Patent abstract
An LED lamp structure includes a reflection cup, a metal heat sink for receiving a plurality of LEDs, and a heat conducting base. The heat conducting base has a slot for receiving the metal heat sink. The metal heat sink includes guiding planes for redirecting the output of an LED so as to change the angle of projected light. The metal heat sink is made of a good heat conductor with high thermal capacity so that heat produced by the LED is absorbed quickly and conducted to the heat conducting base. The reflection cup is flexed to an outer edge of the metal heat sink to provide a flat lighting characteristic.
