OBJECT-DETECTING LIGHTING SYSTEM AND METHOD
First Claim
1. A method for detecting an object using visible light, comprising the steps of:
- providing a visible-light source emitting visible light having a first function of being visible to a person;
connecting a source controller to the visible-light source;
driving the visible-light source into emitting visible light in a predetermined mode;
receiving a reflection/backscatter of the emitted visible light on an object; and
identifying a position of the object as a function of the reflection/backscatter received and of the predetermined mode.

Abstract
An object-detecting lighting system comprises a light source emitting visible light. A source controller is connected to the light source to drive the light source into emitting the visible light in a predetermined mode. An optical detector is positioned with respect to the light source and is adapted to detect the visible light as reflected/backscattered by an object. A data/signal processor is connected to the source controller and the optical detector to receive detection data from the optical detector. The data/signal processor produces a data output associated to the object as a function of the predetermined mode and the detection data.

9. An object-detecting lighting system comprising:
-
a light source emitting visible light and having a first function of emitting visible light for at least one of illuminating an environment and emitting a signal to a person in the environment;
a source controller connected to the light source to drive the light source into emitting the visible light in a predetermined mode;
an optical detector positioned with respect to the light source and adapted to detect the visible light as reflected/backscattered by an object; and
a data/signal processor connected to the source controller and the optical detector to receive detection data from the optical detector, the data/signal processor producing a data output associated to the object as a function of the predetermined mode and the detection data. - View Dependent Claims (10, 11, 12, 13, 14, 15)
