Lam-cup structure

The utility model discloses a lam-cup structure, which is the improvement of an existing lamp-cup. A straight copper sheet is arranged in a vertical groove in the lamp-cup; one convex spring sheet connected with the screw of an outer pipe of the lower part of a light bulb is arranged on the upper part of the straight copper sheet, or two convex rids are arranged on the spring piece of the straight copper sheet, for clamping the bottom diameter of the outer screw of the lower part of the light bulb; thereby, the conductive function can be increased. The structure thereof is simple; the utility model overcomes the disadvantages of scintillation or short circuit caused by point contact heat generation in the prior art.
