Nau'in nau'ikan sinadaran lantarki ne wanda zai iya fitar da haske ta hanyar wani haske wanda yake hade da abubuwa marasa amfani.Na'urar lantarki, wacce ta bayyana a shekara ta 1962, tana fitar da jan wuta mai karamin haske a kwanakin farko kuma anyi amfani da ita azaman hasken haske bayan HP ta sayi takardar izinin.Kuma daga baya ya inganta wasu nau'ikan nau'ikan nau'ikan. A yau, za su iya fitar da haske a cikin bayyane, infrared da ultraviolet, kuma haskensu ya ƙaru zuwa wani babban matakin.Tare da fitowar farin diode mai haske, amfani ya kasance daga haske mai nuna alama na farko da allon nuni da sauran alamun, a hankali ya bunkasa zuwa amfani da hasken kwanan nan.


Diode mai bada haske (LED) wanda ke gudanar da wutar lantarki ta hanya guda kawai ana kiran sa son rai. Lokacin da wutar lantarki ta gudana ta cikin ta, electrons da ramuka suna haɗuwa a cikin diode don fitar da hasken monochromatic, wanda ake kira electroluminescence. Tsayin nisan da launi na haske ya dogara da nau'ikan semiconductor da aka yi amfani da shi kuma aka ƙara maƙallin da gangan.Yana da fa'idodi na babban inganci, tsawon rai, ba mai sauƙin lalacewa ba, saurin saurin aiki da aminci sama da tushen haske na gargajiya.Hasken haske mai haske na farin LED an inganta a cikin recentan shekarun nan.Kudin da ke cikin lumens dubu, kuma saboda babban adadin saka hannun jari ya kawo farashin ƙasa, amma farashin har yanzu ya fi sauran hasken wutar gargajiya girma.Koyaya, a cikin 'yan shekarun nan an ƙara amfani dashi don dalilai na haske.
