Abstract
Alighting system includes: a light-discharging portion configured to irradiate a space with light from a duct configured to propagate outside light; a light-diffusing portion disposed so as to cover the light-discharging portion and configured to diffuse light entering an incident surface and going out from a light-emitting surface facing the space; and a light source unit including a light source configured to emit light directed toward the incident surface of the light-diffusing portion. Accordingly, light emission of the light-emitting surface is controlled irrespective of the condition of the outside light and hence desired illumination is realized.
Claims31
A lighting system comprising:
- a light-discharging portion configured to irradiate an interior space with light from a duct configured to propagate outside light;
- a light-diffusing portion disposed so as to cover the light-discharging portion and configured to diffuse light entering an incident surface and exiting from a light-emitting surface facing the interior space;
- and
- a light source unit including a light source configured to emit light directed toward the incident surface of the light-diffusing portion.
A lighting system, comprising:
- a light-discharging portion configured to irradiate an interior space with light from a duct configured to propagate outside light;
- a light-diffusing portion disposed so as to cover the light-discharging portion and configured to diffuse light entering an incident surface and exiting from a light-emitting surface flush with a ceiling of the interior space and facing the interior space;
- a light source unit including a light source configured to emit light toward the incident surface of the light-diffusing portion;
- and
- a light source control unit configured to adjust the light source.
A lighting system, comprising:
- a light-discharging portion configured to irradiate an interior space with light from a duct configured to propagate outside light;
- a light-diffusing portion extending over the light-discharging portion and configured to diffuse light entering an incident surface and exiting from a light-emitting surface facing the interior space;
- and
- a light source unit including a light source configured to emit light toward the incident surface of the light-diffusing portion;
- and
- a light source control unit configured to adjust the light source based on detection of outside light.
