## 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 casing configured to be selectively coupled to a light engine in a beam for generating light, the casing comprising:
a first portion configured to be selectively electrically and structurally coupled to the light engine;
a second portion including a light source configured to generate light; and
an intermediate member connecting the first and second portions to each other,
wherein the second portion is pivotally coupled to the intermediate member such that the second portion is rotatable with respect to the first portion about a first axis, and
wherein the second portion is rotatably coupled to the first portion such that the second portion is rotatable with respect to the first portion about a second axis different from the first axis,
wherein the first portion of the casing includes a first part configured to be selectively coupled to the light engine, and a second part connected to the intermediate member,
wherein the first and second parts of the first portion of the casing are rotatably coupled to each other such that the second part of the first portion of the casing is rotatable about the second axis with respect to the first part of the first portion of the casing, therefore enabling the intermediate member, together with the second portion of the casing, to be rotatable about the second axis.

### Claim 2 (depends on 1)

The casing of claim 1, wherein the first axis and the second axis are perpendicular to each other.

### Claim 3 (depends on 1)

The casing of claim 1, wherein the first portion of the casing includes a power jack that is configured to be selectively coupled to the light engine for transmitting electric power to the light source.

### Claim 4 (depends on 1)

The casing of claim 1, wherein the first portion of the casing includes a round threaded part that is configured to be selectively coupled to the light engine.

### Claim 5 (depends on 1)

The casing of claim 1, wherein the first portion of the casing includes a power jack that is configured to be selectively coupled to the light engine for transmitting electric power to the light source and a round threaded part that is configured to be selectively coupled to the light engine with the power jack disposed in a center of the round threaded part.

### Claim 6 (depends on 1)

The casing of claim 1, wherein the intermediate member further includes a pair of wires disposed inside of the intermediate member and configured to transmit electricity to the light source of the second portion of the casing.

### Claim 7 (depends on 1)

The casing of claim 1, wherein the light source is a light emitting diode (LED).

### Claim 8 (depends on 1)

The casing of claim 1, wherein the second portion of the casing is configured to rotate about the second axis together with the intermediate member.

### Claim 9 (depends on 1)

The casing of claim 1, wherein the first part and the second part of the first portion of the casing are both round and the second part is inserted within the first part.

### Claim 10 (depends on 9)

The casing of claim 9, wherein the first part of the first portion includes a groove extending all around the second part of the first portion, the second part of the first portion includes a protrusion inserted in the groove and the protrusion structurally couple the first and the second part of the first portion to each other and permit the first and the second part of the first portion to be rotatable about the second axis.
