Document Type and Number:
Japanese Patent JP2011512001
Kind Code:
A
Abstract:
The present invention provides a method and apparatus for auto-configuring a lighting unit (10), such that a first light source (20) is associated with a first unique CDMA modification signal. A signal provided by an optical sensor (60) detecting light can be filtered based on the first CDMA modification signal to determine the correlation between the signals. If the correlation between the sensor signal and the first CDMA modification signal is lower than a predefined value, a successful association is made.
