1. An LED based light for replacing an incandescent bulb, comprising: a base having a first end and a second end;a connector fixed to the first end of the base, the connector adapted to physically connect to an incandescent light fixture;a light pipe extending from the second end of the base, the light pipe including a light receiving portion for receiving light and having an inner surface defining a cavity and an opposing exterior outer surface, with the inner surface configured to cause internal reflection of the received light and the outer surface configured to emit the reflected light;at least one LED arranged outward from the inner surface to produce light for the light receiving portion; anda heat dissipating structure for the at least one LED extending into the cavity. 2. The LED based light of claim 1, wherein: the at least one LED is disposed adjacent to the second end of the base, andthe light receiving portion is located at a proximal end of the light structure for receiving light produced by the at least one LED. 3. The LED based light of claim 2, wherein: the second end defines an annular platform for the at least one LED, andthe light structure is at least partially annularly shaped, with the light receiving portion opposing the platform. 4. The LED based light of claim 2, wherein the light receiving portion defines a cutout for receiving the at least one LED. 5. The LED based light of claim 1, further comprising: at least one additional LED arranged to face the inner surface, wherein the inner surface includes an interior light receiving portion for receiving light produced by at least one additional LED. 6. The LED based light of claim 1, wherein the heat dissipating structure is at least one of a plurality of longitudinally extending pins or a plurality of longitudinally extending fins. 7. The LED based light of claim 1, further comprising: an active heat dissipating device disposed for drawing air across the heat dissipating structure. 8. The LED based light of claim l, further comprising at least one of a thermal insulating shroud disposed about the base, or a thermal insulating shroud extending over an open distal end of the light structure to enclose the heat dissipating structure. 9. The LED based light of claim l, further comprising: electronics housed in the base, the electronics configured to supply power to the at least one LED, wherein the base defines a plurality of apertures configured to allow airflow between the electronics and an ambient environment external to the base. 10. The LED based light of claim l, wherein the at least one LED is arranged to emit light in a predetermined distribution that at least partially replicates that of an incandescent bulb. 11. The LED base light of claim 1, wherein the outer surface is contoured to form a conical profile. 12. The LED base light of claim l, wherein the outer surface is contoured to form a bulbous profile. 13. An LED based light, comprising: a base;at least one LED;a light pipe extending from the base, the light pipe including a light receiving portion arranged for receiving light produced by the at least one LED and having an inner surface defining a cavity and an opposing exterior outer surface, with the inner surface configured to cause internal reflection of the received light and the outer surface configured to emit the reflected light; anda heat dissipating structure for the at least one LED extending into the cavity. 14. The LED based light of claim 13, further comprising: a connector fixed to the base, the connector adapted to physically connect to an incandescent light fixture. 15. The LED base light of claim 1, wherein the light pipe has an open-ended annular structure with a proximal end including the light receiving portion, the cavity in fluid communication with an ambient environment, the exterior outer surface extending radially outward of the base and a distal end configured to emit the reflected light. 16. The LED based light of claim 15, further comprising: at least one additional LED arranged within the cavity to emit light from the cavity in a direction of a longitudinal axis of the LED based light to supplement light emitted from the distal end of the light pipe. 17. The LED based light of claim 16, wherein the least one additional LED is mounted on a circuit board supported by the heat dissipating structure. 18. The LED base light of claim 13, wherein the light pipe has an open-ended annular structure with a proximal end including the light receiving portion, the cavity in fluid communication with an ambient environment, the exterior outer surface extending radially outward of the base and a distal end configured to emit the reflected light. 19. The LED based light of claim 18, further comprising: at least one additional LED arranged within the cavity to emit light from the cavity in a direction of a longitudinal axis of the LED based light to supplement light emitted from the distal end of the light pipe. 20. The LED based light of claim 19, wherein the least one additional LED is mounted on a circuit board supported by the heat dissipating structure.
