    Abstract: 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.

    Abstract: According to one embodiment, a luminaire includes a dim lighting circuit, an emergency unit, a dimming-signal input section, and a dimming control circuit. The dim lighting circuit dimly lights a light source at a dimming ratio corresponding to a dimming signal. The emergency unit includes a charging circuit for charging a battery with an external power supply in a normal time and supplies a power supply of the battery to the dim lighting circuit in an emergency. The dimming-signal input section receives the input of the dimming signal from the outside. The dimming control circuit gives the dimming signal input from the dimming-signal input section to the dim lighting circuit in a normal time and gives a dimming signal having a dimming ratio for an emergency to the dim lighting circuit in an emergency.
