Claim 5:
6. An LED lamp heat dissipation structure with outward corrugations and reflector function, comprising:
a metal plate having a first predetermined shape portion, wherein a center of the metal plate is defined to have a second predetermined shape portion, an outer edge of the metal plate is formed to be a tapered portion with a plurality of outward corrugations and with a center at the second predetermined shape portion, the tapered portion has a predetermined inclination angle with respect to the second predetermined shape portion, two surfaces of the second predetermined shape portion are defined as an inner surface and an outer surface, respectively, and the tapered portion surrounds the inner surface to define an inner space; and
an LED lamp substrate, closely attached to the inner surface, wherein when the LED lamp substrate is empowered with electricity, a heat and a light are generated,
wherein most of the heat is conducted to the second predetermined shape portion through the inner surface, and then conducted to an ambient air through the outer surface, the tapered portion, and the outward corrugations, a part of the light directly irradiates outward, and another part of the light is reflected outward through the tapered portion, and
wherein the second predetermined shape portion is formed to have a convex platform protruded toward the inner space, the outer surface is formed to have a corresponding recess with a flat bottom, the tapered portion are uniformly cut at predetermined places to form a plurality of U-shaped pieces, each of the plurality of U-shaped pieces is located between two adjacent outward corrugations, a bottom of each of the plurality of U-shaped pieces faces toward the second predetermined shape portion, each of the plurality of U-shaped pieces is respectively bent toward the inner space to be connected with the convex platform, and a plurality of heat dissipation holes are respectively formed in original positions of the plurality of U-shaped pieces before being bent.
