1. A light system comprising:
a light source unit including a laser light source; and
a photoelectric transducer having the ability to generate photovoltaic power,
the photoelectric transducer being configured to generate the photovoltaic power when receiving power feed light emerging from the light source unit,
the light source unit being able to cause the power feed light and light for lighting for lighting up a target space to emerge from the light source unit itself, the power feed light being to be incident on the photoelectric transducer,
the light system further comprising:
a light-distributing member configured to reflect at least a part of the light for lighting and thereby transform at least the part of the light for lighting into lighting light having a different light distribution characteristic from the light for lighting to have the lighting light distributed over the target space; and
a holding member that holds the photoelectric transducer and the light-distributing member.
