Embodiment Construction

[0055] Figure 1a Firstly, a sectional view of an embodiment of a lighting device 1 according to the invention is shown, which comprises an embodiment of a light deflecting device 2 according to the invention. The light deflection device 2 comprises a planar transparent light guide 4 and a transparent cover layer 6 applied on the light guide 4 at least in regions in a planar manner. The light guide 4 can eg be made of glass or transparent plastic. The cover layer 6 can also be made of glass or transparent plastic, for example. The lighting device 1 also has a lighting source 8 comprising at least one light emitting diode 10 . The illumination source 8 is arranged at an edge 14 of the light guide 4 by means of a holder 12 for light coupling through the edge 14 of the light guide 4 . In order to prevent decoupling of the light in the region of the carrier 12 or to ensure recoupling of the decoupled light, mirroring 16 is performed in the region of the carrier 12 . Also shown ...

Abstract

The invention relates, inter alia, to a light deflection device comprising: a planar, transparent optical waveguide (4, 4') and a transparent cover layer (6, 6') applied to at least some regions of the surface of the optical waveguide, wherein a microstructure (20, 20') is formed between the optical waveguide (4, 4') and the cover layer (6, 6') to decouple light coupled into the optical waveguide(4, 4'), and wherein the microstructure (20) has a plurality of structure elements (20a, 20a') in the form of substantially circular-cylindrical elevations (20a, 20a'). The invention also relates to alighting device and to the use of the light deflection device or of the lighting device.

Description

technical field [0001] The invention relates to a light deflecting device, an illuminating device and applications thereof. Background technique [0002] Devices for deflecting light for optimal glare-free interior lighting of a room are known from the prior art. For example, a light deflecting device is known from German patent specification DE 10 2008 055 857 B4, which consists of a transparent plate or foil and has a strip prismatic lens profile on one side and a cylindrical surface on the other Lenticular lens profile. In this case light deflecting means are used to optimize the utilization of daylight falling on the window surface. In this case, the task of such a system is to deflect the incident sunlight in a room illuminated from the side, so that a better illumination of the depth of the room is achieved. [0003] This arrangement does improve daylight utilization though. However, if there is not enough daylight, artificial light sources must be used. [0004] ...
