Device and method for receiving and converting laser into electric energy output

Abstract

The invention discloses a device and a method for receiving and converting laser into electric energy output. The device comprises an optical assembly, a photoelectric conversion assembly and a measurement and control assembly, wherein the measurement and control assembly comprises a measurement assembly and a control assembly; the measurement and control assembly can control a bearing platform toadjust the posture; and the measurement and control assembly and the optical assembly are arranged in a three-way type shell. A cavity sphere is adopted to construct a laser multi-reflection condition, and 2N photovoltaic cell pieces with special shapes are inlaid on the inner surface of the spherical cavity according to a certain rule, and the received laser energy is converted into electric energy to the maximum extent by utilizing the multi-reflection effect of the spherical cavity, so that the laser can be continuously and stably received and efficiently converted, and laser beam automatic alignment and tracking functions are achieved; the whole device is designed into a plug-in type radiator structure and is convenient for heat dissipation; and the overall water-proof sealing designis adopted, so that the device is particularly suitable for application occasions, such as an air vehicle hanging cabin adopting air flow for heat dissipation and a ship submersible trailer adopting water flow for heat dissipation.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a device and method for receiving and converting laser light into electric energy output. Background technique [0002] At present, wireless charging technology originates from wireless power transmission technology, and can be divided into two methods: low-power wireless charging and high-power wireless charging. Low-power wireless charging often adopts electromagnetic induction, such as the Qi method for charging mobile phones. High-power wireless charging often adopts the resonant type (most electric vehicle charging uses this method), and the power supply equipment (charger) transmits energy to the power-consuming device, and the device enables the received energy to charge the battery and simultaneously supply it. for its own operation. Since energy is transmitted between the charger and the power-consuming device by a magnetic field, the two are not c...

AI Technical Summary

Problems solved by technology

At present, one of the main difficulties of laser wireless charging is that the photoelectric conversion efficiency of the receiving device is too low, the working temperature of the conversion element is too high to further deteriorate the conversion efficiency, and the equipment is bulky and inconvenient to install.
