<p>A light emitting charger (100) is provided. The light emitting charger delivers light energy to a portable electronic device (105) having a rechargeable battery. The electronic device is equipped with a photovoltaic energy conversion device that converts the transferred light into an electrical current that can be used to charge the battery. Through alternate communication mechanisms, the electronic device can alert the charger as to when to illuminate the light sources (102, 115) and which light sources to illuminate. The charger is equipped with photo detectors (103, 116) for receiving photo communication from the electronic device. In one embodiment, the charger periodically pulses one or more light sources until it receives light (113) reflected from reflective material (107) disposed along the electronic device. When the reflective light (113) is received, the charger may actuate a plurality of light sources (102, 115) in a predetermined pattern corresponding to the amount or location of the reflective light. In another embodiment, the electronic device is equipped with a photo communication light source, and may communicate with the charger through pulsed light.</p> |
