[0063] FIG. 1 shows a perspective view of an embodiment of a housing (100) for connecting a light bar (200 as shown in FIG. 3) to a vehicle (10). As shown in FIG. 1, the housing may comprise a front surface (110), a first side surface (120), a second side surface (130) which is opposite of the first side surface, and a top surface (140). The front surface, first side surface, second side surface, and top surface will define a generally hollow interior (150 as shown in FIG. 3). In the embodiment shown in FIG. 1, the housing connects the light bar to a roof top surface (15) of the vehicle. When the housing connects the light bar to a roof top surface (15) of a vehicle (10) as shown in FIG. 1, it is preferred that the top surface (140) of the housing does not extend past the roof top surface as shown in FIG. 1. The housing may connect to the surface of the vehicle along at least a portion of at least one of the front surface, the first side surface, the second side surface, the first bracket (160 as shown in FIG. 3), and/or the second bracket (170 as shown in FIG. 3).

[0064] FIG. 2 illustrates a perspective view of an alternative embodiment of a housing (100) for connecting a light bar (200 as shown in FIG. 3) to a vehicle (10). Like the embodiment shown in FIG. 1, the housing shown in the embodiment in FIG. 2 may comprise a front surface (110), a first side surface (120), a second side surface (130) which is opposite the first side surface, and a top surface (140). The front surface, first side surface, second side surface, and top surface define a generally hollow interior (150 as shown in FIG. 3). In the embodiment shown in FIG. 2, the housing connects the light bar to a bumper (17) of the vehicle. Like in embodiments which attach to the vehicle roof, the housing may connect to the surface of the vehicle along at least a portion of at least one of the front surface, the first side surface, the second side surface, the first bracket (160 as shown in FIG. 3), and/or the second bracket (170 as shown in FIG. 3).

[0065] FIG. 3 shows a perspective view of an embodiment of a housing (100) for connecting a light bar (200) to a vehicle (10) with the light bar and the housing separated from one another while FIG. 4 shows the same embodiment in assembled form with the light bar and the housing connected to one another. As shown in FIG. 3, the front surface (110) of the housing may comprise a lighting aperture (115). The lighting aperture will pass the entire way through the front surface. While the lighting aperture may come in many shapes and sizes, the lighting aperture will preferably be sized and shaped to correspond with a front face (230) of the light bar such that light projected from the light bar may project outwardly from the housing. Preferably, the lighting aperture will be sized and shaped so that less than 10% of the light projected by the light bar is blocked by the housing with less than 5% of the light projected by the light bar being blocked by the housing being more preferred, less than 1% of the light projected by the light bar being blocked by the housing being still more preferred and less than 0.1% of the light projected by the light bar being blocked by the housing being most preferred.

[0066] In some embodiments, the lighting aperture (115) may comprise a lens located within at least a portion of the lighting aperture. When present, the lens may be fabricated of any number of partially or fully transparent materials including glass, polymer (i.e. —polycarbonate, polyester), and the like. The lens—when present—may be attached to the lighting aperture by any number of mechanisms including adhesives, fasteners (i.e. —screws, bolts, rivets, and the like), a friction fit between the lens and one or more edges of the lighting aperture, and combinations thereof.

[0067] Also shown in FIG. 3 is the hollow interior (150) of the housing (100). As shown in FIG. 3, the hollow interior may be defined as the space encompassed by at least the front surface (110), the first side surface (120), the second side surface (130), and the top surface (140). It is within the hollow interior that the light bar (200) resides when the housing is connected to the vehicle (10 as shown in FIG. 1 and FIG. 2). In some embodiments, the hollow interior may be further encompassed by an optional bottom surface (not shown) which spans between the front surface, the first side surface, the top surface, and the second side surface. In certain embodiments, the hollow interior may be encompassed by an optional back surface (not shown) which spans between the optional bottom surface, the first side surface, the front surface, and the second side surface.

[0068] Further shown in FIG. 3 is a first bracket (160) and a second bracket (170). As shown in FIG. 3, each of the first bracket and the second bracket may be located within the hollow interior (150) of the housing. The first bracket—as shown in FIG. 4—may be configured to connect a first interior face (151) of the housing to a first side (210) of the light bar. Similarly, the second bracket may be configured to connect a second interior face (152) of the housing to a second side (220) of the light bar as shown in FIG. 4.

[0069] While the first bracket (160) and the second bracket (170) may come in many forms, one preferred form is an “L” shaped bracket such as shown in FIG. 3. When used, the “L” shaped bracket will comprise a first bracket surface (162/172) which connects to the corresponding side of the light bar (200) as shown in FIG. 4, and a second bracket surface (163/173) which may be used to connect the housing to a surface of the vehicle.

