Abstract

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.

Claims

1. A wall lamp with a rotating inner shade, comprising:

a lamp body including a housing having a socket with a base and an open top extending upwardly from the housing to hold a light bulb, the housing including a switch mounted in the housing and partially extending through the housing for a user to selectively turn on the light bulb, and two prongs extending through the housing and adapted to be electrically connected to an electrical outlet;

and two stubs laterally and diametrically extending from the socket near the base;

a shade attached to the housing, the shade being a cylinder with an upper and lower end and including;

an upper cover mounted on the upper end of the shade and having multiple openings radially defined in the upper cover; and

a lower cover mounted on the lower end of the shade, the lower cover being circular, having a center and including a circular groove concentrically defined around the center having a bottom and a vertical outer wall, a locking hole defined around the center within the circular groove having an edge, multiple openings defined in the lower cover around the circular groove, and two arcuate walls extending up from the edge of the locking hole and respectively supporting the stubs on the socket and two gaps formed on diametrically opposite sides of the locking hole between the arcuate walls for the stubs on the socket respectively extending through the gaps;

a stand attached to the lower cover, the stand with a first and second end having the first end bent to form a ring that is securely mounted in the circular groove in the lower cover and a point formed at the second end; and

an inner shade rotatably mounted on the point at the second end of the stand, the inner shade being a cylinder and having an open end facing the lower cover and a closed end, the inner shade including;

a pinhole centrally defined through the closed end of the inner shade, the pinhole in the inner shade having a diameter smaller than that of the stand so that the inner shade is balanced on the point at the second end of the stand;

multiple blades radially formed on the closed end of the inner shade; and

multiple passages defined in the closed end of the inner shade and between adjacent blades on the closed end of the inner shade.

2. The wall lamp as claimed in claim 1, wherein the lower cover further comprises multiple retaining hooks formed on the outer wall of the circular groove extending radially and laterally into the circular groove and a recess formed between the bottom of the circular groove and each retaining hook so that the ring of the stand is received in the recess and snapped between the retaining hooks and the bottom of the circular groove in the lower cover.

3. The wall lamp as claimed in claim 2, wherein the lower cover is screwed onto the lower end of the shade and the upper cover is screwed onto the upper end of the shade.

4. The wall lamp as claimed in claim 1, wherein the stand comprises multiple brackets extending up from the ring of the stand.

5. The wall lamp as claimed in claim 1 further comprising a groove defined around the base of the socket.

6. The wall lamp as claimed in claim 1, wherein the upper cover has a through hole centrally defined in the upper cover (30);

and

the openings are radially defined relative to the through hole in the upper cover.
