摘要： A luminaire can comprise a system that automatically adjusts light output from the luminaire to control light level in an illuminated area. The system can increase light output if the light level in the area falls below a target light level or decrease light output if the light level in the area rises above the target. For example, when the area is illuminated by a combination of sunlight and luminaire light, the light level can be maintained at the target level by gradually decreasing light output as the sunlight contribution increases in the morning and by gradually increasing light output as the sunlight contribution decreases in the evening. The system adjustments can take into consideration whether the light level is offset from the target due to a change in the target or a short-term fluctuation that may be due to a cloud temporarily blocking the sun.

摘要翻译： 照明器可以包括自动调节来自照明器的光输出以控制照明区域中的光级的系统。 如果该区域的光线水平降低到目标光照水平以下，则系统可以增加光输出，或者如果该区域中的光线水平升高到目标值以上，则可以减少光输出。 例如，当通过太阳光和照明灯的组合来照亮该区域时，通过逐渐降低光输出，当阳光的贡献在早晨增加时，并且通过逐渐增加光输出作为阳光的贡献，能够将光水平维持在目标水平 晚上减少 系统调整可以考虑到由于目标的变化而导致的光水平是否偏离目标，或者由于云暂时阻挡太阳而引起的短期波动。
