concise, and exact description, reference being had to the accompanying drawings, Y'

forminga part of this speciication. Y The present invention relatesbroadly to illumination and more particularly `to light supports.

for the lamp carrying element whereby an electric conductor or yconductors maybe ca'rs' i'ied-in the support without danger of becoming injured when the support is adjusted in various positions.

Other objects ofmy 'invention not hereinbeforepointed'out will appear from the following detailedY description and the claims,

taken with an inspection of the accompany- 30 v ing drawings, in which- Figure 1 is a perspective view ofa lightV support embodying the improvements of myV invention; e

Fig. 2 is an enlarged vertical sectional view of the supporting bracket andy lamp carrying member; and e f Fig. 3 is a transverse sectional view of the saine.

vReferring more particularly to the drawings, wherein similar characters ofreference designate like and corresponding parts throughout the variousviews, 10 designates they supporting bracket which yconsists'of a channel portion 11 having end ywalls 12 pro'- vid'ed with concentric openings' 18.
