The white light emitting means 104 is arranged in a first relative position with respect to the Fresnel lens 102 to collimate at least a part of the light emitted by the white light emitting means 104 to obtain a collimated directed light beam in a specific direction. The blue light emitting means 106 is arranged in a second relative position with respect to the Fresnel lens 102 to obtain a blue light emission at least outside the collimated directed light beam.

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.