[0070] The first bracket (160) may connect to the first side (210) of the light bar (200) by passing a first fastener (211) through a first hole (164) in the first bracket and into a corresponding hole in the first side of the light bar. Non-limiting examples of such fasteners include a bolt, a screw, a rivet, a clip, and the like. When the first bracket is an “L” shaped bracket, the first hole will pass through the first bracket surface (162) of the first bracket.

[0071] Similarly, the second bracket (170) may connect to the second side (220) of the light bar (200) by passing a second fastener (221) through a second hole (174) in the second bracket and into a corresponding hole in the second side of the light bar. Non-limiting examples of such fasteners include a bolt, a screw, a rivet, a clip, and the like. When the second bracket is an “L” shaped bracket, the second hole will pass through the first bracket surface (172) of the second bracket.

[0072] In some instances, the first bracket (160) and/or the second bracket (170) may be integrally connected to the housing (100) within the hollow interior (150) as shown in FIG. 3. In such embodiments, the first bracket will preferably be integrally connected to the housing within the hollow interior along the first side surface (120). Similarly, the second bracket will preferably be integrally connected to the housing within the hollow interior along the second side surface (130). The first bracket and/or the second bracket may be integrally connected to the housing by any number of methods including manufacturing the housing and the brackets of a single integral piece of material (i.e. —by injection molding, casting, milling, 3D printing, or the like) or by manufacturing the housing and the brackets of separate pieces of material and permanently attaching the brackets to the housing (i.e. —by welding or the like).

[0073] In other embodiments, the first bracket (160) and/or the second bracket (170) may be removably connected to the housing (100) within the hollow interior (150). One such embodiment is shown in FIG. 7. In such embodiments, the first bracket will preferably be removably connected to the housing within the hollow interior along the first side surface (120). Similarly, the second bracket will preferably be removably connected to the housing within the hollow interior along the second side surface (130). In some such embodiments, the bracket(s) may be configured to frictionally engage with the housing such that the brackets “snap” into the housing (i.e. —using a tongue and groove connection or the like). In other embodiments, the bracket(s) may be configured to connect to the housing by a fastener such as a bolt (with or without a nut), a screw, a rivet, a clip, a clamp, or the like.

[0074] FIG. 5 shows a bottom view of one embodiment of a housing (100). As shown in FIG. 5, the brackets (160 and 170) connect to the housing within the hollow interior of the housing. In the embodiment shown in FIG. 5, the brackets are “L” shaped brackets with a first portion of the bracket connecting to the top surface (140 as shown in FIG. 3) of the housing and a second portion of the bracket connecting to the front surface (110 as shown in FIG. 3) of the housing. The fasteners (211 and 221) then pass through the brackets to connect to the sides of the light bar to the housing as shown in FIG. 5.

[0075] The housing (100) may be configured to connect to a surface of a vehicle (10)— which may be either a roof top surface (15) of a vehicle or a bumper (17) surface of a vehicle in the embodiments as shown in the Figures. One of ordinary skill will also recognize that the surface of the vehicle may also be a front bumper surface, a hood surface, a grill surface, a rear bumper surface, or a trunk lid surface. For example, the connections may be between a first bracket (160) and a first bumper surface of a bumper (17) and/or a second bracket (170) and a second bumper surface of the bumper.

[0076] As shown in the Figures, the first bracket surface (162) of the first bracket (160) is connected to the first side (210) of the light bar (200) by the first fastener (211). The second bracket surface (163) of the first bracket is then connected to a first surface of the vehicle (i.e. —a first roof surface or a first bumper surface). The second bracket surface of the first bracket may be connected to the first surface of the vehicle by a fastener—such as a bolt, a screw, a rivet, a clip, or the like. In addition to or instead of a fastener, the second bracket surface may be connected to the first surface of the vehicle by way of an adhesive or a tape. In other embodiments the second bracket surface of the first bracket may not connect to the first vehicle surface at all. Instead, one or more of at least a portion of the front surface (110), at least a portion of the first side surface (120), at least a portion of the second side surface (130), at least a portion of the top surface (140), at least a portion of the (optional) back surface, and/or at least a portion of the (optional) bottom surface may be used to connect to a surface of the vehicle.

[0077] FIG. 6 shows a close-up view of an embodiment of a bracket—which in this case is labelled as the first bracket (160) but may also be the second bracket (170). As shown in FIG. 6, the first bracket is in the form of an “L” shaped bracket integrally connected within the hollow interior of the housing (100). The first bracket surface (162) of the first bracket in the embodiment shown in FIG. 6 is integrally connected to and extends downwardly from the interior face of the top surface (140) of the housing. The second bracket surface (163) of the first bracket then extends substantially perpendicular from (or perpendicular from) the first bracket surface with the second bracket surface integrally connected to and extending from the interior face of the first side surface (120).

