The directional lighting fixture includes a first housing, a lighting element, an optical element, and a driver board. The lighting element is located within the first housing and substantially aligned with a central axis of the directional lighting fixture. The lighting element is configured to generate visible light. The optical element is positioned directly in front of the lighting element. The optical element is configured to direct the visible light generated by the lighting element in a specific direction. The driver board is electrically coupled to the lighting element and includes an antenna element. The driver board is offset from the central axis of the directional lighting fixture. The antenna element is positioned to be at least flush with the lighting element. ## Claims ### Claim 1 A directional lighting fixture, comprising: a first housing; a lighting element located within the first housing and substantially aligned with a central axis of the directional lighting fixture, the lighting element configured to generate visible light; an optical element positioned directly in front of the lighting element, the optical element configured to direct the visible light generated by the lighting element in a specific direction; and a driver board electrically coupled to the lighting element and including an antenna element, wherein the driver board is offset from the central axis of the directional lighting fixture, and wherein the antenna element is positioned to be at least flush with the lighting element. ### Claim 2 (depends on 1) The directional lighting fixture of claim 1, wherein the driver board is positioned at a vertical angle with respect to the central axis of the directional lighting fixture. ### Claim 3 (depends on 1) The directional lighting fixture of claim 1, wherein the driver board is substantially parallel with the central axis of the directional lighting fixture. ### Claim 4 (depends on 1) The directional lighting fixture of claim 1, wherein the first housing is constructed of a heat-conducting metal. ### Claim 5 (depends on 1) The directional lighting fixture of claim 1, wherein the lighting element is at least one LED. ### Claim 6 (depends on 1) The directional lighting fixture of claim 1, further comprising a second housing that is constructed of material that allows for radio frequency (RF) signals to pass through, wherein the first housing and the second housing are connected to one another by a keyed connection. ### Claim 7 (depends on 1) The directional lighting fixture of claim 1, further comprising a support constructed of a material that allows for RF signals to pass through, wherein the driver board is mounted to the support. ### Claim 8 (depends on 1) The directional lighting fixture of claim 1, wherein the directional lighting fixture is one of an LED lamp, an incandescent lamp, a compact fluorescent lamp (CFL), and a gas-discharge lamp. ### Claim 9 (depends on 6) The directional lighting fixture of claim 6, wherein the second housing includes a projection and the first housing defines a cutout that is shaped to generally correspond with the projection of the second housing to create the keyed connection. ### Claim 10 (depends on 6) The directional lighting fixture of claim 6, wherein the second housing includes an opening and two angled slots located along opposing sides of the opening of the second housing. ### Claim 11 (depends on 7) The directional lighting fixture of claim 7, wherein the support includes two shoulders that are located on opposing sides of the support. ### Claim 12 (depends on 7) The directional lighting fixture of claim 7, further comprising a fastening device that securely attaches the support to the first housing. ### Claim 13 (depends on 10) The directional lighting fixture of claim 10, wherein the driver board is configured to be installed to the second housing by sliding the driver board into the opening of the second housing along the two angled slots. ### Claim 14 (depends on 11) The directional lighting fixture of claim 11, wherein the first housing includes two mounting ribs, and wherein each shoulder of the support receives and rests against one of the two mounting ribs. ### Claim 15 A directional lighting fixture, comprising: a first housing constructed of a heat-conducting metal; a lighting element located within the first housing and substantially aligned with a central axis of the directional lighting fixture, the lighting element configured to generate visible light; an optical element positioned directly in front of the lighting element, the optical element configured to direct the visible light generated by the lighting element in a specific direction; and a driver board positioned at a vertical angle with respect to the central axis of the directional lighting fixture, wherein the driver board is electrically coupled to the lighting element and includes an antenna element, and wherein the driver board is offset from the central axis of the directional lighting fixture, and wherein the antenna element is positioned to be at least flush with the lighting element. ### Claim 16 (depends on 15) The directional lighting fixture of claim 15, further comprising a second housing that is constructed of material that allows for radio frequency (RF) signals to pass through, wherein the first housing and the second housing are connected to one another by a keyed connection. ### Claim 17 (depends on 15) The directional lighting fixture of claim 15, further comprising a support constructed of a material that allows for RF signals to pass through, wherein the driver board is mounted to the support.
