PROBLEM TO BE SOLVED: To provide an illumination device, a control method and a program in which, based on an external element suitable for an installation environment or a plurality of external elements of installation places, control can be performed so that a proper lighting pattern or surprising lighting pattern can be obtained.SOLUTION: An illumination device 1 is formed so as to control LEDs 30 (light sources) on the basis of patterns generated by generating a first pattern in which the LEDs 30 are lighted by making the intensity of the quantity of a plurality of kinds of LEDs 30 different in the size, shape or light color have fluctuation characteristic at 1/f, a pattern in which the first pattern is changed in accordance with the strength of the air volume detected by an air volume sensor 20 or a random pattern (a second pattern) in which the first pattern is further changed randomly. |
