Abstract: An integrated light engine including flexible optics and a flexible light source, and lighting devices including the same, are provided. The integrated light engine includes a flexible light source configured to emit light, and flexible optics coupled to the flexible light source. The flexible optics beam shapes light emitted by the flexible light source. The integrated light engine is capable of entering a set of states, such that a portion of beam shaped light emitted by the integrated light engine in a first state is aimed in a first direction and a portion of beam shaped light emitted by the integrated light engine in a second state is aimed in a second direction. Different combinations of the flexible optics with the flexible light source result in the integrated light engine being able to enter a number of flexed states or being held in a substantially flat, substantially stiff state.

Abstract: Light control films, and lighting devices including the same, are disclosed. The light control films include a single layer of light transmitting material having a first side and a second side. A plurality of first microstructures are formed in the first side. The first microstructures are configured to receive incident light from a light source and produce an off axis (e.g. batwing) light distribution in a field downstream of the second side of the light control film. In some embodiments, a plurality of second microstructures is formed on the second side of the light control films and are configured to reduce the glare produced by light emitted from the light source passing through the film.

Abstract: Cellular lighting elements and lighting devices including the same are disclosed. A cellular lighting element includes a substrate including a solid state light source, and a light control film. The light control film is made of a single layer of light shaping material. The light control film is formed so as to create a cellular shape, which surrounds, at least in part, the solid state light source. The formed light control film and the substrate form a chamber, which defines an area. The solid state light source is located in the area within the chamber. Plurality of such cellular lighting elements may be joined together form lighting devices.

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.
