## Abstract

A family of lighting systems uses a small number of standard parts or extrusions. The extrusions include end elements, spars, and heat sinks. Lightbars and uplights, having heat sinks, LED arrays, and lenses, use heat sinks with the same extrusion profile. The extruded parts can be slid together and then held in place by screws holding side panels to form a housing. Conditioned electrical power can drive the LED arrays. The conditioned power can be produced by power conditioners mounting on the housing. IP65, or better, components can be used to produce a rugged outdoor system.

## Claims

### Claim 1

A lighting system comprising:
at least one spar;
at least one heat sink element;
at least one LED assembly comprising at least one LED array and at least one lens;
at least one light bar;
two uplight panels, wherein each one of the uplight panels comprises an uplight heat sink and an uplight LED assembly wherein the uplight LED assembly is attached to the uplight heat sink, wherein the uplight heat sink is one of the at least one heat sink elements, and wherein the uplight LED assembly is one the at least one LED assemblies;
a housing comprising a first end, a second end, and two side panels;
a cover covering the top of the housing while leaving clear a lens of the uplight panels; and
a lens frame and a bottom lens, wherein the lens frame holds the bottom lens such that light from the at least one light bar passes through the bottom lens before exiting the lighting system.

### Claim 2 (depends on 1)

The lighting system of claim 1 wherein the lens frame is attached to the first end and the second end, and wherein light exiting the at least one LED array passes through the bottom lens before exiting the lighting system.

### Claim 3 (depends on 2)

The lighting system of claim 2 further comprising:
two end elements, each comprising an end extrusion profile the end extrusion profile configured such that each end element further comprises a floor T-channel and wherein the lens frame is attached by fasteners in bottom T-channels of the first end and of the second end.

### Claim 4 (depends on 3)

The lighting system of claim 3 wherein the side panels are attached by screws threaded into screw grooves of the end elements and into screw engagers of the at least one spar.

### Claim 5 (depends on 3)

The lighting system of claim 3 wherein a spar extrusion profile is configured such that each of the at least one spars further comprises a cross comprising an upright and a crossbeam.

### Claim 6 (depends on 3)

The lighting system of claim 3 wherein a spar extrusion profile is configured such that each of the at least one spar further comprises a top channel, and a bottom channel.

### Claim 7 (depends on 6)

The lighting system of claim 6 wherein a fastener attaches the cover to the top channel of the at least one spar.

### Claim 8 (depends on 6)

The lighting system of claim 6 wherein the spar extrusion profile is configured such that each of the at least one spar further comprises a cross comprising an upright and a crossbeam, and wherein screw engagers are positioned on the ends of the cross beams.

### Claim 9 (depends on 1)

The lighting system of claim 1 further comprising a second spar that is one of the at least one spars.

### Claim 10

A lighting system comprising:
at least one spar, each comprising a spar extrusion profile that is the same for all the at least one spar;
two end elements, each comprising an end extrusion profile that is the same for all the end elements;
