Abstract: A lighting device includes an illumination part, and a power connection part adapted to transfer outside power to the illumination part and for preventing an electrical short circuit. The power connection part includes at least two power connectors which are separated from each other and into which the external power is transferred and an insulator provided between the at least two power connectors and coupled with the at least two power connectors.

Abstract: Disclosed are a wall structure and a lighting system using the same. The wall structure in accordance with one embodiment of the present invention includes an installation surface on which an electronic apparatus is installed; a first conductive attachment part provided at the installation surface to be attached to the electronic apparatus, and electrically connected with a first terminal of a power source configured to supply power to the electronic apparatus; and a second conductive attachment part provided at the installation surface to be attached to the electronic apparatus, spaced from the first conductive attachment part, and electrically connected with a second terminal of the power source configured to supply power to the electronic apparatus.

Abstract: A lighting apparatus includes a rail unit, and an electric unit that is installed on the rail unit so as to be adjustable in position. The electric unit makes contact with the rail unit and receives power from the rail unit. In the lighting apparatus according to the present invention, a plurality of electric units can be installed on a rail unit so as to be adjustable in position, and even if the position of each electric unit is changed, power can be reliably supplied from the rail unit to the electric unit. Therefore, the present invention can be effectively used as lighting for several places, for instance, a place with a comparatively large area, or a place where intensely bright lighting is required.
