Abstract: A luminaire is provided. A main surface of a light-guiding panel included in the luminaire includes a reflecting area having a plurality of approximately conical recesses. An angle θ formed by a lateral surface of each of the recesses and the main surface of the light-guiding panel satisfies a condition defined by a distance D from a center position of a light source to a center position of the reflecting area, a distance H from an illumination target surface to the center position of the light source, an angle γ which the light-guiding panel forms with a horizontal plane, a refractive index n of the light-guiding panel, and a surface roughness Ra of the lateral surface of each of the recesses.

Abstract: In a plant growing system, a first light source irradiates a plant with light having a peak wavelength in a range from 380 to 560 nm and a peak wavelength in a range from 560 to 680 nm and a second light source irradiates the plant with far-red light having a peak wavelength in a range from 685 to 780 nm. Further, a control unit controls the first and the second light source to perform respective irradiation operations and a time setting unit sets a first and a second time zone in which the control unit controls the first and the second light source to perform the respective irradiation operations. The first time zone ranges from a first predetermined time before sunset to a second predetermined time after sunset, and the second time zone starts after the first light source completes its irradiation operation.

Abstract translation: 在植物生长系统中，第一光源向植物照射峰值波长在380至560nm的范围内的峰值波长和560至680nm范围内的峰值波长，第二光源照射具有远紫外线的植物， 峰值波长在685〜780nm范围内的红光。 此外，控制单元控制第一和第二光源以执行各自的照射操作，并且时间设置单元设置控制单元控制第一和第二光源以执行各自的照射操作的第一和第二时区 。 第一时区的范围从日落前的第一预定时间到日落后的第二预定时间，第二时间区在第一光源完成其照射操作之后开始。
