A lighting device includes a first light source having a first S/P ratio, a second light source having a second S/P ratio that is higher than the first S/P ratio, and a controller configured to performing dimming control of light output from the first and second light sources. The controller performs the dimming control separately on the first and second light sources at least under a snow covered condition.

Lighting device

A lighting device includes first and second light emission units. The first light emission unit emits light having a relatively low color temperature and a high feeling of contrast index. The second light emission unit emits light having a relatively high S/P ratio, which is the ratio of scotopic luminance to photopic luminance. The first light emission unit illuminates a region located at a vertical upper side of a region illuminated by the second light emission unit.
