3D puzzle wherein light emitting diodes (LED's) are 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.

A lighting arrangement (100) provides light (117) of a desired color. The arrangement comprises a plurality of light sources (101, 102, 103) that each emit light of a respective color that, when mixed, is perceivable as the desired color. A light detector (197) is configured to receive light (116) reflected by a color reference surface (109) having a specific reference color. The detector also provides a s (105) analyzes the signal from the light detector and recognizes the color of the received light as the color of the reference surface. The controller controls the light sources such that the desired color corresponds to the color of the color reference surface.

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 light guide (200), arranged to collimate light source light (111). The light guide (200) has an entrance window (210), an edge window (220), a first light guide surface (201), a second light guide surface (202), a first side edge (230) and a second side edge (240). One or more of the first light guide surface (201) and the second light guide surface (202) comprise a plurality of grooves (300). In this way, latitudinal collimation is obtained.

The illumination system has an array of light sources (1, 1′, . . . ) such as an array of light emitting diodes arranged in a pre-determined manner in a first plane (11), wherein dsource is a characteristic dimension of the spatial arrangement of the light sources in the first plane. An array of associated lenses (2, 2′, . . . ) is arranged in substantially the same pre-determined manner in a second plane (12). Each lens has substantially the same focal distance flens. The array of lenses is provided at a plane distance dplane from the array of light sources. The plane distance dplane is substantially equal to the focal distance flens of the lenses. The illumination system has displacement means for displacing the array of lenses with respect to the array of light sources so as to obtain a plurality of directional light beams projecting spots on a projection plane arranged at a projection distance dprojection from the illumination system, wherein dprojection≧10×dsource and dprojection≧10×dplane.

The present invention relates to a lighting system (1) with a user interface (3) for controlling the lighting color and/or intensity of a lighting unit (2) determining the lighting conditions in a room. The user interface (3) is based on a system comprising a detection device (4) and transponders (6). Bringing the transponders (6) within the detection device (4) so that they will be detected causes the transponders (6) to send a response signal, which signal controls the lighting color and/or intensity of the lighting unit (2). Each transponder (6) is programmed to control a particular color or a specific light intensity.
摘要:
Simple gestures such as stroking or tapping of a surface (10) can be used to control common functions of electronic systems (16) by positioning one or more sensors (12) on the surface and detecting sounds generated by the interaction with the surface. Signals corresponding to detected sounds are filtered and interpreted either in the system to be controlled or else in the sensors themselves. The direction of movement of a hand (18) stroking the surface can be interpreted as a command to increase or decrease a parameter, such as the sound volume level of a television, for example. Determination of the position of the user's hand is unnecessary. The apparatus is therefore simple, inexpensive, robust and discrete, requiring only a minimum of installation and without being necessarily dedicated to a particular electronic system to be controlled.

This invention relates to a lighting module (101) comprising a carrier (103), a plurality of LED groups (109), arranged in an array on the carrier (103), a mesh (105), arranged at the carrier (103), and a front diffuser plate (107) arranged in front of the mesh (105). The mesh (105) has walls, which are arranged in a geometrical pattern forming a plurality of cells (113), such that the light emitted from at least some of the LED groups, which are adjacent to each other, is mixed before passing the diffuser plate.
摘要:
A waveguide (40; 51; 61), arranged to guide light from at least one light source (53a-c), the waveguide comprising at least one guiding edge (43; 50a-c; 60) adapted to contain the light in the waveguide (40; 51; 61), and an extraction edge (44; 50d) adapted to enable extraction of the light from the waveguide (40; 51; 61), wherein the guiding edge (43; 50a-c; 60) is configured to reflect the light on its way towards the extraction edge (44; 50d). The guiding edge (43; 50a-c; 60) is further configured such that a direction (xr1, Xr2) of reflection of a ray of light impinging on the guiding edge (43; 50a-c; 60), in a given direction (xi) of incidence relative to a general direction (X0) of extension of the guiding edge (43; 50a-c; 60), is dependent on a position (P1, P2) of incidence along the guiding edge (43; 50a-c; 60). The waveguide may be configured such that virtually no light is lost through back-scattering or unintentional extraction or outcoupling through the at least one guiding edge.
