First Claim
1. A modular vehicular lightbar comprising:
- a support member for supporting a plurality of light modules, said support member comprising an elongated tubular mounting rail having upper and lower portions, said upper and lower rail portions extending the length of said rail and having different cross-sectional shapes;
foot means for affixing said rail to an exterior surface of a vehicle, said foot means comprising at least two spacially displaced mounting feet disposed between said rail and the surface, each of said feet defining an open-sided slot, said rail lower portion being received in said slots and engaged by said feet; and
a plurality of light modules, said modules being positioned along and at least in part supported from said rail, each of said light modules comprising;
a base, said base including at least a bottom wall and first and second opposing side walls, said bottom wall including an external open-sided base channel which extends between said first and second side walls, said base channel being generally complementary in cross-sectional shape to the cross-sectional shape of said upper portion of said mounting rail, said base channel engaging said rail upper portion;
a light transmissive lens affixed to said base, said lens cooperating with said base to define a chamber therebetween; and
at least one light emitter disposed within said chamber, said light emitter being affixed to said base such that at least a portion of the light emitted thereby passes through said lens.

Abstract
A light bar assembly employs a unitary support member in the form of a mounting rail and a plurality of light modules which are configured to engage the mounting rail. In a typical use environment, there will be two basic light module configurations, i.e., a module configured for support from a straight section of the mounting rail and a module configured for support from a curved section of the mounting rail. The individual light modules may each include either or both mechanically driven and electronically controlled warning lights. Each of the light modules comprises a base, a light transmissive dome-shaped lens and one or more light sources, the base and dome lens being interlocked in sealed fashion and defining an enclosure for the light source(s). The base is provided with a channel which is sized and shaped to be in-part complementary to the exterior surface of a portion of the mounting rail. The light modules can be arranged in a variety of configurations on the mounting rail to collectively form an array of light modules.

14. A modular vehicular lightbar comprising:
-
an elongated tubular mounting rail, said rail having an exterior surface defined by upper and lower portions which extend the length of said rail, said upper and lower rail portions having different cross-sectional shapes; and a plurality of light modules positioned on said mounting rail, each of said light modules comprising; a base, said base having a bottom wall and a pair of opposing side walls which extend outwardly from said bottom wall, said base further having a rear wall which extends between said side walls, said bottom wall including an external channel which is proximal to said rear wall, said channel extending longitudinally between said pair of side walls and being substantially parallel to said rear wall, said channel being generally complementary in shape to said upper portion of said exterior surface of said rail, said channel of said base engaging said rail along a portion of the lenath thereof; a light transmissive lens sealingly attached to said base, said lens and said base cooperating to define a chamber therebetween; and at least one light emitter disposed within said chamber, said one light emitter being affixed to said base and being positioned such that at least a portion of the light emitted by said one light emitter passes through said lens. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A modular lightbar comprising:
-
a unitary support for a plurality of light modules, said support including an elongated mounting rail having upper and lower portions, said rail having at least a first linear segment and at least a curvilinear segment extending from an end of said linear segment; foot means for affixing said rail to a surface, said foot means comprising at least two spacially displaced mounting feet disposed between said rail and the surface, each of said feet defining an open-sided slot which is generally complementary in shape to said lower portion of said rail, said rail lower portion being received in said slots and being engaged by said feet; and a plurality of light modules, each of said light modules comprising; a base, said base including a bottom wall and at least first and second opposing side walls, said base further having oppositely disposed front and rear sides which extend between said side walls, said bottom wall including an external open-sided base channel which extends longitudinally between said first and second side walls, said base channel being defined by plural surfaces and having a cross-sectional shape which is, at least in part, generally complementary to the cross-sectional shape of said upper portion of said mounting rail, said base channel engaging said rail upper portion to thereby at least in part support said module from said mounting rail, said front and rear sides of said base extending generally parallelly to said base channel, said base channel of at least one of said light modules having a curvilinear configuration in the longitudinal direction, said curvilinear configuration matching at least a portion of said curvilinear rail segment whereby said one light module may be mounted on said curvilinear rail segment; a light transmissive lens affixed to said base, said lens having side walls and front and rear sides, said lens walls and sides being shaped to cooperate with respective of said base walls and sides to define a chamber between said base and lens; and at least one light emitter disposed within said chamber, said one light emitter being mounted on said base and being positioned such that at least a portion of the light emitted by said one emitter will pass through said lens. - View Dependent Claims (24, 25)
