LAMP SOCKET

The lamp socket receives an LED lamp provided with an L-shaped pin having a contact piece and an extension piece extending from a tip of the contact piece. The lamp socket includes a socket body provided with an insertion hole at its front surface and a conductive plate formed into an approximate band plate shape and placed inside the socket body to face the insertion hole. The conductive plate has one surface facing an axis of the insertion hole and a first space is formed between the other surface of the conductive plate and an inner surface of the socket body. A second space is formed between a bottom surface of the socket body and the conductive plate. A third space is formed between the first space and the bottom surface, and forms a rotation space together with the second space. When the pin is inserted via the insertion hole and the LED lamp is rotated, the contact piece comes in contact with the conductive plate and the extension piece passes through the rotation space.
