     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIGS. 1, 2 and 3, a picture frame and lamp arrangement in accordance with the present invention is generally comprised of a lamp holder 10, a sliding mount 20, a picture frame 30, and a back support 40. 
     The lamp holder 10 comprises two mounting rods 11 aligned at two opposite sides, and two parallel connecting rods 13 respectively and perpendicularly connected to the mounting rods 11 by a respective connector 12. The connecting rods 13 have a respective opposite end respectively connected to the sliding mount 20. The mounting rods 11, the connectors 12 and the connecting rods 13 are respectively made from electrically conductive material through which 12 V low voltage power supply can be transmitted to the lamp holder 10. The mounting rods 11 are respectively pivoted to the connectors 12, therefore the lamp holder 10 can be turned about an axis between the connectors 12. 
     The mount 20 comprises a casing 21, two metal blocks 25, and a back cover 28. The casing 21 comprises a back chamber 22, two opposite side through holes 24 at two opposite lateral sides in communication with the back chamber 22, a top center plug hole 23b at the center of its top side 23, a cap 23c covered on the top center plug hole 23b, two top side plug holes 23a disposed at its top side 23 and equally spaced from the top center plug hole 23b in reversed directions, a bottom wire hole 22a, two opposite side coupling holes 21a bilaterally disposed near its bottom side, and a front coupling groove 21b horizontally disposed at its front side and adapted for coupling to the picture frame 30. The back cover 28 is covered on the back chamber 22 of the casing 21 and fixedly secured thereto by screws 27, having a hanging hole 28a for hanging. The metal blocks 25 are respectively mounted in the side through holes 24 of the casing 21. Each metal block 25 comprises a first screw hole 25a and a second screw hole 25b, a first tightening up screw 25c and a second tightening up screw 25d respectively threaded into the first screw hole 25a and the second screw hole 25b, a plug hole 25e communicating with the first screw hole 25a and aligned with one top side plug hole 23a of the casing 21, and a mounting slot 25f communicating with the second screw hole 25b and adapted to receive one connecting rod 13. The connecting rods 13 have a respective flat rear end respectively inserted through the side through holes 24 of the casing 21 into the mounting slots 25f of the metal blocks 25 and then respectively fixed in place by the second tightening up screws 25d. Two conductors 26 are respectively inserted through the bottom wire hole 22a of the casing 21 into the back chamber 22, and then respectively fastened to the plug holes 25e of the metal blocks 25 by the first tightening up screws 25c. Through the conductors 26, a low voltage power is transmitted from a power source (not shown) to the metal blocks 25, and then transmitted from the metal blocks 25 through the connecting rods 13 and the mounting rods 11 to the lamp holder 10. 
     The picture frame 30 has its top and bottom sides respectively covered with a respective rail 31 for protection. Each rail 31 comprises a coupling groove 32 coupled to the top or bottom side of the picture frame 30, a plurality of screw holes 33 perpendicularly extended to the coupling groove 32, and a plurality of tightening up screws 34 respectively threaded into the screw holes 33 to hold down the picture frame 30 in the coupling groove 32. Further, two end caps 35 are respectively fastened to two opposite ends of each rail 31. The rail 31 which is disposed at the top side has a track 36 to which the front coupling groove 21b of the mount 20 is coupled. 
     The back support 40 is made from a metal wire, having two ends 41 respectively inserted into the side coupling holes 21a of the casing 21 for supporting the mount 20 and the picture frame 30 on for example a table top. When the back support 40 is coupled to the mount 20, is can be turned in the side coupling holes 21a of the casing 21 to adjust the tilting angle of the picture frame 30. When the back support 40 is turned inwards and closely attached to the picture frame 30, the whole assembly can be hung on the wall by the hanging hole 28a of the back cover 28. 
     FIG. 4 shows a second embodiment of the present invention. According to this alternate form, the metal blocks 25 are reversely mounted in the side through holes 24 of the casing 21 of the mount 20, the connecting rods 13 are respectively inserted into the top side plug holes 23a of the casing 21 and then fastened to the mounting slots 25f of the metal blocks 25 by the respective second tightening up screws 25d. 
     FIGS. 5 and 6 show a third embodiment of the present invention. According to this embodiment, the lamp holder 10 is provided with only one connecting rod 13, and the aforesaid metal blocks 25 are eliminated. The connecting rod 13 is an electrically insulative tube having its end fastened to the top center plug hole 23b of the mount 20. The conductors 26 are directly inserted through the connecting rod 13 and connected to the lamp holder 10, and adapted to transmit for example 110 V AC to the lamp holder 10. The lamp holder 10 can be of any type of lamp holder for holding a bulb or lamp tube, or a plurality of bulbs or lamp tubes. 
     FIG. 7 shows a fourth embodiment of the present invention. This embodiment is similar to the aforesaid third embodiment. However, the aforesaid metal blocks 25 are still maintained mounted inside the mount 20. The conductors 26 are respectively fastened to the metal blocks 25. Two electric wires are respectively mounted inside the mount 20 and connected between the metal blocks 25 and the lamp holder 10. 
     FIG. 8 shows a fifth embodiment of the present invention. This embodiment is a wall mount design. According to this embodiment, the aforesaid back support 40 is eliminated, the mount 20 is directly fastened to the wall by screws 42, having a hanger 50 on which the picture frame 30 is hung by a hanging wire 37. 
     It is to be understood that the drawings are designed for purposes of illustration only, and are not intended as a definition of the limits and scope of the invention disclosed, and various modifications and changes could be made thereunto without departing from the spirit and scope of the invention disclosed. For example, the back support 40 can be directly fastened to the picture frame 30; the lamp holder can be a double-head lamp holder for holding two sets of lamps.
