Abstract

A conductive structure comprising: a plurality of conductive devices; a first conductive spring sheet, comprising a first connecting point; and a second conductive spring sheet, comprising a second connecting point. Each of the conductive devices comprises a first conductive end and a second conductive end. The second conductive end is connected to the second connecting point, and the first conductive end is connected to the first connecting point corresponding to the second connecting point to which the second conductive end is connected.

First claim

The invention claimed is:

1. A LED light bulb apparatus, comprising:
a first conductive base, comprising a first connecting point;
a second conductive base, comprising multiple second connecting points; and
multiple filaments, each filament having a first filament end to be fixed to the first connecting point and having a second filament end to be fixed to the second connecting point so as to keep the multiple filaments spreading as a three-dimensional light source, wherein the first connecting point and the second connecting point are made of metal material and the multiple filaments receive electrical power via at least one of the first connecting point and the second connecting point.

2. The LED light bulb apparatus of claim 1 , wherein the first conductive base and the second conductive have conductive paths for electrically connecting the filaments.

3. The LED light bulb apparatus of claim 1 , wherein the filaments are evenly distributed with respect to the first connecting base and the second connecting base.

4. The LED light bulb apparatus of claim 1 , further comprising a heat dissipation device comprising a first heat dissipation end and a second heat dissipation end, wherein a first conductive spring sheet is provided at the first heat dissipation end and the second conductive spring sheet is provided at the second heat dissipation end.

5. The LED light bulb apparatus of claim 4 , wherein the heat dissipation device is column-shaped.

6. The LED light bulb apparatus of claim 4 ,
wherein the first conductive spring sheet comprises a bending part and the heat dissipation device comprises an opening;
wherein a shape of the bending part corresponds to the opening;
wherein the bending part is through the opening and contacts the conductive device.
