Providing, measuring and demonstrating highly effective uplighting
First Claim
1. A method for providing illuminating light for improved visibility or reflectivity of objects in a space having surrounding areas or space comprising:
- a. providing a lighting system including a plurality of light sources for providing illumination in the space;
b. adjusting or setting spectral distribution from at least some of the light sources according to spectral reflectance characteristics of at least one of the objects and the spectral power distribution and luminance of a surrounding area or space to improve visibility or reflectivity of the object in contrast to the surrounding area or space.

Abstract
A method, system, or apparatus for evaluating and/or improving illumination of a wide area target area or space above the same. Illumination of the area or space is evaluated relative to conventional illumination levels and spectral features. At least a portion of illumination is adjusted in some aspect of spectral profile to improve contrast between a target in the space or aspects of the target area or space. The adjusted illumination can be uplight, downlight, or both. Optionally, an object is launched to a known height above a lighting location, and the luminance from the object is read by a calibrated sensor, enabling verification of adequate uplighting.

7. A method for providing uplight optimized for visibility or reflectivity of an object within the uplighting comprising:
-
a) measuring uplighting illumination with a conventional illumination of a target or a target area; and b) measuring spectral luminance of background of an object and adjusting or setting uplighting for better contrast of the object relative to background to the space than the conventional illumination based on the measurements. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

-
a. a wide area lighting system including plural solid state light sources in each of plural luminaires positioned and aimed to provide illumination and uplight relative to the sport field; b. a launcher or an elevator adapted to either propel an object at a known trajectory or suspend an object to a known height relative to the sports field; b. a sensor adapted to measure a characteristic of the uplight relative the object; and d. a processor adapted for communication with the sensor and having programming to evaluate uplighting performance relative to the illuminated sports field from the sensor measurements. - View Dependent Claims (23, 24)
