## Abstract

A light assembly having a projector integrally connected to a light bar. The projector and the light bar share power and control wires from a wire harness. The projector includes a projector aperture whereby light (oftentimes in a pattern or logo formation) passes therethrough and directs onto a ground surface. The projector includes a light assembly configured to hold the components for projection.

## Claims

### Claim 1

A light projector assembly comprising:
a projector integrally connected to a light bar;
the projector and the light bar sharing power and control wires from a wire harness;
the projector having a projector aperture whereby light passes therethrough and directs onto a ground surface;
the projector includes a light assembly configured to hold the components for projection;
the light assembly being clear allowing light to pass therethrough;
the light assembly being sealed so as to protect the projector and lens components wherein the lens components are sealed within the light assembly; and
a first power source wire from the vehicle is soldered directly to a printed circuit board in a projector housing, a second power source wire soldered to the printed circuit board and extending to the light bar, wherein reducing wires and providing for a pass-through power configuration reduces parts and thus cost to the vehicle.

### Claim 2 (depends on 1)

The light projector assembly of claim 1 wherein the light components includes a lens stack.

### Claim 3 (depends on 2)

The light projector assembly of claim 2 wherein the lens stack has a minimized or reduced heights size and include a customizable image slide wherein the customizable image slide enables customization with preferred logos and/or patterns for projection onto a ground surface.

### Claim 4 (depends on 1)

The light projector assembly of claim 1 wherein a cover is configured to house and cover the light assembly.

### Claim 5 (depends on 2)

The light projector assembly of claim 2 wherein the lens stack comprises a collimation lens set, an image slide, and a zoom and aberration lens set.

### Claim 6 (depends on 5)

The light projector assembly of claim 5 wherein the cover includes an endcap and covers a front portion of the light assembly.

### Claim 7 (depends on 6)

The light projector assembly of claim 6 wherein the first cover connects to the second cover and covers a rear portion of the light assembly.

### Claim 8 (depends on 4)

The light projector assembly of claim 4 wherein the endcaps cover both the first section and the second section of the cover so as to retain the light assembly onto the end of the light bar.

### Claim 9 (depends on 4)

The light projector assembly of claim 4 wherein potting material is used inside of the cover to seal from external environmental conditions.

### Claim 10

A light projector assembly comprising:
a projector integrally connected to a light bar;
the projector and the light bar sharing power and control wires from a wire harness;
the projector having a projector aperture whereby light passes therethrough and directs onto a ground surface;
the projector includes a light assembly configured to hold the components for projection;
a lens stack, the lens stack including a collimation lens set, an image slide, and a zoom and aberration lens set; and
the light assembly being sealed so as to protect the projector and lens components wherein the lens components are sealed within the light assembly.
wherein reducing wires and providing for a pass-through power configuration reduces parts and thus cost to the vehicle.

### Claim 11 (depends on 10)

The light projector assembly of claim 10 wherein the cover includes an endcap and covers a front portion of the light assembly.

### Claim 12 (depends on 11)

The light projector assembly of claim 11 wherein the first cover connects to the second cover and covers a rear portion of the light assembly.

### Claim 13 (depends on 12)

The light projector assembly of claim 12 wherein the endcaps cover both the first section and the second section of the cover so as to retain the light assembly onto the end of the light bar.

### Claim 14 (depends on 13)

The light projector assembly of claim 13 wherein potting material is used inside of the cover to seal from external environmental conditions.

### Claim 15 (depends on 10)

The light projector assembly of claim 10 wherein a first power source wire is soldered directly to a printed circuit board in a projector housing, a second power source wire soldered to the printed circuit board and extending to the light bar.
