摘要： According to an embodiment, a lighting device includes a first to fourth light sources, a control unit, and an operation unit. The first to fourth light sources have a different combination of a relatively high/low correlated color temperature and a relatively high/low general color rendering index from each other. The control unit controls at least two of a light flux, the correlated color temperature, and the general color rendering index of each of the light sources. The operation unit designates at least one of the correlated color temperature and the general color rendering index of each of the light sources, and executes spectral distribution with the designated correlated color temperature, or general color rendering index.

摘要： According to one embodiment, a luminaire is provided which can enhance the feeling of brightness of a space and can reduce glare. The luminaire includes an equipment mounted on a ceiling surface. The equipment includes a light source and a light control unit. When an amount of light emitted outside from the equipment is an equipment luminous flux, and a direction right under the equipment has a luminous intensity distribution angle of 0°, the light control unit controls to cause a luminous flux falling within a range of a luminous intensity distribution angle of 90° to 120° to be 20% or more of the equipment luminous flux and to cause a luminous flux falling within a range of a luminous intensity distribution angle of 60° to 90° to be 20% or less of the equipment luminous flux.
