Decorative lamp strip

A decorative lamp strip, comprising:

• a. a flat electric wire, comprising:
• i. a middle strand conductor for series connection,
• ii. an upper strand conductor for parallel connection, and
• iii. a lower strand conductor, also for parallel connection;
• a plurality of square holes on an electric wire body for installing each main seat;
• b. each of the main seat having a L-shaped seat body thereof for installing a main seat in the position of each square hole on the flat electric wire, each main seat comprising:
• i. a cylindrical pit at the center on the upper side of main seat,
• ii. two lateral U-shaped concave edges on the inner wall on the two sides of the cylindrical pit and along the length of said inner walls,
• iii. a dovetail slot on the front bottom side of the main seat, and
• iv. a set of "arrowhead" shaped snap pillar at the center of vertical plate on the lower side of the main seat body;
• c. each fixing plate for installing the main seat on the flat electric wire, each fixing plate comprising:
• i. a plate body with an upward dovetail tenon, and
• ii. a square hole at the center of the plate body;
• to insert the dovetail tenon into the dovetail slot and to insert a set of "arrowhead" shaped snap pillar into the square holes so as to fix the main seat in the position of square holes on the flat electric wire;
• d. a set of series connected conductive piece or a set of a first and a second parallel connected conductive pieces, each set thereof comprising:
• i. a left conductive piece as a lateral Z-shaped plate body of which the lower end is folded into a vertical positioning piece toward left side and then folded into two horizontal sharp teeth toward front side, and the upper end is inserted into a lateral U-shaped concave edge on the left side of cylindrical pit on the main seat, and
• ii. a right conductive piece as a lateral Z-shaped plate body of which the lower end is folded into a vertical positioning piece toward right side and then folded into two horizontal sharp teeth toward front side, and the upper end is inserted into a lateral U-shaped concave edge on the right side of cylindrical pit on the main seat;
• e. each lamp seat as a seat body in the shape of a reverse top hat, comprising:
• i. a central cylindrical pit for installing a bulb, and
• ii. two openings on the two sides at the bottom of seat body and leading to the cylindrical pit;
• to insert a bulb into the cylindrical pit on the lamp seat which is then inserted into the cylindrical pit on the main seat;
• and
• f. each bulb with two conductive legs at lower end to be inserted into the cylindrical pit on the lamp seat, wherein these two conductive legs respectively pass through the two openings at the bottom of lamp seat body and then to be folded upward to contact the two outer side walls of the lamp seat body;
• therefore, to install each main seat in the position of each square hole on the flat electric wire, to insert a set of "arrowhead" shaped snap pillar on the main seat into the square hole, to install a fixing plate on the said set of "arrowhead" shaped snap pillar, to thrust the two horizontal sharp teeth of each set of series connected or parallel connected conductive piece into the middle or upper and lower strand conductors of the flat electric wire, and to insert the lamp seat with a bulb into the cylindrical pit on each main seat, then the said decorative lamp strip is well combined.
