Dooro Xirfadaha Chip Module Isha Iftiinka

Qiimaha qaybaha isha iftiinka LED ayaa la sameeyay mustaqbalka dhow, LED-yada ayaa si weyn loogu aqoonsaday inay yihiin cagaar iyo nadiifinta ilaha iftiinka deegaanka. Ilaha iftiinka LED waxay leeyihiin nolol adeeg oo dheer, badbaadinta tamarta iyo badbaadinta tamarta, codsi fudud oo ku habboon, iyo kharashyada isticmaalka hooseeya. Sidaas daraaddeed. Horraantii 2008dii, shixnadaha kuraasta nalalka guriga ee sanadlaha ah ee adduunka waxay ahaayeen ilaa 50 bilyan yuan. Tiknoolajiyada ilaha iftiinka LED-ka ayaa noqday kuwo qaan-gaar ah, iyo qulqulka iftiinka foornada kasta ayaa si degdeg ah u kordhay, taas oo keentay inay hoos u dhigto qiimaha sanadba sanadka. Suuqa weyn iyo baahida kobaca xasilloon ee joogtada ah ee nalalka cagaaran ee LED waxay noqon doonaan suuqa tsunami ee warshadaha isku dhafka ah ka dib VCD, DVD, taleefannada gacanta, iyo MP3! Waxqabadka sare ee badbaadinta tamarta sare, nolosha dheer, iyo ilaalinta deegaanka ee nalalka LED ayaa guud ahaan la aqoonsan yahay. 1. LED tamarta sare -badbaadinta: darawalka DC, isticmaalka tamarta ultra-hooseeya (hal tube 0.03 1W) Beddelka tamarta korontada waxay ku dhowdahay 100, saameyn la mid ah nalalka ayaa ka badan 80% tamar ka badan -badbaadinta ilaha iftiinka dhaqameed. 2. Nolosha dheer ee LED: Isha iftiinka LED waxaa loo yaqaannaa iftiin dheer. Ilaha iftiinka qabow ee adag, baakadaha resin epoxy, oo aan lahayn qaybo dabacsan oo ku jira jidhka laambada. Ma jiraan wax cillado ah sida nalalka fiiloyinka, kulaylka dego, iyo iftiinka degdega ah. Ka badan. 3. Ilaalinta Deegaanka Ilaalinta ee LED: LED waa isha iftiinka cagaaran, faa'iidooyinka ilaalinta deegaanka ayaa ka wanaagsan. Ma jiraan shucaaca ultraviolet iyo infrared ee spectrum, kaloori yar iyo flash bilaash ah, shucaac la'aan, iyo qashinka dib ayaa loo warshadeyn karaa. Ma jirto wasakh la'aan mercury, ilo iftiin qabow, kuwaas oo si badbaado leh loo taaban karo. Waxay iska leedahay isha iftiinka cagaaran ee caadiga ah. Tilmaamaha shaqada ee moduleka isha iftiinka LED aad bay ugu hooseeyaan tamarta VF ee ilaha iftiinka LED. Caawinta ah waa 2.75 3.8V. Sidaa darteed, korantada wax soo saarka ee darawalka LED IC waa VFXN ama VFX1, iyo IF waxay ku hayaan socodka joogtada ah 15 1,400ma. Isha iftiinka LED-ka ee ay adeegsadaan nalalka LED-ku waxay leeyihiin laba nooc: awood yar (HADDII ay tahay 15 20mA) iyo awood sare (Haddii ay ka weyn tahay 200mA). LED koronto yar ayaa inta badan loo isticmaalaa sida nalalka cadceedda ee LED, nalalka qurxinta, iyo nalalka wax lagu duubo. LED-ga awoodda sare leh waxaa loo isticmaalaa nalka qoyska, nalalka iftiinka, nalalka hoose, nalalka gidaarka, nalalka waddooyinka, nalalka tunnel-ka, nalalka shaqada baabuurta, iwm. Isha nalka LED-ka ee korontada ku shaqeeya waa koronto yar iyo qalab weyn oo hadda wada. Awoodeeda iftiinka waxaa lagu go'aamiyaa socodka hadda socda ee LED-ka. Hadda waxa ay keeni doontaa dhunkashada iftiinka LED-ka, iyo hadda aad u yar waxa ay saameyn