Waa maxay Farqiga u dhexeeya LED-ka iyo Luminescence tooska ah

Isha nalka LED-ka ee balastar dhinaca nalka ah waa nalka dambe ee ka samaysan xariiq-qaabeeya ama dhibic-qaabeeya ilaha iftiinka ee dhinaca dhinaca saxanka hagaha iftiinka gaarka ah. Habka iftiinka dambe ee tooska ah waa mid fudud. Uma baahna looxa hagaha iftiinka. Waa in la dhigo isha iftiinka (LED chip array) iyo PCB xagga hoose ee iftiinka dambe. Ka dib marka nalka laga toogto LED-ka Xuubku wuxuu u soo baxaa si isku mid ah. Jawaab Kordhinta: Marka isha laydhka ee LED lagu dabaqo cabbir weyn oo LCD ah, miisaanka iyo kharashka guddiga hagaha iftiinka ayaa la kordhin doona cabbirka, iftiinka iftiinka iyo labbiska ma noqon doono mid ku habboon. Isla mar ahaantaana Sababtoo ah TV-yada LCD ma gaari karaan kantaroolka firfircoon ee gobolka ee LCD TV-yada, waxay gaari karaan oo kaliya hal-qaabaynta iftiinka iftiinka, halka waxqabadka iftiinka tooska ah ee LED uu ka fiican yahay. Waxay gaari kartaa xakamaynta firfircoonida gobolka ee LCD TV. Iftiinka dambe ee iftiinka wuxuu noqon karaa mid aad u khafiif ah, laakiin heerka isticmaalka iftiinka ee isha dambe waa mid yar, iyo heerka khafiifka ah ee isticmaalka, waa yaraanta heerka isticmaalka. Xuddunta tignoolajiyadadeedu waa naqshadeynta iyo soosaarka guddiga hagaha iftiinka. Waqtigan xaadirka ah, waxaa jira laba nooc oo daabacaadda iyo toogashada qaababka samaynta. Qaabka looxa hagaha iftiinka, kuwa kale sida toogashada oo lagu daray daabacaadda, dhibcaha laysarka, daxalka, iwm, kuma habboona mabaadi'da wax-soo-saarka dufcadda. Faa'iidooyinka tignoolajiyada tooska ah ee tooska ah ayaa ah heer sare -profile, xagal daawasho wanaagsan, waxtarka isticmaalka iftiinka sare, qaabdhismeedka fudud, iwm. Meel gaar ah u hay inta u dhaxaysa faafiyaha iyo isha iftiinka LED si loo hagaajiyo isku-duubnaanta dhalaalka. Sidaa darteed, iftiinka dambe ee tooska ah wuxuu sidoo kale kordhiyaa dhumucda, miisaanka, iyo isticmaalka awoodda moduleka. Sidaa darteed iftiinka dambe ee iftiinka.
