Warshadaha elektaroonigga ee maanta si xawli ah u koraya, isku halaynta qaybaha iyo waxqabadka ayaa muhiim ah. Taxanaha YMIN Electronics ee kaabsoosha elektaroonigga ah ee aluminiumka LED waxaa loogu talagalay codsiyada waxqabadka sare leh ee jawiyada adag, gaar ahaan nalalka, sahayda korontada warshadaha, iyo elektarooniga baabuurta.
Astaamaha Badeecada ee aadka u Fiican
Kaadhadhkayaga elektaroonigga ah ee aluminiumka ah, oo lagu sameeyay tiknoolajiyadda elektrolytka dareeraha ah ee horumarsan iyo agab tayo sare leh, waxay bixiyaan astaamo gaar ah. Waxay si joogto ah ugu shaqeeyaan heerkul ballaaran oo u dhexeeya -25°C ilaa +130°C, waxayna leeyihiin kala duwanaansho danab oo la qiimeeyay oo ah 200-500V, taasoo daboolaysa baahiyaha inta badan codsiyada danab-sare. Dulqaadka awoodda waxaa lagu xakameeyaa ±20%, taasoo hubinaysa saxnaanta iyo isku-dheellitirka naqshadaynta wareegga.
Waxa ugu muhiimsan waa waxqabadkooda heerkulka sare: waxay bixiyaan hawlgal joogto ah muddo 2,000 saacadood ah 130°C iyo ilaa 10,000 saacadood ah 105°C. Iska caabbinta heerkulka sare ee gaarka ah waxay ka dhigaysaa mid si gaar ah ugu habboon codsiyada nalalka LED-ka heerkulka sare leh, sida nalalka waddooyinka ee awoodda sare leh, nalalka warshadaha, iyo nidaamyada nalalka ganacsiga ee gudaha.
Tilmaamaha Farsamo ee Adag
Badeecooyinkeenu waxay buuxiyaan heerarka AEC-Q200 waxayna u hoggaansamaan RoHS, taasoo muujinaysa sida aan uga go'annahay ilaalinta tayada iyo deegaanka labadaba. Korontada daadashada aad bay u hooseysaa, iyadoo u hoggaansan heerka ≤0.02CV+10(uA), halkaas oo C ay tahay awoodda magacaaban (uF) iyo V ay tahay danabka la qiimeeyay (V). Qiimaha luminta wuxuu u dhexeeyaa 0.1-0.2 iyadoo ku xiran danabka. Xitaa alaabada leh awood ka badan 1000uF, kororku waa 0.02 oo keliya 1000uF oo dheeraad ah.
Kaabayaasha waxay sidoo kale bixiyaan astaamo heer sare ah oo ku saabsan saamiga iska caabinta, iyagoo ilaalinaya saamiga iska caabinta inta u dhaxaysa 5-8 gudaha heerkulka -40°C ilaa 20°C, taasoo hubinaysa waxqabad aad u wanaagsan xitaa jawiga heerkulka hooseeya. Tijaabada waarta waxay muujineysaa in ka dib marka la soo bandhigo danabka la qiimeeyay iyo qulqulka gariirka ee 130°C, isbeddelka awoodda ayaa ku sii jira ±20% qiimaha bilowga ah, halka qiimaha luminta iyo qulqulka daadashada labaduba ay ka yar yihiin 200% qiimayaasha la cayimay.
Codsiyada Ballaaran
Darawalada Nalalka LED-ka
Kaadhadhkayagu waxay si gaar ah ugu habboon yihiin sahayda korontada darawalka LED-ka, iyagoo si wax ku ool ah u shaandheeya buuqa soo noqnoqda ee sare iyo bixinta koronto deggan oo DC ah. Hadday tahay in loo isticmaalo nalalka gudaha ama nalalka waddooyinka ee dibadda, waxay hubiyaan hawlgal xasilloon oo muddo dheer ah waxayna yareeyaan kharashyada dayactirka.
Nidaamyada Korontada Warshadaha
Qaybta korontada warshadaha, alaabtayada waxaa loo isticmaali karaa aaladaha sida beddelka sahayda korontada, qalabka wax lagu beddelo, iyo qalabka wax lagu beddelo ee soo noqnoqda. Astaamaha ESR ee hooseeya waxay gacan ka geystaan yareynta khasaaraha korontada iyo hagaajinta waxtarka guud ee nidaamka.
Elektaroonikada Gawaarida
U hoggaansanaanta heerarka AEC-Q200 waxay u suurtagelinaysaa alaabtayadu inay buuxiyaan shuruudaha adag ee isku halaynta ee elektaroonigga baabuurta waxayna ku habboon yihiin codsiyada sida nidaamyada korontada ee saaran, cutubyada xakamaynta ECU, iyo nalalka LED-ka.
Qalabka Isgaarsiinta
Saldhigyada saldhigga isgaarsiinta iyo qalabka, capacitors-kayadu waxay bixiyaan shaandheyn awood oo deggan, taasoo hubinaysa calaamadaha isgaarsiinta oo cad oo deggan.
Faahfaahinta Badeecada oo Dhameystiran
Waxaan bixinaa khad badeeco oo dhammaystiran, oo daboolaya noocyo badan oo kala duwan oo ah fursadaha awoodda laga bilaabo 2.2μF ilaa 68μF marka la gaaro 400V. Tusaale ahaan, qaabka 400V/2.2μF wuxuu cabbiraa 8×9mm, wuxuu leeyahay ugu badnaan impedance 23Ω, iyo hadda gariirka oo ah 144mA. Qaabka 400V/68μF, dhanka kale, wuxuu cabbiraa 14.5×25mm, wuxuu leeyahay impedance oo ah 3.45Ω oo keliya, iyo hadda gariirka oo ah ilaa 1035mA. Khad badeeco oo kala duwan ayaa u suurta gelinaya macaamiisha inay doortaan badeecada ugu habboon baahiyahooda gaarka ah ee codsiga.
Hubinta Tayada
Dhammaan alaabtu waxay maraan tijaabo adag oo ku saabsan cimri dherer iyo kaydinta heerkulka sare. Ka dib 1000 saacadood oo kaydin ah 105°C, heerka isbeddelka awoodda badeecadda, lumitaanka tangent, iyo daadinta hadda dhammaantood waxay buuxiyaan heerarka la cayimay, taasoo hubinaysa isku halaynta badeecada muddada dheer.
Waxaan sidoo kale bixinnaa isku-xidhka sixitaanka soo noqnoqoshada iyo heerkulka oo faahfaahsan si loo fududeeyo injineerada inay si sax ah u xisaabiyaan qiimayaasha hadda socda ee ku jira xaalado shaqo oo kala duwan. Isku-xidhka sixitaanka soo noqnoqoshada wuxuu u dhexeeyaa 0.4 at 50Hz ilaa 1.0 at 100kHz; isku-xidhka sixitaanka heerkulku wuxuu u dhexeeyaa 2.1 at 50°C ilaa 1.0 at 105°C.
Gunaanad
Kaabayaasha elektrolytic-ga ee YMIN aluminium waxay isku daraan waxqabad sare, isku hallayn sare, iyo cimri dheer, taasoo ka dhigaysa xulasho ku habboon codsiyada sida nalalka LED-ka, sahayda korontada warshadaha, iyo elektarooniga baabuurta. Waxaan ka go'an nahay inaan macaamiisha siino alaabooyin iyo adeegyo tayo sare leh iyo inaan si wadajir ah u horumarinno horumarinta warshadaha elektaroonigga ah.
