Abstract
Description
- This technology relates to the field of light fixtures, and specifically relates to a light fixture with wireless control.
- A light fixture may include a housing that is mounted on a wall or other structure beside an area to be lighted. The housing may contain a lighting element, and may also contain a printed circuit board (PCB) with power control architecture for controlling the lighting element. In a light fixture having wireless control, the PCB may further include an antenna and other components that receive radio frequency (RF) signals and convert them into control signals that are compatible with the control architecture. These two functional areas of the PCB can be mounted on a single PCB or on multiple PCBs. However, the housing and the internal structure that supports the PCB inside the housing may obstruct the access needed for RF signals to reach the antenna most effectively.
- An embodiment may include a housing containing a lighting element and a single PCB or multiple PCBs that contain all or part of the components and circuitry for the power section and the RF section that are required to power and control the light source. For example, a first PCB section may have circuitry that controls the lighting element. A second PCB section may have an antenna and circuitry that converts RF signals into control signal input to the first PCB section. The second PCB section may be operatively interconnected with the first PCB section, and may be contained in the housing in an orientation projecting from the first PCB section.
- An embodiment may also include a housing having a first portion and a second portion projecting outward from the first portion. A lighting element may be contained in the housing. A first PCB may be contained in the first portion of the housing, and may have circuitry that controls the lighting element. A second PCB may have an antenna and circuitry that converts RF signals into control signal input to the first PCB. The second PCB may be operatively interconnected with the first PCB, and may be contained in the housing in an orientation projecting from first portion of the housing into the second portion of the housing.
- Summarized differently, an embodiment may include a housing containing a lighting element. The housing may have an outer wall with an aperture, and may contain a driver box. The housing may also contain a driver box cover that closes the driver box. The driver box cover may have an aperture. A first PCB section may be contained in the driver box, and may have circuitry that controls the lighting element. A second PCB section may have an antenna and circuitry that converts RF signals into control signal input to the first PCB section, and may be operatively interconnected with the first PCB section inside the driver box. The second PCB section may project outward from the driver box at various orientations relative to the first PCB section in order to optimize the reception of the RF signal. The second PCB section may project outward through the aperture in the driver box cover, and may project further outward through the aperture in the outer wall of the housing, with the antenna located at least partially outside the outer wall of the housing.

FIG. 7 is as partial view of another embodiment of a light fixture. - The following detailed description illustrates the general principles of the invention, examples of which are illustrated in the accompanying drawings.
- As shown in
FIG. 1 , an embodiment of alight fixture 10 may include ahousing 12 and alens 14. Thehousing 12 may be mounted on awall 16 in a position from which thelens 14 can direct light outward from a lighting element contained within thehousing 12. Aportion 18 of thehousing 12 may cover an antenna for wireless operation of the lighting element. - The
housing 12 in the illustrated embodiment includes acover 30 and abase 32. Thebase 32 is preferably configured to contain a motion sensor and/or a light sensor for automatic operation of thefixture 10. As shown separately in the exploded view ofFIG. 2 , thebase 32 may be shaped as a generally rectangular box with an openupper end 34,side walls 36, and abottom wall 38. Theupper end 34 may have aperipheral groove 39 for receiving agasket 40.Knockouts 42 may be provided in theside walls 36, and a pair of mountingbosses 44 may project from one of theside walls 36. Thebottom wall 38 may have one or more apertures for fasteners to attach thebase 32 to thewall 16 or other structure upon which thehousing 12 can be mounted as shown for example inFIG. 1 . Thebottom wall 38 may also have one or more apertures for receiving power lines from an electrical box in thewall 16 or other mounting structure. - The
cover 30 may have anouter wall 50, and may have an openinner side 52 opposite theouter wall 50. The openinner side 52 may have a peripheral size and shape matching that of thebase 32 at the openupper end 34, withedges 54 corresponding to theside walls 36 of thebase 32. Thecover 30 may also have mountingbosses 56 corresponding to themounting bosses 44 on thebase 32. Themounting bosses hinge pins 58 to support thecover 30 on thebase 32 for pivotal movement between a closed position, as shown inFIG. 1 , and a fully open position, as shown inFIG. 3 . Areleasable fastener 60 may secure thecover 30 in the closed position. - The
