## Abstract

The object of the invention is to provide an improved orbital lamp with easy, inexpensive and safe installation comprising one top lid having one semi-circled opening on its back in corresponding to the opening on the lid top on the bottom lid. Said top lid has one L-shaped opening on its top extending to its side for the moving rod to move therein. Said top lid has one arc-shaped protrusion block on its front end. Said movable pivot has two protrusion rings with proper distance in the between to be set into the opening on the supporting plate on the bottom lid. Said movable pivot has one inlaid fastening plate stretching out of the lid top on the bottom lid to inlay into the moving trough on the orbital strip through the movement of the moving rod. The flat long strip protruded poles on the bottom lid may fit into the the through holes on the top lid making the connection of the top lid and the bottom lid tight and firm. The two protruded beads on the diameter of the top board on the supporting pivot connected to the end of the lamp shade may slide into the two shallow indentations on the arc-shaped protrusion block having one through hole for the top board to pass through for fastening the lamp fixture.

## Claims

### Claim 1

An orbital lamp comprising:
a top lid, a movable pivot, a bottom lid, a lamp fixture, a lamp body, and an orbital strip, wherein said lamp body includes contact terminals that are received in internal receptacles of said lamp fixture, said orbital strip includes a slot in a central area thereof, said slot includes a pair of electrically conductive strips therein;
said top lid includes a semi-circular opening on a rear side thereof which corresponds in location to a semi-circular opening on a rear side of said bottom lid, said top lid further includes an opening to receive a moving rod of said movable pivot, said top lid further includes a protrusion block with a through hole therein, and said top lid includes openings to receive protruding poles of said bottom lid, said bottom lid includes a supporting plate with a semi-circular opening on a top side thereof;
said movable pivot has a pair of electrically conductive slices and a pair of fastening plates, said movable pivot includes two protrusion rings spaced so as to fix said movable pivot in position on said supporting plate, said moving rod is affixed to said movable pivot, said movable pivot further includes an inlaid fastening plate on a rear end of said movable pivot, said inlaid fastening plate is inserted into said slot on said orbital strip, said movable pivot is rotated by said moving rod to affix said inlaid fastening plate in said slot of said orbital strip.

### Claim 2 (depends on 1)

The orbital lamp of claim 1 wherein:
said lamp fixture includes an attaching fixture on a rear end thereof, said top board includes protrusions thereon, said protrusions are received in indentations on an inner surface of said protrusion block when said attaching fixture in inserted into said through hole of said protrusion block and said lamp fixture is rotated.

### Claim 3 (depends on 1)

The orbital lamp of claim 1 wherein:
said protruding poles of said bottom lid are slanted and said openings of said top lid are slanted to correspond to said protruding poles, and
said top lid includes a plurality of side through holes and said bottom lid includes a corresponding number of inverse hook bodies such that each of said inverse hook bodies is received in a corresponding one of said side through holes so that said top lid is separated from said bottom lid by pressing downward on an I-shaped pressing block on said top lid.
