Njengohlobo lobugcisa bendawo yoluntu, ngakumbi nangakumbi ufakelo lokukhanya kobugcisa luvela kubomi babantu ukusukangaphakathiukuya ngaphandle ngelixa kwiindidi zentetho kunye nezinto. Olu fakelo lunokufumaneka kwindawo yorhwebo, indawo yokhenketho lwenkcubeko nokhenketho ebusuku, iidolophu ezineempawu kunye nezinye eziyeyona nto inomtsalane apho.
Ihluke kwisixhobo sokukhanya esiqhelekileyo esidlala indima enkulu yokukhanyisa indawo, ukufakwa kobugcisa bokukhanya kudibanise ubugcisa bokukhanya kunye nomfanekiso oqingqiweyo kunye nokudalwa kobuhle besandi, ukukhanya kunye nombane. Ukukhanya kuneempawu ezintathu eziphambili zokuqina, umbala kunye nomoya, ukuze ubugcisaufakelo ukukhanyazineempawu zobugcisa ezingenakuthelekiswa nanto xa zithelekiswa nezinye iindlela zobugcisa. Ukufakwa kokukhanya kobugcisa yindlela yokudibanisa iteknoloji kunye nobugcisa. Iphucula ukukhanya kwendabuko kwaye ibonakalisa ngokugqibeleleyo umphumo wokukhanya kunye nobukrelekrele obubonakalayo.
