Wall structure and lighting system using the same

A wall structure comprising:

• an installation surface on which an electronic apparatus is installed;
• an adhering member provided at the installation surface and attached to the electronic apparatus;
• a magnetic body provided at the installation surface;
• and
• a first coil provided at the magnetic body and electronically connected with a power source,
• wherein the first coil supplies power of the power source to the electronic apparatus through an electromagnetic inductive coupling.

A lighting system comprising:

• a lighting apparatus;
• a first conductive attachment part provided at an installation surface, on which the lighting apparatus is installed, to be attached to the lighting apparatus, and electrically connected with a first terminal of a power source configured to supply power to the lighting apparatus;
• and
• a second conductive attachment part provided at the installation surface to be attached to the lighting apparatus, spaced from the first conductive attachment part, and electrically connected with a second terminal of the power source.
