The Ultimate Guide To SMD LED Development Trend Le Tšebeliso ea Eona

Theknoloji ea mabone a LED hajoale e ntse e tsoela pele ka potlako, 'me katleho e khanyang e ntse e tsoela pele. Lilemo tse ling le tse ling tse peli, palo ea khanya e khanyang e ka hlahisoang ke sesebelisoa se le seng sa sephutheloana sa LED e eketseha ka makhetlo a mabeli. Ho tloha lilemong tsa bo-1980, ho bile le keketseho butle-butle khothatsong ea tšebeliso ea lisebelisoa tse phahamisitsoeng holim'a tlhahiso ea li-LED. Ha ho tluoa tabeng ea ho khantša, the matla a phahameng a SMD LED e ileng ea hlahisoa ka mor'a moo ke eona e sebelisetsoang ho bonesa liphanele tsa koloi, mabone a mariki, 'me e se e fetiselitsoe lisebelisoa tsa mabone a tloaelehileng.

Boemo ba marakeng ba SMD LED

Ha ho bonoa ka pono ea lefats'e ka bophara, tlhahiso ea liphutheloana ka Sechaena Taiwan e nka karolo ea mashome a tšeletseng lekholong ea karolo ea lefats'e. Likarolo tsa tlhahiso le thekiso ea ketane ea indasteri li tsitsitse, haholo-holo mabapi le lekala la liphutheloana, 'me ho na le karohano e hlakileng ea basebetsi lipakeng tsa likhoebo tse holimo, tse bohareng le tse tlase. Ha tlhahiso e fallisetsoa naheng e kholo, theko ea tlhahiso e tla fokotseha, e leng se tla etsa hore e hlōlisane hantle le linaha tse ling. Ho lebelletsoe hore nakong ea lilemo tse hlano ho isa ho tse leshome tse tlang, Nōka ea Yangtze Delta, Pearl River Delta, Fujian, le libaka tse ling e tla ba litsi tsa lefats'e tsa tlhahiso ea Sephutheloana sa UV LED

Mmaraka oa lehae oa SMD LED o ntse o tsitsitse haufinyane ho latela pono ea mmaraka oa naha ea China.

Litšobotsi tsa encapsulation e sebelisoang ho li-LED tsa SMD

Phosphor le epoxy resin li hlophisitsoe pele ho etsa hlobo bakeng sa SMD LED, e leng mohato oa pele oa ts'ebetso ea encapsulation. Ka mor'a moo, epoxy resin le phosphor phofo li kopantsoe ho etsa kuku ea sekhomaretsi, e ntan'o khomarela chip. Qetellong, sebaka se setseng se pota-potileng chip se tlatsitsoe ka resin ea epoxy ho theha LED e pakiloeng ea SMD.

Matsatsing ana, SMD LED e tloahelehileng 'marakeng e kentsoe ka li-chips tse tharo tsa LED,' me ho atolosoa lithakhisa tse tšeletseng, tse hokahaneng le boto ea potoloho ea PCB. LED ena e na le boholo ba kantle ba 50mm x 50mm. E tlamahane ka ho toba holim'a mocheso oa mocheso o sebelisa sekhomaretsi sa thermally conductive, se hlahisang ntlafatso e kholo ea ho senya mocheso, ho tšepahala, le ho fokotseha ha lebelo leo leseli le senyehang ka lona. Li-substrates tse entsoeng ka metsoako ea tšepe-ceramic e nang le conductivity e ntle ea mocheso hangata ke tsona tse sebelisetsoang li-LED tse matla a phahameng. Tsena ke litšobotsi tsa mantlha:

(1) Boemo bo phahameng ba conductivity ea mocheso le ho hanyetsa mocheso o tlaase;

(2) Ho lumellana ha coefficient ea ho atolosoa ha mocheso (TCE: 6.2);

(3) Anti-ultraviolet;

(4) Resistance Corrosion, hammoho le ho ba sieo ha mosehla;

(5) Khomarela mekhoa e behiloeng ke ROHS;

(6) Bokhoni ba ho mamella mocheso o phahameng.

