The invention relates to a control device (1) for controlling the color of light (L) emitted from a light source (2). The control device comprises color variation means (24) for varying the color of said light emitted from said light source and one or more light-emitting elements (26) arranged to indicate an available color variation range for the color of said light emitted from said light source upon operation of said color variation means. The control device 1 further comprises control means (23) capable of controlling at least one color of the light emitted by said light-emitting elements in dependence on said available color variation range for said light emitted by said light source.
摘要:
A luminaire comprising a transparent light guiding structure (2), including a stack of transparent, flat panel light guides (3). Each panel light guide has an in-coupling edge (4) adapted to receive light from said light source and couple this light into the light guide, and at least one out-coupling surface (10, 10a) adapted to couple light out of the light guide, wherein the out-coupling surfaces being distributed along a plane of extension of said light guiding structure. The stacked light guiding structure according to the present invention is easy to manufacture even for large sizes, and consists principally of existing elements (flat panel light guides). Also, an improved transparency can be achieved with this design.
摘要:
A method for controlling an angular distribution of a light-beam emitted by a light-output device (102, 200) comprising a first set of light-sources (105, 211) comprising at least one light-source configured to emit light within a first angular range (221, 231, 241) and second set of light-sources (107, 210) comprising at least one light-source configured to emit light within a second angular range (222, 232, 242), wherein the first angular range is different from the second angular range. The method comprises the steps of: receiving (401) a dimmer setting (VDS) from a dimmer (101); controlling (404), if the dimmer setting is within a first predetermined range, the first set of light-sources to emit light within the first angular range; and controlling (405), if the dimmer setting is within a second predetermined range, the second set of light-sources to emit light within the second angular range. Through the method according to the invention the angular distribution of light emitted from a single light-output device may be controlled using a single switch, thereby avoiding the need for having a plurality of switches and/or new wiring which would otherwise be required.

Disclosed is a retractable lighting fixture having a retractable LED lighting layer. One or more optical layers (40, 240A/B, 340A/B, 440) may optionally be provided over the LED lighting layer (30, 230, 330, 430). The optical layer(s) and the LED lighting layer may optionally be movable relative to one another between at least being in an expanded spaced relation to one another and a compressed relation to one another. One or more LEDs (34, 134, 234A/B, 334A/B, 434) on the LED lighting layer may be individually controllable and such LEDs (34, 134, 234A/B, 334A/B, 434) may be selectively extinguished when they are in a retracted position.

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.
摘要:
An apparatus for waking up a user, the apparatus (1) comprising a light source (3) that is adapted to produce a light effect (L), such as a light beam, that is directed to a user, or at least to a user's head, wherein the apparatus (1) comprises means for displacing the light effect (L) in an upward (Ru) or downward (Rd) direction during a period of time, in order to change a position of the light effect with respect to the user, or at least to the user's head, wherein the means to displace the light effect (L) is adapted to displace the light effect (L) gradually along an amount of displacement during the time period, for instance during a wake-up period until reaching a final wake-up time.
摘要:
The invention provides an illumination device (1) comprising a lighting unit (2). The lighting unit (2) comprises a light source (100) and a substantially flat collimator (200), arranged to collimate light source light (111). The collimator (200) has an entrance window (210), an edge window (220), a top collimator surface (201), a bottom collimator surface (202), a first collimating side edge (230) and a second collimating side edge (240). The lighting unit has an optical axis (O). One or more of the top collimator surface (201), the bottom collimator surface (202), the first collimating side edge (230) and the second collimating side edge (240) comprise n*½ grooves (300), wherein n is a positive integer number, and wherein the grooves (300) independently have a longitudinal axis (301) having a groove direction angle (ω) with the optical axis (O) ≧0° and & and

A puzzle includes light emitting diodes integrated in the puzzle in order to achieve a high level of interaction between the user and the puzzle. The puzzle can adapt to the players needs by increasing or decreasing the difficulty level or by giving the user hints. The puzzle functions not only as a puzzle but may also function as an ambient light (or object) of programmable color point (and layout) when not in use as a puzzle.
摘要:
