Wireless optical charging and power supply

Abstract

Wireless optical charging and power supply, which are echniques for charging electronic devices, are presented. A charger controller component controls supplying power to an electronic device having a solar cell component using optical charging. The charger controller component detects a shape and position of the electronic device located on a charger substrate component. The charger controller component identifies a subset of a plurality of light sources associated with the charger substrate component that correspond to the shape and position of the electronic device, and controls illumination of the light sources to illuminate the subset of light sources. The illumination of the subset of light sources provides optical waves to the electronic device that are converted to electrical energy to charge a power component of the electronic device. An optical processing element can employ an array of lenticular lens or microlens that can expand coverage of each light source and enhance uniformity of the illuminated area.

Description

technical field [0001] The subject disclosure relates generally to power supplies, and in particular to wireless optical charging and power supplies. Background technique [0002] With the rapid development of portable electronic devices, charging the batteries of these portable electronic devices has become a significant problem. While charging by cable or docking may be somewhat effective, it may be inconvenient to carry and / or search for the appropriate cable and charger for one or more portable electronic devices in a public area. Furthermore, charging portable electronic devices in public areas can be problematic, as charging platforms in public areas may have to provide different charging resources and / or charging facilities for various types of portable electronic devices, and may be expected Handle charging requests from a large number of consumers. [0003] One solution could be to use a wireless charging infrastructure, where the charger could be in the form of a...

Problems solved by technology

However, electromagnetic coupling has certain disadvantages as it may cause undesired interference with other electronic devices that may be sensitive to electromagnetic waves and / or entities that may have magnetically responsive substances embedded therein (e.g. hard drives, credit cards, etc.)

Also, it is uncertain whether large charging areas using electromagnetic coupling are dangerous to human health when higher powers are expected to provide large charging areas (e.g., charging tables)