Ho hanyetsa mocheso oa encapsulation ea LED ho na le phello e kholo bophelong ba chip ea LED, haholo-holo mabapi le chip ea LED e tlas'a boemo bo phahameng ba hona joale. Sebopeho sa sephutheloana sa liphutheloana se etsa qeto ea litšenyehelo le ts'ebetso ea ho qhala mocheso oa lihlahisoa tsa encapsulation tsa LED, 'me sebopeho sa sephutheloana sa liphutheloana se ntse se fetoha ka lehlakoreng la boholo bo bonyenyane, botenya bo tšesaane, le mocheso o motle oa mocheso. Sena ke sa bohlokoa hobane litšenyehelo tsa lihlahisoa tsa LED tsa encapsulation li lekana ka ho toba le ts'ebetso ea ho senya mocheso oa sehlahisoa.

Ha o paka li-chips tse ling tsa LED ho LED e le 'ngoe ea SMD, taba ea ho felloa ke mocheso ke ntho e lokelang ho nahanoa. The ultra-low thermal resistance e fanoang ke li-LED tsa SMD tse nang le matla a phahameng ao li-substrates li entsoeng ka metsoako e phahameng ea mocheso oa tšepe-ceramic ke molemo o moholo ka ho fetisisa o fanoang ke mabone ana. Ka lebaka la boholo ba eona bo kopaneng le profil e batlang e le tšesaane, sephutheloana sa "ultra-low thermal resistance" le sephutheloana sa chip sa LED se nang le matla a phahameng se loketse ho sebelisoa lits'ebetsong tse nang le sebaka se lekanyelitsoeng se fumanehang. Lisebelisoa tse ngata li ka rua molemo haholo ka ho sebelisa ts'ebetso ena.

Phapang lipakeng tsa li-LED tsa SMD le li-LED tsa DIP

Sesebelisoa sa sefahleho sa sefahleho (SMD) LED se khomaretsoe ka holim'a boto ea potoloho, e leng se etsang hore e tšoanelehe bakeng sa ts'ebetso ea thekenoloji ea holim'a metsi (SMT) hammoho le reflow soldering. Li-LED tse nang le li-surface-mount diodes (SMD) li fana ka lintlafatso mabapi le ho khanya, angle ea ho shebella, ho bata, ho tšepahala, le ho tsitsisa. E 'ngoe ea melemo ea eona ha e bapisoa le lisebelisoa tse ling tse pakiloeng, e khona ho mamella ho sisinyeha ha eona hantle, sekhahla se tlase sa "solder joint" le litšobotsi tse phahameng tsa maqhubu a holimo.

The in-line LED e sebelisa potting e le thepa ea eona ea ho paka. Mohato oa pele oa ho kenya lipitsa ke ho kenya mokelikeli oa epoxy resin ka mokoting oa hlobo ea LED, 'me ho lateloe ho kenngoa ha bracket e entsoeng ka khatello ea LED. Ka mor'a moo, kopano e behoa ka ontong ho phekola epoxy resin, 'me qetellong, LED e thehoa ka mor'a hore e tlosoe ka har'a hlobo ea hlobo. Kabelo ea eona e matla ea 'maraka e ka hlahisoa ka bobeli ke mokhoa o otlolohileng oa tlhahiso le litheko tsa tlholisano.

Ka lebaka la keketseho e potlakileng ea moruo lefatšeng ka bophara, hona joale ho na le tlhokahalo e potlakileng ea ho fumana tharollo bothateng ba lefatše ka bophara ba khaello ea phepelo ea motlakase. Tšebeliso ea khanya e ka ba liperesente tse mashome a mabeli tsa tšebeliso ea motlakase ka kakaretso. E 'ngoe ea lintho tsa bohlokoa ka ho fetisisa tse ka etsoang ho boloka matla ke ho theola matla a sebelisoang ho khantša. Phetoho ea ho tloha mehloling e tloaelehileng ea leseli e ntse e potlakisoa ke tšebeliso ea mabone a LED a sebetsang hantle, a sebetsang e le sebaka sa mabone a tloaelehileng a incandescent.
