Abstract
A charging device configured to charge a mobile device through the solar cells integrated on the mobile device. The charging device converts wall power to light energy which can be absorbed by the solar cells and then converted to electricity for storage in the rechargeable battery of the mobile device. The charging device includes a light source configured to emit a light beam having a spectrum tuned to the spectral response of the solar cells. The charging device includes a proximity sensor for detecting the presence of a mobile device within the charging device housing and responsively signaling the activation of the light source. The charging device includes logic for wirelessly communicating with the mobile device as well as controlling the charging process in various stages and aspects. The light source may be LEDs that also serve to transmit light communication signals to the mobile device.
