Abstract

Devices for providing light and methods and devices for fabricating them are described. Lighting devices having lighting elements (e.g., based on LEDs, OLEDs, or other lighting technology) coupled to a frame allow for efficient dissipation of heat generated by the lighting elements. Each lighting device can be configured to be easily expandable, replaceable, and adaptable to different lighting device systems. A modular lighting device is also described. According to various embodiments, modular stacked frames and/or modular lighting element subassemblies are used. A manufacturing assembly is also described for fabricating the lighting devices. The use of reclaimed materials in the present invention is also described, which may further add value to the apparatus and methods of the present invention.
