Sistemas y métodos de iluminación que prestan control de resplandor activo

APARATO LUMÍNICO REGULADOR ACTIVADO POR RANGOS QUE PROPORCIONA CONTROL DE RESPLANDOR ACTIVO, QUE COMPRENDE UNA PRIMERA FUENTE DE LUZ REGULABLE, UN TELÉMETRO ACOPLADO OPERATIVAMENTE CON LA PRIMERA FUENTE, PARA DETERMINAR UNA DISTANCIA ENTRE LA FUENTE Y EL TOPE DE UN OBJETO, UN CONTROLADOR PARA DETERMINAR UNA ALTURA ENTRE EL TOPE Y UNA SUPERFICIE DE APOYO Y CONFIGURADO PARA REGULAR LA PRIMERA FUENTE CUANDO LA ALTURA EXCEDA UN PRIMER UMBRAL DE DISTANCIA; SISTEMA Y MÉTODO DE ILUMINACIÓN. A light fixture includes a dimmable light source that emits light downwardly, and a downward-looking rangefinder proximate and operatively coupled with the light source. When the rangefinder detects an object at a measured height that exceeds a first threshold, the light source dims according to the measured height. A light fixture that provides illumination for a lighted area includes one or more first light sources that emit high-angle light, and one or more dimmable second light sources that emit low-angle light, into the lighted area. The system also includes a camera that captures images of the lighted area, and an controller that is (a) operable to identify one or more activity locations within the lighted area from the images, and (b) operatively coupled to dim one or more of the light sources that illuminate the one or more activity locations.
