System, method and apparatus using addressable light sensors
In one embodiment, a light measurement is acquired from each of a plurality of illumination zones. Each light measurement is digitized, and values derived from the digitized light measurements are stored, proximate to where the light measurements are acquired. The values derived from the digitized l...

| description | In one embodiment, a light measurement is acquired from each of a plurality of illumination zones. Each light measurement is digitized, and values derived from the digitized light measurements are stored, proximate to where the light measurements are acquired. The values derived from the digitized light measurements are then transmitted to a central control system, and light emitted by the illumination zones is regulated based on determinations made by the central control system. In some cases, the light measurements may be acquired and transmitted via a light sensor package having: a light sensor providing an analog output proportional to received light; an analog-to-digital converter to convert the analog output of the light sensor to a digital value; a memory to store a value derived from the digital value; and an addressable communication interface to transmit the stored value to an external control system. |
