Abstract: In a lighting device provided with a light source module including a plurality of light sources, insufficiency of luminous intensity, illuminance unevenness, and the like due to a low-light light source are compensated for. The lighting device includes the light source module which is composed of the plurality of light sources in a matrix and mounted on a board. A drive circuit individually supplies power to the light sources. A processor controls a lighting status of each of the light sources via the drive circuit. The processor determines a low-light light source that is lower in luminous intensity than at least one light source among the plurality of light sources, and causes at least one light source adjacent to the low-light light source to emit light with a higher luminous intensity than the at least one other light source.

Abstract: An illumination system includes: a light-emitting module including a blue LED light source that emits blue light having a light emission peak in a blue range of from 400 nm to 470 nm and a red LED light source that emits red light having a light emission peak in a red range of from 610 nm to 680 nm; a light regulator that controls a first light intensity, which is light intensity at the light emission peak in the blue range, and a second light intensity, which is light intensity at the light emission peak in the red range, in a light emission spectrum of light emitted by the light-emitting module; and a clock that measures a time. The light regulator causes the second light intensity to change in conjunction with a change in the first light intensity, in accordance with the time measured by the clock.
