Tanthauzo la COB encapsulation
COB imatchedwa Chips on Board (COB), yomwe ndi teknoloji yothetsera vuto la kutentha kwa LED. Poyerekeza ndi ukadaulo wapaintaneti ndi SMD, ili ndi zinthu zingapo zakupulumutsa malo, kuyika kosavuta, komanso kuwongolera bwino kwamafuta.
The COB encapsulation, ndiye kuti, chip Pa bolodi, ndi kumamatira chopanda kanthu ku cholumikizira gawo lapansi ndi guluu conductive kapena non-conductive, ndiyeno kupanga mawaya chomangira kuzindikira kulumikiza magetsi. Ngati chip chopanda kanthu chikuwonekera mwachindunji mlengalenga, chikhoza kuipitsidwa kapena kuwonongeka kopangidwa ndi anthu, kumakhudza kapena kuwononga ntchito ya chip, kotero kuti chip ndi waya womangirira amatsekedwa ndi guluu. Phukusili limatchedwanso encapsulation yofewa.
Ubwino wa COB phukusi
1. Ultra-woonda: Malinga ndi zosowa zenizeni za makasitomala, bolodi la PCB ndi makulidwe kuchokera ku 0.4-1.2mm angagwiritsidwe ntchito kuchepetsa kulemera kwa 1/3 ya zinthu zoyambirira zachikhalidwe, zomwe zingathe kuchepetsa kwambiri zomangamanga, zoyendetsa ndi zomangamanga. ndalama kwa makasitomala.
2. Anti-kugunda ndi kukanikiza: The COB mankhwala mwachindunji encapsulates LED Chip mu concave nyale malo a bolodi PCB, ndiyeno kuchiritsidwa ndi epoxy utomoni. Pamwamba pa nsonga ya nyaliyo ndi yopindika kukhala yozungulira, yomwe imakhala yosalala komanso yolimba, ndipo imagonjetsedwa ndi kugundana ndi kuvala.
3. Ngodya yayikulu yowonera: Phukusi la COB limagwiritsa ntchito kuwala kozungulira bwino, kowonerako ndi kokulirapo kuposa madigiri 175, pafupi ndi madigiri 180, ndipo imakhala ndi mawonekedwe owoneka bwino amtundu wa dimming.
4. Kupindika: Mphamvu yopindika ndi gawo lapadera la msonkhano wa COB. Kupindika kwa PCB sikuwononga tchipisi ta LED. Chifukwa chake, zowonera za LED za arc, zowonera zozungulira, ndi zowonera za wavy zitha kupangidwa mosavuta pogwiritsa ntchito ma module a COB. Ndi gawo loyenera lazowonera zamunthu m'mabala ndi makalabu ausiku. Zitha kukhala zopanda malire, kapangidwe kake kamakhala kosavuta, ndipo mtengo wake ndi wotsika kwambiri kuposa mawonekedwe a LED omwe amapangidwa ndi bolodi losinthika komanso gawo lowonetsera zachikhalidwe.
5. Kutentha kwamphamvu kwamphamvu: Zinthu za COB zimayikidwa pa bolodi la PCB, ndipo kutentha kwa chingwe kumafalikira mofulumira kudzera muzojambula zamkuwa pa bolodi la PCB. Makulidwe a zojambulazo zamkuwa za bolodi la PCB zimakhala ndi zofunikira zaukadaulo, ndipo chifukwa cha kumiza golide, sizimayambitsa kuchepetsedwa kwa kuwala. Chifukwa chake, pali zowonongeka zochepa za LED ndipo zinthu za COB zimakulitsa moyo.
6, osavala, osavuta kuyeretsa: pamwamba pa nyaliyo ndi otambasuka kukhala ozungulira, osalala komanso olimba, osagundana komanso osamva kuvala; Ngati pali malo akufa, mukhoza kukonza mfundo ndi mfundo; palibe chigoba, fumbi likhoza kutsukidwa ndi madzi kapena nsalu.
7, Makhalidwe abwino kwambiri a nyengo yonse: chithandizo chachitetezo katatu, chopanda madzi, chinyontho, kukana dzimbiri, kupewa fumbi, kutha kwa anti-static, anti-oxidation, kukana kwa UV ndizapadera. Chifukwa chake imatha kukumana ndi nyengo zonse zogwirira ntchito, kusiyana kwa kutentha kwa madigiri 30 mpaka ziro 80 kumatha kugwiritsidwabe ntchito nthawi zonse.
