Wireless Charging via Light Guide Plate and Photoelectric Array

The patent divides the photoelectric conversion function into multiple discrete photoelectric conversion devices arranged in an array. Each device operates independently to convert light energy to electrical energy, allowing the system to achieve high power transmission capability while maintaining a compact form factor. The segmented approach enables better spatial utilization and reduces the area required compared to a single large photoelectric conversion device.

The patent segments the light reception and energy conversion function across multiple photoelectric conversion devices. By distributing the incident high-luminance light across multiple smaller conversion elements rather than concentrating it on a single device, the thermal load on each individual device is reduced. This segmentation prevents overheating and thermal damage while maintaining high energy utilization efficiency through the collective action of all devices in the array.

The patent employs a segmented array of photoelectric conversion devices that can be configured in different patterns and densities. This modular segmented structure allows the system to adapt to various charging coverage requirements without increasing overall device complexity. Each segment can be independently controlled and optimized, enabling flexible deployment for different application scenarios while maintaining a relatively simple overall device architecture.
