LED lamp having metal PCB which banding type polyhedric body and Manufacturing Method Thereof

摘要

In the present invention, the base forming the metal PCB is of a rectangular or geometric shape, and a plurality of base step grooves are formed in the lower part of the base to be parallel to each other or spaced apart to have an inclination, and are continuously bent in a desired direction among the upper or lower part of the base. A reflective surface is formed, and the base is installed to have a geometric shape positioned in a space through a continuous reflective surface when both ends of the base are in contact with a plane, and to an LED lamp having a multi-folded metal PCB ratio and a manufacturing method thereof.
