Abstract:
To provide a lighting system, with an irradiation direction of light made variable, which can continuously change the irradiation direction with a large change width.
The lighting system 1 is provided with a plurality of light source parts 2 having mutually different directions of optical axes 21 and false light sources 3 in which the optical axes 21 of the light source parts 2 overlap each other. The false light source 3 has an optical member 4 which can freely change continuously advancing directions of light by refraction. Thereby, the irradiation direction of light can be greatly changed by switching over the light source parts 2 to be lighted and the irradiation direction can be continuously interpolated by the optical member 4.
