Abstract: A lighting system comprising one or more lighting devices mounted on a pole and operable to illuminate an outdoor environment; a photosensor, wherein a sensing region associated with the photosensor is directed onto a surface of the pole to detect light reflected off said surface; and a controller comprising an input for receiving a signal output from the photosensor. The controller is configured to: detect an object in the outdoor environment based on detecting a change in the light reflected off the surface in response to receiving said signal; and control the one or more lighting devices in response to detecting the object.

Abstract: The invention relates to a method for determining an unknown position, i.e. height and/or orientation, of a light source within a locality. The determination is based on a first image of a scene within the locality acquired by a camera in such a manner as to contain a light footprint of light emitted by the light source from the unknown position. The method includes steps of processing the first image to determine one or more characteristics of the at least the portion of the light footprint within the first image, comparing the determined characteristics with one or more corresponding known characteristics of a light footprint of light emitted by the light source from a known position to determine a deviation between the determined and the known characteristics, and determining the unknown position of the light source based on the determined deviation.

Abstract: A controller comprising: an output for controlling lighting device(s)to illuminate an environment; an input for receiving a signal output from a sensor of a first type and a sensor of a second type, wherein the sensor of the second type consumes more power, but provides more accurate motion detection than the sensor of the first type; and a control module configured to detect motion of objects in the environment in response to receiving at least one of the signals, and control the lighting device(s) based on detected motion of objects. The control module configured to disable the sensor of the second type, and use the sensor of the first type to detect motion of objects when higher traffic density of objects passing through the environment occurs, and use at least the sensor of the second type to detect motion of objects when lower traffic density of objects occurs.

Abstract: An illumination controller is provided. The illumination controller comprises a light sensor device having a first light sensor arrangement configured to sense light within a first spectral range including non-visible light and excluding a sub-range constituted by at least a major part of the visible light, and a second light sensor arrangement configured to sense light within a second spectral range including at least a part of said sub-range. Furthermore, the illumination controller comprises a control unit connected with the light sensor device and arranged to determine an amount of daylight on the basis of an output signal of the first light sensor arrangement and a predetermined function, which characterizes the relationship between the spectral power distribution of the infrared spectrum of daylight and the spectral power distribution of the visible spectrum of daylight, and to determine an amount of artificial light on the basis of an output signal of the second light sensor arrangement and the output signal of the first light sensor arrangement. The illumination controller is arranged to control illumination on the basis of said amounts of daylight and artificial light.

Abstract: An object detection system is for object detection within a field of view. A light source provides detection illumination to the field of view and a sensor senses reflected light from the field of view. Time of flight analysis is used to provide distance or presence information for objects within the field of view. The controller is adapted to derive a signal quality parameter relating to the distance or presence information and to control the light source intensity in dependence on the signal quality parameter. In this way, energy savings are made possible by adapting the detection system settings to the scene being observed.
