Istaraatiijiyaddee LED Patch iyo laambada nalka LED-ka ayaa ka wanaagsan?

Iyadoo horumarinta degdega ah ee tignoolajiyada LED-ka, nalalka LED-ka ayaa si tartiib tartiib ah u noqday doorashada ugu fiican ee iftiinka cagaaran ee cusub. LED-ku aad ayuu uga fiican yahay alaabada iftiinka dhaqameed ee heerka mabda'a iftiinka, badbaadinta tamarta iyo ilaalinta deegaanka. Nalalka LED-ka waxaa loo qaybin karaa balastar iyo laambad. Maxay ku kala duwan yihiin labadaba? Xiaobian wuxuu ka hadlayaa haddii ay tahay dhejiyeyaasha nalalka LED ama kuulka laambada. Marka hore, aynu eegno sifooyinka laambada LED? Xagasha kuulka nalka LED aad buu u yar yahay. Waxay iska leedahay iftiinka badan ee xoogga badan, baaxadduna waa fog tahay, laakiin baaxadda shucaaca ayaa xaddidan. Waxay ka tirsan tahay kala firdhisanaanta iftiinka iyo shucaaca ballaaran, laakiin baaxaddu waa mid aad u dhow. Kuullaha nalalka LED-ku waxay isticmaalaan dareere iyo iftiin, halka balastar LED loo isticmaalo dhalaal qabow. Laambadaha balastarrada LED waxay ka samaysan yihiin guddiga wareegga FPC, iftiinka LED, gacmo silikoon tayo sare leh. Waxqabadka biyuhu, isticmaal badbaadada sahayda korantada DC ee hooseeya-voltage, midab ku habboon, midab kala duwan, midabyo dhalaalaya; Isticmaalka bannaanka wuxuu u adkeysan karaa gabowga UV, jaalaha, iyo heerkulka sare. Alaabtan waxaa si weyn loogu isticmaalaa dhismaha nalalka contour, iftiiminta qurxinta saxda ah ee goobaha madadaalada, qurxinta xayaysiinta, qurxinta xayaysiinta Iftiinka beerta. Taas bedelkeeda, maxay yihiin faa'iidooyinka balastarku? Patch LED sidoo kale waa nooc ka mid ah laambada LED-ka. LED-yada caadiga ah waxaa ka mid ah laba ama afar irbadood, mana jiraan cago qaabaysan oo irbad leh. Furaha doorashada kuulka laambada waa in la tixgeliyo heerkulka midabka, tusaha samaynta midabka, saamaynta iftiinka, cilladda iftiinka, iyo tayada tamarta, iwm., iibso waxyaalahan oo iibso waxyaalahan. Soosaarayaasha Zhuhai waxay sannado badan oo khibrad farsamo ah u leeyihiin warshadaha LED-ka, ardayduna waxay soo saaraan dhejisyada nalalka LED-ka. Tayada waa la dammaanad qaaday, soo saarayaasha ayaa ah kuwo tiro badan oo la soo saaray, qiimayaashuna waa kuwo wanaagsan. Awoodda kuulyada nalalka LED-ka ee kala duwan ee tamarta sare ee LED guud ahaan waxay isticmaalaan 1W tamarta sare ee nalalka LED-ka, 1-3W wada noolaanshaha tamarta sare ee nalalka LED-ka, COB awood sare leh kuwan. Kuulaha laambada ultra-power-ka ah ee hal awood LED ah ayaa lagu kordhin karaa 200w ama ka badan. Nalalka yar-yar ee LED-ka waxaa guud ahaan loo adeegsadaa kuul laambadaha, kuwaas oo inta badan ay ku jiraan kuwan: 5050 laambadood, 0.2W midkii, 3528 laambadood, 0.06W kasta, 3014 nalalka, 0.1W kasta, 5630 nalalka, mid kasta, 5630 laambadood, mid kasta , 5630 laambadood, midkiiba, 5630 laambadood, iyo 5630 laambadood, midkiiba, 5630 laambadood, iyo 5630 laambadood. 0.5W midkiiba, 5730 laambad, 0.5W midkiiba. Marka loo eego kharashka badeecada, qiimaha tamarta sare ee nalalka LED-ka ayaa ka sarreeya qiimaha tamarta hoose. Mid waa in qiimaha tamarta sare ee LED laftiisa uu sarreeyo; Midda kale waa in LED-ga awoodda sare leh lagu daro weel kuleyl oo aluminium ah, awoodda yarna waxay u baahan tahay oo kaliya in loo isticmaalo si caadi ah. Guddiga wareegga, oo lagu daray kuleylka dabiiciga ah ayaa buuxin kara shuruudaha. LED-ga awoodda sare leh ayaa asal ahaan loo isticmaalaa alaabooyinka u baahan ilo iftiin sare leh oo ku yaal aagga cutubka, sida nalalka saqafka LED, nalalka iftiinka LED, goobooyin LED, nalalka waddooyinka, iwm. Nalalka yar-yar ee LED-ka waxaa asal ahaan loo adeegsadaa alaabada leh meel yar oo balastar ah iyo daadinta kulaylka liita. Waxay u baahan tahay shuruudo yar-yar oo loogu talagalay isha iftiinka ee aagga unugga, sida nalalka saqafka ee LED, nalalka dhaadheer ee LED, nalalka LED-ka, xargaha iftiinka LED-ga Sug. Laydhka LED-ka, maxay faa'iido u leedahay? Kuullaha nalalka LED-ka ayaa si toos ah loo geliyey loona balamay. Iyada oo la horumarinayo horumarka tignoolajiyada, jajabyo badan oo nalalka LED-yada ah ayaa soo muuqda, oo si toos ah ugu dhexjira substrate-ka (wareegga, naqshadaynta kulaylka) Walxaha iftiimaya ee awoodda sare leh, tani waa tan “COB ”(Waxay u muuqataa sida kuul laambad, taas oo dhab ahaantii ah set of laambad kuul). Oo balastarkii, maxay faa'iido u leedahay? Isku-dhafka LED-ka guud ahaan waa magac kale oo loogu talagalay isha iftiinka COB ee suuqa, laakiin dhab ahaantii, sifooyinka ilaha iftiinka COB si cad looma sifeyn karo. COB waxaa loola jeedaa Chip-on-Buard, kaas oo si toos ah ugu xirxiray jajabka tamarta yar ee saxanka ku salaysan aluminium si uu si dhakhso ah u baabi'iyo kulaylka, aagga jajabku waa yar yahay, waxtarka kuleylka kulaylka ayaa sarreeya, hadda darawalkuna waa yar yahay. Sidaas daraaddeed. Marka la barbar dhigo sifooyinka SMD caadiga ah ilaha iftiinka yar yar: dhalaalka sare, caabbinta kulaylka yar (
