Room divider with illuminated light guide blind blade

A method and a system for controlling at least one lighting arrangement (), in which the lighting arrangement modulates the light () it emits by lighting arrangement data, which contains an identification code identifying the lighting arrangement, a user control device () is suitable to receive the light from the lighting arrangement and to derive therefrom the lighting arrangement data, the user control device measures a property of the received light, apart from it representing data, to provide additional data which is associated with the lighting arrangement which is associated with the identification code contained in the received data, the user control device transmits the lighting arrangement data and the additional data, and a main control device () is suitable to receive the data transmitted by the user control device and to therewith control the operation of the lighting arrangement.

Method and system for lighting control

A portable illumination device, for illuminating an object through a medium having an absorption coefficient, has a lighting unit including at least two differently colored light sources for emitting light having a color distribution and a control unit for adjusting the color distribution. The control unit is adapted to receive a distance estimate corresponding to the distance between the illumination device and the object, and adjust the color distribution depending on the distance estimate, such that light reflected from the object is perceived to have substantially correct color reproduction.
