Idivayisi yokusetshenziswa kobuhle ekhaya ayiyona imali eningi. Iwukutshala imali empilweni yakho. Umbuzo awukhona ukuthi "kubiza malini?" kodwa "kubiza malini ukulibazisa imiphumela?"

Iphaneli engu-$800 enikeza inani lansuku zonke iminyaka eyishumi ibiza amasenti ngeseshini ngayinye. Ihlinzeka ngamaza okukhanya aqinisekisiwe kusukela ngosuku lokuqala. Igcina amandla azinzile kuyo yonke impilo yayo. Iza nezitifiketi zokuphepha ongazethemba. Inikeza ukwesekwa okusabelayo uma ukudinga.

Idivayisi engu-$200 ehluleka ngonyaka futhi iletha imiphumela engabazekayo phakathi nayo yonke? Yileyo izindleko zangempela.

Umugqa Ophansi

Amadivayisi ashibhile athembisa ukonga. Amaphaneli okwelapha ochwepheshe abomvu aletha inani. Awafani.

Thenga kanye. Thenga kahle. Yeka ukukhokhela isifundo kabili.
