A 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 having an insertion hole at its front surface and a conductive plate. 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, or rotation space, is formed between the first space and the bottom surface. 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.

Lamp socket

A lighting apparatus includes an apparatus body for supporting an LED lamp having an earth cap, an earth socket to which the earth cap of the LED lamp is mounted, and an attachment base provided in the apparatus body, the earth socket being attached to the attachment base. The earth socket includes a conductor plate for mechanically holding a lamp pin of the earth cap, the conductor plate being electrically connected to the lamp pin. The attachment base and the earth socket include a connecting unit for earth-connecting the conductor plate of the earth socket and the apparatus body.
