Mumamiriro emazuva ano ehunyanzvi ari kufambira mberi nekukurumidza, mhinduro dzekuratidzira LED dzachinja zvakanyanya. Tekinoroji ye LED yakachinja indasitiri yemwenje, ichipa sarudzo dzinochengetedza simba uye dzinogara kwenguva refu kune vatengi nemabhizinesi zvakafanana. Pakati pemhando dzakasiyana dze LED, COB (Chip on Board) yakabuda sesarudzo yepamusoro nekuda kwehunhu hwayo hwehunyanzvi. Muchinyorwa chino, tichaongorora zvikonzero nei COB iine mukana pamusoro petekinoroji inoshandiswa zvakanyanya yeSMD (Surface Mount Device). Kubva pakuburitsa kwayo kupisa kwakaderera kusvika pakudzivirira kwakawedzerwa kubva kuzvinhu zvakatipoteredza, COB inonyatsopfuura vakwikwidzi vayo.
1.SMD vs. COB: Ndeipi Iri Nani?
Kana zvasvika kune tekinoroji yekuratidza LED, pane makwikwi maviri makuru ari pamusoro pemusika: SMD neCOB. Kunyange zvazvo Surface Mount Device yagara iri sarudzo huru yemhinduro dzemwenje dzeLED, COB yave iri imwe nzira yakanaka kwazvo.
Kusiyana neSMD, iyo ine ma LED diode akasungirirwa pabhodhi redunhu, COB ine ma LED chips akawanda mukati me module imwe chete. Iyi gadziriso yakasiyana haingowedzere kupenya uye simba remwenje chete asiwo inoderedza kudzikira kwechiedza padaro refu. Dhizaini yeCOB yemazuva ano inoita kuti chiedza chibude zvakanaka uye chifanane uye chine mavara akawanda.
II. Kupisa Kushoma Nekupisa Kushoma
Chimwe chezvakanakira zvikuru zveCOB kupfuura SMD kugona kwayo kutonga kupisa kwakanyanya. Tekinoroji yeCOB inopa kudzivirira kupisa kwakaderera nekuda kwekugadzirwa kwayo kwakapfava. Kudzivirira kupisa kunosarudza kuti kupisa kunopera sei kubva ku LED module, zvichiita kuti COB ishande zvakanaka pakuderedza kupisa. Izvi hazvigumiri pakuvandudza hupenyu hwenguva refu uye kuderedza zvinodiwa pakugadzirisa asiwo kuchengetedzwa kwakawedzerwa sezvoMamodule eCOBhadzinyanyi kuomeswa zvakanyanya.
III. Dziviriro Yakanakisisa Kubva Kuzvinhu Zvakatipoteredza
Kuratidzwa kweCOBinopa dziviriro yakanaka kubva kuzvinhu zvakasiyana-siyana zvakatipoteredza, ichivimbisa kugara kwenguva refu uye kuvimbika mumamiriro akasiyana-siyana. Yakagadziriswa ne epoxy resin kuti ivandudze mashandiro ekudzivirira. Inodzivirira zvakanyanya hunyoro, guruva, static, oxidation, uye chiedza chebhuruu. Dziviriro iyi yakawedzerwa inoita kuti mhinduro dzemwenje dzeCOB dzibudirire munzvimbo dzakaoma dzakadai senzvimbo dzekunze kana nzvimbo dzine hunyoro hwakawanda. Pamusoro pezvo, COB inodzivirira zvakanyanya oxidation inoita kuti ma LED arambe achipenya uye akarurama kwenguva yakareba, kusiyana neSMD.
IV. Hunhu hwakasviba uye hwakapinza.
Magadzirirwo etekinoroji yeCOB haangobatsiri chete pakugadzirisa kupisa kwayo uye kudzivirira asiwo anobatsira pakunaka kwemwenje wayo. Nekuda kwemachipisi e LED ari pedyo, COB inoburitsa chiedza chakanyatsojeka uye chakasimba, zvichikonzera mimvuri yakasviba uye zvinhu zvakapfava. Izvi zvinoita kuti COB ive yakakodzera kushandiswa uko kunyatsojeka uye kusiyana kwakanyanya kwakakosha, senge mamiziyamu, mashopu ekutengesa, uye magallery. Mwenje wakapinza unopihwa netekinoroji yeCOB unowedzera kutaridzika kwakanaka uye kujeka kwenzvimbo dzakavhenekerwa.
Sezvo indasitiri ye LED Display ichiramba ichichinja,Tekinoroji yeCOByave sarudzo itsva uye yepamusoro yemhinduro dze LED display. Hunhu hwayo hwehunyanzvi, hwakadai sekubuda kwechiedza chakafanana, kuburitsa kwemafuta mashoma, dziviriro yakawedzerwa kubva kuzvinhu zvakatipoteredza, uye chiedza chakajeka, zvinoita kuti ive sarudzo isingakundike. COB haingopi chete kushanda kwakanaka uye kugara kwenguva refu asiwo inopa kunaka kwekuona, izvo zvakakosha kune akasiyana mashandisirwo.
Nekuwedzera kwayo kukurumbira uye kufambira mberi mumabasa ekugadzira,Tekinoroji yeCOBiri kuwanikwa zviri nyore kune vatengi nemabhizinesi pasi rese. Kuratidzwa kweCOBMhinduro dzinovimbisa kupa sarudzo dzemwenje dzakajeka, dzinoshanda zviri nani, uye dzinogara kwenguva refu uku dzichichinja nzira yatinovhenekera nharaunda yedu.
