A light fixture, e.g., as an artificial skylight, in which light within a region defined by x, y color coordinates (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14) exits a first light engine, and light within a region defined by coordinates (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38) exits a second light engine. Also, light fixtures in which a second light engine comprises a sidewall, and light exiting a first light engine passes through space defined by the sidewall; light fixtures in which first and second light engines are able to output light providing different CS values at a luminance; light fixtures wherein light incident on a surface of the fixture and cumulative light exiting the fixture have different color points; light fixtures wherein light distribution characteristics of light engines differ; and/or other features. The invention also relates to corresponding methods.

A system and method for a flameless candle. The candle comprises a candle base and a lamp shade extending upward from the candle base. The lamp shade is shaped to form an internal cavity. Within the internal cavity is a core which has a plurality of LEDs. The core is electrically coupled to a power source such that, when powered, the LEDs can become illuminated and non-illuminated to resemble a dancing flame.

A lighting fixture appears as a skylight and is referred to as a skylight fixture. The skylight fixture has a sky-resembling assembly and a plurality of sun-resembling assemblies. The sky-resembling assembly has a sky-resembling optical assembly and a sky-specific light source, wherein light from the sky-specific light source exits a planar interior surface of the sky-resembling light optical assembly as skylight light. The plurality of sun-resembling assemblies are arranged adjacent one another and extend downward from a periphery of the sky-resembling assembly. Each of the plurality of sun-resembling assemblies has a sun-resembling optical assembly and a sun-specific light source, wherein light from the sun-specific light source exits a planar interior surface of the sun-resembling optical assembly as sunlight light.

In various embodiments, a transom light arrangement may include a transom, which is arranged between a construction element and a transom light, a light source arrangement, which is mounted at least one of on or in the transom, with the light source arrangement or the transom defining a horizontal plane, and a screen structure. The light source arrangement and the screen structure are arranged relative to one another and are configured such that a spatial region above the horizontal plane is illuminated using the light source arrangement.

The invention relates to a lighting device for at least one plant, comprising an artificial lighting unit for providing artificial light for lighting the plant; a sunlight unit for providing sunlight for lighting the plant; a mixing unit for generating a mixed light consisting of the artificial light and the sunlight; a distributing unit for distributing the mixed light and lighting the plant with the distributed mixed light; and an adjustment unit for adjusting a property of the mixed light. The invention provides a lighting device for at least one plant, i.e., one or more plants, wherein the device can be used in an energy-saving manner for indoor farming.

A method and system for collecting and distributing generated and/or solar radiation. The distribution is a pulsed distribution. A pulsed distribution subsystem combining a generated radiation source with a solar radiation collector is provided. Radiation from the pulsed distribution subsystem is provided to one or more discrete distribution systems; the discrete distributions systems transmit and distribute radiation, such as visible light, to one or more end use points in a facility.

A luminaire includes a housing, a luminous zone coupled with the housing, and one or more transition zones coupled with the housing and disposed adjacent to the luminous zone. The luminous zone provides a first light to an illuminated area, and the one or more transition zones provide a second light to the illuminated area. The first light is harsher than the second light. A method of illuminating an area includes providing a first light to the area from a luminous zone of a luminaire and providing a second light to the area from one or more transition zones disposed adjacent to the luminous zone within the luminaire. The first light is a harsher light than the second light.

A light source generally comprising a light tube configured with artificial light sources and sustainable sources of energy is disclosed. The light source may provide natural light during daylight hours, and a combination of natural light and artificial light, or only artificial light during hours when natural light is diminished or not available. The resultant light output may be constant and the artificial light may be powered by sustainable energy sources such as solar panels and rechargeable batteries.

An embodiment can include a lamp safe system that includes an inner casing member and an outer casing member, a base member, a lampshade, a lamp body, and a base member. A inner casing member can move in and out of an outer casing member, and a lamp body member can be placed over and removably attached to an outer casing member. An inner casing member can include two or more walls, and a top surface and a bottom surface. An inner casing member can have attachment points for a lead, screw, a lead screw nut, and guide rails. An inner casing member can have a locking mechanism that can keep the inner casing member inside an outer casing member and lamp body. An outer casing can substantially surround an inner casing. An outer casing can have attachment points for an inner casing member to move in and out of through guide rail supports An inner casing member can move in and out of an outer casing member through a motor rotating a lead screw. An electronic controlling member can have a microcontroller that can be connected to a smart phone and can allow a user to send and receive information from a lamp safe system.
