LED BULB WITH HEAT DISSIPATER
First Claim
1. A LED bulb having a heat dissipater, said LED bulb comprising:
- a base, comprising a conducting portion and an isolation tube positioned at a bottom side of said conducting portion;
a heat dissipater, joining on said isolation tube and having a hollow tunnel;
said hollow tunnel having a plurality of fins extending perpendicularly and positioned with an interval from one another in a radial fashion, wherein said fins comprises an outer flange connected to a heat dissipation ring, and said heat dissipation ring circularly connected to said fins;
a LED module, comprising a circuit board fixed to said heat dissipater and a plurality of LED scattered on said circuit board; and
a cap, assembled to said heat dissipater to house said LED module.

Abstract
A LED bulb has a heat dissipater. The LED bulb includes a base, a heat dissipater, a LED module and a cap. The base has a conducting portion and an isolation tube positioned at a bottom portion of the conducting portion. The heat dissipater is assembled to the isolation tube. The heat dissipater has a hollow tunnel and a plurality of fins extending perpendicularly and positioned with an interval from one another in a radial fashion. The fins have an outer flange connected to a heat dissipation ring, and the heat dispensing ring is circularly connected to the fins. The LED module has a circuit board fixed to the heat dissipater and a plurality of LED scattered on the circuit board. The cap is assembled to the heat dissipater to house the LED module. The LED bulb increases the air circulation and accordingly promotes the heat dissipation effect.
