Yadda za a yi amfani da multimeter don gano lalacewar LED Bead?
Fitilar fitilun LED yawanci tana ɗaukar jeri da haɗin layi ɗaya. Lokacin da fitilar fitilar LED ta lalace, siffa ta musamman na kuskure ita ce hasken bai isa ba. Don lalacewar fitilar fitilar LED a jere da layi ɗaya, ana iya amfani da hanyoyi masu zuwa don ganowa.
Yi la'akari da ko yana da kyau ko mara kyau:
(1) Gano Multimeter da hanyar hukunci. Tun da bead ɗin fitilar LED yana da halayen diode, ana iya gano shi ko yanke hukunci ta amfani da toshe diode na dijital na multimeter ko nau'in nau'in multimeter R × 1 block a cikin hanya ko buɗe kewaye. Idan babu matsala tare da bead ɗin fitilar LED, bead ɗin fitilar LED zai haskaka lokacin ganowa. Idan fitilar fitilar LED da aka gano ba ta da sifofin diode kuma ba za ta fitar da hasken tauraro kaɗan ba, za a yanke hukuncin lalacewa.
(2) Hanyar hukunci daidai gwargwado. Ga wasu tsofaffin beads fitilu na LED, amfani da gano multimeter sau da yawa na iya ganin hasken micro-tauraro, amma har yanzu bai isa haske ba bayan kunnawa. Dangane da wannan, ana iya amfani da hanyar layi ɗaya don nemo beads ɗin fitilar LED masu tsufa. Ɗauki kwan fitila 3W a matsayin misali. Takamammen hanyar ita ce kamar haka.
(3) Hanyar ƙayyade daidaitaccen LED. Yin amfani da LED 1W mai aiki da kyau, kowane fil ana sayar da shi da gajeriyar waya a matsayin fitilar ganowa, sannan a yi amfani da shi don gajeriyar kewaya kowane katakon fitilar LED a cikin kwan fitila. Da zarar an gajarta shi zuwa fitilar fitilar LED, 3W Hasken kwan fitila zai karu sosai, kuma fitilar LED da aka gajarta ita ce tsohuwar fitilar fitilar LED. Bayan maye gurbin sabon, za a iya kawar da kuskuren.
(4) Hanyar gajeriyar waya. Idan babu irin wannan LED mai kyau a halin yanzu, Hakanan zaka iya amfani da gajeriyar ƙarshen gajeriyar waya don kewaya kowane kwan fitila na LED a cikin kwan fitila. Da zarar an gajarta shi zuwa wani kwan fitila na LED, hasken fitilar 3W zai ƙaru sosai. Fitilar fitilar LED da aka gajarta ita ce tsohuwar fitilar fitilar LED. Bayan maye gurbin sabon, za a iya kawar da kuskuren. Idan babu sabon na'ura mai canzawa a lokaci guda, Hakanan zaka iya ɗan gajeren kewaya da katakon fitilar fitilar LED a ƙarshen duka. Da zarar kun sayi sabon kayan haɗi, yakamata ku maye gurbinsa cikin lokaci.
