Abstract

Provided is a table top including: an upper plate, which is constituted by a plate-shaped non-magnetic member so as to support an electronic or cooking device placed thereon; an energy supply module, which is disposed under the upper plate so as to supply energy to the electronic or cooking device; at least one light source configured to generate light; and at least one light-transmissive portion, which is provided in the upper plate and through which the light generated by the light source is transmitted; and at least one light guide configured to guide the light, generated by the light source, to the light-transmissive portion, wherein the at least one light guide allows at least a portion of the light, generated by the light source, to be emitted upward from the upper plate through the light-transmissive portion.

First claim

What is claimed is:

1. A table top comprising:
an upper plate, which is a plate-shaped non-magnetic member and supports an electronic or cooking device placed thereon;
an energy supply module, which is disposed under the upper plate so as to supply energy to the electronic or cooking device;
at least one light source configured to generate light;
at least one light-transmissive portion, which is provided in the upper plate and through which the light generated by the light source is transmitted; and
at least one light guide configured to guide the light, generated by the light source, to the light-transmissive portion,
wherein the at least one light guide allows a portion of the light, generated by the light source, to be emitted upward from the upper plate through the light-transmissive portion, and
wherein at least a part of the at least one light guide is positioned inside the light-transmissive portion and has a linear shape or a protrusion shape.

2. The table top according to claim 1 , wherein at least a part of the at least one light guide has a shape corresponding to that of the light-transmissive portion.

3. The table top according to claim 1 , wherein the upper plate includes a light source-accommodating portion for accommodating the light source, and the light source is disposed in the light source-accommodating portion.

4. The table top according to claim 3 , wherein the light-transmissive portion includes a plurality of light-transmissive holes, which are formed by perforating the upper plate upward from below, and some of the plurality of light-transmissive holes communicate with the light source-accommodating portion.

5. The table top according to claim 3 , wherein a part of the at least one light guide is positioned in the plurality of light-transmissive grooves, and another part of the at least one light guide is positioned in the light source accommodating portion.

6. The table top according to claim 3 , further comprising a light-blocking plate for restricting outward emission of the light in the light source-accommodating portion.

7. The table top according to claim 3 , wherein the light-transmissive portion includes a plurality of light-transmissive grooves, which are formed by denting the upper plate upward from below, and the plurality of light-transmissive grooves communicate with the light source-accommodating portion.

8. The table top according to claim 7 , wherein a portion of the at least one light guide is disposed in the light source-accommodating portion.

9. The table top according to claim 7 , wherein the at least one light guide includes a light-incident surface, which faces the light source and on which a light emitted from the light source is incident, and a plurality of light-emitting surfaces, from which the light, which has been incident on the light-incident surface, exits.

10. The table top according to claim 9 , further comprising a light-blocking layer, which covers an outer surface of the at least one light guide other than the light-incident surface and a light-emitting surface of the plurality of light-emitting surfaces so as to block outward emission of light from the at least one light guide.

11. The table top according to claim 9 , wherein the light source includes a smaller number of light sources than a number of the plurality of light-emitting surfaces.

12. The table top according to claim 1 , wherein the at least one light guide is disposed along a periphery of the energy supply module.

13. The table top according to claim 1 , further comprising:
a light source-accommodating portion that is formed by denting a lower surface of the upper plate upward; and
a shielding cover for shielding the light source-accommodating portion.

14. The table top according to claim 1 , wherein the light-transmissive portion includes a plurality of light-transmissive holes, which are formed by perforating the upper plate upward from below.

15. The table top according to claim 14 , wherein one of the plurality of light-transmissive holes is provided with a coupling member connected to the energy supply module.

16. The table top according to claim 1 , further comprising a reflective pattern that is formed on the light emitting surface and regularly patterned.

17. The table top according to claim 1 , wherein the at least one light guide is disposed at a portion corresponding to the periphery of the energy supply module.

18. The table top according to claim 1 , wherein the light-transmissive portion includes a plurality of light-transmissive grooves, which are formed by denting the upper plate upward from below.

19. The table top according to claim 18 , wherein one of the plurality of light-transmissive grooves is provided with a coupling member connected to the energy supply module.
