Abstract: A lighting apparatus includes a housing, an electroluminescent quantum dots (QD) unit as a light source, and an electrical component for providing electrical energy to the electroluminescent QD unit. The housing may be in the form of an incandescent bulb, a halogen bulb, a fluorescent tube or a panel. The electroluminescent QD unit includes a plurality of QDs printed on an insulating substrate. The substrate may be flexible so that the electroluminescent QD unit may be bent or curved to conform to the shape of an incandescent bulb, fluorescent tube or panel or a halogen filament so as to mimic these traditional light sources. Methods for retrofitting traditional or LED light fixtures with a lighting apparatus including an electroluminescent quantum dots (QD) unit as a light source are also described.
