Mumunda wekurongedza kwe LED, COB inomiririra Chip paBhodhi, yakasanganiswa pamusoro pechiedza sosi tekinoroji inonamira LED machipi zvakananga kune substrate.LED mwenje sosi uchishandisa COB tekinoroji, iyo chip inobvisa zvakananga kupisa kune substrate, inomira yakakwira yekupisa simba density;chip dense kuronga, yakakwirira optical simba density;saizi yemuviri inopenya imwe idiki, yakanakira nzvimbo yekutengeserana yekuvhenekesa ine zvinodiwa zvakasimba pahukuru hwemwenje sosi.Kuenzaniswa nekamwe chip package LED zvishandiso, COB package akawanda machipisi, akawanda solder majoini, yakakwirira simba density zvakakonzerawo kuwedzera exponential mukuomerwa kwekurongedza.Zvinogona kutaurwa kuti COB mwenje sosi kune rumwe rutivi ndiyo inotungamira yekutengesa mwenje maapplication, kune rimwe divi, iriwo korona jewel ye LED yekurongedza munda.
Basa guru rechiedza chechiedza ndechekuvhenekera, kuti LED iwedzere muganhu panzvimbo yekuvhenekera - kuchengetedza simba, saka nhanho yekutanga yekuvandudzwa kweCOB light source zvakare mukutsvaga kushanda kwechiedza, nekuda kweCOB chiedza chinoshandisa simbi. -based circuit board kana ceramic substrate reflectivity haina kunaka sesilver-plated bracket, yakaderera reflectivity yakasimudzwa pamusoro pekubatanidzwa kwechiedza pakati pe multiple chips Absorption, COB light source luminous performance yakaderera pane SMD zvishandiso zvinopfuura 30%, uye gare gare kuunzwa kwegirazi aluminium substrate kugadzirisa dambudziko rekuratidzira, asi kubatwa kwemachipi akawanda kuchiri kuita kuti COB mwenje sosi inopenya ishande yakaderera pane discrete zvishandiso.Iine chip kunze kweiyo quantum kunyatsoshanda uye phosphor mwenje kushandura kunyatsoita, COB mwenje sosi inopenya yakasvika indasitiri kugamuchirwa kwe "inotapira nzvimbo" - 100lm / W, kusvika kweiyi nzvimbo inotapira pane discrete zvishandiso zvakaunganidzwa mwenje sosi makore 2-3 gare gare.
Muzviitiko zvakasiyana, kushandura tembiricha yemuvara wemwenje sosi kunogona kuunza zvirinani ruzivo rwemwenje.Kana pasina nzvimbo inogumira, zviri nyore kuona shanduko yekushisa kweruvara, chero bedzi iyo yakakwira uye yakaderera ruvara tembiricha michina yakasanganiswa uye inofambiswa zvakasiyana, shanduko yekushisa kweruvara yeCOB mwenje sosi zvakare ipfungwa imwe chete, machipisi ari mukati. COB mwenje sosi yakakamurwa kuita mapoka maviri uye yakaputirwa nemhando dzakasiyana uye yakasanganiswa phosphor, kuitira kuti mapoka maviri emachipisi abudise akasiyana tembiricha chena mwenje.Shandura saizi yazvino yemapoka maviri emachipisi, unogona kuita kuti sosi yemwenje ibudise tembiricha yemavara chena.diki saizi yeCOB mwenje sosi, mushure mekunge mwenje usingagoni kuona maviri akasiyana mavara tembiricha yechiedza-emitting point, asi yunifomu yechiedza-emitting nzvimbo, inova mukana weCOB mwenje sosi, asi diki saizi, asiwo kune kugadzirwa kwemavara kusanganisa COB mwenje sosi kwakonzera nyonganiso yakawanda.Mushure memakore ekuongorora, kune akasiyana chip zvimiro, vanhu vakagadzira nekuvandudza akati wandei matekinoroji akadai sekudhinda, kupfapfaidza, uye fluorescent machipisi kuti awane yakagadziriswa domain uye kuwanda kwekuputira kwemhando dzakasiyana dzephosphors muCOB magetsi masosi.
Mhando uye mareshiyo emhando mbiri dzetembiricha tembiricha fluorescent glue mune colour-tuning COB mwenje sosi inogadziridzwa kuti iwane yakakwirira inooneka index uye yakanyanya kupenya inopenya mune yese shanduko yeruvara.Mufananidzo 2 unoratidza ma spectral curves emhando yepamusoro uye yakaderera tembiricha ye COB inoshandura ruvara sosi inopihwa neLightSense Semiconductor.Iyo phosphor yeichi mwenje sosi yakagadziridzwa kuitira kuti iyo color rendering index isvike kupfuura makumi mapfumbamwe neshanu pane chero tembiricha yeruvara panguva yekuchinja-ruvara kwe3000-6000K, uye iyo R9 index, iyo inonyanya kunetseka, yakakura kupfuura makumi masere.
Kugadziriswa kwetembiricha yeruvara kunowedzera nzvimbo yekushandisa yeCOB mwenje sosi, asi iwo ruvara rwakawanikwa muruvara gamut dhayagiramu rinogona kungoonekwa mune yakakwira uye yakaderera ruvara tembiricha yemavara coordinates pamutsetse une doti.Mumunda wekuvhenekesa mwenje, kushandiswa kweakasiyana mavara kurongeka kwenzvimbo yekuvhenekesa, iwe unogona kuratidza maitiro ekuona emhando dzakasiyana dzezvinhu kusangana nezvinodiwa zvevanhu, kubva pakuona uku, kungogadziriswa kwemavara tembiricha kana kusakwana, mukati. iyi kesi, nekugona kugadzirisa iyo color gamut yeCOB light source yakazvarwa.
