Abstract: The present invention discloses a method and structures of a miniaturized line lamp. Metal wires are crossed over at two sides of an LED and are in a state of clipping, allowing the LED to be located at a same plane of the metal wires of an electric wire. Electrode positions at shorter edges of two sides of the LED are perpendicular to the metal wires and each across corner is formed respectively with a notch area which is free of electrode. A no-notch position of electrode at the other end of each side provides exactly for contact of two metal wires to form a loop. Therefore, a size of the line lamp device can better comply with a requirement of miniaturization.
