BEACON WITH ILLUMINATED LEDS ARRAY BOARDS CONNECTED

Description

FIELD OF THE INVENTION

The present invention generally relates to flashing light beacons for use on vehicles.

BACKGROUND OF THE INVENTION

Beacons provide flashing light signals for vehicles such as fire trucks and police cars. Beacons typically have a plurality of lights (e.g., LEDs) mounted inside a lens or other outer cover. The lights are typically connected to a controller that controls operation of the lights. The controller can turn off all the lights for periods when no signal lighting is needed. Further, when signal lighting is desired, the controller can turn the lights on and off (e.g., in a sequence in which some of the lights are on and others may be off during a particular instant) in various patterns to create various signal lighting effects. It can be complicated to connect each of the lights to the controller during assembly of a beacon because the lights are typically positioned so they collectively form an annular configuration and face radially outward in different directions and this complicates the assembly.

SUMMARY OF THE INVENTION

One aspect of the invention is a beacon for a vehicle. The beacon has a base configured for mounting on the vehicle. A plurality of LED arrays are mounted on the base. Each LED array has an LED array circuit board extending upwardly from the base, a plurality of LEDs mounted on the circuit board, and an electrical connector supported by the LED array circuit board and connected to the LEDs. The LED arrays are being arranged to direct light signals outward in multiple different radial directions. The beacon has a common circuit board connected to each of the plurality of LED arrays. The common circuit board includes a plurality of electrical connectors supported by the common circuit board and connected to electrical components on the common circuit board. The electrical connectors on the common circuit board are connected to the electrical connectors of the LED arrays so the LEDs are in electrical connection with the electrical components on the common circuit board. The electrical connectors of the LED circuit boards and the common circuit board are substantially identical to one another.

Each LED array has an LED array circuit board extending upwardly from the base, and a plurality of LEDs mounted on the circuit board, and an electrical connector supported by the LED array circuit board and connected to the LEDs. The LED arrays are arranged to direct light signals outward in multiple different radial directions. The beacon has a common circuit board connected to each of the plurality of LED arrays. The common circuit board has a plurality of electrical connectors supported by the common circuit board and connected to electrical components on the common circuit board. The electrical connectors on the common circuit board are connected to the electrical connectors of the LED arrays to form mated connector pairs so the LEDs are in electrical connection with the electrical components on the common circuit board. Each mated connector pair includes a spade terminal on one of the electrical connectors of the mated electrical pair received in a socket of the other electrical connector of the mated electrical pair. The spade terminal extends into the socket from a side of the socket.

Another aspect of the invention is a method of connecting an LED array of a signal lighting beacon to a common circuit board of the signal lighting beacon. The method includes inserting a spade terminal of an electrical connector on one of the LED array and common circuit board into a socket of another electrical connector on the other of the LED array and common circuit board, wherein inserting the spade into the socket comprises inserting the spade terminal into the socket from a side of the socket.

Other objects and features will be in part apparent and in part pointed out hereinafter.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the figures, a beacon 100 is illustrated for a vehicle such as the vehicle 200 as shown in FIG. 12. The vehicle of FIG. 12 is illustrated as a fire truck. However, it is contemplated that beacon 100 may be used with any vehicle within the scope of the invention. For example, any vehicle such as an ambulance, a police vehicle, a fire vehicle, an emergency vehicle, or a maintenance vehicle may use the beacon 100. As another example, any vehicle in which a user desires to have scene lighting, either flashing or steady burn, may use the beacon 100. Herein, the vehicle 200 may be referred to as a fire truck but it should be understood that vehicle 200 may be any vehicle.

