LED bulb with heat sink

1. A LED bulb comprising

a LED driver;

a LED module electrically connected to said LED driver;

a plurality of light emitting diodes electrically connected to said LED module for illumination thereof;

a heat sink surrounding said LED driver and said LED module; and

a body of silicone between and in contact with said LED driver and said heat sink for transferring heat generated in said LED driver from said LED driver to said heat sink, said body of silicone being between and in contact with said LED module and said heat sink for transferring heat generated in said LED module from said LED module to said heat sink.

2. A LED bulb as set forth in claim 1 wherein said heat sink is made of aluminum.

3. A LED bulb as set forth in claim 2 wherein said heat sink 12 is of hollow tubular shape with a circumferential array of spaced apart ribs for channeling a flow of ambient air thereover.

4. A LED bulb comprising

a LED driver;

a LED module electrically connected to said LED driver;

a plurality of light emitting diodes electrically connected to said LED module for illumination thereof;

a heat sink of aluminum surrounding said LED driver and having a circumferential array of spaced apart ribs for channeling a flow of ambient air thereover;

a body of silicone circumferentially surrounding said LED driver and disposed between said LED driver and said heat sink for transferring heat generated in said LED driver from said LED driver to said heat sink, said body of silicone being between and in contact with said LED module and said heat sink for transferring heat generated in said LED module from said LED module to said heat sink.

5. A LED bulb comprising

a LED driver;

a LED module;

a plurality of wires electrically connecting said LED driver to said LED module;

a plurality of light emitting diodes electrically connected to said LED module for illumination thereof;

a heat sink of aluminum for dissipating heat generated by said LED driver and said LED module during operation thereof; and

a body of silicone circumferentially surrounding said LED driver and said wires and being disposed between and in contact with said LED driver and said heat sink for transferring heat generated in said LED driver from said LED driver to said heat sink.

6. A LED bulb as set forth in claim 5 wherein said body of silicone is disposed between said LED module and said heat sink for transferring heat generated in said LED module from said LED module to said heat sink.

7. A LED bulb as set forth in claim 5 wherein said heat sink is of hollow tubular shape and houses said LED driver therein.

8. A LED bulb comprising

a plug at one end for connection to a source of electricity;

a lens at an opposite end from said plug;

a heat sink of aluminum extending between said plug and said lens and including a circumferential array of spaced apart ribs;

a LED driver within said heat sink;

a LED module within said lens;

a plurality of wires electrically connecting said LED driver to said LED module;

a plurality of light emitting diodes electrically connected to said LED module for illumination thereof; and

a body of silicone circumferentially surrounding said LED driver and said wires and being disposed between and in contact with said LED driver and said heat sink for transferring heat generated in said LED driver from said LED driver to said heat sink.

9. A LED bulb as set forth in claim 8 wherein said body of silicone is disposed for transferring heat generated in said LED module from said LED module to said heat sink.

10. A LED bulb as set forth in claim 8 wherein said plug is threaded.
