Abstract
A lamp holder includes a contact plate having an end in a curved shape, and the other end fixed onto a side of an insulating base by an end of a first fixing element, such that a predetermined distance is formed between the end of the contact plate and the insulating base. The first fixing element is passed through the insulating base, and the other end thereof is outside the other side of the insulating base for coupling an anode wiring element. A thread is formed inside a contact socket, and an extended portion is extended from the bottom side of the contact socket and fixed onto the insulating base by a second fixing element, and the second fixing element is passed through the insulating base, and the other end thereof is outside the other side of the insulating base for coupling a cathode wiring element.
