Patent ID: 7712926

Claim:
A luminaire for providing general illumination, comprising: a housing defining a spatial profile for the luminaire, said housing comprising an output portion; and one or more light modules pivotally coupled within said housing, each of said one or more light modules comprising a light-emitting element, and a respective heat sink and output optics therefor; wherein said one or more light modules are configured to pivot within said housing to thereby adjust a directionality of the light emitted therefrom through said output portion while substantially maintaining the spatial profile of the luminaire; said luminaire further having a substantially longitudinal light-module coupling portion pivotally coupled within said housing to pivot about a longitudinal axis that is substantially parallel thereto, said one or more light modules being pivotally coupled to said coupling portion to pivot about a respective transversal axis that is substantially perpendicular to said longitudinal axis; said respective output optics of at least some of said one or more light modules being provided by an output optics attachment comprising an output optical element and an attachment element, said output-optics attachment being configured to engage said heat sink and said light-emitting element via said attachment element to maintain a thermal coupling between said light-emitting element and said heat sink, while positioning said optical element in optical alignment with an output of said light-emitting element; wherein said attachment element is configured to engage a substrate of said light-emitting element and apply an attachment pressure thereon relative to said heat sink thereby enabling said thermal coupling therebetween; wherein said heat sink comprises one or more attachment lips and said attachment element comprising one or more clips configured to extend beyond said substrate while engaging same and couple to respective ones of said one or more attachment lips.
