More specifically theinvenlower plate 8 is preferably made'of aimaterial tion comprises an electric lamp provided with a adapted-to take a fine finish such as wood, or a 5;. multiplicity of light-radiating surfaces at a di.s-' resin, that. the socket 2 in fact seats directly. 5 Z

While most of the 55 light which is given off at the outer extremities of the legs 5 will have come directly to the legs from the light bulb I a part thereof at least will be light reflected by the bulb-enclosing shade 11.

Instead of tinting the .legs 5 of the lamp to various colors in order to give oiT light of a desired shade at their lower ends the legs themselves may be uncolored and there may be provided a colored disc or filter at the end of the leg adjacent the light source. In Figure 2 a disc or filter 2i is illustrated at the upper end of one of the legs 5. If desired such filters can be provided on all the legs in the same color, in different colors, or may be omitted entirely.

I claim:

1. In an electric lamp comprising an electric light source and a base supporting said source, said base including a plurality of supporting elements each having an end exposed to said source and having the characteristic of transmitting and bending light without emitting same between its ends, the ends of said elements spaced from said source facing outwardly to emit light received from said source, spaced horizontal elements spacing said supporting elements, a conductor conduit extended between said horizontal elements, a connection at the upper end of said conduit to seat removably said light source, a current conductor extended upwardly thru said conduit to said connection, and a shade encloselements being spaced from said light source to emit colored light.

3. An electric lamp comprising an electric light radiating source and a base supporting said source above a supporting surface, said base including a plurality of supporting legs arranged in a circle and exposed at their upper ends to light rays from said source, said legs being formed of a material having the characteristic of transmitting light from one of its ends to the other without emitting light between said ends, the lower portions of said legs being turned outwardly and upwardly to form surface-contacting feet, and the lower ends of said legs being directed outwardly to provide a plurality of spaced secondary sources of light at the base of said lamp.
