Nanga bwanji COB Light Source

Koposa - woonda dongosolo: 2835 makulidwe ndi 0,8mm, amene angathe kuthetsa vuto la kuwala mawanga amene alipo 3528; okonza otsatirawa kuti afufuze ubwino wa gwero la kuwala kwa COB: ntchito yabwino kwambiri: gwiritsani ntchito teknoloji ya COB, kumanga chip nude DIE mwachindunji pa bolodi la PCB Pamwambapa, zofunikira zogwirizanitsa fungulo lotsogolera kwa mtsogoleri zinathetsedwa, ndipo kugwirizana kachulukidwe ka zolowetsa/zotulutsa (I/O) zidawonjezedwa. Zogulitsazo zinali zodalirika komanso zokhazikika. Kuphatikizana kwapamwamba: gwiritsani ntchito ukadaulo wa COB kuti muchepetse kulumikizana pakati pa chip ndi bolodi loyang'anira ntchito, ndikuwongolera kuphatikiza kwazinthuzo. Magwero a kuwala kwa COB Pamalo akulu owala (malo owoneka bwino): kuchuluka kwa kuwala: kufika 90%. Mtengo: Komabe 20W monga chitsanzo: Ngati mungasankhe kugwiritsa ntchito 2835 ndi 0.12W 14-16LM, ndiye kuti nyali za fulorosenti za 20W zimafuna mikanda ya 144. Ukadaulo uwu ndi woyenera kwambiri kugwiritsa ntchito magawo a ceramic osagwirizana ndi kutentha kwambiri okhala ndi utsogoleri wapamwamba (osavuta kusungunula tokhala ndi totupa). Komabe, pakugwiritsa ntchito kwa SMT pa board organic circuit, malo owotcherera kwambiri pa IC amafunikanso kugwiritsa ntchito zitsulo zosungunuka kuti zigwirizane. Gwero lounikira la COB ndilosavuta kusonkhana, ndipo gawo lake limatha kukhazikitsidwa mwachindunji pa radiator ya nyali. Popeza gwero la kuwala kwa COB lotembenuzidwa ndi la insulator, izi zithandizira zowunikira za LED kudutsa mayeso osiyanasiyana amagetsi apamwamba. Gwero la kuwala kwa COB lotembenuzidwa ndilofunika kwambiri pamsika wapano. Imagawidwa m'mitundu yophukira ndi COB yovomerezeka. Zotsatirazi za Tianhui Optoelectronics Technology kupanga luso lotsika mtengo lopangira ukadaulo wopangira aliyense, monga electroplating kapena template kusindikiza (ndi sputtering kapena plating plating mankhwala “Chida cholekanitsa gwero la kuwala kwa LED →GuluGerman wowona ml →Nyali LED ”Makamaka chifukwa palibe okonzeka - anapanga pachimake kuwala chigawo chimodzi, amene si nthawi yambiri, komanso mkulu. COB kuwala kochokera pamwamba, kuphimba mphamvu kwa 5-50W, kumagwirizana bwino. Kuchita kwakukulu: Ultra -highlight amphamvu, kutulutsa kwamtundu wapamwamba, kuwunikira kwakukulu, ntchito yamtundu wowala makonda. Kuyang'ana kwakukulu: Chitsime chosazama chowala chozungulira chimagwiritsidwa ntchito. Mawonekedwe ake ndi aakulu kuposa madigiri a 175, pafupi ndi madigiri a 180, ndipo ali ndi mtundu wowoneka bwino wobalalika. Kuthekera kwamphamvu kwa kutentha kwamphamvu: ikani gwero la kuwala kwa COB pamanja, mutha kufalitsa kutentha mwachangu kudzera mu superconducting aluminium, COB ma CD. “Kuwona za miya →Nyali LED ”, Mutha kuyikamo tchipisi tambiri pa MCPCB pa bolodi yosindikizira yachitsulo, ndikuchotsa kutentha kudzera pagawo lapansi kuti mupulumutse mtengo wonyamula wa LED.
