Iyo Yekupedzisira Inotungamira kune SMD LED Kuvandudza Trend uye Mashandisiro Ayo

Iyo tekinoroji yekuseri kwemwenje ye LED parizvino iri kuitika munguva yekukurumidza kusimudzira, uye kupenya kwakanaka kuri kuramba kuchienderera mberi. Makore maviri ega ega, huwandu hwekupenya hunopenya hunogona kugadzirwa neamwechete LED package mudziyo unowedzerwa nechikamu chezviviri. Kubva kuma1980, pave nekuwedzera zvishoma nezvishoma mukusimudzirwa kwekushandiswa kwepamusoro-yakaiswa michina mukugadzirwa kwe LED. Kana zvasvika pakuvhenekera, iyo high simba SMD LED izvo zvakazogadzirwa zvino ndizvo zvinoshandiswa kuvheneka mota panji, mabhureki mwenje, uye yakatowedzerwa kune yakajairwa mwenje michina.

SMD LED musika mamiriro

Kana zvichionekwa kubva pakuona kwepasirese, kugadzirwa kwekutakura muChinese Taiwan kunotora zvikamu makumi matanhatu kubva muzana zvemugove wenyika. Kugadzirwa uye kushambadzira kweiyo indasitiri cheni yakatsiga, kunyanya maererano nechikamu chekurongedza, uye pane kupatsanurwa kwakajeka kwevashandi pakati pemabhizinesi ekumusoro, epakati, uye akadzika. Kana kugadzirwa kuchiendeswa kumahombekombe, mutengo wekugadzira unodzikira, zvichibvumira kukwikwidza zviri nani nedzimwe nyika. Zvinotarisirwa kuti mukati memakore mashanu kusvika gumi anotevera, Yangtze River Delta, Pearl River Delta, Fujian, nedzimwe nzvimbo dzichava nzvimbo dzepasi rose dzekugadzirwa kwemvura. UV LED kurongedza

Iyo yemuno SMD LED musika yave yakagadzikana nguva pfupi yadarika kubva pakuona kwemusika weChina mainland.

Hunhu hwe encapsulation inoshandiswa muSMD LEDs

Iyo phosphor uye epoxy resin zvinotanga kugadzirwa kugadzira mold yeSMD LED, inova nhanho yekutanga mu encapsulation process. Zvadaro, epoxy resin uye phosphor powder zvinosanganiswa kuita keke yeglue, iyo inobva yanamatira kune chip. Chekupedzisira, iyo nzvimbo yakasara yakatenderedza chip yakazadzwa ne epoxy resin kugadzira iyo SMD yakarongedzwa LED.

Mazuva ano, iyo yakajairika SMD LED pamusika yakarongedzerwa neatatu machipisi e LED, uye mapini matanhatu akawedzerwa, ayo akabatana nepamusoro pePCB redunhu bhodhi. Iyi LED ine saizi yekunze ye50mm x 50mm. Inosungirirwa zvakananga pamusoro pemvura inopisa uchishandisa thermally conductive adhesive, izvo zvinoguma nekuvandudzwa kukuru mukupisa kupisa, kuvimbika, uye kuderedzwa kwehuwandu hwekuora kwechiedza. Substrates dzakagadzirwa nesimbi-ceramic composites ine yakanaka yekupisa conductivity ndiyo inowanzo shandiswa kune yakakwirira-simba LEDs. Aya ndiwo maitiro ekutanga:

(1) Iyo yakakwirira yekupisa conductivity uye yakaderera kupisa kupisa;

(2) Kuenderana kweiyo coefficient yekuwedzera kwekushisa (TCE: 6.2);

(3) Anti-ultraviolet;

(4) Resistance Corrosion, pamwe nekusavapo kweyero;

(5) Teerera kune maitiro akaiswa neROHS;

(6) Kukwanisa kutsungirira kupisa kwakanyanya.

Kupokana kwekupisa kweiyo LED encapsulation ine mhedzisiro yakakosha pahupenyu hweiyo LED chip, kunyanya maererano neiyo LED chip iyo inoiswa kune yakakwira ikozvino. Chimiro chebhuraketi rekurongedza chinotarisa mutengo uye kupisa kupisa kuita kweLED encapsulation zvigadzirwa, uye chimiro chebhureki rekurongedza chiri kusimuka munzira yehukuru hudiki, hutete hwakakora, uye yakanaka kupisa kupisa. Izvi zvakakosha nekuti mutengo we LED encapsulation products wakanangana nekuita kupisa kwekupisa kwechigadzirwa.

Pakurongedza mamwe machipisi e LED mune imwechete SMD LED, nyaya yekupisa kupisa chinhu chinofanira kutariswa. Iyo yekupedzisira-yakaderera kupisa kwekudzivirira inopihwa neakakwira-simba SMD LEDs ayo ma substrates akagadzirwa nepamusoro ekupisa conductivity simbi-ceramic composites ndiyo inonyanya kukosha inopihwa nemwenje iyi. Nekuda kwehukuru hwayo compact uye hutete chimiro, iyo yekupedzisira-yakaderera kupisa kwekudzivirira uye yakakwirira-simba LED chip package inokodzera zvirinani kushandiswa mumashandisirwo ane nzvimbo shoma inowanikwa. Zvishandiso zvakawanda zvinogona kubatsira zvakanyanya kubva mukushandisa iyi mashandiro.

Kusiyana pakati peSMD LEDs uye DIP LEDs

Iyo yepamusoro-Mount mudziyo (SMD) LED inonamirwa kumusoro kwebhodhi redunhu, ichiita kuti ive yakakodzera kune yepamusoro-gomo tekinoroji (SMT) kugadzirisa pamwe nereflow soldering. Ma LED ane surface-mount diodes (SMD) anopa kuvandudzwa maererano nekupenya, kuona kona, flatness, kuvimbika, uye kuwirirana. Yayo yakanakisa vibration kuramba, yakaderera solder joint kukanganisa mwero, uye yepamusoro-yepamusoro-frequency maitiro ndemamwe ezvakanakira ayo kana achienzaniswa neayo emamwe maturusi akaputirwa.

Iyo in-line LED inoshandisa potting seyayo yekurongedza zvinhu. Nhanho yekutanga mukugadzira poto ndeyekupinza mvura epoxy resin mugomba re LED mold, inoteverwa nekuiswa kweiyo pressure-welded LED bracket. Mushure meizvozvo, gungano rinoiswa muchoto kurapa epoxy resin, uye pakupedzisira, iyo LED inoumbwa mushure mekubviswa kubva mugomba rekuumbwa. Mugove wayo wakasimba wemusika unogona kuverengerwa kune ese ari maviri nzira yakatwasuka yekugadzira uye nemitengo yemakwikwi.

Nemhaka yokuwedzera nokukurumidza kwoupfumi munyika yose, pari zvino pane dikanwo yokukurumidzira yokuwana chigadzikiso chechinetso chenyika yose chokushaikwa kwesimba rinoshandiswa. Kushandiswa kwechiedza kunosvika makumi maviri muzana emagetsi ese anoshandiswa. Chimwe chezvinhu zvinonyanya kukosha zvinogona kuitwa kuchengetedza simba kudzikisa huwandu hwesimba rinoshandiswa pakuvheneka. Shanduko kubva kune yakajairwa mwenje masosi iri kukwidziridzwa nekushandiswa kwemarambi e-LED asingashandisi simba, ayo anoshanda sechinotsiva kwechinyakare incandescent mwenje.
