Abstract
The present invention pertains to lighting device systems or methods applicable to off-road utility vehicles. The concepts include light sources for light beam production, a housing enclosure that encompasses internal elements and includes opposing front and rear portions. Inventive concepts further include a heatsink arrangement along an outer surface of the rear portion via a fastening system that is configured to transfer generated heat from the light sources and includes a sealing member with fasteners for securing the heatsink through the housing such that the sealing member becomes positioned between the heatsink and interfacing housing structures.
Claims20
A lighting device of a utility vehicle, said device comprising:
- a light source for producing a light beam;
- a housing enclosure with a transparent cover that encapsulates the light source, the light source packaged within the housing enclosure;
- a sealing member and a heatsink in an assembled condition, wherein the housing enclosure includes a front portion and a rear portion disposed opposing the front portion;
- and
- a number of fins of the heatsink that extend from beyond the front portion and that span through to the rear portion where a rear arrangement of fins extend beyond the housing enclosure, where a front arrangement of fins at the front portion are spaced apart from the rear arrangement of fins at the rear portion by the housing enclosure, the rear arrangement of fins configured to protrude beyond the housing enclosure;
- wherein the heatsink, the sealing member and the housing enclosure are assembled together by a fastening system through securing hardware that forms a structure configured to transfer heat generated by the light source.
A method of assembling a lighting device for a utility vehicle, the method comprising:
- providing a light source for producing a light beam;
- providing a housing enclosure with a transparent cover that packages the light source within the housing enclosure, a sealing member and a heatsink in an assembled condition, wherein the housing enclosure includes a front portion and a rear portion disposed opposite to the front portion;
- and
- producing a number of fins along the heatsink that extend from beyond the front portion and that span through to the rear portion where a rear arrangement of fins extend beyond the housing enclosure, where a front arrangement of fins at the front portion are spaced apart from the rear arrangement of fins at the rear portion by the housing enclosure, the rear arrangement of fins configured to protrude beyond the housing enclosure;
- assembling the heatsink, the sealing member and the housing enclosure together by a fastening system that forms a structure configured to transfer heat generated by the light source.

- and
- where a front arrangement of fins are spaced apart from a rear arrangement of fins by the housing enclosure, the rear arrangement of fins configured to protrude beyond housing enclosure;
- the sealing member emplaced between the heatsink and an inner wall of the housing enclosure along the rear portion;
- and
- where the heatsink that is in thermal contact with the housing enclosure is configured to transfer heat generated by the light source.
