Abstract: A luminaire is provided, that includes a housing and a plurality of solid state light sources connected thereto. The housing has a top side, two lateral sides, a protrusion in the top side, and two light source mounting surfaces. The top side is diffusely reflecting and has opposing lateral edges and a center. The lateral sides are specularly reflecting and extend generally downward from the opposing lateral edges of the top side. Each has a respective bottom edge. The light source mounting surfaces extend laterally inward from the respective bottom edges. The plurality of solid state light sources is disposed along the pair of light source mounting surfaces proximate the pair of specularly reflecting lateral sides. These emit light, which travels upward to the top side and is also specuarly reflected by the lateral sides toward the top side. The top side diffusely reflects the light out of the luminaire.

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.
