Abstract: An LED lamp having a metal PCB bent polyhedrally and a method for manufacturing the LED lamp is provided, where a base constituting the metal PCB has a rectangular or geometric shape and is configured to have a plurality of base stepped grooves formed spaced apart from each other on the underside thereof in such a manner as to be bent upward or downward from the base to form reflection surfaces continuously, so that at the time when both ends of the base come into contact with the plane, the base has a geometric shape in which the base is located in space through the reflection surfaces continuously arranged.

Abstract: Provided is a headlight module having a thin plate type metal PCB, wherein the headlight module has the assembly structure of a metal PCB formed of a thin plate which is a thermal conductor and capable of being bent in various directions and including at least one protruded portion increasing a surface area on both sides, and a back plate coupled to the metal PCB through the protruded portion.
