Parizvino, huwandu hwemhando yemwenje yemwenje ye LED pamusika haina kuenzana.Munzvimbo dzakawanda, marambi emumugwagwa e LED haaonekwe zvakajeka munguva pfupi.Mushure mekutsvagisa kweVagadziri vemagetsi emumugwagwa, chikonzero chechiitiko ichi ndechekuti mwenje wemugwagwa we LED une hurombo hwekupisa kupisa kuita.Kana kupisa kwekupisa kuita kwakashata, tembiricha yemukati yemwenje ye LED ichave yakanyanya kukwirira.Kana tembiricha ye LED ichikwira, kushongedzwa kwayo kwejunction kunoderera, zvichikonzera kudzikira kwekutendeuka-on voltage.
Pasi pemamiriro akafanana emagetsi, kupisa kwemukati kukwira kwechiedza che LED kuchawedzera iyo LED ikozvino.Kuwedzera kwezvino kunoita kuti tembiricha iwedzere kuwedzera, izvo zvinokonzeresa kutenderera kwakashata kupisa LED chip.Uyezve, kutonhora kwemukati kwechiedza chemugwagwa che LED chakanyanyisa, izvo zvinokonzerawo kuora kwechiedza che LED chip kuti chiwedzere, kuitira kuti itungamirire kune chinhu chakajeka uye chisina kujeka munguva yemberi iri pedyo.Saka chii chikonzero chekushaya kupisa kwekupisa kwekuita kwechiedza chemugwagwa che LED?
Kutanga, kunaka kwe LED mwenje mwenje ivo pachavo.
Iyo LED chip inoshandiswa ine yakashata yekupisa conductivity, uye tembiricha ye LED inofa haifambiswe kumusoro (yemukati kupisa uye kutonhora).Kunyange kana kunyura kwekushisa kuchiwedzerwa, kupisa kwemukati hakugoni kupera zvachose, uye ipapo chiedza chemugwagwa che LED hachina kupisa mukati.
Chechipiri, kukwira kwekushisa kunokonzerwa ne LED street light power supply.
LED yemugwagwa chiedza chemagetsi emhando haina kunaka.Kana iyo LED yakabatidzwa, iyo isiri-mutsara yemagetsi uye kushanduka kusina simba kwemagetsi kuchaita kuti ikozvino kuburikidza ne LED chip iwedzere, izvo zvichaita kuti kupisa kwemukati kuve kwakanyanya, izvo zvinokanganisa kupisa. disipation performance ye LED street light.
Wese munhu anofanirwa kutarisisa kune hupenyu hurefu hwemwenje yemugwagwa we LED.Paunenge uchitenga, edza kusarudza vagadziri vemagetsi emumugwagwa e LED vanovimbika, uye zvakare teerera kune nguva dzose kugadzirisa, kuitira kuti uve nechokwadi chekugadzikana kwemwenje ye LED mumugwagwa.
