Abstract
Official abstract text for this publication.
According to one aspect of the disclosure, a lighting system comprises a remote control unit ( 4 ) and at least one lighting device ( 2 a, 2 b, 2 c ) comprising a light driver ( 13 ) and a light emitter ( 14 ). The remote control unit ( 4 ) comprises an image capturing unit ( 5 ) and is arranged to control the lighting device ( 2 a, 2 b, 2 c ). To do so, the remote control unit ( 4 ) receives information relating to current/present settings of the image capturing unit ( 5 ), then determines one or more properties of signals for visible light communications based on these settings. The one or more properties are then communicated to the at least one lighting device ( 2 a, 2 b, 2 c ). Upon reception thereof the light driver ( 13 ) generates a light emitting control signal based on the received properties and visible light communications based on the light emitting control signal is emitted by the light emitter ( 14 ). According to another aspect, a lighting device ( 2 a, 2 b, 2 c ) adapts emitted modulated light and adapts the modulation so as not to correspond to blind-spots of an image capture unit ( 5 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A remote control unit for controlling a set of lighting devices, comprising: a processing unit arranged to determine one or more properties of signals for visible light communications, based on current settings of an image capturing unit, wherein said current settings relate to a current exposure time indication of said image capturing unit; and a transmitter arranged to transmit a control signal pertaining to said properties to said set of lighting…
