Abstract: An improved LED retrofit kit for troffer style fluorescent lights is presented. The improved retrofit kit includes an interface panel to which is attached one or more LED boards. The interface panel includes flexible legs that allow it to be snapped into a well of a typical troffer housing. The LED retrofit kit further includes an LED power supply or driver with associated wiring which may optionally be attached to the interface panel or the troffer housing. The present invention is improves upon prior art LED retrofit designs by providing a low cost system that may be installed without the use of tools and, in particular, does not require the drilling of any new holes in an existing troffer housing.

Abstract: A heat sink of compact design that allows for direct mounting of solid state lights such as LED arrays to the heat sink, while providing a physical arrangement that maximizes the surface area available for effective heat dissipation, is provided. The heat sink of the present invention features a hollow, polyhedral core body and an outer structure comprised of a plurality of mounting surfaces for solid state lights. The outer structure is generally in the form of a tapered polyhedron with relieved cutouts at the corners to form a plurality of triangular shaped heat transfer structures.

Abstract: An improved streetlamp featuring separate compartments for the lamp, ballast, photocell and wiring is provided. All electrical components of the streetlight are sealed from the elements and infestation from insects such as bees and wasps. All of the compartments may be readily opened without the use of tools and each electrical component and the light-glass can be readily removed and replaced with simple hand tools. Features for improved heat transfer to the atmosphere which results in a cooler running and longer lasting lamp are also provided.
