The invention discloses a distant light guiding and lighting window, which is a light guiding cable distant natural light transmitting and lighting device consisting of a lighting head, a light guiding cable, a light output port and a dimming and light supplementing assembly. The lighting head is arranged on the external surface of a building for collecting natural light; the light guiding cable passes through or is adhered to a framework floor wall body of the building in a plurality of modes and then is connected with the indoor light output port for outputting the illuminating light; an electric light supplementing lamp in the light output port supplements the light or illuminates at night; and the dimming and light supplementing assembly enables operation and control to be intelligent and convenient through an operation switch which is fixedly arranged or subjected to wireless remote control by using a modern electronic technique. The distant light guiding and lighting window leads the natural light in to illuminate a dark zone, has durability, saves considerable illumination energy consumption, and also transmits the indoor illuminating light out of the building to decorate a landscape of the building at night; and the distant light guiding and lighting window is novel configuration and novel hardware for novel indoor ornament and beautification and the development of a novel function, opens up a novel design direction and novel application of low carbon, energy conservation and efficient use in building space layout, can initiate infinite innovation of architectural pattern and space utilization, and is full of infinite charm and prospect.
