COMPOSITE LIGHT SOURCE SYSTEMS AND METHODS

摘要

A composite light source includes a plurality of illumination panels, that emit light of a fixed color and a variable luminous intensity. Over time, the luminous intensities of at least two of the illumination panels vary, while a combined luminous intensity of the illumination panels remains about constant. Another composite light source includes a plurality of illumination panels that emit light. Each illumination panel of at least a first subset of the plurality of illumination panels emits the light with a first luminous intensity, and each illumination panel of at least a second subset of the plurality of illumination panels emits the light with a second luminous intensity that is different from the first luminous intensity.

1. A composite light source, comprising:
a plurality of illumination panels that emit white light characterized by a luminous intensity; wherein: the light emitted by the plurality of illumination panels combines to form a far field photometric distribution characterized by a luminous intensity at each given angle from the composite light source; and the luminous intensities of the light emitted by the plurality of illumination panels are controlled such that: the luminous intensities of the light emitted by at least some of the plurality of illumination panels change over time, and the luminous intensity changes of the light emitted by the at least some of the plurality of illumination panels are complementary, such that the far field photometric distribution at each given angle is characterized by the luminous intensity at the given angle from the composite light source remaining about constant over time.
