The hollow base and annular top portion 7 of the base provide a central opening through which suitable insulated electric wires 11 extend, one end of each of said wires being connected with the lamp socket 8 in the usual manner, and the opposite ends being connected with the line or source of electric supply which may be of any ordinary and well known or desired form.

Suitable light-producing oremittingmeans is provided, which, in the form shown in the accompanying drawings, comprises, by preference, an incandescent electric lamp bulb 12 adapted to be mounted in the socket 8 and connected with the source of electric supply by means of the wires 11, or equivalent lighting means.

An outer light-enclosing member or case 13, which, by preference, comprises a globe formed of translucent glass having an annular bottom rim mounted in the flanged base 1, and an annular flanged top rim on the upper open end of the glob-e, which is covered by a top outer hood or canopy 1 1, which is, by preference, formed of the same or similar suitable translucent material and has a bottom annular peripheral flange 15, is provided and mounted in position to surround and enclose the light-producing means and light. The annular bottom flange 15 of the canopy surrounds the fianged top rim of the globe member 13 on which the cover or canopy is supported.

Suitable light-coloring means is provided which, by preference, comprises a colored light screen 16 formed of translucent or transparent colored glass, and mounted inside of the outer translucent case or globe in position to cover and surround or cover or surround the light-producing means and light within the globe, or to extend between the light-producing means and translucent case or globe, so as to color the rays of light produced within the latter and cause the translucent case or globe member to be colored and illuminated and caused to glow with any desired color or colors thus imparted by the colored rays of light produced and colored within and caused to pass outward through and to radiate from the translucent globe or case, for coloring and illuminating the same and surrounding objects.

In the form of lamp shown in Fig. 1 of the accompanying drawings, the light-coloring means or light screen 16 comprises a cylindrical main body portion formed in two substantially semi-cylindrical sections 17 and 18 of colored glass secured together by means of upright angular double flanged metallic strips 19 which are Z-shaped in cross section and interposed between the adjacent straight upright edges of said semi-cylindrical glass sections, so that the outer upright flange of each of said strips overlaps the adjacent margin of one of said glass sections and the inner flange of each. of said angular strips overlaps the inner margin of the other one of said glass sections; both of said semi-cylindrical sections being bound together by a plurality of wire binding rings 20 which an seated in circumferential grooves formed between circumferential beads 21 on the peripheral surfaces of said sections 17 and 18. The wire binding rings are adapted to be tightened by twisting the ends of the wires forming each ring together; and the sections thus secured together form a cylinder or light-screen of colored glass, the bottom end of which is seated in the upper open flanged end or rim of an annular collar 22 the bottom peripherally flanged end of which fits over the annular upper shoulder 5 on the base top 7, and the upper flanged rim of which surrounds the bottom edge of said cylindrical colored lightscreen 16. (See Fig. 1.)

an inner color hood .8, formed of trans lucent or transparent colored glass of any desired color, is mounted on the inside of the outer translucent case or globe 13 in position to cover the light-producing means or electric lamp bulb, or to extend between the latter and the outer translucent globe 13 or canopy ll, or any desired part of the translucent 1i ght-enclosing outer case or globe, for coloring and illuminating the same by coloring the light which emanates from within and passes through the light-coloring means or light-screen formed by said colored hood and through said translucent outer light-enclosing member or case. The hood 28 may be used in connection with the cylindrical light-coloring screen comprising the connected colored glass sections 17 and 18, as shown in Fig. 1, or independently and without said sections or cylindrical color screen, as shown in Fig. 5, in which the outer light-enclosing globe or case including the globe 13 and canopy 14 of translucent glass are identically the same as shown in Fig. 1.

In Fig. 1, however, the hood member 23 of the colored glass light screen or lightcoloring means 16 is supported on the cylindrical light screen formed by the colored glass sections 17 and 18 to which said hood member is removably attached.

A tapered truncated-cone shaped annular collar 24, formed of sheet metal and having a depending outer circumferential flange 25 on its upper rim adapted to encircle and overlap the upper end margins of the connected light- screen sections 17 and 18, and having an inwardly projecting annular bot-- tom hoodsupporting flange 9.6 on the relatively small bottom annular rim and adapted to extend under the bottom annular rim of the inverted cup-shaped hood 28, is adapted .a-tageaagiee 3 to support said hood on: the -icylindri-culur iaine: 'chahgging the outer translucent; light-enclosbody portion ofthe coloredglassdight-screen ingscase orglobeawAny-deslred color or the light-coloring: means orJ-light-screena -co1ored light- screen sections 17 and 18 and F and form: a connection betweensaid'parts of The glass hood 23 is of smaller. diameterthan' the cylinder formed of the I twoueon'nected the tapered truncated-coneshapedbody por 1 tion of the 'collar 245 extends upward-and.-
