A wall lamp with a rotating inner shade includes a lamp body having a housing and a shade attached to the housing. A stand is attached to the housing within and by means of the shade. An inner shade in balanced on a free end of the stand. The inner shade has a closed upper end and multiple blades formed on the upper end. A passage is defined adjacent blades. Hot air is generated by the burning light bulb and rises in the inner shade. The inner shade rotates when the hot air impinges the blades and passes through the passages. Consequently, the light radiated from the wall lamp is vivid.

1. Field of the Invention
The present invention relates to a wall lamp, and more particularly to a wall lamp with a rotating inner shade.
2. Description of Related Art
FIG. 1 is partially exploded perspective view of a wall lamp in accordance with the present invention;
FIG. 2 is an exploded perspective view of the shade for the wall lamp in FIG. 1;
FIG. 3 is a side plan view in partial section of the wall lamp in FIG. 1;
With reference to the drawings and initially to FIGS. 1 and 2, a wall lamp with a rotating inner shade in accordance with the present invention comprises a lamp body (10), a shade (20) and an inner shade (60). The shade (20) is attached to the lamp body (10). The inner shade (60) is rotatably mounted within the shade (20).
The lamp body (10) includes a housing (12) and a socket (11) extending upwardly from the housing (12). The socket (11) has a base and an open top. A light bulb (13) is electrically mounted in the open top of the socket (11). A switch (14) is mounted in the housing (12) and partially extends through the housing (12) so a user can selectively turn on the light bulb (13). Two prongs (15) are mounted in and extend from the housing (12) and are electrically connected to the switch (14). The two prongs (15) are adapted to be electrically connected to an electrical outlet. A groove (16) is defined around the base of the socket (11) and two stubs (17) laterally and diametrically extend from the socket ( 11) near the base.
The shade (20) is a cylinder. The shade (20) includes an upper end (21) and a lower end (22). An upper cover (30) is mounted on the upper end (21) of the shade (20), and a lower cover (40) is mounted on the lower end (22) of the shade (20). In the preferred embodiment of the present invention, the upper cover (30) and the lower cover (40) are screwed onto the shade (20). A through hole (31) is centrally defined in the upper cover (30), and multiple openings (32) are radially defined in the upper cover (30) relative to the through hole (31) in the upper cover (30). The lower cover (40) is circular, has a center and includes a circular groove (41) and a locking hole (42). The circular groove (41) is concentrically defined around the center of the lower cover (40) and has a bottom (not numbered) and an outer wall (not numbered). The locking hole (42) has an edge and is concentrically defined at the center of the lower cover (40) inside the circular groove (41). Multiple openings (43) are defined in the lower cover (40) around the circular groove (41). Two arcuate walls (44) with an exposed top extend up from the edge of the locking hole (42), and two gaps (441) are formed on diametrically sides of the locking hole (42) between the arcuate walls (44).
