Abstract

A method of manufacturing multiple light emitting diode lighting assemblies each having a different initial light output is provided. A first heat sink is manufactured and a first platform assembly with a plurality of light emitting diodes is formed with an automated device. The automated device selects a first predetermined lumen output. A second heat sink is then manufactured using the same manufacturing process, and a second platform assembly with a plurality of light emitting diodes is formed with the automated device. During this time, the automated device selects a second predetermined lumen output based on information inputted into the automated device.

Claims

1. A method of manufacturing light emitting diode lighting assemblies having different initial light outputs comprising:

manufacturing a first heat sink using a manufacturing process;

forming a first platform assembly having a plurality of light emitting diode lighting elements on a first substrate with an automated device;

during the step of forming the first platform assembly, selecting with the automated device a first predetermined lumen output;

manufacturing a second heat sink using the same manufacturing process as used to manufacture the first heat sink;

inputting information into the automated device;

forming a second platform assembly having a plurality of light emitting diode lighting elements on a second substrate with the automated device; and

during the step of forming the second platform assembly, selecting a resistor with the automated device and forming the resistor onto the second substrate to provide a second predetermined lumen output based on the information inputted into the automated device.

2. The method of claim 1 wherein the first predetermined lumen output is at least 450 lumens.

3. The method of claim 2 wherein the second predetermined lumen output is at least 800 lumens.

4. The method of claim 1 wherein the first predetermined lumen output is at least 800 lumens.

5. The method of claim 4 wherein the second predetermined lumen output is at least 1100 lumens.

6. The method claim 1 wherein the first predetermined lumen output is at least 1100 lumens.

7. The method of claim 6 wherein the second predetermined lumen output is at least 1600 lumens.
