After the first optical fiber coupler couples the sunlight, it uses the optical fiber 13 to transmit the light, and the light is transported to the room for terminal utilization of the light. Due to the adoption of the condenser lens 6 and the fiber coupler, the brightness of the light is high, which can meet the requirements of indoor use.

As the indoor use terminal of the light, the second fiber coupler 15 and the beam splitter 14 are set in this solution, the second fiber coupler 15 corresponds to the first fiber coupler, one of which couples the light, and the other diverges the light After the second optical fiber coupler 15 diverges the light, the light is irradiated on the beam splitter 14, and the beam splitter 14 can divide the light into different beams, and then these split lights can be used in different occasions, increasing the utilization efficiency of the light ; And on the beam splitter 14 is also provided with a shading plate, the shading plate is equivalent to a switch, which can block light in different directions, and is more convenient and humanized to use.

In this solution, in order to better enable the sunlight collection mechanism to obtain as much sunlight resources as possible, the base 2 is preferably arranged on the top of the building.
