Njengohlobo lobugcisa bendawo kawonke-wonke, ngakumbi nangakumbi ufakelo lobugcisa bokukhanya luvela kubomi babantu ukusuka ngaphakathi ukuya ngaphandle ngelixa kwiindidi zokuthetha 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, ukwenzela ukuba ufakelo lokukhanya kobugcisa lube neempawu zobugcisa ezingenakuqhathaniswa kunye nezahlukileyo ezihambelana nezinye iindlela zobugcisa. Ufakelo lokukhanya kobugcisa yindlela yokudibanisa iteknoloji kunye nobugcisa. Iphucula ukukhanya kwendabuko kwaye ibonakalisa ngokugqibeleleyo umphumo wokukhanya kunye nobukrelekrele obubonakalayo.
