Modular light bar

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.

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.

A modular vehicular lightbar comprising:

• a generally U-shaped light module support, said support comprising an elongated tubular mounting rail, said rail having at least a first linear segment and a pair of curvilinear segments, said curvilinear segments extending from opposite ends of said linear segment, said rail having upper and lower portions which extend along said segments between opposite ends of said U-shaped support;
• 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 size and shape to said upper portion of at least a part of one of said segments of said rail, said channel of said base engaging said rail along a portion of the length of said rail which is sized and shaped to engage said channel;
• 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.
