Abstract:
The invention relates to a lighting device and a method of manufacturing such a lighting device. The lighting device (1) comprises a first light emitting element (101) being optically coupled to a light guide (110) having an out-coupling surface (111) for illumination via the light guide. Further, the lighting device comprises a second light emitting element (102) dedicated for direct illumination from the lighting device. The invention is advantageous in that the lighting device provides both a decorative look and a functional illumination, and is still energy-efficient since the light emitted from the second light emitting element is directly emitted from the light emitting element without unnecessary energy-loss.
Abstract:
The invention relates to a light projection system (10) for use in conjunction with a display device (40). The light projection system comprises a light source for emitting light being modulated by video and/or audio content of the display device (40), and a light guide (20). The longitudinal light guide guides light emitted by the light source substantially along a longitudinal axis (26) and projects the light propagating through the longitudinal light guide on a projection surface (50). The longitudinal light guide comprises: a light input window, and a plurality of light out-coupling elements. The plurality of light out-coupling elements project the light on the projection surface via light out-coupling elements comprising sub-sets (70a, 70d) of light out-coupling elements. A particular sub-set (70a, 70d) is arranged for substantially illuminating a particular area (50a, 50d) of the projection surface (50). A luminous intensity emitted by the particular sub-set is dependent on a distance (d a , d d ) along a straight line between the particular sub-set and the particular area, and/or on an angle between the straight line and normal of the projection surface. The effect of the measures according to the invention is that the variation of the luminous intensity over the particular area is reduced.

The invention relates to a mosaic (1), especially for walls, ceilings, or floors, comprising a plurality of individual mosaic elements (2) that are spaced apart by means of joints (3). In order to improve the designing options of said mosaic (1), light-discharging elements (5) can be disposed in the joints (3).

A fiber optic light system for illumination use in a swimming pool or spa environment or the like. The light system includes a light source unit positioned at a suitable dry site for delivering a relatively intense light signal to the input end of one or more optical fibers, wherein this light source unit may include a color wheel for controllably varying the color of said light signal. A support manifold includes a retainer disk for substantially aligning the input ends of the optical fibers with the light signal for optimizing light input thereto. The output ends of the optical fibers are captured within a sealed lens assembly mounted at a submerged or underwater location such as within a pool or spa wall. This lens assembly includes multiple lens segments for distributing the light in a controlled manner within the swimming pool or spa.

A lighting device is disclosed, which comprises a light transmitting element extending along a perimeter such that a hollow is defined by the light transmitting element. The light transmitting element comprises a light in-coupling surface adapted to couple light emitted by at least one light emitting element into the light transmitting element, and a light out-coupling surface adapted to couple light out of the light transmitting element.
