The invention provides a lamp screw cap (200) comprising a thread structure (220), wherein the thread structure (220) comprises repetitive elements (225) defining tops (230), valleys (240), and a central plane (250), wherein tops (230) protrude relative to the central plane (250) and wherein the valleys (240) are recessed relative to the central plane (250), wherein: for a plurality of tops (230) applies that each top (230) comprises a first top segment (231), a second top segment (232), and a middle top segment (233), together defining the top (230), wherein the middle top segment (233) is configured most remote from the central plane (250); for a plurality of valleys (240) applies that each valley (240) comprises a first valley segment (241), a second valley segment (242), and a middle valley segment (243), together defining the valley (240), wherein the middle valley segment (243) is configured most remote from the central plane (250); the first top segment (231), the second top segment (232), the first valley segment (241), and the second valley segment (242), have the same first curvature; one or more of the following applies: the plurality of tops (230) have a protruding part (235) protruding relative to the first curvature in a direction away from the central plane (250); and the plurality of valleys (240) have a shallow part (245) receding relative to the first curvature in a direction to the central plane (250).

A light bulb holder structure and a light bulb having same, in which the bulb cap of the light bulb holder is provided with a plurality of grooves in a tactful manner, and the depth of the grooves is greater than that of the external threads of the bulb cap, such that after the bulb cap is mounted on the light bulb and the light bulb is mounted on the light socket, the water accumulated between the light bulb holder structure and the light socket can be effectively discharged through the grooves. As a result, failure of the insulator (connector) on the light bulb holder structure caused by water accumulation can be avoided to a certain extent, thereby improving the reliability and safety of the light bulb.

The present disclosure discloses a novel lamp holder structure. A lamp holder shell of the novel lamp holder structure comprises a shell main body and a lamp holder top cover arranged at the upper end of the shell main body, a bulb installation hole is formed in the shell main body, a main body installation part located above the bulb installation hole is arranged at the upper end of the shell main body, a wire placing groove is formed in the middle of the main body installation part, a top cover wire pressing part is arranged in the middle of the lamp holder top cover. By means of the structural design, the present disclosure has the advantages of being novel in design, simple in structure and convenient and fast to wire.
