## 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.

## Claims

### Claim 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 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 light generated by the light source is transmitted, and which includes a plurality of light-transmissive holes, which are formed by perforating the upper plate upward from below,
wherein at least a portion of light, generated by the light source, is emitted upward to the upper plate through the at least one light-transmissive portion, and
wherein one of the plurality of light-transmissive holes is provided with a coupling member connected to the energy supply module.

### Claim 2 (depends on 1)

The table top according to claim 1, wherein:
the light source is disposed in plurality to correspond to the plurality of light-transmissive holes.

### Claim 3 (depends on 2)

The table top according to claim 2, wherein the plurality of light sources are disposed on at least a portion of a periphery of the energy supply module.

### Claim 4 (depends on 2)

The table top according to claim 2, wherein the plurality of light-transmissive holes determine a connection position of the energy supply module.
