Chii chinonzi LEDs uye inoshanda sei?
LEDinomiriralight emitting diode.Zvigadzirwa zvemwenje zve LED zvinoburitsa mwenje inosvika 90% zvakanyanya kupfuura incandescent bulbs.Vanoshanda sei?Mhepo yemagetsi inopfuura nepamicrochip, iyo inovhenekera zvitubu zvidiki zvatinodaidza kuti maLED uye mhedzisiro yacho inooneka chiedza.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 kukundikana.Pane kudaro, vanowana 'lumen depreciation', umo kupenya kwe LED kunodzima zvishoma nezvishoma nekufamba kwenguva.Kusiyana nema bulbs e-incandescent, LED "hupenyu hwehupenyu" hunotangwa pakufungidzira apo chiedza chinobuda chinoderera ne30 muzana.
Ma LED Anoshandiswa Sei Mukuvheneka?
Ma LED anosanganisirwa muma bulbs uye zvigadziriso zvezvishandiso zvemwenje zvakajairika.Diki muhukuru, maLED anopa akasiyana ekugadzira mikana.Mamwe magirobhu emwenje e LED anogona kunge akafanana neanozivikanwa magirobhu uye zvirinani kuenderana nekutaridzika 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 yakanyatso gadzirirwa chimiro chakasiyana.Ma LED anopa mukana wakakura wekuvandudza mukuvhenekesa fomu zvinhu uye inokodzera hupamhi hwemashandisirwo kupfuura echinyakare mwenje matekinoroji.
LEDs uye Kupisa
Ma LED anoshandisa kupisa kunyura 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 nemaumbirwo uye saizi dzechinyakare incandescent bulbs.Pasinei nekugadzirwa kwekupisa kwekupisa, zvigadzirwa zve LED zvakawana ENERGY STAR zvakaedzwa kuti zvive nechokwadi kuti zvinogadzirisa kupisa kuitira kuti chiedza chinobuda chichengetedzwe zvakanaka kuburikidza nekuguma kwehupenyu hwayo hwakayerwa.
Mwenje we LED wakasiyana sei pane mamwe magetsi, senge incandescent uye Compact Fluorescent (CFL)?
Mwenje we LED unosiyana kubva kune incandescent uye fluorescent munzira dzakawanda.Kana yakagadzirwa zvakanaka, mwenje we LED unoshanda zvakanyanya, unochinja-chinja, uye unogara kwenguva refu.
Ma LED ndiwo "directional" light sources, zvinoreva kuti anobudisa chiedza mune imwe nzira, kusiyana ne incandescent neCFL, iyo inobudisa chiedza nekupisa kumativi ose.Izvi zvinoreva kuti ma LED anokwanisa kushandisa chiedza uye simba zvakanyanya muhuwandu hwekushanda.Nekudaro, zvinoreva zvakare kuti huinjiniya hwakaoma hunodiwa kugadzira mwenje we LED unopenya mwenje munzira dzese.
Akajairika ma LED mavara anosanganisira amber, tsvuku, girini, uye bhuruu.Kuti ibudise chiedza chichena, ma LED akasiyana-siyana anosanganiswa kana kuvharwa ne phosphor zvinhu zvinoshandura ruvara rwechiedza kune rinozivikanwa "chena" chiedza chinoshandiswa mudzimba.Phosphor chinhu chine yellowish chinovhara mamwe ma LED.Ma LED ane mavara anoshandiswa zvakanyanya semarambi echiratidzo uye mwenje wechiratidzo, sebhatani remagetsi pakombuta.
MuCFL, magetsi anoyerera pakati pema electrode pamagumo echubhu ine magasi.Izvi zvinogadzira ultraviolet (UV) chiedza uye kupisa.Iyo UV mwenje inoshandurwa kuita mwenje unooneka painorova phosphor coating mukati me bulb.
