| Zusammenfassung: | The invention provides a lighting device which can make the illuminance of light irradiated to a first irradiation area different from the illuminance of light irradiated to a second irradiation area. The lighting device (200) is provided with a light source part (210) and a penetrating part (270). The light source unit (210) emits light. The light passes through the transmission part (270). The penetration portion (270) has a first penetration portion and a second penetration portion. In the first penetration part, after a part of the light passes through the first penetration part, a part of the light is emitted. In the second penetration part, after a part of the light passes through the second penetration part, a part of the light is emitted. The amount of light passing through the second penetrating portion is a second amount of light, the amount of light passing through the first penetrating portion is a first amount of light, and the second amount of light is smaller than the first amount of light.
