Abstract

One aspect relates to combining an at least one LED-based secondary general illumination lighting with an at least one primary general illumination lighting to at least partially provide an at least one combined general illumination lighting. The aspect further comprises sensing one or more sensed optical characteristics of an at least one alternate general illumination lighting. The aspect further comprises controlling at least one controlled optical characteristics of the at least one LED-based secondary general illumination lighting to control the at least one combined general illumination lighting at least partially responsive to the sensing the one or more sensed optical characteristics of an at least one alternate general illumination lighting.

First claim

The invention claimed is:

a second sensor configured to detect a second range of optical characteristics from incoming ambient light; and
a controller receiving a first sensor signal from the first sensor and a second sensor signal from the second sensor, the controller including a control algorithm to provide an output signal to the at least one LED-based secondary general illumination lighting component, the output signal being based on the first sensor signal and the second sensor signal, the control algorithm used to generate the output signal to adjust the at least one combined general illumination lighting closer to a first optical characteristic target in the first range of optical characteristics and to a second optical characteristic target in the second range of optical characteristics.
