Abstract:
Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.
Abstract:
In one aspect, a circuit board includes a base board and a layer of an elastic material comprising a first surface and a second surface. The layer of elastic material is adhered to the base board via the first surface. The circuit board further includes an electrical trace disposed on the second surface of the layer of elastic material. At least a portion of the layer of elastic material stretches or shrinks when the base board expands or contracts. A method of manufacturing a circuit includes obtaining an aluminum board, obtaining a layer of an elastic material, and applying a layer of adhering material to a surface of the aluminum board. The method further includes disposing the layer of the elastic material onto the layer of adhering material, and adhering the layer of the elastic material onto the aluminum board via the layer of adhering material.