As illustrated, the beacon 100 suitably has a circular base 102 configured for horizontal mounting on the fire truck 200. For example, the base 102 may have a socket 104 (FIG. 5) for engaging a vertical support post (not shown) of the fire truck 200. Referring to FIG. 2, the beacon 100 includes a plurality of LED arrays 110 mounted on the base 102 for providing light signals. In the illustrated embodiment, there are twelve LED arrays 110, but this number can vary within the scope of the invention. In the illustrated embodiment, the LED arrays 110 are all substantially identical so a detailed description of one will suffice for them all. However, it is understood that one or more of the LED arrays can be different from the other LED arrays within the scope of the invention.

As illustrated in FIGS. 5, 6, and 8 each LED array 110 includes a plurality of LEDs 112 mounted on an LED circuit board 114. In the illustrated embodiment, the LED circuit board 114 has a rectangular shape and is substantially planar. The LEDs 112 are suitably arranged in a linear pattern (e.g., in a substantially vertical line) along the length of the LED circuit board 114, although the number and arrangement of the LEDs can vary within the broad scope of the invention. In the illustrated embodiment, for example, there are three LEDs 112 mounted along the central longitudinal axis of the LED circuit board 114. Each LED 112 is suitably covered by a lens 116 secured to the LED circuit board 114. Accordingly, the LED array 110 has a linear configuration in which the LEDs 112 and the corresponding lenses 116 extend substantially the entire length of the LED circuit board 114. In one example, the lenses 116 are configured to focus the light from the respective LED 112 within a substantially horizontal plane. Those skilled in the art will be familiar with a variety of commercially available lenses that can be used to focus, disperse, or otherwise direct the light from the LEDs in a desired manner.

Each LED array 110 is connected to and vertically supported by the base 102. Referring to FIGS. 11A-11C, each LED array 110 is suitably secured to a bracket 120 that is itself secured to the circular base 102. For example, screws 126 or other suitable fasteners can be used to secure the brackets 120 to the base 102 and to secure the LED arrays 110 to the brackets. As illustrated in FIG. 11A, each bracket 120 has a foot 122 adapted to sit on the base 102 and an upright portion 124 adapted to extend upward from the foot and the base. The LED arrays 110 are secured to the upright portion 124 of the bracket 120 so the brackets hold the LED arrays in an upright orientation relative to the circular base 102. In the illustrated embodiment, the upright portion 124 of each bracket 120 has three different faces 132, each of which can support a single LED array 110. Each of the faces 132 is oriented in a different direction so the bracket 120 can support multiple LED arrays 110 in a configuration in which each LED array is pointed in a different radial direction. The use of brackets 120 that can support more than one LED array 110 can expedite assembly because fewer steps are required to secure all the brackets to the base 102. Although the beacon 100 illustrated in FIGS. 1-11C has four brackets 120 that are each adapted to support three LED arrays 110, it is understood that the number of LED arrays that are supported by a single bracket can vary within the scope of the invention. Further, it is possible that some of the brackets may support a different number of LED arrays than other brackets within the scope of the invention.

The LED arrays 110 are suitably arranged in a cylindrical configuration in which each LED array has an upright orientation and the LEDs 112 are positioned to direct light generally radially outward, as shown in FIG. 6. The arrangement of the LED arrays 110 allows for providing substantially 360 degrees of horizontal lighting relative to the fire truck 200 or other vehicle.

The LED circuit boards 114 of the LED arrays 110 are electrically connected to a common central circuit board 130 via connectors 118, 128. Referring to FIGS. 7-10, the common circuit board 130 and the LED circuit boards 114 are single-sided boards, meaning all electrical connections and components are on one side of the board. In the case of the LED circuit boards 114, the electrical components and connections are suitably on the side of the board facing radially outward. In the case of the common central circuit board 130, all electrical components 152 and connections are suitably on the side of the board facing down toward the circular base 102. Although use of single-sided circuit boards 114, 130 constrains all electrical components and connections to be on only one side of the board, they can be substantially cheaper to manufacture than double-sided circuit boards.

