LED bulb with internal heat dissipating structures

摘要

An LED based light for replacing an incandescent bulb comprises a base having a first end and a second end. A connector is fixed to the first end of the base and adapted to physically connect to an incandescent light fixture. A light structure extends from the second end of the base and has an inner surface defining a cavity and an opposing exterior outer surface, and at least one LED is arranged outward from the inner surface. A heat dissipating structure for the at least one LED extends into the cavity.

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; and a heat dissipating structure for the at least one LED extending into the cavity.
