The disclosed embodiments relate to LED connectors that are adapted for receiving electrical energy from a power source, and mounting an LED light source to a lighting board via conductive fasteners, whereby the LED connector transmits power from the power source and direct to the conductive fasteners, thereby powering the LED light source.
LED boards have traditionally been mounted to a lighting frame by way of soldered connections. Applicant believes that the present application provides advances over the state of the art.
Advantages of the present disclosure will be set forth in and become apparent from the description that follows. Additional advantages of the disclosure will be realized and attained by the methods and systems particularly pointed out in the written description and claims hereof, as well as from the appended drawings.
Among other things, connectors for a lighting board are disclosed that are adapted for receiving electrical energy from a power source, and via one or more conductive fasteners. This can facilitate mechanically connecting a lighting board to a lighting frame and transmitting power from a power source into electrical contacts in a lighting board to power a lighting board.
Thus, in one embodiment, a connector for a lighting board is provided that is adapted for receiving electrical energy from a power source, and via one or more conductive fasteners. The connector can both mechanically connect a lighting board to a lighting frame and transmit power from a power source into electrical contacts in a lighting board to power a lighting board.
In accordance with some implementations, the connector can include a central body containing first and second electrical contacts with respective positive and negative leads running through and extending away therefrom and toward the power source and a connector base capable of being seated against a first side of the lighting frame when the connector is connected to the lighting frame. The connector base can have a terminal portion which is positioned against an opening in the lighting frame when the connector is connected to the lighting frame. The connector base can include one or more members for mounting the connector to the lighting frame. The mounting member can be, for example, a first mounting wing extending in a first direction away from the body of the connector. If desired, the connector base can include a second wing extending away from the connector in a second direction. In such an embodiment, a first bottom surface of the first wing and a second bottom surface of the second wing can be on a common plane and form a connector base seat. The connector base seat can be positionable against the first side of the lighting frame for mounting the connector to the lighting frame.
In accordance with further aspects, the first mounting wing can extend further away from the connector base than the second mounting wing, whereby the first and second mounting wings, in a plan view thereof, can be asymmetrically disposed on the connector. The first and second wings can fit into respective first and second asymmetrically disposed tabs on a lighting frame such that a predetermined electrical polarity configuration is obtained between the connector and a lighting frame when the connector is positioned on a lighting frame. A centerline through the first and second mounting wings that extends away from the body can form a straight line, if desired. The first and second conductive contacts can include respective first and second top portions, electrically connected to respective positive and negative leads. Respective first and second bottom portions of the connector can accordingly extend to the terminal portion of the connector base to define both respective first and second fittings which are said first and second electrical contacts. The terminal portion can both mechanically receive and electrically connect with respective first and second conductive fasteners. The connector can mechanically receive and electrically connect with respective first and second electrical contacts of a lighting board. The lighting board can be mechanically secured to a lighting frame.
In further accordance with the disclosure, the first and second fittings at the terminal portion can be female threaded for receiving male threaded first and second conductive fasteners. The top of the first contact can be fused to the positive lead, and the top of the second contact can be fused to the negative lead. The terminal portion of the connector base can extend below a surface plane defined by the first and second bottom surfaces of the respective first and second wings. The terminal portion of the connector base can extend into an opening of a lighting frame and can be flush with an interior surface of a lighting frame, against which a rear surface of a lighting board can be disposed when secured to the electrical connector. An outer end of the first wing can include a first wing eyelet, and/or an outer end of the second wing can include a second wing eyelet. The first and second wing eyelets can be adapted for aligning with eyelets in respective first and second mounting tabs on a lighting frame for releasable locking of the connector to a lighting frame. The connector body can be molded plastic or other suitable material.
In yet further accordance with the disclosure, a lighting system is provided including a connector as recited herein and a lighting frame. The lighting frame can include an opening through which the terminal portion of the connector base extends, and first and second tabs which can be asymmetrically disposed about the opening for engaging respective first and second wings and releasably locking the connector thereto. The first and second mounting tabs can open towards opposing directions about the frame opening. For example, the connector can be twisted in a first direction about its center axis for obtaining a locked configuration against the first and second mounting tabs. Moreover, the connector can be twisted in a second, opposing direction about its center axis for obtaining a released configuration against the first and second mounting tabs. The opening in the lighting frame can be circular or other suitable shape, wherein the terminal portion of the connector can be capable of unobstructed twisting therein.
