PROBLEM TO BE SOLVED: To provide an illuminator which performs a desired illumination coping with an environmental change. SOLUTION: An illuminating unit 11 is composed of plural light sources 12 each emitting any one of plural luminous colors. The illuminating unit 11 is disposed in the respective illuminating lamps 1A to 1N. Based on a change in environmental parameters detected by an environmental sensor 21 of a control unit 2, a decision unit 22 selects a desired illuminating light, which is directed to a driving unit 13 of the respective illuminating lamps 1A to 1N through an output unit 23 and a signal line 24. The respective driving units 13 control the driving of the respective light sources 12 based on the directions, so that an illumination coping with the environmental change is performed. |