[0078] FIG. 7 shows one alternative embodiment of the housing (100) in which one or more of the brackets is removably connected to the housing within the hollow interior. As shown in FIG. 7, the bracket—which in this case is labelled as the first bracket (160) but may also be the second bracket (170)— is in the form of an “L” shaped bracket. The first bracket surface (162) of the first bracket in FIG. 7 is connected to the first side (210) of the light bar (200) by a fastener. The second bracket surface (163) of the first bracket is then connected to a surface of the vehicle—which in this case is a bumper surface (17), but may also be a roof top surface, a grill surface, a rear bumper surface, or a trunk lid surface. The connection between the second bracket surface and the surface of the vehicle may be by way of a fastener or by an adhesive or a tape. The housing then fits over the light bar and the brackets.

[0079] In the embodiment shown in FIG. 7 the housing (100) may be connected to one or both of the vehicle surface—roof top surface, front bumper surface, grill surface, rear bumper surface, trunk lid surface—the light bar (200) and/or the bracket(s) by many different mechanisms. One such mechanism is a friction fit between at least a portion of the housing on one hand and the vehicle surface, light bar, and/or bracket(s) such that the housing “snaps” onto the vehicle surface, light bar, and/or brackets. Another mechanism may involve the use of an adhesive or tape applied between one or more of the housing surfaces—front surface, first side surface, second side surface, top surface, optional bottom surface, and/or optional back surface—on one hand and the vehicle surface, light bar, and/or bracket(s) on the other hand. Another mechanism may involve the use of one or more secondary bracket(s) which connect between an interior face of one or more of the housing surfaces and a surface of the vehicle. When used, the secondary bracket(s) may connect to the interior face of the housing surface and/or the surface of the vehicle in a number of manners including by way of fastener(s), adhesive(s), tape(s), and/or by a friction fit.

[0080] In preferred embodiments the housing may be contoured on the surface(s) which is/are to connect to the vehicle to substantially match the shape of the vehicle surface to which the housing will be connected. That is to say that at least a bottom edge of each of the front surface, the first side surface, the second side surface, and the top surface may be contoured to substantially match the exterior surface profile of the vehicle surface—roof surface, front bumper surface, grill surface, rear bumper surface, trunk lid surface—to which the housing will be mounted. In embodiments where the housing comprises an optional back surface, a bottom edge of the optional back surface may also be contoured to substantially match the exterior surface profile of the vehicle surface to which the housing will be mounted. When the housing comprises an optional bottom surface, an exterior face of the bottom surface may also be contoured to substantially match the exterior surface profile of the vehicle surface to which the housing will be mounted. Contouring the housing surface(s) to substantially match the exterior profile of the vehicle surface to which the housing will be mounted may be particularly beneficial when the housing is to be connected to the vehicle by an adhesive applied between the housing surface(s) and the vehicle surface(s).

[0081] FIG. 8 and FIG. 9 show additional details of one embodiment of a light bar (200). In general, a light bar may comprise an extruded aluminum containment structure (240). A circuit board (250) may be attached to the extruded aluminum containment structure with a plurality of light-emitting diodes (LEDs) (252) mounted to the circuit board. A cable assembly (254) is attached to and extends from the circuit board for connection to the vehicle's power system (battery and switches—not shown). The front face (230) of the extruded aluminum containment structure will include an opening (235) which allows the LEDs to project light outwardly from the light bar upon receiving electricity from the vehicle's power system. This opening may include a lens (237) made of glass, polycarbonate, or other transparent material which seals the light bar within the extruded aluminum containment structure to prevent water and road debris from entering the light bar and damaging the electronics thereof.

[0082] Optionally, the light bar (200) may include optics and/or reflector cones. The optics—when present—may change the appearance of the light emitted from one or more of the LED's (252). When utilized—the reflector cones may focus the light emitted from one or more of the LED's. In some embodiments, the reflector cones may include a plastic (transparent polycarbonate, transparent polyester, etc.) lens which covers a portion of the reflector cone.

[0083] The housing disclosed herein allows for mounting of a light bar to a vehicle in a manner which is aesthetically pleasing with all hardware or fasteners concealed by the surfaces of the housing. Additionally, unlike the prior art solutions, the embodiments disclosed herein reduce the amount of hardware used for connecting the light bar to the vehicle. The embodiments disclosed herein further allow the light bar to be connected to the vehicle in a manner which reduces resulting disruptions in the aerodynamic profile of the vehicle.
