Mwenje ye LED madhiodhi emwenje-emitting, ayo anoshandisa yakasimba semiconductor machipisi sezvinhu zvinopenya.Kuenzaniswa nemarambi echinyakare, marambi eLED anochengetedza simba, ane hushamwari kwezvakatipoteredza, uye ane mavara akanaka ekupa uye kumhanya kwekupindura.
(1) Kuchengetedza magetsi ndicho chinhu chinonyanya kuzivikanwa chemwenje ye LED
Maererano nekushandiswa kwesimba, kushandiswa kwesimba kwemarambi e LED chikamu chegumi chemarambi e-incandescent uye chikamu chechina chemarambi ekuchengetedza simba.Ichi ndicho chimwe chezvinhu zvikuru zvemwenje we LED.Vanhu mazuvano vanotsigira kuchengetedza kwesimba uye kuchengetedza kwezvakatipoteredza.Izvo chaizvo nekuda kweichi chimiro chekuchengetedza simba kuti mashandisirwo emhando yemwenje ye LED yakakura kwazvo, zvichiita kuti mwenje we LED uzivikanwe zvakanyanya.
(Vaviri) vanogona kushanda mune yakakwirira-kumhanya switching state
Kana isu kazhinji tichifamba munzira, tinozoona kuti yega yega skrini ye LED kana mufananidzo hautarisike.Izvi zvinoratidza kuti mwenje we LED unogona kubatidzwa nekudzima nekumhanya kukuru.Zvisinei, nokuda kwemarambi e-incandescent atinowanzo shandisa, haigoni kuwana mamiriro ekushanda akadaro.Muhupenyu hwemazuva ose, kana shanduko yakashandurwa kakawanda, inokonzera zvakananga filament yemwenje we incandescent.Ichi zvakare chikonzero chakakosha chekuzivikanwa kwemwenje ye LED.
(3) Kuchengetedzwa kwezvakatipoteredza
Mwenje we LED hauna chero zvinhu zvinorema zvesimbi senge mercury, asi mwenje we incandescent unawo, unoratidza maitiro ekudzivirira kwezvakatipoteredza emwenje we LED.Mazuva ano, vanhu vanokoshesa kuchengetedzwa kwezvakatipoteredza, saka vanhu vakawanda vanoda kusarudza mwenje we LED.
(4) Kukurumidza kupindura
Chimwe chinhu chakatanhamara chemwenje we LED ndechekuti kumhanya kwekupindura kuri kukurumidza.Chero bedzi simba rakabatidzwa, mwenje we LED unovheneka ipapo ipapo.Kuenzaniswa nemarambi ekuchengetedza simba atinowanzo shandisa, kukurumidza kwekupindura kunokurumidza.Kana girobhu rechinyakare rabatidzwa, rinowanzotora nguva yakareba kuti rivheneke mukamuri, uye rinongokwanisa kuvheneka mushure mekunge girobhu rapisa zvachose.(5) Kuenzaniswa nemamwe magetsi emwenje, mwenje dze LED dzakanyanya "kuchena"
Iyo inonzi "yakachena" hairevi kuchena kwepamusoro uye mukati memwenje, asi mwenje unotonhora sosi, hauburitse kupisa kwakanyanya, uye haukweve zvipembenene izvo sechiedza nekupisa.Kunyanya muzhizha, pachava netsikidzi dzakawanda mumaruwa.
Zvimwe zvipembenene zvinoda kupisa nemasikirwo.Mwenje weIncandescent uye marambi ekuchengetedza simba achaunza kupisa mushure menguva yekushandiswa.Kupisa uku kunoitika kufarirwa netumbuyu, uye zviri nyore kukwezva zvipembenene.Izvi pasina mubvunzo zvichaunza zvakawanda zvakasvibiswa pamusoro pemwenje, uye tsvina yezvipembenene ichaita kuti imba yacho ive yakasviba zvikuru.Nekudaro, mwenje we LED inotonhora sosi uye haikweve zvipembenene.Nenzira iyi, tsvina yezvipembenene haizogadzirwa.Nokudaro, mwenje we LED unowedzera "kuchena".
