Claim Text:
1. An ambient lighting control system, comprising: an energy storage element, a light energy collecting element arranged to charge the energy storage element, a transmitter arranged to provide, in response to becoming connected with the energy storage element, signal using energy stored by the energy storage element, switching circuitry arranged to connect the energy storage element to the transmitter in response to an energy stored by the energy storage element exceeding a threshold energy, so that a number of signals provided by the transmitter during a time interval is proportional to a light intensity at the light energy collecting element, a controller comprising a receiver arranged to receive the signal from the transmitter, and circuitry arranged to determine the number of signals received from the transmitter during the time interval, and to output a control signal based on the determined number of received signals for controlling an amount of ambient lighting.
