Warning Light Assembly
First Claim
1. A warning light for attachment to a vehicle comprising:
- a thermally conductive longitudinally extending base having a pair of generally parallel longitudinal edges, said base defining a pair of longitudinally extending light head retention pockets adjacent to and oriented laterally away from said edges, a pair of longitudinally extending ribs spaced laterally inwardly of said pockets projecting perpendicularly from said base and terminating in a distal ridge, each rib having a retention lip projecting laterally toward said retention pocket at a point intermediate said base and said distal ridge and defining a retention channel oriented toward said base;
a plurality of brackets constructed of thermally conductive material having a generally planar bracket first portion and a generally planar bracket second portion oriented generally perpendicular to said bracket first portion;
a plurality of light head retention shoes corresponding in number with said brackets, each shoe having a sole configured to engage said retention pocket of said base and to maintain said bracket first portion in thermally conductive contact with said base, a rib engaging portion laterally opposite said foot having a plurality of fingers configured to engage said distal ridge and a flexible retention member configured to reversibly engage said retention channel, and a brace having a web and opposed sidewalls projecting generally perpendicularly from said web and extending angularly between said rib engaging portion and said sole, thereby forming a rigid structure;
a plurality of light emitting diodes mounted in thermally conductive contact to said bracket second portion;
at least one light-transmissive dome secured to said longitudinal edges.

Abstract
A warning light for attachment to a vehicle comprising a thermally conductive longitudinally extending base, a plurality of light head mount assemblies, a plurality of LED warning light assemblies, and a plurality of electronic control circuits. Said base has a pair of generally parallel longitudinal edges and a pair of ribs projecting perpendicularly from said base. Said light head mount assemblies comprise a bracket and a light head retention shoe. Said bracket has a generally planar bracket first portion and a generally planar bracket second portion oriented perpendicular to said first portion. Said light head shoe has a sole configured to engage said bracket first portion, a rib engaging portion, and a brace extending angularly therebetween. Said LED assemblies are mounted on said bracket second portion. Said dome has a main body portion, sidewalls configured to engage said edges, and end walls.

11. A warning light for attachment to a vehicle comprising:
-
a thermally conductive longitudinally extending base having a pair of generally parallel longitudinal edges, a pair of longitudinally extending ribs spaced laterally inwardly of said longitudinal edges and projecting generally perpendicularly from said base terminating in a distal ridge; wherein said pair of ribs define a center channel sized to receive at least one PC board and a plurality of arch-shaped bridges, each of said bridges having laterally opposed pairs of feet, a snap fit connector extending away from said bridge and configured to reversibly mate with a longitudinal fixation notch defined on at least one of said ribs, said bridge having a PC board retention member comprising a snap working cooperatively with a nub configured to engage one of a plurality of locator holes defined on longitudinally opposed ends of said control PC board to secure said control PC board within said center channel intermediate said bridges; a plurality of brackets constructed of thermally conductive material having a generally planar bracket first portion and a generally planar bracket second portion oriented generally perpendicular to said bracket first portion; a plurality of light head retention shoes corresponding in number with said brackets, each light head shoe having a sole configured to maintain said bracket first portion in thermally conductive contact with said base, and a brace having a web and opposed sidewalls projecting generally perpendicularly from said main body, wherein said shoes are operatively retained intermediate one of said ribs and one of said longitudinal edges; a plurality of light emitting diodes mounted in thermally conductive contact to said bracket second portion; at least one light-transmissive dome secured to said longitudinal edges. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A warning light for attachment to a vehicle comprising:
-
a generally planar thermally conductive longitudinally extending base having a pair of generally parallel longitudinal edges and a pair of longitudinally opposed ends; at least one light transmissive dome having a generally planar main body portion oriented generally parallel to said base, longitudinally opposed inner and outer ends, and sidewalls contiguous with and extending generally perpendicularly from said generally planar main body portion terminating in a bottom edge, said main body portion defining a shallow longitudinally extending dome channel, wherein said outer terminal end has an end wall contiguous with and extending generally perpendicularly from said main body portion and terminating in a bottom edge, said end wall oriented contiguous with and generally transverse to said sidewalls; a longitudinally extending panel sized to be received in said dome channel; wherein said longitudinal edges define a longitudinally extending dome-securing channel configured to receive said bottom edge of said sidewalls such that said light transmissive dome is longitudinally slideable along said base between said inner and outer ends, and wherein longitudinally sliding said dome along said base until said bottom edge of said end wall is configured adjacent one of said longitudinally opposed ends of said base defines an interior cavity; a plurality of LED warning light assemblies installed in said interior cavity of the warning light; a plurality of mounting assemblies for fixing said LED warning light assemblies in the interior cavity of the warning light; and a plurality of control circuits for selectively energizing the LED warning light assemblies. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
