Nekufambira mberi nekusimudzira nzanga, simba uye nyaya dzezvakatipoteredza zvave kuwedzera kuve chinangwa chenyika. Kuchengetedzwa kwesimba uye kuchengetedza kwezvakatipoteredza zvawedzera kuve simba rekufambisa rekufambira mberi kwevanhu. Muhupenyu hwevanhu zuva nezuva, kudiwa kwesimba rekuvhenekesa kunotora chikamu chakakura kwazvo chekushandiswa kwesimba rose, asi nzira dziripo dzekuvhenekesa dzechinyakare dzine hurema hwakadai sekushandiswa kukuru kwemagetsi, hupenyu hupfupi hwebasa, kushomeka kwekushandura uye kusvibiswa kwezvakatipoteredza, izvo zvisiri izvo. zvinoenderana nechinangwa chekuchengetedza simba uye kuchengetedza zvakatipoteredza munharaunda yemazuva ano, Naizvozvo, nzira itsva yekuvhenekesa inosangana nezvinodiwa zvekusimudzirwa kwevanhu inodiwa kutsiva mararamiro emagetsi echinyakare.

Kuburikidza nekuedza kunoramba kuripo kwevatsvaguri, girini yekuvhenekesa modhi ine hupenyu hurefu hwesevhisi, yakanyanya kutendeuka kushanda zvakanaka uye kushomeka kwemamiriro ekunze, kureva semiconductor chena mwenje emitting diode (WLED), zvakagadzirirwa. Kana ichienzaniswa neyechinyakare yekuvhenekesa modhi, WLED ine mabhenefiti ekushanda kwepamusoro, hapana kusvibiswa kwemekiyuri, kuderera kwekabhoni, hupenyu hurefu hwebasa, vhoriyamu shoma uye kuchengetedza simba, Izvi zvinoita kuti ishandiswe zvakanyanya mukufambisa, kuratidzwa kwemwenje, michina yekurapa uye zvigadzirwa zvemagetsi.

Panguva imwe,LEDrave richizivikanwa sechinhu chitsva chechiedza chinonyanya kukosha muzana remakore rechi21. Pasi pemamiriro akafanana ekuvhenekesa, simba rekushandisa reWLED rakaenzana ne50% yemarambi efluorescent uye 20% yemwenje weincandescent. Parizvino, mashandisirwo emagetsi echinyakare epasi rose anotora chikamu che13% chesimba rinoshandiswa pasirese. Kana WLED ikashandiswa kutsiva mwenje wepasirese wepasirese, kushandiswa kwesimba kunoderedzwa nehafu, nekushamisa kwekuchengetedza simba uye chinangwa chehupfumi.

Parizvino, white light emitting diode (WLED), inozivikanwa seyechina yechizvarwa chekuvhenekesa mudziyo, yakwezva vanhu vazhinji nekuda kwekuita kwayo kwakanaka. Vanhu vakasimbisa zvishoma nezvishoma tsvagiridzo pachena LED, uye midziyo yayo inoshandiswa zvakanyanya muminda yakawanda senge kuratidza uye mwenje.

Muna 1993, tekinoroji yeGan yeblue light emitting diode (LED) yakaita budiriro kekutanga, iyo yakasimudzira kuvandudzwa kweLED. Pakutanga, vaongorori vakashandisa Gan sechiedza chebhuruu sosi uye vakaona kuchena kwechiedza cheimwe inotungamirwa nekushandisa phosphor shanduko nzira, iyo yakamhanyisa kumhanya kwe LED ichipinda munzvimbo yekuvhenekesa.

Iko kushandiswa kukuru kweWLED kuri mumunda wekuvhenekesa kwemba, asi maererano nemamiriro ekutsvaga aripo, WLED ichine matambudziko makuru. Kuti tiite kuti WLED ipinde muhupenyu hwedu nekukurumidza sezvinobvira, isu tinofanirwa kugara tichinatsiridza nekuvandudza kwayo kupenya kwayo, kuburitsa kwemavara uye hupenyu hwesevhisi. Kunyange zvazvo ikozvino LED chiedza sosi haigoni kutsiva zvachose chiedza chekare chinoshandiswa nevanhu, nekuvandudzwa kwesainzi uye tekinoroji, marambi e LED anozowedzera kufarirwa.
