Wani al'amari ne na yau da kullun cewa hasken wuta ya zama duhu da duhu yayin da ake amfani da su. Takaitacciyar dalilan da zasu iya duhuntaHasken LED, wanda bai wuce wadannan abubuwa guda uku ba.

1.Drive ya lalace

Ana buƙatar beads ɗin fitilar LED don yin aiki a ƙaramin ƙarfin DC (kasa da 20V), amma ikon mu na yau da kullun shine babban ƙarfin AC (AC 220V). Don kunna wutar lantarki zuwa wutar da fitilun beads ke buƙata, muna buƙatar na'urar da ake kira "LED constant current tuki wutar lantarki".

A bisa ka'ida, idan dai ma'aunin direba ya dace da farantin ƙwanƙwasa fitila, ana iya ci gaba da kunna shi kuma ana amfani da shi akai-akai. Ciki na direba yana da rikitarwa. Rashin gazawar kowace na'ura (kamar capacitor, rectifier, da sauransu) na iya haifar da canjin wutar lantarki, sannan kuma ya sa fitilar ta dushe.

Lalacewar direba shine mafi yawan laifin da ke cikin fitilun LED. Yawancin lokaci ana iya warware shi bayan maye gurbin direba.

2.Leda ya kone

Ita kanta LED ɗin ta ƙunshi beads ɗin fitila ɗaya bayan ɗaya. Idan daya ko sashinsu ba a kunne ba, to lallai ne ya duhuntar da dukkan fitilar. Yawancin beads ɗin fitilu ana haɗa su a jere sannan a layi daya - don haka idan an kona kullin fitilar, rukunin fitilun ba zai iya haskakawa ba.

Akwai baƙaƙen baƙaƙen aibobi a saman kullin fitilar da aka kone. Nemo shi, haɗa shi zuwa baya tare da waya da gajeren kewaya shi; Ko kuma sabon bead ɗin fitila zai iya magance matsalar.

Led lokaci-lokaci yana ƙone ɗaya, yana iya zama kwatsam. Idan kun ƙone akai-akai, ya kamata ku yi la'akari da matsalar tuƙi - wata alama ta gazawar tuƙi ita ce ƙone bead ɗin fitila.

3. LED haske attenuation

Abin da ake kira lalata haske shine cewa hasken hasken yana raguwa da ƙasa - wanda ya fi dacewa a cikin fitilu masu haske da masu kyalli.

Fitilar LED ba za ta iya guje wa ruɓar haske ba, amma saurin ruɓewar haskensa yana da ɗan jinkiri, kuma yana da wahala a ga canjin da ido tsirara. Duk da haka, baya yanke hukuncin cewa ƙananan LED mai inganci, ko farantin haske mai ƙarancin inganci, ko kuma saboda dalilai na haƙiƙa kamar rashin ƙarancin zafi, saurin lalata hasken LED yana sauri.
