A light system includes a light source unit including a laser light source, and a photoelectric transducer having the ability to generate photovoltaic power. The photoelectric transducer generates the photovoltaic power when receiving power feed light emerging from the light source unit. The light source unit may 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 is to be incident on the photoelectric transducer.

Light system

A first light source device emits first light having a first wavelength. A second light source device emits second light having a second wavelength longer than the first wavelength. A splitting unit is configured to split the first light into third light having a third wavelength same as the first wavelength and fourth light having a fourth wavelength same as the first wavelength. A wavelength converter is configured to be excited by the third light to emit fifth light having a luminescence peak at a fifth wavelength between the third wavelength and the second wavelength. A combining optical system is configured to combine the second light, the fourth light, and the fifth light together. A control device is configured to control a light output of the second light source device and a split ratio between the third light and the fourth light in the splitting unit.

Light source system

A lighting system includes a light source unit and a light-distributing member. The light source unit includes a laser light source. The light-distributing member has the function of reflecting incident light that has been emitted as a beam of light from the light source unit toward a target space. The light-distributing member transforms the incident light into lighting light having a different light distribution property from the incident light and distributes the lighting light over the target space.
