A lighting system includes an EL unit having a light emitter, a holding frame that holds the EL unit, and a control unit that controls lighting of the EL unit, wherein the holding frame includes a rail-shaped conductive member, and power and communication signals are transmitted between the control unit and the EL unit through the conductive member. With this configuration, since the connection between the control unit and the EL unit is made by the conductive member provided on the holding frame, which holds the EL unit, space for wiring in a residential space can be reduced. Further, simply by placing the holding frame on a mounting surface and attaching the EL unit and the control unit to the holding frame, they are connected. Therefore, without special skills, a resident can install the lighting system as appropriate and can easily replace the EL unit.
