Abstract: A system for combining exterior light with artificial lighting, comprising a light shielding arrangement (2) for shielding exterior light from a space (5) and at least one light source (6) arranged to emit artificial light that is directed toward the exterior side of the light shielding arrangement (2), which light source (6) is controllable in response to current exterior lighting conditions. The system further comprises a controller (8) connected to said light source (6), which is arranged to control light emission of the light source (6) in response to a current position of the light shielding arrangement, so as to emulate an effect of exterior light escaping through the light shielding arrangement. The artificial light can thus be controlled (manually or automatically) to compensate for lack of sufficient exterior light, and the controller ensures that the artificial light is emitted in such a way as to be perceived as exterior light.

Abstract: Light-based systems for communicating information associated with the formation of social connections are disclosed. One or more lighting controllers controlling individually controllable luminaires are used in conjunction with communication networks in order to identify and form remote light-based social connections. Additionally, visualization controllers are used in conjunction with visualization infrastructures, visualization actuators, localization systems and identification systems to visually identify proximally present potential social connections.

The luminaire (2,3) comprises a plurality of LEDs (31) positioned in a straight array, and an elongated convergent lens (30) which extends parallel to the array of LEDs (30). The array of LEDs (30) is located at a distance (D) from the plane of symmetry (33) of the elongated lens (30).

Abstract: A tray (200) for growing organic material comprising a plurality of LEDs (204) is disclosed. The tray (200) comprises an upper side (202) and a lower side (206). The upper side (202) is arranged to carry a substrate (210) for growing organic material and the lower side (206) is arranged to radiate the light generated by the LEDs (204). The tray (200) comprises a structure which enables the tray (200) to radiate more heat, generated by the LEDs (204), at the upper side(202) than at the lower side(206) of the tray(200). The tray(200) enables to provide an improved nursery assembly (100), wherein the soil with organic material is heated up with the heat generated by the LEDs (204). In this way, the heat is not wasted to heat up the air but is used to heat up the soil such that it can have a higher average temperature than the air above the organic material.

Abstract: A transparent body comprising at least one embedded LED is disclosed. The embedded LED is arranged to provide a beam of light through the transparent body.

The transparent body, provided with an optical device, allows improved illumination of entities displayed in, for example, showcases and counters.

Abstract: The road-marking system for influencing the distance between vehicles (6, 6?, . . . ) traveling over a roadway (10) comprises: a plurality of road-marking units (3; 3?, 3?, . . . ; 4, 4?, . . . ), the road-marking units being provided with light means for emitting or reflecting light in the direction of a driver of the vehicle (6, 6?, . . . ). In operation, a set of the road-marking units (4, 4?, . . . ) is in an active state, while the remainder of the road-marking units (3; 3?, 3?, . . . ) is in an inactive state. The distance between the active road-marking units (4, 4?, . . . ) in the set is indicative of the desired distance between the vehicles (6, 6?, . . . ). Preferably, the light emitted or reflected by the set of active road-marking units (4, 4?, . . . ) is tuned in response to conditions during the day or during the night.

Abstract: The present invention relates to an atmosphere device (1) with a user interface (3) for controlling the setting of a lighting unit (2a) and/or a fragrance unit (2b) of the atmosphere device (1), thus determining the atmosphere conditions in a room. The user interlace (3) is based on a system comprising a detecting device (4) and transponders (6). By bringing the transponders (6) within the range of detection by the detecting device (4), the transponders (6) will send a return signal, which signal controls the settings of the atmosphere device (1). Each transponder (6) is programmed to control a particular color or a specific light intensity and/or a particular odor spectrum and intensity.
