Abstract

A new method, system and apparatus for mounting mechanically, thermally and electrically light emitting diode (LED), crystals, arrays or packages. The above provides an LED assembly having reduced number of components and costs, superior heat dissipation, mechanical properties and a compact structure. The use of a grid or mesh allows for more efficient and inexpensive removal of heat from one or more LEDs within an LED fixture.

Claims

1. An LED light source comprising;

an LED chain formed from one or more LED packages, each said LED package having at least one anode lead and at least one or more cathode leads, so that at least one said anode lead of each said LED package is mechanically and electrically attached to one or more anode wires, said wires interconnecting so as to form a first wire mesh, and at least one said cathode lead is mechanically and electrically attached to one or more cathode wires, said wires interconnecting so as to form a second wire mesh, so that two or more said LED packages have anodes connected to said first wire mesh and cathodes connected to said second wire mesh;

wherein one or more of said anode wire mesh(es) and one or more of said cathode wire mesh(es) are electrically connectable to the appropriate polarity of a power source.

2. The LED light source of claim 1, wherein;

said anode and cathode wire mesh(es) are comprised of one or more of the following mesh types;

wire strand, welded wire mesh, woven wire mesh and/or expanded wire mesh.

3. The LED light source of claim 2 wherein;

each said anode and each said cathode wire meshes are inserted into a container shaped as a tube.

4. The LED light source of claim 3 wherein;

each said anode and cathode wire meshes are bent in 3-D space.

5. The LED light source of claim 4 wherein;

each said anode and cathode wire mesh(es) are secured within said tube to a slot.

6. The LED light source of claim 5 wherein;

said ends of said tube are capped by one or more caps, with at least one said cap having a lead to make electrical connection with one or more said anode wire mesh, and a lead to make electrical connection with one or more said cathode wire mesh.

7. The LED light source of claim 4 wherein;

said ends of said tube are capped by one or more caps, with at least one said cap having a lead to make electrical connection with one or more said anode wire mesh, and a lead to make electrical connection with one or more said cathode wire mesh.

8. The LED light source of claim 1, wherein;

said anode and cathode wire mesh(es) are comprised of one or more of the following mesh types;

expanded metal sheets and/or perforated metal sheets.
