LIGHTING DEVICE FOR A LIGHT GUIDING ASSEMBLY

摘要

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.
