Akwai dalilai guda uku da ke sa hasken LED yayi duhu
Ya zama ruwan dare cewa hasken wuta na LED zai zama duhu bayan amfani da shi na dogon lokaci. Akwai dalilai guda uku.
Ana buƙatar kwakwalwan kwamfuta na LED don yin aiki a ƙarancin wutar lantarki na DC (ƙasa da 20V), amma wadatar da mu na yau da kullun shine babban ƙarfin AC (AC 220V). Don kunna mains zuwa wutar lantarki da ake buƙata don fitilar, kuna buƙatar na'urar da ake kira "LED constant current drive power."
A ka'ida, idan dai ma'auni na direba sun dace da bead ɗin fitila, ana iya ci gaba da amfani da wutar lantarki kuma a yi amfani da su akai-akai. Abubuwan da ke cikin injin ɗin suna da rikitarwa, kuma kowace na'ura (kamar capacitors, masu gyara, da sauransu) na iya haifar da canji a cikin ƙarfin fitarwa, wanda zai iya sa fitilar ta yi duhu.
Lalacewar tuƙi yana ɗaya daga cikin manyan kurakuran da ke cikin fitilun LED kuma galibi ana iya warware su bayan maye gurbin tuƙi.
LED ya kone
Ita kanta LED ɗin ta ƙunshi bead ɗin fitila ɗaya. Idan daya ko wani bangare nasa ba a kunna ba, to babu makawa zai sanya dukkan kayan aikin ya yi duhu. Gabaɗaya ƙullun fitilun ana haɗa su ne a jere sannan a layi daya - don haka idan wani ƙullun fitila ya ƙone, yana iya haifar da batch na fitilun beads.
Bayan konewa, saman bead ɗin fitilar yana da baƙar fata a bayyane. Nemo shi, yi amfani da waya don haɗa ta zuwa bayan fitilar, gajeriyar kewaya ta, ko maye gurbin ta da sabon bead ɗin fitila.
Daidai ne LED ɗin yana ƙone ɗaya bayan ɗaya. Idan yana ƙone akai-akai, la'akari da matsalar tuƙi - wani bayyanar gazawar drive shine kona fitilun fitila.
Abin da ake kira lalata haske shine cewa hasken hasken yana raguwa da raguwa - wannan yanayin ya fi dacewa a kan fitilu masu haske da masu kyalli.
Fitilar LED ba zai iya guje wa ruɓar haske ba, amma raguwar haskensa yana da ɗan jinkiri, yana da wahala a ga canje-canje da ido tsirara. Duk da haka, ba ya kawar da ƙananan LEDs, ko ƙananan haske, ko kuma saboda dalilai na haƙiƙa kamar rashin ƙarfi na zafi, yana haifar da lalacewa mai sauri na hasken LED.
