## Abstract

Embodiments of the present invention provide a light emitting diode (LED) lighting fixture and methods of manufacturing the same. In various embodiments, the LED lighting fixture comprises a lighting fixture body and one or more luminaires. The one or more LED modules are operatively and securely fixed to the lighting fixture body. Each LED module comprises at least one LED, and a heat sink. The at least one LED is mounted within the LED module such that light emitted by the at least on LED is emitted in an upward direction. The heat sink is positioned such that at least a portion of the light emitted by the at least one LED is not incident upon the heat sink. Additionally, the heat sink is permanently fixed to the lighting fixture body.

## Claims

### Claim 1

A light emitting diode (LED) module comprising:
a raised base;
one or more LEDs;
an optical assembly consisting of:
a lens,
a light spreader disk, and
a bulb,
wherein:
the lens is securely fixed directly to the light spreader disk and positioned between the light spreader disk and the one or more LEDs, such that at least a portion of the light emitted by the one or more LEDs is incident upon the light spreader disk and the bulb is an envelope of the LED module, and
the optical assembly is removably mounted to the raised base, such that the optical assembly is independently replaceable with another optical assembly; and
a board, said one or more LEDs being fixedly mounted to said board and said board being mounted to a surface of said raised base,
wherein;
the mounting of the board on the surface of said raised base places said one or more LEDs in a raised position within the LED module, and
the optical assembly is separate from said one or more LEDs.

### Claim 2 (depends on 1)

The LED module of claim 1, wherein the LED module is configured to emulate the aesthetic appearance of one of a clear light bulb, a chandelier light bulb, a flame tip light bulb, a G lamp bulb, or an incandescent bulb having a filament.

### Claim 3 (depends on 1)

The LED module of claim 1, wherein said light spreader disk is positioned such that at least a portion of the light emitted by the one or more LEDs is emitted toward the light spreader disk.

### Claim 4 (depends on 3)

The LED module of claim 3, wherein the light spreader disk is etched.

### Claim 5 (depends on 1)

The LED module of claim 1, wherein said one or more LEDs are operatively and fixedly mounted into thermally conductive communication with at least one heat sink, said board providing at least a portion of a thermally conductive and electrically isolated path for said thermally conductive communication.

### Claim 6

A modular assembly comprising:
one or more LED modules each comprising at least one LED, a board, and a raised base, the at least one LED being operatively mounted to the board; and
an optical assembly corresponding to and separate from each of the one or more LED modules, each optical assembly consisting of:
a lens,
a light spreader disk, and
a bulb,
wherein the lens is securely fixed to the light spreader disk and positioned between the light spreader disk and the at least one LED such that at least a portion of the light emitted by the at least one LED is incident upon the light spreader disk and the bulb is an envelope of the LED module, and
wherein:
the board is mounted to said raised base, wherein the mounting of the board on said raised base places said at least one LED in a raised position within the one or more LED modules, and
the optical assembly is separate from said at least one LED.

### Claim 7 (depends on 6)

The modular assembly of claim 6, wherein at least a portion of said one or more LED modules is integrally formed with a lighting fixture body.

### Claim 8 (depends on 7)

The modular assembly of claim 7, wherein the lighting fixture body comprises a decorative housing such that said one or more LED modules are contained within said decorative housing.

### Claim 9 (depends on 7)

The modular assembly of claim 7, wherein said lighting fixture is a chandelier or lantern style lighting fixture.

### Claim 10 (depends on 7)

The modular assembly of claim 7, wherein said lighting fixture is configured for indoor or outdoor use.

### Claim 11 (depends on 6)

The modular assembly of claim 6 wherein said LED module is configured to emulate a decorative effect and light spread from a traditional or decorative incandescent or halogen bulb.

### Claim 12 (depends on 6)

The modular assembly of claim 6, further comprising a heat sink, wherein:
at least a portion of said one or more LED modules is integrally formed with a lighting fixture body;
said heat sink is permanently fixed to said lighting fixture body; and
said at least one LED is securely mounted into said lighting fixture such that the at least one LED is fixedly mounted into thermally conductive communication with the heat sink, said board providing at least a portion of a thermally conductive and electrically isolated path for said thermally conductive communication.

### Claim 13 (depends on 6)

The modular assembly of claim 6, wherein said light spreader disk is positioned such that at least a portion of light emitted by said at least one LED is emitted toward said light spreader disk.

### Claim 14 (depends on 13)

The modular assembly of claim 13, wherein said light spreader disk is etched.

### Claim 15 (depends on 6)

The modular assembly of claim 6, further comprising at least one driver circuit component, wherein said driver circuit component is configured to control a current flowing through said at least one LED.

### Claim 16 (depends on 15)

The modular assembly of claim 15, wherein said at least one driver circuit is hard-wired into a lighting fixture.

### Claim 17

At least one LED module, each LED module comprising:
a raised base;
one or more LEDs;
an optical assembly separate from said one or more LEDs and consisting of: a lens, a light spreader disk, and a bulb; and
a board, said one or more LEDs being mounted to said board and said board being mounted to a portion of said raised base,
wherein:
the mounting of the board on the portion of said raised base places said one or more LEDs in a raised position within the LED module; and
the optical assembly is removably mounted over and separate from said one or more LEDs.

### Claim 18 (depends on 17)
