Abstract
A lamp assembly for general illumination and/or ornamentation has a base with a support member bearing both a lamp-bulb receiving socket and a lamp shade. The lamp shade, or other ornamental element of the lamp assembly is formed at least in part of an electroluminescent material and, in the disclosed form, the inner surface of the shade is reflective. The lamp assembly, accordingly, includes two sources of illumination, namely the electroluminescent material and a lamp-bulb received in the bulb-receiving socket. A conventional line cord is provided to connect the lamp to any ordinary source of electrical power, and a four-position electrical switch coupled to the line cord permits a user to direct power selectively to the lamp socket, or to the electroluminescent shade, or to both simultaneously. In its fourth position, all electrical power is cut-off so that the lamp is not illuminated.
