Further, the cavity is filled with a high refractive index solvent. A solvent with a high refractive index allows better light collection and refraction into the diffuser.

Further, the light collector, the guide fiber and the diffuser are all made of transparent materials. Transparent materials are used to make light collectors, guiding fibers, and diffusers to better collect light.

Further, the light collector, the conducting fiber and the diffuser are all made of acrylic resin or polycarbonate or epoxy resin or glass.

Further, a tapered light-gathering cover is provided outside the guide fiber. The conical condenser is used to reflect sunlight to the collector, thereby increasing the intensity of sunlight received.

Further, the outer surface of the guiding optical fiber is covered with a reflective coating. The reflective coating is made of silver or aluminum, which has a good reflective effect, reflects all the light collected by the light collector to the diffuser, and guides sunlight into the room for indoor lighting.

Further, both the light collector and the guide fiber are cylindrical structures.

Further, the diffuser is a spherical structure. The diffuser with spherical structure can introduce sunlight into the room to illuminate a wider range of the room.

Further, the surface of the diffuser is a corrugated surface. The surface of the diffuser is a diffuse reflection surface of the corrugated surface, which has the effect of scattering light.

Working principle of the present invention is:

When using and installing, the light collector is located at the outer end of the board room or the roof, facing the sun to collect light, the conductive fiber is used to transmit light to the diffuser, and the diffuser is located on the top of the indoor roof to scatter light. The hollow cavity structure inside the optical device, the guiding fiber and the diffuser enhances the intensity of receiving sunlight, and the sunlight is introduced into the room for indoor lighting.

The beneficial effects of the present invention are:

1. In the present invention, the diffuser has a spherical structure and a diffuse reflection surface, which is conducive to scattering light to every corner of the room and improving the illumination.

2. In the present invention, the cone-shaped light collecting cover is used to reflect sunlight to the light collector, thereby increasing the receiving intensity of sunlight.

3. The present invention is light in weight and easy to install. It can play the role of light guide only by adjusting the installation angle during use, and is especially suitable for use in construction sites and tunnels.
