1. An anti-blinding illumination system, comprising: (a) a sensor for detecting the presence of at least one predetermined object within an illumination beam, (b) a controller for processing data from the sensor, (c) a light source having multiple narrow angle microbeams making up said illumination beam, said source being capable of being controlled so as to selectively reduce the intensity of individual microbeams in its beam, said controller providing feedback to cause the intensity of the selected microbeams to be reduced in response to said predetermined object, whereby said illumination beam having a high level of illumination is in operation at all times, with only selected portions of the illumination beam being reduced by said controller.
