Problems solved by technology
[0002] The advantages of high energy density, small divergence angle, and good directionality make laser play a strong technical advantage in the field of wireless energy transmission. However, although lasers, photovoltaic cells and related optical technologies for laser wireless energy transmission have matured , but no mature laser wireless energy transfer system has been widely used. The main reason is that the output power of the laser wireless energy transfer system is low, and the photoelectric conversion efficiency is far lower than that of a single photovoltaic cell.

The invention discloses a laser wireless energy transmission system based on a light splitting device. The system comprises a laser emitting device for emitting laser, a light splitting device used for receiving the laser and splitting the laser into n parts of split light with the same luminous flux, and a hollow spherical photovoltaic receiver used for receiving the split light and converting the split light into electric energy; the center of the hollow spherical photovoltaic receiver is provided with n light splitting supports which are uniformly distributed outwards in a radial manner. The n light splitting supports are used for fixing output optical fibers of the light splitting device; therefore, the n parts of split light with the same luminous flux are correspondingly and directlyirradiated to a 360 / n-degree solid angle area of the hollow spherical photovoltaic receiver; each area of the inner wall of the hollow spherical photovoltaic receiver can be ensured to be directly irradiated by the laser by adopting a mode of splitting the laser; difference of illumination intensities of different areas is reduced, the closed hollow structure of the hollow spherical photovoltaicreceiver is further utilized, the energy of the laser is repeatedly utilized, and the photoelectric conversion efficiency and the output power of the laser wireless energy transmission system based onthe light splitting device are improved.

technical field [0001] The present invention relates to the technical field of wireless energy transmission, in particular to a laser wireless energy transmission system based on a spectroscopic device. Background technique [0002] The advantages of high energy density, small divergence angle, and good directionality make laser play a strong technical advantage in the field of wireless energy transmission. However, although lasers, photovoltaic cells and related optical technologies for laser wireless energy transmission have matured , but no mature laser wireless energy transfer system has been widely used. The main reason is that the output power of the laser wireless energy transfer system is low, and the photoelectric conversion efficiency is far lower than that of a single photovoltaic cell. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is tha...
