Abstract: Techniques are disclosed for maintaining consistent lumen output of a lighting assembly over time. By maintaining a consistent lumen output, it is possible to maintain acceptable color stability where color mixing of multiple outputs is used. The lighting assembly may be any lighting configuration that might suffer from lumen depreciation and/or color drift over time, and may include any type(s) of light source(s) that may be monitored and driven accordingly. The lighting assembly, in addition to light source(s), includes a photo detector and a directed light source, such as a laser. The directed light source provides a golden sample for use in calibrating the photo detector, which in turn monitors lumen output of the light source(s). Drive signals are adjusted to account for lumen depreciation of the monitored light source(s).

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.

Abstract: Systems and methods of Planckian and non-Planckian dimming of solid state light sources are disclosed. For a given first range of correlated color temperature values on the 1931 CIE Chromaticity Diagram, the current through a plurality of solid state light sources is adjusted so that the light output thereby follows the correlated color temperature values relating to the black body curve over that given first range. For a given second range of correlated color temperature values, the current through a plurality of solid state light sources is adjusted so that the light output thereby deviates from black body curve and instead relates to a series of coordinates that tracks a line between the curve and a color point for one of the solid state light sources.
