Claims

[Scope of utility model registration request]

The invented ring is a ring-shaped one made of aluminum, with an outer diameter of 25.8 mm and two helical threads cut, and an inner diameter of 14 mm with two helical threads cut out like the outside. The ring is 6mm thick. This ring is made to match the threaded portion of the body of the light bulb socket, and the inner thread of the ring is made to match the threaded part of the light bulb.
