Mumazuva ano ari kukurumidza kufambira mberi tekinoroji mamiriro, ma LED ekuratidzira mhinduro akashanduka zvakanyanya. Tekinoroji yeLED yakashandura indasitiri yekuvhenekesa, ichipa simba-rinoshanda uye rinogara kwenguva refu sarudzo kune vatengi nemabhizinesi zvakafanana. Pakati peakasiyana magadzirirwo e LED, COB (Chip paBhodhi) yakabuda sechisarudzo chepamusoro nekuda kwehunyanzvi hwekuita. Muchikamu chino, tichaongorora zvikonzero nei COB inobata mukana pamusoro peiyo inoshandiswa zvakanyanya SMD (Surface Mount Device) tekinoroji. Kubva pakudzikira kwayo kwakadzikira kusvika pakuvandudza dziviriro kubva kune zvakatipoteredza, COB inokunda vakwikwidzi vayo zvechokwadi.
1.SMD vs. COB: Ndechipi Chiri Nani?
Kana zvasvika kune tekinoroji yekuratidzira ye LED, vaviri vanokwikwidza vanotonga pamusika: SMD uye COB. Nepo Surface Mount Chishandiso chave chiri chekuenda-kune sarudzo yemwenje ye LED mhinduro, COB yakabuda seimwe inotyisa imwe nzira.
Kusiyana neSMD, iyo inosanganisira ega akaiswa ma LED diode pabhodhi redunhu, COB inosanganisa akawanda machipisi e LED mukati memodule imwechete. Kumisikidzwa kwakasiyana uku hakungokwidziri kupenya uye kusimba kwemwenje chete asiwo kunoderedza kudzikira kwechiedza pamadaro marefu. COB's yekucheka-kumucheto dhizaini inoguma mune isina musono mwenje kubuda nekufanana uye yakakwirira ruvara kupa.
II. Low Thermal ine Kupisa Kushoma
Imwe yemabhenefiti ekutanga eCOB pamusoro peSMD kugona kwayo kwepamusoro kwekupisa kwekutonga. COB tekinoroji inopa yakaderera kupisa kwekudzivirira nekuda kweiyo yakawanda compact dhizaini. Iko kupisa kwekupisa kunotarisa kuti kupisa kunopera sei kubva ku LED module, zvichiita kuti COB inyatsoshanda mukuderedza kupisa kwekuvaka. Izvi zvinounza kwete chete kuvandudzwa kwehupenyu hurefu uye kuderedzwa kwekugadzirisa zvinodiwa asiwo kunowedzera kuchengetedzwa seCOB modulesvasinganyanyi kunyanyisa kupisa.
III. Kudzivirirwa Kwakanaka Kunopesana Nezvakatipoteredza Zvinhu
COB kuratidzainopa yakanakisa dziviriro kubva kune akasiyana siyana ezvakatipoteredza zvinhu, kuve nechokwadi kusimba uye kuvimbika mumamiriro akasiyana. Yakaporeswa ne epoxy resin kuvandudza mashandiro ekudzivirira. Inozvirumbidza nepamusoro pekudzivirira kunyorova, huruva, static, oxidation, uye mwenje webhuruu. Kudzivirirwa uku kunogonesa mhinduro dzemwenje dzeCOB kuti dzibudirire munzvimbo dzinonetsa dzakadai semaseti ekunze kana nzvimbo dzine hunyoro hwepamusoro. Pamusoro pezvo, kupikisa kweCOB kwepamusoro kune oxidation kunovimbisa kuti maLED anochengeta kupenya kwawo uye kurongeka kwemavara kwenguva yakareba, kusiyana nemamwe maSMD.
IV. Yakasviba uye Yakapinza mhando.
COB tekinoroji dhizaini haingokwidzi manejimendi ayo ekupisa nekudzivirira asi zvakare inobatsira pakuvheneka kwayo kunaka. Nekuda kweiyo yakanyatso paradzana machipisi e LED, COB inoburitsa yakanyatso kutarisisa uye yakanyanya mwenje wechiedza, zvichikonzera mimvuri yakasviba uye crisper ruzivo. Izvi zvinoita kuti COB inyanyokodzera zvikumbiro uko kurongeka uye kusiyanisa kwakanyanya kwakakosha, senge mamuseum, zvitoro zvinoratidzwa, uye magaraji. Iyo mwenje wakapinza wakapihwa neCOB tekinoroji inowedzera kukwezva kwekuona uye kujeka kwenzvimbo dzakavhenekerwa.
Sezvo iyo LED Display indasitiri inoenderera mberi nekushanduka,COB tekinorojiyakabuda sechitsva uye chepamusoro sarudzo ye LED kuratidza mhinduro. Hunhu hwayo hwehunyanzvi, hwakadai sekubuda kwechiedza chakafanana, kuburitsa kwakadzikira, kukwidziridzwa kunopesana nemamiriro ekunze, uye kupenya kwakapinza, inoita kuti ive sarudzo isingarondwe. COB haingopi chete kuvandudzwa kwekuita uye hupenyu hurefu asiwo inopa zvirinani zvemhando yekuona, izvo zvakakosha kune akasiyana maapplication.
Nekuzivikanwa kwayo kuri kuwedzera uye kufambira mberi mukugadzira maitiro,COB tekinorojiiri kuwanikwa nyore nyore kune vatengi nemabhizinesi pasi rese. Kumbundikira COB kuratidzamhinduro dzinovimbisa kuunza zvinopenya, zvinonyatsoshanda, uye zvekugara-refu sarudzo dzemwenje tichishandura nzira yatinovhenekera nharaunda yedu.