Because the single-sided circuit boards 114, 130 require all electrical connections to be on a particular side of the board, electrical connectors 118 for the LED arrays 110 are on the side of the respective boards facing radially outward. Likewise, the electrical connectors 128 on the common central board 130 are on the side of the board facing down toward the circular base 102. In the illustrated embodiment, the electrical connectors 118 on the LED array circuit boards 114 are substantially identical to the electrical connectors 128 on the common central board 130. The electrical connectors could be different within the scope of the invention. However, the use of the same type of connector 118, 128 for each board 114, 130 simplifies the inventory requirements for a manufacturing process that makes the beacon 100.

Referring to FIGS. 9 and 10, each of the connectors 118, 128 in this embodiment includes a plurality of spade terminals 142 and/or electrical sockets 144 for receiving a corresponding spade terminal on the other connector. For example, a spade terminal 142 is suitably a substantially flat planar piece of electrically conductive material. Generally, a socket 144 is an electrically conductive structure adapted to make an electrical connection with a spade terminal 142 as the spade terminal is inserted into space defined by the socket. For example, the sockets 144 are suitably formed by two generally flat opposing plates 144a, 144b of electrically conductive material spaced apart from one another by a gap for receiving a spade terminal. The edges of the socket plates 144a, 144b are suitably angled away from the opposing plate of the socket 144 to facilitate insertion of a spade terminal 142 into the gap between the plates notwithstanding minor misalignment of the spade terminal that may exist. The spade terminals 142 and the plates 144a, 144b of the sockets 144 suitably extend from a housing 148 of the connectors 118, 128. As used herein, the “base” of a socket 144 refers to the part of the socket adjoining the connector housing 148, the “top” of the socket refers to the end of the socket opposite the connector housing, and the “side” of the socket refers to either of the opposite edge margins of the socket extending between the base of the socket and the top of the socket. As illustrated, each connector 118, 128 includes two spade connectors 142 and two sockets 144 arranged in an alternating series. It is understood that any spade 142 on either connector 118, 128 can be replaced by a socket 144 as long as a corresponding socket on the mating connector is replaced with a spade.

Referring to FIGS. 9 and 10, when the connectors 118, 128 are connected to one another, they are offset relative to one another by one spade/socket position so the spades 142 are aligned with sockets 144 and vice-versa. The use of single-sided boards 114, 130 constrains the way the connectors 118, 128 can be mounted thereon. Consequently, an attempt to connect the identical connectors 118, 128 to one another in a non-offset alignment would result in an attempt to connect the spades 142 to other spades and connect the sockets 144 to other sockets. Accordingly, the mating connectors 118, 128 are laterally offset one position so the spades 142 are aligned with the sockets 144 and vice-versa. Referring to FIG. 10, the centers 156 of the connectors 118 of the LED arrays 110 are suitably offset (e.g., to the right in FIG. 10) from the central longitudinal axis 152 of the LED array 110. Likewise, the centers 156 of the connectors 128 on the common central board 130 are suitably offset (e.g., to the left in FIG. 10) of a midpoint 154 of a side 158 edge of the common board. Although both connectors 118, 128 are offset from a central position on their respective boards 114, 130 in the illustrated embodiment, it is understood the offsetting of the connectors be achieved by offsetting only one connector of each mating pair from its central position on its respective board. It is also understood that the entire LED array 110 can be offset relative to the mating connector 128 on the central board 130 instead of just the connector 118 within the scope of the invention. Moreover, the need to offset the connectors from one another can be avoided (e.g., by using two different types of connectors instead of just a single type of connector) within the scope of the invention.

One consequence of the offset connectors 118, 128 is that the connectors do not make full use of their potential connectivity. For example, the connectors 118, 128 in the illustrated embodiment have the capacity to make four electrical connections, but the way they are connected in the beacon 100 results in only three electrical connections. Three electrical connections are all that is needed in this embodiment, in which each LED array 110 has three LEDs 112. Moreover, connectors that are designed to make two or four connections are readily available from various commercial suppliers, while connectors that are designed to make exactly three electrical connections when fully connected are not as readily available, particularly not at the same relatively low cost as the four-pin connectors 118, 128 used in the illustrated beacon 100.

