Iyada oo kobaca degdega ah ee iftiinka LED-ka ee elektiroonigga baabuurta, caqabado cusub oo LED ah ayaa soo baxay.Maqaalkani waxa uu qeexayaa caqabadaha ugu waaweyn ee ay wajahayaan naqshadeeyayaasha awoodda iftiinka ee maanta oo sahaminaya sida kuwan wax looga qaban karo MPS' module LED-ka baabuurta cusub - MPM6010-AEC1 3.
Faa'iidooyinka nolosha dheer, cabbirka yar, iyo isticmaalka tamarta yar ee LED-yadu waxay ku habboon yihiin baahida baabuurta maanta deegaanka u wanaagsan waxayna gacan ka geysteen caannimada LED-yada iftiinka baabuurta.Laga soo bilaabo nalka deegaanka, tilmaamayaasha calaamadaha, iyo iftiinka dambe ee shaashadda dhijitaalka ah ee gudaha baabuurka si loo rogo calaamadaha, nalalka biriiga, nalalka ceeryaamada ah, iyo nalalka socda ee maalintii ee dibadda baabuurka, LED-yada ayaa horayba loogu isticmaalay meel kasta gudaha iyo dibaddaba.Mustaqbalka dhow, LED-yada ayaa sidoo kale la filayaa inay beddelaan halogen ama xenon-ku-saleysan nalalka hore ee tamarta sare leh.
Injineerada nalalka baabuurta ee maanta waxay la kulmaan caqabado farsamo oo dhowr ah xagga naqshadeynta LED-yada si ay u noqdaan kuwo yar oo gaar ah, isla markaana hagaajinaya isku halaynta, ka hortagga faragelinta elektromagnetic, iyo hagaajinta waxqabadka kulaylka.
Kalsoonida sare waxay udub dhexaad u tahay injineernimada baabuurta, tanina waxay si gaar ah muhiim ugu tahay iftiinka baabuurka dibadda, kaas oo heerka gaadhigu ku xidhan yahay (rogid, joogsi, alaarmiga, iwm.)Mabda'a guud ee sare u qaadida isku halaynta waa in la yareeyo tirada qaybaha ku jira guddiga: qaybaha yar, dhibcaha yar ee suurtagalka ah ee fashilka, iyo walxaha yar ee loo baahan yahay.Sida fudud ee naqshaddu, way sahlan tahay in la komiyo oo la keeno suuqa.
Intaa waxaa dheer, sida nidaamyada LED-ku hoos u dhacaan, qalabka elektaroonigga ah ee la xidhiidha iyaga waa in sidoo kale hoos u dhaco.Mid ka mid ah dariiqooyinka caadiga ah ee lagu gaaro naqshadaha guddiga yaryar waa in la kordhiyo inta jeer ee beddelka darawalka, taas oo hoos u dhigaysa xajmiga inductor iyo capacitors ee la xidhiidha.Si kastaba ha ahaatee, isbeddellada sare ee isbeddelka ayaa sababa koror aad u sarreeya faragelinta korantada;xiriirka labajibaaran ee ka dhexeeya faragelinta korantada iyo inta jeer ee beddelidda macnaheedu waa in labanlaabista inta jeer ee beddelka ay kordhiso faragelinta korantada afar laab.Si loo xalliyo dhibaatadan, naqshadeeyayaashu waa inay wanaajiyaan qaabka wareegga oo ay doortaan qaybaha khasaaraha hooseeya iyagoo yareynaya wareegyada xasaasiga ah halkaasoo qulqulka ku-meel-gaadhka ah ay firfircoon yihiin;Waddooyinkan xasaasiga ah waxay sida caadiga ah ka kooban yihiin furayaasha, inductors kaydinta tamarta, iyo furayaasha kala goynta.Siyaabo kale oo lagu dhimi karo EMI waa in lagu daro gaashaanka birta, taas oo dabcan la socota kor u kaca qiimaha, taas oo aan la aqbali karin suuqa iftiinka xasaasiga ah.
Intaa waxaa dheer, in kasta oo LED-yadu ay ka awood yar yihiin nalalka halogen ama nalalka, maaraynta kulaylka ayaa weli ah arrin weyn maadaama ay si toos ah ula xiriirto rajada nolosha LED-ka.Nalalka LED-yadu waxa ay caan ku yihiin boqollaal kun oo saacadood oo ay shaqeeyaan, laakiin heerkulka is-goysyada oo sarreeya waxa uu sababi karaa in noloshooda hoos u dhacdo, xaaladaha cimilada adag ee ay baabuurtu ku shaqayn karaana waxa ay sii yaraan kartaa nolosha LED-ka.
