## Abstract

A lighting system may include a plurality of suspenders and a beam configured to provide light in at least one direction. The suspenders may structurally support the beam from a ceiling and may provide electrical power and dimming control signals to the beam. The beam may include a plurality of light engines for emitting light. The light engines may be single sided or dual sided, and may transmit electrical power among each other. The dual sided light engines may emit light upwardly and downwardly from the beam, and the single sided light engines may emit light downwardly.

## Claims

### Claim 1

A light engine configured to emit light, comprising:
a body comprising a plurality of sides including a first side having a first surface and a second side having a second surface, the second side being mirror opposite to the first side with the first side extending along a first plane and the second side extending along a second plane that is spaced from the first plane;
a first light source disposed on the first surface of the first side of the body and extending away from the first surface of the first side in a first direction;
a first pair of wires having a first end and a second end, the first light source being connected to the first pair of wires between the first end and the second end and configured to receive electrical power through the first pair of wires;
a second light source disposed on the second surface of the second side of the body and extending away from the second surface in a second direction that is mirror opposite the first direction; and
a second pair of wires having a first end and a second end, the second light source being connected to the second pair of wires between the first end and the second end of the second pair of wires and configured to receive electrical power through the second pair of wires.

### Claim 2 (depends on 1)

The light engine of claim 1, further comprising a first plug and a second plug, wherein the first plug is connected to the first end of the first pair of wires and to the first end of the second pair of wires and the second plug is connected to the second end of the first pair of wires and to the second end of the second pair of wires.

### Claim 3 (depends on 2)

The light engine of claim 2, wherein the first plug and the second plug are selectively coupleable with one another.

### Claim 4 (depends on 3)

The light engine of claim 3, wherein the first plug includes a first pair of prongs connected to the first end of the first pair of wires and a second pair of prongs connected to the first end of the second pair of wires, the second plug includes a first pair of prongs connected to the second end of the first pair of wires and a second pair of prongs connected to the second end of the second pair of wires, wherein, when the first plug and the second plug are coupled to one another, the first pair of prongs of the first plug is electrically connected to the first pair of prongs of the second plug and the second pair of prongs of the first plug is electrically connected to the second pair of prongs of the second plug such that the first pair of wires is not electrically connected to the second set of wires.

### Claim 5 (depends on 1)

The light engine of claim 1, further comprising a connection ring disposed on the first surface of the body, wherein the connection ring is configured to be selectively coupled to a casing, the casing being configured to diffuse or reflect light emitted from the first light source.

### Claim 6 (depends on 5)

The light engine of claim 5, wherein the connection ring is threaded.

### Claim 7 (depends on 1)

The light engine of claim 1, wherein the body is made at least partially of a metal.

### Claim 8 (depends on 1)

The light engine of claim 1, wherein the body includes a plurality of fins configured to dissipate heat.

### Claim 9 (depends on 1)

The light engine of claim 1, wherein the body further comprises an opening extending along a length of the body between the first surface and the second surface and the first pair of wires and the second pair of wires extend through the opening.

### Claim 10 (depends on 1)

The light engine of claim 1, wherein the plurality of sides include a third side located between the first side and the second side that has an internal surface and an external surface and a fourth side that is located between the first side and the second and spaced from the third side that has an internal surface and an external surface, and wherein a first flange extends from the internal surface of the third side and a second flange extends from the internal surface of the fourth side.
