Daiode i bvisaho tshedza

Diode ine ya bvisa tshedza ( LED ) ndi tshaka ya eḽekiṱhironiki ine ya shumisa semiconductor u itela u bvisa tshedza musi muḓagasi u tshi fhira khatsho. Eḽekiṱhironi kha semiconductor dzi ṱangana hafhu na mabuli a eḽekiṱhironi, ngauralo dza bvisa Manda nga tshivhumbeo tsha dziphothoni , Muvhala wa tshedza (u tshimbilelanaho na maanḓa a dziphothoni) u vha nga maanḓa ane a ṱoḓea uri dzielekitironiki dzi kone u pfuka tshikhala tsha band ya semiconductor .  Tshedza tshitshena tshi wanala nga u shumisa zwithu zwinzhi zwine zwa bvisa tshedza kana leyara ya phosphor ine ya bvisa tshedza kha tshishumiswa tsha zwithu zwine zwa bvisa tshedza. 

U bvelela sa zwipiḓa zwa eḽekiṱhironiki zwi shumaho nga 1962, dzi- LED dza u thoma dzo vha dzi tshi bvisa tshedza tsha fhasi tsha infrared (IR).  Infrared LED dzi shumiswa kha sekhethe dza u langa zwithu zwi re kule, u fana na dzine dza shumiswa na zwishumiswa zwo fhambananaho zwa eḽekiṱhironiki zwa vharengi. mavhone a dza u thoma dzine dza vhonala tshedza dzo vha dzi na vhuhali ha fhasi nahone dzo vha dzi tshi tou vha na muvhala mutswuku.

LED dza kale dzo vha dzi tshi shumiswa sa mavhone a u vhonetshela ,dzi tshi dzhiela vhudzulo mavhone  matuku a are na vhuhali vhudzhi, na kha zwiṱirathedzhi zwa zwipiḓa zwa sumbe , Mveledziso dza nga murahu dzo bveledza dzi  LED dzine dza wanala nga vhulapfu ha tshedza tshi vhonalaho, tsha ultraviolet (UV), na tsha infrared tshine tsha bvisa tshedza tshihulwane, tsha fhasi, kana tsha vhukati; sa tsumbo, dzi LED tshena dzo teaho u vhonetshela lufherani na nnḓa. LED dzo dovha dza bveledza tshaka ntswa dza zwishumiswa zwa u sumbedza na sentsara, ngeno zwikalo zwadzo zwa nṱha zwa u tshintsha zwi tshi shumiswa kha thekinoḽodzhi ya vhudavhidzani ya mvelaphanḓa . LEDs dzo shumiswa kha zwithu zwo fhambanaho u fana na u vhonetshela ha vhuendedzi , mavhone a fairy, mavhone a strip, mavhone a ṱhoho a goloi, u ḓivhadza, mavhone a tshiṱeidzhi, mavhone a tshiofisi, zwiga zwa vhuendi, dzi flash dza khamera, wallpaper yo vhonetshelaho, mavhone a u hula a horticultural, na devices dza zwa ngalafho. 

LED dzi na zwivhuya zwinzhi u fhira zwipida zwa tshedza zwa incandescent, zwi katelaho u shumisa maanḓa a fhasi, vhutshilo vhudzhi, u khwaṱha ha muvhili ho khwinifhazwaho, vhuhulwane vhuṱuku, na u ṱavhanya u shanduka. U itela u tshintshana na phanele idzi dzine dza vha dzavhuḓi nga u angaredza, zwithu zwi si zwavhuḓi zwa dzi LED zwi katela mikano ya muḓagasi kha mutsiko wa fhasi na nga u angaredza kha maanḓa a DC (hu si AC ), u sa kona u ṋetshedza tshedza tsho linganelaho u bva kha DC ine ya khou ṱhavha kana fhethu ha ṋetshedzo ya muḓagasi ya AC, na mutsho wa fhasi na wa nṱhesa wa u shuma na mutsho  wa u vhulunga.
