1. An LED lamp comprising:
a heat dissipating base; an LED assembly, comprising a plurality of LEDs, in thermal communication with the heat dissipating base; a bulb disposed over the LED assembly and coupled to the heat dissipating base, the bulb defining an inner surface and an upper surface, wherein the upper surface is located along the inner surface of the bulb; and a reflective insert disposed inside the bulb and configured to reflect a portion of light generated by the LED assembly in a substantially downward direction, the reflective insert comprising:
an inner edge defining a circular opening including a circumference, wherein the circumference of the circular opening of the reflective insert allows a remaining portion of light generated by the LED assembly to pass through the reflective insert and radiate in a substantially upward direction towards the upper surface of the bulb; andan outermost edge that is flush against the inner surface of the bulb.
