We consider the problem of daylight estimation in a daylight-adaptive lighting system. In such a lighting system, the dimming levels of light sources are adapted to changing daylight such that a desired illuminance distribution is achieved at the workspace plane. Each light source has an associated light sensor at the ceiling that measures the net illuminance, due to contributing light sources and daylight, for a given sensor opening angle. We present a daylight estimation method under the scenario of a few light sensor failures, based on fusion of illuminance measurements at functioning light sensors. The proposed fusion method is used to estimate daylight illuminance values at the zones corresponding to failed light sensors and is a solution of a quadratic programming optimization problem. The efficacy of the solution is shown using photometric numerical data.
