Claim 0:
1. 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 has an interior surface and 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 each outward protrusion of the outward corrugations consists of two sections of the metal plate and the two sections in each outward protrusion form two inner walls, each of the two inner walls has an inner wall surface recessed from the inner space above the inner surface and connected with the interior surface of the tapered portion, the two inner wall surfaces face each other in a longitudinal direction of the tapered portion, 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.
