Abstract

A light emitting diode lamp is disclosed to include a lamp base connectable to a lamp socket, a bulb fastened to the top side of the lamp base, and a light emitting diode lamp voltage-dropping circuit module fixedly mounted in the holding space inside the lamp base and holding light emitting diode close to the bottom end of the bulb for enabling the light emitted by the light emitting diode to pass to the outside through the whole area of the bulb.

Claims

1. A light emitting diode lamp comprising:

a lamp base, said lamp base having a bottom wall, a peripheral wall extending around the periphery of said bottom wall and defining with said bottom wall a holding space, an outer thread extending around said peripheral wall for fastening to a lamp socket, a negative electrode installed in said peripheral wall, and a positive electrode installed in the center of said bottom wall;

a bulb, said bulb having a bottom side fastened to the top side of said lamp base; and

at least one light emitting diode;

wherein said at least one light emitting diode is respectively installed in a light emitting diode lamp voltage-dropping circuit module, which is mounted in said holding space inside said lamp base to hold said at least one light emitting diode close to the bottom end of said bulb for enabling the light emitted by said at least one light emitting diode to pass through the whole area of said bulb to the outside of the light emitting diode lamp.

2. The light emitting diode lamp as claimed in claim 1, wherein said light emitting diode lamp voltage-dropping circuit module has a positive terminal and a negative terminal respectively electrically coupled to said positive electrode and said negative electrode.

3. The light emitting diode lamp as claimed in claim 1, wherein said at least one light emitting diode each is a chip light emitting diode.