doontaa xoogga iftiinka LED-ka. Sidaa darteed, darawalka LED wuxuu u baahan yahay inuu bixiyo koronto joogto ah oo hadda jirta si loo hubiyo badbaadada LED-yada awoodda sare leh, isla markaana isla mar ahaantaana la gaaro xoojinta iftiinka ugu habboon. Dhinaca iftiinka LED-ka, si loo muujiyo sifooyinka tamarta tamarta iftiinka LED iyo nolosha dheer, waxaa muhiim ah in si sax ah loo doorto darawalka LED IC. La'aanta darawalka IC ee wanaagsan, faa'iidooyinka iftiinka LED ma muuqan karo. Ilaha iftiinka LED-ka ee nalka LED-ka ee nalka nalka LED-ka LED-ka koollada waraabka ee aan biyuhu lahayn ee Hongyan cabin saddex-hal qol LED isha iftiinka moduleka shurudaha loogu talagalay chips-ka wadida korantada ee hooseeya waa in lagu buuxiyaa kala duwanaanshaha korantada magacaabista ee chip wadista, DC 8 40V, si loo daboolo baahiyaha dalabka ee ballaaran. Awoodda iska caabinta cadaadiska ayaa ka weyn 45V. Marka gelinta uu yahay AC 12V ama 24V, korantada wax-soo-saarka buundada fudud ee rectifier-ga ayaa isbedbeddeli doonta korantada shabagga, gaar ahaan marka uu korontadu sarreeyo, korontadda DC-gu waxay noqon doontaa mid sare. Haddii darawalka IC uusan lahayn kala duwanaansho koronto oo ballaaran, waxaa badanaa la dhex geli doonaa marka korantada korantadu kor u kacdo, markaas oo gubanaya isha iftiinka LED. 2. Hadda wax soo saarka magaca ee chip-ka wadista wuxuu u baahan yahay in ka badan 1.2 1.5A. Sida isha iftiinka LED-ka ee nalka, wakhtiga xaadirka ah ee awoodda 1W ee isha iftiinka LED waa 350mA, iyo magaca shaqada hadda ee isha iftiinka LED ee awoodda 3W waa 700mA. Ilaha iftiinka LED-ka ee leh awood sare waxay u baahan tahay hadda weyn, markaa darawalka IC ee ay doorteen qalabka nalalka LED waa inuu lahaadaa wax soo saar ku filan hadda. Marka la naqshadeynayo alaabta, shaqada darawalka IC waa in loo isticmaalo in lagu shaqeeyo 70-90% ee goobta shaqada ugu fiican ee 70-90% ee wax soo saarka buuxa ee culeyska. Wadista ICs-yada iyadoo la isticmaalayo culeyska buuxa ee hadda jira laguma daalin meesha yar ee nalalka, taas oo si fudud u horseedi karta daal iyo hore u dhac ku yimaada laambada. 3. Hadda wax-soo-saarka chip-ka wadista waa inuu ahaadaa mid joogto ah, si ay LED-ku u iftiimiyaan si deggan oo aan biliglaynin. Dufcaddii isku midka ah ee chips-ka wadista ayaa loo adeegsadaa isla shuruudo isku mid ah, iyo wax-soo-saarkeedu waa inuu ahaadaa sida ugu macquulsan, taas oo ah, caqli-galnimadu waa inay noqotaa mid yar, si ay u hubiso waxtarka iyo nidaamka marka la soo saaro tiro badan oo wax soo saar otomaatig ah. khadadka. Chip gaar ah oo leh muujin gaar ah oo ka mid ah wax soo saarka hadda, waxaa lagama maarmaan ah in la doorto xulashada horteeda warshadda ama la geliyo khadka wax soo saarka, hagaajinta qiimaha caabbinta ee caabbinta goobta hadda ee guddiga PCB, si Laambadaha LED-ka looxa wadista joogtada ah ee joogtada ah ee uu soo saaro guddiga PCB Iftiinka iyo iftiinka iftiinka iftiinka ayaa ah mid joogto ah si loo ilaaliyo joogteynta alaabta dhamaadka.