The connectors 118, 128 are suitably configured so they can be connected to one other by extending the spades 142 of one connector into the sockets 144 of the other connector from the sides of the sockets. The connectors 118, 128 are also suitably configured so the connectors can be rotated relative to one another while they are connected to one another.

In the illustrated embodiment, for example, a plurality of electrical barriers 146 made of an electrically-insulting material are positioned between each of the adjacent spades 142 and sockets 144. The barriers 146 are suitably configured so they are effective at maintaining electrical separation between adjacent spades 142 and sockets 144 but so they do not constrain the direction of insertion of spades into the sockets to exclude insertion of the spades into the sockets from the side. In the illustrated embodiment, for example, the barriers 146 are substantially planar walls extending from a connection to the connector housing 148 along a single edge of the barrier. Thus, in addition to allowing for insertion of a spade 142 into a socket 144 in a direction from the open end of the socket toward the connector housing 148, the barriers 146 permit insertion of the spades into the sockets from a side direction (e.g., in a direction generally parallel to the surface of the connector housing adjacent the sockets).

As illustrated in FIG. 8, for example, the connectors 118, 128 can be connected to one another by moving the common central board 130 and LED array 110 laterally toward one another as indicated by arrows A1 while the connectors 118, 128 are oriented generally orthogonally to one another. This results in the spades 142 of the connector 128 on the common board 130 being inserted into the sockets 144 of the connector 118 on the LED array 110 from the sides of the sockets, while the spades on the connector of the LED array are inserted into the sockets of the connector on the common board from the top end of the socket but with the spades being in a sidewise orientation relative to the sockets so that once the connectors are connected all of the spades of both connectors extend into their respective sockets from the side. As illustrated in FIG. 11C, the connectors 118, 128 can also be connected to one another by moving the common board 130 down relative to the LED array 110 while the connectors are oriented substantially orthogonally to one another, as indicated by the arrow A2. This results in the spades 142 of the connectors 118 on the LED arrays 110 being inserted into the sockets 144 of the connectors 128 on the common central board 130 from the sides of the sockets, while the spades on the connectors of the common central board are inserted into the sockets of the connectors on the LED arrays from the top end of the socket but with the spades being in a sidewise orientation relative to the sockets so that once the connectors are connected all of the spades of both connectors extend into their respective sockets from the side.

Moreover, once the spades 142 are received in the sockets 144, the barriers 146 do not obstruct rotation of the spades within the sockets. For example, as illustrated in FIG. 9, the barriers 146 in the illustrated embodiment are configured so the spade terminals 142 can be rotated in either direction on an axis 150 generally perpendicular to the major surfaces of the spades in the direction of arrow A3 while the spades remain in their sockets 144 by rotating the connectors 118, 128 relative to one another after they are connected. This allows the LED array 110, including the LED board 114, to be rotated relative to the common central board 130 after the connectors 118, 128 are connected without disconnecting the connectors and without the need to reconnect the connectors after the rotation.

It is understood the configuration of spades 142, sockets 144, and barriers 146 illustrated in the drawings is one suitable configuration that allows insertion of the spades into the sockets from the side and allows rotation of the connectors 118, 128 while they remain connected to one another and that there are other suitable configurations that could be used instead within the broad scope of the invention.

The common central circuit board 130 is suitably fastened to the brackets 120 to secure it to the LED arrays 110 and maintain electrical connection between the connectors 118, 128, as well as retain it in position relative to the base 102 to which the brackets are secured. For example, the brackets 120 in the illustrated embodiment each have a horizontal mounting tab 160 at their upper end. The common central circuit board 130 is suitably secured to the tabs 160 of the brackets 120 by screws 162 or other suitable fasteners, as illustrated in FIG. 11C.

