The shaderis supported by a holder whichimayz be readily mounted on opaque member 1-: so asrto clear the illuminant 3and; at. -the sametimerso space the. holder from= the shade as; to -aveid any appreciable shadow; V For; this purposecircumferentially spacedsup portsshown asnwiresfi mayextend upwardly from an.'annular. hoops 9. so as to: define a, structure 100 adapted for. sliding. receptionsin cup. i5; with' the hoop 9. preferably adaptedtorestupon an; internal shoulder-10 of. the. cup; and the wiresrfiydi-verging upwardly for yieldable binding; engagement :intthe cup. The holder-is thus receivedin the annular space between the stem of light globe 3 and:.the'sun-. rounding. walllo fcup 5; and above the-reflector 2* the W wires- 8 are bowed outwardlyas; showmat ll-lso. as to clean thev light globe while still; apmtea ciably. radially spacingssaid wires ,from-zcanopy 1-10 6, with the upper ends of the wires then curving inwardly as shown at 12 so as to meet at a washer 13 in alinement with the axis of globe 3 but longitudinally spaced therebeyond.

A standard is mounted on the bowed wires, and is shown as projecting upwardly from washer 13 and adapted to support the shade for the lighting device. As an instance of this arrangement the standard may comprise cooperating rods 14-14a telescopically adjusted by a set screw 25, with an annular hoop 15 at the upper edge of canopy 6 having inwardly projecting arms 16 terminating in a central washer 17 which is. adapted for reception on the rod 14a. The rod 14a may be threaded for reception of a nut 18 on which washer 1'? is adapted to rest so as to support the canopy 6, and the screen '7 may be supported on the arms 16 and washer 17, with a retaining nut 19 threaded onto rod l laior secur ing the parts in assembled relation.

; The shade-is thus adapted for longitudinal adjustmentv with relation to globe 3 by telescopic adjustment of rods 14-14a; and various screen elements -7, as well as various canopies 6, may be readily interchangeably employed in connection with the lighting device. It will also be noted that: the screen element '7 is readily removable with the canopy 6 retaining its operative position; in which event light is reflected and transmitted by the canopy as previously described, while light projected straight upwardly i's non-obstructed and may strike an overlying ceiling for indirect lighting. @If itisdesirable to change the canopy 6 withoutdisturbing the screen '7, the modified construction shown in Fig. 2 may be employed. In this construction screen 37a is fixed relative to a peripheral hoop 200. which has radial arms 16a anda central washer 17a, with the washer adapted for support on rod 140, as previously described; and the hoop 15a of canopy 6a is provided with inwardly projecting lugs 21a adapted to rest upon screen 7a for detachably supporting the canopy.

The invention thus provides extremely simple but practical means for supporting a shade with relation to an illuminant so as to avoid shadows and permit ready adjustment and interchanging of shades; and the invention also provides a supporting means particularly applicable to that type of lighting device in which a reflector underlies aniliuminant with a shade surrounding the illuminant above the reflector so. that'the shade is adapted to create a relatively bright but nonglaring downwardly directed light beyond the periphery of the reflector, together with merely a diiTused light or glow of any desired color emanating in all directions through the shade.
