Described herein are ambient lighting devices, methods, and systems that utilize at least one multimode artificial ambient light source, a control unit, and a remote image sensor. The control unit couples to at least one artificial ambient light source and is configured to output at least one control signal to the at least one artificial ambient light source. The at least one multimode artificial ambient light source is configured to output light of varying color and color temperature in response to said at least one control signal. The remote image sensor couples to the at least one control unit and is configured to detect at least one color and intensity characteristic and output an output signal to the at least one control unit, based on said color and intensity characteristic detected.

A modulated passive optical lighting device includes a passive element, such as a window, a sun-room roof, or a skylight. The device also has an optical modulator associated with or incorporated in the device, to modulate light supplied to an interior space to carry data.

Provided is a sunlight lighting system used in a greenhouse or a plant factory. The sunlight lighting system converts sunlight into light with a stable illumination direction and a controllable illumination intensity by means of a combination of a controller, a light condenser, a main driving mechanism and an illuminator, so that the sunlight lighting system meets lighting requirements of high-density stereoscopic cultivation frames. A supporting greenhouse is further comprised, where a facade or a top is provided with a light through hole. A main optical axis of the sunlight lighting system passes through the light through hole. A supporting lighting method is further comprised, which can obtain a better lighting effect with fewer steps.

A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.

The present invention refers to a system including light processing elements, arranged in a respective installation area and combined with a respective construction, at least partially above and/or next to an occupational or passage space, whereby said light processing elements or respective constructions produce a general light distribution over said occupational or passage space, that is more favorable in terms of visual performance and comfort, and that may assist and adjust to activities requiring different levels thereof. The inventive system is used for energy and/or information conversion and distribution, as part of one construction or clusters of constructions, for example disposed along traffic ways.

A system may include a light valve exposed to incident light from an external light source. The light valve may independently modulate multiple wavelength bands of the incident light that are transmitted through the light valve and into an environment that the system illuminates. A control system can operate the light valve to control a spectral distribution of light transmitted through the light valve.

A lighting fixture appears as a skylight and is referred to as a skylight fixture. First and second light engines of the fixture provide different color points, peak light intensity angles, far-field light distribution characteristics, and/or circadian stimulus values. A skylight fixture may include a sky-resembling assembly and a plurality of sun-resembling assemblies, with dedicated optical assemblies and/or light sources. A lighting fixture may include multiple waveguides that different extraction feature patterns and/or may be sequentially arranged.

A light fixture includes a housing with a skylight aperture, and one or more louver blades spanning the skylight aperture. When open, the one or more movable louver blades block little of the light passing through the skylight aperture; in intermediate positions, the louver blades block a portion of the light; when closed, the louver blades block most light from passing through the skylight aperture. The light fixture also includes: a dimmable artificial light source configured to project artificial light toward the illuminated space; a light sensor that detects light illuminating the space; and a control unit that is integrated with the housing and communicates with the light sensor. The light sensor detects intensity and chromaticity information of the light illuminating the space. The control unit controls position of the louver blades and brightness and chromaticity of the dimmable artificial light source, in response to the light sensor.

A light energy conveyance and control system uses a multiple of separately arranged light energy conveyance lenses to define a conveyance path for passing light energy from front to rear, and each light energy conveyance lens has a scatter region for scattering light energy to provide illumination, and the light energy scattered by the scatter region of each light energy conveyance lens is controlled to distribute the light energy on the conveyance path, and the scattered light energy is determined by a scatter area and/or a scatter level.

The present invention is to direct sunlight through the Solar Polymer Light Bar using an exposed solid polymer bar or equivalent through a roof pipe flange down into a flush mounted ceiling light canister and a wide variety of mounting fixtures, including one or more interconnected light canisters, whereby the Solar Polymer Light Bar may be bent as required to avoid roof structural elements and ceiling structural elements when being installed. Optional light gathering and light emitting enhancement means can be added at the upper portion and lower portion of the solid polymer light bar, respectively. Solar powered, battery powered or house AC or DC transformer powered LEDs, CFLs or conventional incandescent light bulbs may be added to increase the light intensity emitted through the night time and dark hours if desired.
