Viwoneskero vya LED ni mtundu uphya wa chipangizo cha magesi chakuwoneskera ivyo vikupangika na kuŵika ungweru-emitting diodes (LEDs) mu ndondomeko. Chifukwa chakuti vikuŵala chomene, vikuwoneka makora chomene, ndiposo vikukhala nyengo yitali, ŵanthu ŵakuvigwiliskira ntchito chomene pa vinthu nga ni vithuzithuzi vyakusaska vya kuwaro.
Kugwiriskira ncito magesi gha LED pakuŵala kuzamunjira dankha mu malo gha mababu gha incandescent agho ghakugwiriskira ncito nkhongono-, ndipo pamanyuma pake pachokopachoko kuzamunjira mu msika wose wa magesi, ndipo kuzamuponoska magesi ghanandi. Sonosono apa, ma LED ghatuŵa ghakwaniska kugwiliskira nchito nkhongono za chip yimoza - zakujumpha 1 watt ndiposo ungweru uwo ukufumira mu 25 lumens, ndipo ivi vikupangiska kuti ŵaŵe ŵakugwira ntchito chomene.
