LED lighting system

摘要

A lighting system includes at least one lighting apparatus having a light emitting element capable of emitting a controllably variable light output in a region. A position determination subsystem is capable of determining a position in three dimensions of at least one mobile entity within the region. A control subsystem is capable of variably controlling a light output of the at least one lighting apparatus according to the position of the mobile entity. The system may determine position by radio ranging with mobile electronic elements. The system may include multiple lighting elements and may determine light levels according to positions of multiple mobile entities. The system may include a database of information about lighting elements, mobile entities, and lighting plans that may be selected from mobile electronic elements.