The common central circuit board 130 has various electrical components 168 mounted to its underside (FIG. 7) for conditioning various input signals to a central processor on the common circuit board and/or for conditioning various output signals from the processor. The components 168 of the common circuit board 130 also suitably include a power supply which is connectable to a power source (not shown) such as a battery of the fire truck 200, through the central socket 104 in the base 102 of the beacon 100. The processor is configured to selectively and intermittently energize the LEDs 112 in the LED arrays 110 and coordinate activities of the LEDs in the LED arrays to achieve various different lighting effects. In one form, the processor may be a flash based, CMOS microcontroller. However any processor or controller may be used.

A cylindrical lens cover 132 (FIG. 1) which may be transparent or translucent covers the common central circuit board and the LED arrays 110 and engages the base 102 to create a water-tight unit. The lens cover 132 can include ridges, optic flutes, facets, and/or frosting if desired to make light from the LEDs more diffuse.

FIGS. 11A-11C illustrate one embodiment of a method manufacturing the beacon 100. The brackets 120 are secured to the base 102, as illustrated in FIG. 11A. In FIG. 11A, the brackets 120 are illustrated as being secured to the base 102 before the LED arrays 110 are secured to the brackets. However, it is noted some or all of the LED arrays 110 can already be secured to the brackets 120 when the brackets are secured to the base if desired. When all of the brackets 120 are secured to the base (FIG. 11B), they form a generally cylindrical support structure that is adapted to hold the LED arrays 110 in a corresponding upright annular configuration. If the LED arrays 110 have not already been secured to the brackets 120, they are suitably secured to the brackets now in preparation for assembly of the common central circuit board 130. Once all of the LED arrays 110 are secured to the brackets 120, the common central board 130 is moved down axially in the vertical direction as indicated by arrow A2 on FIG. 11C to connect the connectors 128 thereon to the corresponding connectors 118 on the LED circuit boards 114 of the LED arrays 110. When the common board 130 is connected to the LED arrays 110 this way all of the connections between the various LED array connectors 118 and the corresponding connectors 128 on the common board 130 can be made substantially simultaneously in a single step. Then the common central circuit board 130 is secured to the brackets 120 using the screws or other suitable fasteners.

Alternatively, one or more of the LED arrays 110 can be added to the assembly after the common central circuit board 130 has been secured to the brackets 120. This can be accomplished by moving the LED array 110 radially inward until the spades 142 and sockets 144 on the connectors 118, 128 engage one another and thereby establish electrical connection between the LED circuit board 114 and the common central circuit board 130. For example, the LED array 110 can be in a vertical orientation (such that the LED circuit board 114 is generally parallel to the mounting portion 124 of the corresponding bracket) as the LED array is moved radially inward to connector the connectors 118, 128. As another example, the LED array 110 is not in a vertical orientation (e.g., it is in a substantially horizontal orientation) as it is moved radially inward to connect the connectors 118, 128 and after the spades 142 are received in the sockets 144, the LED array 110 is pivoted about the pivot axis 150 generally aligned with the spades and sockets to rotate the LED array into the vertical orientation. Then the LED array 110 is secured to the bracket 120 using screws or other suitable fasteners.

In either case, at least one step of the assembly results in arrangement of corresponding connectors 118, 128 on the LED circuit board 114 and the common central circuit board 130 so the connectors are electrically connected to one another in a generally orthogonal orientation (e.g., perpendicular to one another). The ability to connect the connectors 118, 128 to one another so the spades 142 extend into the sockets 144 from the side provides significant flexibility in the manner of making electrical connections, allows all the connectors 118, 128 for all of the LED arrays 110 to be connected simultaneously in a single step if desired, facilitates a simple yet reliable electrical connection between two single-sided circuit boards 114, 130 that are angularly disposed relative to one another, allows easy removal and/or replacement of one or more LED arrays 110 for repair or maintenance of the beacon 100, and provides other advantages.
