Patent ID: 8430524

Claim:
An LED (light emitting diode) lamp, comprising: a base having a top surface and a bottom surface opposite to the top surface; a first LED module attached to the bottom surface of the base; a second LED module attached to the top surface of the base; a reflector engaged on the top surface of the base, having an outer surface facing and angled with the second LED module; a first envelope engaging on the bottom surface of the heat sink and receiving the first LED module; and a second envelope mounted on the top surface of the base and receiving the second LED module and the reflector, the second envelope having an annular sidewall to transmit the light generated by the second LED module, and a flange perpendicularly extending from a bottom edge of the sidewall; wherein light generated by the first LED module radiates to a bottom side of the LED lamp, and light generated by the second LED module is reflected by the outer surface of the reflector to radiate out and toward a lateral side of the LED lamp; and wherein the base has a disk-shaped projection extending from a center and an annular flange extending from an edge of the top surface, the projection and the flange cooperatively define an annular groove to receive the flange of the second envelope.
