Chii chinonzi LEDs uye inoshanda sei?
LED inomirira light emitting diode.Zvigadzirwa zvemwenje zve LED zvinoburitsa mwenje inosvika makumi mapfumbamwe muzana zvakanyanya kupfuura incandescent bulbs.Vanoshanda sei?Mhepo yemagetsi inopfuura nepamicrochip, iyo inovhenekera zvitubu zvidiki zvatinodaidza kuti maLED uye mhedzisiro yacho chiedza chinooneka.Kuti udzivise nyaya dzekuita, kupisa kwe LED kunogadzira kunonyudzwa mukati mekupisa singi.
Hupenyu hwose hwe LED Mwenje Zvigadzirwa
Upenyu hunobatsira hwezvigadzirwa zvemwenje zve LED zvinotsanangurwa zvakasiyana pane zvezvimwe zvitubu zvechiedza, zvakadai se incandescent kana compact fluorescent lighting (CFL).Ma LED haawanzo "kupisa" kana kutadza.Pane kudaro, vanoona 'lumen depreciation', umo kupenya kwe LED kunodzima zvishoma nezvishoma nekufamba kwenguva.Kusiyana nema bulbs e-incandescent, LED "hupenyu hwose" inotangwa pakufungidzira apo chiedza chinobuda chinoderera ne30 muzana.
Ma LED Anoshandiswa Sei Mukuvheneka
Ma LED anosanganisirwa muma bulbs uye zvigadziriso zvezvizhinji zvekuvhenekesa zvikumbiro.Diki muhukuru, maLED anopa akasiyana ekugadzira mikana.Mamwe magirobhu emwenje e LED anogona kunge akafanana neanozivikanwa magirobhu uye zvirinani aenderane nekuonekwa kwechinyakare magirobhu.Zvimwe zvigadziriso zvemwenje zve LED zvinogona kunge zvine ma LED akavakirwa mukati sechinhu chisingaperi mwenje sosi.Kune zvakare nzira dzakasanganiswa apo isiri-yechinyakare "girobhu" kana inotsiviwa mwenje sosi fomati inoshandiswa uye yakanyatsogadzirirwa gadziriso yakasarudzika.Ma LED anopa mukana wakakura wekuvandudza mukuvhenekesa fomu zvinhu uye inokodzera hupamhi hwemashandisirwo kupfuura echinyakare mwenje matekinoroji.
LEDs uye Kupisa
Ma LED anoshandisa masinki ekupisa kuti atore kupisa kunogadzirwa ne LED uye kuibvisa munzvimbo yakapoteredza.Izvi zvinoita kuti ma LED arege kupisa uye kupisa kunze.Thermal manejimendi ndiyo inonyanya kukosha mukuita kwakabudirira kwe LED mukati mehupenyu hwayo.Iyo yakakwirira tembiricha iyo ma LED anoshandiswa, iyo inokurumidza kukurumidza mwenje inoshatisa, uye hupfupi hupenyu hunobatsira huchava.
Zvigadzirwa zve LED zvinoshandisa zvakasiyana-siyana zvakasiyana-siyana zvekupisa sink magadzirirwo uye masisitimu ekugadzirisa kupisa.Nhasi, kufambira mberi kwezvinhu zvakabvumira vagadziri kugadzira ma bulbs e LED anofanana nemhando uye hukuru hwechinyakare incandescent bulbs.Pasinei nekugadzirwa kwekupisa kwekupisa, zvigadzirwa zvose zve LED zvakawana ENERGY STAR zvakaedzwa kuti zvive nechokwadi kuti zvinogadzirisa kupisa kuitira kuti chiedza chinobuda chichengetedzwe zvakanaka kuburikidza nekuguma kwehupenyu hwayo hwakarongwa.
