Dole ne -duba: Ilimin Ilimin Ƙarfin Direban LED

Rushewar zafi, ikon tuƙi, da maɓuɓɓugar haske sune mafi mahimmancin sassan ingantaccen hasken LED. Ko da yake zafi yana da mahimmanci musamman, tasirin zafi yana tasiri kai tsaye ga ingancin rayuwar samfuran hasken wuta, amma tushen hasken shine ainihin ɓangaren samfurin gaba ɗaya. Zaman lafiyar rayuwa da fitarwa na halin yanzu da ƙarfin lantarki na wutar lantarki da kansa yana da tasiri mai girma akan rayuwar rayuwar samfurin gaba ɗaya. Samfurin wutar lantarki na LED shima samfurin ne mai goyan baya. A halin yanzu, ingancin wutar lantarki a kasuwa bai yi daidai ba. Abubuwan da ke biyowa suna ba da wasu ilimin da suka danganci ikon direban LED. 1. Menene ma'aunin wutar lantarki na LED Driver mai samar da wutar lantarki yana canza wutar lantarki zuwa takamaiman ƙarfin lantarki don fitar da hasken wutar lantarki na LED. Yawancin lokaci: shigar da wutar lantarki ta LED ya haɗa da babban ƙarfin wutar lantarki AC (wato ikon birni), ƙarancin wutar lantarki DC DC , High-voltage DC, low-voltage da high-frequency AC (kamar fitarwa na masu canji na lantarki), da dai sauransu. Fitar da wutar lantarki ta LED ɗin shine mafi yawan madaidaicin tushen yanzu wanda zai iya canza ƙarfin lantarki tare da canje-canjen rage ƙimar ƙimar wutar gaba ta LED. Mahimman abubuwan da aka haɗa na samar da wutar lantarki na LED sun haɗa da mai sarrafa sauyawa, ƙaddamarwa, bangaren canzawa (MOSFET), juriya na amsawa, na'urar tace bayanai, na'urar tace fitarwa, da sauransu. Dangane da buƙatun lokuta daban-daban, dole ne a sami da'irori na kariyar overvoltage, shigarwar -rashin kariyar kariyar, kariyar buɗe titin LED, kariya ta wuce gona da iri da sauran hanyoyin. 2. Siffofin samar da wutar lantarki na LED (1) Babban aminci yana da kama da ikon direba na fitilun titin LED, wanda aka sanya shi a tsayi mai tsayi, bai dace da kulawa ba, kuma farashin kulawa yana da girma. (2) Babban ingancin LED shine samfurin ceton makamashi, kuma ingancin ƙarfin tuƙi yana da girma. Yana da matukar muhimmanci ga zafin zafi na wutar lantarki a cikin fitilar. Ingancin wutar lantarki yana da yawa, asararsa kaɗan ne, kuma zafi a cikin fitilar zai zama ƙarami, wanda zai rage zafin fitilun. Yana da amfani don jinkirta gazawar haske na LED. (3) Abubuwan da ke da ƙarfi da ƙarfin wutar lantarki sune abubuwan da ake buƙata na nauyin grid na grid. Gabaɗaya, na'urorin lantarki da ke ƙasa da 70 watts, babu alamun dole. Ko da yake abubuwa guda ɗaya na wutar lantarki tare da ƙananan wutar lantarki, ƙananan ƙarancin wutar lantarki ba su da tasiri a kan wutar lantarki, yin amfani da hasken wuta da dare, nau'in nau'in nau'in nau'in nau'in nau'in nau'i yana da hankali sosai, zai haifar da mummunar gurɓataccen gurɓataccen wutar lantarki. Don ikon direban LED na 30 watts 40 watts, an ce nan gaba kadan, ana iya samun wasu alamomin abubuwan wutar lantarki. (4) Akwai nau'ikan hanyoyin tuki guda biyu a yanzu: ɗaya shine tushen wutar lantarki akai-akai don maɓuɓɓugar ruwa akai-akai, da kowane tushen tushen tushen yanzu ga kowane LED daban. Ta wannan hanyar, haɗin yana da sauƙi, rashin nasarar LED duk hanya, ba ya shafar aikin sauran LEDs, amma farashin zai zama dan kadan mafi girma.

Amfaninsa shi ne cewa farashin yana da ƙasa, amma sassauci ba shi da kyau, kuma wajibi ne don magance matsalar wani rashin ƙarfi na LED, wanda ba zai shafi aikin sauran ayyukan LED ba. Waɗannan siffofi guda biyu suna zama tare na ɗan lokaci. Multi-Lu Hengliu fitarwa hanyoyin samar da wutar lantarki zai zama mafi kyau dangane da farashi da aiki. Wataƙila shi ne babban alkibla a nan gaba. (5) Da ikon kare LED kariya na LEDs ne in mun gwada da matalauta, musamman anti-reverse ƙarfin lantarki. Ƙarfafa kariya a wannan yanki kuma yana da mahimmanci. Ana shigar da wasu fitilun LED a waje, kamar fitilun titin LED. Sakamakon bude wutar lantarki da shigar da walƙiya, tsarin grid zai mamaye raƙuman ruwa daban-daban, kuma wasu raƙuman ruwa suna haifar da lalacewar LED. Saboda haka, bincika “Zhongke Huibao “Ya kamata a rasa ikon direba a cikin kariyar hawan igiyar ruwa.
