Menene COB LED allon?

COB (Chip on Board) fasahar marufi ce ta LED wacce ta bambanta da fasahar nunin LED ta gargajiya. Fasahar COB tana shigar da kwakwalwan kwamfuta masu yawa na LED kai tsaye a kan allon kewayawa, yana kawar da buƙatar marufi daban. Wannan fasaha yana ƙara haske kuma yana rage zafi, yana sa nuni ya zama marar lahani.

Abũbuwan amfãni idan aka kwatanta da na gargajiya LED fuska

COB LED fuska suna da fa'ida a bayyane akan allon LED na gargajiya dangane da aiki. Ba shi da rata tsakanin kwakwalwan LED, yana tabbatar da haske iri ɗaya da guje wa matsaloli kamar "tasirin ƙofar allo". Bugu da ƙari, allon COB yana ba da ƙarin ingantattun launuka da bambanci mafi girma.

Fa'idodin COB LED allon

Saboda ƙaramin girman kwakwalwan LED, ƙimar fasahar marufi na COB ya karu sosai. Idan aka kwatanta da na'urori masu hawan dutse (SMD), tsarin COB ya fi dacewa, yana tabbatar da daidaiton nuni, yana riƙe da ƙarfi mai ƙarfi koda lokacin da aka duba shi a kusa, kuma yana da kyakkyawan aikin watsar da zafi, don haka inganta kwanciyar hankali da aminci. COB kunshin kwakwalwan kwamfuta da fil suna haɓaka ƙunsar iska da juriya ga rundunonin waje, suna samar da fuskar da ba ta da kyau. Bugu da ƙari, COB yana da mafi girman tabbacin danshi, anti-static, lalacewa-proof da ƙura-hujja Properties, da kuma surface kariya matakin iya isa IP65.

Dangane da tsari na fasaha, fasahar SMD tana buƙatar reflow soldering. Lokacin da solder manna zafin jiki ya kai 240 ° C, da epoxy guduro asarar kudi iya isa 80%, wanda zai iya sauƙi sa manne ya rabu da LED kofin. Fasahar COB ba ta buƙatar tsarin sake kwarara don haka ya fi kwanciyar hankali.

Duban Kusa: Daidaitaccen Pitch Pitch

Fasahar COB LED tana haɓaka ƙimar pixel. Karamin farar pixel yana nufin mafi girman girman pixel, don haka samun ƙuduri mafi girma. Masu kallo na iya ganin cikakkun hotuna ko da suna kusa da mai duba.

Haskaka Duhun: Ingantaccen Haske

Fasahar COB LED tana da alaƙa da ingantaccen watsawar zafi da ƙarancin ƙarancin haske. Ana manne guntuwar COB kai tsaye akan PCB, wanda ke faɗaɗa wurin zubar da zafi kuma ƙarancin haske ya fi na SMD kyau. Rarraba zafi na SMD ya dogara ne akan angon da ke ƙasa.

Fadada Horizons: Hankali

COB ƙananan fasaha yana kawo kusurwar kallo mai faɗi da haske mafi girma, kuma ya dace da wurare daban-daban na ciki da waje.

Tauri Mai Tauri

Fasahar COB tana da tasiri mai jurewa kuma ba ta shafar mai, danshi, ruwa, ƙura da oxidation.

Babban Kwatance

Bambanci shine muhimmiyar alamar nunin nunin LED. COB yana ɗaga bambanci zuwa sabon matakin, tare da madaidaicin rabo na 15,000 zuwa 20,000 da madaidaicin juzu'i na 100,000.

Koren Zamani: Amfanin Makamashi

Dangane da ingantaccen makamashi, fasahar COB tana gaba da SMD kuma shine babban mahimmanci don rage farashin aiki yayin amfani da manyan fuska na dogon lokaci.

Zaɓi Cailiang COB LED fuska: zaɓi mai wayo

A matsayin mai ba da nuni na aji na farko, Cailiang Mini COB LED allon yana da fa'idodi uku masu mahimmanci:

Fasahar Yanke-Baki:Ana amfani da fasahar marufi COB cikakken juzu'i-chip don haɓaka aiki da samar da ƙaramar nunin LED-pitch.

Kyakkyawan Ayyuka:Nunin Cailiang Mini COB LED yana da fa'idodi na babu haske crosstalk, bayyanannun hotuna, launuka masu haske, ingantaccen yanayin zafi, tsawon rayuwar sabis, babban bambanci, gamut launi mai faɗi, babban haske, da saurin wartsakewa.

Mai tsada:Cailiang Mini COB LED fuska suna ceton makamashi, mai sauƙin shigarwa, yana buƙatar ƙaramar kulawa, suna da ƙarancin haɗin gwiwa kuma suna ba da kyakkyawan ƙimar farashi / aiki.

Daidaiton Pixel:Cailiang yana ba da zaɓuɓɓukan farar pixel iri-iri daga P0.93 zuwa P1.56mm don biyan bukatun masu amfani daban-daban.
