Abstract: An edge-lit light panel is disclosed, which includes a generally planar, transparent light guide. Light, such as from one or more solid state light source arrays, is coupled into the light guide through its lateral edge, and propagates generally laterally within the light guide via total internal reflection. A diffuser is attached to the front or rear face of the light guide, such as by lamination. The diffuser may have a refractive index matched to that of the light guide. The light guide may have one or more concave features on its lateral edge to reduce reflection losses at high angles of incidence. The concave features may include a single, one-dimensional groove that includes all the solid state light sources along a particular straight edge of the light panel, or may include a series of concave dimples, with one dimple for each solid state light source.

Abstract translation: 公开了一种边缘照明的光板，其包括大致平面的透明光导。 诸如来自一个或多个固态光源阵列的光通过其侧边缘耦合到光导中，并且通过全内反射在光导内通常横向地传播。 扩散器例如通过层压连接到光导的前表面或后表面。 扩散器可以具有与光导的折射率匹配的折射率。 导光体可以在其侧边缘上具有一个或多个凹形特征，以减小高入射角的反射损失。 凹形特征可以包括单一的一维凹槽，其包括沿着光板的特定直边缘的所有固态光源，或者可以包括一系列凹陷凹坑，每个固态光源具有一个凹坑。

Abstract: Lighting devices, and methods of manufacturing the same, are provided. A lighting device includes a cover through which emitted light passes and a formed flexible light engine. The formed flexible light engine is placed within a housing, or serves as the housing itself. An interface couples to cover to the housing or the formed flexible light engine. The formed flexible light engine includes a flexible substrate and a plurality of solid state light sources located thereon. The plurality of solid state light sources are configured to emit light through the cover. The formed light engine has a defined shape created during the forming process. This enables placement on the housing within the lighting device, or contributes to the overall shape of the lighting device.

Abstract: A formed lighting device having a shape that extends in three dimensions is provided. The formed lighting device includes a formed flexible substrate having a shape, and a stretchable conductive trace located on the formable flexible substrate. A plurality of solid state light sources are attached to the stretchable conductive trace. The shape of the substrate, and thus the lighting device, extends in three dimensions and includes a three-dimensional structure that beam shapes light emitted from one of the solid state light sources. The three-dimensional structure may be a plurality of peaks and a corresponding plurality of valleys. A set of solid state light sources in the plurality of solid state light sources may be located in the plurality of valleys.
