The disclosure relates to a lamp socket, and more specifically to a lamp socket so configured as to restrict the insertion of bulbs other than the intended bulb, by arranging ribs on the socket housing corresponding to the shape of a key formed on the bulb. The lamp socket of the disclosure is configured so that when the base of a bulb is inserted into the receiving space of the socket housing, the key formed on the base is not interfered with by the ribs arranged in the receiving space, while if the shape of the key does not match the pattern in which the ribs are arranged, the key will be caught on the ribs, preventing the insertion of the base.
