Abstract
A lighthead mounting structure provides both precise alignment of a lighthead and an effective heat transfer path away from heat generating components of the lighthead. Cooperating aluminum brackets are configured to lock together and overlap to provide an effective heat transfer path.
Claims14
A thermal transfer and support assembly comprising:
- a substantially planar thermally conductive support;
- a heat generating electronic component mounted in thermally conductive relationship to a first side of said support;
- a first bracket secured to a second side of said support, said first bracket constructed of thermally conductive material and arranged to conduct heat away from said support, said first bracket comprising a first flange facing said support and a second flange substantially perpendicular to said first flange, said second flange including a locating tab and a first fastener opening;
- a second bracket of thermally conductive material comprising a substantially planar mounting surface, said mounting surface defining a tab receptacle and a second fastener opening;
- and
- a fastener,
- wherein said first bracket is secured in a predetermined fixed orientation with respect to said second bracket by inserting said locating tab into said tab receptacle and inserting said fastener through said first and second fastener openings, said first bracket second flange and said second bracket mounting surface providing a thermal pathway for heat generated by said heat generating electronic component.

A warning light for use with a motorized vehicle, said warning light comprising:
- a lighthead having an intended direction of light emission, said lighthead comprising:
- a thermally conductive LED support having first and second substantially planar surfaces;
- a plurality of LED light sources, each said LED light source having a die, an optical axis originating at said die and a thermal slug, said die emits light when power is applied to said LED, said light emitted on a first side of said slug in a pattern surrounding said optical axis, said LED light sources mounted with a second side of said slug in thermally conductive relationship to said first side of said support;
- a reflector defining at least one opening and a generally concave reflecting surface, said reflector mounted to said first side of said support with said LED light sources positioned in said at least one opening so that light from said plurality of LEDs passes through said reflector;
- and
- a first bracket constructed of thermally conductive material and comprising first and second substantially planar flanges, said first flange being perpendicular to said second flange, said first flange secured to said support second side in thermally conductive relationship thereto and said second flange comprising an alignment tab and a first fastener opening;
- a fastener;
- and
- a second bracket constructed of thermally conductive material and having a substantially planar mounting surface, said mounting surface defining an alignment slot and a second fastener opening, said alignment tab received in said alignment slot and said fastener received through said first and second fastener openings to secure said first bracket to said second bracket in a pre-determined fixed relationship, said first bracket defining a conductive heat transfer path from said support to said second bracket.

A lighthead mounting assembly comprising:
- a lighthead comprising a first sheet metal bracket, said first bracket comprising first and second perpendicular planar flanges adjoining at a bend, said second flange including a pair of protruding alignment tabs and defining a first fastener opening;
- a second sheet metal bracket having a mounting surface defining a pair of alignment slots and a second fastener opening arranged to cooperate with the alignment tabs and first fastener opening of said lighthead;
- and
- a fastener,
- wherein said alignment tabs are received in said alignment slots and said fastener extends through said first and second fastener openings to secure said lighthead to said second bracket in a pre-determined fixed relationship.