In accordance with a further aspect, the lighting frame can be thermally conductive, so that mechanically connecting a lighting board with first and second conductive fasteners can electrically connect a lighting board to the connector, and/or bias a lighting board to the thermally conductive surface of the lighting frame to permit and facilitate dissipation of thermal energy resulting from electrically powering a lighting board through the connector. If desired, the raised height of the terminal portion of the base of the connector can be equivalent to the thickness of a base of the lighting frame, against which a lighting board is disposed when installed. The opening and tabs can be mutually width-wise aligned on the lighting frame, and offset from a width-wise centerline of the base of the lighting frame by a first offset distance, whereby, with first and second contacts of a lighting board offset from a width-wise lighting board centerline by the first offset distance, a predetermined electrical polarity configuration can be obtained between the connector and a lighting board when the connector connects a lighting board to the lighting frame. The system can further include a lighting board, such as a LED array or LED point source.
In accordance with further aspects, the lighting system can include a connector and one or more conductive fasteners (e.g., screws) for mechanically connecting a lighting board to a lighting frame and electrically connecting a lighting board to the first and second fittings. The system can include a plurality of spaced apart connectors chained to each other via common, continuous positive and negative leads.

In the disclosed embodiments, like elements are represented by like reference numerals.
Applicant has appreciated that there is an unsolved need to provide a LED connector configuration that enables connecting LED boards to a lighting frame without requiring the use of soldering connections 1, as illustrated in
Turning to
As illustrated in
A base 30 of the connector 10 is capable of being seated against a first side 32, that is, an outside, of a base member of a lighting frame 16 when the connector 10 is connected to the lighting frame 16. That is, the outside of a frame base forms a seat for the connector base 30.
The connector base 30 has a first portion 33 that is a terminal portion 33. The terminal portion 33 of the connector 10 is positioned against an opening 35 in a lighting frame 16 when the connector 10 is connected to a lighting frame 16.
The connector base 30 includes at least a first mounting member 34 for mounting the connector 10 to a lighting frame 16. The mounting member 34 is a first mounting wing 34 extending in a first direction away from the body 20 of the connector 10. The connector base 30 includes a second mounting wing 36 extending away from the connector 10 in a second direction.
A first bottom surface 38 of the first wing 34 and a second bottom surface 40 of the second wing 36 are on a common plane and form a connector base seat 37. The connector base seat 37 is positionable against the first side 32 of the lighting frame 16 for mounting the connector 10 to the lighting frame 16.
As illustrated, the first mounting wing 34 extends further away from a centerline of the base 30 than the second mounting wing 36. From this configuration, the first 34 and second 36 mounting wings, in a plan view thereof, are asymmetrically disposed on the connector 10. As an example, the first mounting wing 34 can be about an eighth of an inch longer, in the plan view, than the second mounting wing 36, when, for example, the tip to tip measurements of the connector is about an inch and a half.
From this configuration, the first 34 and second 36 wings fit into respective first 42 and second 44 asymmetrically disposed tabs on a lighting frame 16. As a result, a predetermined electrical polarity configuration is obtained between the connector 10 and a lighting frame 16 when the connector 10 is positioned on a lighting frame 16.
As can be appreciated by the illustration of the connector 10, a centerline through the first 34 and second 36 mounting wings that extends away from the body 20, forms a straight line that is generally parallel with an axis of the lighting frame 16.
In addition, as illustrated, the major axis of the oval shaped body 20 is perpendicular to the tip to top axis for the mounting wings 34, 36. In addition, the outer opposing tips of the mounting wings are each circular, and each tangentially connects with the major axis of the oval shaped body 20.
The first 22 and second 24 conductive contacts of the connector 10 include respective first 46 and second 48 top portions. The top portions 46, 48 of the connector 10 are electrically connected to respective positive 26 and negative 28 leads. Respective first 50 and second 52 bottom portions of the connector 10 extend to the terminal portion 33 of the base 30 to define respective both first and second fittings and the noted contacts 22, 24. With this configuration, the terminal portion 33 both mechanically receives and electrically connects with respective first 15 and second 18 conductive fasteners. Accordingly, from this configuration, the connector 10 mechanically receives and electrically connects with respective first 17 and second 19 contacts of the lighting board 14. Moreover, from this configuration, the lighting board 14 is mechanically secured to the lighting frame 16.
