Abstract
A heat sink with bi-directional LED light source is provided. The heat seat includes a plurality of LED light sources mountable to top and bottom surfaces of the heat sink. The heat sink further includes a partial or through bore extending from one end of the heat sink to the other. The through bore contains power or power and data conductors between fluorescent receptacle end caps. The heat sink may include integral heat dissipating fins extending outwardly from at least one of the said heat sink sides. Light emitted from the plurality of light sources is redirected using lens optics to illuminate at least one surface above or below the heat sink.
Claims26
A heat sink assembly comprising:
- a single substantially solid or solid core detachable linear heat sink having at least two exterior flat surfaces;
- a plurality of external heat dissipating fins;
- and
- a plurality of light sources retained on the at least two exterior flat surfaces of the core, wherein:
- the plurality of external heat dissipating fins and the heat sink are a unitary body with the plurality of external heat dissipating fins extending outwardly and from a surface positioned substantially perpendicular to the at least one exterior flat surface of the heat sink;
- heat generated by the plurality of light sources is substantially transferred to the heat sink and then substantially dissipated through the plurality of heat dissipating fins;
- the heat sink and the plurality of heat dissipating fins are surrounded by free-flowing air;
- and
- a length of a maximum dimension of the core and one fin is greater than a length of a dimension of the core taken perpendicular to said at least one exterior flat surface, wherein light is emitted from the at least two exterior flat surfaces in opposite directions from the core.
