Abstract: Systems and methods for managing interaction with controllable lighting networks are disclosed. Particularly, a user's input regarding the user's preferred level of interaction with a controllable lighting network is used in conjunction with memories and processors, to selectively allow the controllable lighting network access to the user's personal data such as the user's identity or the user's personal lighting preferences. A user's preferred level of interaction with a controllable lighting network is also used, in conjunction with personal mobile electronic communication devices, to allow the user to control lighting within controllable lighting networks.

Abstract: According to an aspect, a light guiding assembly (1) with a tubular member (2) for guiding light is provided. The light guiding assembly comprises a first layer (51, 61) having a first optical characteristic, the first layer being arranged on an inner wall (5) of the tubular member, and a second layer (52, 62) having a second optical characteristic, the second layer being adjustable at least with respect to the second optical characteristic and with respect to the extent of light allowed to be transmitted through the second layer. The second layer is coupled to a side of the first layer facing away from the inner wall. One of the first and second optical characteristics effects changing of the color of light guided in the tubular member, and the other one of the first and second optical characteristics effects reflection of light guided in the tubular member. Accordingly, the color of daylight guided through the tubular member can be tuned.

Abstract: According to an aspect, a lighting device (10) for a light guiding assembly (1) is provided. The lighting device is adapted to be arranged at an output end (4) of a tubular member (2) of the light guiding assembly. The lighting device comprises a light source (13), and a layer (11) adjustable at least with respect to reflection of light impinging thereon and with respect to the extent of light allowed to be transmitted through the layer. The layer is arranged to reflect light outputted from the output end of the tubular member when the layer has been adjusted so as to be at least partially reflective, and transmit light emitted by the light source through the layer when the layer has been adjusted so as to be at least partially light transmitting. The light redirected by the layer may be part of the illumination output by the light guiding assembly.
