FIELD OF TECHNOLOGY
This disclosure concerns furniture. In particular, this disclosure concerns illuminating furniture and structures therefor.
BACKGROUND
Selection of aesthetically pleasing and practical furniture as well as functional lighting design are key elements in interior architecture.
In conventional solutions, furniture is selected to provide sufficient facilities for any intended activities, and lighting is separately provided to ensure suitable illumination for said activities.
However, especially in case of strict space constraints, providing sufficient levels of high-quality illumination may be challenging. Using conventional solutions, arranging light sources in a manner that results in minimal obstruction for passage as well as simple electrical wiring arrangements may also prove demanding.
In light of this, it may be desirable to develop new solutions related to illuminating furniture. Such solutions may preferably be based on structures that are durable and easy to manufacture and repair.

In the embodiment of FIG. 10, at least part of the tabletop 1001 may be transparent or translucent. In other embodiments, wherein a piece of furniture, e.g., a table, comprises a tabletop, at least part of said tabletop may or may not be transparent or translucent.
The tabletop 1001 of the embodiment of FIG. 10 may have a rectangular, e.g., square, shape. In other embodiments, a tabletop may have any suitable regular or irregular shape, for example, a polygonal, e.g., triangular or quadrilateral, shape or a curvilinear, e.g., circular, elliptical, or oval, shape.
In the embodiment of FIG. 10, the table 1000 comprises a light source 1020, coupled to the furniture frame 1010. Addition of a light source into a piece of furniture, e.g., a table, may facilitate provision of sufficient levels of high-quality illumination, especially in case of strict space constraints. In other embodiments, a piece of furniture, e.g., a table, may or may not comprise a light source, coupled to a furniture frame.
The light source 1020 of the embodiment of FIG. 10 may be a light-emitting diode (LED) source, for example, a LED strip light or a LED light bar. In other embodiments, any suitable type of light source(s), such as LEDs source(s), for example, LED strip light(s) and/or LED light bar(s), may be used.
In the embodiment of FIG. 10, the table 1000 comprises a light guide plate 1030. The light guide plate 1030 has an edge face 1031. The light guide plate 1030 is supported by the furniture frame 1010 and arranged such that light emitted by the light source 1020 is directed into the light guide plate 1030 through the edge face 1031. Such arrangement of a light guide plate and a light source may enable redirecting light emitted by said light source upwards and/or downwards from said light guide plate. Additionally or alternatively, lighting with lower luminance and/or luminous emittance variations may be provided. In other embodiments, wherein a piece of furniture, e.g., a table, comprises a light source coupled to a furniture frame, said piece of furniture may or may not comprise a light guide plate with an edge face, said light guide plate being supported by said furniture frame and arranged such that light emitted by said light source is directed into said light guide plate through said edge face.
In the embodiment of FIG. 10, the light source 1020 of the embodiment of FIG. 10 is arranged into a light guide support groove 1032. Such arrangement of a light source may facilitate directing light emitted by said light source into a light guide plate. In other embodiments, a light source may or may not be arranged into a light guide support groove.
In the embodiment of FIG. 10, the first connector 1011 comprises a leg mounting insert 1012. The leg mounting insert 1012 is arranged into a hollow furniture leg 1050. The table 1000 comprises an electrical cable 1040, extending within leg mounting insert 1012, for supplying power to the light source 1020. Generally, arranging electrical wiring into a leg mounting insert of a connector may reduce obstruction for passage as well as simplify electrical wiring arrangements. In other embodiments, a piece of furniture, e.g., a table, may or may not comprise electrical wiring, e.g., an electrical cable, extending within a leg mounting insert, for supplying power to a light source.
