Ma'anar COB encapsulation
Ana kiran COB Chips on Board (COB), wanda shine fasaha don magance matsalar rashin zafi na LED. Idan aka kwatanta da fasahar in-line da SMD, yana da fasali da yawa na ceton sararin samaniya, sauƙaƙe marufi, da ingantaccen sarrafa zafi.
Rufin COB, wato, guntu A kan jirgi, shine a liƙa guntu mara amfani zuwa madaidaicin haɗin haɗin gwiwa tare da manne mai ɗaure ko mara amfani, sannan a yi haɗin haɗin waya don gane haɗin lantarki. Idan guntuwar guntu ta fito kai tsaye zuwa iska, yana iya kamuwa da gurɓatawa ko lahani da mutum ya yi, yana shafar ko lalata aikin guntu, don haka guntu da igiyar haɗin gwiwa suna lulluɓe da manne. Ana kuma kiran wannan fakitin a matsayin abin rufe fuska mai laushi.
Amfanin marufi na COB
1. Ultra-bakin ciki: Dangane da ainihin bukatun abokan ciniki, ana iya amfani da hukumar PCB tare da kauri daga 0.4-1.2mm don rage nauyin zuwa 1/3 na samfuran gargajiya na asali, wanda zai iya rage girman tsarin, sufuri da injiniya. halin kaka ga abokan ciniki.
2. Anti- karo da matsawa: The COB samfurin kai tsaye encapsulates LED guntu a concave fitila matsayi na PCB hukumar, sa'an nan kuma aka warke ta epoxy guduro. Fuskar fitilar fitilar tana jujjuyawa zuwa wani fili mai siffa, wanda yake da santsi da wuya, kuma yana da juriya ga karo da lalacewa.
3. Babban kusurwar kallo: Kunshin COB yana amfani da haske mai zurfi mara kyau, kusurwar kallo ya fi digiri 175, kusa da digiri 180, kuma yana da mafi kyawun tasirin launi mai laushi.
4. Bendable: Ƙarfin lankwasa wani abu ne na musamman na taron COB. Lankwasawa PCB baya haifar da lalacewa ga kwakwalwan LED da aka lullube. Sabili da haka, ana iya ƙirƙira allon baka na LED, allon madauwari, da allon wavy ta amfani da samfuran COB. Yana da manufa mai mahimmanci don keɓaɓɓen fuska a mashaya da wuraren shakatawa na dare. Ana iya raba shi ba tare da ɓata lokaci ba, tsarin samarwa yana da sauƙi, kuma farashin yana da ƙasa da ƙasa da allon siffa na LED wanda keɓaɓɓen allon kewayawa da tsarin nuni na gargajiya.
5. Ƙarfin zafi mai ƙarfi: Ana tattara samfuran COB akan allon PCB, kuma ana watsa zafin wick cikin sauri ta cikin foil ɗin jan karfe akan allon PCB. Kaurin foil ɗin tagulla na hukumar PCB yana da ƙayyadaddun buƙatun fasaha, kuma saboda tsarin zinare na nutsewa, da wuya yana haifar da ƙarancin haske. Saboda haka, akwai ƙananan lalacewar LED kuma samfuran COB suna haɓaka rayuwa sosai.
6, mai jure lalacewa, mai sauƙin tsaftacewa: saman ma'aunin fitilar yana jujjuya shi cikin wani yanayi mai faɗi, santsi da ƙarfi, juriya da lalacewa; Idan akwai matattu aibobi, za ku iya gyara maki ta aya; babu abin rufe fuska, ana iya tsabtace ƙura da ruwa ko zane.
7, Excellent duk-weather halaye: shi sau uku kariya magani, hana ruwa, danshi hujja, lalata juriya, ƙura rigakafin, anti-a tsaye gama, anti-oxidation, UV juriya sakamako ne fice. Don haka yana iya saduwa da duk yanayin aiki na yanayi, ana iya amfani da bambancin zafin jiki daga digiri 30 zuwa sifili 80 a kullum.
