Title: Lighting fixture

Abstract

A lighting fixture can comprise a substantially flat sheet of metal supporting a circuit that comprises one or more light emitting diodes with one or more associated optics for manipulating emitted light. The circuit can be attached to, mounted next to, or integrated with the sheet of metal. In some examples, a layer of dielectric material adheres to the sheet of metal, and circuit elements adhere to the layer of dielectric material. Such circuit elements may comprise electrical traces, light emitting diodes, and/or a light emitting diode driver. The sheet of metal can provide a substrate for the circuit or a support for a freestanding circuit board that may be rigid or flexible.
