A lamp socket having a double-deck center contact strip includes a socket body having an inner hollow provided with a metal threaded sleeve for receiving a lamp. The socket body is provided inside with a curve-shaped center contact strip having one side fixed on the socket body, and the other side turning upward and located in the center of the threaded sleeve but separating from the threaded sleeve. The double-deck center contact strip is composed of a copper and a steel contact strip, the copper contact strip located on top for contacting with the contact under a lamp and conducting elasticity, while the steel contact strip positioned under the copper contact strip for reinforcing the elasticity of the center contact strip, thus maintaining good contact between the lamp socket and the lamp for conducting electricity well, prolonging service life and ensuring safety.
