Claim 6:
7. A variable-focus lighting system comprising:
a light source installed in an interior space so as to emit light in the interior space;
a first variable-focus lens on which light from the light source is incident and which is configured to be flexibly deformed;
a second variable-focus lens on which light having passed through the first lens is incident and which is configured to be flexibly deformed;
a first driver connected to the first variable-focus lens so as to deform the first variable-focus lens in a lateral direction of the interior space when a command signal is input;
a second driver connected to the second variable-focus lens so as to deform the second variable-focus lens in the forward/backward direction of the interior space when a command signal is input; and
a controller configured to transfer, based on input desired lighting, command signals to the first driver and the second driver to deform the first variable-focus lens and the second variable-focus lens so that a position and a type of light that is emitted satisfy the desired lighting.
