## Abstract

A laser light display system that includes a plurality of laser heads, a router controller and a plurality of transmission cables is disclosed. The system includes control signal receivers associated with the laser heads and a laser controller that includes a relay, signal output ports, and a programmable logic controller for providing output signals for the control of the laser heads each which emit a single static and motionless beam of radiation of visible light.

## Claims

### Claim 1

A laser light display system comprising a plurality of laser heads and a router controller and a plurality of transmission cables,
each said laser head devices further comprising a single laser diode, a control signal receiving means, a laser controller and power source, wherein said laser controller comprises a relay, and
said a router controller further comprising a plurality of output ports, a programmable logic controller to provide output signals to control the activation of said laser head devices, and
wherein said transmission cables are in communication with said router controller and transmit control signals from said router controller to said laser head devices, and
wherein said laser heads are enclosed by a casing through which a single window defining an exterior optic surface and said laser emits a single static and motionless beam of radiation of visible light through said window.

### Claim 2 (depends on 1)

The system recited in claim 1 wherein the router controller further comprises a DMX input port and said programmable logic controller can be activated by a signal received from said DMX input port.

### Claim 3 (depends on 1)

The system recited in claim 1 wherein said laser is classified as a FDA/IEC Class IIIB.

### Claim 4 (depends on 1)

The system recited in claim 1 further comprising a second controller router in communication with said first controller router and configured in a slave operating mode and wherein said second controller controls a plurality of laser heads.

### Claim 5 (depends on 1)

The system recited in claim 1 wherein said plurality of laser heads emit the substantially the same wavelength of radiation.

### Claim 6 (depends on 1)

The system of claim 1 wherein at least three laser heads are positioned at locations more than 3 feet from one another.

### Claim 7 (depends on 6)

The system of claim 6 wherein each beam is projected in a vector having a different direction from the other beams.

### Claim 8 (depends on 6)

The system of claim 6 wherein each beam is projected in a different plane.

### Claim 9 (depends on 6)

The system of claim 6 wherein each laser is sequentially activated and then deactivated at unique time periods.

### Claim 10

A method of creating a laser light show comprising positioning at least three laser heads at discrete locations on a support structure, wherein said laser heads comprise FDA/IEC Class IIIB devices, and each said laser head further comprises a diode and driver that creates a single static and stationary beam and a controller, said method further comprising orienting said laser heads in three different directions, and then activating a first laser head to project a visible light beam to define a first vector for a first predetermined time, activating a second head to project a visible light beam to define a second vector after said first predetermined time has elapsed for a second predetermined period of time, and after said second predetermined time has lapsed, activating a third laser head to project a visible light beam to define a third vector.

### Claim 11 (depends on 10)

The method recited in claim 10 wherein each said vector is oriented in a different direction.

### Claim 12 (depends on 10)

The method recited in claim 10 wherein said vectors are in at least two separate planes.

### Claim 13 (depends on 10)

The method recited in claim 10 wherein said laser heads are positioned around the periphery of a room and at least one beam is directed toward the center of said room.