cover 30 may also have a generally rectangularperipheral surface 66 surrounding apanel support surface 68 adjacent to themounting bosses 56. A lighting element, which in the given example is alighting panel 70 with an array ofLEDs 72, may be installed over thepanel support surface 68. Atrim ring 74 may be installed over theperipheral surface 66, and may reach slightly inward over thelighting panel 70 to retain it in place on thepanel support surface 68. Aflange portion 80 of thelens 14 may be captured between thetrim ring 74 and theperipheral surface 66 of thecover 30, with abody portion 82 of thelens 14 projecting outward through thetrim ring 74. In the illustrated embodiment, this particular example of alens 14 is configured to disperse light from theLEDs 72 over a wide area. Further regarding the illustrated embodiment, the given example of a lighting element is alighting panel 70 with an array ofLEDs 72, but other suitable lighting elements include any devices that generate visible light such as, for example, incandescent, halogen, and CFL lamps. - Other parts of the
fixture 10 that are shown inFIG. 2 include aPCB assembly 88 with multiple PCB sections that are located on one PCB or multiple PCBs. In the illustrated example, thePCB assembly 88 includes first andsecond PCBs driver power board 90, has power control circuitry configured to control the lighting functions of theLEDs 72. Such functions include ON/OFF, color, lumen intensity, etc., and thedriver power board 90 may be configured accordingly in any suitable manner known in the art. The second PCB 92 also may be configured in any suitable manner known in the art, but unlike thedriver power board 90, the second PCB 92 includes anantenna 96 and circuitry configured to convert radio frequency signals into power signal input to thedriver power board 90. The second PCB 92 may thus be referred to as anRF control board 92. - In the assembled
fixture 10, theRF control board 92 is electrically coupled with thedriver power board 90 for theantenna 96 and signal converting circuitry to be operatively interconnected with the power control circuitry. With theantenna 96 and associated circuitry located on a separateRF control board 92 instead of on thedriver power board 90, theantenna 96 can be located and oriented differently from the location and orientation of the driver power board 94. This enables theantenna 96 be installed in thefixture 10 in a position and orientation best suited to receive RF signals from outside thehousing 12 without constraints that might otherwise be imposed by the position or orientation of thedriver power board 90. - The various sections of the
PCB assembly 88 may be operatively interconnected using connectors, fasteners, cables, or other known methods. In the illustrated embodiment, this particular example of anRF control board 92 is arranged relative to the associateddriver power board 90 as shown in greater detail inFIG. 4 . Specifically, a rightangle header block 100 reaches partially across thedriver power board 90. Connector pins 102 reaching through theheader block 100 are soldered to the twoboards boards RF control board 92 in the given example projects orthogonally from one side of thedriver power board 90. Other orientations may be employed as needed for particular implementations of a PCB assembly. - With further reference to
FIG. 2 , additional parts may include adriver box 110 and adriver cover 112. Thedriver cover 112 may be received over thedriver box 110 as shown inFIG. 5 . Thoseparts tabs 114 for fastening to thecover 30 at the inside of theouter wall 50. - The
driver power board 90 may be installed within thedriver box 110, and may be supported in thedriver box 110 by potting compound, mounting tabs, or the like (not shown). In this arrangement theRF control board 92 projects from thedriver power board 90 toward thedriver cover 112 at theouter wall 50. A slot 115 (FIG. 2 ) in thedriver cover 112 may be aligned with a slot 117 in theouter wall 50 to provide clearance for theRF control board 92 to project outward through theslots 115 and 117 and emerge from thecover 30 at that location. TheRF control board 92 preferably projects outward sufficiently for at least part of theantenna 96, and most preferably theentire antenna 96, to be located outward of thecover 30. This helps to ensure that theantenna 96 will receive RF signals with little or no interference from the other parts of thefixture 10. - The
portion 18 of thehousing 12 that serves as an antenna cover, as noted above with reference toFIG. 1 , is installed over the outwardly projecting portion of theRF control board 90. As shown inFIGS. 5 and 6 , theantenna cover 18 in the given example may include twocover parts first cover part 120 may be received upwardly through theslots 115 and 117, and may have lockingtabs 124 that snap into interlocked engagement with thedriver cover 112. Thesecond cover part 122 may fit over thefirst cover part 120 at theouter wall 50, and may be secured to theouter wall 50 byfasteners 128. Agroove 129 at the bottom of thesecond cover part 122 may receive an O-ring to provide a seal. - Further regarding the
cover 30 and thebase 32 of thehousing 12, those parts may be formed of any suitable material known in the art, such as aluminum, without the need for transmittance of RF signals. Theantenna cover 18, in which theRF control board 92 projects outward from the other parts of thehousing 12, is preferably formed of a nonmetallic material that allows RF signals to pass through such as, but not limited to, plastic. - As noted above, other orientations of the antenna may be employed for optimal RF reception. For example, in the embodiment shown partially in
FIG. 7 , the section of thePCB assembly 88 that includes theantenna 96 lays flat against theouter wall 50 of thecover 30. - While the forms of apparatus herein described constitute preferred embodiments of the invention, the invention is not limited to these precise forms, and changes may be made without departing form the scope of the invention.