Additionally, the first 22 and second 24 contacts/connector fittings at the terminal portion 33 are female threaded for receiving male threaded first 15 and second 18 conductive fasteners. For example, the electrical connection between the fittings and the leads can be accomplished via, for example, a threaded, electrically conductive PEM insert, such as model number IBB-632-4, obtainable through, for example, Tower Fasteners Company, Inc., at 1690 North Ocean Avenue, Holtsville, N.Y. 11742-1823. In such an instance, the fasteners can be metallic screws or other desired fastener including a conductive portion adapted to maintain electrical continuity to permit operation of the device in operation.
Moreover, the top 46 of the first contact 22 is fused to the positive lead 26 and the top 48 of the second contact 24 is fused to the negative lead 28.
The terminal portion 33 of the base 30 extends below a surface plane defined by the first 38 and second 40 bottom surfaces of the respective first 34 and second 36 wings. From this configuration, the terminal portion 33 of the base 30 extends into an opening 35 of a lighting frame 16 and is flush with an interior surface 58 of a lighting frame 16, against which a rear surface 59 of a lighting board 14 is disposed when secured to the electrical connector 10.
The connector includes first 62 and second 64 strengthening ribs, serving as gussets. The ribs 62, 64 extend from a first top surface 65 and a second top surface 66 of respective first 34 and second 36 wings to respective first 68 and second 70 portions of a side surface 72 of the central body 20. As illustrated, the first 68 and second 70 portions of the side surface 72 of the central body 20 are opposing sides of the minor axis of the oval shaped central body 20.
An outer end of the first wing 34 includes a first wing eyelet. Additionally, an outer end of the second wing 38 includes a second wing eyelet. The first and second wing eyelets are adapted for being aligned with matching tab eyelets when positioned within respective first 42 and second 44 mounting tabs on a lighting frame 16. From this, the connector 10 is releasably locked to a lighting frame 16. It should be appreciated that while turning the connector 10 in a first direction, such as clockwise, locks the connector 10 against lighting frame tabs, and turning in the opposing direction releases the connector 10.
The body 20 of the connector 10 can be molded plastic or other suitable material. Accordingly, the process of forming the different shapes and ribs is relatively straightforward.
While the connector 10, itself, has been a focus of the present disclosure, a lighting system, as a unit, can include the electrical connector 10 and a lighting frame 16 or lighting box as indicated above. The lighting frame 16, as also indicated above, includes an opening 35 through which the terminal portion 33 of the connector base 30 extends.
The lighting frame 16 also includes the above identified first 42 and second 44 tabs which are asymmetrically disposed about the opening 35, for engaging respective first 34 and second 38 wings, and releasably locking the connector 10 thereto. The first 42 and second 44 tabs can be stamped or punched out of the lighting frame 16, which is typically formed from a metallic sheet.
The first 42 and second 44 tabs are āLā shaped brackets which open in opposing directions about the frame opening 35 as illustrated in
The opening 35 in the lighting frame 16 is circular. With this shape, the terminal portion 33 of the connector is capable of unobstructed twisting therein to facilitate assembly. For example, as illustrated, the terminal portion 33 can have an oval shape. If the opening 35 also had an oval shape, the twist for engaging the wings 34, 26 into respective tabs 42, 44, would be obstructed at the interface between the terminal portion 33 and the opening. By way of further example, the shape of terminal portion could alternatively be round, or any other shape adapted to rotate within circular opening 35.
The first 42 and second 44 tabs have first 82 and second 84 tab eyelets. These tab eyelets 82, 84, as indicated, are aligned with respective wing eyelets enabling releasable locking of the first 34 and second 36 wings against the lighting frame 16, using, e.g., a screw.
According to an embodiment, the lighting frame 16 is thermally conductive, as illustrated in
As indicated, the terminal portion 33 of the base 30 extends below a surface plane defined by the first 38 and second 40 bottom surfaces of the respective first 34 and second 36 wings. From this configuration, as illustrated in
As illustrated in
The system, as a unit, can also include the mentioned first 15 and second 18 conductive fasteners for mechanically and electrically connecting a lighting board 14 to the first 22 and second 24 contacts/fittings. As indicated, the first 15 and second 18 conductive fasteners are screws.
In addition, the system, as a unit, can include a the mentioned lighting board 14, which can be either an LED array or LED point source as illustrated in
It is to be appreciated that the system, as illustrated in
Accordingly, a connector 10 for a lighting board 14 has been disclosed, adapted for receiving electrical energy from a power source 12, and via one or more conductive fasteners, both mechanically connecting a lighting board 14 to a lighting frame 16 and transmitting power from a power source 12 into electrical contacts in a lighting board 14 to power a lighting board 14.
